[0034] Referring to Figure 6As shown in the figure, in this embodiment: The auxiliary structure 4 includes a storage box 41, which is placed on the inner wall of the sedimentation tank 1. The two sides of the storage box 41 are respectively attached to the two sides of the inner wall of the sedimentation tank 1. One side of the storage box 41 is fixedly connected with a handle 42. The side of the storage box 41 away from the handle 42 is attached to the stepped platform 301. A baffle 46 is attached to the side of the storage box 41 close to the handle 42. A connection hole 43 is opened on one side of the sedimentation tank 1.

By setting the auxiliary structure 4, personnel can conveniently limit the storage box 41, so that the storage box 41 can collect the sludge scraped by the scraping plate 307. When the collection is completed, personnel can conveniently uniformly process the sludge. One side of the sedimentation tank 1 is fixedly connected with an auxiliary platform 49.

During the process of the sliding rod 45 driving the baffle 46 to move, the guiding rod 48 can guide and position the baffle 46, thereby avoiding rotational deviation during the movement of the baffle 46.

[0035] Detailed description of the usage method: In the present invention, when it is necessary to use the sludge removal device to clean the sludge in the sedimentation tank 1, first start the servo motor 309 to drive the lead screw 304 to rotate. The lead screw 304 drives the fixed seat 303 to slide along the inner wall of the sliding hole 302. The fixed seat 303 drives the connecting plate 306 and the scraping plate 307, so that the scraping plate 307 moves along the inclined waist side of the stepped platform 301 under the drive of the torsion spring 312. Furthermore, the sludge on the inclined waist side of the stepped platform 301 can be scraped by means of the scraping plate 307. When the scraping plate 307 moves to the upper surface position of the stepped platform 301, the scraping plate 307 will continue to be attached to the upper surface of the stepped platform 301 due to the drive of the torsion spring 312 and its own gravity until the scraping plate 307 scrapes the sludge out of the stepped platform 301. When the sludge cleaning is completed, personnel only need to start the servo motor 309 to drive the lead screw 304 to rotate in the reverse direction until the scraping plate 307 returns to the original position, and the sludge cleaning operation can be completed. Among them, the first protective sleeve 310 and the second anti-slip sleeve can seal and block the sliding hole 302, thereby preventing sludge from accumulating on the inner wall of the sliding hole 302. In addition, the torsion spring 312 can drive the scraping plate 307 to abut against the side surface of the stepped platform 301, thereby improving the stability of the scraping plate 307 during the process of cleaning sludge.

[0036] In the present utility model, when it is necessary to use the storage box 41 to store the silt scraped by the scraper 307, first pull the baffle 46 into the connection hole 43, and then move the handle 42 to push the storage box 41, so that the storage box 41 enters the inner wall of the sedimentation tank 1 along the auxiliary table 49. When one side of the storage box 41 fits against the stepped platform 301, release the slide rod 45. At this time, the spring 47 will drive the slide rod 45 and the baffle 46 to move towards the storage box 41. When one side of the baffle 46 fits against the storage box 41, the limiting of the storage box 41 can be completed. At this time, the silt scraped by the scraper 307 will fall into the storage box 41 along the upper surface of the stepped platform 301. After the silt is removed, pull the slide rod 45 to drive the baffle 46 to separate from the storage box 41, and then pull the handle 42 to drive the storage box 41 to be withdrawn from the sedimentation tank, so that the silt can be centrally recycled. Among them, by arranging the auxiliary table 49 on one side of the sedimentation tank 1 and rounding one side of the auxiliary table 49, the storage box 41 can be conveniently pushed into the sedimentation tank 1. In addition, during the process of the slide rod 45 driving the baffle 46 to move, the guide rod 48 can guide and position the baffle 46, thereby preventing the baffle 46 from rotating and deviating during the moving process.
