DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: Referring to the attached Figures 1-4 description, an environment-friendly sewage treatment and recycling device of the present utility model includes a main body of the device 1. For details, see Figure 2 , a water inlet 2 is fixedly installed at the top of the main body of the device 1, a filter screen 3 is fixedly installed inside the main body of the device 1, a collection box 4 is arranged at the bottom of the filter screen 3, and the collection box 4 is arranged inside the main body of the device 1. For details, see Figure 3A liquid tank 5 is fixedly installed inside the device body 1, a one-way valve 6 is fixedly connected to the top of the liquid tank 5, an air hole 7 is opened on the top of the liquid tank 5, a connector 8 is plugged into the inside of the liquid tank 5, one end of the connector 8 is fixedly connected to a piston plate 9, the piston plate 9 is slidably connected to the inside of the liquid tank 5, a spring 10 is fixedly installed on the top of the piston plate 9, and the spring 10 is fixedly installed inside the liquid tank 5;

[0023] The bottom of the liquid tank 5 is connected with a connecting pipe 11, one end of the connecting pipe 11 is connected with a piston cylinder 12, the piston cylinder 12 is fixedly installed inside the device body 1, the piston cylinder 12 is slidably connected with a piston rod 13 inside, one end of the piston rod 13 is fixedly connected with a scraper 14, and the scraper 14 is arranged on the top of the filter screen 3, see Figure 2 The top of the connector 8 is fixedly connected with a baffle 15, which is arranged at the bottom of the water inlet 2. Figure 4 The piston cylinder 12 is slidably connected to a piston block 16, which is fixedly connected to one end of the piston rod 13. A treatment agent box 17 is fixedly installed inside the device body 1. The bottom of the treatment agent box 17 is connected to a connecting pipe 18, and a toothed valve 19 is fixedly installed on the outer wall of the connecting pipe 18. The bottom of the connecting pipe 18 is connected to a drain pipe 20, which is fixedly installed inside the device body 1. The drain pipe 20 is rotatably connected to a rotating plate 21, and a counterweight 22 is provided on one side of the rotating plate 21. The counterweight 22 is slidably connected to the inside of the drain pipe 20, and a rack 23 is fixedly connected to the outer wall of the counterweight 22, which meshes with one side of the toothed valve 19.

[0024] It should be noted that, when the device is needed to process and recycle sewage, the sewage is first discharged into the water inlet 2 through the external pipe, so that the sewage enters the water inlet 2 to squeeze the baffle 15 downward, and then the baffle 15 drives the connecting member 8 to descend along the inside of the device body 1, so that the connecting member 8 squeezes the piston plate 9 to slide along the inside of the liquid tank 5, so that the piston plate 9 pulls the spring 10 to extend and discharges the liquid inside the liquid tank 5 into the inside of the piston cylinder 12 through the connecting pipe 11, so that the liquid pushes the piston block 16 along the piston cylinder 1 2 slides to the end, the piston cylinder 12 slides and drives the scraper 14 to move through the piston rod 13, so that the scraper 14 moves in the direction of the piston cylinder 12. When the piston plate 9 is squeezed to the bottom of the liquid tank 5, the scraper 14 fits the inner wall of the device body 1, and the baffle 15 is separated from the inside of the water inlet 2 to stop blocking the sewage, so that the sewage can fall to the top of the filter 3, and then the filter 3 filters the impurities in the sewage, so that the sewage and the impurities are separated, and the sewage is discharged into the inside of the drain pipe 20, and the impurities are accumulated on the filter 3;

[0025] Further, when the sewage discharge into the interior of the device body 1 stops, the baffle 15 will lose the impact of the sewage, causing the spring 10 to start pulling the piston plate 9 to slide upward along the interior of the liquid tank 5. As a result, the piston plate 9 withdraws the liquid inside the piston cylinder 12 through the connecting pipe 11 and slowly discharges the gas that was drawn into the liquid tank 5 through the one-way valve 6 during the previous descent through the air hole 7. As the liquid inside the piston cylinder 12 disengages, the piston block 16 will be adsorbed and slide back to its original position along the interior of the piston cylinder 12, causing the piston block 16 to push the scraper 14 to slide along the top of the filter screen 3, pushing all the impurities accumulated on the top of the filter screen 3 into the interior of the collection box 4, achieving the effect of automatically cleaning the impurities accumulated on the filter screen 3 without an external power source to control the operation of the device, making the device more energy-efficient and environmentally friendly. It should be noted that the setting of slowly discharging the gas drawn into the interior of the liquid tank 5 through the air hole 7 reduces the speed at which the connecting member 8 drives the baffle 15 to re-insert into the water inlet 2, reduces the speed at which the piston cylinder 12 is adsorbed and moves back to its original position by the liquid, and reduces the speed at which the scraper 14 cleans the impurities on the filter screen 3, allowing the residual sewage inside the water inlet 2 to fall onto the filter screen 3, allowing the residual sewage on the filter screen 3 to be filtered, and then the scraper 14 scrapes the impurities accumulated on the filter screen 3 to prevent the scraper 14 from pushing the sewage into the interior of the collection box 4;

[0026] Further, after the sewage enters the interior of the drain pipe 20, it will flow out of the device along the drain pipe 20. During the process of the sewage flowing along the drain pipe 20, the sewage will push the rotating plate 21 to rotate and stop sealing the interior of the drain pipe 20, and the rotating plate 21 will push the counterweight 22 to rise. The rise of the counterweight 22 will drive the toothed valve 19 to rotate and open through the rack 23, allowing the treatment agent inside the treatment agent tank 17 to be discharged into the interior of the drain pipe 20 through the connecting pipe 18 and mix with the sewage inside the drain pipe 20 to treat the sewage, causing a chemical reaction between the treatment agent and the sewage to convert the harmful substances in the sewage into harmless or valuable products, facilitating the subsequent treatment and recycling of the sewage, so as to achieve the effects of sewage treatment and resource recovery. It should be noted that the degree of rotation of the rotating plate 21 is determined by the amount of sewage flowing through the interior of the drain pipe 20. Eventually, the size of the rotation of the toothed valve 19 driven by the rack 23 is positively correlated with the flow rate of the sewage, so that when the amount of sewage passing through the drain pipe 20 is large, the amount of treatment agent discharged from the treatment agent tank 17 through the connecting pipe 18 increases, ensuring that the ratio of the treatment agent to the sewage does not change, facilitating the uniform mixing of the sewage and the treatment agent, and preventing the concentration of the treatment agent in some sewage from being too high or too low, which may affect the treatment of the sewage.
