Description

The invention relates to devices for cleaning liquids from dissolved and undissolved contaminants and can be used in water supply systems, sewage systems, in the chemical, mineral processing industry and in a number of other sectors of the national economy.

The purpose of the invention is to increase the degree of purification of the liquid.

The drawing shows a vibroactive hydrocyclone, a general view.

The vibro-active hydrocyclone contains a cylindrical housing 1 with a lid 2, a tangential inlet nozzle 3 and nozzles for draining filtrate 4, sludge 5 and floating impurities 6. Inside the case there is a filter element with cable 7 and an adjusting screw 8 installed in the filtrate tapping pipe. The filter element is provided with an external elastic ring 9 and is made in the form of springs 10 coaxially arranged one inside the other, covered with external 11 and internal 12 grids, the space between which is filled with a deformable chemically active material 13. Elastic nets are attached with their upper ends to the filtrate outlet and the bottom - to the closed conical end 14 of the filter element. The cell size of the internal grid is smaller than the external one.

Vibro-hydrocyclone works as follows.

The original fluid through the tangential inlet 3 enters under pressure into the housing 1 and acquires -intensive rotational motion. Under the action of centrifugal inertia forces, heavy particles of pollution move to the walls of the body and down a helical spiral trajectory to the lower part of the apparatus, where they are removed with a part of the liquid through the slurry nozzle 5, Floating contaminants are concentrated - in the upper part of the crack 2 and discharge through the pipe 6, Leaving the liquid through the external coarse grid 1 enters the zone of action of a highly active load, is cleaned here from the contaminants dissolved in it, is filtered through the small internal grid 12 and leaves hydrocyclone through pipe 4 of the filtrate outlet.

which prevents them from going through the inner screen 12, floating up or precipitating along with the load wear products, are returned to the hydrocyclone and removed, respectively, through nozzles 6 or 5.

Intensive rotation of the fluid in the hydrocyclone and the Venturi effect, manifested in the gap between the elastic ring 9 of the end 14 of the filter element and the body of the hydro cyclone, cause the filter element made in the form of coaxially arranged springs 10 in each other covered with grids self-oscillations relative to the point of suspension with elastic blows to the body. Math self-oscillations of the filtering element with loading in the vibro-impact mode provide a constant regeneration of the grids, loading and intensify the processes of mechanical and chemical cleaning of the fluid. The oscillation frequency depends on the flow rate. The amplitude is determined by the size of the gap between the end of the filter element and the housing and is adjusted by changing the position of the end by means of an adjusting screw 8 connected to it with a cable 7.

Thus, equipping the filter element of a vibroactive hydrocyclone with an elastic ring and making it coaxially arranged with springs covered with elastic nets, the space between which is filled with a chemically active load, allows an increase in the degree of purification of the fluid by combining both mechanical and mechanical and chemical cleaning. At the same time, the vibrations of the filter element and the reduction of shock loads on the body, obtained due to the spring design of the filter element with an elastic ring at the end, provide constant mixing of the load and regeneration of filter surfaces, intensifying the processes of mechanical and chemical cleaning, increasing the degree of purification of the liquid from contamination and improving hydrocyclone operating conditions
