[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-6 As shown, the wastewater treatment tank for wastewater treatment provided in this embodiment includes a tank body 1. A wastewater pipe 2 is fixedly connected to one end of the tank body 1. A wastewater zone 101, a filtration zone 102, and a clean water zone 103 are arranged sequentially on the inner side of the tank body 1. A filtration mechanism is installed in the filtration zone 102. A water outlet pipe 3 is connected to one side of the clean water zone 103. The filtration mechanism includes a first motor 4 installed on the outside of the tank body 1. The output end of the first motor 4 is connected to a rotating shaft 5 located inside the tank body 1. A filter cylinder 6 is connected to the outside of the rotating shaft 5. Multiple lifting plates 7 are evenly connected to the outer wall of the filter cylinder 6. An arc-shaped plate 8 is provided at the top of the clean water zone 103. A tooth 9 that cooperates with the lifting plate 7 is connected to the side of the arc-shaped plate 8 near the filter cylinder 6. Wastewater enters the tank 1 and passes through the wastewater zone 101, the filtration zone 102, and the clean water zone 103 in sequence, and is discharged from the outlet pipe 3. Through the setting of the filtration mechanism, when the wastewater passes through the filtration zone 102, the impurities in it are intercepted by the filter cylinder 6. The first motor 4 drives the filter cylinder 6 to rotate, and the lifting plate 7 lifts the impurities in the water out of the water surface. Before rotating to the arc plate 8, the insert teeth 9 scrape the impurities on the outer wall of the filter cylinder 6 and the lifting plate 7 into the arc plate 8, thereby automatically cleaning the impurities without causing blockage.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a conveying pipe 10 connected to the arc plate 8 is fixedly connected to the outer wall of the front of the box 1. A discharge pipe 11 is fixedly connected to the bottom of the conveying pipe 10. A second motor 12 is installed on the outer wall of the back of the box 1. The output end of the second motor 12 is connected to a conveying auger 13 located inside the arc plate 8. One end of the conveying auger 13 extends to the inside of the conveying pipe 10. A collection box 14 is provided below the discharge pipe 11. An electric telescopic rod 15 is installed at one end of the discharge pipe 11. An extrusion plate 16 is connected to the output end of the electric telescopic rod 15. A filter plate 17 is fixedly connected to the inside of the collection box 14. The extrusion plate 16 is slidably installed on the top of the filter plate 17. A drain pipe 18 located below the filter plate 17 is fixedly connected to the outer wall of the collection box 14. It should be noted that the second motor 12 drives the conveying auger 13 to rotate, thereby discharging the impurities on the arc plate 8 into the collection box 14 through the conveying pipe 10 and the discharge pipe 11. The electric telescopic rod 15 drives the extrusion plate 16 to move, which can extrude impurities, reduce space occupation, and squeeze out some water, which is convenient for later transfer and transportation. The squeezed water is discharged from the drain pipe 18 through the filter plate 17.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, two symmetrically distributed guide plates 19 are fixedly connected to the inner side of the sewage zone 101. Water-permeable holes 20 are provided on the arc-shaped plate 8, through holes are provided on the filter cylinder 6, and filter grooves 21 are provided on the lifting plate 7. The inner wall of the filtration zone near the sewage zone is an arc-shaped inner wall that mates with the filter cylinder 6. It should be noted that the width of the filter groove 21 is greater than or equal to the diameter of the through holes on the filter cylinder 6. The water-permeable holes 20 on the arc-shaped plate 8 can control some of the water in the impurities. By fixing two symmetrically distributed guide plates 19 to the inner side of the sewage zone 101, sewage enters from the middle of the filter cylinder 6, preventing impurities from entering both ends of the filter cylinder 6. The filter grooves 21 on the lifting plate 7 mate with the insert teeth 9, thereby scraping off impurities.

[0028] In this embodiment, as Figures 1-6 As shown in the figure, the working process of a sewage treatment tank for sewage treatment provided in this embodiment is as follows:

[0029] Step 1: After entering the tank 1, the sewage passes through the sewage zone 101, the filtration zone 102 and the clean water zone 103 in sequence and is discharged from the outlet pipe 3.

[0030] Step 2: When the wastewater passes through the filtration zone 102, the impurities in it are trapped by the filter cylinder 6. The first motor 4 drives the filter cylinder 6 to rotate, and the lifting plate 7 lifts the impurities in the water out of the water surface. Before rotating to the arc plate 8, the insert teeth 9 scrape the impurities on the outer wall of the filter cylinder 6 and the lifting plate 7 into the arc plate 8, thereby automatically cleaning the impurities and preventing blockage.

[0031] Step 3: The second motor 12 drives the conveying auger 13 to rotate, thereby discharging the impurities on the arc plate 8 into the collection box 14 through the conveying pipe 10 and the discharge pipe 11. The electric telescopic rod 15 drives the extrusion plate 16 to move, which can extrude impurities, reduce space occupation, and squeeze out some water, which is convenient for later transfer and transportation. The squeezed water is discharged from the drain pipe 18 through the filter plate 17.

[0032] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
