Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a cyclone for screening molybdenum concentrate. Background Art

[0002] Fluid cyclone is a common separation and classification equipment, which usually uses the principle of centrifugal sedimentation. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the difference in particle size between coarse particles and fine particles, they are subject to different centrifugal forces, centripetal buoyancy, fluid drag, etc. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the bottom flow port of the cyclone, while most of the fine particles are discharged from the overflow pipe, thereby achieving the purpose of separation and classification. Cyclones are needed for screening molybdenum concentrate.

[0003] Chinese patent publication number CN219850180U discloses a hydrocyclone that can reduce turbulence and vertical cross-mixing, improve the cleaning effect, reduce the resuspension of larger particles, and wash out smaller particles and lower-density solids and discharge them with overflow, while larger particles are concentrated to a higher concentration and discharged with underflow.

[0004] However, compared with the prior art and comparative documents, during use of the existing cyclone, coarse particles are discharged through the discharge port at the bottom of the cyclone. During the discharge process, the coarse particles fall through the material at a fast speed, which can easily cause the discharge port to be blocked, thereby causing the device to fail to work.
