Description

1 12

The invention relates to the technique of separation in the field of centrifugal forces of saline suspensions and can be used in mining, chemical, pulp and paper and other industries.

The purpose of the invention is to increase the separation efficiency by providing adjustment of the hydrocyclone in height and changing the shape of the inlet nozzle.

FIG. 1 shows a hydro clone, a general view; in fig. 2 - view A on. FIG. one; in fig. 3 - 5 - inlet at various positions of its adjustment in height and width, general view.

A hydrocyclone consists of a cylindro-conical body 1 with a sand pipe 2, a cylindrical cup 3 with an inlet 4 and a drain 5 -pipes and seal 6. In the cylindrical part of the body and cylindrical cup 3 identical holes 7 and 8 are made. in which a ring 10 with a ring gear 11 is placed with the possibility of rotation; in engagement with the screw 12. On the ring 10, with the help of tongs 13, limiting axial movement, screws 14 with actuators 15 are fixed. On the cylindrical part of the body there is a fixed disk 16 with holes 17 having threads similar to the screw 14 and holes under the free entry pins 8, which play the role of guides.

Hydrocycle works as follows.

Through the inlet 4 into the hydrocyclone serves tangentially initial mixture. In a rotating flow, separation into a light fraction occurs, which is removed along with the liquid.

through the drain pipe 5, and heavy through the sand pipe 2. During the hydrocyclone operation, it is necessary to adjust the operating mode, which is done by changing the shape of the cross section of the inlet pipe. To adjust the width of the inlet nozzle by means of a screw 12, it is rotated

ring 10, which with pins 18 rotates the disk 16 and with it the cylindrical body 1. The opening of the inlet nozzle is reduced in width, as it is blocked by the wall of the cylindrical body.

To adjust the opening of the inlet nozzle in height, the actuator 15 rotates

screws 14 that move the cylindonic housing 1 in glass 3 in the axial direction. At the same time, the height of the cylindrical part of the hydrocyclone changes, which leads to a corresponding change in the interconnected dimensions of the hydrocyclone elements. The height and width adjustment of the inlet spigot is achieved by simultaneous rotation and axial movement of the cylinder. cheskgo, buildings 1 with screws 14 and a worm pair (crown 11 and a screw worm 12).

The proposed hydrocyclone allows the inlet opening section to be smoothly adjusted in height and width by turning and axially moving the body in the glass, ensuring careful adjustment of the operation of the hydrocyclone. The simultaneous change of the hole in height and width allows you to select the desired shape of the flow section, which ensures careful adjustment.
