The invention relates to filtering, in particular to vibration filters for the purification of liquids from mechanical impurities, and can be applied in various sectors of the national economy.

The purpose of the invention is to increase the filter performance by removing contaminants from the filtering zone and reducing the hydrodynamic resistance.

 The drawing shows the proposed filter, a general view.

The filter consists of a cylindrical housing 1, an inlet 2 and an outlet 3 nozzles, a nozzle 4 draining sludge. Inside the housing 1 is installed filter element 5, for example, corrugated. Concentric to the filter element 5 is installed a casing 6. The filter element 5 is rigidly connected with the rod 7 of the vibrator 8. Springs 9 and 10 are installed on the rod 7 to create oscillatory movements. In the upper part of the housing G is installed 11 with a seal 12 for the rod. At the lower end of the filter element 5, an additional fi e element 13 is installed of the same filtering fineness as the main one. Below the additional filter element 13, an annular partition 14 is rigidly connected to the housing 1 with concentrically arranged openings 15 and a central opening 16,. in which the annular guide 1.7 is located, which is connected with the additional filter element 13 by means of a tapered adapter 18.

In the holes 15, the partitions 14 are mounted on the springs 19 with check valves 20. Bottom is isolated

The part 21 of the housing 1 is tapered and ends with the pipe 4 of the sludge discharge with a crane 22.

The filter works as follows.

The filtered fluid under pressure enters the filter housing 1 through a cut pipe 2, passes through the main filter element 5 and through the inside of the Rod 7 and the holes in it is removed from the filter through the pipe 3, under the action of the vibrator 8, the fidroelement 5 makes reciprocating movements as a result, due to the pulsating fluid flows along the filter element and through its pores, the delayed contaminants are strayed from it. In addition, when the filter element 5 moves upward in the lower part 21 of the housing 1, a vacuum is created, as a result, the valve 20 is displaced downward and a part of the liquid, together with the contaminants weighed in it, through the holes 15 enters the lower insulated part 21. passes to the lower part 21 through an additional filter element 13, simultaneously clearing it of contaminants.

When the filter element 5 moves downward in the lower part 21 of the housing 1, an increased pressure is created, whereby the valves 20 block the openings 15 and the liquid from the lower part 21 enters the inside of the main filter element 5 only through the additional filter element 13 and this is filtered.

Thus, with repeated vibrations of the filter element 5, contaminants are removed from the filtering zone located above. the baffles 14, to the lower part 21, from where the above contaminants are periodically removed from the filter through the nozzle 4. At the same time, the regeneration of the additional filter element 13 occurs. As a result, the main filter element is less soiled and, therefore, the hydraulic resistance decreases mesh, and this, in turn, leads to an increase in filter capacity. The invention allows to increase the filter performance by approximately 10%,
