[0025] The following section will describe in detail the specific settings and functions of its cleaning device 6 and auxiliary components 7.

[0026] In this embodiment: the cleaning device 6 is fixedly installed on the surface of the filter cylinder 5. The cleaning device 6 includes a connecting plate 61 and a connecting arm 64. The connecting plate 61 is slidably connected to the surface of the frame 2. The connecting arm 64 is fixedly connected to the lower surface of the connecting plate 61. An installation ring 68 is fixedly connected to the end of the connecting arm 64 away from the connecting plate 61. The installation ring 68 is a circular metal frame used to fix the connecting ring 66 and the nozzle 67. Its structure has been mechanically optimized to evenly distribute the weight of the nozzle 67 and the pressure during operation. The connecting ring 66 is installed on the outer surface of the installation ring 68. The connecting ring 66 is made of flexible and pressure-resistant rubber material, which has good flexibility and sealing performance and can adapt to the connection requirements of the nozzle 67 at different angles and positions. The nozzle 67 is fixedly connected inside the connecting ring 66. The nozzle 67 is a fan-shaped high-pressure nozzle made of wear-resistant ceramic material. The spray angle and pressure have been professionally designed to effectively wash the sludge on the surface of the filter cylinder 5. The nozzle 67 is fixedly connected inside the installation ring 68. A connecting pipe 63 is fixedly connected to the outer surface of the connecting ring 66.

[0027] Specifically, the connecting pipe 63 is internally fixedly connected to the connecting plate 61, and the upper surface of the connecting plate 61 is fixedly connected to the water inlet pipe 62.

[0028] In this embodiment: by setting the water inlet pipe 62, water can be introduced into the connecting plate 61, reducing the difficulty of water entering the connecting ring 66 through the connecting pipe 63 when the equipment is in use.

[0029] Specifically, a connector 65 is fixedly connected at the connection between the connecting ring 66 and the connecting tube 63. A sliding hole 69 is provided on the upper surface of the frame 2. The connector 65 is provided to facilitate a stable connection between the connecting tube 63 and the connecting ring 66.

[0030] Specifically, the connecting plate 61 is slidably connected inside the sliding hole 69.

[0031] In this embodiment: auxiliary components 7 are fixedly installed on both sides of the frame 2. The auxiliary components 7 include a mounting plate 71 and a mounting block 79. The mounting block 79 is fixedly connected to the upper surface of the connecting plate 61. The mounting plate 71 is fixedly connected to one end of the frame 2. A sliding rod 72 is fixedly connected inside the mounting plate 71. The sliding rod 72 is slidably connected inside the mounting block 79. A threaded rod 73 is rotatably connected inside the mounting plate 71. The threaded rod 73 is threadedly connected inside the mounting block 79. Fixing blocks 74 are fixedly connected to both ends of the threaded rod 73. A first gear 75 is fixedly connected to the surface of the threaded rod 73. A second gear 76 is meshed with the side of the first gear 75.

[0032] In this embodiment, by setting the threaded rod 73, the mounting block 79 can be moved to move the connecting plate 61, reducing the difficulty of moving the connecting plate 61 during use.

[0033] Specifically, a servo motor 77 is fixedly connected to the surface of the second gear 76. The servo motor 77 is fixedly connected inside the mounting plate 71. The servo motor 77 is provided to facilitate the rotation of the second gear 76.

[0034] Specifically, a mounting base 78 is fixedly connected to the surface of the servo motor 77, and the mounting base 78 is fixedly connected to the surface of the mounting plate 71.

[0035] Working principle: When using the equipment, the user feeds the treated wastewater into the frame 2 through the feed pipe 4. As the material enters the filter cylinder 5, the rotating mechanism drives the threaded extruder inside the filter cylinder 5 to squeeze and dewater the wastewater. The squeezed sludge is then discharged through the top of the frame 2. After use, when cleaning the surface of the filter cylinder 5, the user connects the water inlet pipe 62 to a water pipe. Water then flows through the water inlet pipe 62 into the connecting plate 61, moving through the connecting pipe 63. The water inside the connecting pipe 63 then flows through the connector 65 into the connecting ring 66. Water then enters the nozzle 67 through the connecting ring 66, and the nozzle 67 sprays water onto the surface of the filter cartridge 5 for cleaning. By setting up the cleaning device 6, the surface of the filter cartridge 5 is effectively cleaned, which reduces the likelihood of clogging on the surface of the filter cartridge 5 after long-term use, thus preventing sewage from being discharged from the filter cartridge 5 when the equipment is used again. This cleaning device 6, through the connecting ring 66 and the nozzle 67, sprays water onto the surface of the filter cartridge 5 for cleaning, facilitating sewage discharge and improving the service life of the equipment.

[0036] When the equipment cleans the surface of the filter cartridge 5, the user starts the servo motor 77 to drive the second gear 76 to rotate. When the second gear 76 rotates, it drives the first gear 75 to rotate. Then, when the first gear 75 rotates, it drives the threaded rod 73 to rotate. When the threaded rod 73 rotates, it drives the mounting block 79 to move, which in turn moves the connecting plate 61 inside the sliding hole 69. By setting the auxiliary component 7, the connecting plate 61 is effectively moved, which in turn moves the connecting ring 66 and the nozzle 67. This reduces the difficulty of thoroughly cleaning the surface of the filter cartridge 5 when using the existing equipment. This auxiliary component 7 realizes the movement of the cleaning device 6, which facilitates the equipment to thoroughly clean the filter cartridge 5 and improves the practicality of the equipment.
