[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 the embodiments. It should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "setting" should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific situations.

[0021] Refer to Figures 1 - 3 , a sludge solid waste debris separation device, including a box body 1, a filter box 12 is rotatably connected between the inner walls on both sides of the box body 1, the filter box 12 is inclined, a through collection box 11 is inserted on one side of the box body 1, the collection box 11 is located below the filter box 12 for collecting impurities, and the bottom of the collection box 11 is also provided with leakage holes with the same aperture as that of the filter box 12. A through discharge tube 2 is rotatably connected to one side of the box body 1, a material dropping opening 18 for feeding is arranged at the top of the discharge tube 2, guide plates 19 for guiding sludge are installed on the inner walls on both sides of the box body 1, the guide plates 19 are inclined and the bottom is fixed to the material dropping opening 18. One end of the discharge tube 2 is rotatably connected with a through driving shaft 7, a spiral blade 8 for feeding is fixedly connected to the circumference of the driving shaft 7, a filter cylinder 4 for secondary filtration is inserted into one end of the discharge tube 2, the filter hole diameter of the filter cylinder 4 is smaller than the filter hole diameter of the filter box 12, a motor 6 is fixedly connected to the outer wall of one side of the box body 1, and one end of the output shaft of the motor 6 is fixed to the driving shaft 7.

[0022] In the present utility model, a driving disc 16 is fixedly connected to the circumference of the output shaft of the motor 6, a protrusion 17 is fixedly connected to the circumference of the driving disc 16, a guide block 14 is fixedly connected to the outer wall of one side of the box body 1, a through slide bar 15 is slidably connected to the top of the guide block 14, the slide bar 15 is T-shaped and the bottom contacts the driving disc 16. A cross bar 13 for cooperating with the slide bar 15 is fixedly connected to one side of the filter box 12. The driving disc 16 jacks up the slide bar 15 through the protrusion 17, the slide bar 15 jacks up through the cross bar 13, and then the filter box 12 resets under its own weight, so as to reciprocate and accelerate the feeding speed.

[0023] Particularly, a roller is rotatably connected to the bottom of the slide bar 15, and the friction between the slide bar 15 and the driving disc 16 is reduced through the roller, which facilitates the movement of the slide bar 15.

[0024] In the present utility model, two fixed rods 9 are fixedly connected to the circumference of the drive shaft 7, and a scraper 10 for cleaning the filter cartridge 4 is fixedly connected between the two fixed rods 9. The scraper 10 is in contact with the inner wall of the filter cartridge 4. When the drive shaft 7 rotates, it drives the scraper 10 to clean the inner wall of the filter cartridge 4, thereby improving the filtering effect of the filter cartridge 4.

[0025] It should be noted that two threaded rods 3 are fixedly connected to the outer wall of one side of the box body 1. The threaded rods 3 penetrate through the filter cartridge 4, and nuts 5 for fixing the filter cartridge 4 are threadedly connected to the circumferences of the threaded rods 3. When the impurities in the filter cartridge 4 are too much and need to be cleaned, loosen the nuts 5, then replace the filter cartridge 4 with a new one, and clean the replaced filter cartridge 4.

[0026] In particular, the scraper 10 is made of rubber.

[0027] Working principle: When in use, start the motor 6, and then inject the sludge above the filter box 12. The larger solid impurities in the sludge are filtered out through the filter box 12, reducing the subsequent filtering difficulty and the number of times of cleaning the filter screen. Subsequently, the sludge enters the discharge tube 2 after being guided by the guide plate 19. The motor 6 drives the spiral blade 8 to rotate through the drive shaft 7, and then pushes the sludge into the filter cartridge 4 for secondary filtering, and then discharges it. When the drive shaft 7 rotates, it drives the scraper 10 to clean the inner wall of the filter cartridge 4, thereby improving the filtering effect of the filter cartridge 4. When the impurities in the filter cartridge 4 are too much and need to be cleaned, loosen the nuts 5, then replace the filter cartridge 4 with a new one, and clean the replaced filter cartridge 4;

[0028] When the motor 6 starts, it also drives the drive disk 16 to rotate. The drive disk 16 pushes up the slide bar 15 through the convex block 17, and the slide bar 15 is pushed up through the cross bar 13. Subsequently, the filter box 12 resets under its own weight, and reciprocating activities like this accelerate the feeding speed.

[0029] In this application, the structures and connection relationships not described in detail are all prior arts, and their structures and principles are already well-known technologies, so they will not be elaborated here.

[0030] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its utility model concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
