Variable-angle swirler

Abstract

The invention discloses a variable-angle swirler. The variable-angle swirler comprises a shell, a gas inlet channel and a gas outlet channel. The gas inlet channel communicates with the bottom of theshell. The gas outlet channel communicates with the upper end of the shell. The side wall surface of the shell communicates with a pressure measuring opening. Hole-shaped accelerating plates are sequentially arranged in the shell from top to bottom. The variable-angle swirler further comprises a conical support, a conical variable-angle frame and a circle of sliding groove. The conical support isembedded into the inner wall of the shell through a sliding structure. The conical variable-angle frame is embedded in the conical support. The sliding groove is formed in the inner wall of the shell.The other end is fixed to a part composed of a pair of sliding bodies on the outer wall of the conical support. A rotating shaft is arranged at the bottom of the conical support. A speed reducing motor is fixedly arranged at the lower end of the rotating shaft. According to the technical scheme of the variable-angle swirler, liquid is conveyed upwards through the rotational flow generated by thespeed reducing motor after being accelerated.

Description

technical field [0001] The invention relates to the technical field of swirlers, in particular to a variable-angle swirler. Background technique [0002] The suspension enters the hydrocyclone from the feed pipe at a high speed along the tangential direction. Due to the limitation of the outer cylinder wall, the liquid is forced to rotate from top to bottom. This movement is usually called external swirling flow or Down swirl movement. The solid particles in the external swirling flow are subjected to centrifugal force. If the density is greater than that of the surrounding liquid (this is most cases), the centrifugal force it receives will be greater. Once this force is greater than the liquid resistance caused by motion, the solid particles will It will overcome this resistance and move towards the wall of the device, and be separated from the suspension. The particles that reach the wall of the device are pushed by the continuous liquid, move down the wall of the device,...

Problems solved by technology

At the same time, because the bottom flow port of the hydrocyclone separator is greatly reduced, the liquid cannot be discharged from the bottom flow port quickly, and the overflow port in the center of the top cover of the cyclone chamber, because it is in a low-pressure area, a part of the liquid moves to it, thus forming an upward rotary motion , and discharged from the overflow port

In the prior art, the mechanical swirl is used, and the swirl effect is not good in some occasions
