[0001] This invention belongs to the field of wastewater filtration technology, and in particular relates to a self-cleaning wastewater filtration device. Background Technology

[0002] Wastewater contains various impurities. If these substances accumulate in the filter container, they can clog the filter material, thereby reducing filtration efficiency and treatment capacity. Therefore, during wastewater filtration, it is necessary to stop the equipment and clean or replace the filter components to ensure the wastewater filtration effect. Summary of the Invention

[0003] In view of this, the present invention aims to provide a self-cleaning sewage filtration device to solve the technical problem of needing to stop the equipment to clean the filter container or replace the filter components.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a self-cleaning sewage filtration device, comprising a filter box, a filter assembly inside the filter box, a filter chamber inside the filter assembly, a drainage chamber between the filter box and the filter assembly, an expansion box on the filter box, the expansion box and the filter assembly increasing the space of the filter chamber, two fixed columns on the filter box, the filter assembly slidably mounted on the two fixed columns, the expansion box mounted on the two fixed columns, and when the sewage inside the expanded filter chamber rises to the top of the expansion box, a driving component inside the fixed columns drives the filter assembly to slide on the two fixed columns to remove impurities attached to the filter assembly.

[0005] Furthermore, the fixed column is provided with a water injection chamber inside, and the bottom end of the water injection chamber is provided with a discharge component that seals the water injection chamber. When the water level in the water injection chamber reaches a certain height, the drive component is activated.

Detailed Implementation

[0016] As shown in the figure, a self-cleaning sewage filtration device includes a filter box 1, a filter assembly 2 inside the filter box 1, a filter chamber 3 inside the filter assembly 2, a drainage chamber 4 between the filter box 1 and the filter assembly 2, an expansion box 8 on the filter box 1, the expansion box 8 and the filter assembly 2 increasing the space of the filter chamber 3, two fixed columns 10 on the filter box 1, the filter assembly 2 slidingly mounted on the two fixed columns 10, and the expansion box 8 mounted on the two fixed columns 10. When the sewage inside the expanded filter chamber 3 rises to the top of the expansion box 8, the driving component 13 inside the fixed column 10 drives the filter assembly 2 to slide on the two fixed columns 10 to remove impurities attached to the filter assembly 2.

[0017] As the filter assembly 2 becomes clogged, the amount of sewage flowing into the filter chamber 3 increases continuously. When the sewage reaches a certain level, it will drive the drive assembly 13 inside the fixed column 10 to slide the filter assembly 2 on the fixed column 10, and the fixed column 10 will scrape off the filter residue on the filter assembly 2.

[0018] The lower end of the filter box 1 is provided with a drainage layer 5 that communicates with the drainage chamber 4. The drainage chamber 4 is connected to the drainage layer 5 through a connecting hole. The drainage layer 5 is provided with a water outlet hole 7. The upper end of the expansion box 8 is provided with a water injection hole 9.

[0019] In this embodiment, the fixed column 10 is provided with a water injection chamber 11 inside, and the bottom end of the water injection chamber 11 is provided with a discharge component 12 that seals the water injection chamber 11. When the water level in the water injection chamber 11 reaches a certain height, the drive component 13 is driven.

[0020] As the sewage level inside the filter chamber 3 rises, the sewage will enter the water injection chamber 11. When the water level in the water injection chamber 11 reaches a certain height, it will drive the drive assembly 13 to rotate, and the drive assembly 13 will drive the filter assembly 2 to slide on the fixed column 10.

[0021] In this embodiment, the discharge assembly 12 includes a fixed sleeve 12-1, a movable cylinder 12-3 slidably disposed inside the fixed sleeve 12-1, a mounting bracket 12-2 disposed on the fixed sleeve 12-1, a spring 12-10 disposed between the movable cylinder 12-3 and the mounting bracket 12-2, a first limiting part 12-7 and a second limiting part 12-8 disposed on the inner wall of the fixed sleeve 12-1, and an obstruction part disposed inside the movable cylinder 12-3. When the obstruction part is coupled with the first limiting part 12-7 or the second limiting part 12-8, it restricts the movable cylinder 12-3 from sliding inside the fixed sleeve 12-1. The movable cylinder 12-3 is provided with a drain hole 12-9. 2-3 When the fixed sleeve 12-1 slides to the point where the drain hole 12-9 slides out of the fixed sleeve 12-1, the water inside the water injection chamber 11 is discharged from the drain hole 12-9. The first limiting part 12-7 and the second limiting part 12-8 are arc-shaped grooves. The obstructing part includes a receiving groove 12-4, which is located inside the moving cylinder 12-3. An obstructing ball 12-6 is slidably provided inside the receiving groove 12-4. An obstructing spring 12-5 is provided between the receiving groove 12-4 and the obstructing ball 12-6. The first limiting part 12-7 or the second limiting part 12-8 cooperates with the obstructing ball 12-6. A turbine 13-1 is provided inside the moving cylinder 12-3.

