Technical Field

[0001] This utility model belongs to the field of sewage pump technology, and specifically relates to a sewage pump anti-clogging filter device used in the process of regulating drainage. Background Technology

[0002] The anti-clogging filter device for sewage pumps used in the drainage process is a key auxiliary device to ensure the normal operation of the sewage pump. Installed at the front end of the sewage pump, it effectively intercepts solid impurities and silt from the sewage through a multi-layer precision filter structure. Its unique design prevents impurities from directly entering the sewage pump, preventing pump blockage and wear, extending the service life of the sewage pump, ensuring smooth and efficient drainage, and reducing maintenance costs.

[0003] However, existing sewage pump anti-clogging filtration devices still have some shortcomings. Although the filter screen structure can achieve a certain function of intercepting silt, the filter screen structure is generally fixed and not conducive to disassembly. Over a long period of time, silt and other impurities will also clog the filter screen structure. Because it is not easy to disassemble later, the efficiency of subsequent cleaning and maintenance of the filter screen structure is reduced, which is very inconvenient. Utility Model Content

Detailed Implementation

[0021] Example

[0022] refer to Figures 1 to 5 This embodiment provides a sewage pump anti-clogging filtration device for use in the drainage process, comprising a pump body 1, a mounting plate 2 threadedly connected to the top of the pump body 1, a drive motor 3 fixedly connected to the top of the mounting plate 2, a connecting pipe 6 fixedly connected to the front side of the pump body 1, a first connecting flange 7 fixedly connected to the front side of the connecting pipe 6, a second connecting flange 10 snapped onto the front side of the first connecting flange 7, a connecting pipe 21 fixedly connected to the front side of the second connecting flange 10, a filter plate 22 slidably connected to the inner wall of the connecting pipe 21, a first slot 11 extending into the interior of the first connecting flange 7, a second slot 12 on the inner wall of the first slot 11, a circular groove 13 on the inner side of the first slot 11, and a first clip snapped onto the inner side of the first slot 11. Block 15, the outer side of the first locking block 15 is fixedly connected to a second locking block 16 that matches the second locking groove 12. The second locking block 16 is locked into the inner side of the circular groove 13. In use, the filter plate 22 structure can effectively filter the sewage inside the connecting pipe 21. The first locking block 15 can send the second locking block 16 into the circular groove 13. The second locking block 16 is adjusted to a corresponding angle with the second locking groove 12, thereby effectively locking the second connecting flange 10. When the filter plate 22 structure needs to be cleaned later, the second locking block 16 is adjusted to a corresponding angle with the second locking groove 12, and then the first locking block 15 can be directly pulled out. This allows the connecting pipe 21 structure to be disassembled and reassembled separately, and also facilitates the user to clean or maintain the filter plate 22 structure on the inner wall of the connecting pipe 21 later.

[0023] refer to Figures 1 to 4 A retaining spring 14 matching the second retaining block 16 is provided on the inner side of the circular groove 13. The rear side of the second retaining block 16 is engaged with the front side of the retaining spring 14. The second retaining block 16 is engaged with the inner side of the circular groove 13 through the retaining spring 14. A sealing block 17 is fixedly connected to the front side of the first retaining block 15. The sealing block 17 covers the front side of the first retaining groove 11. A protrusion 18 is fixedly connected to the front side of the sealing block 17. The protrusion 18 has an arc-shaped corner. Due to the presence of the retaining spring 14, the engagement of the retaining spring 14 can further limit the position of the second retaining block 16. While improving the engagement stability of the second retaining block 16, it can also effectively improve the engagement stability of the second connecting flange 10.

[0024] refer to Figures 1 to 5 A positioning block 19 is fixedly connected to the rear side of the second connecting flange 10, and a positioning groove 9 matching the positioning block 19 is fixedly connected to the front side of the first connecting flange 7. The positioning block 19 is snapped into the inner side of the positioning groove 9. Due to the presence of the positioning block 19, the snapping of the positioning block 19 can predefine the position of the second connecting flange 10, and can also effectively improve the accuracy of the snapping of the first snapping block 15.

