Description

{Atomizing Apparatus for Preventing from Dust Scattering}

The present invention relates to a spray device for preventing dust from flying by spraying water at high pressure to increase the contact efficiency of dust with the sprayed water, thereby preventing dust from flying, thereby reducing environmental pollution and promoting air purification.

In general, construction sites and other places generate dust due to wind, etc., which pollutes the surrounding environment and air.

In order to increase the spraying efficiency of the spraying device, it has been proposed to provide a blower inside the housing and a spray nozzle at the front of the housing so that water sprayed by the spray nozzle is scattered by the blower's air, thereby increasing the contact area with dust and thus increasing the spraying efficiency of the spraying device.

An example of a spraying device is Korean Utility Model No. 20-0110808 (title of the invention: Liquid sprayer), which is illustrated in FIG. 1 and FIG. 2.

The above liquid sprayer is configured to be capable of spraying various liquids in a directional manner by installing a rotating frame (10) having a blower means and a sprayer means that can be angle-adjusted and selectively rotated on a frame (1) to which a moving means is attached, and the blower means has a protector (15, 15') fixed front and rear, and a blower fan (14) installed inside a blower pipe (11) that is angle-adjustable by a pin (12) on the rotating frame (10), and an air volume controller (16) installed in front of the blower fan (14), and the sprayer means has a spray pipe (18) having a plurality of spray nozzles (17, 17') that are fitted onto a connecting pipe (20) by a connecting piece (19) whose length is adjusted on the front side of the blower pipe (11); The rotation means of the above rotation frame (10) is characterized by fixing the rotation frame (10) to the upper part of a driven shaft (6) on which a bevel gear (5') that engages and rotates vertically with a bevel gear (5) inserted on a driving shaft (4') of a geared motor (4) installed on a base (2) is inserted.

The above liquid sprayer is configured so that the blower tube (11) can be adjusted at an angle in the up-and-down direction and rotated left-and-right so that the angle can be adjusted in the left-and-right direction.

Another example of a spray device is a method of increasing the spraying efficiency by arranging spray nozzles in two rows as a means of increasing the efficiency of preventing dust from flying, which is disclosed in Patent Publication No. 10-2011-0062045 (Title: Spraying Watering Device), and is illustrated in Figure 3.

The above-described spray watering device comprises: a housing having an opening; a blower (20) provided in the housing and blowing air in the direction of the opening; a first spray pipe (100) spaced apart from and arranged in front of the blower and having a plurality of first spray nozzles (110) and supplying water; and a second spray pipe (200) arranged in parallel with the first spray pipe and having a plurality of second spray nozzles (210) and supplying water.

However, the above-mentioned spray nozzle has the advantage of being able to spray water at different spray angles by the first spray nozzle (110) and the second spray nozzle (210), thereby providing a wide spraying range and being able to control the spraying range and spraying distance. However, since the housing (10) is hinged so that it can only rotate up and down, the housing (20) cannot rotate left and right, which has the disadvantage that the spraying range is limited.

In addition, since the direction of the blown wind is fixed only to the front and contact with the dust depends only on the spray angle of the nozzle, there is a problem that the dust removal efficiency is not high.

Accordingly, the purpose of the present invention is to provide a spraying device for preventing dust from flying, which increases the contact efficiency with dust by causing the mist sprayed from the spraying head to generate a vortex, thereby improving the anti-flying performance.

In addition, another object of the present invention is to provide a spraying device for preventing dust from flying, which enables the spraying area of the mist to be adjusted by changing the angle of the spraying head.

In order to achieve the above object, the spraying device for preventing dust scattering of the present invention is characterized by including: a base frame that is fixed or movable to the ground around a construction site; a head housing that is installed on the base frame so as to be able to rotate left and right and adjust the angle up and down, a plurality of nozzles that are installed on the front of the head housing to spray water on the construction site, a blower unit that is installed on the inner rear part of the head housing to blow away the water sprayed from the nozzles, and a vortex generating member that is installed inside the head housing but is installed in front of the blower unit to generate a vortex by applying a rotational force so that the air blown from the blower unit to the nozzles rotates in one direction, thereby scattering the water sprayed from the nozzles; an up and down spray angle adjusting unit that is installed between the base frame and the spray head to adjust the spray angle in the up and down direction; and a left and right spray angle adjusting unit that is installed on the base frame to adjust the spray angle in the left and right direction by horizontally rotating the spray head.