[0022] When the water level in the injection chamber 11 reaches a certain height, the pressure exerted by the sewage on the moving cylinder 12-3 causes it to overcome the resistance of the obstructing spring 12-5 acting on the first limiting part 12-7 via the obstructing ball 12-6. The moving cylinder 12-3 then slides downwards inside the fixed sleeve 12-1 until the obstructing ball 12-6 enters the second limiting part 12-8. The drain hole 12-9 slides out from inside the fixed sleeve 12-1. Simultaneously, the moving cylinder 12-3 compresses the spring 12-10. Water inside the water injection chamber 11 is discharged outward through the drain hole 12-9. The water flow drives the turbine 13-1 to rotate. The rotation of the turbine 13-1 drives the filter assembly 2 to slide on the two fixed columns 10 through the drive assembly 13, rubbing off the impurities attached to the filter assembly 2. This reduces the amount of sewage in the filter chamber 3 and prevents it from replenishing the water injection chamber 11. After the water injection chamber 11 is discharged, the compressed spring 12-10 drives the moving cylinder 12-3 to break through the restriction of the second limiting part 12-8 and return to its original position.

[0023] The upper end of the fixed sleeve 12-1 is chamfered.

[0024] In this embodiment, the drive assembly 13 includes a turbine 13-1 and an output end 13-4, which are slidably connected. The two output ends 13-4 are connected by a connecting rod 13-3. A moving rod 13-2 is slidably provided inside the connecting rod 13-3. The moving rod 13-2 is connected to the turbine 13-1. The output end 13-4 is a gear. The filter assembly 2 includes an annular filter screen 2-1, which has toothed holes 2-2 that mesh with the output end 13-4.

[0025] The rotating turbine 13-1 drives the connecting rod 13-3 to rotate via the moving rod 13-2, which in turn drives the output end 13-4 to rotate, and the output end 13-4 drives the annular filter screen 2-1 to slide.

[0026] In this embodiment, the fixed column 10 is provided with a filter residue and wastewater discharge section 14. When the fixed column 10 slides, the filter residue and wastewater discharge section 14 scrapes off the filter residue attached to the annular filter screen 2-1 and discharges the wastewater from the filter chamber 3. The filter residue and wastewater discharge section 14 includes an arc-shaped sliding groove 14-1. The fixed column 10 is provided with an arc-shaped sliding groove 14-1. An arc-shaped plate 14-2 slides inside the arc-shaped sliding groove 14-1. An arc-shaped spring 14-3 is provided between the arc-shaped plate 14-2 and the arc-shaped sliding groove 14-1. The fixed column 10 is provided with a discharge hole 14-6. The discharge hole 14-6 is connected to the arc-shaped sliding groove 14-1. The arc-shaped sliding groove 14-1 is located at the end of the arc-shaped sliding groove 14-1 away from the arc-shaped spring 14-3. The fixed column 10 is provided with a limiting sliding groove 14-4. A sliding block 14-5 is provided inside the limiting sliding groove 14-4. The arc-shaped plate 14-2 is disposed on the sliding block 14-5.

[0027] The moving annular filter 2-1 pushes the arc plate 14-2 to slide inside the arc sliding groove 14-1 and compresses the arc spring 14-3. The discharge hole 14-6 of the moving arc plate 14-2 is exposed from the rear of the arc plate 14-2. After the arc plate 14-2 moves to the point where it can no longer move, the end face of the arc plate 14-2 close to the discharge hole 14-6 slides relative to the annular filter 2-1 and scrapes off the filter residue attached to the annular filter 2-1. Then, the filter chamber 3 moves while discharging through the discharge hole 14-6 to discharge the filtered residue from the discharge hole 14-6. When the annular filter 2-1 stops rotating, the compressed arc spring 14-3 pushes the arc plate 14-2 to reset and re-seal the discharge hole 14-6.
