Description

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

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 means made 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 intended for purification from 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.

A known cartridge for cleaning liquid, containing a perforated frame formed around it in several layers of sorption-filtering material, comprising at least two layers of protective material and placed between them a multilayer sorption material supporting element worn over the sorption-filtering material, and a glass loaded with a sorbent of heavy metals mounted inside and on the same axis with a perforated frame, connected by 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 closest in technical essence and result to the proposed device is a cartridge for cleaning liquids, containing a coaxially mounted glass with loading from a sorbent of heavy metals, a perforated frame, sorption-filtering material, comprising at least two layers of protective material and a multilayer placed between them sorption material, and a supporting element made in the form of an elastic tubular knitwear of plush weave, connected by end parts [Pat. RU 155030, IPC B01D 27/02, 09/20/2015].

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, containing 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 made of elastic tubular knitwear connected by end parts, while the elastic tubular knitwear of the supporting element is made by combined binding the eraser 3 + 1 from simultaneously knitted inextensible and elastomeric threads and smoothness, knitted on the front side of the eraser in 10 looped rows of inextensible threads.

The manufacture of a supporting element from elastic tubular knitwear by combining the 3 + 1 eraser and the smoothness knitted on the front side of the eraser provides support for the inner layers of the cartridge.

At the same time, the presence of a 3 + 1 eraser from simultaneously knitted inextensible and elastomeric threads provides a more efficient capture of mechanical impurities due to the denser loop structure of the two-layer weave, and the presence of a smooth knit on the front side of the eraser in 10 looped rows of inextensible threads provides a more efficient capture mechanical impurities, thereby protecting the inner layers from clogging pores, performing the functions of a prefilter. In addition, the implementation of the supporting element in the form of an elastic tubular knit with the combined weaving of an eraser 3 + 1 from simultaneously knitted inextensible and elastomeric threads and smoothness knitted on the front side of the eraser in 10 looped rows of inextensible threads 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. Figure 2 presents a graphical record of the combined weaving of the eraser 3 + 1 and the surface.

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

On the sorption-filtering material 2 with the inner sorption layer 3 and the protective layers 4 is put on a supporting element 8 of elastic tubular knitwear. The elastic tubular knit of the supporting element 8 is made by combined weaving of an eraser 3 + 1 from simultaneously knitted inextensible 9 and elastomeric threads 10 and smooth, knitted on the front side of the eraser in 10 looped rows of inextensible threads 11.

The end parts 12 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 tubular knitwear with a combined weaving of an eraser 3 + 1 from simultaneously knitted inextensible 9 and elastomeric 10 threads and smoothness, knitted on the front side of the eraser in 10 looped rows of inextensible yarns 11, is knitted on a double-loop knit machine of large diameter INTERLOCK 22 classes, by turning on one system loop formation for knitting an eraser 3 + 1 and ten systems in the lower cylinder for knitting by weaving a smooth surface. In this case, the needles of the rear needle bar are turned off from work, holding the loops on the wrong side of the eraser. Thus, from each facial loop of the eraser, the first row of the smooth surface begins and on it ends the knitting of the smooth surface by knitting the last tenth loop. At the end of knitting, the smooths on the front loops turn on the needles of the rear needle bar, knitting the loops of the eraser. The cycle repeats in each loop. Thus, on the front surface of the tubular knitwear with a 3 + 1 eraser, in each row, transverse tubes are formed from the weave of the surface, which form folds.

In this case, at the end of knitting, a cylindrical knitted product is formed, containing a smooth surface on the outer surface of folds 13.

The cartridge for cleaning liquid works as follows: the cartridge is mounted in the seat of the filter holder. Filtered fluid supplied to the filter holder body passes through a supporting element 8 of elastic tubular knitwear made by combined weaving of an eraser 3 + 1 from simultaneously knitted inextensible 9 and elastomeric 10 threads and smoothness, knitted on the front side of the eraser in 10 looped rows of inextensible threads 11 In this case, the dense folds formed on the outer surface 13 by the weaving of the surface retard the mechanical particles located in the filtered fluid, carrying out its preliminary fur cleaning, thereby protecting the inner layer of knitwear - the eraser - from clogging the pores (acting as a prefilter) and together with the eraser provides more efficient capture of mechanical impurities due to the denser loop structure of the two-layer combined weave.

Increasing the efficiency of trapping mechanical impurities prevents clogging of the pores of the sorption-filtering material 2. This ensures more efficient operation of the cartridge as a whole. 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 with a load of 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 polymer 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 ultrathin fibers with an average diameter of 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 a sorption-filtering material 2 with an inner sorption layer 3 and layers of protective material 4 (i.e., a multilayer filtering material formed in the form of a cylindrical roll), a support element 8 is made of elastic tubular knitwear made in the form of a combined weave of an eraser 3 + 1 from simultaneously knitted inextensible 9 and elastomeric 10 threads and smoothness, knitted on the front side of the eraser in 10 looped rows of inextensible threads 11. After that, using the end parts 12, fix all and "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 The outlet of the filter holder reaches the consumer.

Thus, the implementation of elastic tubular knitwear by combining the 3 + 1 eraser from simultaneously knitted inextensible and elastomeric threads and smoothness, knitted on the front side of the eraser in 10 loop rows of inextensible threads, allows to increase the filtration process productivity and increase the degree of liquid purification.
