[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5 The utility model provides a technical solution: a sewage treatment device that can be automatically cleaned, including: an installation box 1, a support frame 2, a water inlet 3, a filter cartridge 4, a protective cover 5, a collecting plate 6, a first bevel gear 7, a second bevel gear 8, a third bevel gear 9, a connecting shaft 10, a brush plate 11, a filter bucket 12, a collecting box 13, an activated carbon filter plate 14, a water outlet 15, a gear 16, a gear ring 17, a drive disc 18, a connecting plate 19, a limit block 20, a protrusion 21 and a spring 22.

[0030] When using the self-cleaning sewage treatment device, first Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the water inlet 3 is fixedly mounted on the upper end of the mounting box 1, and a protective cover 5 is provided below the water inlet 3, and the protective cover 5 is fixedly connected to the upper end of the filter cartridge 4, the upper end of the filter cartridge 4 is rotatably connected to the upper wall of the mounting box 1, and the middle upper end of the filter cartridge 4 is fixedly connected to the third bevel gear 9, and the inner sides of the filter cartridge 4 and the third bevel gear 9 are rotatably connected with a connecting shaft 10, the upper end of the connecting shaft 10 is fixedly connected to the second bevel gear 8, and a brush plate 11 is fixedly mounted on the outer side of the connecting shaft 10, the first bevel gear 7 is meshed and connected between the second bevel gear 8 and the third bevel gear 9, and the left end of the first bevel gear 7 is fixedly connected to the output end of the motor, the brush plate 11 rotates and slides on the inner side of the filter cartridge 4, and the rotation direction of the brush plate 11 is opposite to that of the filter cartridge 4, and the lower end of the filter cartridge 4 is connected to the collecting plate 6 by bolts;

[0031] Connect the sewage pipe to the water inlet 3 so that the sewage enters the interior of the filter cartridge 4. The protective cover 5 can prevent the sewage from splashing out of the outside of the filter cartridge 4. Turn on the motor connected to the first bevel gear 7 so that the first bevel gear 7 drives the second bevel gear 8 and the third bevel gear 9 to rotate. The second bevel gear 8 drives the connecting shaft 10 and the brush plate 11 to rotate. The third bevel gear 9 drives the filter cartridge 4 to rotate. The centrifugal force and the stirring of the brush plate 11 are used to accelerate the discharge of sewage. The solid impurities in the sewage are intercepted and retained in the interior of the filter cartridge 4. The bristles of the brush plate 11 clean and remove the silt adhering to the inner wall of the filter cartridge 4, thereby exerting the automatic cleaning function, simplifying the cleaning process, and preventing the filter cartridge 4 from being blocked and affecting the drainage effect.

[0032] A filter hopper 12 is installed directly below the filter cartridge 4, and the filter hopper 12 is fixed to the installation box 1, and the lower end of the filter hopper 12 is slidably connected to a collection box 13. The filter hopper 12 is provided at two locations, and the filter hole radius of the filter hopper 12 decreases from top to bottom. A filter screen is provided at the lower end of the collection box 13, and the filter hole radius of the collection box 13 is the same as that of the filter hopper 12 connected thereto. An activated carbon filter plate 14 is installed below the filter hopper 12, and the activated carbon filter plate 14 is slidably connected to the installation box 1. A water outlet 15 is installed below the activated carbon filter plate 14, and the water outlet 15 is fixed to the installation box 1;

[0033] The sewage filtered out from the inside of the filter cartridge 4 enters the inside of the filter bucket 12. Because the filter bucket 12 is tilted downward from the outside to the inside, it is convenient to flush solid debris into the inside of the collection box 13 without affecting the filtering effect, and the filter bucket 12 is not easy to be blocked. The sewage passes through the two filter buckets 12 in sequence, gradually filtering out the objects and debris and leaving them in the collection box 13. Then the sewage passes through the activated carbon filter plate 14 to remove the odor. Finally, the sewage is discharged from the outlet 15, waiting for the next step to remove harmful substances such as pathogens, heavy metals and pesticides in the sewage.

[0034] like Figure 1 、 Figure 3 and Figure 5 As shown, the upper end of the gear 16 is fixedly connected to the output end of the motor, and the left side of the gear 16 is meshed with a gear ring 17, and the lower end of the gear ring 17 is fixedly connected to the drive disk 18, the drive disk 18 is rotatably connected to the installation box 1, and the lower end of the drive disk 18 is meshed with a connecting plate 19, the connecting plate 19 is arranged at equal angles along the center point of the filter cartridge 4, and the connecting plate 19 is slidably connected to the outside of the limit block 20, and the limit block 20 is fixed to the installation box 1, the protrusion 21 is connected to the connecting plate 19 by a spring 22, and the protrusion 21 is slidably connected to the inner sides of the filter cartridge 4 and the connecting plate 19 respectively;

[0035] Turn on the motor to rotate the gear 16, which meshes with the gear ring 17. The gear ring 17 then drives the drive disc 18 to rotate synchronously. The drive disc 18 in turn drives the connecting plate 19 to move toward the filter cartridge 4 until the connecting plate 19 reaches the innermost side. At this time, the rotating filter cartridge 4 intermittently squeezes the protrusion 21, causing the protrusion 21 to move toward the connecting plate 19. At this time, the protrusion 21 squeezes the spring 22 to elastically deform. When the spring 22 recovers its elastic deformation, it pushes the protrusion 21 to slide into the filter hole of the filter cartridge 4, removing the debris clogged in the filter hole. Cooperating with the brush plate 11, the filter cartridge 4 is automatically cleaned to prevent it from being clogged by sand and gravel and other debris, thereby extending the usable time of the device.
