Three-phase rotational flow filter

Abstract

The present invention provides a three-phase swirl filter, relates to a filtering and separating machinery, the filter includes an arc tangential feeding inlet, a multi-functional axes, an external cylinder and a rigid filtering medium internal cylinder, the multifunctional axes is welded with a flange, the rigid filtering medium internal cylinder is mounted on the multifunctional axes, and formed by flange and tapered nut; the external cylinder composed of a straight cylinder and a cone which taper angle is 20-60 degree is mounted on the multifunction axes, and fixed by fastening nut and reject valve. A ring swirl filtering separating chamber is formed between the external cylinder and the rigid filtering medium internal cylinder, a light solid and a heavy solid are separated to the external surface of the rigid medium and the external cylinder wall respectively, reducing the solid sediment yield of the rigid filtering medium external surface. The swirl filter is fit for swirl filtering separating of the solid-liquid-solid three-phase suspension.

Description

technical field [0001] The invention relates to a mechanical device for filtration and separation, in particular to a mechanical device for cyclone clarification, filtration and separation of solid-liquid-solid three-phase (liquid phase, solid phase lighter and heavier than liquid phase) suspension. Background technique [0002] At present, the filtration methods similar to the cyclone filtration include centrifugal filtration, centrifugal sedimentation, cyclone separation and the like. [0003] The corresponding representative centrifugal filtration and sedimentation machines used in the industry include: three-legged centrifugal filtration, sedimentation machines, spiral discharge centrifugal filtration, sedimentation machines and other centrifugal separation machinery. The basic principle is to rely on external centrifugal force and the separation of two-phase materials. The density difference realizes centrifugal filtration or sedimentation separation. Some centrifuges ...

AI Technical Summary

Problems solved by technology

Its principle is to rely on the tangential feeding of its own structure to form a rotating centrifugal force field to separate large particles from the bottom flow pipe, and the liquid and other impurities less than or equal to the liquid density will overflow from the overflow pipe. Although continuous separation can be achieved, the main thing is the overflow. Contains other impurities less than or equal to the liquid phase density, which cannot achieve the purpose of clarification
