Description

Technical Field

[0001] This utility model relates to the field of pipeline drainage, and in particular to a sewage pipeline filtration device. Background Technology

[0002] Water pipe networks are an important part of urban infrastructure. Municipal sewage is mainly transported to sewage treatment plants through sewage pipes for further treatment. The main sources of municipal sewage are domestic sewage and industrial wastewater. Since sewage often contains many impurities, such as kitchen waste, hair, packaging bags and other debris, it is necessary to separate the impurities in the sewage before discharge. The common treatment method is to add filter screens to the pipes to filter the impurities in the sewage.

[0003] The utility model patent document with authorization announcement number CN212789933U relates to a filtration device for sewage pipelines. The device includes a pipeline with a filtration device inside. The filtration device comprises a grid, a screen, a fixing ring, a placement frame, and a connecting rod. The grid is fixed inside the fixing ring, and the screen is fixed on the placement frame. The placement frame and the fixing ring are connected by the connecting rod. The inner wall of the fixing ring has an insertion hole. The grid includes a grid rod, one end of which passes through the insertion hole. A snap-fit ​​element is provided at the connection point between the grid rod and the insertion hole, located inside the fixing ring. The snap-fit ​​element includes a locking block on the fixing ring with a through hole. One end of the grid rod abuts against the inner wall of the fixing ring through the insertion hole and the through hole. The grid rod and the locking block are connected by threads. This utility model has a simple structure and can quickly remove debris from the grid.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic diagram of a preferred embodiment of a sewage pipeline filtration device provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural schematic. Figure 3 for Figure 1 The diagram shows the structure of the pulverizing mechanism. A sewage pipe filtration device includes a filter shell 1, with support legs 2 bolted to the four corners of the bottom of the filter shell 1. A sewage inlet pipe 3 is connected to a flange on one side of the filter shell 1. A pulverizing mechanism 4 is provided on one side of the top of the sewage inlet pipe 3. The pulverizing mechanism 4 is used to pulverize small debris inside the sewage inlet pipe 3. A water outlet pipe 5 is connected to a flange on one side of the top of the filter shell 1. A cover plate 6 is connected to one side of the top of the filter shell 1 via a hinge. A first handle 7 is bolted to the top of the cover plate 6. Sliding grooves 8 are provided at the four corners of one side of the inner cavity of the filter shell 1. A sludge collection box 9 is provided on one side of the inner cavity of the filter shell 1. A second handle 10 is bolted to both ends of the inner cavity of the sludge collection box 9. A filter plate 11 is bolted to the inner cavity of the filter shell 1.

[0021] In the specific implementation process, such as Figure 1 Figure 2 and Figure 3 As shown, the crushing mechanism 4 includes a drive motor 41. The bottom of the drive motor 41 is bolted to the inlet pipe 3. The output shaft of the drive motor 41 passes through the inner cavity of the inlet pipe 3 and is keyed to a first bevel gear rod 42. A second bevel gear rod 43 is meshed on one side of the first bevel gear rod 42. A cutting blade 44 is bolted to the surface of the second bevel gear rod 43.

[0022] When it is necessary to crush the fine waste inside the sewage inlet pipe 3, the drive motor 41 is started first. The output shaft of the drive motor 41 drives the first bevel gear rod 42 to rotate. At the same time as the first bevel gear rod 42 rotates, it meshes with the second bevel gear rod 43 to rotate. At the same time as the second bevel gear rod 43 rotates, it drives the cutting blade 44 to rotate, thereby effectively crushing the waste inside the sewage inlet pipe 3.

[0023] refer to Figure 3 As shown, both sides of the second bevel gear rod 43 are connected to positioning plates 12 via bearings, and the top of the positioning plates 12 is bolted to the sewage inlet pipe 3.

[0024] The connection between the positioning plate 12 and the sewage inlet pipe 3 serves to fix and support the second bevel gear rod 43.

[0025] refer to Figure 3 As shown, a limiting ring 13 is slidably inserted into the bottom of the drive motor 41, and the bottom of the limiting ring 13 is bolted to the sewage inlet pipe 3;

[0026] The connection between the limiting ring 13 and the sewage inlet pipe 3 serves to limit the rotation of the drive motor 41.

[0027] refer to Figure 2 As shown, sliders 14 are welded and fixed at all four corners of the sludge collection box 9, and the surfaces of the sliders 14 are slidably inserted into the inner cavity of the slide groove 8.

[0028] The connection between slider 14 and slide 8 effectively limits and fixes the sludge collection box 9.

[0029] The working principle of the sewage pipeline filtration device provided by this utility model is as follows:

[0030] In use, first connect the inlet pipe 3 to the sewage pipe and discharge the sewage. If small debris clogs the filter plate 11 during the discharge process, start the drive motor 41. The output shaft of the drive motor 41 drives the first bevel gear rod 42 to rotate. While the first bevel gear rod 42 rotates, it meshes with the second bevel gear rod 43 to rotate. While the second bevel gear rod 43 rotates, it drives the cutting blade 44 to rotate, which can effectively crush the debris inside the inlet pipe 3. The crushed debris will then be discharged into the inner cavity of the sludge collection box 9. The sewage will then be discharged through the filter hole on one side of the sludge collection box 9, and the debris will be intercepted into the inner cavity of the sludge collection box 9. The sewage will then be filtered again through the filter plate 11. Finally, the filtered sewage will be transported to the inner cavity of the outlet pipe 5 and discharged.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
