[0024] A coal-water sedimentation tank coal slime cleaning device comprises a sedimentation tank 1, wherein an inclined slope 19 is installed on the inner bottom wall of the sedimentation tank 1, a sliding groove is provided on one side of the sedimentation tank 1, a diverter plate 2 is slidably installed in the sliding groove, a plurality of diverter holes are provided on one side of the diverter plate 2, a flushing nozzle 3 is installed in each of the plurality of diverter holes, a scraper 10 is installed on the lower side of the diverter plate 2, the scraper 10 corresponds to the inclined slope 19, a water inlet is provided on the upper side of the diverter plate 2, an electric valve 4 is installed in the water inlet, a driving block 7 is installed on one side of the diverter plate 2, a guide port is provided on one side of the sedimentation tank 1, a movable door 11 is rotatably installed in the guide port.

[0025] Based on the above structure, the sliding groove is parallel to the inclined surface of the inclined plate, the diverter plate 2 is hollow inside and has a plurality of diverter holes and a high-pressure nozzle on one side. Before use, the external water source needs to be installed on the electric valve 4, and the drive block 7 on the other side of the diverter plate 2 drives the diverter plate 2 to move along the surface of the inclined slope 19, and the electric valve 4 is opened to inject clean water into the diverter plate 2, and the inclined slope 19 is flushed through the nozzle, and then the scraper 10 arranged at the bottom of the diverter plate 2 is used to scrape the stubborn coal slime on the cut inclined plate to the bottom of the sedimentation tank 1, and the movable door 11 is opened to discharge the coal slime and clean it.

[0026] like Figure 2 and 3 As shown, a movable groove is provided on the inner wall of the sedimentation tank 1, and a movable block 5 is slidably installed in the movable groove. A limit bar 6 is slidably installed on one side of the movable block 5. A slide rail is provided on the side of the sedimentation tank 1 close to the movable block 5. The limit bar 6 is slidably installed on the slide rail through a slider. The driving block 7 is slidably installed on the inner wall of the limit bar 6. When the limit bar 6 is driven by the movable block 5, due to the limiting effect of the slide rail, the limit bar 6 first performs a planar motion, and then performs a vertical downward motion during the planar motion, thereby driving the driving block 7 to perform an inclined motion along the surface of the inclined slope 19.

[0027] like Figure 2 and 3As shown, a first driving hole is opened on one side of the sedimentation tank 1, and a first-level threaded rod 8 is rotatably installed in the first driving hole, and a moving block 5 is screwed and installed on the surface of the first-level threaded rod 8. A first-level motor 9 is installed on one side of the sedimentation tank 1, and the output end of the first-level motor 9 is coaxially installed with one end of the first-level threaded rod 8.
