Cyclone desander device

Abstract

The invention provides a swirl desander device, which comprises a swirl upper cylinder and a swirl lower cylinder, the swirl upper cylinder and the swirl lower cylinder are connected by bolts, and the upper part of the swirl upper cylinder is provided with a liquid outlet pipe ,The eccentric position of the upper cylinder is equipped with a liquid inlet pipe, the outer circumference of the lower cylinder is equipped with a protective cover, the two sides of the lower cylinder are respectively equipped with flushing devices, and the bottom of the lower cylinder is provided with a sand discharge port , The flushing device includes a switch valve, a spray pipe and a base, the switch valve and the base are connected by bolts and fixed on the swirling lower cylinder, and the spray pipe is arranged on the base. The problem to be solved by the present invention is to provide a cyclone desander with simple structure, small volume, safety and reliability, good sand discharge effect, and more thorough treatment of residual sand particles on the inner wall in all directions.

Description

technical field [0001] The invention relates to a solid-liquid separation device, in particular to a cyclone desander device. Background technique [0002] Cyclone desander is a kind of solid-liquid separation equipment based on centrifugal sedimentation and density difference mechanics. The impact of the structure of the desander produces strong rotation. Due to the different densities of water and sand, under the joint action of buoyancy, centripetal force and fluid drag, the clean water with low density rises and flows out from the top overflow port, while the dense sand It settles to the bottom along the inner wall of the desander and is discharged from the sewage outlet. In the field of water treatment, the effects of sand removal, turbidity reduction, and solid-liquid separation are remarkable. It is widely used in decontamination of heat exchange stations, desanding of river water and well water, lime pulping and other fields. During the sand removal process, the d...

AI Technical Summary

Problems solved by technology

During the sand removal process, the desander will cause great friction and damage to the equipment, resulting in a low service life of the equipment. At the same time, the existing equipment generally discharges sand directly, and the effect of sand removal is not thorough enough, causing impurities to remain in the cylinder. In the body, it will cause congestion for a long time, and the sand removal effect will be reduced

[0003] At present, some methods to deal with residual sand particles in the cylinder are to install a flushing water pipe, but the flushing water pipe is only processed in one direction, and cannot be cleaned in all directions, so that residual impurities will still remain in the cylinder
