[0032] like Figure 4As shown, the filter cleaning assembly 3 includes a primary motor 31, which provides power to the assembly. The primary motor 31 is fixedly connected to the outer casing 1. A rotating shaft 32 is fixedly connected to the output end of the primary motor 31, which is used to connect with the spiral blades 33. The spiral blades 33 are fixedly connected to the outside of the rotating shaft 32, which are used to filter wastewater and transport impurities to the discharge pipe 343. A cleaning cylinder 34 is provided outside the spiral blades 33, which is used to filter wastewater and clean impurities. The cleaning cylinder 34 penetrates and is fixedly connected to the outer casing 1. A connecting pipe 35 is provided at the upper part of the cleaning cylinder 34. It is used to transport sewage to the cleaning cylinder 34. The cleaning cylinder 34 includes a filter cylinder 341, which is used to filter sewage and remove impurities from the sewage. The right side of the filter cylinder 341 is fixedly connected to the outer shell 1. The connecting pipe 35 passes through the filter cylinder 341 and is fixedly connected. The cleaning cylinder 34 also includes a shell 342, which is used to connect the various components. It is located on the left side of the outer shell 1. The shell 342 is fixedly connected to the left side of the filter cylinder 341. The rotating shaft 32 is rotatably connected to the shell 342. The lower part of the shell 342 is fixedly connected to the discharge pipe 343, which is used to facilitate the discharge of impurities in the cleaning cylinder 34.

[0033] Please see Figure 1 - Figure 3 The mixing component 2 includes a second motor 21, which provides power to the mixing component 2. The second motor 21 is fixedly connected to the outer casing 1. A rotating rod 22 is fixedly connected to the output end of the second motor 21, which is used to cooperate in the mixing of sewage and chemicals. The rotating rod 22 is rotatably connected to the outer casing 1. Multiple stirring rods 23 are fixedly connected to the outside of the rotating rod 22, which are used to cooperate in stirring the liquid to assist in the mixing of sewage and chemicals.

[0034] Furthermore, an inlet pipe 11 is fixedly connected to the left side of the outer casing 1, which is used to send the sewage after removing larger impurities into the outer casing 1. An outlet pipe 13 is fixedly connected to the lower right side of the outer casing 1, which is used to discharge the pretreated sewage. An inlet pipe 12 is fixedly connected to the left side of the top surface of the outer casing 1, which is used to send the sewage treatment agent into the outer casing 1. A baffle 14 is fixedly connected to the middle of the inner wall of the outer casing 1, which is used to separate the space inside the outer casing 1. A connecting pipe 35 passes through and is fixedly connected to the baffle 14. A vertical plate 15 is fixedly connected to the middle of the top surface of the baffle 14, which is used to connect the various components. Guide plates 16 are fixedly connected to the right side of the vertical plate 15 and the left side of the inner wall of the outer casing 1, which are used to guide the sewage and further assist in the mixing of sewage and agents. A guide block 17 is fixedly connected to the right side of the top surface of the baffle 14, which is used to guide the sewage to the connecting pipe 35.

[0035] Working principle: During use, wastewater is sent into the outer casing 1 through the inlet pipe 11, while the reagent is sent into the outer casing 1 through the liquid inlet pipe 12. Then, the second motor 21 is turned on, which drives the rotating rod 22 to rotate. The stirring rod 23 connected to the rotating rod 22 is also driven to rotate, thereby mixing the wastewater and the reagent. When the wastewater level overflows the baffle 14, the wastewater flows to the right side of the outer casing 1 and is guided by multiple guide plates 16 to the guide block 17. As the water flows through the multiple guide plates 16, the guide plates 16 guide the liquid and assist in further mixing of the liquid and the reagent. Meanwhile, guide block 17 will guide the sewage to connecting pipe 35. The sewage will enter the filter cylinder 341 through the connecting pipe 35. At this time, motor 31 is turned on. The liquid in the sewage will fall into the lower part of the outer shell 1 through the filter cylinder 341 and be discharged through the outlet pipe 13. The impurities in the sewage will remain in the filter cylinder 341. Motor 31 will drive the rotating shaft 32 to rotate. The spiral blades 33 connected to the rotating shaft 32 will rotate accordingly, thereby pushing the impurities in the filter cylinder 341 to move towards the discharge pipe 343 at the lower part of the shell 342 until the impurities are moved to the discharge pipe and discharged by 343.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
