Description

Multistage screening swirler

Technical Field

The utility model relates to a gather sample technical field, more specifically be a multistage screening swirler.

Background

A fluid cyclone is a common separation and fractionation device, and the centrifugal sedimentation principle is commonly used. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone under a certain pressure, strong three-dimensional elliptical strong-rotation shearing turbulent motion is generated. Because the particle size difference exists between the coarse particles and the fine particles, the coarse particles and the fine particles are subjected to different sizes of centrifugal force, centripetal buoyancy, fluid drag force and the like, and under the action of centrifugal sedimentation, most of the coarse particles are discharged through a bottom flow port of the cyclone, and most of the fine particles are discharged through an overflow pipe, so that the purposes of separation and classification are achieved.

The basic principle of the cyclone is to separate two-phase or multi-phase mixtures with certain density difference, such as liquid-liquid, liquid-solid, liquid-gas, etc., under the action of centrifugal force. The mixed liquid tangentially enters into the cyclone under a certain pressure to generate a high-speed rotating flow field in the cylindrical cavity. The components with high density in the mixture simultaneously move downwards along the axial direction under the action of the cyclone field, move outwards along the radial direction, move downwards along the wall of the cone section when reaching the cone section, and are discharged from the bottom flow port, so that an outer vortex flow field is formed; the component with low density moves towards the direction of the central axis, forms an inner vortex moving upwards in the center of the axis and then is discharged from the overflow port, thus achieving the aim of separating two phases.

The raw materials inevitably contain a large amount of impurities, such as broken rubber, scales, wood chips, weeds and the like, and the sand settling nozzle of the cyclone is very small, so that the cyclone is very easy to block and difficult to clean, and brings great workload for maintainers.
