The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] Please seeFigures 1-4 This utility model provides a technical solution: a wastewater recycling impurity filtration device, including a wastewater tank 1, a conical bucket 22 fixedly connected to the lower surface of the wastewater tank 1, an inlet 2 opened on the upper surface of the wastewater tank 1, a filter screen 3 installed inside the inlet 2, a pad box 4 fixedly connected to the upper surface of the wastewater tank 1, a motor 5 fixedly connected to the upper surface of the pad box 4, a first rotating shaft 6 fixedly connected to the output end of the motor 5, and a protective box 21 rotatably connected to the left end of the first rotating shaft 6;

[0027] The protective box 21 is equipped with a coaxial reversing structure, and the wastewater tank 1 is equipped with a rotating device.

[0028] Furthermore, the coaxial reversing structure includes a fixing frame 7, which is fixedly connected to the left end of the outer surface of the motor 5. The fixing frame 7 is rotatably sleeved with the first rotating shaft 6. A first bevel gear 8 is fixedly connected to the end of the first rotating shaft 6 away from the motor 5. A second bevel gear 9 and a third bevel gear 10 are meshed on the outer surface of the first bevel gear 8. A third rotating shaft 12 is fixedly connected to the lower end of the third bevel gear 10. The third rotating shaft 12 is rotatably sleeved with the fixing frame 7. A second rotating shaft 11 is fixedly sleeved inside the second bevel gear 9. The second rotating shaft 11 is rotatably sleeved with the fixing frame 7. The second rotating shaft 11 rotatably passes through the third rotating shaft 12.

[0029] Furthermore, the rotating device includes a fixed plate 14, which is fixedly sleeved on the outer surface of the third rotating shaft 12. A rotating cylinder 13 is fixedly connected to the lower end of the fixed plate 14. The rotating cylinder 13 is inside the wastewater tank 1, and a toothed disc 20 is provided at the bottom of the rotating cylinder 13.

[0030] The lower end of the second rotating shaft 11 is fixedly connected to the fourth rotating shaft 15. The outer surface of the fourth rotating shaft 15 is fixedly sleeved with the first support plate 16 and the second support plate 18. The second support plate 18 is below the first support plate 16. The front end of the first support plate 16 is fixedly connected to the strong alkali tank 17. The bottom of the strong alkali tank 17 has a small hole to facilitate the strong alkali in the strong alkali tank 17 to flow out and neutralize with the wastewater. The rear end of the second support plate 18 is fixedly connected to the carbon adsorption plate 19.

[0031] Furthermore, when using the device, the staff pours the wastewater into the wastewater tank 1 through the inlet 2. The filter screen 3 inside the inlet 2 filters out large-volume impurities and large-particle metals. The remaining small particles and small-volume impurities flow into the wastewater tank 1. The small particles and small-volume impurities enter the rotating drum 13 from the wastewater tank 1 and stand for a few minutes, so that the harmful substances in the wastewater are adsorbed on the carbon adsorption plate 19. At the same time, strong alkali flows out from the hole at the bottom of the strong alkali tank 17, adding strong alkali to the wastewater in the strong acid environment to neutralize it and adjust the pH value to about 8-9.

[0032] Then, the motor 5 is started. The output end of the motor 5 drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the first bevel gear 8 to rotate. The rotation of the first bevel gear 8 drives the second bevel gear 9 and the third bevel gear 10 to mesh. The rotation of the second bevel gear 9 drives the second rotating shaft 11 to rotate counterclockwise. The rotation of the second rotating shaft 11 drives the fourth rotating shaft 15 to rotate counterclockwise. The rotation of the fourth rotating shaft 15 drives the first support plate 16 and the second support plate 18 to rotate. This causes the first support plate 16 to drive the strong alkali tank 17 to rotate, so that all the strong alkali in the strong alkali tank 17 flows out from the hole at the bottom of the strong alkali tank 17. The rotation of the strong alkali tank 17 makes the strong alkali in the strong alkali tank 17 neutralize the acidic wastewater more thoroughly. At the same time, the rotation of the second support plate 18 drives the carbon adsorption plate 19 to rotate, so that the carbon adsorption plate 19 adsorbs the harmful substances in the wastewater while rotating. The rotation of the carbon adsorption plate 19 makes the carbon adsorption plate 19 adsorb the harmful substances in the wastewater more thoroughly.

