Abstract

The invention relates to a wear-resistant and washout-resistant cyclone and a manufacturing method of a lining of the cyclone, and relates to a cyclone in a separating and classifying apparatus. A rubber lining is arranged in the cyclone; the rubber lining is formed by binding two different rubber materials, and special wear-resistant rubber is applied at the surface layer; the framework of the wear-resistant rubber is composed of aramid glass fibers and polyamide fibers, and then the special wear-resistant rubber is taken as a base material and mixed with the framework, and in the mixing process, materials having high wear resistance such as silicon carbide micro-powder or zirconium carbide micro-powder, alumina micro-powder, silica micro-powder and monatomic silicon micro-powder are packed, so that the strength, wear resistance, washout resistance and puncture resistance of the rubber lining are greatly improved; as a result, the rubber lining is enabled to have certain strength, abrasive resistance, washout resistance and puncture resistance, and also have certain rebound resilience and flexibility, and the service life of the cyclone is greatly prolonged.

Description

technical field [0001] The invention relates to a cyclone in separation and classification equipment, in particular to a method for manufacturing the wear-resistant and scour-resistant cyclone and its lining. Background technique [0002] As a common separation and classification equipment, the cyclone works on the principle of centrifugal sedimentation. When the two-phase (or three-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 rotating shear turbulent movement is generated. Due to the particle size difference (or density difference) between coarse particles (or heavy phase) and fine particles (or light phase), the centrifugal force, centripetal buoyancy force, and fluid drag force they receive are different. Part of the coarse particles (or heavy phase) is discharged through the bottom outlet of the cyclone, while most of the fine particles (or light ...
