Description

The device relates to the field of production of liquid purification equipment, mainly drinking water, intended for use as stand-alone devices in field conditions, in summer cottages and garden areas, by army units in the field, in the event of extreme and emergency situations.

Known water purification devices with gravity feed. An example of such devices is decanters / jugs and large containers, where the treated water is poured, for example, from an open reservoir. The principle of operation of such devices: the liquid is poured into the receiving tank, under the influence of gravity, it passes through the filter module and enters the receiving tank for purified water. Such water purifiers are widely represented, for example, by Akvafor LLC (www.aquaphor.ru).

A disadvantage of the known devices with gravity feed is a gradual decrease in the filtration rate, up to the cessation of this process, since the pressure of a relatively low column of liquid above the filter module is not enough to overcome the hydraulic resistance of the filter materials.

This is most affected by the purification of water extracted from reservoirs, where on the surface there may be films of oil products, as well as particles of large debris or inorganic and organic suspensions. In addition, carafes / jugs have a hard, often fragile body of a sufficiently large size and, as a result, are not suitable for traveling and field conditions.

In the prior art, the problem of overcoming the hydraulic resistance of the filter material is solved by the creation of autonomous pressure head devices for liquid purification. In such devices, the liquid passes through the filter forcibly due to the difference in air pressure between the receiving tank for untreated liquid and the receiving tank for purified liquid, for example, due to the manually controlled air pump (pump) integrated in the device [US Patent No. 7413653 (James Dennis Powell (US), published August 19, 2008, BO1D 29/56, CO2F 1/00). US patent No. 7507338 (Filtrex Holding pte ltd (GS), publ. 24.03. 2009, CO2F 1/28, 1/44, 1/50)].

The disadvantage of these known devices is the need to filter film and mechanical inclusions that fall into the tank for untreated water when filling it from an open reservoir, the rigidity of the structure, its dimensions and additional weight due to the built-in pump, which creates inconvenience when transferring the device, for example, in a backpack. An additional mechanical device (pump) as a whole reduces the reliability of the device as a whole.

In the prior art, devices are known whereby water is taken for cleaning from a certain depth of an open reservoir, which immediately eliminates the need for filtering surface films and floating debris. This, for example, is a device in the form of a short (up to 20 cm) rather light tube with filtering materials placed in it. An intake hole was made from one end of the tube, immersed below the water level in the reservoir, and a nipple was made at the other end, which can be taken into the mouth and drawn in purified water (Press Service of Tomsk Polytechnic University, http: / news.tpu.ru / news / 2017 / 04/04/27025).

A disadvantage of the known device is its individual affiliation. The use of the device allows drinking the purified water from an open reservoir only to the owner of this device. Such a device is not suitable for filling any container with purified water. A disadvantage of the device is the need to drink in a prone position, which is inconvenient and, of course, difficult if the approach to the water mirror is difficult.

Closest to the claimed is the well-known Swiss device company "KATADYN" water purification mainly from open reservoirs, which includes an intake hose connected to the housing, which houses the filter module. The casing is equipped with a pump and an outlet for purified water. At the same time, the outlet has a screw thread for attaching a container with a threaded neck (for example, a standard plastic bottle) for receiving clean water (https://go.mail.ru/search?g = Filter + Pocket + Katadyn) - a prototype.

The device operates as follows. The intake hose is immersed in a pond to a certain depth. The lever of the pump pumps raw water through a housing with a filter module. Purified water enters the tank connected to the outlet of the housing for collecting purified water.

The disadvantages of the prototype are:

The prototype has two mandatory elements: the first is a rigid case with a filter module and a pump, and the second is a receiving tank. The presence of two necessary elements increases the overall dimensions of the device.

The body of the device and the receiving capacity of the prototype are made rigid, which complicates their transportation in the outer pockets of the backpack, the use of the device requires unpacking / packing the backpack.

The prototype device operates on the principle of absorption of water from a reservoir due to the operation of the pump and is not adapted, if necessary, to filter water using the gravity feed method.

The prototype has a high cost. According to price lists posted on the Internet, the cost of the KATADYN device ranges from 20 to 25 thousand rubles.

The device can only be used for its intended purpose and its case cannot serve as a container for storing water or, for example, picking berries, mushrooms, which is convenient in field conditions.

The technical task of the invention is to simplify the design of the device, expand its technological and operational capabilities, reduce weight and dimensions, reduce its cost.

This object is achieved in that in a water purification device in traveling conditions, including a housing and a filter module, the housing is open at the top, has a rigid upper edge and bottom, and side walls made of non-rigid waterproof material, a handle is fixed on the rigid edge of the housing in the form of a symmetrical, relatively the axis of rotation, of a rigid contour, for example, of a rectangular one, which can be rotated inside the casing with the vertical contour of its tangent contact with the bottom of the casing, and laterally the casing wall is hermetically mounted a culvert in the form of a sleeve, for example, a threaded one, which is hermetically fastened to the filter module on one side and with a sealed plug on the other side, while the intake opening of the filter module is always located on the side of the water entering the treatment. The side walls of the housing can be equipped with several culvert elements installed in their lower part, hermetically sealed with filter modules on the one hand and airtight plugs on the other hand, while the intake opening of the filter modules is always located on the side of the water entering the treatment. The handle, in the form of a rigid contour, can be made round, oval or polygonal. The bottom of the housing can be equipped with a latch for the vertical position of the rigid contour of the handle. The device may be provided with clips, for example, in the form of brackets, to hold the side walls of the housing in a compressed (traveling) position.

