Cyclone with rubber liner, and production method of rubber liner

Abstract

The invention relates to a cyclone with a rubber liner, and a production method of the rubber liner, and relates to a cyclone in separating and grading equipment. The rubber liner is arranged in the cyclone. The production method of the rubber line comprises the following steps: forming a skeleton by using aramid glass fibers and nylon fibers, and then mixing special corrosion-resistant rubber as a base material with the aramid glass fibers and nylon fibers; filling high-wear-resistant materials such as zirconium carbide micro powder, alumina micro powder, silicon oxide micro powder and elemental silicon micro powder in an assistant manner in the mixing process, thus obtaining a rubber material with high strength, good wear resistance, good erosion resistance and good puncture resistance, wherein a layer of wear resistant ceramic wafers is adhered to the surface of the rubber material so as to further enhance the wear resistance, the erosion resistance and the puncture resistance, and then the rubber material is taken as a liner material. The rubber liner has very high wear resistance, erosion resistance and puncture resistance, and also has certain resilience and flexibility, so that 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 hydrocyclone with a rubber lining and a manufacturing method for the 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 phase) are ...

Problems solved by technology

[0005] In order to solve the problem of low service life of the existing cyclone lining, the present invention provides a hydrocyclone with a rubber lining and a method for making the lining. The lining uses a unique rubber material, sacrificing the rubber The partial elasticity of the material improves its wear resistance, erosion resistance and puncture resistance, and a layer of wear-resistant ceramic sheet is attached to the surface, thus greatly improving the service life of the cyclone
