Description

The inventive utility model relates to a device for purifying a liquid by filtration, in particular for producing drinking water (meeting the required standards) and can be used in water treatment systems for domestic use, pharmaceutical purposes, 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. Such filter elements are often made of non-woven materials, providing various types of filtration. According to the description of the proposed device options relate to ion-exchange and sorption cartridge filters, and more specifically, to replaceable filter elements-cartridges of these filters used in flow systems for purifying liquids by the dead-end filtration method.

Known [RU 2013104 C1, 1994] is a filter for cleaning liquids, the filter cartridge of which is made in the form of two coaxial glasses inserted one into the other. In the gap between the glasses there is a tubular insert ribbed on the inside and with holes in the lower part. An ion-exchange resin is placed in the annular space between the outer cup and the tubular insert, and activated carbon is placed in the inner cup. The ion exchange resin is constantly under the liquid inlet, which ensures the integrity of the resin and increases the reliability of the filter.

Known household filter for the purification of drinking water "Zeolite-S" [RU 2252061 C1, 2005], comprising a housing with inlet and outlet nozzles, vertical partitions installed inside the housing with the formation of blocks for sorbents, while the partitions are made in the form of two cylinders installed coaxially along the vertical axis of the housing with the formation of one cylindrical block and two annular, in addition, the inner cylinder is installed with a gap between its lower end and the bottom of the housing, and the outer cylinder with a gap between its upper end and the roof body shkoy.

A known filter for water purification [JP 2005288438, 2005], providing the removal of water from nitrate and sulfate ions. The water in the cartridge first passes through a layer of ion exchange resin having calcium ions as an exchange cation, and then water passes through a layer of anion exchange resin.

Known cartridge filter element [RU 60874 U1, 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 is made in the form of a “sandwich”, the lower and upper layers of which are synthetic non-woven materials that freely pass water, between which there is an inner layer of sorption material based on fibrous sheet material of organic or inorganic origin, modified with nanosized particles of aluminum oxide hydrate, designed for fine water purification and water purification from microorganisms. The inner layer is made in the form of a smooth tape formed from many layers of sorption material; the second variant 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. The inner layer is made in the form of a corrugated tape formed from many layers of sorption material.

CARTRIDGE FOR CLEANING A LIQUID (OPTIONS) is known from the prior art (patent RU 83941 U, B01D 27/00, C02F 1/00, Published: 06/27/2009). The utility model relates to devices for purifying liquids by filtration using sorption and ion exchange processes, in particular, to produce drinking water and can be used in process water treatment systems for various industries, for domestic use, pharmaceutical purposes, as well as in the field. The objective of the proposed technical solution is to develop a replaceable cartridge with a high degree of purification of the liquid from harmful impurities. Effect: expanding the scope of the proposed cartridge due to the fact that it combines the stages of mechanical, microbiological treatment and cleaning of inorganic and organic contaminants. According to the first and second embodiments, the task and the technical result are achieved in that the liquid cleaning cartridge contains a perforated skeleton and a sorption-filtering material formed around it, including at least two layers of protective material and a multilayer sorption material placed between them, a plurality of layers which is provided with winding in the form of a roll of at least one layer of web or tape around the perforated frame, connected by end parts. According to the third and fourth embodiments, the task and the technical result are also achieved by the fact that the liquid cleaning cartridge contains a perforated skeleton and a sorption-filtering material formed around it, including at least two layers of protective material and a multilayer sorption material placed between them, multiplicity layers of which is provided by winding in the form of a roll of at least one layer of a corrugated sheet or tape around a perforated frame, connected by end parts . A distinctive feature of the proposed cartridge according to the first and third embodiments is that it additionally contains a cup mounted inside and on the same axis with a perforated frame, as well as a charge of ion-exchange resin placed inside the cup. A distinctive feature of the proposed cartridge according to the second and fourth embodiments is that it additionally contains a cup mounted inside and on the same axis with a perforated frame, a charge of ion-exchange resin placed in the space between the perforated frame and the glass, as well as a load of activated carbon, placed inside the glass.

All solutions known from the prior art have generally elongated cylindrical, conical or parallelepipedal forms of cartridges with sorbent material.

The disadvantage of such forms is that with the same volume of the charge (cartridge), the largest surface of the sorbent layer will be on the filter of spherical shape, which means that the resource of such a filter will be greater than that of others. However, such forms of cartridges are not known in the art.