The device has the following differences from the prototype:

- the case is open at the top, has a rigid upper edge and bottom, side walls made of non-rigid waterproof material;

- a handle is fixed on the rigid edge of the casing in the form of a symmetrical, with respect to the axis of rotation, rigid contour, for example, a rectangular one, which can be rotated inside the casing while ensuring the contour of its tangent contact with the bottom of the casing in the vertical position;

- in the lower part of the side wall of the housing a culvert is installed hermetically in the form of a sleeve, for example, a threaded one, which is hermetically fastened to the filter module on one side and with a sealed plug on the other side, while the intake opening of the filter module is always located on the side of the water entering ;

- the side walls of the housing can be equipped with several culvert elements installed in their lower part, hermetically sealed with filter modules on the one hand and airtight plugs on the other hand, while the intake opening of the filter modules is always located on the side of the water entering the treatment;

- the handle, in the form of a rigid contour, can be made round, oval or polygonal;

- the bottom of the body can be equipped with a latch for the vertical position of the rigid contour of the handle;

- the device can be equipped with clips, for example, in the form of brackets, to hold the side walls of the housing in a compressed (traveling) position.

This will simplify the design of the device, expand its technological and operational capabilities, reduce weight and dimensions, reduce its cost.

A comparative analysis of the claimed device and prototype reveals the presence of distinctive features of the claimed device in comparison with the closest analogue, which allows us to conclude that the proposed technical solution meets the criterion of "novelty."

In the patent information fund that we reviewed, no technical solutions with the indicated differences were found, as well as technical solutions with the specified set of distinctive features.

The proposed technical solution is applicable and will be used to create water purification devices in camp conditions.

The invention is illustrated by drawings, which depict:

In FIG. 1 is a schematic diagram of a device, cross section, front view.

In FIG. 2 - section AA - in FIG. one.

In FIG. 3 is a section BB in FIG. one.

In FIG. 4 - device in the stowed (assembled) position.

In FIG. 5 - device in position for filtration with gravity feed.

The device (Fig. 1) includes a top-open case with a rigid upper edge 1, a rigid bottom 2 and side walls 3 made of non-rigid waterproof material (for example, tarpaulin, polyethylene, rubberized fabric), a handle 4 in the form of a symmetrical axis of rotation 5 ( Fig. 2) a rigid circuit, a hermetically sealed culvert in the form of, for example, a threaded sleeve 6 (Fig. 3) located in the lower part of the side wall 3 and hermetically fastened to the filter module 7, the intake opening of which is located on the side they are supplied to the water purification 8, and the plug 9. The device may include a latch 10 (Fig. 1) for the handle 4 and staples 11 (Fig. 4).

The device operates as follows.

Removing the clamps 11 (if they are included in the device), turn the horizontally located handle 4 and set it in a vertical position. When turning the handle 4, the part or point of the rigid contour of the handle 4, which is farthest from the axis of rotation 5, slides along the hard bottom 2 of the housing and spreads, stretches the non-rigid side walls 3 between the hard upper edge 1 and the bottom 2 of the device body. Thus, as a result of the rotation of the handle 4, the housing takes the form of a container open from above, that is, its shape in the operating position. The vertical position of the handle 4 can be held by the latch 10 in the form, for example, of two parallel rods rigidly fastened to the rigid bottom 2 of the formed container.

After removing the plug 9 from the casing element in the form of a sleeve 6, the container is immersed in the purified water 8 to the lower boundary of the rigid upper edge 1 by pressing on the upper part of the rigid contour of the handle 4. Then, due to the pressure difference outside and inside the container, through the filter module 7 the tank receives purified water (in Fig. 1 and Fig. 2 conventionally not shown). With sufficient filling with purified water, the housing for the upper part of the handle 4 circuit is removed from the water to be purified and the plug 9 is installed on the sleeve 6. As a result of the operation of the device, purified water is obtained, the volume of which depends on the volume of the device body.

To bring the device into the stowed position, the handle 4 is installed horizontally, the case is compressed by a vertical force, deforming the non-rigid side walls, and fixed in this position, for example, with clamps 11 (Fig. 4).

Additionally, the device can be used in the case of water purification by gravity feed. Then the device operates as follows (Fig. 5).

The device is put into operation by the sequence of steps described above. Then, the filter module 7 and the plug 9 are removed from the sleeve 6 of the culvert element. The filter module 7 is mounted on the sleeve 6 of the culvert element so that the intake opening of the filter module is directed into the device’s tank. Pour, using a mug, a jar, through the case open from above, untreated water 8, which due to gravity flows through the filter module 7 of the culvert. Purified water can be collected in any additional container (not shown conditionally in FIG. 5).

The gravity feed method can be used in case of insufficient depth of the reservoir with untreated water (for example, a reservoir in the form of a puddle), when it is impossible to immerse the device casing to a level that provides a sufficient pressure drop outside and inside the device casing. Thus, the claimed device allows you to purify water extracted from both deep and shallow reservoirs.

The performance of the device can be improved by providing it with several culvert elements with filtering modules 7, simultaneously acting in the implementation of the water treatment process. At the same time, the filter module can be replaceable and designed to filter 20-50 liters of water, which in most cases is satisfactory for traveling conditions. Then the filter module will be small, light and cheap, in contrast to the filter modules of the prototype, the cost of which currently exceeds 15 thousand rubles.

The ability to make the handle of the device in the form of a round, oval or polygonal shape allows you to choose the optimal shape of the case for specific traveling conditions.

The inventive device can be used as a traveling tank. It can store water for household needs, use as containers for picking mushrooms or berries. The device, assembled in a stowed position, is portable. The device is very simple and convenient for transportation and operation.
