The closest in technical essence to the claimed is

cartridge filter type, described in RT instructions for the use of Brit filter.

The well-known removable cartridge filter type sodermst is a hollow plastic casing, in the upper part of which there is a receiving grate for the liquid to be filtered, in the lower part - the bottom of the casing - an exhaust screen for the filtered liquid, and filter material consisting of granular material is placed between the upper part and the bottom in the cavity of the casing coal and ion exchange resin. The cartridge filter is inserted into a portable type-to-depth container, in which there is a transverse annular partition with a neck in the center of the latter, made in the form of a truncated cone directed with a narrower part down, and specially designed for this filter. The filter is replaceable. It is designed to filter 100 liters of drinking water, after which it must be replaced, because the filter material becomes dirty and ceases to perform the purification function. and it is impossible to replace it due to the performance of the case inseparable.

A disadvantage of the known filter is the need for periodic replacement, which has recently become expensive and economically disadvantageous, because the filter is disposable.

full use while ensuring the necessary degree of purification of drinking water.

This goal is achieved by the fact that in the removable cartridge type filter containing a hollow body, in the upper part of which there is a receiving grate for the filtered liquid, in the bottom there is an exhaust mesh for the filtered liquid, and filter material - adsorbing is placed in the cavity between the upper part and the bottom, including coal, ACCORDING TO THE USEFUL MODEL, in the upper part of the body a hole is made for a tightly fitting stopper, and the filter material is active in the form of crushed particles and is replaceable.

In this case, part of the activated carbon particles can be impregnated with silver.

In this case, the filter material can be placed in the cavity of the casing in the form of two layers - the upper one from crushed particles of coal impregnated with silver, and the lower one from crushed particles of coal.

In addition, Motug activated carbon particles should be mixed with an ion exchange resin.

In this case, the receiving grid can be a water-permeable membrane.

material, which makes it possible to make a cartridge filter reusable, and therefore cheaper.

Compared with the prototype, the inventive removable filter cartridge has a novelty, differing from it by the presence of such characteristic features as a hole for a tight-fitting plug in the upper part of the housing, which allows filtering material made in the form of crushed particles of activated carbon to achieve the desired value through it effect.

The inventive removable cartridge filter can be widely used for domestic drinking water treatment plants, therefore, meets the criterion of industrial applicability.

The utility model is illustrated in the drawing, which shows the appearance and sectional view of the inventive removable cartridge filter.

The removable cartridge type filter contains a housing I, in the upper part of which a hole 2 is made for a badly fitting plug 3 and there is a receiving grill 4 for the fluid to be filtered, an exhaust mesh 5 in the bottom and a filter cartridge 6 is placed between the receiving penieTk 4 and the bottom in the cavity of the housing 6 representing particles of crushed activated carbon, moreover, part of the particles can be impregnated with silver, and the filter material can be placed in two layers - the upper layer is made of silver-impregnated crushed coal particles, and the lower one is made of non-coated silver-fed crushed coal particles. The filter material 6 may consist of a mixture of ion exchange resin and crushed activated carbon. The intake grill may be a water-permeable membrane.

The housing 1 of the cartridge filter and the plug 3 can be made of materials that can be used in the food industry, for example, plastic.

The removable cartridge filter can be installed in any container of a suitable size using an installation device consisting of a transverse annular partition inserted into the specified container and having a neck with a corresponding tight fit of a diameter filter in the center.

A removable cartridge filter is used as follows.

The user inserts a cartridge filter into a neck specially designed for him in the shape of the filter housing in the annular transverse partition of a portable household appliance, for example, a jug-type appliance, where drinking water to be cleaned is poured with a temperature not exceeding 40 degrees Celsius. Water enters through the intake grill 4 into the cavity of the housing 1 and passes from top to bottom through the filter material 6. At the same time, the water is purified using an adsorbent - particles of crushed active carbon and its

additional disinfection in the presence of silver particles impregnated with silver in the filter material. The purified water through the outlet mesh 5 is discharged into a jug, from where it is discharged for consumption. An annular partition 7 in the jug and a snug fit of the filter to the cylindrical neck 8 provide isolation of the receiving upper part of the filtered water tank from the lower outlet of the filtered water tank.

After operating for 150 months or a fish consumption, the filter should be refilled with 150 liters of drinking water. To do this, the firefighter removes the filter from a portable household installation and hands it over to a special exchange point, from where it is transferred to a mini-workshop or a special laboratory. In the laboratory, the operator removes the plug 3 from the opening 2 of the housing 1 and removes the used filter material b. After that, the filter housing 1 or the housing of several filters assembled to replace the filter material is immersed in a water bath with a capacity of about 3 l (with a small cartridge filter size) or more (depending on the size of the filter) at a water temperature of 45-48 degrees, where detergents are added funds permitted for this purpose by the Sanitary Inspection, for example, 0.5 - 2% soda ash or liquid Progress. Then the housing 1 is cleaned externally and internally by mechanical cleaning, for example, using a brush of a suitable size and the housing is washed in the bath. Next, the housing 1, plug 3 and a funnel (not shown in the drawing)

to fill in fresh filter material, immerse in a bath of an analogous container, in particular, 3 liters of water with a disinfectant solution (for example, 3 4% hydrogen peroxide solution), where they are kept for about 0.5 hours. The disinfected housing 1, cork 3 and the funnel are removed from the solution and cured for 10-15 minutes on a clean special shelf-stand. Then, through the funnel introduced into the hole 2, fresh filter material b is poured into the cavity of the housing I in a volume of about 150 ml or more, depending on the size of the filter, using a measuring cup, visually controlling the loading volume - approximately to the middle of the top of the receiving grid 4 . As the filter material used crushed activated carbon, for example, grade BAU-MF (GOST 6217-74) and silver-impregnated active carbon grade BAU them. Ag (UAI) (TUB-16-2588-82) in a ratio of 1: 1. Housing 1 with fresh filter material filled into it b is tightly closed with a Stopper 3 by pressing it into housing 1. To remove the coal dust remaining after loading the filter, the corked housing is rinsed under running water at a temperature of no higher than 40 degrees Celsius using a brush, then install the filter vertically on a shelf-stand and let through for 1 hour. The finished filter is sealed in a plastic bag using a thermal pack. TO

they attach a passport and instructions for use. Pack a batch of ready-made filters in a plastic bag and send them to a retail outlet or exchange office.

The described cartridge filter of removable type can be manufactured by finalizing the used replaceable filter elements used in imported household filters for treating drinking water with the Brit, Kenwood models, etc.

To do this, in the upper part of the housing of the replaceable element of such a filter, a hole is drilled with a hand tool or a hole with a diameter of, for example, 12 mm is milled under a PPV-12 plastic plug. A drilled or milled circle is removed, for example, with tweezers. Then the spent filter material is unloaded and then the operations described above are performed, resulting in a cartridge filter, again suitable for use.

The filter 1 is the material material 6, used for operation in the inventive filter, allows you to purify Drinking water with the following effect:

-free and bound chlorine - up to 100%;

-nitrate content - up to 90%;

- iron and zinc - up to 97%;

-lead, aluminum, copper - up to 100%;

 .

γ-content - up to 55%, i.e. provides high quality

cleaning up.

The inventive cartridge filter of a removable type in comparison with the prototype can be used repeatedly and therefore cheaper, while ensuring the necessary quality of cleaning.
