Design method of high-efficiency hydrocyclone and high-efficiency hydrocyclone

Abstract

The invention relates to mine separation equipment, and provides a design method of a high-efficiency hydrocyclone, the high-efficiency hydrocyclone comprises a cyclone chamber, a cone structure, an overflow pipe and a sand setting port, the cyclone chamber comprises a cyclone chamber upper cover and a cyclone chamber cylinder, and the interior of the cyclone chamber cylinder is provided with a spiral downward rotation structure and a cyclone chamber cylinder base circle which are arranged up and down; a feeding port is formed in the spiral downward rotation structure, the feeding port, the spiral downward rotation structure and a base circle of the rotational flow chamber barrel are sequentially connected to form a feeding channel, the feeding port is of a shrinkage section structure, the overflow pipe is installed on the top of the rotational flow chamber upper cover and communicated with an inner cavity of the rotational flow chamber, and the upper end of the rotational flow chamber barrel is connected with the rotational flow chamber upper cover. The lower end of the cyclone chamber cylinder is connected with the upper end of the cone structure, and the lower end of the cone structure is connected with the sand setting opening. Through optimization design of parameters of the spiral underspin structure molded line, the pressure loss of ore pulp feeding can be reduced, high treatment capacity is obtained with low ore feeding pressure, and the grading efficiency is improved.

Description

technical field [0001] The invention relates to mine sorting equipment, in particular, to a design method of a high-efficiency hydrocyclone and a high-efficiency hydrocyclone. Background technique [0002] Hydrocyclones are widely used in petrochemical, environmental protection, food, medicine and other industries due to their simple structure, large production capacity, high classification efficiency and low investment. Especially in the beneficiation industry, it is used to remove the heavier coarse-grained ore and other substances in the pulp or for operations such as mud dewatering and concentration. [0003] At present, the hydrocyclone used for mine beneficiation and classification mainly adopts a double-shell structure, including a metal shell and an inner lining. The inner lining is generally made of wear-resistant materials such as rubber, polyurethane or ceramics, and high wear-resistant materials are used to absorb the kinetic energy of coarse particles and impac...

AI Technical Summary

Problems solved by technology

In the connection structure of the feed port and the cylinder of the cyclone chamber, tangent, involute, circular and helical forms are usually used. The first three structures are easy to process, but consume a lot of energy and have low classification efficiency.

At present, the mainstream cyclone design generally adopts the helical structure, but there are certain differences, and the classification efficiency is also different.