[0033] Simultaneously, the rotation of the third bevel gear 10 drives the third rotating shaft 12 to rotate clockwise. The rotation of the third rotating shaft 12 drives the fixed plate 14 to rotate, and the rotation of the fixed plate 14 drives the rotating drum 13 to rotate clockwise. Under the action of centrifugal force, the wastewater in the rotating drum 13 causes solid impurity particles to separate from the liquid. The gap between the solid particles becomes smaller and smaller, so that the liquid is gradually discharged from the screen holes opened in the rotating drum 13 into the bottom of the wastewater tank 1. Only dry solid waste residue remains in the rotating drum 13. At this time, the water discharged into the wastewater tank 1 is discharged from the cone hopper 22 at the bottom of the wastewater tank 1. After the wastewater is discharged, the staff operates the control box to open the sawtooth disk 20 at the bottom of the rotating drum 13, so that the remaining solid waste residue in the rotating drum 13 falls into the cone hopper 22 through the sawtooth disk 20 and is then discharged from the cone hopper 22.

[0034] Working principle: The staff pours wastewater into the wastewater tank 1 through the inlet 2. The filter screen 3 inside the inlet 2 filters out large-volume impurities and large metal particles. The remaining small particles and small-volume impurities flow into the wastewater tank 1. The small particles and small-volume impurities enter the rotating drum 13 from the wastewater tank 1. After standing for a few minutes, the harmful substances in the wastewater are adsorbed on the carbon adsorption plate 19. At the same time, strong alkali flows out from the hole at the bottom of the strong alkali tank 17. The strong alkali tank 17 adds strong alkali to the wastewater in the strong acid environment to neutralize it and adjust the pH value to about 8-9.

[0035] Then, the motor 5 is started. The output end of the motor 5 drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the first bevel gear 8 to rotate. The rotation of the first bevel gear 8 drives the second bevel gear 9 and the third bevel gear 10 to mesh. The rotation of the second bevel gear 9 drives the second rotating shaft 11 to rotate counterclockwise. The rotation of the second rotating shaft 11 drives the fourth rotating shaft 15 to rotate counterclockwise. The rotation of the fourth rotating shaft 15 drives the first support plate 16 and the second support plate 18 to rotate. This causes the first support plate 16 to drive the strong alkali tank 17 to rotate, so that all the strong alkali in the strong alkali tank 17 flows out from the hole at the bottom of the strong alkali tank 17. The rotation of the strong alkali tank 17 makes the strong alkali in the strong alkali tank 17 neutralize the acidic wastewater more thoroughly. At the same time, the rotation of the second support plate 18 drives the carbon adsorption plate 19 to rotate, so that the carbon adsorption plate 19 adsorbs the harmful substances in the wastewater while rotating. The rotation of the carbon adsorption plate 19 makes the carbon adsorption plate 19 adsorb the harmful substances in the wastewater more thoroughly.

[0036] Simultaneously, the rotation of the third bevel gear 10 drives the third rotating shaft 12 to rotate clockwise. The rotation of the third rotating shaft 12 drives the fixed plate 14 to rotate, and the rotation of the fixed plate 14 drives the rotating drum 13 to rotate clockwise. Under the action of centrifugal force, the wastewater in the rotating drum 13 separates the solid impurity particles from the liquid. The gap between the solid particles becomes smaller and smaller, so that the liquid is gradually discharged into the wastewater tank 1 through the sieve holes opened in the rotating drum 13. Only dry solid waste residue is left in the rotating drum 13. At this time, the water discharged into the wastewater tank 1 is discharged through the cone hopper 22. After the wastewater is discharged, the staff operates the control box to open the sawtooth disk 20 at the bottom of the rotating drum 13, so that the remaining solid waste residue in the rotating drum 13 falls into the cone hopper 22 through the sawtooth disk 20 and is then discharged from the cone hopper 22.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
