[0026] like Figure 1-2 As shown, the present application provides a wastewater treatment device with a filtering structure, including an outer cylinder 1 with an upper opening, a filter cylinder 2 with an upper opening fixed inside the outer cylinder 1, and a cover plate 3 fixedly installed at the upper opening of the outer cylinder 1.

[0027] A partition 21 is fixed to the outer wall of the filter cartridge 2 , and the partition 21 divides the interior of the outer cartridge 1 into two layers, the upper layer being the feed layer 11 and the lower layer being the filter layer 12 .

[0028] A feed pipe 13 is fixed to the upper side of the outer wall of the outer cylinder 1 . The feed pipe 13 is communicated with the inside of the feed layer 11 , and the feed pipe 13 is inclined toward one side of the filter cylinder 2 .

[0029] A water outlet pipe 14 is fixed to the lower side of the outer wall of the outer cylinder 1, and the water outlet pipe 14 is connected to the inside of the filter layer 12. A sewage outlet pipe 15 is fixed to the lower end of the outer cylinder 1, and the sewage outlet pipe 15 is connected to the lower end of the filter cylinder 2.

[0030] The outer wall of the filter cartridge 2 located in the filter layer 12 is provided with a plurality of filter holes 22, a scraper shaft 23 is rotatably connected between the two ends of the filter cartridge 2, and a plurality of scrapers 24 are fixed to the outer wall of the scraper shaft 23. A shaft sleeve 25 is fixed to the upper end of the scraper shaft 23, a drive shaft 31 is rotatably provided on the cover plate 3, the lower end of the drive shaft 31 is adapted to the upper end of the shaft sleeve 25, and a driver 32 is fixed to the upper side of the cover plate 3. In this embodiment, the driver 32 is a motor, and the output shaft of the driver 32 is connected to the upper end of the drive shaft 31.

[0031] A sleeve 4 is rotatably sleeved on the filter cartridge 2 in the feed layer 11 . A plurality of guide plates 41 are evenly distributed circumferentially on the outer wall of the sleeve 4 . The guide plates 41 are inclined. A plurality of blocks 42 are distributed circumferentially on the upper end of the guide plate sleeve 4 .

[0032] A plurality of push plates 26 are fixed to the outside of the shaft sleeve 25, a rotating plate 43 is provided at the upper opening of the filter cartridge 2, a card slot 44 adapted to the card block 42 is provided at the edge of the rotating plate 43, a push slot 45 adapted to the shaft sleeve 25 and the push plate 26 is provided in the middle of the rotating plate 43, and a plurality of feed holes 46 are also provided on the card slot 44.

[0033] The lower end of the driving shaft 31 is adapted to the upper end of the shaft sleeve 25 , so that the driving shaft 31 and the shaft sleeve 25 can be easily separated when the cover plate 3 is disassembled.

[0034] The driver 32 can drive the sleeve 25 and the scraper shaft 23 to rotate via the driving shaft 31 .

[0035] The shaft sleeve 25 can push the push groove 45 through the push plate 26 to drive the rotating plate 43 to rotate. The rotating plate 43 then pushes the clamping block 42 through the clamping groove 44, thereby driving the pipe sleeve 4 and the guide plate 41 to rotate.

[0036] When filtering sewage, the sewage outlet pipe 15 is in a closed state.

[0037] The feed pipe 13 is the sewage inlet. After the sewage enters the feed layer 11, it will flow into the filter cartridge 2 through the opening at the upper end of the filter cartridge 2. Through the rotation of the pipe sleeve 4 and the guide plate 41, since the guide plate 41 is in an inclined state, on the one hand, it is convenient to shovel the impurities at the bottom of the feed layer 11 to prevent the impurities from accumulating in the feed layer 11; on the other hand, it guides the flow of sewage so that the water flow can blow the impurities to the upper side of the feed layer 11 so that the impurities flow into the filter cartridge and prevent the impurities from accumulating too much in the feed layer 11, which makes it difficult to feed sewage.

[0038] After the sewage flows into the filter cartridge 2 , the sewage can flow out through the dry filter holes 22 , and the impurities are filtered out by the filter holes 22 , so that the filtered sewage flows out from the outlet pipe 14 , and the impurities remain in the filter cartridge 2 .

[0039] When the scraper shaft 23 rotates, it can drive the scraper 24 to scrape the inner wall of the filter cartridge 2 to prevent impurities from blocking the filter holes 22.

[0040] When there are many impurities in the filter cartridge 2, the sewage outlet pipe 15 can be opened to allow part of the sewage to flow out with the impurities, thereby preventing the impurities in the filter cartridge 2 from flowing out too much.
