Description

(54; GIDROSCHNSLON

The invention relates to devices for separating suspensions and can be used in mining, chemical, fir and other sectors of the B1 range, for example, in drilling oil and gas wells to clean drilling equipments from cuttings.

A hydrocyclone is known, which includes a cylindrical housing with a tangential feed pipe of the initial suspension, a drain pipe, a sand fitting and a device for eliminating driving blocked in the form of a rod centrally located in the cavity of the hydrocyclone and connected with an electromagnetic actuator ij.

The disadvantage of this hydrocyclone is the low efficiency of removal of the solid phase, due to the fact that the location of the device for removing clogging inside the song choke leads to an increase in the resistance c. .

The closest in technical essence and the achieved result to the invention is a hydrocyclone containing a cylindrical body with a tangential inlet nozzle, a drain nozzle and Peskovoy

a pipe with a device for removing its blockage. The device for preventing the clogging of the sand pipe is made in the form of a hydraulic cylinder with Eestem, and has a concave work surface whose radius is equal to the radius of the sanding nozzle 12.

The main disadvantage of the known hydro-slx is the low solids removal efficiency. During the operation of the hydrocycpone in rapidly changing conditions, it is necessary to control the diameter of the sand choke. The inoperability of the control leads to the frequent clogging of the sand nipple with the solid phase in the initial suspension.

The aim of the invention is to increase the removal efficiency of the solid phase during the operation of hydro-tilt under drastically changing conditions.

The goal is achieved by the fact that the hydrocyclone content

25 Cylindroconic case with tangential inlet nozzle, drain nozzle and Peskov nozzle with a device for preventing its blockage, equipped with a supply agent of the cleaning agent with axial holes connected to the inner corpus of the body concentrically installed to the corus, in the form of spring-mounted conical plates pivotally connected to the body, interconnected by elastic membranes forming a cone, with sand patra approx adapted spring-loaded and mounted for axial tseremescheni. FIG. 1 shows the lower part of the hydrocyclone, general view; in fig. 2 shows section A-A in FIG. one; on fig.Z - section bb, on fig, 1. A hydrocyclone consists of a cylindrical shell, which includes a fixed upper part 1 and a movable sand pipe 2. For supplying the initial suspension, a tangential cutting code is provided, and a drain pipe (not shown) for removal of the purified liquid. The solid phase is removed through a sand outlet. The sand patrubo is equipped with a device for eliminating its blocking, made in the form of connected h: Through a hinge 3c, the lower part of the body 2 of the conical plates 4, connected to each other along elastic forming membranes 5 forming the cone. The plates are pressed by means of springs i b. Concentric to the housing. The movable sand coupling 2 is made up of chambers 7 for supplying a cleaning agent. which is connected to the inner cavity of the hydrocyclone axial holes 8. The axial holes 8 are blocked by an axially movable axially sand pipe 2, pressed against the stationary part of the housing 1 by means of springs: 9. The pipe 10 is used to feed the cleaning agent into chamber 7 in the following way. The initial suspension is introduced into the gyro-cyclone through a tangential nozzle. Under the action of centrifugal forces, the suspension is separated. The clear liquid is discharged through the merger pipe, and the solid phase through the sand cartridge. If the percentage of the solid phase is increased in the initial suspension, it accumulates in the lower part of the hydrocyclone. Under the weight of a solid, the conical plates 4 move apart, increasing the cross section of the sand nozzle, which contributes to the rapid removal of the solid phase from the hydrocyclone, obstacles em clogging it up. If in the initial suspension Contains a significant amount of solid Lazy, which does not manage to be discharged through the maximum possible passage section, then under the influence of the weight of the accumulated solid phase the lower part of the body is lowered, chamber 7 communicates with the internal cavity of the hydrocyclone, and through the opening 8 into the hydrocyclone enters under pressure cleansing agent, which contributes to the intensive removal of the solid phase through the sand pipe. As a cleaning agent, you can use a liquid or gas (for example, water, air or steam), which is supplied to chamber B via supply pipe 10. When the concentration of solids decreases, the lower part of the housing -2 under the action of springs 9: returns to its original position and overlaps hole 8. Under the action of springs b, conical plates converging e c, reducing the cross section of the sand nipple. Refining a hydrocyclone with a concentric chamber for supplying a cleaning agent that is connected with the inner cavity of a hydrocyclone by axial holes , overlapping movable and spring-loaded in the axial direction of the lower: part of the housing, and the device for. Eliminating the driving of the sand Pipe in the form of spring-loaded conical plates hinged to the body and connected to one another by forming cone elastic membranes will increase the efficiency of removing the solid phase from the hydrocyclone during operation in drastically changing conditions and eliminate the sand pipe clogging. The operational control of the flow area of the sand nozzle will improve the quality of the separation of suspensions.
