Description

The invention relates to the textile industry, in particular to the field of dusty air cleaning by means of a cyclone.

Cyclones are known with an inlet pipe in one housing parallel to the cyclone axis and tangential outlet.

In such cyclones, air is cleaned only from fine dust.

To clean the dusty air from fluff, the inlet of the proposed cyclone is mounted along its axis, and hollow truncated cones placed one above the other are mounted inside the body. The upper cone with a large base is fixed on the wall of the housing, and the lower with a smaller base - 1M inlet.

The drawing shows the scheme of the proposed cyclone.

It contains a body /, inlet 2 and outlet 3 nozzles, hollow truncated cones 4 and 5, as well as a dust outlet nozzle 6 communicating with a hopper 7 located under the cyclone.

The air is purged with a cyclone as follows. The dusty air at high speed enters the cyclone through the axial nozzle 2, which has a conical tapering opening at the end, at the exit of which the dust is centrifugally shed to the walls of the housing /.

The air entering the cyclone creates an increased pressure in its conical part. Due to this, air with dust, pressed to the walls, rises and encounters an annular labyrinth formed by a pair of hollow truncated cones 4 and 5. As it passes through this labyrinth, the dust, lost speed, is separated from the air and output through the dust outlet pipe 6 to the bunker 7. The air is

continuing upward movement, out of the cyclone through the tangential nozzle 3.

The fluff in the dusty air, passing through the axial nozzle 2, continues to move along the axis of the cyclone and also enters the hopper 7. The movement of the fluff along the axis at high speed is ensured by the fact that air with dust pressed to the walls of the body as if compressed air entering the cyclone axis, thereby increasing the speed

stream, in which there is a hole, without allowing the latter to remain in the cyclone.

Thus, the fluff in the dusty air is separated from it and collected in the bunker 7, from where it is removed

by.

The subject matter of the invention

This is due to the fact that, in order to clean the dusty air from fuzz, the inlet pipe is mounted along the axis of the cyclone, and the concentric ones located inside the case are located one above

the others have hollow truncated cones, the upper of which is fixed by a large base on the wall of the housing, and the lower one by a smaller base on the inlet nozzle.
