Description

 The invention relates to devices for the purification of drinking water from a centralized water supply or from an underground source, mainly in domestic conditions, when it is required to have a supply of purified water, for example, due to frequent interruptions in the supply of water from a water supply system.

 A device of a traditional construction is known, used for cleaning short-term storage of water in everyday life, consisting of a container made in the form of a jug, a funnel mounted on it with an attached sleeve filled with filter material and / or sorbent, closed on top with a slit filter element [1].

 Due to the design of the water tank in the form of a jug, water purifiers of a similar design have a limited volume of a portion of purified water (usually 1.5-2 l) and an insufficient resource for regular use for more than 1 month, since the load is placed in a compact and limited housing filtering area of a replaceable cartridge.

 A small-sized non-pressure filter for water purification is known, containing a container with a funnel and a neck, filter material loaded into the container, and a device for draining purified water. Moreover, the container is made in the form of a rectangular shelf of hollow panels interconnected by a spike connection; horizontal panels have partitions to create a tortuous course of purified water [2].

 The disadvantages of this filter are the presence of mechanical connections between the elements of the tank, which require sealing; high material consumption and dimensions of the structure due to its implementation from hollow panels. The low cross-section of the water passages and the accumulation of air in the charge increase the hydraulic resistance to the flow of water, and as a result, the filter life is reduced. This design also does not allow conveniently loading and unloading filter material. The design of the filter does not allow using it as a portable water purifier.

 A known device for water purification, selected as a prototype, containing a device for supplying the source water, a cylindrical tank with a conical bottom, in which there is a drain connected to a device for draining the purified water, and granular carbonate mineral loaded into the tank as a sorbent. The source water supply device consists of a pressure pipe and an adjustable valve associated with a water level regulator in the device. Inside the tank there is an airlift with a layer of granular carbonate mineral located in its upper part of the perforated plate. A device for draining purified water consists of a pipeline and a filter with activated silver-plated carbon [3].

 The disadvantages of this device for water purification are the low filtering surface of the drainage and the presence of an additional filter in the composition of the device for draining purified water, which increases the time for draining the purified water to unacceptable values; when performing drainage with large pores, and the filter with coarse activated carbon, the quality of water treatment decreases and removal of fine fractions of the filter material from the tank can be observed. For reliable disinfection of water, especially during long-term storage of purified water, the specified technical solution is ineffective. In addition, this device has large dimensions, which makes it difficult to use it as a portable water purifier.

 The objective of the invention is the creation of a portable free-flow water purifier with an increased resource by increasing the drainage surface; at the same time, the water purifier should be convenient in operation and provide in one tank water purification and the possibility of long-term storage of purified water without secondary pollution.

 The problem is solved due to the fact that in a known water purifier containing a container with a recess in the bottom, in which a drain is connected, connected to a device for draining purified water, the filter material loaded in the container, according to the invention, the recess in the bottom is made in the form of a horizontal elongated recess , the drainage is made of interconnected tubular elements with a length corresponding to the length of the recess and placed in the recess, and the tank is made with a neck and provided with a lid. The tank has at least two recesses in which the drainage is located, and in the horizontal section it is made predominantly rectangular, and the filter material placed above the bottom level is partitioned by at least one honeycomb grid placed horizontally, folding in the plane of the grid and consisting of two groups of mutually parallel thin-walled plates with slots for mutual connection, moreover, the shape and dimensions of the plates allow you to place the lattice in the folded state through the neck in a container and deploy there.

 It is advisable to install a pre-filter in the neck of a container made of circular cross section having a cylindrical body and a lower removable part made in the form of a cone with its top up, on which a fibrous filter material is placed.

 A bactericidal component is placed in the container, for example, as part of a filter material.

 The implementation of the recesses elongated in the horizontal direction and predominantly wedge-shaped along which the tubular drainage is placed, as well as the implementation of the recesses and the placement of tubular elements the entire length along the long side of the tank, allows to increase the drainage surface by about 2 orders of magnitude compared to the known water purifier, use a water purifier without a pressure source source water and without compromising the quality of purified water at a convenient drain time and increase the resource. The increase in the number of recesses in the bottom of the tank allows you to increase the useful volume of the tank without increasing its height, as well as to increase the drainage surface by a multiple of times.

 The implementation of the container in the cross section is predominantly rectangular and the sectioning of the filter material placed above the bottom of the filter with a honeycomb grid limits the movement of the filter material on its surface during transportation of the water purifier and the filling of purified water and thereby improves the quality of water treatment, loading resource, etc.

 The use of a preliminary filter with easily replaceable fiber loading, which also functions as a water jet divider and a limiter of its consumption, allows to increase the resource of the filtering material of the container and reduce erosion of its surface.

 The drawing shows the proposed water purifier - side view.

 The water purifier consists of a tank 1 with a continuous upper part, with a handle for carrying the water purifier 2, on which a bracket 3 is mounted for hanging the water purifier on the wall, with a neck 4 screwed onto it with a cover 5. Inside the tank 1 is loaded filter material 6, partitioned by a honeycomb grill 7 A pre-filter is placed in the neck 4, consisting of a housing 8 in the form of a cylinder with stops in the upper and lower parts and made in the form of a cone with the top upward of the removable part 9 placed in the housing 8 on which the fibers are placed filtering material 10. The stops are designed to prevent the pre-filter housing 8 from falling into the neck 4 and the removable cone 9 from the housing 8.

