DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 The sewage treatment equipment comprises a treatment tank 1, on which a sewage discharge pipe 2 and a treatment agent addition pipe 3 are provided. A filter cartridge 5 is provided inside the treatment tank 1, and filter materials such as filter cotton are filled in the filter cartridge 5. The filter cartridge 5 is arranged opposite to the sewage discharge pipe 2, and sewage can directly enter the filter cartridge 5 from the sewage discharge pipe 2 for filtering. A seepage port 6 is provided on the side wall of the filter cartridge 5. A rotating shaft 13 is rotatably connected inside the treatment tank 1, and a plurality of fixed shafts 14 are fixedly connected to the rotating shaft 13. The fixed shaft 14 can also stir the liquid when the rotating shaft 13 rotates, thereby increasing the stirring range. A driving assembly is provided at the bottom of the filter cartridge 5, and the driving assembly is used to drive the rotating shaft 13 to rotate. A stirring assembly for stirring sewage and the treatment agent is also provided inside the treatment tank 1.

[0025] Reference Figure 2 and Figure 3 The driving assembly includes a driving cylinder 7, and a slide plate 9 is slidably connected inside the driving cylinder 7. A plurality of springs 10 are arranged between the bottom of the slide plate 9 and the inner bottom surface of the driving cylinder 7. The spring 10 is used to reset the filter cylinder 5. A plurality of slide rods 8 are fixedly connected to the slide plate 9. The plurality of slide rods 8 guide the filter cylinder 5 to ensure that the filter cylinder 5 moves in the vertical direction, thereby ensuring the stability of the overall structure of the device. One end of the slide rod 8 extends to the outside of the driving cylinder 7, and the end of the slide rod 8 located outside the driving cylinder 7 is fixedly connected to the bottom of the filter cylinder 5. The driving assembly also includes a transmission member, which is arranged between the filter cylinder 5 and the rotating shaft 13. The transmission member is used to drive the rotating shaft 13 to rotate. By using the driving assembly, the rotating shaft 13 can rotate under the gravity of the sewage itself to achieve the purpose of stirring. In this way, there is no need to use motors and other equipment for driving, which saves sewage treatment costs and reduces maintenance and monitoring costs.

[0026] Reference Figure 1and Figure 2 The transmission parts include a gear 11 and a rack 12. The gear 11 is fixedly sleeved on the rotating shaft 13, and the rack 12 is fixedly connected to the filter cartridge 5. The gear 11 and the rack 12 are meshed with each other. By using the transmission parts, the rack 12 will drive the rotating shaft 13 to rotate when moving up and down, thereby realizing the stirring operation.

[0027] Reference Figure 4 and Figure 5 The stirring assembly includes a plurality of connecting shafts 15, which are rotatably connected between two fixed shafts 14 located on the same side. A plurality of stirring plates 16 are fixedly connected to the connecting shafts 15, and a plurality of driving blocks 17 are fixedly connected to the inner wall of the treatment tank 1. The stirring plates 16 located on the same connecting shaft 15 are arranged at equal intervals in the circumferential direction. The stirring plates 16 rotate under the action of the driving blocks 17, and at the same time rotate around the rotating shaft 13 under the action of the rotating shaft 13, so that the liquid in the treatment tank 1 can be fully stirred and the efficiency of sewage treatment can be improved.

[0028] Reference Figure 5 The driving blocks 17 are arranged at equal intervals in the circumferential direction. When the connecting shaft 15 rotates around the rotating shaft 13, the stirring plate 16 can rotate around the connecting shaft 15 under the action of the driving blocks 17, which can increase the stirring range of the stirring plate 16 and ensure the mixing effect of the sewage and the treatment agent.

[0029] Reference Figure 1 A plurality of support frames 4 are fixedly installed inside the treatment tank 1, and the outer ring of the support frame 4 is adapted to the inner wall of the treatment tank 1. The support frame 4 supports the treatment tank 1 to prevent the treatment tank 1 from deforming and causing sewage leakage, thereby ensuring the stability of the overall structure of the device.

[0030] The specific working principle of the utility model is as follows:

[0031] When sewage enters the treatment tank 1 through the sewage discharge pipe 2, the sewage will first enter the filter cartridge 5, and the filter cotton and other filter materials filled in the filter cartridge 5 will filter the sewage, and the sewage will slowly be discharged from the seepage port 6 after filtration. When the sewage is poured into the filter cartridge 5, the weight of the filter cartridge 5 will increase and move downward, and press the slide bar 8 and the slide plate 9 downward, so that the spring 10 is in a compressed state. The downward movement of the filter cartridge 5 will drive the rack 12 to move downward, so that the gear 11 rotates, and then drives the rotating shaft 13 to rotate, so that the fixed shaft 14 rotates around the rotating shaft 13, and the fixed shaft 14 can stir the treatment tank. The sewage and the treatment agent in the treatment tank 1 are mixed fully, and then the rotation of the fixed shaft 14 can drive the connecting shaft 15 and the stirring plate 16 to rotate around the rotating shaft 13. When the stirring plate 16 contacts the driving block 17 during the rotation process, the driving block 17 squeezes the stirring plate 16 to make the stirring plate 16 rotate. In this way, the stirring plate 16 rotates around the rotating shaft 13 under the action of the rotating shaft 13, and at the same time, it also rotates around the connecting shaft 15 under the action of the driving block 17, so that the stirring plate 16 can fully mix the sewage and the treatment agent, thereby ensuring the adequacy of sewage treatment and the quality of treatment;

[0032] On the contrary, in the process of sewage in the filter cartridge 5 being discharged from the seepage port 6, the weight of the filter cartridge 5 is reduced, and under the elastic force of the spring 10, the slide plate 9 and the slide rod 8 move up and push up the filter cartridge 5. The upward movement of the filter cartridge 5 drives the rack 12 to move up and reset, so that the gear 11 and the rotating shaft 13 are reversed, and then the fixed shaft 14 and the stirring plate 16 are driven to rotate again, thereby re-mixing the sewage and the treatment agent. No manual processing is required by the staff, thus saving production costs.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