[0025] refer to Figures 1 to 5 A sealing groove 8 is provided on the front side of the first connecting flange 7, and a sealing ring 20 that matches the sealing groove 8 is fixedly connected to the rear side of the second connecting flange 10. The sealing ring 20 covers the inner side of the sealing groove 8. Due to the presence of the sealing ring 20, the sealing ring 20 can effectively seal the connection point of the second connecting flange 10, thereby achieving a good dustproof sealing effect.

[0026] refer to Figure 1 The mounting plate 2 is fixedly connected to the outer side of a first fixing block 4. The top of the first fixing block 4 is threadedly connected to a first bolt 5. The bottom of the first bolt 5 is threadedly connected to the inside of the pump body 1. The mounting plate 2 is threadedly connected to the top of the pump body 1 through the first fixing block 4 and the first bolt 5. Due to the presence of the first bolt 5, the screwing in of the first bolt 5 can effectively fix the position of the mounting plate 2 to prevent the mounting plate 2 from shifting. When the mounting plate 2 needs to be removed later, the first bolt 5 can be unscrewed. It also facilitates the user to maintain the structure on the pump body 1 later.

[0027] refer to Figure 1The inner wall of the connecting pipe 21 is provided with a sliding groove 23 that matches the filter plate 22. The filter plate 22 is slidably connected to the inner wall of the connecting pipe 21 through the sliding groove 23. A second fixing block 24 is fixedly connected to the front side of the filter plate 22. A second bolt 25 is threadedly connected to one side of the second fixing block 24, and the other side of the second bolt 25 is threadedly connected to the inside of the connecting pipe 21. The opening of the sliding groove 23 facilitates the back-and-forth sliding of the filter plate 22. The screwing in of the second bolt 25 can effectively fix the position of the filter plate 22. When the filter plate 22 needs to be disassembled separately in the future, the second bolt 25 is unscrewed first, and then the filter plate 22 can be directly pulled out through the sliding groove 23. This also facilitates the user to replace or maintain the structure of the filter plate 22 in the future.

[0028] Operating principle and advantages: During use, the filter plate 22 structure can effectively filter the sewage inside the connecting pipe 21. Its first locking block 15 can send the second locking block 16 into the circular groove 13. Adjusting the second locking block 16 to a corresponding angle with the second groove 12 allows for effective engagement of the second connecting flange 10. When cleaning the filter plate 22 structure later, simply adjust the second locking block 16 to a corresponding angle with the second groove 12, and then pull out the first locking block 15. This allows for individual disassembly and assembly of the connecting pipe 21 structure, facilitating cleaning or maintenance of the filter plate 22 structure on the inner wall of the connecting pipe 21. The presence of the retaining spring 14 provides secondary positioning of the second locking block 16, improving the stability of the second locking block 16 and effectively enhancing the stability of the second connecting flange 10 engagement. The presence of the positioning block 19 ensures that the positioning block 19 can be engaged... The position of the second connecting flange 10 is predetermined, which can also effectively improve the accuracy of the first locking block 15. Due to the presence of the sealing ring 20, the sealing ring 20 can effectively seal the connection point of the second connecting flange 10, thereby achieving a good dustproof sealing effect. Due to the presence of the first bolt 5, the screwing in of the first bolt 5 can effectively fix the position of the mounting plate 2 to prevent the mounting plate 2 from shifting. When the mounting plate 2 needs to be removed later, the first bolt 5 can be unscrewed. It also facilitates the user's maintenance of the structure on the pump body 1 later. Due to the opening of the slide groove 23, the filter plate 22 can slide back and forth. The screwing in of the second bolt 25 can effectively fix the position of the filter plate 22. When the filter plate 22 needs to be removed separately later, the second bolt 25 can be unscrewed first, and then the filter plate 22 can be directly pulled out through the slide groove 23. This also facilitates the user's replacement or maintenance of the filter plate 22 structure later.
