[0023] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Refer to Figures 1-5A sewage treatment interception device for sewage treatment pools includes a sewage pool 10, in which thickener and flocculant are injected, a stirring motor 11 is fixedly connected to the outer wall of the sewage pool 10, and a rotating shaft 19 is rotatably connected to the output end of the stirring motor 11, and a rotating frame 25 is fixedly connected to both ends of the rotating shaft 19, and a plurality of second connecting rods 24 are fixedly connected between the ends of the two rotating frames 25 away from the rotating shaft 19, and a scraping groove connecting rod 26 is fixedly connected to the plurality of second connecting rods 24, and a scraping groove 18 is fixedly connected to the end of the scraping groove connecting rod 26 away from the second connecting rod 24, and a second filter plate 28 is fixedly provided at the bottom of the scraping groove 18.

[0025] The rotating shaft 19 is driven to rotate by the stirring motor 11, thereby driving the rotating frame 25 fixedly connected to the rotating shaft 19 to rotate, and the second connecting rod 24 fixed to the end of the rotating frame 25 performs a circular motion around the rotating shaft 19 as the axis, thereby stirring the sewage in the sewage pool 10, and the scraping groove 18 fixed on the second connecting rod 24 rotates together with the second connecting rod 24, thereby scraping off and collecting the viscous oil floating on the sewage surface and the flocculent particles sunk to the bottom, completing the cleaning of oil and impurities in the water and improving the effect of sewage treatment.

[0026] like Figure 3 , Figure 5 As shown, a plurality of second connecting rods 24 are rotatably connected to a plurality of second rotating rods 23 at one end away from the stirring motor 11, a plurality of second rotating rods 23 are rotatably connected to a plurality of first connecting rods 22 at one end away from the second rotating rods 24, a plurality of first connecting rods 22 are rotatably connected to a plurality of first rotating rods 21 at one end away from the second rotating rods 23, a plurality of first rotating rods 21 are fixedly connected to a rotating ring 20 at one end away from the first connecting rod 22, an eccentric disk 17 is slidably connected to the inner ring wall of the rotating ring 20, one end face of the eccentric disk 17 is fixedly connected to the inner wall of the sewage pool 10, and the position of the eccentric disk 17 deviating from the center of the circle is rotatably connected to the rotating shaft 19.

[0027] The second connecting rod 24 drives the rotating ring 20 to rotate together, so that the scraping groove 18 is always in a horizontal state, reducing the shaking of the scraping groove 18 when rotating, ensuring that the pollutants collected in the scraping groove 18 are always in the groove, and improving the pollution removal efficiency of the scraping groove 18.

[0028] like Figure 1 , Figure 2As shown in the figure, a water pump 14 is fixedly connected to the sewage tank 10. The input end of the water pump 14 is connected to a water inlet pipe 12 in a communicating manner. One end of the water inlet pipe 12 away from the water pump 14 is connected to the inside of the sewage tank 10 in a communicating manner. The output end of the water pump 14 is connected to a water outlet pipe 15 in a communicating manner. The water outlet pipe 15 is always located above the second connecting rod 24. A storage groove 16 is fixedly connected to the inner side wall of the sewage tank 10 away from the water pump 14. One end of the storage groove 16 away from the inner side wall of the sewage tank 10 is always at a certain distance from the scraping groove 18. A first filter plate 27 is fixedly connected to the storage groove 16. The notch of the storage groove 16 is directly opposite to the water outlet of the water outlet pipe 15.

[0029] The processed water is transported from the water outlet pipe 15 into the groove of the scraping groove 18 through the water pump 14, and the thick oil stains and particles in the scraping groove 18 are washed into the storage groove 16, completing the cleaning of the scraping groove 18 and the collection of oil stains and sewage particles. The sewage containing impurities in the storage groove 16 is secondarily filtered by the first filter plate 27, reducing the risk of blockage of the scraping groove 18.

[0030] In this embodiment, initially, the operator connects the power supply of this patent and connects the sewage discharge pipe to the sewage tank 10. Subsequently, a thickening agent and a flocculant are injected into the sewage tank 10. The flocculant causes the particulate impurities in the sewage to agglomerate into flocs, and the thickening agent can agglomerate the oil stains mixed in the sewage into a fatty state.

[0031] Subsequently, the operator starts the stirring motor 11. The stirring motor 11 drives the rotating shaft 19 to rotate. The rotating frame 25 fixedly connected to the rotating shaft 19 rotates together with the rotating shaft 19. The second connecting rod 24 fixed to the end of the rotating frame 25 makes a circular motion around the axis of the rotating shaft 19. The scraping groove 18 fixed to the second connecting rod 24 makes a circular motion together with the second connecting rod 24, stirring the sewage in the sewage tank 10 and accelerating the flocculation of particulate impurities and the agglomeration efficiency of oil stains.

[0032] A plurality of second rotating rods 23 are rotatably connected to one end of the second connecting rod 24 away from the stirring motor 11. Through the transmission of the plurality of second rotating rods 23 by the first connecting rod 22 and the first rotating rod 21, the rotating ring 20 is driven to rotate around the center of the eccentric disc 17. At this time, the rotation axis of the rotating ring 20 deviates from the rotating shaft 19 and always remains parallel to the rotating shaft 19, so that the scraping groove 18 fixedly connected to the second connecting rod 24 always remains horizontal, so that the scraping groove 18 can scrape the thick oil stains and impurities in the sewage tank 10 from the water.

[0033] After the impurities in the scraping groove 18 are removed, start the water pump 14. Through the water pump 14, the treated water is transported from the sewage tank 10 into the water outlet pipe 15. The water is sprayed from the water outlet pipe 15 into the groove of the scraping groove 18, and the viscous oil stains and particles in the scraping groove 18 are flushed into the storage groove 16, completing the cleaning of the scraping groove 18 and the collection of oil stains and sewage particles. And through the first filter plate 27 fixedly connected in the storage groove 16, the impurities in the water are filtered in the storage groove 16, and the water can be reused, so as to complete the interception and treatment of the sewage in the sewage tank 10.
