Description

Filtration device and polishing wastewater reduction system for lens polishing wastewater {Apparatus for filtering polishing wastewater of lens and system for reducing the polishing wastewater}

The present invention relates to a lens polishing wastewater treatment device for separating and disposing of sludge and suspended substances from the spectacle lens polishing wastewater generated from the oxidizer, and more particularly, to a lens polishing wastewater treatment device generated when a plastic spectacle lens is polished with a lens polishing machine. It relates to a filtration device for lens polishing wastewater and a polishing wastewater reduction system that does not discharge polishing wastewater by separating and removing fine particles suspended in the polishing wastewater, such as lens particles, lens microparticles, and microplastics, and circulating the polishing water for reuse. .

In general, in the process of polishing a lens with a lens polishing machine, a lot of dust and particles are generated along with heat due to friction between the polishing means and the lens as a workpiece, which may result in a polishing defect.

In addition, the physical properties of the lens or the polishing means may be changed or damaged by heat generated during the polishing process.

In order to solve this problem, when processing a lens with a lens polisher, grinding water is supplied to the contact part between the grinding means and the lens to suppress the temperature rise of the grinding means and the lens, and to prevent dust from flying.

For example, because spectacle lenses are manufactured in a circular shape and spectacle frames are designed in various shapes, the edges of spectacle lenses are processed to match the shape and groove of spectacle frames with a so-called edger in order to stably fit spectacle lenses to spectacle frames.

When the diamond grindstone rotating at a speed of 3,000 to 6,000 rpm per minute sharpens lenses such as glasses lenses made of glass or plastic, high heat of 900 ° C or higher is generated due to friction in this oxidizer, to prevent damage to the lenses during polishing. A coolant is used that circulates grinding water, which acts as a lubricating and cooling agent, or contains a cleaning agent that increases grinding power by preventing corrosion inhibitors and foreign substances from adhering to the diamond grindstone.

Floating substances of fine particles such as lens particles, lens microparticles, and microplastics, which are generated during polishing of spectacle lenses in the oxidizer, are mixed with the polishing water and discharged into the polishing wastewater. After filtering and reusing the grinding water, if sludge is excessively generated and further filtration is difficult, it is discharged through the sewer.

However, the suspended matter contained in the abrasive wastewater has small particles, so it is not filtered by sewage treatment facilities and flows into rivers and seas through sewer pipes, which is highly likely to cause secondary pollution of fish and shellfish and marine ecosystems.

That is, the polishing wastewater contains carcinogenic or suspected substances such as dichloromethane, chloroform, phenol, cyanide, 1.4-dioxin, formaldehyde and heavy metals, and has a COD value of 6 to 13 times the standard value, and SS (suspended matter) As it is 25 to 31 times higher than the standard value, there is a problem that causes serious water pollution and environmental pollution.

Accordingly, the recent Enforcement Regulations of the Water Environment Conservation Act (revision on October 17, 2019; enforcement on January 1, 2021; report on June 30, 2021) stipulates that the lens polishing wastewater of opticians should be managed within the legal system. According to the amended Enforcement Regulations of the Water Environment Conservation Act, external discharge (sewer) of lens polishing wastewater is prohibited from January 2021. It is mandatory to report voluntarily.

According to the Enforcement Regulations of the Water Environment Conservation Act, if the facility that manufactures lenses in an optical shop, which is divided into installations and managers of other water pollutants, treats wastewater below the permissible discharge standard and intends to discharge it, treatment with appropriate methods such as filtration to remove water pollutants In the case of filtration, a filtration device with an average pore size of 10 μm or less or equivalent or higher performance made of a material such as a non-woven fabric should be used, and the sludge generated at this time should be periodically removed to ensure that the filtration device functions properly. should be kept

In Patent Document 1, when the grinding water flowing into the storage tank is turbid, the grinding water is supplied to a filtration tank having a filtration filter on the inner lower side, and the grinding water falls into the lower storage tank by its own weight so that foreign substances are filtered by the filtration filter. A method and a regenerating apparatus for regenerating lens abrasive water for removing moisture from foreign substances loaded in the heater member and then removing are disclosed.

This can reduce water consumption through filtration and reuse of abrasive wastewater, and effective filtration of abrasive particles can be achieved by using a fiber filter to filter the abrasive wastewater. Because of the frequent clogging of the filter, frequent replacement of the filter is unavoidable, resulting in poor economic efficiency.

