Various public infrastructure construction supporting urban life falls within the scope of municipal engineering. Water supply and drainage generally refers to urban water supply systems and drainage systems.

[0003] At present, a filter is needed for filtration in the sewage treatment process in the drainage system. However, if the filter is not cleaned in time, it will cause debris to clog the mesh after long-term use, which will affect the filtering effect. When it needs to be disassembled and cleaned, it will be very troublesome. Based on this, we propose an improved water supply and drainage coarse filtration device. Utility Model Content

[0004] The main purpose of the utility model is to provide a water supply and drainage coarse filtering device, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] As a further solution of the utility model, the plurality of drive plates are rotatably arranged in the guide shell, and the plurality of drive plates are made of a mesh structure, and the mesh diameter is not greater than 5 mm.

[0008] As a further solution of the utility model, the other end of the mounting frame is rotatably sleeved on the outer wall of the water pipe, and the lower end of the cleaning scraper is slidably arranged to fit the surface of the cylindrical filter screen.

[0009] As a further solution of the utility model, the driven shaft and the driving shaft are respectively fixedly sleeved with a pulley 1 and a pulley 2 on the outer walls near the same end, and belts are sleeved on the outer walls of the pulley 1 and the pulley 2.

[0010] As a further solution of the utility model, the power chamber is arranged at one side of the sewage input chamber, and the sludge tank is arranged at one side of the rear end of the sewage input chamber.

[0011] As a further solution of the utility model, the guide shell is arranged in the power chamber, the lower end of the drain pipe passes through the power chamber, and the front end of the power chamber is rotatably connected with a sealing door.

[0012] As a further solution of the utility model, a sealing door 2 is rotatably connected to the rear side of the sewage input chamber near the bottom plate. The sealing door 2 is arranged on one side above the sludge tank. A sewage pipe is fixedly sleeved on one side of the sludge tank.

[0013] The beneficial effects of the utility model are as follows:

[0014] The filtered water entering through the water guide pipe is guided by setting a guide housing, so that the gravity of the water flow drives the driving plate to rotate, and then the second pulley is driven to rotate through the driving shaft, and then the first pulley is driven to rotate through the belt, and then the driven shaft is driven to rotate, and then the mounting frame is driven to rotate around the surface of the cylindrical filter screen, so that the surface of the filter screen can be cleaned by the cleaning scraper, the adhesion of debris is reduced, and the service life of the filter screen is extended;

[0015] By adopting a mesh-structured driving plate structure, when too much sludge accumulates in the sewage input into the room, resulting in increased rotation resistance of the mounting frame, which in turn causes the driving plate to rotate slowly or unable to rotate in the opposite direction, the water flow filtered by the cylindrical filter can still flow through the mesh holes on the driving plate to be discharged into the drain pipe, thus avoiding the impact of the mounting frame on the water output when it is slow or unable to rotate, which is practical.

[0022] like Figure 1-4 As shown, a water supply and drainage coarse filtration device includes a treatment box 1, which includes a sewage input chamber 2, a power chamber 3 and a sludge tank 16. A driven shaft 4 is rotatably sleeved on one side of the sewage input chamber 2, a cylindrical filter screen 5 is rotatably sleeved on one side of the driven shaft 4, a water guide pipe 8 is fixedly sleeved on one side of the cylindrical filter screen 5, the other end of the water guide pipe 8 passes through the side plate of the sewage input chamber 2 and is fixedly connected to a guide shell 9, a driving shaft 10 is rotatably connected to the middle part of the guide shell 9, a plurality of driving plates 11 are fixedly sleeved on the outer wall of the driving shaft 10, a drainage pipe 12 is fixedly sleeved on the middle part of the lower end of the guide shell 9, a mounting frame 6 is fixedly sleeved on the outer wall of the driven shaft 4, and a cleaning scraper 7 is fixedly connected to the lower end surface of the top plate of the mounting frame 6.

[0023] In this embodiment, multiple drive plates 11 are rotatably arranged in the guide shell 9. The multiple drive plates 11 are made of a mesh structure with a mesh diameter of no more than 5 mm. When the rotation resistance of the drive shaft 10 increases to a certain extent, the water filtered by the cylindrical filter 5 can still flow into the drain pipe 12 through the mesh of the drive plate 11 and be discharged.

[0024] In this embodiment, the other end of the mounting frame 6 is rotatably sleeved on the outer wall of the water pipe 8, and the lower end of the cleaning scraper 7 is slidably arranged to fit the surface of the cylindrical filter screen 5, so that the cleaning scraper 7 can scrape and clean the debris on the surface of the cylindrical filter screen 5.

[0025] In this embodiment, a pulley 13 and a pulley 2 14 are fixedly sleeved on the outer walls of the driven shaft 4 and the driving shaft 10 near the same end, and a belt 15 is sleeved on the outer walls of the pulley 13 and the pulley 2 14. The diameter of the pulley 2 14 is larger than that of the pulley 1 13. The pulley 2 14 drives the pulley 1 13 to accelerate its rotation through the belt 15.

[0026] In this embodiment, the power chamber 3 is arranged on one side of the sewage input chamber 2, the sludge tank 16 is arranged on one side of the rear end of the sewage input chamber 2, the guide shell 9 is arranged in the power chamber 3, the lower end of the drain pipe 12 passes through the power chamber 3, and the front end of the power chamber 3 is rotatably connected with a sealing door 1.

[0027] In this embodiment, a sealing door 2 is rotatably connected to the rear side of the sewage input chamber 2 near the bottom plate, so that the sludge in the sewage input chamber 2 can be discharged into the sludge tank 16 after the sealing door 2 is opened. The sealing door 2 is arranged at a position on one side above the sludge tank 16, and a sewage pipe 17 is fixedly connected to one side of the sludge tank 16 for discharging the sludge in the sludge tank 16 for treatment.

[0028] It should be noted that the utility model is a coarse filtering device for water supply and drainage. When in use, the connecting pipe at the upper end of the sewage input chamber 2 is connected to the sewage discharge pipe, and the drain pipe 12 is connected to the pipe of the sewage subsequent treatment equipment, and then the sewage is discharged into the sewage input chamber 2, and filtered through the cylindrical filter screen 5. The filtered water flows through the water guide pipe 8 into the guide shell 9. Under the action of the gravity of the water flow, it will push the driving plate 11 to rotate, and then flow out from the drain pipe 12. During the rotation process, the driving plate 11 will drive the pulley 2 14 to rotate through the driving shaft 10, and then drive the pulley 1 13 to rotate through the belt 15, and then drive the mounting frame 6 to rotate around the cylindrical filter screen 5 through the driven shaft 4, and then scrape the debris on the surface of the filter screen through the cleaning scraper 7 to avoid clogging the mesh. During the later cleaning, the sewage discharge pipe valve is closed, the sealing door on the sewage input chamber 2 is opened, the sludge is discharged into the sludge tank 16, and then discharged through the sewage pipe 17 for treatment.
