Description

FIELD OF THE INVENTION

The invention is intended for household purification of drinking water, by filtering, and more specifically to methods of sorption and bactericidal purification of liquids using filters and purification devices, which provide the ability to filter liquid through adsorption-bactericidal material in domestic conditions, providing improved sorption and bactericidal purification and improvement quality of the purified liquid.

The invention may find application for the purification of drinking water and other household liquids in the chemical, medical and other industries.

State of the art

The need for drinking water treatment in domestic conditions, in particular in the final water treatment systems, is growing due to increasing pollution of natural water, population growth and increasing demands on the quality of water consumed. With the increasing amount of medical and environmental information that water pollution causes disease, the need to use purified drinking water becomes apparent.

Water filtration devices are widely used, consisting of three replaceable purification modules providing a three-stage water filtration. A conventional filter for water purification of this type consists of a block of collectors and three glasses attached to it on the thread, in the cavities of which filter elements are located. The collector block consists of three separate collectors interconnected by adapters. An example of such a separate collector assembly with a cup attached to it in which a filter element is mounted is described, for example, in US Pat. No. 3,859,216. The inlet and outlet openings of the collector body in this design are threaded for connection with other similar units. Thus, the tightness of the filter is ensured by six sealed joints. At the same time, the composite structure does not provide sufficient reliability of these connections, since leaks are possible in the places of these joints with time. The presence of three separate housing parts of the collectors complicates the design of the housing of the device, and, in addition, in the production it is necessary to produce three housing parts of the collectors equipped with threads.

Known filter device described in US patent 4,786,420 and 5,180,491. The devices according to these patents contain three glasses with filter elements installed in them. The collector block consists of three collectors interconnected by means of a threaded connection. This known composite design of the collector housing has the above disadvantages, and also has insufficient rigidity. In addition, in order to permanently fix such a filtering device for its subsequent use in domestic conditions, an additional element of the bracket type is required, by means of which the filtering device is attached to a wall or something similar and which provides additional rigidity to the filter construction.

As the closest analogue, the Aquafor Trio water purifier manufactured by LLC Akvafor since 2004 was selected in accordance with TU 3697-042-11139511-2004. It has all of the above disadvantages inherent in the prior art water purifiers of this kind.

Therefore, the objective of the present invention is to simplify the design and improve the manufacturability of the manufacture of the hull of the filtering device while ensuring rigidity and reliability of its design.

Disclosure of invention

To solve this problem, a device is proposed for purifying a liquid, in particular water, containing a collector, at the ends of the housing of which there are inlet and outlet pipes, three glasses with filter elements connected to the collector body via a detachable connection and communicating with the collector channel, while the collector is equipped with a partition that prevents the passage of fluid flow directly through the channel of the collector. The device is characterized in that the collector housing is made in the form of a single part, with each of the inlet and outlet pipes having an end wall that prevents the said pipes from communicating directly with the collector channel, and at least one hole in the side surface communicating with one of extreme glasses. Between the outer surface of each of said inlet and outlet nozzles and the inner surface of the wall of the manifold body, there is preferably an annular gap, wherein said at least one opening communicates with the cup through said annular gap. To seal the connection of the nozzles with the housing, each of the mentioned inlet and outlet nozzles is equipped with sealing elements. In a preferred embodiment, the glasses with filter elements are provided with an external thread, through which they are connected to the corresponding threaded sockets of the manifold body. The collector housing may have means for hingedly mounting the device on a support made together with it. Moreover, in the particular case, this tool can be made in the form of jumpers between the sockets of the collector body, equipped with holes. In one embodiment, the manifold body has grooves in the place of installation of the inlet and outlet pipes, and each of said inlet and outlet pipes is provided with corresponding protrusions, said grooves and protrusions having elements forming a snap connection of the “latch” type.

Thus, due to the design of the collector body in the form of a single part and the design of the inlet and outlet nozzles having end walls that replace the corresponding partitions in the collector channel, usually performed in known structures, a simplified design of a device for cleaning liquid has been created.

At the same time, the collector case of this device is more technologically advanced in manufacture due to the fact that it can be manufactured by casting one part. In addition, in comparison with the known structures, a more reliable device is created, because due to the fact that the collector body is one part, and not three parts interconnected, the possibility of leaks in the collector channel, which are possible with the composite structure of its body, is excluded, and there is no need to install additional seals at the joints of the composite housing. Also, due to a single housing, the proposed design is more rigid, which is important when fixing the device to a support.

The proposed device additionally allows to exclude from the structure of the structure such an element as a bracket, through which the device is attached to the support. Due to the unified design of the collector body, the elements for fixing the device to the support are made directly on the collector body, namely on the jumpers between the threaded sockets.