In order to solve this problem, Patent Document 2 discloses a first filter that filters foreign substances with a diameter of 1 mm or more at the inlet of a water collecting tank that collects abrasive wastewater discharged from the oxidizer, and a filter that filters foreign materials with a diameter of 1 mm or more at the outlet of the collecting tank. and a sludge filtration net that filters only sludge inside the collection bin, and transmits high-frequency vibration to the abrasive wastewater collected therein to improve sludge agglomeration and prevent clogging of the sludge filtration net. An abrasive wastewater treatment apparatus for moisture is disclosed.

However, since the first filter and filter are of a metal mesh type, they can be disassembled and washed and reused. However, when the processing amount of the lens is large, the filter is frequently clogged by abrasive particles, which is a considerable inconvenience that the filter must be disassembled and cleaned frequently There is a problem that comes with loneliness and discomfort.

In addition, despite the use of grinding water and cooling water during lens processing, due to the high heat generated by friction, dust and combustion gases containing carcinogenic or suspected substances are spread in the work space, causing severe odors and harmful to the health of workers. There is a problem that adversely affects.

Therefore, polishing wastewater can be efficiently filtered and reduced without frequent replacement, disassembly, and washing of filters, and can be reused as polishing water, and fine particles suspended in the abrasive wastewater such as lens particles, lens fine particles, and microplastics are efficiently filtered. There is a need for a lens polishing wastewater filtration device and abrasive wastewater reduction system that can remove and remove odors and improve the working environment that inevitably inhales odors and carcinogenic substances or suspicious substances.

1 to 8, the lens polishing wastewater reduction system according to the present invention stores the polishing wastewater to be supplied to the lens polishing machine (hereinafter referred to as 'Oxidizer') 10, and polishes the lens from the Oxidizer 10. When there is a processing signal, the polishing water tank 100 for pumping the stored polishing wastewater to the filtering device 200 by driving the submersible pump 120, and filtering the polishing wastewater pumped from the polishing water tank 100, It includes a filtration device 200 for supplying moisture (10).

In addition, a deodorizing device 300 that inhales and decomposes smoke (air containing ultra-fine particles that emit odor while dispersed in the air) generated during lens polishing in the oxidizer 10 and discharges the odor into clean air that has been adsorbed and removed. may further include.

That is, the deodorizing device 300 collects the air (G1) flowing in together with the abrasive wastewater (W1) collected in the abrasive water tank (100) from the oxidizer (10) through the intake pipe connection part (350), thereby reducing odor and carcinogenicity. After filtering ultra-fine particles containing sexual or suspicious substances, they are discharged into clean air (G2).

Therefore, the polishing wastewater W1 of the oxidizer 10 generated when the lens is polished using the polishing water supplied from the filtering device 200 is collected into the polishing water tank 100 and is pumped into the submersible pump 120 . A circulation cycle is made in which the grinding water is supplied to the oxidizer 10 again in a filtered state by being pressurized to the filtering device 200 by the filtration device 200 .

In addition, the air (G1) mixed with ultra-fine particles containing odor and carcinogenic substances or suspected substances generated by lens polishing in the oxidizer (10) is filtered by the deodorizer (300) and discharged as clean air (G2) can do.

That is, the polishing wastewater (W1) mixed with the lens particles (P1) and the lens fine particles (P2) generated when the lens is polished in the oxidizer 10 is the oxidizer located in the lower part of the oxidizer 10 by its own weight. The water is collected in the abrasive water tank 100 through the connection unit 101 .

The octopus connection part 101 has a large diameter so that it can be directly applied to a variety of oxidizers 10 irrespective of the shape or type of the oxalic appliance 10 .

An upper portion of the abrasive water tank 100 is provided with a sieve 110 for primary filtering of relatively large lens particles P1 and the like contained in the abrasive wastewater W1.

The sieve 110 is a relatively large lens particle (P1) and a lens that may fall into the abrasive water tank 100 during or before and after processing so that the filtering function is not reduced due to clogging of the hole in a short time. It may be made of a mesh filter of 20 to 30 mesh.

That is, the sieve 110 has the advantage that it does not require frequent replacement or washing by allowing the polishing wastewater W1 to be filtered smoothly for a long time.

