Description

Multi-product swirler

Technical Field

The utility model relates to a whirl equipment especially relates to a many products swirler.

Background

Cyclones are common sorting, separating and classifying equipment, especially used in the field of mineral processing as the main industrial sorting equipment, and their working principle is to separate various kinds of multiphase mixtures with certain density difference under the action of centrifugal force. For example, one of the devices of the cyclone is called a two-product dense medium cyclone (cone), which tangentially enters a mixed solution of a medium and a material into the cyclone under a certain pressure, a high-speed rotating flow field is generated in a cylindrical cavity of the cyclone, the material with high density in the mixture moves downwards along the axial direction under the action of the cyclone field and simultaneously moves towards the inner wall of the cylindrical cavity, finally enters a conical section cavity and then moves downwards along the inner wall of the conical section cavity, and is finally discharged from a bottom flow port, and a downward outer cyclone is formed; the material particles with low density move towards the direction of the central axis, form an inner vortex moving upwards in the center of the axis, and then are discharged from the overflow port, so that two materials with different densities are separated, and the aim of separating the mixture according to different densities is fulfilled. And it has the advantages of simple structure, no moving parts, high separation efficiency and the like, so that it has wide application, especially in the field of mineral separation.

The traditional three-product heavy medium cyclone is actually formed by connecting two heavy medium cyclones in series, so that the floor area of a single traditional three-product heavy medium cyclone is larger than that of a single two-product heavy medium cyclone.

The first section of the traditional three-product dense medium cyclone is a main selection section, and low-density materials and re-selection materials are sorted out; the second section is a re-selection section, and two products of medium-density materials and high-density materials are separated. However, the two-stage reselected feed of the three-product dense medium cyclone has similar density and small density difference, so the two-stage reselected feed is generally a mixture which is difficult to sort, and a longer sorting path is needed to prolong the sorting time to improve the sorting effect. However, the two-stage of the conventional three-product dense medium cyclone is a two-product dense medium cyclone, and if the separation path needs to be extended, the length of the cylindrical or conical cylinder can be increased, and the occupied area of the cyclone is also increased remarkably.

At most, the prior cyclone can only sort out three products, and the three-product cyclone is not a true three-product cyclone and is just a series connection of two-product cyclones.
