A wear-resistant hydrocyclone structure

Abstract

The invention relates to the technical field of separation equipment, and discloses a wear-resistant hydraulic cyclone structure. The wear-resistant hydraulic cyclone structure comprises a cylinder body and a conical section; a discharging pipe is arranged at the lower end of the conical section, an overflow pipe is arranged in the center of the top surface of the cylinder body, a feeding pipe isarranged on the side surface of the cylinder body, an annular distributor is arranged on the outer side of the cylinder body, the feeding pipe is in communication with the side surface of the annulardistributor, a plurality of feeding branch pipes are uniformly arranged on the side surface of the cylinder body, the feeding branch pipes are distributed along the tangential direction of the cylinder body, and the outer ends of the feeding branch pipes are in communication with the annular distributor; a taper sleeve is arranged on the inner wall of the conical section, the upper end of the taper sleeve extends outwards to form a guide conical surface, the top angle of the guide conical surface is larger than the top angle of the taper sleeve, the upper end of the guide conical surface is fixedly connected to the upper end of the conical section, and a speed reducing cavity is formed between the conical sleeve and the inner wall of the conical section; and a plurality of flow guiding holes are uniformly distributed in the inner wall of the taper sleeve. The wear-resistant hydraulic cyclone structure has the beneficial effects of being resistant to wear and long in service life.

Description

technical field [0001] The invention relates to the technical field of separation equipment, in particular to a wear-resistant hydrocyclone structure. Background technique [0002] Hydrocyclone is a kind of separation equipment. Its principle is to separate solid-liquid, liquid-gas, solid-solid, liquid-liquid, liquid-gas-solid and other mixtures with a certain density difference under the action of centrifugal force. It is widely used in chemical industry, petroleum , mineral processing, environmental protection, pharmaceuticals, food, light industry, wastewater treatment, papermaking and many other fields. The hydrocyclone is generally composed of a feed inlet, a cylinder, a conical section, an overflow pipe and a discharge outlet of the cone section. The mixture and water enter the cylinder from the feed inlet along the tangential direction to form a swirling flow, and then flow in the cylinder. , and a centrifugal force field is constructed at the conical section, and tw...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the inner wall of the hydrocyclone in the prior art is short-lived due to the friction and impact of the solid particles in the external swirling flow for a long time, the present invention provides a wear-resistant hydrocyclone structure, which can be extremely Greatly weaken the impact and friction of solid particles in the external swirling flow on the inner wall of the cone section, greatly slow down the wear of the inner wall of the cone section, and improve the overall service life
