Abstract

The invention relates to devices for cleaning liquids from mechanical impurities in the field of centrifugal inertial force and allows increasing the efficiency of sludge trapping and increasing operational reliability. The proposed device contains a vortex chamber 1 consisting of a supply 2 and a discharge 3 pipelines connected to form an inlet tangential slot 4, a cylindrical insert 5, a pressure hydrocyclone 6 with an inlet 7, a drain and a slurry nozzle. The drain pipe is connected by a pipe 10 to the axial zone of the vortex chamber 1, and the inlet pipe 7 is equipped with a valve 12 and is tangentially connected to the cavity 13. The liquid to be cleaned flows into the body of the vortex chamber 1 through the tangential gap 4 and twists. The purified liquid enters the discharge pipe 3. The contaminated liquid from the cavity 13 enters the pressure hydrocyclone 6 through the pipe 7, where the pollution is concentrated and removed from the device. The clarified liquid enters the axial zone of the vortex chamber 1 via pipeline 10. 3 Il.

Description

The invention relates to devices for cleaning liquid from mechanical impurities in the field of centrifugal force of inertia and can be used in hydraulic engineering, chemical, mineral processing and other industries.

The purpose of the invention is to increase the efficiency of trapping sediment and increase the reliability of operation.

Fig; 1 shows a device, a general view, a longitudinal section (in Fig. 2 - section A-A in Fig. 1; in Fig. 3 - section BB in Fig. I.

The device contains a vortex chamber I, supplying 2 and discharging 3 pipelines. The inlet pipe forms, with a vortex chamber of 1 ton, an ngential slit 4. The device also contains a cylindrical insert 5, a pressure hydrocyclone 6 with an inlet 7, a drain 8 and a pulp 9 nozzles. The drain pipe 8 is connected by pipelines 10 to the axial zone of the vortex chamber 1 through opening II at the end of chamber 1, and the inlet 7 is equipped with a valve 12 and connected tangentially to the annular cavity 13 bounded by the wall of the cylindrical insert 5 and the body of the vortex chamber I. Inlet pipe 2 is located parallel to the axis of the vortex chamber 1, the cylindrical insert 5 is placed at the output end of the vortex chamber i with the formation of an annular cavity 13, and the discharge pipe 3 is attached to the cylindrical insert 5 and is coaxially aligned roar camera 1.

The device works as follows.

When passing contaminated fluid through conduit 2, a device for trapping sludge is connected;

This tangential slit H forms a screw movement in the vortex chamber 1 with the formation of an air cord in the center and separation of suspended particles in the annular cavity 13 with the flow of pulp through the tangential inlet 7 into the hydrocyclone 6. Absorption of a part of the liquid by the central hole 11 leads to the intake of clarified liquid from the drain hydrocyclone nozzle 8 6. The contaminated liquid is removed through pulp nozzle 9 of the hydrocyclone 6.

The use of the proposed device for trapping sludge in pressure pipelines in comparison with the known ones provides a continuous process of cleaning the liquid, preventing silting and hydroabrasive wear of the pipeline, and improving the operational reliability of the pipeline.
