Abstract

The invention relates to liquid cartridge filters and can be used to purify seawater before desalination plants, as well as natural and waste waters. The purpose of the invention is to increase the efficiency and reliability of the filter. The filter consists of a support frame 1, bottom 2, connecting flange 3 with outlet 4, o (J ate J

Description

filtering grate 5, made in the form of a package of corrugated rings 6 installed one above the other, The difference of the filter is that the corrugations on the rings 6 are made at angle 1

The invention relates to filtration, namely to cartridge filters, and can be used, for example, to filter sea water before desalination plants, to filter natural waters before ion treatment of water, and also to clean wastewater.

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

Figure 1 shows the filter, a general view; figure 2 is a section aa in figure 1 on fig.Z - corrugated ring filter.

The filter consists of a support frame 1, bottom 2, connecting flange 3 with the outlet nozzle 4, filtering grate 5, made

the form of a package of installed each

another of the corrugated rings 6, a tension device, including a rod 7 passing through the frame, connected to the bottom 2 by nuts 8, a spring 9 and an adjusting nut 10.

The corrugations 11 of the ring 6 are made at an angle to the radius of the ring, and when installed in a package each subsequent ring is installed with the opposite direction of the corrugation relative to the previous ring (Fig. 2, dashed line). The corrugations of adjacent rings intersect. By turning the adjusting nut 10 it is possible to change the force. Compress the rings in the bag and thereby select the necessary clearance for filtering, and by reducing the compression of the bag, improve its regeneration. To protect the corrugated rings

from mechanical damage, protective rings 12 are installed on the frame;

The filter works as follows.

scrap to the radius of the ring, and when installed in the package, each subsequent ring is installed with the opposite direction of the corrugation relative to the previous ring, 1C. f-ly, 3 ill.

Untreated water flows to the outer surface of the filtering grid 5 and, penetrating through the gaps between the corrugated rings, enters their internal cavity, from where it flows through the channels of the frame to the outlet nozzle. Mechanical contamination is trapped on the surface of the grid and in the gaps between the rings.

The regeneration of the filtering grate is carried out by a reverse current of the filtrate.

At the same time, under pressure of the filtrate to the bottom 2, the spring 9 is stretched, freeing the rings and increasing the gap between them, improving the conditions for the removal of contaminants.

The filter can work in automatic mode.

The invention allows to increase the efficiency of cleaning liquids and the reliability of the filter.
