The invention relates to devices for the continuous separation of suspensions into liquid and solid phases, in particular to vibration filters.

The purpose of the invention is to increase the efficiency of cleaning fluid and reliability of the filter.

The drawing shows a vibration filter, a general view.

Vibration filter consists of a housing 1 with nozzles 2-5, respectively, the supply of the original liquid, drainage of filtrate, light fractions and sludge. In case 1 there is a razmesh, eny is wrapped by a microgrid 6 filter element 7 and an exciter 8. The upper open end of the filter element 7 is attached to the branch pipe 3 of the filtrate by means of a microgrid 6, and the lower end is installed with the possibility of blocking the diffuser 9.

The vibration exciter 8 contains a diffuser 9 mounted at the outlet of the nozzle 2 for supplying the source liquid, a piston 10 with screw grooves 10 attached to the lower end of the filter element 7 and a return spring 11, the lower end of which is rigidly attached to the piston 10 and the filter element 7 and the upper one to the filtrate nozzle 3 . At the entrance to the vibration exciter 8, a trap 12 with a valve 13 is installed and a receiving screen 14 with a core 15, which is connected by a flexible coupling 16 to the valve 13 of a trap 12. The trap 12 is equipped with a spring 17, which core 15 is pressed against the piston 10 of the vibration exciter 8.

The vibrating filter works as follows.

The contaminated fluid through the pipe 2 supplying the source fluid enters the trap 12 and through the receiving grid 14 and the screw grooves of the piston 10 of the vibration exciter 8 passes into the diffuser 9. Under the action of excessive pressure on the ends of the filter element 7 and the piston 10, the liquid overcomes the force of the return spring 11, tears the diffuser 9 and enters the housing 1. The fluid pressure on the walls of the screw grooves of the piston 10 creates the last torque that occurs when the diffuser 9 is opened. As a result, the piston 10 and the filter element 7 associated with it, moving upward, they rotate around a vertical axis. When the piston 10 moves with the filter element 7 upward, the pressure in the diffuser 9 and under the piston 10 drops due to the opening of the diffuser 9 and the valve 13 of the trap 12. As a result, the piston 10 under the action of a return spring

The gland 11 rushes down, strikes the core 15, shakes the receiving grid 14 and, overcoming the force of the spring 17, closes the valve 13 of the trap 12 and the diffuser 9, after which the cycle repeats. In this way, vertical and angular oscillations of the filter element 7 and vibro-impact oscillations of the receiving screen 14 are provided, which promote the regeneration of the filter element and increase the efficiency of cleaning the liquid.

From the housing 1, the fluid purified using the microcell 6 of the filter element 7 is discharged through the nozzle 3 of the filtrate. Floating contaminants are removed through pipe 4 for discharging light fractions, heavy soils are discharged through pipe 5 for discharging sludge.

The high-pressure pulsating flow flowing out from under the valve 13 of the trap 12 takes 12 heavy and large particles of contaminants out of the trap and contributes to the discharge of sediment from the nozzle 5 of the sludge outlet.
