[0023] See also Figure 1 - Figure 5As shown, a screen machine for sewage treatment includes a device body 1 and rake teeth 20; a cleaning mechanism is arranged inside the device body 1, and the cleaning mechanism includes a rotating rod 21, and a plurality of sleeves 28 are welded and fixed on the rotating rod 21, and a spring 36 is fixedly connected inside the sleeve 28, and the spring 36 is fixedly connected to a round block 34, and the size of the round block 34 is adapted to the inside of the sleeve 28 so that the round block 34 can slide on the left side inside the sleeve 28, and a telescopic rod 27 and a fixed rod 28 are welded and fixed on the side of the round block 34 away from the spring 36. A fixed ring 32 is used to seal the sleeve 28. A plurality of groups of bristles 29 are glued and fixed on the left and right sides of the telescopic rod 27. A scraper block 30 is glued and fixed on the inner wall of the fixed ring 32. The scraper block 30 is close to the surface of the telescopic rod 27. The left side of the rotating rod 21 is rotatably connected to the inner wall of the device body 1. The right side of the rotating rod 21 is fixedly connected to the motor 22. A fixed block 24 is welded and fixed inside the device body 1. A semicircular groove 25 is opened at the bottom end of the fixed block 24. A protective shell 40 is sleeved on the motor 22.

[0024] During operation, in the process of intercepting floating objects on the surface of sewage, some floating objects will inevitably hang on the cleaning parts of the screen machine for sewage treatment in the above technology. In the long-term use, it will inevitably affect the normal operation of the screen machine and increase the difficulty of subsequent cleaning. Through the structural design of the cleaning mechanism, the function of scraping the floating objects on the rake teeth 20 when the rake teeth 20 run to the top is realized. When the floating objects on the rake teeth 20 are to be scraped, first, when the rake teeth 20 run to the top of the entire device, the rotating rod 21 drives the sleeve 28 and the telescopic rod 27 to rotate. The multiple groups of telescopic rods 27 are arranged between two adjacent groups of rake teeth 20. Therefore, the rake teeth 20 can be scraped by the bristles 29 on the left and right sides of the telescopic rod 27. When the rake teeth 20 are cleaned, some floating objects can be prevented from hanging on the rake teeth 20. The protective shell 40 on the motor 22 is used to provide protection for the motor 22, and a heat dissipation groove is also provided in the protective shell 40 to facilitate the normal heat dissipation of the motor 22.

[0025] Through the structural design of the fixed block 24 and the semicircular groove 25, when the rotating rod 21 rotates, the cushion block 37 will abut against the inner wall of the semicircular groove 25 to push the telescopic rod 27 to move inside the sleeve 28, so that the scraper block 30 can squeeze the bristles 29 on the telescopic rod 27, thereby cleaning up the debris on the bristles 29 to keep the bristles 29 clean. As the rotating rod 21 continues to rotate, the telescopic rod 27 will abut against the semicircular groove 25. The diameter of the semicircular groove 25 is the same as the length of the sleeve 28. The telescopic rod 27 will gradually move into the interior of the sleeve 28. During the movement of the telescopic rod 27, the multiple groups of bristles 29 on the telescopic rod 27 will contact the scraper block 30 and clean up the debris on the bristles 29 through the squeezing of the scraper block 30 to keep the bristles 29 clean. When the telescopic rod 27 no longer abuts against the inner wall of the semicircular groove 25, the telescopic rod 27 will be automatically ejected under the action of the spring 36 to facilitate the next scraping operation.

[0026] Furthermore, a slide groove 35 is provided on the top and bottom of the sleeve 28. The slide groove 35 is designed in a long rectangular shape. A slider 33 is slidably connected inside the slide groove 35. The slider 33 is designed in a rectangular shape and matches the size of the slide groove 35. The slider 33 is welded and fixed on the round block 34.

