For better cleaning the sieving cylinder 20, a leaching mechanism 40 is installed above the sludge pond 10, the leaching mechanism 40 comprises a support frame 41 fixed with the sludge pond 10 and a spray pipe 42 fixed at the upper end of the support frame 41, and water can be sprayed to the surface of the sieving cylinder 20 through the spray pipe 42 in the rotating process of the sieving cylinder 20, so that solids clamped in the sieve pores of the sieving cylinder 20 can be washed down, and meanwhile, the leaching mechanism 40 can ensure that good sliding contact between the separation push plate 33 and the separation pipe 31 can be kept.

Further, the inlet end of the separating tube 31 near the sieving cylinder 20 is a closed structure, and a flushing tube 34 is installed at one end of the separating tube 31 located in the closed structure, and when solids on the bottom side of the separating tube 31 accumulate, flushing can be performed through the flushing tube 34.

In some embodiments, the shower pipe 42 is connected to the sludge basin 10 by a suction pump 43.

The working principle of the solid-liquid separation device for mine tail mud is as follows:

When the mine tailing sludge is added through the inlet end of the sieving cylinder 20, the mud water part rapidly flows into the sludge pond 10 through the sieve holes of the sieving cylinder 20 under the action of gravity and centrifugal force, so that preliminary solid-liquid separation is realized. While solids are trapped on the inside wall of the screen drum 20 and the separator push plate 33 becomes active as the screen drum 20 rotates. The separation pushing plate 33 pushes the solid matters along the inner wall of the sieving cylinder 20 toward the separation tube 31 by the force generated by the rotation. In this process, the separation pushing plate 33 not only effectively prevents the accumulation of solids at the bottom of the screening drum 20, but also ensures that the solids can move to the opening 32 on the side surface above the separation tube 31, and when the solids reach the opening 32, the solids automatically fall into the separation tube 31 under the action of gravity, thereby realizing the automatic cleaning of the solids. In addition, due to the inclined arrangement and continuous rotation of the sieving cartridge 20, part of the solids are discharged directly through the lower end of the sieving cartridge 20 under the action of gravity, further improving the separation efficiency. In order to keep the sieving cartridge 20 clean and prevent clogging of the sieve openings, the device is also provided with a rinsing mechanism 40. The rinsing mechanism 40 sprays water to the surface of the sieving cylinder 20 through the spray pipe 42 to wash away fine solids stuck in the sieve holes, and enters the inside of the separation pipe 31 through the opening 32 to clean the separation pipe 31. Meanwhile, the leaching mechanism 40 can also ensure that the separation pushing plate 33 and the separation pipe 31 keep good sliding contact, so that the working efficiency of the separation mechanism is improved.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