Known water purification systems in the form of filter jugs of the type "Barrier" [1] and "Aquaphor" [2]. These systems contain a jug capacity for clean water, onto which a stacked capacity for raw water is installed, into which a filter cartridge is inserted.

Their disadvantage is that the cartridges of the cleaning systems are constantly in the water, the water in the tank is constantly stagnant, as a result of which the water blooms and rots. The process of installing a new cartridge also does not provide hygiene, as the user twists it with his hands, then the same cartridge is constantly in a container of water. A water tank is always in the kitchen and takes up space, even when not needed.

The closest solution is the patent RU 11925411 (publ. 08/20/2012) for a device for water purification, containing a cartridge, inside which there is a sorbent substance, an inlet for supplying water from the outside of the cartridge, an outlet for withdrawing from the center of the cartridge, characterized in that the cartridge is made spherical or elliptical, close to the spherical shape.

The technical result of the claimed device is to increase the service life and improve sorption in comparison with other devices having the same filter volume, as well as increasing the hygiene of the filtration system, there is no need to constantly keep the filter cartridge in water, and containers with water.

The specified technical result is achieved due to the fact that the water purification device containing a container for clean water, a tank for untreated water, configured to fix a filter cartridge on it, inside which there is a sorbent substance, moreover, the cartridge has an inlet for supplying water ( on the outside of the cartridge), an outlet for output (from the center of the cartridge), characterized in that the cartridge is made spherical or elliptical in shape, and the tank for raw water is connected to the filter cartridge through the fitting, and the filter cartridge contains a removable support platform with legs or rests on the support part of the tank for purified water.

The composition of the material of the filter cartridge includes PET and / or PVC, and / or polyethylene. The holes of the filter cartridge can be closed with mesh membranes, the function of which is to prevent the sorbent from falling out of the cartridge. Mesh membranes can be made removable. The filter cartridge contains a sorbent substance that has the function of freely falling asleep in the inlet for supplying water and getting enough sleep from the outlet for outlet. The inlet for water supply and the outlet for the output of the filter cartridge are sealed with water supply and outlet pipes, respectively.

In addition, the tank for untreated water is made with the possibility of connection with the filter cartridge through a fitting fixed to the inlet for supplying water to the filter cartridge. The tank for untreated water at the point of docking with the filter cartridge contains an elastic gasket. In front of the fitting on the filter cartridge can be placed a support platform, made in the form of the bottom of the tank for untreated water. The filter cartridge contains a removable support platform on the legs, made with the ability to dock with a pipe for water outlet. The container for purified water contains a thrust pad in the area of the side walls, the function of which is to hold the legs of the removable supporting platform of the filter cartridge.

The utility model is illustrated by drawings.

In FIG. 1 shows the constructive device of the filter cartridge in operation, where 1 is the cartridge housing, 2 is the inlet pipe, 3 is the outlet pipe, 4 is a mesh membrane.

In FIG. 2 shows a structural device for water purification with removed pipes.

In FIG. 3 shows the design of the filter cartridge during the cleaning of the sorbent, where 5 is the inlet of the cartridge, 6 is the used sorbent, 7 is the outlet of the cartridge.

In FIG. 4 shows the design of the filter cartridge during filling with a new sorbent, where 8 is a new sorbent.

In FIG. 5 shows a first example of a design of a treatment device according to a utility model (in a packaged non-working (traveling) condition), where 9 is a container for purified water, 10 is a removable support platform with legs, 11 is an elastic pad, 12 is a support platform, 13 is nipple, 14 - tank for untreated water.

In FIG. 6 shows a first example of a design of a treatment device according to a utility model (in working condition), where 15 is a thrust pad.

In FIG. 7 shows a second example of a design of a treatment device according to a utility model (in a packaged non-operational (traveling) condition).

In FIG. 8 shows a second example of a design of a treatment device according to a utility model (in working condition).

A utility model can be performed as follows.

We show the device of the filter cartridge 1, inside of which there is a sorbent substance 6. The filter cartridge 1 contains an inlet 5 for supplying water, an opening for the outlet 7 of purified water.

The novelty of the device is the implementation of the filter cartridge 1 of a spherical or elliptical shape. If the cartridge is made by sintering with a composite material, then this is done in order to use the cartridge as a disposable device for water purification. This manufacturing process simplifies and reduces the cost of the cartridge. In this case, the composition of the cartridge material may include PET and / or PVC, and / or polyethylene.