[0027] During operation, the slider 33 contacts the inner wall of the slide groove 35 , so that when the round block 34 slides inside the sleeve 28 , the movement of the round block 34 can be limited by the sliding of the slider 33 on the slide groove 35 , thereby ensuring the normal movement of the round block 34 .

[0028] Furthermore, a plurality of baffles 31 are glued and fixed on the inner wall of the fixing ring 32, and the baffles 31 are in contact with the scraper block 30;

[0029] During operation, the scraper block 30 and the baffle 31 are both made of plastic material and the baffle 31 is in contact with the scraper block 30 . The baffle 31 is used to support and fix the scraper block 30 so that the scraper block 30 can squeeze the bristles 29 .

[0030] Furthermore, the inner wall of the scraper block 30 is in contact with the sealing ring 39, and the sealing ring 39 is welded and fixed on the telescopic rod 27;

[0031] During operation, when the telescopic rod 27 is not in contact with the semicircular groove 25 , the sealing ring 39 will contact the inner wall of the scraper block 30 , thereby preventing smaller debris from entering the interior of the sleeve 28 .

[0032] Furthermore, a pad 37 is glued and connected to one side of the telescopic rod 27 away from the round block 34, and the pad 37 is made of rubber.

[0033] During operation, the cushion block 37 is made of rubber material, so that when the telescopic rod 27 abuts against the inner wall of the semicircular groove 25 , it can be used to provide a buffer between the telescopic rod 27 and the inner wall of the semicircular groove 25 .

[0034] Furthermore, a rotating block 38 is welded and fixed to the left side of the rotating rod 21, and the rotating block 38 passes through the left side of the device body 1;

[0035] During operation, a rotating block 38 is fixedly connected to the left side of the rotating rod 21 , and the rotation of the left side of the rotating rod 21 on the device body 1 is achieved through the shape and structure of the rotating block 38 .

[0036] Working principle: In the process of intercepting floating objects on the surface of sewage, some floating objects will inevitably hang on the cleaning parts of the screen machine in the above-mentioned technology. In the long-term use, it will inevitably affect the normal operation of the screen machine and increase the difficulty of subsequent cleaning. Through the structural design of the cleaning mechanism, the function of scraping the floating objects on the rake teeth 20 when the rake teeth 20 run to the top is realized. When the floating objects on the rake teeth 20 are to be scraped, first, when the rake teeth 20 run to the top of the entire device, the rotating rod 21 drives the sleeve 28 and the telescopic rod 27 to rotate. Multiple groups of telescopic rods 27 are arranged between two adjacent groups of rake teeth 20. Therefore, the rake teeth 20 can be scraped by the bristles 29 on the left and right sides of the telescopic rod 27. When the rake teeth 20 are cleaned, some floating objects can be prevented from hanging on the rake teeth 20. The protective shell 40 on the motor 22 is used to provide protection for the motor 22, and a heat dissipation groove is also provided in the protective shell 40 to facilitate the normal heat dissipation of the motor 22.

[0037] Through the structural design of the fixed block 24 and the semicircular groove 25, when the rotating rod 21 rotates, the cushion block 37 will abut against the inner wall of the semicircular groove 25 to push the telescopic rod 27 to move inside the sleeve 28, so that the scraper block 30 can squeeze the bristles 29 on the telescopic rod 27, thereby cleaning up the debris on the bristles 29 to keep the bristles 29 clean. As the rotating rod 21 continues to rotate, the telescopic rod 27 will abut against the semicircular groove 25. The diameter of the semicircular groove 25 is the same as the length of the sleeve 28. The telescopic rod 27 will gradually move into the interior of the sleeve 28. During the movement of the telescopic rod 27, the multiple groups of bristles 29 on the telescopic rod 27 will contact the scraper block 30 and clean up the debris on the bristles 29 through the squeezing of the scraper block 30 to keep the bristles 29 clean. When the telescopic rod 27 no longer abuts against the inner wall of the semicircular groove 25, the telescopic rod 27 will be automatically ejected under the action of the spring 36 to facilitate the next scraping operation.
