SU510269A1 - Hydrocyclone for separating suspensions into fractions - Google Patents

Description

one

The invention relates to devices for separating suspensions into fractions under the action of centrifugal forces and can be used in the mining, chemical, food, pulp and paper and other industries.

A hydrocyclone is known for separating suspensions into fractions, including two oppositely directed conical chambers with sand pipes installed on smaller bases, connected by large bases to a cylindrical chamber equipped with inlet and drain pipes. In a known hydrocyclone, it is impossible to smoothly change the inlet section of the inlet.

The purpose of the invention is to increase the separation efficiency.

In the proposed hydrocyclone, the cylindrical chamber is provided with a hollow partition, the internal cavity of which is connected to the drain pipe and which is rotatably mounted relative to the cylindrical chamber. Due to this, it is possible to smoothly change the cross-sectional area of the inlet nozzle without disconnecting the hydrocyclone.

FIG. 1 shows a hydrocyclone, a general view; in fig. 2 is a section along A-A in FIG. one

with the open position of the inlet and drain pipes; in fig. 3 is a section along A-A in FIG. 1 when the inlet and outlet nozzles are closed.

A hydrocyclone consists of two oppositely directed conical chambers 1 with sand pipes 2 installed on smaller bases. The conical chambers are connected by large bases with a cylindrical chamber 3, equipped with an inlet 4 and a drain 5 nozzles.

In the cylindrical chamber 3, a partition wall 6 is provided, provided with two axial drainage pipes 7 communicating through the internal cavity B and opening a with a drain pipe 5. Rotation of the hollow partition 6 relative to the cylindrical chamber 3 is carried out using a lever 8 and is limited by the size of the through groove 9.

Hydrocyclone works as follows. The original suspension under pressure is fed into the inlet 4 of the hydrocyclone. In a hydrocyclone under the action of centrifugal

the suspension forces are divided into fractions. The heavy fraction moves along the walls of the conical chambers and is discharged through the sand pipes 2. The clarified fraction passes through the drain pipes 7 into the internal cavity B of the hollow partition 6 and then through

the hole a is withdrawn from the hydrocyclone through a common discharge nozzle 5.

If it is necessary to change the cross section of the inlet 4, the hollow partition 6 is rotated relative to the cylindrical chamber 3 by means of a lever 8, which is inserted into a through groove made in the body of the partition 6.

Providing a cylindrical hydrocyclone chamber with a hollow partition, the internal cavity of which is connected to the drain pipe and which is installed rotatably relative to the cylindrical camera, allows you to adjust the cross section of the inlet pipe, as well as the cross section of the drain pipe during operation of the hydrocyclone, which contributes to the separation efficiency.
