when the invention is used by a worker, water is added into the water inlet channel 11 of the sedimentation tank through the water inlet pipe 12, and the water in the water inlet channel 11 is blocked by the channel wall and flows into the sedimentation tank smoothly; the mud scraper 2 is started, the mud scraper 2 drives the scraper 21 to move, when the scraper 21 moves to the surface of the water body, scum floating on the surface of the water body is pushed into the scum groove 15, and when the scraper 21 moves to the bottom of the sedimentation tank, the scraper 21 scrapes sludge accumulated at the bottom of the sedimentation tank to the sludge hopper 17; after sludge enters the sludge hopper 17, the motor 9 is started, the motor 9 drives the threaded rod 5 to rotate, at the moment, the threaded rod 5 converts the self rotary motion into the linear motion of the first sliding plate 4, so that the first sliding plate 4 moves to the middle position of the sludge hopper 17, and as the thread rotating direction on the threaded rod 5 is arranged from the middle part to the opposite ends, the first sliding plate 4 in sliding connection with the other side also synchronously moves to the middle position of the sludge hopper 17 when the threaded rod 5 rotates, and when the two first sliding plates 4 move close to each other, the sliding rod 6 can guide the first sliding plate 4 to keep the first sliding plate 4 stably moving all the time; finally, the two first sliding plates 4 which move close to each other push the sludge deposited on the bottom surface of the sludge hopper 17 to the position, close to the sludge suction pipe 3, in the sludge hopper 17, and the sludge near the pipe body is sucked out by the sludge suction pipe 3 and enters the next link of sludge treatment; when the first sliding plate 4 moves towards the middle of the sludge hopper 17, sludge at the bottom of the sludge hopper 17 can be scraped to a position near the sludge suction pipe 3 in the middle of the sludge hopper 17, meanwhile, the two first sliding plates 4 moving towards each other are mutually contacted, and the arranged semicircular grooves 41 are spliced together to form a whole circle which just wraps the outer wall of the sludge suction pipe 3;
then, when the first sliding plate 4 moves towards the middle of the sludge hopper 17, the first sliding plate 4 synchronously drives the second sliding plate 7 to move, the second sliding plate 7 scrapes sludge accumulated on the inclined side wall of the sludge hopper 17 to the middle of the sludge hopper 17 in the moving process, and the sludge on the inclined side wall of the sludge hopper 17 flows to the bottom of the sludge hopper 17 in the scraping process of the second sliding plate 7; when the mud scraper 2 scrapes the mud at the bottom of the sedimentation tank into the mud bucket 17 and the L-shaped second sliding plate 7 moves under the action of the first sliding plate 4, the mud can flow along the inclined bottom of the mud bucket 17, is immediately scraped to the vicinity of the mud suction pipe 3 by the second sliding plate 7 and is finally sucked out by the mud suction pipe 3; after the first sliding plate 4 and the second sliding plate 7 scrape sludge at the bottom of the sludge hopper 17 to the sludge suction pipe 3 for suction, the motor 9 drives the first sliding plate 4 and the second sliding plate 7 to move to the first groove 16 formed in the two parallel side walls of the sludge hopper 17 along the threaded rod 5 and the sliding rod 6, when sludge accumulated on the bottom surface of the sludge hopper 17 needs to be scraped, the motor 9 is started again, the motor 9 drives the threaded rod 6 to rotate, the threaded rod 6 enables the first sliding plate 4 and the second sliding plate 7 to scrape the sludge to the vicinity of the sludge suction pipe 3, and the sludge suction pipe 3 sucks the sludge; the elastic annular sleeve 42 is made of rubber; when the first sliding plate 4 moves back and forth along the threaded rod 5, the annular sleeve 42 can scrape sludge accumulated on the threaded rod 5, so that the sludge falls to the bottom surface of the sludge hopper 17 and is finally scraped to the vicinity of the sludge suction pipe 3 by the first sliding plate 4 to be sucked out of the sedimentation tank;
then, after sludge at the bottom of the sedimentation tank is scraped for a period of time, a scraping plate 21 arranged on the mud scraper 2 is moved to the position of a scraping plate 8, a motor 9 is started to drive a first sliding plate 4 to move, meanwhile, the first sliding plate 4 drives the scraping plate 8 to move through a second sliding plate 7, one side end face of the scraping plate 8 is in contact with one side end face of the scraping plate 21 close to the scraped mud, the sludge attached to the end face of the scraping plate 21 is scraped, the scraped sludge flows to the bottom face along the inclined side face of a sludge hopper 17, and finally the sludge is scraped to the vicinity of a sludge suction pipe 3 by the first sliding plate 4 and is sucked out by the sludge suction pipe 3; the elastic side of the scraping plate 8 is made of rubber materials, the rigid side of the scraping plate 8 is made of alloy steel materials, when sludge on the scraping plate 21 is cleaned by the scraping plate 8, the mud scraper 2 is started to drive the scraping plate 21 to extrude the scraping plate 8 on the flexible side to move upwards, and when the scraping plate 21 is not in contact with the scraping plate 8 any more, the scraping plate 8 which is extruded by the scraping plate 21 to deform returns to the original shape; when the first sliding plate 4 moves into the first groove 16, the first sliding plate 4 can extrude sludge stored in the first groove 16, and the sludge is extruded by the first sliding plate 4 and flows into a sludge hopper 17 along a chamfer formed in the first groove 16; the first sliding plate 4 with the elastic side is made of soft rubber; when the first sliding plate 4 enters the first groove 16, in order to extrude sludge accumulated in the middle of the bottom of the first groove 16, the arc surface of the first sliding plate 4 needs to be extruded on the end surface of the bottom of the first groove 16, when the sludge in the middle of the bottom of the first groove 16 is extruded by the first sliding plate 4, the sludge moves towards two sides of the bottom of the first groove 16, finally, along with the gradual increase of the contact surface between the first sliding plate 4 and the first groove 16, the space accumulated in the bottom of the first groove 16 is gradually reduced, and finally, the sludge in the first groove 16 flows into the sludge hopper 17 from the chamfer.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
