Through the coordinated use of the fixing plate 20, the sliding block and the sliding groove 21, guidance can be provided for the electric slider 18 when it slides up and down on the guide rail 17.

[0026] As a technical optimization solution of the utility model, limit blocks 19 are installed at both ends of the guide rail 17. The limit blocks 19 are installed on the outer wall of the rotating shaft 11. The limit blocks 19 can provide a limit for the electric slider 18 to avoid the electric slider 18 and the guide rail 17 from detaching.

[0027] As a technical optimization solution of the utility model, a first motor 7 is installed on the top of the tank body 6, and the output shaft of the first motor 7 is inserted into the tank body 6 and connected to one of the rotating shafts 11.

[0031] When the utility model is used, when the coal slurry needs to be filtered, firstly, the coal slurry to be filtered is poured into the tank body 6 through the feed port 10 at the top of the tank body 6 .

[0032] After the coal slurry to be filtered is poured into the tank body 6, the first motor 7 and the second motor 9 are started at the same time, and the output shafts of the first motor 7 and the second motor 9 rotate in opposite directions.

[0033] At this time, the rotation of the rotating shaft 11 can drive the stirring rod 12 to rotate, and the rotation of the stirring rod 12 can drive the mounting sleeve 13 and the crushing protrusion 14 on the outer wall of the mounting sleeve 13 to rotate. The coal slurry in the tank body 6 is stirred by the rotation of the stirring rod 12, the mounting sleeve 13 and the crushing protrusion 14. The coal slurry can be pre-stirred first, thereby ensuring that the coal slurry is in a uniform state when entering the disc vacuum filter 4, thereby reducing the stirring work of the coal slurry by the disc vacuum filter 4, so that the disc vacuum filter 4 can fully stir the coal slurry when filtering the coal slurry, thereby improving the filtration efficiency of the disc vacuum filter 4 on the coal slurry.

[0034] While the coal ore slurry is stirred by the stirring rod 12, the mounting sleeve 13 and the crushing protrusion 14 in the tank body 6, the crushing protrusion 14 in the rotation process will collide with the large particles of coal ore in the coal ore slurry, and the large particles of coal ore in the coal ore slurry are crushed by the collision of the crushing protrusion 14 on the outer wall of the mounting sleeve 13 with the large particles of coal ore in the coal ore slurry, and the rotation directions of the two rotating shafts 11 are opposite, and the large particles of coal ore in the coal ore slurry can be crushed by the mounting sleeve 13 and the crushing protrusion 14 located above and the mounting sleeve 13 and the crushing protrusion 14 located below rotating in the opposite direction, so that the large particles of coal ore in the coal ore slurry can be crushed, thereby preventing the large particles of coal ore in the coal ore slurry from entering the disc vacuum filter 4 and clogging the filter screen in the disc vacuum filter 4.

[0035] After the coal slurry is stirred and the large coal ore particles in the coal slurry are crushed, the coal slurry can enter the disc vacuum filter 4 through the discharge port 16 for filtering.

[0036] After the coal slurry is stirred and crushed, the electric slider 18 can be started. The electric slider 18 slides on the guide rail 17 to adjust the height of the stirring rod 12, the mounting sleeve 13 and the crushing protrusion 14 in the tank body 6.

At this time, starting the first motor 7 and the second motor 9 can rotate the two rotating shafts 11, thereby rotating the stirring rod 12, the mounting sleeve 13 and the crushing protrusion 14, and the scraper 15 Rotation can scrape off the residual coal slurry attached to the inner wall of the tank body 6, and the crushing protrusion 14 connected to the inner bottom wall of the tank body 6 can scrape the coal slurry attached to the inner bottom wall of the tank body 6 to loosen it from the inner bottom wall of the tank body 6. The crushing protrusion 14 connected to the inner top wall of the tank body 6 can scrape the coal slurry attached to the inner top wall of the tank body 6 to loosen it from the inner top wall of the tank body 6, and then the coal slurry attached to the inner wall of the tank body 6, the inner top wall of the tank body 6, and the inner bottom wall of the tank body 6 can be scraped loose. At this time, the inner wall of the tank body 6 can be cleaned by flushing it with clean water, and the sewage can be discharged by discharging the flushing water through the discharge port 16, which is convenient for the later cleaning of the inner wall of the tank body 6.
