[0026] like Figures 1-4 As shown, this utility model provides a technical solution: a water supply and drainage filtration device for water conservancy projects, including an inlet pipe 1 and an outlet pipe 2;

[0027] The filter structure 3 is disposed between the inlet pipe 1 and the outlet pipe 2 and is used to filter the drainage of the water conservancy project.

[0028] The filter structure 3 includes a filter box 301. One end of the filter box 301 has a filter chamber 304, and the two ends of the filter chamber 304 are respectively provided with an inlet connector 302 and an outlet connector 303. The inlet connector 302 is connected to the inlet pipe 1, and the outlet connector 303 is connected to the outlet connector 303.

[0029] The inner walls at both ends of the filter chamber 304 are provided with mounting plates 305 and fixing plates 306, and semi-circular through holes are opened on one side of the outer wall of the mounting plates 305 and fixing plates 306.

[0030] The inner wall of the filter chamber 304 is provided with mounting holes at equal intervals. The mounting holes are provided with a filter plate 307, an adsorption plate 308 and a microporous filter screen 309. A rotating shaft 310 is rotatably provided at the center of one side of the mounting plate 305.

[0031] The other end of the rotating shaft 310 passes through the inner wall of the microporous filter 309, the adsorption plate 308 and the filter plate 307, and is rotatably connected to the center of the mounting plate 305. A driven bevel gear 312 is fixedly connected to the outer wall of the rotating shaft 310.

[0032] Multiple fixing rings are fixedly connected to the outer wall of the rotating shaft 310. The multiple fixing rings are located on the outer outer walls of the filter plate 307, adsorption plate 308 and microporous filter 309 respectively. Cleaning heads 311 are equidistantly arranged on the outer walls of the fixing rings. The cleaning heads 311 are in contact with the outer sides of the filter plate 307, adsorption plate 308 and microporous filter 309.

[0033] A connecting rod is rotatably mounted on the inner wall of the top of the filter box 301. A driving bevel gear 313 is installed at the other end of the connecting rod. The driving bevel gear 313 meshes with the driven bevel gear 312. A motor 314 is installed at the top of the filter box 301. The output end of the motor 314 is connected to the connecting rod.

[0034] Connecting blocks are equidistantly arranged on the inner wall of the filter chamber 304. A protective cover 315 is provided at the other end of each connecting block. The protective cover 315 protects the driving bevel gear 313 and the driven bevel gear 312. It should be clear that in this embodiment, the inlet pipe 1 is connected to the drainage pipe at the construction site. The drainage pipe discharges water into the inlet pipe 1, which in turn is connected to the inlet connector 302 in the filter structure 3. Therefore, the drainage can be filtered. The inlet connector 302 and the inlet pipe 1 are threaded together. In this application, the inlet connector 302 and the inlet pipe 1 can be connected by a snap-fit ​​(not shown). As mentioned above, mounting plates 305 and fixing plates 306 are provided on the inner walls at both ends of the filter chamber 304. The mounting plate 305 is located at the water inlet end of the filter chamber 304, and the fixing plate 306 is located at the water outlet end of the filter chamber 304. Figure 3As shown, a semi-circular through hole is provided on one side of the mounting plate 305 and the fixing plate 306. The semi-circular through hole is to facilitate the discharge of filtered water through the outlet pipe 2. A rotating shaft 310 is rotatably arranged between the mounting plate 305 and the fixing plate 306. A driven bevel gear 312 is fixedly connected to the outer wall of the rotating shaft 310. A connecting rod is rotatably arranged on the inner wall of the top of the filter box 301. The other end of the connecting rod is equipped with a driving bevel gear 313. The power source of the connecting rod is a motor 314, which is connected to the power supply of an external device. As mentioned above, the driving bevel gear 313 is meshed with the driven bevel gear 312. Therefore, the rotation of the driving bevel gear 313 can drive the driven bevel gear 312 to rotate. Figure 3 and Figure 4 As shown, it should also be clear that the rotating shaft 310 penetrates the central inner wall of the filter plate 307, the adsorption plate 308, and the microporous filter screen 309. When the rotating shaft 310 rotates, the filter plate 307, the adsorption plate 308, and the microporous filter screen 309 will not rotate with the rotating shaft 310. In order to facilitate the cleaning of impurities adsorbed on the filter plate 307, the adsorption plate 308, and the microporous filter screen 309, a fixing ring is provided on the outer wall of the rotating shaft 310. Cleaning heads 311 are evenly distributed on the outer wall of the fixing ring. The cleaning heads 311 can clean the filter plate 307, the adsorption plate 308, and the microporous filter screen 309.

