Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides a technical solution:

[0026] A wastewater treatment tank for wastewater treatment equipment includes a wastewater treatment tank body 1. A first cover 2 is hinged to the top of the wastewater treatment tank body 1. An inlet 3 is fixedly installed on the top of the first cover 2. An outlet 4 is fixedly installed on the outer surface of the wastewater treatment tank body 1. A handle 5 is fixedly installed on the top of the first cover 2. A movable tank 7 is provided inside the wastewater treatment tank body 1. A lifting assembly for moving the movable tank 7 is provided inside the wastewater treatment tank body 1. The lifting assembly includes a threaded rod 14, a connecting block 15, and a filter screen 16. The filter screen 16 is fixedly connected to the bottom of the movable tank 7. Two symmetrically distributed connecting blocks 15 are fixedly connected to the inner wall of the movable tank 7. The threaded rod 14 is threadedly sleeved inside the two connecting blocks 15. The two threaded rods 14 are located inside the movable tank 7. The filter screen 16 is sleeved with the two threaded rods 14. A power assembly for driving the lifting assembly is provided inside the wastewater treatment tank body 1. The rotation of the threaded rod 14 drives the movable tank 7 to move upward through the connecting block 15.

[0027] Furthermore, the power assembly includes a drive motor 6, a waterproof box 10, a first bevel gear 12, and a second bevel gear 13. Two symmetrically distributed waterproof boxes 10 are fixedly connected to the inner wall of the sewage treatment tank body 1. Both waterproof boxes 10 are located below the filter screen 16. The inner walls of both waterproof boxes 10 are rotatably connected to the second bevel gear 13, and the top inner walls of both waterproof boxes 10 are rotatably connected to the first bevel gear 12. The first bevel gear 12 and the second bevel gear 13 mesh perpendicularly. The drive motor 6 is fixedly installed on the outer surface of the sewage treatment tank body 1. The output end of the drive motor 6 passes through the sewage treatment tank body 1 and the waterproof box 10 and is fixedly connected to the end of the adjacent second bevel gear 13. The output end of the drive motor 6 drives the second bevel gear 13 connected to it to rotate. Through the perpendicular meshing of the first bevel gear 12 and the second bevel gear 13, the rotation direction is converted to the vertical direction.

[0028] Furthermore, a rotating shaft 11 is rotatably connected between the two waterproof boxes 10. The two ends of the rotating shaft 11 are fixedly connected to the second bevel gear 13, and the threaded rod 14 is fixedly connected to the corresponding first bevel gear 12. Since the two waterproof boxes 10 are connected by the rotating shaft 11, the two second bevel gears 13 rotate synchronously, driving the two threaded rods 14 to rotate simultaneously.

[0029] Furthermore, the outer surface of the mobile tank 7 is provided with multiple annularly distributed through holes 9, and the treated wastewater enters the wastewater treatment tank body 1 through the filter screen 16 or multiple through holes 9.

[0030] Furthermore, the inner wall of the sewage treatment tank body 1 has two symmetrically distributed rectangular grooves 19, and the outer surface of the mobile tank 7 is fixedly connected to two symmetrically distributed sliding blocks 17. The sliding blocks 17 are slidably connected to the interior of the corresponding rectangular grooves 19, and the mobile tank 7 rises stably along the sliding blocks 17 under the restriction of the rectangular grooves 19.

[0031] Furthermore, a second cover 18 is hinged to the top of the mobile tank 7, and a connection port 8 is fixedly installed on the top of the second cover 18. The connection port 8 fits against the bottom of the feed port 3, and sewage enters the mobile tank 7 through the connection port 8.

[0032] Working principle: When the wastewater treatment equipment needs to be used, the filter screen 16 covers the bottom of the mobile tank 7 to filter impurities in the wastewater. Two threaded rods 14 are connected to the mobile tank 7 via connecting blocks 15, but at this time, the mobile tank 7 is not driven to move. The first bevel gear 12 and the second bevel gear 13 inside the waterproof tank 10 are stationary, waiting for the drive motor 6 to start. When wastewater needs to be treated, the wastewater and any impurities it may contain are poured into the wastewater treatment tank body 1 through the inlet 3. The wastewater enters the mobile tank 7 through the connecting port 8, where it is treated and filtered through the filter screen 16. The treated wastewater then enters the wastewater treatment tank body 1 through the filter screen 16 or multiple through holes 9, and is discharged through the outlet 4. When the wastewater in the mobile tank 7 reaches a certain treatment capacity or needs to be cleaned, the upward... Pulling handle 5 opens the first box cover 2, starts the drive motor 6, and drives the second bevel gear 13 connected to it to rotate. Through the vertical meshing of the first bevel gear 12 and the second bevel gear 13, the rotation direction is changed to the vertical direction. Since the two waterproof boxes 10 are connected by the rotating shaft 11, the two second bevel gears 13 rotate synchronously, driving the two threaded rods 14 to rotate simultaneously. The rotation of the threaded rods 14 drives the moving tank 7 to move upward through the connecting block 15. The moving tank 7 rises steadily along the sliding block 17 under the restriction of the rectangular groove 19. As the moving tank 7 rises, the second box cover 18 is opened, and the filter screen 16 and the inside of the moving tank 7 can be cleaned. After cleaning the filter screen 16 and the moving tank 7, the second box cover 18 is closed, and the moving tank 7 is lowered back to its original position by reversing the operation of the drive motor 6, waiting for the next sewage treatment.
