Description

Non-powered collection and lifting coupling device for sewage contaminant removal {THE NONPOWER COMBINATION APPARATUS FOR SEWAGE ADULTERATION REMOVA}

The present invention relates to a powerless coupling device in which a structure for collecting and lifting impurities mixed in classified sewage is integrated. It is possible, and it can be monitored using smart devices, so that the safety of workers is guaranteed first and the failure of the pump in the subsequent stage can be prevented in advance.

In general, sewage contaminated with liquid or solid substances due to human life or economic activities is transported to a sewage treatment facility (C) through a sewage pipe. It is composed of three types of auxiliary facilities including pipeline (PL), manhole (MH) and relay pumping station (PS), and the sewage is transferred to the treatment facility with the power of pump (P). Among the roles of each of the three components of the sewage pipe, first, the pipeline (PL) is a pipeline that collects generated sewage and moves it by natural flow or pump pressure, and the manhole (MH) allows people to come in and out for cleaning or inspection of the pipeline. The relay pumping station (PS) is installed when it is difficult to transport sewage with natural flow or when the depth of pipeline is significantly deep and construction and management are difficult. For this reason, the relay manhole pumping station (PS) is a structure that is mostly buried underground and is located in a treatment area adjacent to a private house, requiring special attention and management at all times.

Among some of the solid substances that flow into the pipeline (PL) mixed with sewage, which is mostly liquid, there are mixed substances that cause pump failure or hinder normal operation of the relay pumping station (PS), such as toilet paper, women's items, dishcloths, scrubbers, etc. There are many. The failure of the pump (P) or the impediment to operation that can occur due to such impurity does not stop at the normal pumping of the sewage, and untreated sewage may overflow from the relay pumping station (PS) and the upper manhole (MH), and furthermore In some cases, it causes a situation in which sewage cannot be drained at home, causing serious civil complaints.

As a means to solve the above problems, a fixed or detachable screen for removing impurities is installed inside the relay pump station (PS) where the pump (P) is installed or the manhole (MH) upstream before the relay pump station, the relay pump station ( PS) and upstream manholes (MH) are often deep due to the nature of the location, and since the screen is installed at the bottom of the manhole, there is no risk of safety accidents when management approaches the screen or removes impurities caught on the screen by hand. Exposure to hazards and unsanitary working conditions. In particular, the inside of the split sewer pipe, into which manure flows directly without a septic tank, is full of harmful gases such as hydrogen sulfide and methane, or the oxygen concentration for breathing is absolutely insufficient, which can cause a suffocation disaster. Prepare for a harmful gas disaster in summer There is such a hassle as having to wear a safety gear.

In addition, a sewage pipe monitoring system has been proposed in this regard, but it is also impossible to check the exact inside of the sewer pipe. It depends on how to do it, but there is a disadvantage that a lot of time and money are invested.

Therefore, in order to protect managers from unsanitary working environments and safety accidents, prevent frequent breakdowns of relay pumps (P) and consequent leakage of untreated sewage, and eventually operate sewage treatment facilities (C) stably, It is necessary to remove the impurity before it enters the relay pumping station (PS), and a method for removing the impurity is also required so that the manager can work hygienically in a safer situation.

Unlike the coupling device of the present invention, which can be simply installed inside the manhole of the treatment area with a small-scale non-powered manual type, the prior patent literature and practical literature presented below are of a scale equipped with power installed in a medium-to-large relay pumping station or sewage treatment facility. It is a large automatic equipment.

Hereinafter, the apparatus of the present invention will be described in more detail with reference to the accompanying drawings. The following description is intended to aid understanding and practice of the present invention, but is not intended to limit the present invention thereto.

Those skilled in the art to which the present invention pertains will understand that various variations, modifications, or changes may be made within the spirit of the present invention described in the claims below.

2 to 3a are standard structural views of the manhole (MH) in which the sewage impurity collection/lifting coupling device of the present invention is installed. FIG. 2 is a longitudinal cross-sectional view and a cross-sectional view, and FIG. 3 is a floor detail and plan view. Hereinafter, the structure and role of the manhole (MH), which is actually installed by combining the sewage impurities collection and lifting structure of the present invention, will be described through FIGS. 2 and 3A. Prior to that, the reason why the coupling device of the present invention is installed in the manhole (MH) before the relay pumping station (PS) is that in general, the relay pumping station (PS) has a deeper depth than the manhole (MH) and two pumps (P ) is installed, the inside is complicated, the inlet pipe is at the bottom, and a constant pump operating level is formed, so it is difficult to install or maintain the device of the present invention.

