Retractable hydrocyclone

Abstract

The invention discloses a retractable hydrocyclone and belongs to multi-phase flow separation equipment. The retractable hydrocyclone comprises a feeding hole, an overflow pipe, a swirling chamber, a separation zone and an underflow pipe, wherein the separation zone is a main separation working part and is characterized by being formed by nested connection of a plurality of column segments with different internal diameters. The length of the separation zone of the hydrocyclone has certain influence on the separation precision. The device can adjust the length of the separation zone of the hydrocyclone according to the separation precision of materials, namely when the concentration requirement of a to-be-separated substance changes, the length of the column segments of the separation zone of the hydrocyclone can be extended or shrunk directly according to requirements to achieve use requirements, without re-designing a new hydrocyclone. The hydrocyclone is increased in handling capacity, improved in separation efficiency, increased in underflow concentration, convenient to adjust and low in cost, and is applicable to separation operations of industries including petroleum, chemical engineering, coal dressing, food, sewage treatment and the like, especially applicable to occasions with requirements for obtaining multi-phase flow substances with different concentrations.

Description

technical field [0001] The invention relates to a shrinkable hydrocyclone, in particular to a multiphase flow separation device capable of adjusting the length of a separation zone, which belongs to fluid machinery. Background technique [0002] Hydrocyclone is a classification equipment that uses centrifugal force to accelerate the sedimentation of ore particles. Because of its simple structure, low cost, small size and large processing capacity, it is widely used in solid-liquid, liquid-liquid, liquid-gas separation. At present, the separation zones of various types of hydrocyclones used in enterprises are fixed in length. When the separation accuracy of the substances we need changes, we must re-purchase the hydrocyclones with corresponding structural parameters, so that Not only caused the shelving of the original cyclone, but also reduced the production efficiency. Therefore, there is an urgent need to invent a cyclone with an adjustable separation zone, which can quic...

Problems solved by technology

[0003] The purpose of the present invention is to provide a shrinkable hydrocyclone to solve the drawbacks of the existing hydrocyclone separation zone length fixed, the separation zone length of the hydrocyclone can not be changed with the change of use requirements, When the separation accuracy changes, the cyclone cannot achieve the required separation effect and cannot play a production role.
