Description

The inventive utility model relates to a device for purifying a liquid by filtration using a sorption process, in particular, to produce drinking water and can be used in process water treatment systems for various industries, for domestic use, as well as in the field.

One of the main components of various liquid purification systems is replaceable filter elements, called either cartridges or cartridge filters. According to the description of the proposed device options relate to sorption cartridge filters, and more specifically to replaceable filter elements-cartridges of these filters used in flow systems for cleaning liquids by the dead-end filtration method.

Known portable filter for drinking water purification, containing a housing in the form of a funnel, a drainage grate with a packet of filter elements made of activated carbon fiber material placed on it and a means for reducing the porosity of the peripheral part of the filter elements, while a part of the housing or drainage grate located below the tool is waterproof [Pat. RU 2066301, IPC C02F 1/18, B01D 24/22, 09/10/1996].

A disadvantage of the known portable filter is the material from which the filter elements are made, which does not provide microbiological purification of water, as well as insufficient purification from heavy metals, since carbon sorbents are more suitable for sorption of organic pollutants.

Known country filter "Dolphin-D-3,5." The cottage filter is designed for cleaning metals, nitrates, nitrites, pesticides, organochlorine compounds, chlorine and other water from wells, wells used for drinking. The cottage filter provides for the possibility of systematic washing of a removable cartridge located in the inlet of the filter, as well as a removable block of filter elements located in this cartridge, designed to purify water from mechanical impurities and consisting of a set of layers of porous filter cloths located between two perforated synthetic gaskets material. A drainage tube made of synthetic material passing through the center of a set of filter layers and perforated gaskets is also a handle for removing a removable block of filter elements from the filter when washing it [Pat. RU 2146962, IPC B01D 24/12, C02F 9/00, 03/27/2000].

The known device is not intended for microbiological purification of liquids.

Known cartridge filter element [US Pat. RU 60874, IPC B01D 27/06, 02/10/2007]. Two variants of the cartridge filter element are proposed, the first version of the cartridge filter element contains a perforated tube and a layered filter material formed around it, connected by end parts, the filter material formed around the perforated tube in the form of a cylindrical roll, made in the form of a “sandwich”, the lower and upper layers which are synthetic non-woven material that freely passes water, between which there is an inner layer of sorption material n based fibrous sheet material of organic or inorganic origin, intended for fine-water purification and water purification from microorganisms, wherein the inner layer is formed as a smooth belt formed of a plurality of layers of the sorption material. The second version of the cartridge filter element contains a perforated tube and a layered filter material formed around it, connected by end parts, the filter material formed around a perforated tube in the form of a cylindrical roll, made in the form of a “sandwich”, the lower and upper layers of which are synthetic non-woven material, freely water-permeable, between which there is an inner layer of sorption material based on a fibrous sheet material of organic or ganic origin, modified nanoscale particles of alumina hydrate, intended for fine-water purification and water purification from microorganisms, wherein the inner layer is a corrugated tape formed of a plurality of layers of the sorption material.

This cartridge element is effective for cleaning microorganisms, but does not allow sufficient purification of liquids from heavy metals.

The closest in technical essence and result to the proposed device is a cartridge for cleaning liquid, containing a perforated frame, formed around it in several layers of sorption-filtering material, including at least two layers of protective material and placed between them a multilayer sorption material that supports an element worn over a sorption-filtering material and a glass with loading from a sorbent of heavy metals, mounted inside and on the same axis with a perforated frame m are connected end parts [Pat. RU 87365, IPC B01D 27/04, B01D 27/08, B82B 1/00, 10/10/2009].

The disadvantage of this device is the susceptibility to clogging of the pores of the sorption material with mechanical impurities, which leads to a rapid decrease in the efficiency of the cartridge.

The objective of the proposed technical solution is to develop a replaceable cartridge with a high degree of purification of the liquid from mechanical and harmful impurities.

Effect: increase the productivity of the filtering process and increase the degree of purification of the liquid.

The technical result is achieved by the fact that the cartridge for cleaning liquid contains a coaxially mounted glass with loading from a sorbent of heavy metals, a perforated frame, a sorption-filtering material, comprising at least two layers of protective material and a multilayer sorption material placed between them, and supporting an element connected by end parts, while the supporting element is made in the form of an elastic tubular knitwear of plush weave.

The manufacture of a supporting element from elastic tubular knitwear of plush weave due to the presence in the weave structure of an elastic skeleton of an elastomeric thread provides support for the inner layers of the cartridge. At the same time, the presence of plush loops ensures the capture of mechanical impurities, thereby protecting the inner layers from clogging of the pores and carrying out preliminary cleaning of the liquid. In addition, the implementation of the supporting element in the form of elastic tubular knitwear plush weave allows the regeneration of the supporting element. Due to this, there is an increase in the productivity of the filtering process and an increase in the degree of purification of the liquid.

In FIG. 1 shows a diagram of a cartridge for purifying a liquid; FIG. 2 is a graphical representation of a plush weave elastic tubular knit.