The inlet 5 and outlet 7 holes of the filter cartridge 1, or only the outlet 7 of the cartridge cartridge can be closed with mesh membranes 4, the function of which is to prevent the sorbent 6 from falling out of the filter cartridge.

The mesh membranes 4 must be removable if the filter cartridge 1 is used as a reusable device. To perform the reusable function, the filter cartridge 1 must contain a sorbent substance 6, 8, which has the function of freely falling asleep in the water inlet and pouring out of the outlet.

The process of precipitation of the used sorbent 6 is shown in FIG. 3. Why remove at least the lower membrane 4, or also the upper one, through which the used sorbent is then poured 6. To improve and speed up the process of cleaning the cavity of the filter cartridge 1 from the used sorbent 6, water can be supplied through the inlet pressure (i.e. rinse the cartridge cavity from the sorbent).

Then the filter cartridge purified from the sorbent is again filled with a new clean sorbent 8 (see Fig. 4) through the inlet 5, and the outlet 7 is closed with the membrane 4.

The water inlet 5 and the outlet 7 should preferably be sealed to the water supply 2 and water outlet 3, respectively, so that the filter cartridge can be quickly and efficiently replaced or cleaned.

The principle of the cleaning device according to the utility model as a whole is as follows: the containers for untreated 14 and purified 9 water are placed relative to each other in the working position so that the filter cartridge 1 is located entirely above the water level in the purified water tank 9. The fitting 13 in the tank for raw water 14 is connected to the filter cartridge 1 in the area of the inlet for supplying water to the filter cartridge. The fitting 13 acts as a docking station. The raw water tank 14 at the interface with the filter cartridge 1 may contain an elastic gasket 11, the purpose of which is a more tight connection in the area of the nozzle 13 of the container 14 and the filter cartridge 1. In front of the nozzle 13, a support platform 12 can be placed on the filter cartridge 1 made in the form of the bottom of the tank 14 for untreated water. The purpose of the platform 12 is to increase the reference area of the tank 14, in order to exclude its reeling.

The filter cartridge 1 may include a removable support platform 10 on the legs, configured to dock with the pipe 3 for water outlet. While the tank for purified water 9 may contain a thrust pad in the area of the side walls, the function of which is to hold the legs of the removable supporting platform 10 of the filter cartridge 1.

The principle of operation of the cleaning device is as follows: in the marching (not working) state (see Fig. 5, Fig. 7), the tank 14 for untreated water serves as a sealed cover located on top of the tank 9 for purified water. Inside between them, in the working position, the filter cartridge 1 is fixed. In the traveling (not working) state (see Fig. 5, Fig. 7), the utility model ensures that there is no need to constantly keep the filter cartridge in water, and containers with water. In the working position, the tank 14 for untreated water is turned over and fixed on the filter cartridge 1 bowl down. If a removable support platform 10 is fixed to the filter cartridge 1 on the legs, then it is also unscrewed or unfastened and then again fixed on the pipe 3 to withdraw water with the legs down.

If the tank for purified water 9 contains a thrust pad 15 in the area of the side walls, then the legs of the removable supporting platform 10 of the filter cartridge 1 abut it (Fig. 6). In the absence of such a removable supporting platform 10, the filter cartridge 1 simply rests on the supporting part of the purified water tank 9, which is performed with a tapered truncated end (Fig. 8).

The absence of the need to constantly keep the filter cartridge in the water eliminates the contact of the filter cartridge 1 with water and improves the hygiene of the filtration system,

Due to the special shape of the cartridge, the service life and sorption are improved compared to other devices having the same filter volume, since with the same volume of the charge (cartridge), the largest surface of the sorbing layer will be a spherical filter, which means that the resource of such a filter will be longer, than others.

But placing a ball filter in a traditional filter jug [1, 2] is not rational, since stagnation of water will not contribute to an improvement in sorption compared to other devices having the same filter volume.

Placing the containers for untreated and purified water in relation to each other in the working position so that the filter cartridge is located entirely above the water level in the tank for purified water, allows the device to transform into a compact traveling state without water and increases the service life of the filter cartridge , contributes to the improvement of its sorption already due to its spherical or ellipsoidal shape.
