when the invention is used, a worker adds water 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 is stabilized to flow into the sedimentation tank; starting a mud scraper 2, wherein the mud scraper 2 drives a scraping plate 21 to move, when the scraping plate 21 moves to the surface of a water body, floating scum on the surface of the water body is pushed into a scum groove 15, and when the scraping plate 21 moves to the bottom of a sedimentation tank, the scraping plate 21 scrapes mud stored in the bottom of the sedimentation tank to a mud bucket 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 rotation motion of the motor into the linear motion of the first sliding plate 4, so that the first sliding plate 4 moves towards the middle part of the sludge hopper 17, and the sliding rod 4 which is in sliding connection with the other side synchronously moves towards the middle part of the sludge hopper 17 when the threaded rod 5 rotates due to the fact that the rotation direction of the threads on the threaded rod 5 is oppositely arranged from the middle part to the two ends, and when the two first sliding plates 4 move close to each other, the sliding rod 6 can guide the first sliding plate 4, so that the first sliding plate 4 always keeps stably moving; finally, the two sliding plates 4 which are mutually close to each other push the sludge deposited on the bottom surface of the sludge hopper 17 to the position in the sludge hopper 17 which is close to the sludge suction pipe 3, and the sludge suction pipe 3 sucks the sludge near the pipe body to enter the next link of sludge treatment; when the first sliding plate 4 moves towards the middle part of the sludge hopper 17, the sludge at the bottom of the sludge hopper 17 can be scraped to a position near the sludge suction pipe 3 at the middle part of the sludge hopper 17, meanwhile, the two opposite moving first sliding plates 4 are contacted with each other, the semicircular grooves 41 are spliced together to form a whole circle, and the outer wall of the sludge suction pipe 3 is just wrapped;
then, when the first slide plate 4 moves towards the middle of the sludge hopper 17, the first slide plate 4 synchronously drives the second slide plate 7 to move, the second slide plate 7 scrapes the sludge stored 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 slide plate 7; when the sludge scraper 2 scrapes the sludge at the bottom of the sedimentation tank into the sludge hopper 17, the L-shaped second slide plate 7 moves under the action of the first slide plate 4, the sludge can flow along the inclined bottom of the sludge hopper 17, is scraped to the vicinity of the sludge suction pipe 3 by the second slide plate 7, and is finally sucked out by the sludge suction pipe 3; after the first slide plate 4 and the second slide plate 7 scrape the sludge at the bottom of the sludge hopper 17 to the sludge suction pipe 3 for suction, the motor 9 drives the first slide plate 4 and the second slide plate 7 to move along the threaded rod 5 and the slide rod 6 into a first groove 16 formed on two parallel side walls of the sludge hopper 17, when the sludge stored 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, and the threaded rod 6 enables the first slide plate 4 and the second slide plate 7 to scrape the sludge near 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 reciprocally along the threaded rod 5, the annular sleeve 42 can scrape the sludge stored on the threaded rod 5, so that the sludge falls to the bottom surface of the sludge hopper 17, and finally the sludge is scraped to the vicinity of the sludge suction pipe 3 by the first sliding plate 4 to suck out the sedimentation tank;
then, after scraping the sludge at the bottom of the sedimentation tank for a period of time, moving a scraping plate 21 arranged on the sludge scraper 2 to the position of a scraping plate 8, starting a motor 9 to drive a first sliding plate 4 to move, and simultaneously, driving the scraping plate 8 to move by a second sliding plate 7, wherein one side end surface of the scraping plate 8 is contacted with one side end surface of the scraping plate 21, which is close to the sludge scraping, and scraping the sludge attached to the end surface of the scraping plate 21, wherein the scraped sludge flows to the bottom along the inclined side surface of a sludge hopper 17, and is finally scraped to the vicinity of a sludge suction pipe 3 by the first sliding plate 4 and sucked out by the sludge suction pipe 3; the side of the scraping plate 8 with elasticity is made of rubber material, the side with rigidity is made of alloy steel material, when the sludge on the scraping plate 21 is cleaned up by the scraping plate 8, the scraping plate 8 on the flexible side is driven by the sludge scraper 2 to move upwards, and when the scraping plate 21 is not contacted with the scraping plate 8 any more, the scraping plate 8 which is deformed by the extrusion of the scraping plate 21 is restored to the original state; when the first slide plate 4 moves into the first groove 16, the first slide plate 4 can squeeze the sludge stored in the first groove 16, and the sludge flows into the sludge hopper 17 along the chamfer angle formed by the first groove 16 under the extrusion of the first slide plate 4; the first sliding plate 4 with one elastic side is made of soft rubber; when the first slide plate 4 enters the first groove 16, in order to extrude the sludge accumulated in the middle of the bottom of the first groove 16, the cambered surface of the first slide plate 4 is required to extrude 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 slide plate 4, the sludge moves to two sides of the bottom of the first groove 16, finally, along with the gradual increase of the contact surface of the first slide plate 4 and the first groove 16, the space accumulated by the sludge 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 has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
