[0037] Working principle of the utility model:

[0038] The low concentration fine particle tailings are flowed into the cyclone 92 through the inlet pipe 91, and the flocculating agent is added through the flocculating agent adding pipe 93 at the same time, and then the tailings are settled and compacted in the barrel of the cyclone 92, and the clean water is flowed into the overflow pipe 94 for use as backwater; the high concentration tailings pulp is entered into the conical mouth part 13 at the bottom of the conical silo 12 from the conical silo 12 at the bottom of the cylindrical silo 11, and is discharged through the discharge pipe 14 at the outer periphery of the conical mouth part 13.

[0039] The connecting sleeve 61 of the anti-blocking mechanism 6 is driven to rotate synchronously under the fixation of the connecting rod 63, and the rotation of the spiral rake 62 stirs the high concentration tailings pulp entering the conical mouth part 13 in the same direction, so that the high concentration tailings pulp is in a flowing state and is not easy to condense in the conical mouth part 13, and the flowing high concentration tailings pulp is also easy to be discharged from the discharge pipe 14 at the outer periphery of the conical mouth part 13, so that the phenomenon of blockage of the discharge pipe 14 is not easy to occur.
