Description

The technical field to which the utility model

The utility model relates to the field of purification of natural and waste waters from the pollutants present in them, namely, devices for purifying natural and waste waters by filtering through filtering material. The device can be used to purify water of various origin from suspended solids, oil products, active chlorine, as well as to reduce the oxidation of water, water hardness, the content of heavy metals, to adjust the pH value. So to remove oil products, reduce oxidation can be applied loading from activated carbon or other material that absorbs these pollution. To reduce the rigidity and concentration of heavy metals, as well as boron, ion exchange resin can be used as a load. Calcite or another sorbent can be used as a charge for adjusting the pH value, reducing the concentrations of iron and manganese. The device has no restrictions on the use of other downloads. The device can be placed in blocks of tertiary treatment of water and sewage facilities, as well as water intake wells or sewer network wells. The device is intended to be used without maintenance until the exhaustion of the dirt-holding capacity and / or sorption, ion-exchange capacity of the filter material.

The level of technology

The known device for water purification, made in the form of a filter cartridge. Thus, the filter cartridge, patent No. 138499, published on March 20, 2014, has a cylindrical body filled with filter material / permeable bases, a flange and an eyelet for installation. The filtering cartridge, patent 156676, published 11.11.2015, has a cylindrical body filled with filtering material / permeable bases and a flange.

Known filter cartridge for water treatment / having a cylindrical body filled with filter material, the body has permeable upper and lower bases, the body in the upper part has a flange for attaching to the tank of purified water, while the side surface of the body is made permeable in the upper part above the flange . The flange is provided with lugs for slinging and moving the cartridge (RF patent for useful model No. 170818, B01D 27/00, published on 05/11/2017). Of the technical solutions known to the applicant, patent No. 171818 is the closest analogue to the claimed utility model. This patent has a set of features that are closest to the set of essential features of the claimed utility model: the filter cartridge for water purification has a cylindrical body filled with filtering material, the body has permeable bases, the body in the upper part has a flange for attaching to the filtered water tank, with This side surface of the housing above the flange is made permeable. The flange is provided with eyelets for slinging and moving the cartridge. The above-described analogues of the claimed model are based on the gravitational filtration of the purified water through the filter material “top-down”. Therefore, when water is filtered through these filter cartridges, a clogging of the upper part of the filtering material occurs (depletion of the dirt capacity of the upper part of the filter element). The degree of use of the filtering material of such filters is proportional to the area of the filtering surface to the volume of the filtering material. The disadvantage of all of the above devices is their uneven exhaustion of the soil-holding capacity and / or the sorption capacity of the filtering material, the insufficient degree of its use. An increase in the use of filter materials can be achieved by increasing the specific filter surface (the ratio of the filter surface per unit volume of the filter material).

Disclosure of the essence of the utility model

The objective of the claimed utility model is to design a filter cartridge that provides water purification with the highest efficiency of use of the filter material until it has exhausted its dirt-holding capacity or sorption capacity in the entire volume of the cartridge. The claimed technical result is achieved by the fact that the filter cartridge has an outer and an inner case, the space between which is filled with filtering material, the inner case forms an internal cavity for collecting filtered water, the side walls and the base of cylinders are permeable, and the inner cavity of the filter cartridge is attached to the tank purified water. The task of increasing the degree of use of filter materials is achieved by the fact that the filter cartridge has an internal case, the internal cavity of which is designed to collect purified water. The walls of the outer and inner housings are made permeable, the filter material is placed between the outer and inner housings, while the inner cavity of the filter cartridge is connected by a fitting (pipe) to the flange attached to the purified water tank. Filtration of the treated water is carried out "outside-in." The increase in the filtering surface in comparison with analogues leads to an increase in the degree of use of the filtering material.

Brief Description of the Drawings

FIG. 1 shows a view of the inventive filter cartridge, which presents the structural elements, the connections between them, as well as the mutual arrangement of the elements of the claimed device. External connections of the device with tanks to which it is attached and in which it is installed are also presented. Below is the designation of the elements of the filter cartridge, reservoir, source and purified water, as well as the direction of movement of the source and numerical water.

1 - source water tank;

2 - source water;

3 - outer permeable case of a cylindrical filter cartridge;

4 - cylindrical internal filter cartridge case;

5 - filter material placed in the space between the outer and inner housings of the filter cartridge;

6 - the internal cavity of the filter cartridge for collecting purified water;

7 - flange for connection to the reservoir of purified water 9;

8 - pipe for connecting the internal cavity of the filter cartridge 6 to the flange 7;

9 - tank of purified water;

10 - purified water:

11 - the direction of flow of the source water

12 - direction of discharge of purified water

Implementation of the utility model

The filter cartridge is installed in the source water tank 1. The filter cartridge is attached to the purified water tank by means of flange 7. Source water 2 enters the source water tank 1 for cleaning. Under the effect of the pressure difference in the source water tank 1 and the purified water tank 2, the source water passes through the permeable walls of the outer casing 3 of the filter cartridge, is filtered through the filtering material 5, and through the permeable walls of the inner casing 4 enters the internal cavity 6 of the filtering patr she is. From the inner cavity 6, the water 10 purified on the filter material 5 goes through the pipe 8 to the purified water reservoir 10. The device makes it possible to uniformly use the dirt-holding capacity and / or sorption capacity of the filter material, since the specific filtration area of the filter cartridge made by the claimed technical solution is maximum for cylindrical filters. A higher value of the specific filtration area may be at the spherical filter. Therefore, the inventive filter cartridge provides water purification with the highest efficiency of use of the filter material until it has exhausted the dirt capacity or sorption capacity in the entire volume of the cartridge. In the case of clogging of the filtering material of the upper part of the filter, filtration is carried out through the side surface or the lower base until the filtering material has completely exhausted the dirt-holding capacity and / or sorption capacity.