In addition, the left-right spray angle adjustment unit is characterized by including a bearing housing provided on the upper surface of the base frame and having a bearing built in to rotatably support the spray head, a support bracket provided on the upper side of the bearing housing and having a rotating shaft fixed thereto that is rotatably supported by the bearing, and a hinge frame provided on the outer surface of the spray head and hinge-connected to the support bracket so as to be angle-adjustable up and down.

In addition, it is preferable that the spray angle adjustment unit include a piston having one end hingedly connected to a base frame and the other end hingedly connected to a side of a spray head, and a cylinder that changes the angle of the spray head by introducing and withdrawing the piston.

In addition, the left-right spray angle adjustment unit is characterized by including a rotary motor fixed to the support bracket, a reducer connected to the drive shaft of the rotary motor to reduce the rotational power of the rotary motor, a drive gear connected to the reducer, and a driven gear meshed with the drive gear and fixed to a rotary shaft located on the upper side of the bearing housing.

As described above, the spray device for preventing dust from flying has a spray head that is rotated horizontally on a base frame by a left-right spray angle adjustment unit, and can adjust the spray angle up and down by a spray angle adjustment unit. Since the moisture sprayed by the spray head is scattered by generating a vortex, the dust at a construction site is combined by increasing the contact rate with the sprayed moisture, and thus the dust flying prevention performance can be improved.

In addition, the spraying device for preventing dust from flying according to the present invention can effectively prevent dust from flying by measuring the amount, direction, and wind speed of dust flying to identify the area where dust is flying and spraying water.

Figures 4 and 5 are photographs showing a spraying device for preventing dust from flying according to the present invention.
Figure 6 is a drawing showing a state in which a spray head is installed on a base frame in a spraying device for preventing dust scattering according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

A spraying device for preventing dust scattering according to one embodiment of the present invention comprises a base frame (10); a spraying head (20); a vertical spray angle adjusting unit (30); and a left-right spray angle adjusting unit (40).

The above base frame (10) may be fixed to the floor around the construction site or may be provided with wheels on the bottom so that it can be moved (see Fig. 6).

The spray head (20) is installed on the base frame (10) so as to be able to rotate left and right and adjust the angle up and down, and includes a head housing (21), a plurality of nozzles (22) installed on the front side of the head housing (21) to spray water on a construction site, a blower unit (23) installed on the inner rear side of the head housing (21) to blow away the water sprayed from the nozzles (22), and a vortex generating member (24) installed inside the head housing (21) but in front of the blower unit (23) to generate a vortex by applying a rotational force so that the air blown from the blower unit (23) to the nozzles (22) rotates in one direction, thereby causing the water sprayed from the nozzles (22) to scatter.

The above-mentioned vertical spray angle adjustment part (30) is installed between the base frame (10) and the spray head (20) and serves to adjust the vertical spray angle of the spray head (20).

The above-mentioned left-right spray angle adjustment part (40) is installed on the base frame (10) and serves to adjust the left-right spray angle by horizontally rotating the spray head (20).

These spraying devices are placed in multiple locations at regular intervals around the construction site, and one of the spraying devices is selected based on the wind direction and wind speed to spray.

The spray head (20) includes a head housing (21), a plurality of nozzles (22) installed in the front of the head housing (21) to spray water on a construction site, and a blower unit (23) installed in the inner rear portion of the head housing (21) to blow away the water sprayed from the nozzles (22).

The head housing (21) is formed in a cylindrical shape with the front and rear sides open, and a blower unit (23) is mounted on the inner rear portion. A vortex generating member (24) is provided inside the head housing (21) in front of the blower unit (23). In addition, a nozzle (22) is provided on the front end of the head housing (21).

