The invention relates to a technique for purifying water from petroleum products and mechanical impurities and can be used in the chemical, petrochemical, and other industries for purifying oil-containing water.

A known filter for cleaning liquids, comprising a housing with nozzles, a filter cartridge made of a filter element and a spring frame.

The disadvantage of the known filter is its low efficiency and the need for frequent disassembly, which limits its use.

The closest known technical solution in its essence and the effect achieved is a filter for cleaning a fluid, comprising a housing with inlet and outlet nozzles and a filtering element made of an elastic material with a spring frame fixed on the ends of the washer frame, one of which is installed with the possibility of returning - translational motion and is in contact through the rod with the cam mechanism, and the second is fixed to the outlet nozzle.

In the known filter, the regeneration of the filter element is carried out by backwashing the liquid remaining in the cavity of the filter cartridge by compressing the spring with a cam mechanism. However, the quality of regeneration remains insufficient due to the fact that the material of the filter element undergoes compression to a small extent when the element is deformed in the longitudinal direction due to the absence of an enclosing outer partition, which does not ensure sufficiently complete removal of solid sediment and oil products from its pores. In this case, the washing is carried out in one compression cycle with a small volume of liquid in the cavity of the cartridge.

The purpose of the present invention is to improve the quality of regeneration.

The goal is achieved by the fact that a filter for cleaning a fluid, comprising a housing with inlet and outlet nozzles and a filtering element of elastic material, mounted on a spring frame, connected by its ends with washers, one of which is fixed to the outlet

the pipe, and the second is installed with the possibility of reciprocating movement and is in contact through the rod with the cam mechanism, is provided with an additional spring covering the filtering element, which is connected at its ends with washers and made with the winding opposite to the winding of the spring frame, which together with the filtering element and the additional spring has the shape of a truncated cone, a smaller base directed toward the outlet nozzle, and a nozzle with an internal screw groove and placed in it with your finger, radially mounted on the rod, it is advisable that at the outlet nozzle was installed pipeline with a valve for supplying the washing liquid.

Comparison of the proposed filter with known shows that filters with backwash of filter elements are widely used in the technique, however, in the proposed filter, the filter element is made with a frame in the form of a truncated cone with a smaller base on the side of the outlet nozzle, limiting the outer surface of the filter element by a conical spring fixed along the ends on the said washers, making the spring with opposite winding, fastening to the body, coaxially with the stem, branch pipe with an internal screw groove, azmeschenie in her fingers, radially fastened to a rod, and the supply duct outlet with valve I for supplying the washing liquid the filter impart new properties, increased efficiency of regeneration due to the longitudinal and transverse urging the filter element under simultaneous flushing.

FIG. 1 shows the proposed filter, a general view; in fig. 2 is a section A-A in FIG. one.

The filter includes a housing 1 with an inlet 2 and an outlet 3 with nozzles and a filtering element 4 of elastic material, for example, foam rubber stuffing of synthetic fibers, a spring frame 5 and a cam mechanism 6, the washer 7 is installed with the possibility of reciprocating motion and is in contact with the cam shaft 8 mehanitma b.

Lena to the outlet nozzle 3. The filter element 4 with a spring frame 5 is made in the form of a cone with a smaller base on the side of the outlet nozzle 3.

The outer surface of the filter element 4 is bounded by a conical spring 10, one end of which is fixed to the washer 7, and the second end to the washer 9. The springs 5 and 10 are made with opposite winding. Coaxially to the rod to the housing 1 is attached a pipe 11c1 with an internal screw groove 12 with a finger 13 placed therein, radially mounted on the rod 8. It is advisable that the outlet nozzle 3 be equipped with a pipe 14 with a valve 15 intended to supply the washing liquid.

The upper part of the housing 1 is provided with a pipe 16 for removal of petroleum products, and the lower part with a pipe 17 for removing mechanical contaminants.

The filter works as follows.

Water containing petroleum products and mechanical impurities is fed through pipe 2 into the housing 1, where it is filtered through filter element 4 and out through pipe 3 to the consumer or for further processing.

During the operation of the filter, mechanical impurities in the form of solid sediment gradually accumulate in the filtering element 4, and the oil products partially float up into the upper part of the housing 1 and are removed through the nozzle 16. As the flow resistance reaches the calculated values, the filter is regenerated.

For this, the pipes 2 and 3 overlap and the pipes 16 and 17 are opened. The cam mechanism 6 is actuated, which, when rotated, moves the rod to the side of the outlet pipe 3. At the same time, the finger 13 slides along the screw guide 12 and rotates the rod 8.

The springs 5 and 10 are compressed, and from the rotation of the washer 7, the spring 5 simultaneously spins up, while the spring 10 twists as these springs have opposite winding. With this, the diameter of the spring 5 increases, and the springs 10 decreases,. , which leads to the compression of the filter element 4 in thickness while compressing it simultaneously in the longitudinal direction

. The solid precipitate is squeezed out of the pores of the filter element and removed. through the pipe 17, and the pressed oil product float up and out through the pipe 16. At the same time, the fluid in the spring cavity is squeezed through the filter element 4 and flushes its pores from the solid sediment and oil products.

With further rotation, the cam 6 comes out of contact with the rod 9. Under the action of the springs 5 and 10, as they are being opened, the rod 9 again extends and rotates in the opposite direction, and the thickness of the filter element 4 increases. Then, if necessary, repeat the process of squeezing the filter element.

In case of heavy water contamination, the filter element is depressed with simultaneous supply of the washing liquid and when the springs 5 and 10 are stretched, the washing liquid with the valve 15 open enters the cavity of the filter element and washes its increase from stretching - pores.

When the springs 5 and 10 are compressed, the pressure of the flushing fluid in the cavity of the filter element increases and becomes larger than in the pipe 14, which causes the valve 15 to block the pipeline 1 and prevents the flushing liquid from being squeezed back into the pipeline 14. This contributes to the washing of the pores of the filter element 4 under high pressure that increases the efficiency of regeneration.

The technical and economic efficiency of the proposed filter in comparison with the known ones consists in increasing the efficiency of its regeneration by squeezing the filter element simultaneously in the longitudinal and transverse directions while simultaneously washing under high pressure due to the conclusion of the filter element between the outer and inner conical springs with opposite winding and the supply of the rod device for its loading during reciprocating movement.
