[0030] It is worth pointing out that referring to Figure 5 A first slit 15, a second slit 16 and a third slit 17 are provided at the top of the driving cavity 5, and the first slit 15, the second slit 16 and the third slit 17 are respectively located above the rotating shaft gear 12, the feeding gear 13 and the reset gear 14. A first transmission gear 18 is provided in the first slit 15, and the first transmission gear 18 is meshed with the rotating shaft gear 12. A second transmission gear 19 is provided in the second slit 16, and the second transmission gear 19 is meshed with the feeding gear 13. A third transmission gear 20 is provided in the third slit 17, and a fourth transmission gear 21 is provided between the third transmission gear 20 and the reset gear 14. The fourth transmission gear 21 is fixed to the inner wall of the driving cavity 5 through a bracket, and the third transmission gear 20 is meshed with the fourth transmission gear 21, and the fourth transmission gear 21 is meshed with the reset gear 14.

[0031] Further, refer to Figure 2 and Figure 6A fixed circular plate 22 is arranged above the rotating base 3. The fixed circular plate 22 is connected to the top of the filter barrel 1 through a bracket. The fixed circular plate 22 is coaxially arranged with the rotating base 3. A driving gear ring 23, a feed rack 24 and a reset rack 25 are arranged on the lower surface of the fixed circular plate 22. The feed rack 24 and the reset rack 25 are both arc-shaped bar structures, and the driving gear ring 23, the feed rack 24 and the reset rack 25 are all coaxial with the fixed circular plate 22.

[0032] It should be noted that, refer to Figure 6 In this embodiment, the lower surface of the fixed circular plate 22 is counterclockwise evenly divided into a feeding area 26, a processing area 27, a pushing area 28 and a reset area 29. A liquid inlet 30 is provided on the top of the filter barrel 1. The liquid inlet 30 is connected to a liquid inlet pipe 31. The liquid inlet pipe 31 is located outside the feeding area 26. A slag outlet 11 is provided on the side wall of the filter barrel 1. The slag outlet 11 is opposite to the pushing area 28 and extends to the reset area 29. The feed rack 24 is located in the pushing area 28, and the reset rack 25 is located in the reset area 29. The driving gear ring 23 is meshed with the first transmission gear 18, the feed rack 24 corresponds to the second transmission gear 19, and the reset rack 25 corresponds to the third transmission gear 20.

[0033] It should also be noted that, referring to Figure 4 A plurality of inclined slideways 32 are arranged on the rotating base 3 . The inclined slideways 32 are arranged in an arc shape between adjacent filter tanks 4 , and the inclined slideways 32 are located below the liquid inlet pipe 31 .

[0034] The lower end of the rotating shaft 2 in this embodiment extends out of the filter barrel 1 and is connected to a motor. When the manganese-containing wastewater treatment system is working, the motor drives the rotating shaft 2 to rotate continuously.

[0035] When the manganese-containing wastewater treatment system is working, the manganese-containing wastewater flows in from the liquid inlet pipe 31, passes through the inclined slide 32 or directly flows into the filter tank 4, and the rotating shaft 2 drives the rotating base 3 to rotate, so that the driving gear ring 23 drives the first transmission gear 18 to rotate, and then the rotating shaft gear 12 and the rotating shaft 9 rotate, and the rotating shaft 9 drives the stirring blade 10 to rotate, thereby stirring the manganese-containing wastewater in the filter tank 4 and accelerating the filtration of the manganese-containing wastewater. After filtration, the waste residue in the manganese-containing wastewater remains in the filter tank 4.

[0036] Since the stirring blade 10 is provided, the filtration of manganese-containing wastewater can be accelerated. Therefore, when the filter tank 4 rotates to the pushing area 28, solid-liquid separation has been achieved. At this time, the feed rack 24 contacts and meshes with the second transmission gear 19. As the rotating base 3 rotates, the feed rack 24 drives the second transmission gear 19 to rotate, and the second transmission gear 19 drives the feed gear 13 to rotate. The feed gear 13 drives the nut seat sleeve 7 to rotate, so that the nut seat sleeve 7 moves along the axial direction of the driving screw 6, and then drives the rectangular frame 8 to move outward. Since the manganese-containing wastewater falls into the rectangular frame 8, the filtered waste residue is also in the rectangular frame 8. When the rectangular frame 8 moves outward, the waste residue also moves outward. When the rectangular frame 8 is moved out of the filter barrel 1 through the slag outlet 11, the waste residue in the rectangular frame 8 is also moved out of the filter barrel 1 and collected by the pre-placed collection barrel.

[0037] When the filter tank 4 rotates to the reset area 29, the reset rack 25 contacts and meshes with the third transmission gear 20, the third transmission gear 20 drives the fourth transmission gear 21 to rotate, and the fourth transmission gear 21 drives the reset gear 14 to rotate, thereby driving the nut seat sleeve 7 to rotate in the opposite direction, so that the nut seat sleeve 7 moves inward along the axial direction of the driving screw 6, that is, the rectangular frame 8 is reset.

[0038] In this way, the filter tank 4 rotates continuously, receives manganese-containing wastewater in the feed area 26, performs solid-liquid separation in the treatment area 27, and accelerates the solid-liquid separation by the rotation of the stirring blade 10, drives the waste residue to move out of the filter barrel 1 in the pushing area 28, and resets in the reset area 29 to receive manganese-containing wastewater again, and the cycle is repeated continuously. During the circulation process, the filtered waste residue is discharged in time, so that the filter tank 4 always has a better filtering capacity, and at the same time it is convenient for the operator to collect the waste residue.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0040] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