The above nozzles (22) are provided at the front end of the head housing (21), and are arranged in multiple rows at regular intervals in the circumferential direction and in multiple rows in the axial direction. In the drawing, the nozzles (22) are shown in two rows.

The above nozzle (22) is mounted on a nozzle mounting portion, and a plurality of channels for supplying water to each nozzle (22) are formed, and a chamber into which pumped water flows is formed on the outside of the nozzle mounting portion. That is, after water flows into the chamber, it is distributed to each nozzle (22) through the channels and sprayed.

The blower unit (23) includes a blower motor fixed to the inner surface of the head housing (21) by a mounting bracket, and a blower fan mounted on the drive shaft of the blower motor to blow air.

When blown by the above blowing unit (23), water particles sprayed through the nozzle (22) combine with the blown wind to form fine fog. At this time, the diameter of the formed fine fog is 3 to 24 ㎛. The formed fine fog enables the capture of fine dust of 10 ㎛ or less and ultrafine dust of 2.5 ㎛ or less, and also lowers the surrounding temperature through rapid evaporation of the fine fog. The pumping pressure of the pump for spraying water through the nozzle (22) is set to be high pressure pumping of 60 to 70 bar, and the diameter of the nozzle is 0.08 to 0.5 mm.

The table below shows the amount of fine fog sprayed and the droplet diameter according to the nozzle diameter.

In addition, a filter is provided to purify the water supplied by the pump so that purified water is supplied.

The above vortex generating member (24) is installed inside the head housing (21) and in front of the blower unit (23) to generate a vortex by adding a rotational force so that the air supplied from the blower unit (23) to the nozzle (22) rotates in one direction, thereby blowing the air and scattering the water sprayed from the nozzle (22). The above vortex generating members (24) are mounted in multiple numbers in the circumferential direction on the inner surface of the head housing (21) and are formed to be inclined at a certain angle in the air discharge direction so as to generate a vortex by the wind blown by the blower unit (23) and blow the air. In addition, it is preferable that the above vortex generating members (24) have a streamlined cross section to reduce the resistance of the wind blown by the blower unit (23) and enable long-distance blowing.

The wind blown from the above blowing unit (23) generates a vortex by the above vortex generating member (24) to cause the water sprayed by the nozzle (22) to fly, thereby increasing the contact rate between the dust and the sprayed moisture at the construction site and allowing them to combine, thereby improving the dust flying prevention performance.

The upper surface of the base frame (10) is provided with the left-right spray angle adjustment part (40), and the left-right spray angle adjustment part (40) includes: a bearing housing provided on the upper surface of the base frame and having a bearing built in that rotatably supports the spray head; a support bracket provided on the upper side of the bearing housing and having a rotating shaft fixed thereto that is rotatably supported by the bearing; and a hinge frame provided on the outer surface of the spray head and hinge-connected to the support bracket so as to be angle-adjustable up and down.

Here, inside the bearing housing, a ball bearing that axially supports a rotating shaft to which a spray head (20) is connected and a thrust bearing that supports the load of the spray head are provided.

The above-mentioned vertical spray angle adjustment unit (30) is composed of an actuator having a structure in which one end is rotatably hinge-connected to a base frame (10) and the other end is rotatably connected to the side of a spray head (20) and moves in a straight line in the longitudinal direction.

The above-mentioned vertical spray angle adjustment unit (30) is composed of a piston whose first end is hinge-connected to the side of the spray head (20), and a cylinder whose rear end is hinge-connected to the base frame (10) and which allows the piston to be introduced and withdrawn by the cylinder. When the piston is introduced and withdrawn by the cylinder, the spray head (20) connected to the piston changes its angle in the vertical direction.

The above cylinder may be a solenoid type in which the piston moves in a straight line when power is applied, a pneumatic cylinder in which the piston moves in a straight line when air pressure is provided, or a hydraulic cylinder in which the piston moves in a straight line when hydraulic pressure is provided.

