Description

The utility model relates to devices for purifying liquids by filtration using a sorption process and can be used in process water treatment systems for various industries, for domestic use, as well as in the field.

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 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, a 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.

A known cartridge for cleaning liquid, 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, made in the form of an elastic tubular knitwear by interlacing a tubular surface from simultaneously knitted carbon and elastomeric filaments and a multilayer sorption material placed between them, and a supporting element connected by end parts [Pat. RU 155031, IPC B01D 27/02, 09/20/2015].

The disadvantage of this device is its low efficiency when cleaning from organic compounds and petroleum products.

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 of elastic tubular knitwear by combined weaving of an eraser 1 + 1 from simultaneously knitted inextensible and lastomernoy yarns, wherein adjacent loops of the pulling thread disposed inextensible wales between the purl face and sides, and coats, knit on the front side eraser 10 in the loop of inextensible yarns series connected end parts [Pat. RU 171495, IPC B01D 27/02, 02/02/2017].

The disadvantages of these devices are their low efficiency when cleaning from organic compounds and petroleum products, as well as the low mechanical resistance of the supporting element to the strong pressure of the treated water.

The objective of the proposed technical solution is to develop a cartridge resistant to strong fluid flows with the possibility of additional purification from organic compounds and petroleum products.

Effect: increase the degree of purification of the liquid.

The technical result is achieved by the fact that the cartridge for cleaning the liquid contains a coaxially mounted cup connected with end parts with a sorbent loading of heavy metals, a perforated frame, a sorption-filtering material, including two layers of protective material and a multilayer sorption material placed between them, and a supporting element, made of elastic tubular knitwear with the combined weaving of an eraser 1 + 1 from simultaneously knitted inextensible and elastomeric threads, in which ki adjacent loops of inextensible yarns are wales between the purl face and sides, and coats, knit on the front side eraser 10 in the loop rows of inextensible yarns, while on the underside of an elastic tubular knitted fabric is porous rubber coating.

The implementation of the supporting element from elastic tubular knitwear by combining the 1 + 1 eraser from simultaneously knitted inextensible and elastomeric yarns, in which broaches of adjacent loops of inextensible yarns are located between the loop columns of the front and back sides provides more efficient capture of mechanical impurities due to the denser loop structure of the two-layer weave, and the presence of a surface knitted on the front side of the eraser in 10 looped rows of inextensible threads about espechivaet efficient solids capture, thereby protecting the inner layers (eraser) of pore plugging by performing prefilter function and allows for regeneration of the supporting member. At the same time, the execution of the support element of the porous rubber coating on the seamy side of the elastic tubular knitwear, in addition to cleaning the liquid due to the extremely dense hinge structure of the knit, provides additional cleaning due to the retention of small mechanical particles and hydrocarbon compounds in water. In addition, the porous rubber coating provides its own structural rigidity of the supporting element and the cartridge as a whole, performing the functions of a rigid supporting element, which provides more effective resistance of the cartridge structure to fluid flow.

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 shows the structure of the supporting element in the form of a graphic record of the combined weaving of the eraser 1 + 1 and the surface and the applied porous rubber coating.

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 two layers of sorption-filtering material 2 prefabricated in the form of a “sandwich”, with an inner a 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 as it is loaded with a heavy metal sorbent 6. A perforated retaining element made of polymer material 7 is installed on top of the load 6.

A support element consisting of an elastic tubular knit 8 and a porous rubber coating 9 made on the wrong side of an elastic tubular knit 8. An elastic tubular knit 8 of the support element is made by a combined weave of an eraser 1 on a sorption-filtering material 2 with an inner sorption layer 3 and protective layers 4 +1 of simultaneously knitted inextensible 10 and elastomeric 11 threads, in which broaches 12 of adjacent loops of inextensible thread 10 are located between the loop stitches with the foreheads of the front 13 and the wrong side 14, and the surface knitted on the front side 13 of the eraser in 10 looped rows of inextensible threads 15.

The end parts 16 located at the ends of the cartridge, mechanically connected with the perforated frame 1, do not allow the sorption-filtering material 2 to move along the perforated frame 1 and serve to attach the cartridge to the filter holder.

Elastic tubular knitwear is knitted on a class 14 hosiery machine. The interlacing of the eraser is knitted at the maximum distance between the needle beds, which ensures the formation of enlarged looped broaches 12 and 17 from inextensible 10 and elastomeric 11 threads. Then the needles of the upper cylinder turn off, holding the loops of the wrong side 14 of the eraser. The surface weave is knitted on the lower cylinder, ensuring the formation of folds 18 of the inextensible string 15. From each front loop of the eraser, the first row of smoothness begins and the smoothing of the smooth surface ends by knitting the last tenth loop. Thus, on the front surface of the tubular knitwear by weaving an eraser, in each row, transverse tubes are formed from the weaving of the surface, which form folds 18.

At the end of knitting the surface on the front loops 13 of the eraser, the needles of the upper cylinder are included in the work, knitting the loops of the eraser. After dropping the knitted eraser loops from the needle bar (end of knitting of the buttonhole series), the broaches 17 of the elastomeric thread 11 between the needle bars are reduced, which ensures the formation of additional columns of broaches 12 formed from inextensible thread 10. Thus, the loop structure is densified along the width of the weave. The cycle repeats in each loop.

In this case, at the end of knitting, a cylindrical knitted product is formed, containing a smooth surface on the outer surface of the fold 18.

A rubber mixture is applied to the underside of the obtained elastic tubular knit 8 by two-phase spraying followed by heat treatment, from which a porous rubber coating 9 is formed, together with an elastic tubular knit, forming a rubber-textile material.

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 support element made of elastic tubular knitwear 8 with a porous rubber coating 9. Moreover, the interweaving of elastic tubular knitwear 8 together with a porous rubber coating 9 provides a more efficient trapping of mechanical impurities and hydrocarbon compounds in water . In addition, the porous rubber coating increases the intrinsic rigidity of the support element and the cartridge as a whole. 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 of 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 multilayer 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 two layers.

On a sorption-filtering material 2 with an internal 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 of elastic tubular knitwear 8 is made, made in the form of a combined weave of an eraser 1 + 1 from simultaneously knitted inextensible 10 and elastomeric 11 threads, and smooth, knitted on the front side 13 of the eraser in 10 looped rows of inextensible threads 15, and a porous rubber coating 9 made on the back ary side elastic tubular knitted 8. Then via end pieces 18 are fixed all "layers" of the cartridge. The ready-to-use cartridge is mounted in the seat of the filter holder.

Thus, a cartridge for cleaning liquid, containing coaxially mounted cup connected with end parts with a sorbent loading of heavy metals, a perforated frame, a sorption-filtering material, including two layers of protective material and a multilayer sorption material placed between them, and a supporting element made of elastic tubular knitwear by combined weaving of an eraser 1 + 1 from simultaneously knitted inextensible and elastomeric threads, in which broaches of adjacent loops of nera the tightening threads are located between the looped columns of the front and back sides, and the surface knitted on the front side of the eraser in 10 looped rows of inextensible threads, with a porous rubber coating made on the wrong side of the elastic tubular knitwear, provides an increase in the degree of fluid purification while simplifying cartridge designs.
