A filter screen B22 is installed at the top of the mounting plate B21. A rotating block 23 is set inside the filter screen B22. A stop block A24 is installed at the bottom of the rotating block 23. A stop block B25 is installed at the top of the rotating block 23. A scraper 26 is installed on the surface of the stop block B25. A protrusion 27 is installed at the top of the stop block B25. A fan blade 28 is installed on the surface of the protrusion 27. By setting the groove 5, the limiting groove 6, the rotating groove 7, the sliding groove 8, the filter box 9, the fixing plate 10, the pulling block 11, the side plate 12, the fixing block 13, the fixing groove 14, the threaded rod 15, the handle 16, the support plate 17, the mounting plate A18, the filter screen A19, the partition 20, the mounting plate B21, the filter screen B22, the rotating block 23, the stop block A24, the stop block B25, the scraper 26, the protrusion 27 and the fan blade 28, the wastewater treatment efficiency and filtration accuracy are improved. The sliding connection between the fixed plate 10 and the outer casing 1 allows the filter box 9 to be adjusted in position as needed, facilitating maintenance and filter media replacement. Furthermore, the use of the threaded rod 15 and the throttle handle 16 simplifies the operation process and reduces labor intensity.The overall structure is compact and occupies a small area, making it suitable for space-constrained working environments. Support columns 2 are fixedly installed at the four corners of the outer shell 1. The filter box 9 is slidably connected to the outer shell 1 via sliding grooves 8, providing a stable structural foundation and ensuring the stability of the entire wastewater treatment device during operation. The sliding connection between the filter box 9 and the outer shell 1 via the sliding grooves 8 allows the filter box 9 to be easily adjusted according to actual needs, facilitating daily maintenance and filter media replacement, and improving operational flexibility and convenience.

[0025] Example 2

[0026] Please see Figures 1-3The outer casing 1 has a connecting block 29 at its top, and a mixing box 30 is mounted on the top of the connecting block 29. A rotating groove 31 is opened on the right side of the mixing box 30, and a motor 32 is mounted on the right side of the mixing box 30. A stirring rod 33 is mounted on the output end of the motor 32, and stirring blades 34 are mounted on the surface of the stirring rod 33. A soft plug 35 is located at the top of the mixing box 30, and a top plate 36 is mounted on the top of the soft plug 35. A dosing port 37 is mounted on the top of the top plate 36, allowing for convenient addition of chemicals during wastewater treatment. The stirring rod 33 and stirring blades 34 are driven by the motor 32 to achieve thorough mixing, improving the reaction efficiency between the chemicals and wastewater. The design of the soft plug 35 and the top plate 36 facilitates the addition of chemicals by operators and also ensures... The sealing performance of the mixing tank 30 is ensured, preventing leakage during the mixing process. These structural features together improve the wastewater treatment effect and ease of operation. The stirring rod 33 is rotatably connected to the mixing tank 30 through the rotating groove 31. The stirring blades 34 are evenly distributed on the surface of the stirring rod 33. The soft plug 35 is slidably connected to the mixing tank 30, and the top plate 36 is slidably connected to the mixing tank 30, enhancing the treatment effect. The sliding connection between the soft plug 35 and the mixing tank 30, as well as the sliding connection between the top plate 36 and the mixing tank 30, not only facilitates the operator to add chemicals and observe the mixing situation, but also ensures the good sealing performance of the mixing tank 30 during the chemical addition and stirring process, preventing wastewater overflow and odor emission.

[0027] Working principle: First, place the outer casing 1 in the desired position, ensuring the support column 2 firmly supports it. Then, start the motor 32 on the right side of the mixing tank 30, causing the motor 32 to drive the stirring rod 33 to rotate. The stirring rod 33, through the rotating groove 31, drives the stirring blade 34 to rotate inside the mixing tank 30. Then, fix the top plate 36 to the top of the mixing tank 30 using the soft plug 35. The waste liquid can then be poured into the mixing tank 30 through the dosing port 37. Dosing through the dosing port 37 initiates mixing. After mixing, the liquid can be allowed to pass through the connecting block. 29 flows into the interior of the outer casing 1. The waste liquid then passes through filter screens A19 and B22 inside the filter box 9 for filtration. During filtration, the impact of the falling waste liquid causes the fan blades 28 on the surface of the protrusion 27 to rotate the baffle B25 at the top of filter screen B22 or A19. Simultaneously, the rotating block 23 rotates inside filter screens B22 and A19, and the baffle A24 rotates at the bottom of filter screens B22 and A19. The baffle B25 also causes the scraper 26 to rotate at the top of filter screens B22 and A19, thus preventing damage during prolonged filtration. During the process, filter screens B22 and A19 may become clogged. After filtration, the liquid will continue to flow downwards into the collection tank 3 and out through the drain port 4. When filtration is complete and filter screens A19 and B22 need to be cleaned, first squeeze the handle 16 and rotate it to make the threaded rod 15 rotate outwards through the rotating groove 7 inside the outer casing 1. When the threaded rod 15 has completely rotated out of the inner casing 1 through the rotating groove 7, it is ready. Then, remove it from the inside of the fixing block 13 through the fixing groove 14. Then, squeeze the pull block 11 and pull it to make the fixing plate 10 slide out of the outer casing through the groove 5. Inside the housing 1, the side plate 12 slides backward together, allowing the side plate 12 to slide out of the housing 1 through the limiting groove 6. Once the fixing plate 10 has completely slid out of the housing 1 through the sliding groove 8, the filter screen B22 is then pinched and pulled upward, causing the bottom end of the mounting plate B21 to detach from the top end of the partition 20 and slide completely out of the housing 9. Then the partition 20 is removed from the housing 9. Finally, the filter screen A19 is pinched and pulled upward, causing the bottom end of the mounting plate A18 to detach from the top end of the support plate 17, so that the staff can clean the filter screen B22 and the filter screen A19.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
