The dredge strips 10 and the mounting strips 12 are arranged at the same height. There is a gap between two adjacent dredge strips 10. The dredge column 9 is welded to the top of the dredge strip 10. The dredge column 9 is used to embed the filter hole 7. The number and position of the dredge column 9 and the filter hole 7 correspond one to one. The scraping assembly includes a hydraulic rod 2 13 and a scraper 14. The hydraulic rod 2 13 is arranged horizontally and is screwed to the inner wall of the wastewater filter 1. The hydraulic rod 2 13 is driven by a motor 2. The movable end of the hydraulic rod 2 13 passes through the mounting plate 2 5 and is welded to the scraper 14. The mounting plate 2 5 is provided with a through hole 2 to accommodate the movement of the movable end of the hydraulic rod 2 13. The hydraulic rod 2 13 and the scraper 1 4 are all set close to the mounting plate 2 5, the scraper 14 and the top surface of the filter 6 are in contact with each other, the top of the wastewater filter 1 is provided with a through slot 15, and the through slot 15 is connected to the inside of the wastewater filter 1, the slot width of the through slot 15 is equal to the width of the collection frame 8, the top of the wastewater filter 1 is detachably connected to a cover plate 16, the width of the cover plate 16 is greater than the slot width of the through slot 15, the bottom of the cover plate 16 is in contact with the outer top surface of the wastewater filter 1, and a pull rope 17 is bonded between the bottom of the cover plate 16 and the top of the collection frame 8. The number of the pull ropes 17 is two, and a panel 18 for snapping into the bottom of the collection frame 8 is welded on the side of the mounting plate 1 4 away from the filter 6. The cross-section of the panel 18 is L-shaped, and there is a gap between the panel 18 and the inner wall of the wastewater filter 1.

[0019] The waste water is poured downwards into the waste water filter 1 through the water inlet 2, and the waste water will not be poured into the collection frame 8. During the waste water flowing downwards, the impurities in the waste water are filtered through the filter mesh 6, and the filtered impurities will adhere to the top surface of the filter mesh 6. After the filtration, the waste water continues to flow downwards through the filter holes 7. During the waste water flowing downwards, it will pass through multiple gaps formed by multiple dredging strips 10 until the waste water flows to the bottom surface of the waste water filter 1, and then the filtered waste water is discharged through the outlet pipe 3 for collection and treatment. After the waste water is discharged from the outlet pipe 3 after filtration, the movable end of the hydraulic rod 11 can be driven upwards by the motor 1, and the movable end of the hydraulic rod 11 moves in the through hole 1 on the filter mesh 6, and the hydraulic rod 11 moves to During the upward movement, the mounting bar 12, the dredging bar 10 and the dredging column 9 are respectively driven to move upward until the top surfaces of the dredging bar 10 and the mounting bar 12 are in conflict with the bottom surface of the filter screen 6. At this time, the dredging column 9 is embedded in the filter hole 7 to dredge and clean the impurities blocking the filter hole 7, and clean the dredged impurities to the top surface of the filter screen 6 to reduce the situation where impurities block the filter hole 7. When the dredging column 9 is embedded in the filter hole 7, the dredging column 9 does not contact the scraper 14. After the dredging column 9 dredges the filter hole 7, the movable end of the hydraulic rod 11 is moved downward. When the hydraulic rod 11 moves downward, the mounting bar 12, the dredging bar 10 and the dredging column 9 are respectively driven to move downward until the mounting bar 12, the dredging bar 10 and the dredging column 9 are all located at the bottom of the filter screen 6.

[0020] After the mounting strip 12, the dredging strip 10 and the dredging column 9 are all located at the bottom of the filter 6, the movable end of the hydraulic rod 2 13 is driven by the motor 2 to move in the horizontal direction. The movable end of the hydraulic rod 2 13 moves in the through-hole 2 on the mounting plate 2 5. When the hydraulic rod 2 13 moves in the horizontal direction, it drives the scraper 14 to move in the direction close to the collection frame 8. At this time, the scraper 14 scrapes the impurities attached to the top surface of the filter 6. When the scraper 14 moves, it does not contact the hydraulic rod 11, so that the scraper 14 first leaves the filter 6 with the impurities, and then the scraper 14 contacts the top surface of the mounting plate 4, and finally pushes the impurities into the collection frame 8 for centralized collection. After the impurities are pushed into the collection frame 8, the movable end of the hydraulic rod 2 13 drives the scraper 14 to move in the direction close to the mounting plate 2 5. The filter 6 can be cyclically cleaned by using the dredging component and the scraping component in succession.

[0021] When the collecting frame 8 has collected a large amount of impurities, the user pulls up the cover 16 to drive the pull rope 17, the collecting frame 8 and the impurities in the collecting frame 8 to move upward, so that the bottom of the collecting frame 8 is not stuck on the panel 18, until the pull rope 17 and the collecting frame 8 are both out of the through slot 15 and taken out of the wastewater filter 1, and the impurities in the collecting frame 8 are cleaned. Therefore, there is no need to disassemble the filter screen 6 to clean the attached impurities after each use of the wastewater filter 1. It is only necessary to disassemble the collecting frame 8 less times, which reduces the number of times the user cleans the impurities attached to the filter screen 6 and makes cleaning more convenient for the user.

[0022] A fence 19 connected to the water inlet 2 is welded to the inner top wall of the wastewater filter 1. The hydraulic rod 11 is located between the fence 19 and the wastewater filter 1. The top height of the mounting plate 2 5 is greater than the bottom height of the fence 19. In the process of pouring wastewater into the wastewater filter 1 through the water inlet 2, the wastewater is brought into contact with the fence 19 through the fence 19, reducing the damage caused by the wastewater flushing to the hydraulic rod 11. Because the top horizontal height of the mounting plate 2 5 is greater than the bottom horizontal height of the fence 19, wastewater and impurities are prevented from flowing out of the outlet pipe 3 directly from the inner wall of the wastewater filter 1 near the hydraulic rod 2 13.

[0023] A plurality of drain holes are provided on the side wall of the collecting frame 8 away from the mounting plate 4, and there is a gap between the bottom of the mounting plate 4 and the inner bottom surface of the wastewater filter 1. When the impurities are pushed into the collecting frame 8 by the scraper 14, the scraper 14 will push a portion of the wastewater attached to the filter screen 6 into the collecting frame 8. At this time, the drain holes provided on the side wall of the collecting frame 8 away from the mounting plate 4 allow the wastewater remaining in the collecting frame 8 to flow out from the drain holes to the gap between the panel 18 and the inner side wall of the wastewater filter 1 until the wastewater falls on the inner bottom surface of the wastewater filter 1. Because there is a gap between the bottom of the mounting plate 4 and the inner bottom surface of the wastewater filter 1, the wastewater can flow out from the outlet pipe 3 along the inner bottom surface of the wastewater filter 1.

[0024] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
