[0002] Water supply and drainage engineering: engineering for water supply, wastewater discharge and water quality improvement. It is divided into water supply engineering and drainage engineering. In ancient times, water supply and drainage engineering was only used to transport water for cities and discharge precipitation and sewage in cities. In modern times, water supply and drainage engineering is developed to control the spread of infectious diseases such as typhoid, cholera, dysentery and so on in cities and to adapt to the development of industry and cities. Modern water supply and drainage engineering has become the basic facilities for controlling the spread of waterborne infectious diseases and environmental water pollution. It is one of the basic infrastructures for the development of cities and industries, and the main component of municipal engineering.

[0003] At present, when treating water supply and drainage sewage, a sewage pretreatment device is often used to pretreat the water supply and drainage sewage in advance. The existing pretreatment device mainly includes a treatment box, a cover plate and a filter plate fixed therein. The setting of the filter plate realizes the filtration of sewage and the separation of impurities, which is convenient for the recovery of impurities in the later stage. However, sewage often contains impurities with larger particles. When these impurities pass through the filter plate, they may be stuck in the pores of the filter material or adsorbed on the surface of the filter plate. As time goes by, they gradually accumulate and form blockages, resulting in a decrease in filtration efficiency. In addition, the operator needs to disassemble the treatment box and the cover plate, take out the filter plate fixed therein, and then clear it. This method consumes labor and time costs.

[0004] Therefore, it is necessary to provide a new water supply and drainage sewage pretreatment device to solve the above technical problems. Utility Model Content

[0026] In the specific implementation process, Figure 1-Figure 6As shown, a water supply and drainage sewage pretreatment device comprises a treatment box 1, a cover plate 2 detachably connected to the treatment box 1, and a filter plate 11 clamped in the cover plate 2 and the treatment box 1, the cover plate 2 is provided with a mounting groove 5 matching the size of the filter plate 11, both sides of the inner wall of the mounting groove 5 are provided with clamping parts for clamping the filter plate 11, two brushes 13 for dredging the filter plate 11 are rotatably arranged on the inner wall of the lower side of the cover plate 2, the two brushes 13 are respectively located at the left and right ends of the bottom side of the mounting groove 5, and the two ends of the two brushes 13 are respectively rotatably connected to the two sides of the inner wall of the cover plate 2, When the filter plate 11 is to be unblocked, the pretreatment device is closed and the remaining sewage in the treatment box 1 is discharged through the drain port 6, and the clamping parts on both sides are pushed so that the clamping parts do not limit the filter plate 11. At this time, the filter plate 11 can be pulled up and down, and the filter plate 11 moves in the installation groove 5. The brush 13 connected to the bottom side of the cover plate 2 is rotated to contact the filter plate 11. The filter plate 11 can drive the brush 13 to rotate during the movement. The bristles on the brush 13 can be inserted into the mesh of the filter plate 11 to unblock it. After the unblocking is completed, the filter plate 11 is reset, and the clamping parts limit the filter plate 11 at this time.

[0027] The engaging member includes a spring 14, a limit block 15 and a push plate 16. The limit block 15 is slidably arranged in a movable groove 17 opened on one side of the installation groove 5. One end of the limit block 15 is fixedly connected to one end of the spring 14. The end of the spring 14 away from the limit block 15 is fixedly connected to the inner wall of the movable groove 17. The upper end of the limit block 15 is fixedly connected to the bottom end of the push plate 16. The push plate 16 is slidably arranged in a through groove 18 opened on the upper side of the movable groove 17, and the movable groove 17 is connected to the through groove 18. The end of the limit block 15 matches the limit groove 19 opened on the side wall of the filter plate 11. Both sides of the inner wall of the filter plate 11 are provided with slide grooves 20. The two slide grooves 20 are respectively connected to the two limit grooves 19 and have the same width. When the filter plate 11 needs to be dredged, the push plate 16 is pushed, the push plate 16 drives the limit block 15 to run, the spring 14 is compressed, and the limit block 15 slides out of the limit groove 19. At this time, the filter plate 11 can be pulled upward. After the push plate 16 is released, the spring 14 applies a thrust to the limit block 15, so that the limit block 15 is stuck in the slide groove 20 opened on the side wall of the filter plate 11. At this time, the filter plate 11 can be pulled up and down to dredge it with the brush 13. When the filter plate 11 is manually dredged, the filter plate 11 needs to be pulled up and down. At this time, the limit block 15 is stuck in the slide groove 20 opened on the side wall of the filter plate 11 and moves in the slide groove 20 to prevent the filter plate 11 from being pulled out during the dredging process.

[0028] It should be noted that when the filter plate 11 needs to be taken out, the push plate 16 is pushed again, and the push plate 16 drives the limit block 15 to run, and the spring 14 is compressed. At this time, the limit block 15 slides out of the slide groove 20 without limiting the filter plate 11, and the filter plate 11 can be pulled out of the installation groove 5;

[0029] A water inlet 7 and a water outlet 6 are respectively provided on the two side walls of the treatment box 1. The water inlet 7 is connected to a water suction pump 9 through a conduit 8. A valve 10 for regulating water flow is provided on the water outlet 6.

[0030] Two slots 4 matching the two sides of the filter plate 11 are respectively provided on the inner walls on both sides of the processing box body 1. The setting of the slots 4 enables the filter plate 11 to slide stably therein. Both sides of the bottom end of the cover plate 2 and both sides of the upper end of the processing box body 1 are provided with multiple bolt holes 3 for bolting and fixing the two. The cover plate 2 and the processing box body 1 are installed and fixed by bolts, and the structure is stable and reliable, and is not easy to loosen or move.

[0031] A handle 12 is fixedly connected to the upper end of the filter plate 11, so that the operator can pull the filter plate 11 up and down to clear it.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