The implementation of the invention

A device for purifying a liquid according to the invention is shown in FIG. The device comprises a collector 1, in the housing 2 of which the inlet and outlet pipes 3, 4, respectively, are installed from the ends. The collector housing 2 has three threaded sockets 5, 6, 7, into which three glasses 8, 9, 10 are screwed, in the cavities 11, 12, 13 of which there are filter elements 14 having an internal cavity 15 (in FIG. 1, filter elements in glasses 9 and 10 are not shown). Each of the glasses 8-10 is equipped with an annular protrusion 16, on which the filtering elements 14 are supported to prevent direct flow of water from the gap between the wall of the glass 8-10 and the outer surface of the filtering element 14 into the internal cavity 15. A partition 18 is installed in the collector channel 17, preventing the passage of water directly through the channel 17 of the collector from the first downstream glass 8 to the third downstream glass 10, bypassing the middle glass 9. Between the outer side surface of the nozzles 3, 4 and the inner surface of the wall of the housing 2 of the collector there is an annular gap forming a cavity 19.

In more detail, the design of the inlet (outlet) pipe 3 (4) is shown in FIG. 2, which in general can have an identical design in order to unify the parts of the device. The inlet (outlet) pipe 3 (4) has an end wall 20, which prevents the passage of water directly through the channel 17 of the collector, bypassing the first downstream glass 8 (for inlet pipe 3) and bypassing the third downstream glass 10 (for exhaust pipe 4). The pipe 3 (4) has annular protrusions 21 and 22, which, when installed in the collector body 2 together with a recess in the body 2, form the aforementioned cavity 19. In the lateral surface of the pipe 3 (4), through holes 23 are formed between the annular protrusions 21, 22 together with channel 24 of the pipe, a kind of additional collector. The holes 23 communicate with the first and third downstream glasses 8 and 10.

Figure 3 shows in more detail the elements of the pipe, which serve to secure it in the housing 2 of the collector. The nozzles 3, 4 are fixed in the collector case 2 by means of a “latch” type lock connection, due to the presence of a protrusion 25 with a groove 26. In the case 2 there are mating parts from both ends, representing the corresponding grooves 27 with ridges 28, which together with grooves 26 on the protrusions 25 of the pipes 3, 4 element of the latch.

The holes 23 communicate with the first and third downstream glasses 8 and 10 through the inlet 29, 30 and exhaust 31, 32 holes, which are equipped with glasses 8, 10, respectively (see figure 1).

Each of the nozzles 3, 4 installed in the housing 2 of the collector is equipped with sealing elements 33 (see Figure 2). In the end openings of the nozzles 3, 4, standard elements 34 for fastening the tubes for connecting to an external water supply are inserted.

Figure 4 presents a rear view of the device, which shows the means for hinged mounting the device on a support, namely for attaching to a wall or something like that. The tool for hinged mounting is a hole 35 made on the jumpers 36 between the threaded sockets of the collector body 5, 6, 7, into which the glasses 8, 9, 10 with filter elements are screwed. Using these holes 35, the filter device is attached to the wall with screws.

The device for water purification shown in Fig.1-4, operates as follows. Water from the water supply enters the device through the inlet pipe 3, passes through the openings 23 of the inlet pipe into the cavity 19 formed between the inlet pipe 3 and the collector body 2. Through the hole 29, water fills the cavity 11 between the outer surface of the filter element 14 and the housing of the cup 8. Then, the water enters the volume of the filter element 14 over its entire external area and is cleaned, and exits along the entire inner surface of the filter element into its internal cavity 15. Next through the opening 31 and the collector channel 17, water enters the cavity 12 of the glass 9, in which the filter element 14 of the 2nd stage is installed, in which the filtering is similarly carried out. After the water leaves the filter element of the 2nd stage, a similar filtering process is repeated in the filter element of the 3rd stage. And finally, upon completion of the filtration of water in the filter element of the 3rd stage, the purified water from the outlet 32 of the cup 10 through the holes 23 of the outlet pipe 4 enters the tap of clean water.

Thus, due to the design of the collector body in the form of a single part and the above-described design of the inlet and outlet pipes, a simplified design of the liquid purification device has been created, the body part of which is more technologically advanced to manufacture and has greater structural rigidity compared to known structures.

In addition, the proposed device is more reliable in operation, since the possibility of leaks in the collector channel, which are possible with the composite structure of its housing, is excluded.

The design of the collector body in the form of an integral part also allows elements to be mounted on the support directly on the collector body, namely, on the jumpers between the threaded sockets.
