[0022] 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 the embodiments.

[0023] Reference Figures 1-4 A multi-stage filtration sewage recycling device includes a shell 1. Upper arc blocks 2 are welded to the inner walls of both sides of the shell 1. An upper rotating shaft 3 is rotatably inserted between the inner walls of both sides of the shell 1. The outer wall of the upper rotating shaft 3 is fixedly sleeved with a rotating plate 4 with a diversion function. The upper rotating shaft 3 rotates under the drive of the motor, thereby driving the rotating plate 4 to rotate, thereby changing the inclination direction of the rotating plate 4, thereby adjusting the flow direction of the sewage. The two ends of the rotating plate 4 are respectively in contact with the two upper arc blocks 2. A single-head sealed pipe 12 is fixedly inserted on one side of the shell 1. The single-head sealed pipe 12 Located below the rotating plate 4, a plurality of high-pressure nozzles 13 are clamped to the outer wall of the single-end sealed tube 12. A water tank 19 is fixed to the outer wall of one side of the shell 1 by bolts. A pump body 20 is fixed to the outer wall of one side of the water tank 19 by bolts. The water inlet end of the pump body 20 is plugged into the water tank 19 through a connecting pipe, and the water outlet end of the pump body 20 is connected to the single-end sealed tube 12 through a connecting pipe. Under the action of the pump body 20, the water in the water tank 19 is pumped into the single-end sealed tube 12 and then sprayed out from the high-pressure nozzle 13 to rinse the impurities attached to the surface of the filter 9 and the activated carbon plate 10;

[0024] A partition plate 5 is welded between the inner walls on both sides of the shell 1, thereby dividing the lower part of the shell 1 into two independent spaces. The bottom end of the partition plate 5 is fixedly connected to the bottom inner wall of the shell 1. Two lower rotating shafts 7 are rotatably inserted between the inner walls on both sides of the shell 1 and located below the single-head sealing tube 12. The outer wall of the lower rotating shaft 7 is fixedly sleeved with a rotating frame 8, which is driven by the rotation of the lower rotating shaft 7 to rotate, thereby comprehensively cleaning the sewage. A multi-layer filter screen 9 is clamped on the top of the rotating frame 8, which filters the impurity particles in the sewage through the multi-layer filter screen 9. An activated carbon plate 10 is clamped on the bottom of the rotating frame 8, which removes organic pollutants, heavy metals, etc. in the sewage. Side covers 18 are clamped on both sides of the shell 1. When the activated carbon plate 10 needs to be replaced, the side cover 18 is opened to replace the activated carbon plate 10. A lower arc block 11 is welded on one side of the side cover 18 and on both sides of the partition plate 5. One end of the rotating frame 8 is in contact with the lower arc block 11, and two bottom covers 6 are clamped on the bottom of the shell 1.

[0025] A plurality of ultraviolet sterilization lamps 14 are fixed between the inner walls on both sides of the shell 1 by bolts, and the sewage is sterilized by the ultraviolet sterilization lamps 14. The ultraviolet sterilization lamps 14 are located below the rotating frame 8. The water outlet of the shell 1 is connected to the lower valve body 15 through a flange. When the lower valve body 15 is opened, the treated sewage is discharged from the lower valve body 15. Two pointed covers 16 are fixed between the inner walls on both sides of the shell 1 by bolts. The pointed covers 16 cover the top of the single-head sealed tube 12, thereby preventing sewage from falling on the single-head sealed tube 12 to avoid corrosion of the single-head sealed tube 12. Limiting inclined plates 17 are welded to the inner walls on both sides of the shell 1. The limiting inclined plates 17 limit the rotation of the rotating plate 4. The single-head sealed tube 12 is provided with an upper valve body 21. A plurality of motors are fixed to the outer wall of one side of the shell 1 by bolts. The output ends of the plurality of motors are fixedly connected to the two lower rotating shafts 7 and one end of the upper rotating shaft 3 respectively.

[0026] The working principle of this embodiment is as follows: when in use, sewage is first placed into the housing 1. Then, under the guidance of the rotating plate 4, the sewage falls on the filter screen 9 on the right side of the partition plate 5, thereby filtering the impurity particles in the sewage through the multi-layer filter screen 9. Then, the activated carbon plate 10 removes organic pollutants, heavy metals, etc. in the sewage. Then, the filtered sewage falls to the bottom of the housing 1, and is sterilized by the ultraviolet sterilization lamp 14 for 1 hour. After that, the lower valve body 15 on the right side of the housing 1 is opened and the sewage is discharged from the lower valve body 15.

[0027] When it is necessary to clean the filter screen 9 on the right side of the partition plate 5, open the bottom cover 6 on the bottom right side of the shell 1, and the upper rotating shaft 3 is rotated under the drive of the motor, thereby driving the rotating plate 4 to rotate, thereby changing the inclination direction of the rotating plate 4, and then the sewage falls along the rotating plate 4 onto the filter screen 9 on the left side of the partition plate 5, and continues to treat the sewage. Next, open the upper valve body 21, and under the action of the pump body 20, the water in the water tank 19 is pumped into the single-head sealed tube 12, and then sprayed out from the high-pressure nozzle 13 to flush the impurities attached to the surface of the filter screen 9 and the activated carbon plate 10. At the same time, the lower rotating shaft 7 is driven by the motor to rotate, thereby driving the rotating frame 8 and the filter screen 9 and the activated carbon plate 10 thereon to rotate, thereby comprehensively cleaning the filter screen 9 and the activated carbon plate 10.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