After the lens particles P1 are filtered from the sieve 110, the polishing wastewater W2 collected in the polishing water tank 100 contains lens fine particles P2 that cause serious pollution in the ecosystem.

The polishing wastewater W2 collected in the polishing water tank 100 is pumped to the filtering device 200 by the submersible pump 120 together with the lens fine particles P2.

During the initial operation of the polishing wastewater reduction system, the oxidizer 10 stores an appropriate amount of the polishing water supplied for lens polishing processing, and when the operation continues for a certain period of time, it is naturally evaporated and filtered at the same time as the filtering device 200. It is removed together with a pile of lens fine particles (P2) (hereinafter referred to as 'sludge') to reduce the amount of water stored therein.

Therefore, the abrasive water tank 100 needs to supplement the abrasive water in order to properly maintain the amount of water stored therein.

The abrasive water tank 100 is preferably made of a transparent material so that the amount of water stored can be checked from the outside, and a scale indicating the minimum amount of water may be formed on the side to maintain an appropriate amount of abrasive water required for lens polishing processing.

In addition, since an extra space is required in the polishing water tank 100 due to bubbles generated in the process of polishing the lens by the occupant 10, it is preferable to form a scale indicating the maximum amount of water as well as the minimum amount of water.

When the storage amount of the abrasive water tank 100 falls or is expected to fall below the minimum storage amount, the polishing water is supplied through the oxidizer 10 or the maximum storage amount is lowered through the tank cover 130 of the polishing water tank 100. Polishing water can be replenished.

On the other hand, since the lens fine particles (P2) are attached to the bubbles generated in the process of polishing the lens by the oxidizer (10), if the bubbles are not removed, the lens fine particles (P2) attached to the bubbles are stored in the polishing water tank. It does not settle into the abrasive wastewater (W2) in (100).

Therefore, it is preferable to inject the antifoaming agent into the oxidizer 10 or the abrasive water tank 100 in order to suppress and remove bubbles generated in the process of polishing the lens by the oxidizer 10 .

Here, the spray nozzle 140 is preferably made of a spiral cone spray nozzle so that the diffusion spray of the polishing wastewater occurs.

In addition, a blocking wall 131 is formed on the lower surface of the tank cover 130 to prevent the abrasive wastewater sprayed from the spray nozzle 140 from splashing out and leaking to the outside.

And a plurality of tubes 150 for supplying the polishing wastewater to the inner bottom of the polishing water tank 100 so that the polishing wastewater flows in the polishing water tank 100 are connected to the branch pipe L3.

That is, the tube 150 may cause a natural flow of the abrasive wastewater in order to prevent the microplastic powder mixed in the abrasive wastewater in the abrasive water tank 100 from settling in a corner or floor far away from the submersible pump 120 .

Here, a diffuser 151 for spreading and spraying the polishing wastewater discharged from the tube 150 in all directions may be mounted at the front end of the tube 150 as shown in FIG. 12 .

The filtering device 200 receives the polishing wastewater (W2) from the polishing water tank 100, separates the lens fine particles (P2) mixed in the polishing wastewater (W2), and stacks them on the floor, and the lens fine particles (P2) are The filtered reduced water (W3) is supplied to the oxidizer (10) as abrasive water.

The casing 211 is formed in a tapered shape such that the polishing wastewater pumped by the submersible pump 120 flows in from the upper part and is discharged to the lower part to form a rotational flow so that the diameter gradually decreases from the upper part to the lower part.

The mesh network 212 has an outer circumferential surface in close contact with the inner circumferential surface of the casing 211, and is formed in an inverted truncated cone shape in which a plurality of troughs are radially formed in order to maximize the cyclone phenomenon on the inner circumferential surface.

Here, the mesh network 212 is preferably cut into a fan-shaped or trapezoidal shape so as to be in close contact with the inner wall of the casing 211 and then rolled into a circular shape and inserted into the casing 211 .

That is, the nonwoven fabric bag 214 is in close contact with the inner circumferential surface of the mesh network 212 by the abrasive wastewater discharged to the lower part while the outer circumferential surface of the casing 211 forms a rotational flow from the upper part of the casing 211, and in the abrasive wastewater The reduced water removed by filtering the fine particles suspended in it is discharged to the outside.

