1-3, the present utility model provides a technical solution: a sewage slag removal device, which includes a waste residue collection box 1, the right end of the upper wall of the waste residue collection box 1 is provided with a collection port 2, and the left end of the upper wall surface of the waste residue collection box 1 is provided The electric cylinder 3 is assembled, the right end of the piston rod 4 of the electric cylinder 3 is equipped with a scraper 5, the piston rod 4 is rotatably connected with the scraper 5, and an electric push rod 6 is installed on the upper end of the piston rod 4 near the electric cylinder 3 side, and the electric push rod 6 The telescopic end is connected with a connecting rod 7, the connecting rod 7 is rotatably connected with the scraper 5 at the end away from the electric push rod 6, the piston rod 4 is fixedly sleeved with a sealing plate 8, the connecting rod 7 penetrates the sealing plate 8, and the connecting rod 7 is connected with the sealing plate 8. The plate 8 is slidably connected, the right side of the waste residue collection box 1 is equipped with a filter device 9, and the power input ends of the electric cylinder 3 and the electric push rod 6 are respectively connected to an external power source.

In the initial state, the scraper 5 is located on the right side of the filter box 91. When the filter screen 94 needs to be cleaned, the electric cylinder 3 drives the scraper 5 to move leftward in the filter box 91 through the piston rod 4, and the scraper 5 cleans the filter screen 94. The scraper is formed, and the slag is pushed to the collection port 2 and then dropped into the waste slag collection box 1. After completing one scraping, the electric cylinder 3 drives the scraper 5 to move to the right through the piston rod 4. The rod 6 pushes the connecting rod 7 to extend to the right, so that the scraper 5 is inclined to prevent the waste residue remaining on the filter screen 94 from being scraped to the right end of the inner cavity of the filter box 91 when the scraper 5 moves to the right, which is easy to cause the filter box for a long time. There is too much waste residue at the right end of 91, resulting in incomplete scraping and affecting the filtering effect. When the scraper 5 moves to the left, the connecting rod 7 is pulled by the electric push rod 6, and the connecting rod 7 makes the scraper 5 and the filter screen 94 vertical.