As described above, the manhole (MH) is installed according to the sewage design standards of the Ministry of Environment for maintenance of the pipe (PL) to clean foreign substances such as impurities or observe the presence or absence of abnormalities inside the pipe (PL) to improve the sewage flow. As a facility that plays a smooth role, a sewage inlet pipe (PL) is formed on one side as shown in FIGS. 2 to 3a, and an outflow pipe (RP) flowing down to the downstream and relay pumping station (PS) is formed on the other side . A manhole cover D and a manhole hole DH are formed on the upper surface facing the ground, and a buried ladder SD is installed on the manhole body 10 on the outer side of the manhole hole DH. In addition, on the bottom surface, an invert (VT) for maintaining the waterway shape of the inlet pipe (PL) and the outlet pipe (RP) so that sewage flows smoothly, and a footing part (BT) to help the manager's work are installed. In general, the sewage design standard standard of the Ministry of Environment of No. 1 manhole, which is most commonly applied to divided sewage pipes and modeled in the device of the present invention, is that the direct diameter of the manhole cover (D) is 648mm and the diameter of the manhole hole (DH) is 600mm , the inner diameter of the manhole is circular with a diameter of 900 mm.

The detailed structure and specifications of the manhole (MH) as described above are the impurities collection screen 100 and the guide rail 200 for lifting the impurities collection screen 100 in implementing the sewage impurities collection/lifting coupling device of the present invention. It is an important factor in determining the shape and size, installation location and fixing method of

As described above, the sewage contaminant collection/lifting coupling device of the present invention is a guide that pulls the impurity collection screen 100 for collecting impurities into one place and the impurity collection screen 100 in which impurities are collected from outside the manhole through the manhole hole (DH). It is completed by combining the rail 200.

Figure 4 is a live-action structure diagram in which different structures and functions of sewage collection and lifting in the present invention are integrally combined. When installed and managed in this way, the manager takes the risk to reduce the burden of going in and out of the deep manhole (MH) It is possible to prevent frequent failures of the subsequent intermediate pump (P) in advance, and finally stabilize the sewage treatment facility (C). Hereinafter, components and installation structures capable of implementing the sewage contaminant collection/lifting combination device of the present invention will be described through several drawings shown.

5 is a detailed structural diagram of the impurities collection screen 100, which is one of the three components of the non-powered collection/lifting coupling device for removing sewage impurities of the present invention. As shown in FIG. 5, the impurities collection screen 100 has a generally hexahedral appearance and is composed of a front screen 101, a rear screen 102, and a side screen 103 toward the downstream with respect to the sewage inlet pipe (PL). In addition, the bottom screen 104 is semicircular in order to completely collect impurities, so that it is closely seated on the invert (VT) of the manhole bottom, and is a circular open type so that impurities can flow into the screen by combining with the front screen 101. There is a through hole. On the other hand, the lift hooks 120a, 120b and the lifting line 130 are used as means for lifting the heavy impurity collection screen 100 containing the impurities outside the manhole without the manager entering the manhole or re-seating it inside the manhole. is formed The lifting rings 120a and 120b surround the two lifting shafts 210a and 210b of the guide rail 200 so that they can move up and down along the guide rail 200 and have one side pierced so as not to be separated. A rear screen 102 is attached to frames 110a and 110b, respectively. The lifting line 130 is attached to the rear screen 102 of the impurities collection screen 100, the top of the frames 110a and 110b, and the three points in the center of the top of the front screen 101, It is desirable that the center of gravity be gathered.

6 is a development view of the above-described impurity collection screen 100, the front screen 101 is formed with a semicircular bottom screen 104 and a through hole as large as the diameter of the manhole inlet pipe PL, so that the invert of the manhole bottom ( It is a structure that is closely seated on the VT) and can collect impurities. The above-described side screens 103a and 103b and the rear screen 102 have a screen structure to prevent impurities from escaping, and the upper portion of the impurities collection screen 100 is opened to shake off impurities caught on the screen. In the impurities collection screen 100, the shape of the net is preferably a lattice shape, and the interval can be varied according to the type and size of impurities mixed in the sewage. The material of the contaminant collection screen 100 is preferably a material that can withstand corrosive gases (hydrogen sulfide, sulfide oxide, nitrogen oxide, hydrogen chloride, etc.), and it is preferable that the outer shape is made of a round bar to easily shake off the contaminants caught on the screen. desirable. In addition, it is preferable to make the thickness of the surface of the hexahedral screen connected and the upper edge where the screen is not formed larger than the thickness of the net in consideration of the weight of the collected impurities.

7 or 7a is a lifting ring for combining the above-described impurities collection screen 100 and the guide rail 200, which are three components of the non-powered collection and lifting coupling device for removing sewage impurities of the present invention, to operate integrally ( 120a, 120b) and the shape of the lifting line 130 that pulls the impurities collection screen 100 out of the manhole. As described above, the lifting rings 120a and 120b are connected to surround the circular guide rail 200 to prevent the impurity collection screen 100 from escaping. The frame (110a, 110b) may be bound by welding to the upper half of the middle, or may be bound to four places in a ring shape at the upper and lower ends of the frame (110a, 110b).