The above-mentioned left-right spray angle adjustment unit (40) includes a rotary motor fixed to a support bracket, a reducer to which the drive shaft of the rotary motor is connected to reduce the rotational power of the rotary motor, a drive gear connected to the reducer, and a driven gear fixed to a rotary shaft that is rotatably supported by a bearing housing and meshes with the drive gear.

In addition, it is preferable that the base frame (10) be equipped with a dust detection sensor (not shown) so that the spray head (20) can be rotated and angle-adjusted by the vertical spray angle adjustment unit (30) and the left-right spray angle adjustment unit (40) to the point where dust is generated, thereby enabling spraying to the point where dust is generated.

In addition, when the point of dust generation is detected by the above dust detection sensor, a control unit is further provided to control the rotation and angle adjustment of the spray head (20) to the point where dust is generated by the above vertical spray angle adjustment unit (30) and the above left and right spray angle adjustment unit (40).

In addition, the control unit controls the spraying operation of the spraying head (20).

In addition, the base frame (10) is equipped with a temperature and humidity sensor (not shown), so that the temperature and humidity of the workplace can be controlled at the set temperature and humidity.

In addition, it is preferable that the chamber into which the pumped water flows is provided with a cooling unit and a heating unit so as to cool or heat the water to be pumped, thereby enabling temperature control of the water to be sprayed.

In addition, the present invention can control the operation of the spraying device remotely by a remote controller, and can also control the operation of the spraying device according to the working time by a timer.

In addition, the present invention provides a wind direction and anemometer to the base frame (10) to adjust the spraying direction of the spraying head (20) according to the wind direction and the blowing speed of the blowing unit (23) according to the wind speed, thereby achieving optimal spraying.

The above base frame (10) is further provided with a spray distance measuring unit for measuring the flying distance of water sprayed by the spray head (20), and it is preferable to further provide a server (not shown) that determines the optimal spray distance of the spray head (20) by using the spray distance data measured by the spray distance measuring unit according to the wind direction and wind speed data measured by the wind direction and anemometer and the left-right spray angle and the up-down spray angle.

In addition, the server is further provided with a database storing wind direction and wind speed data, spray distance data, left-right spray angle, and up-down spray angle data, and it is preferable that the wind direction and wind speed data, left-right spray angle, and up-down spray angle data are fed back to the database so that analysis information is machine learned, so that when the analyzed data is determined to have a similar pattern, the spray distance is determined using the data stored in the database.

Thus, the operation of the spray device for preventing dust scattering according to one embodiment of the present invention is described as follows.

First, the spray head (20) rotates in the direction in which dust is generated by the wind speed and direction at the construction site, and the spray angle is adjusted. That is, when the rotation motor of the left-right spray angle adjustment unit (40) is driven, the rotation shaft meshed with the rotation motor, the driving gear, and the driven gear rotates, and the spray head (20) rotates left-right in the direction in which dust is generated.

And, the cylinder of the vertical spray angle adjustment unit (30) is operated so that the vertical spray angle of the spray head (20) is adjusted by the introduction and withdrawal of the piston, so that the nozzle (22) of the spray head (20) faces the direction in which dust is generated.

In this state, when the pump is operated, water is sprayed from multiple nozzles (22) installed in the front of the head housing (10). Then, the blower unit (23) installed in the spray head (20) blows wind in the direction of the nozzles to send the water sprayed from the nozzles away.

At this time, the air blown from the blower unit (23) generates a vortex by the vortex generating member (24), and the water sprayed by the nozzle (22) is sprayed while rotating by the generated vortex, so that the dust at the construction site increases the contact rate with the sprayed moisture and combines, thereby improving the dust scattering prevention performance.

In this way, the spray device for preventing dust scattering according to the present embodiment can improve dust scattering prevention performance because the spray head rotates in the direction in which dust is generated and the spray angle is adjusted.

Although the present invention has been described and illustrated with specific preferred embodiments as examples, the present invention is not limited to the above embodiments, and various changes and modifications may be made by those skilled in the art without departing from the spirit of the present invention.