 In the bottom of the tank 1 there are two wedge-shaped recesses 11 with tubular drains 12 located therein, hydraulically connected by a tube 13 to each other and with a flexible transparent tube 14 for draining the purified water.

 The free end of the flexible transparent tube 14 is fixed in the lid of the container 5 with the possibility of free rotation of the latter: this eliminates the spontaneous release of the tube 14 during storage of water with subsequent undesirable emptying of the container 1, as well as to eliminate the loss of the cover 5.

 The device operates as follows.

 To fill the water to be cleaned, the cover 5 is turned off from the neck 4, the cover 5 is fixed on the upper surface of the tank 1, and the water to be purified through the neck 4 of the tank 1 and the pre-filter with fibrous filter material 10 is poured into the tank 1, where it is stored until use as in a layer of filter material 6 and above it. When pouring water, it is convenient to use a funnel (not shown), and the water level in the tank 1 to control a flexible transparent tube 14.

 To drain purified water, the cover 5 is turned out of the neck 4, the free end of the tube 14 is placed in a receiving container (not shown), and water is drained through the pipes 12 and 13 through the drains 12 for subsequent use, for example, for cooking.

 For ease of use, the water purifier can be hung in the kitchen on the wall, preferably near the sink, using the bracket 3 at a height of 120-140 cm from the floor level, which allows you to conveniently pour and drain water from the water purifier. Kitchen or other similar utensils can be placed on the top surface of the container.

 To ensure automatic filling of water into the tank, it can be equipped with a level control valve, which is connected to the water supply. The design of level control valves is well known to those skilled in the art and is widely used in the design of flush toilet tanks.

 If necessary, if the flow rate of the purified water through the pre-filter decreases, the filter load 10 of this filter should be replaced with a fresh one: the removable cone 9 of the preliminary filter is removed from the cylindrical body 8, the contaminated load of fibrous filter material 10 is removed, and a layer of fresh load 10 is placed on the cone 9 and the cone 9 with the load 10 is placed back into the cylindrical body 8, which is again installed in the neck 4.

 As necessary, when reducing the rate of discharge of purified water from the water purifier, the drains 12 can be purged with air, for example, using a bicycle pump. To do this, a tube from a bicycle pump is connected to the free end of tube 14, air is blown for 5-10 minutes, and if this is not enough to increase the rate of water flow, then load 6 of tank 1 is replaced. For this, a preliminary filter is removed from the neck, water is drained from capacity 1, capacity 1 is turned over and the load 6 of capacity 1 is removed; after that, the container 1 is turned back to its original position, fresh filter material 6 is loaded.

 The material of the load 6 is selected depending on the nature and degree of water pollution, as well as the requirements for purified water. To prevent microbiological contamination of water and water disinfection, bactericidal additives were introduced into the load 6, for example, a load of activated carbon impregnated with silver was used.

 The cone-shaped part of the pre-filter 9 is expedient to perforate or mesh to increase the resource of the pre-filter. As the fibrous filter material 10, medical cotton wool or the like can be used. materials approved for contact with drinking water.

 Depending on the contamination of the water, the loading volume 6 in the container 1 is 1-80%, preferably 5-40%, of the total volume of the container 1. The grain size of the granular filter material 6 is not less than 0.5-1.0 mm and not more than 3- 5 mm. The size of the holes (pores) in the drainage 12 should not exceed 0.1-0.2 mm. The inner diameter of the neck should be at least 50-60 mm.

 In the manufacture of a water purifier tank with a convenient handle made of light materials, mainly plastic, as well as with overall dimensions of 250x250x250 mm and a volume of about 10 l, the water purifier can be used as a portable one.

 Tests of this water purifier with a useful volume of 8 l showed that purified water can be completely drained in about 10 minutes, which suits most consumers. Moreover, when using activated carbon with a high content of fines, the removal of the latter from the load did not occur even at the initial time. During long interruptions in the operation of the water purifier, drying of the load did not occur, there was no extraneous smell and taste in the treated water.

 The advantages of the installation should also include the simplicity and convenience of filling the tank with water both in the presence of a centralized water supply system and in its absence; and if there is a water supply, the shape and connecting dimensions of the water fittings do not matter. It is also convenient to control the level of filling the tank and drain the purified water by the consumer.

 Thanks to the convenient placement of the filter material of the pre-filter, it is possible to quickly and easily replace this exchangeable material, and also increases the loading resource of the container. The absence of the need for a factory-made cartridge for replaceable loading, the possibility of using local filtering materials can simplify and reduce the cost of maintenance of the water purifier and increase its resource.

 Analysis of the proposed device shows that it meets the criterion of novelty, since in the known technical solutions not found a set of essential features identical to the above.

 The device meets the criterion of industrial applicability, as evidenced by an example of its implementation.

 The analysis of the proposed device also shows that the implementation of the tank is mainly rectangular in cross section, its bottom with elongated, mainly wedge-shaped recesses in which the tubular drainage is located, allows you to drain purified water for a user-friendly time, the combination of all the essential features allows not only to purify the water, but also to store it for a long time, to increase the convenience of operation and maintenance of the water purifier, which obviously should not be for a specialist from the prior art.

 Thus, the proposed technical solution meets the criteria necessary for its recognition by the invention.
