The two water conveying mechanisms 5 are fixedly connected to the same side on their adjacent sides, which can collect and transport the cleaned impurities. The inner cavities of the two sets of limiting grooves 21 are slidably connected to the drive mechanism 12, which can drive the transmission mechanism 6 to rotate.

[0026] To achieve the purpose of collecting and transporting the swept debris, see [reference needed]. Figure 2 The material conveying mechanism 11 includes a material conveying shell 111. A water injection pipe 112 is fixedly connected to the middle of the upper part of the outer surface of the material conveying shell 111, and a stop plug 113 is slidably connected to the lower part of the inner cavity of the material conveying shell 111.

[0027] During the cleaning process, impurities will be swept towards the material conveying shell 111 by several sets of cleaning brushes 82 until they finally fall downward into the inner cavity of the material conveying shell 111 through the inner cavity of the through groove 52.

[0028] To achieve the purpose of transporting the injected wastewater, see [reference needed]. Figure 3 The water conveying mechanism 5 includes a water conveying shell 51.

A water collection shell 102 is fixedly connected to the bottom wall of the inner cavity of the support platform 101, which can collect the filtered water and discharge it through several drain pipes 13. The upper part of the outer surface of the support platform 101 is fixedly connected to the lower part of the outer surface of the filter screen 9.

[0030] To achieve the goal of rotating the sweeping mechanism 8, please refer to... Figure 4 The transmission mechanism 6 includes a rectangular frame 61. A rack 62 is fixedly connected to the bottom wall of the inner cavity of the rectangular frame 61, which enables the gear 63 to move along the inner cavity of the rectangular frame 61.

The gear 63 is slidably connected to the inner wall of the rectangular frame 61, and the outer surface of the rectangular frame 61 is fixedly connected to the front of the water supply shell 51.

[0031] To guide the movement of the cleaning mechanism 8, see [reference needed]. Figure 4 The guiding mechanism 7 includes a rectangular frame 71, and a sliding block 72 is slidably connected to the inner cavity of the rectangular frame 71, which can guide the movement of the rotating column 81. The outer surface of the rectangular frame 71 is fixedly connected to the rear of the water supply shell 51.

[0032] To clean the impurities remaining on the outer surface of filter screen 9, please refer to... Figure 4 The cleaning mechanism 8 includes a rotating column 81. Several sets of cleaning brushes 82 are fixedly connected to the outer surface of the rotating column 81 at intervals. The brushes 82 can clean the impurities remaining on the upper part of the outer surface of the filter screen 9 by following the movement of the gear 63. The front end of the outer surface of the rotating column 81 is fixedly connected to the middle of the rear end of the outer surface of the gear 63, and the rear end of the outer surface of the rotating column 81 is rotatably connected to the middle of the front end of the outer surface of the sliding block 72.

[0033] Driven by the motor 122, the gear 63 meshes with the rack 62 and moves along the inner cavity of the rectangular frame 61. At the same time, the gear 63 will drive the rotating column 81 to rotate, and the rotating cleaning brushes 82 will clean the impurities remaining on the outer surface of the filter screen 9 from top to bottom.

[0034] To achieve the purpose of driving the transmission mechanism 6 to rotate, refer to... Figure 5 The drive mechanism 12 includes a protective housing 121. A motor 122 is fixedly connected to the inner cavity of the protective housing 121. Connecting plates 123 are symmetrically fixedly connected to the upper and lower parts of the outer surface of the protective housing 121. T-shaped plates 124 are fixedly connected to the rear ends of the outer surfaces of the two connecting plates 123, which can enable the motor 122 to move along the inner cavity of the set limiting groove 21. The two T-shaped plates 124 and the inner cavities of the two corresponding limiting grooves 21 are slidably connected. The output end of the motor 122 is fixedly connected to the middle of the front end of the outer surface of the gear 63.

[0035] It should be noted that the specific installation method, circuit connection method and control method of the motor 122 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0036] The working principle of this utility model is as follows: First, wastewater to be filtered can be injected into the inner cavity of two water conveying shells 51 through two inlet pipes 4, allowing it to undergo preliminary filtration through two filter screens 9 fixed on the lower part of the outer surface of the water conveying shells 51. At this time, the filtered water will be stored in the inner cavity of the corresponding water collection shells 102 along the inner cavity of the two support platforms 101, and then discharged to the outside through two sets of several drain pipes 13 for the next step of filtration. When there are too many impurities attached to the outer surface of the two filter screens 9 and they need to be cleaned, the controller 3 controls two motors 122 to start driving. The driving of the motors 122 causes the gear 63 to mesh with the rack 62 and move along the inner cavity of the rectangular frame 61. The gear 63 will drive the rotating column 81 to rotate, and the rotating column 81 will drive the sliding block 72 to move. The inner cavity of rectangular frame 71 slides from top to bottom. Several sets of cleaning brushes 82, which are rotating, will clean the impurities remaining on the outer surface of the filter screen 9. At the same time, the protective sleeve 121 will follow the movement of gear 63 in the inner cavity of rectangular frame 61, causing the protective sleeve 121 to slide along the inner cavity of the corresponding limiting groove 21. This allows several sets of cleaning brushes 82 to clean the upper part of the corresponding outer surface of the filter screen 9. The impurities cleaned from top to bottom will follow several sets of cleaning brushes 82 into the inner cavity of the support platform 101. When it is necessary to clean the impurities collected in the inner cavity of the support platform 101, an appropriate amount of water can be injected into the inner cavity of the conveying shell 111 through the water injection pipe 112. At this time, the stop plug 113 is pulled out, and the injected water is used to clean the impurities collected in the lower part of the inner cavity of the conveying shell 111 along the inner wall of the conveying shell 111.
