Abstract

The invention relates to devices for the purification of liquids and permits an increase in the efficiency of self-regeneration of filter elements. The device consists of a housing 1 with channels for introducing fluid 3 and a filtrate outlet 4. Inside the housing, on the hollow shaft 5, disk filter elements 7 are installed between the supports 6 having radial holes (PO) II, inside the supports are inserts 8 with axial holes 9 and PO 10 rigidly connected to the hollow shaft 5. The inserts are mounted with the possibility of combining the PO 10 with the PO 11 of the supports 6. When the holes of the inserts and the supports cope, the high-pressure liquid rushes into the housing 1 along the filter surfaces at high speed nyh elements that provides effective self-regeneration of the filter elements. 2 Il. with P

The invention relates to devices for the purification of liquids and can be used in all areas of the industry where cleaning of liquids is required.

I The purpose of the invention is to increase the efficiency of T1 | self-regeneration of filter e.ements.

i FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 is a cross section A-A in FIG. one.

; The device consists of body 1, cover 2) with inlet channels 3 for liquid and output 4 for filtrate, perforated shaft 5, mounted in supports 6, crepe ихix to the body, disk. filter elements / t mounted on the shaft in the gaps | ezhdy supports, inside the supports there are rates 8, rigidly connected to the shaft, axial 9 and 10 radial holes are made in the inserts, and radial holes 11 are made in the supports with the possibility of radial holes with inserts when rotating the shaft.

The device works in the following way.

The shaft 5 with the aid of a drive (rotation is not shown). The fluid to be cleaned is supplied through the inlet channel 3 to the inside of the hollow shaft -5, then to the radial holes 10 of the insert. Next, the liquid is fed into the body at the moments when the radial holes of the insert during rotation with radial holes of the supports 11. Then, the liquid passes through the filtering surface of the disk filter elements 7, and the filtrate is discharged through the axial holes 9 of the inserts and channel 4.

Yes, the holes of the inserts and the supports do not coincide, the fluid is not supplied to the filter elements 7, the contamination is not affected by pressure, pressure drop, which presses them to the screen, and the contaminants come off the screen under the influence of centrifugal forces arising during rotation. In the same period of time inside the hollow shaft, the pressure created by the feed pump (not shown) increases. In the next period of time, when the holes of the inserts and the supports coincide, the liquid under high pressure rushes into the body at high speed along the surfaces of the filter elements, which also ensures the effective flushing of contaminants from the filter surfaces. Then the cycle repeats.

The contaminants removed from the surface are deposited in the bunker, from where they are discharged through the sludge outlet pipe.