In addition, the nonwoven fabric sack 214 is separated from the polishing wastewater W2 and the polishing wastewater W2, which flows into the upper inlet 220 and forms a rotational flow when the filtering device 200 is operated, and is the lower portion of the filter 210 . The inlet is fixed with the inlet open by the fixing ring 213 which is forcibly fitted on the upper part of the casing 211 so as to contain the lens fine particles P2 accumulated in the .

Accordingly, by removing the nonwoven fabric bag 214 when the filtering device 200 is stopped, the lens fine particles P2 stacked therein can be simply and neatly removed from the filtering device 200 at once.

That is, the nonwoven sack 214 is loose enough to allow the lens fine particles P2 to pass therethrough, but the lens fine particle (P2) sludge stacked on the floor through the cyclone principle remains in the nonwoven sack 214. and only the reduced water W3 from which the lens fine particles P2 are separated is discharged through the nonwoven fabric bag 214 .

On the other hand, since some polishing wastewater (W2) remains in the sludge contained in the nonwoven fabric bag 214, an absorbent coagulant that absorbs and solidifies the moisture of the remaining polishing wastewater (W2) is added to the sludge with high viscosity and the polishing wastewater (W2) It can be transformed and solidified in the form of small particle powder and then disposed of easily by separating it out and putting it in a volume-based bag.

When the driving of the submersible pump 120 is stopped because the reduced water W3 is discharged through the lower outlet 230 and the pressure in the filtration device 200 becomes higher than the pressure of the submersible pump 120, the filtration device 200 The air inside moves along the abrasive wastewater pipe (L1) and fills the submersible pump (120) with air.

When the submersible pump 120 is filled with air, since the submersible pump 120 does not operate, it may be troublesome and troublesome to have to bleed air from the abrasive wastewater pipe L1 before driving the oxidizer 10. .

To solve this, an air pocket 500 is provided in the middle of the abrasive wastewater pipe L1 connected from the submersible pump 120 to the filtration device 200 .

A submersible pump side connection part 530 connected to the submersible pump 120 is located at the lower portion of the air pocket 500 , and a filtration device side connection unit 540 connected to the filtration device 200 is located at the upper side, and an air buffer 510 is located inside the air pocket 500 . ) and a polishing wastewater buffer 520 are formed.

Therefore, when the submersible pump 120 is stopped, the air in the filtration device 200 having a relatively high pressure rides the abrasive wastewater pipe L1 and flows into the air buffer 510 through the filtration device side connection part 540 .

At this time, as it meets the air buffer 510 having a wider space than the abrasive wastewater pipe (L1), the pressure of the backflowing air is lowered, and thus the abrasive wastewater (W2) filling the inside of the air pocket 500 is pumped into the submersible pump ( By losing the force to push up to 120), the submersible pump 120 can be normally driven when the oximeter 10 is driven again.

The lens polishing wastewater filtering device and the polishing wastewater reduction system including the same according to the present invention configured as described above, efficiently filter and circulate polishing wastewater for a long time without frequent replacement or washing of the filter that filters out lens fine particles, so that it can be reused as polishing water. and suspended substances such as lens particles and lens fine particles can be effectively filtered and removed from the abrasive wastewater.

In addition, it is possible to maintain a clean working environment by removing odors and carcinogenic or suspicious substances generated during lens polishing.

That is, the sludge with large particles, bubbles, etc. are separated from the sieve 100 in the grinding water tank 100 , and the small sludge and the grinding water are moved through the submersible pump 120 . The odor generated in this process may be deodorized by the deodorizing device 300 .

In addition, the filter 210 of the filtering device 200 can purify the polishing wastewater by separating the sludge contained in the polishing wastewater and reuse it as polishing water.

In addition, it is possible to process several lenses in succession, and it is possible to create a clean working environment for the abrasive machine because polishing wastewater does not accumulate and circulates continuously.

In addition, the water contained in the filtered sludge can be completely removed so that it can be conveniently separated and discharged, and it can be used universally regardless of the shape or type of the lens polisher.

On the other hand, the present invention is not limited by the above-described embodiment and the accompanying drawings, and can be variously modified and applied in various ways not illustrated within the scope without departing from the technical spirit of the present invention, as well as each It is apparent to those of ordinary skill in the art to which the present invention pertains that it can be widely applied by changing the substitution of components and other equivalent embodiments.

Therefore, the contents related to the modification and application of the technical features of the present invention should be interpreted as being included within the technical spirit and scope of the present invention.
