A variable angle cyclone

Abstract

The invention discloses a variable angle swirler, which comprises a casing, an air inlet channel and an air outlet channel, the inlet channel communicates with the bottom of the housing, the air outlet channel communicates with the upper end of the housing, and the side of the housing The wall surface is connected with a pressure measuring port, and the inside of the housing is sequentially provided with a hole-shaped acceleration plate from top to bottom, which also includes: a tapered bracket, a tapered angle-changing frame, and the tapered bracket is embedded through a sliding structure On the inner wall of the housing, the conical angle-changing frame is embedded in the conical bracket, which also includes: a circle of chute opened on the inner wall of the housing, and the other end is fixed on the outer wall of the conical bracket. Yes, the bottom of the tapered support is provided with a rotating shaft, and the lower end of the rotating shaft is fixedly provided with a geared motor. In the technical solution, after the liquid is accelerated, the swirling flow is generated by the geared motor to transport the liquid upward.

Description

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

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