[0035] like Figure 3 As shown, to protect the driving bevel gear 313 and the driven bevel gear 312, a protective cover 315 is provided on the filter chamber 304. The driving bevel gear 313 and the driven bevel gear 312 are located on the inner wall of the protective cover 315, thereby protecting the driving bevel gear 313 and the driven bevel gear 312 and preventing corrosion of the gears caused by water supply and drainage, which would affect their operation. Simultaneously, to fix the protective cover 315, a connecting block is provided on the outer wall of the protective cover 315. The connecting block is connected to the inner wall of the filter chamber 304. In this application, the connection can be made by bolts, or the protective cover 315 can be directly connected to the fixing plate 306. A gap is also reserved between the connecting block and the filter chamber 304 to allow drainage flow. It should also be noted that in this application, the inner wall of the filter box 301 is provided with an inspection door for maintenance or replacement of the filter chamber 304. Since the inspection door is prior art, it is not shown in this application.

[0036] The working principle of this utility model is as follows:

[0037] First, connect the inlet pipe 1 to the water supply and drainage pipe. The water supply and drainage pipe will then deliver water into the filter chamber 304 inside the filter box 301 through the inlet pipe 1. The filter plate 307 installed in the filter chamber 304 can filter impurities in the water supply and drainage. The preliminarily filtered drainage will then pass through the adsorption plate 308 to adsorb microorganisms or other impurities in the drainage again, and then pass through the microporous filter screen 309 for further filtration. The filtered drainage will then be discharged through the outlet pipe 2. After long-term use, impurities will adhere to the outer walls of both sides of the filter plate 307, adsorption plate 308, and microporous filter screen 309. Then, the motor 314 will drive... The connecting rod rotates, and the other end of the connecting rod is equipped with a driving bevel gear 313, which drives the driven bevel gear 312 to rotate. Since the driven bevel gear 312 is installed on the outer wall of the rotating shaft 310, it can drive the rotating shaft 310 to rotate. A fixing ring is installed on the outer wall of the rotating shaft 310, and cleaning heads 311 are evenly distributed on the outer wall of the fixing ring. Therefore, when the rotating shaft 310 rotates, it can drive the cleaning heads 311 to rotate. The cleaning heads 311 are in contact with the surfaces of the filter plate 307, the adsorption plate 308, and the microporous filter screen 309, so they can be cleaned.

[0038] In summary: A water supply and drainage filtration device for water conservancy projects includes an inlet pipe 1 and an outlet pipe 2;

[0039] The filter structure 3 is disposed between the inlet pipe 1 and the outlet pipe 2 and is used to filter the drainage of the water conservancy project. The filter structure 3 includes a filter box 301, a filter chamber 304 is provided at one end of the filter box 301, and an inlet connector 302 and an outlet connector 303 are respectively provided at both ends of the filter chamber 304. The inlet connector 302 is connected to the inlet pipe 1, and the outlet connector 303 is connected to the outlet pipe 1. With the filter structure 3, an adsorption plate 308, a filter plate 307, and a microporous filter screen 309 are installed in the filter chamber 304 to filter water supply and drainage. The cleaning head 311 can periodically clean the adsorption plate 308, the filter plate 307, and the microporous filter screen 309 to prevent the filter media from being blocked by impurities, maintain filtration efficiency, ensure smooth water flow, reduce the accumulation of dirt and deposits, reduce the risk of equipment aging and damage, and extend the service life of the equipment. The cleaning head 311 can prevent water flow interruption or incomplete filtration caused by the blockage of the filter plate 307 or the filter screen, ensuring the long-term stable operation of the water supply and drainage system.