The liquid cleaning cartridge contains a perforated frame 1 made of polyethylene, polyamide, polypropylene or other food grade thermoplastics, on which a multilayer filter material is formed in the form of a cylindrical roll of at least two layers of sorption-filter material 2 prefabricated in the form of " sandwich ”, with an internal sorption layer 3 placed between two protective layers 4 made of synthetic non-woven material (polyethylene, polyamide, or polypropylene).

Inside the perforated frame 1, a cup 5 is placed on the same axis with it, loaded with a heavy metal sorbent 6. On top of the load 6, a retaining perforated element of polymer material 7 is installed.

On the sorption-filtering material 2 with the inner sorption layer 3 and the protective layers 4 is put on a supporting element 8, made in the form of an elastic tubular knitwear plush weave.

End parts 9 located at the ends of the cartridge, mechanically connected with the perforated frame 1, do not allow sorption-filtering material 2 to move along the perforated frame 1 and serve to attach the cartridge to the filter holder.

An elastic tube knitwear of plush weaving consists of loops formed by simultaneously knitting inextensible threads 10, forming plush loops 11 and elastomeric threads 12, forming an elastic frame 13.

Elastic tubular knitwear for plush weaving is obtained on a class 14 hosiery machine with a cylinder diameter of 4 ". The tension when feeding an inextensible thread into the loop forming system is 8.2 N, and the elastomeric thread 22.4 N with a cooler depth of 9.4 mm.

The cartridge for cleaning liquid works as follows: the cartridge is mounted in the seat of the filter holder. Filtered liquid supplied to the filter holder body passes through a supporting element 8 made in the form of an elastic tubular knitwear of plush weave. At the same time, plush loops 10 trap mechanical particles located in the filtered fluid, performing its preliminary mechanical cleaning and preventing

clogging the pores of the sorption-filtering material 2. This ensures more efficient operation of the cartridge. Next, the liquid to be cleaned passes through the sorption-filtering material 2, where in the inner sorption layer 3 electrokinetic retention of negatively charged particles - bacteria and viruses occurs, then through the perforated frame 1 the liquid to be cleaned enters the space between the frame 1 and the glass 5. Through holes in the lower part cup 5, the liquid passes inside the cup 5 from the bottom up through the load of the sorbent of heavy metals 6, then through the outlet of the filter holder gets to the consumer.

An example of the manufacture of a cartridge for cleaning liquid.

A sorbent of heavy metals 6 is loaded into a glass 5, made with holes in the lower part. As a sorbent of heavy metals, for example, aluminum oxide monohydrate modified with nanosized particles of iron oxides can be used to remove iron, arsenic, cadmium, lead and manganese; a mixture of ground zeolite, iron hydroxide and nanophase boehmite - for cleaning from arsenic, chromium, cadmium, copper and lead, modified humic acids - for cleaning from iron, chromium, manganese, cobalt, zinc, titanium, nickel and copper, hydroxide based sorbents magnesium, iron and aluminum - for cleaning copper, cadmium, zinc and lead.

A perforated element made of polymer material 7 is mounted on top of the sorbent of heavy metals 6. A glass 5, loaded with a sorbent of heavy metals 6, is placed inside the perforated frame 1, coaxially with it, with the formation of a gap between their cylindrical surfaces. The perforated frame 1 can be made of polyethylene, polyamide, polypropylene or other food grade thermoplastics. Separately, the sorption-filtering material 2 is prepared, made in the form of a “sandwich”, with an internal sorption layer 3 placed between two layers of protective material 4.

Sorption layer 3 can be made of sorption material based on particles of alumina hydrate modified by a non-woven polymeric fibrous material with a fiber diameter of 1-3 μm, or based on a Petryanov filter-15-2.0 filter, which is a uniform layer of ultra-thin fibers with an average diameter 1.5 microns deposited on gauze. The protective material 4 is made of synthetic non-woven material (polyethylene, polyamide, or polypropylene).

A multi-layer filter material in the form of a cylindrical roll is formed from a sorption-filtering material 2 made in this way, by winding it in at least two layers.

On the sorption-filtering material 2 with the inner sorption layer 3 and the layers of the protective material 4 (i.e., a multilayer filtering material formed in the form of a cylindrical roll), a support element 8 is made in the form of an elastic tubular plush knitwear. After that, using the end parts 9 fix all the "layers" of the cartridge. The ready-to-use cartridge is mounted in the seat of the filter holder.

The filtered fluid supplied to the filter holder body passes through the supporting element 8, which provides additional purification of the liquid from mechanical impurities. The liquid to be cleaned passes through the outer layer of the protective material 4, sorption-filtering material 2, where in the inner sorption layer 3 there is an electrokinetic retention of negatively charged particles - bacteria and viruses, and the inner layer of the protective material 4. Through the perforated frame 1, the liquid to be cleaned enters the space ( the gap) between the frame 1 and the glass 5, from where through the holes in the lower part of the glass 5 the liquid passes inside the glass 5 from the bottom up through the load of the sorbent of heavy metals 6, then through The outlet of the filter holder reaches the consumer.

Thus, the implementation of the supporting element in the form of an elastic tubular knitwear of plush weave allows you to increase the performance of the filtering process and to increase the degree of purification of the liquid.
