Description

The proposed portable device is designed to purify water from various pollutants (suspended particles, iron compounds, heavy metals, petroleum products, organic compounds, excess chlorine generated during water disinfection, etc.) and can be used to purify tap water in domestic conditions and in critical situations. , as well as for water purification from natural sources in field conditions.

A portable water purification device is known that contains a vessel for collecting purified water and storing filter elements inoperative, a housing mounted on the neck of the vessel and a filter cartridge located in the housing with a nozzle for accessing the purified water vessel (US, 5308482, class B01D 27 / 02, 1994). However, in this device to prevent the ingress of untreated water into the vessel, it must be directed past the neck of the vessel, which leads to incomplete use of the source water and creates inconvenience during operation.

A portable water treatment device is also known, which contains a container for purified water with a housing housed inside it, inside which there is a filter cartridge with an outlet pipe and an air outlet, fixedly mounted on the neck of a vessel for purified water (RU, 2113410, Cl. B01D 27 / 00, 1998).

This known device is a bulky design, because the filter element is located in the housing, placed in a container for purified water, and is fixed motionless. This significantly increases the weight of the device and makes it bulky, which is especially important, for example, in field conditions.

The closest in technical essence and the achieved result to the proposed technical solution is a portable device for water purification, containing a container for purified water, in the bottom of which a pipe is made for the removal of purified water, equipped with a filter element located inside it. ("Bulk bactericidal filter" Heracles-Do it yourself ", www. Gerakl-, 07.29.2008). As a container, this known device contains an inverted plastic bottle with a cut bottom, and as a filtering element, layers of hydrophobic cotton wool pressed against the bottle neck with openings, with a layer of graphene sorbent sprinkled between them. This known device is intended for use, for example, in areas of natural disasters. The consumer must make the filter element himself immediately before use from a kit containing a hydrophobic filter wool and a sealed bag with graphene sorbent. However, this device has a low service life (up to 30 l of untreated water for one set), productivity up to 0.5 l per minute.

The objective of the proposed technical solution is to simplify the process of preparation for operation, increase the resource of work and productivity.

The problem is solved in that in the proposed portable device for water purification, containing a container for purified water, in the bottom of which a pipe is made for the removal of purified water, equipped with a filter element located inside it, according to the proposed technical solution, the filter element is mounted on the pipe for the removal of purified water with the help of a fastening element and made in the form of a partially perforated tube, the perforated part of which has a coating made of at least three layers, of two layers filter cloth, between which is a layer of tissue sorption material, the end of the perforated part is muffled, while the end of the non-perforated part of the tube enters the collection zone of purified water.

The layer of tissue sorption material may additionally contain silver, which helps to improve the organoleptic properties of water and delays the development of pathogens in between use of the device.

It is desirable that the filter element was provided with a prefilter, which allows to increase the service life of the device. The prefilter can be made of filter material, metal mesh or other materials.

It is recommended that the perforated part of the tube be made of flexible material, while the fastening element is made in the form of a cork. This allows you to expand the range of containers used in the proposed device for purified water, and also allows you to tightly connect the filter element with a pipe for the removal of purified water.

It is desirable that the perforated part of the tube be made of flexible material and curved in the form of a spiral, which allows to reduce the volume of the filter element while increasing productivity.

It is also desirable that the tank for purified water was made in the form of a telescopic cup, which allows to reduce the size of the device when carrying it and to increase the volume of simultaneously purified water during its operation.

It is also recommended that the above, at least three-layer coating, be corrugated, which allows to increase the productivity and service life of the device.

In addition, in the case when the tank for purified water is made in the form of a closed volume, it is recommended that the perforation and coating on the tube of flexible material are located at a distance from the mounting element of the filter element on the nozzle for the removal of purified water equal to or greater than the height a nozzle for discharging purified water, and an aperture was made in the aforementioned fastening element for air access. This makes it possible to use standard products, such as bottles or flasks (including individual army flasks) as containers for purified water, to fill them with untreated water without removing the filter element, and speeds up the process of removing purified water.

Further, to illustrate the proposed technical solution, the schemes of its implementation are given, not limiting its scope.

Figure 1 shows a General view of the proposed device (the perforated part of the tube is made of flexible material).

Figure 2 shows a General view of the proposed device (coating the perforated part of the tube is corrugated).

Figure 3 shows a section of a filter element (the perforated part of the tube is made of flexible material and curved in the form of a spiral).

Figure 4 shows a vertical section of the filter element (the coating of the perforated part of the tube is corrugated).

Figure 5 shows a horizontal section of the filter element along the line aa (the coating of the perforated part of the tube is corrugated).

Figure 6 shows a section through a portion of a filter element with a pipe (the container for purified water is closed).

The proposed portable device contains a container 1 (Fig. 1, 2), a filter element 2 (Fig. 1, 2) located inside it (which can be equipped with a prefilter 3 (Fig. 1, 2, 3, 4, 5), fixed on the pipe for draining purified water 4 (Fig. 1, 2), made in the bottom of the tank 1 (Fig. 1, 2). The filter element 2 is made in the form of a partially perforated tube (perforated part 5 (Fig. 3, 4, 5) , non-perforated part 6 (Figs. 3, 4, 5)). At the end of the perforated part of the tube 5 (Figs. 3, 4, 5, 6) there is a plug 7 (Figs. 1, 2, 3, 4). The end of the non-perforated part tube 6 (figures 1, 2, 3, 4, 6) goes into the reception zone of purified water, and the perforated part of the tube 5 has a three-layer coating (layers of filter material 8 and 9 (Figs. 3, 4, 5, 6), between which there is a layer of tissue sorption material 10 (Figs. 3, 4, 5 , 6), which may contain silver, for air to enter the closed container, channel 11 (Fig. 6) is made in the fastener 12 (Fig. 3, 6) of the filter element 2 on the pipe for draining purified water 4.

The inventive portable device operates as follows.

Water from a natural source or water supply is poured into the tank 1. During the cleaning process, water passes through the prefilter 3 into the filter element 2, where it is purified from mechanical and dissolved impurities, and leaves through the pipe for purified water 4. Inside the filter element 2, the purified water passes sequentially through a layer of outer filter material 8, tissue sorption material 10 and a layer of inner filter material 9. If the layer of tissue sorption material 10 of the filter element 2 contains silver, then Odita simultaneous improvement of the organoleptic properties of water and delayed the growth of harmful microorganisms in the intervals between uses of the device.

The proposed device is simple to manufacture and operate, provides increased productivity (1.5-3 times) and a working life (2-4 times) compared to the analogue.

At the same time, the inventive device provides effective tertiary treatment of tap water in a domestic environment, as well as bringing epidemiologically safe natural waters to sanitary standards by organoleptic and chemical quality indicators (suspended solids, heavy metal compounds, oil products, organic compounds, residual chlorine content that appears in water during its disinfection with chlorine-containing reagents, etc.).