The lifting line 130 that pulls the weight of the impurities collection screen 100 itself and the weight including impurities out of the manhole is preferably a chain or wire rope made of corrosion-resistant material, and a lifting line hanger on the wall of the manhole hole (DH) 250) is installed, and the lifting line 130 should be hung while the impurity collecting screen 100 is seated on the invert (VT) and collects the impurity.

Figure 8 is a detailed view of the guide rail 200, which is another component of the non-powered collection and lifting coupling device for removing sewage impurities of the present invention. The guide rail 200 of the present invention not only assists the upward movement of the impurities collection screen 100 by means of a pair of lifting shafts 210a and 210b, but also allows the impurities collection screen 100 to be accurately placed on the invert (VT) of the manhole bottom. It induces close contact and also serves to prevent the impurity collection screen 100 from being pushed by the flow of sewage and leaving its position toward the outlet pipe (RP) of the manhole due to the resistance of the collected impurities. Therefore, together with the selection of the standard and material of the guide rail 200, the method of fixing the upper and lower parts in close contact with the inside of the manhole is an important factor.

As shown in FIG. 8, the guide rail 200 is composed of a pair of left and right lifting shafts 210a and 210b so that the impurity collecting screen 100 can be stably moved up and down and detached, and the impurity collecting screen 100 is lifted With the help of the lifting hooks 120a and 120b and the lifting line 130 attached between the shafts 210a and 210b, it moves up and down and is seated on the invert (VT) of the manhole bottom or taken out of the manhole. Therefore, the guide rail 200 has a fixed interval considering the depth of the manhole to prevent the impurity collection screen 100 from escaping because the left and right lifting shafts 210a and 210b are deformed or the interval narrows or widens inward or outward. It is preferable to install braces 240. The brace 240 of the present invention is attached to the lifting shafts 210a and 210b of the guide rail 200 and is attached to the outside of the lifting shafts 210a and 210b so as not to interfere with the movement of the impurities collection screen 100 moving up and down. It should be fixed as shown in FIG. 11, and it is preferable to complete the brace 240 together with the guide rail 200 by welding a round bar made of a material that can withstand corrosive gases such as hydrogen sulfide and methane.

In addition, the anchor bolt 221, which can be fixed so that the guide rail 200 and the lifting line 130 are not easily dismantled, is rotationally coupled to the concrete wall to support the lifting line 130 so that it does not fall.

The stainless steel plate 222 to which the guide rail 200 can be coupled so as not to fall easily is combined with the anchor bolt 221 and coupled with the upper fixing means 220a and 220b provided on the upper side of the guide rail 200 it is desirable to be

The guide rail 200 of the present invention formed as shown in FIG. 8 is fixed to the top and bottom of the manhole body 10 as shown in FIGS. 9 to 10a. First, the guide rail 200 fixes the upper part of the manhole body 10 to the inside of the manhole hole (DH) for manager access at the top of the manhole body 10 with the fastening means as shown in FIG. 9 or 9a, and the buried ladder (SD) ) is installed, the upper fixing means (220a, 220b) is fixed to the opposite central wall surface, and the guide rail 200 is provided with a welding part 224 completed by welding with the lifting shafts (210a, 210b), so that the front screen ( 101), the side screen 103, and the bottom screen 104 are not easily dismantled.

The reason why the upper fixing is formed in the center of the manhole hole (DH) is that there is a landfill ladder (SD) on the outer surface of the manhole hole (DH), so it cannot and should not be installed. On the other hand, the guide rail 200 and the lower part of the lifting shafts 210a and 210b are fixed by the same fastening means as shown in Figs. 10 and 10a, and It is completed with lower fixing means (230a, 230b) to the foot portion (BT) at the boundary. In this way, the impurities collection screen 100 is closely seated on the invert VT, so that impurities mixed in the sewage are smoothly collected. A lifting line hanger 250 is installed between the lower fixing means 230a and 230b provided on the upper part of the lifting shafts 210a and 210b of the guide rail 200, and the impurity collection screen 100 is seated on the invert (VT). After that, the lifting line 130 is hung on the lifting line hanger 250 until it is lifted to prevent the lifting line 130 from falling to the bottom of the manhole.

The communication unit 23 capable of transmitting and receiving the result stored in the server unit 22 is characterized in that it can transmit and receive data to the manager.

The step of transmitting the situation based on the above configuration (S10) is a step of transmitting the situation generated in the impurity collection screen 100 to the smart device 20, which is an output device that the manager can check.

The step (S20) in which the manager can check through the above step (S10) is that the manager can know the impurity collected from the impurity matter collection screen 100 put into the manhole and the collection progress level through the smart device 20, and the collection progress level This is the stage where you can check the specifics in the situation.
