RU193779U1 - BACTERICIDAL STORAGE TANK - Google Patents

Abstract

The utility model relates to reservoirs for supplying drinking water intended for long-term storage of water in a reservoir and simultaneous bactericidal treatment of this water with ultraviolet light during storage, as well as the distribution of treated drinking water for domestic or similar local water supply. The technical result consists in a relative increase in the intensity of ultraviolet water treatment in the area of the water outlet pipe with the constant possibility of visual monitoring of the state of the inner walls of the tank body (for plaque, sediment) without turning off the bactericidal lamp and without dismantling the housing cover. The technological operation of installing a bactericidal lamp and its replacement is also simplified, and it also creates the possibility of using an additional source of illumination of the internal cavity of the tank body without dismantling technological operations. The tank contains a housing 1, including a bottom 2 and a side wall 3 made of opaque material (stainless steel), as well as a cover 4, hermetically connected to the side wall 3 in its upper part. The cover 4 is made entirely of a sheet of monolithic polycarbonate, transmitting visible light, but protected from ultraviolet radiation. This protection is due to the presence on both surfaces of the polycarbonate sheet of protective coatings having the property of absorption (filtration) of ultraviolet radiation. The reservoir also contains nozzles for supplying and discharging water, spaced in height so that the nozzle for draining water is located in the region of the bottom 2. The reservoir also contains a protective pipe 5, which is located inside the housing 1 in the region of the bottom 2 and parallel to the bottom 2. The pipe 5 is one its end is hermetically fixed to the side wall 3 of the housing 1 with free access to the inner cavity of the pipe 5 from the outside of the side wall 3. The other end of the pipe 5 is muffled. The pipe 5 is made of light-transmitting material and is intended for placement in it of a bactericidal lamp of ultraviolet radiation. If necessary, visible light sources, for example, LEDs, can be additionally placed in the pipe 5 in order to more intensively illuminate the inner surface of the housing 1 with visible light. 6 s p. f-ly; 4 ill.

Description

The technical field to which the utility model relates.

The utility model relates to reservoirs for supplying drinking water intended for long-term storage of water in the reservoir and simultaneous bactericidal treatment of this water with ultraviolet light during storage, as well as the distribution of treated drinking water for domestic or similar local water supply.

State of the art

A known tank for ultraviolet disinfection of water, including a vertical cylindrical body with spaced apart nozzles for supplying and discharging water, as well as a protective tube (protective quartz cover, flask) for accommodating a bactericidal lamp of ultraviolet radiation, while the protective tube is installed coaxially inside the housing (vertically) and above the water discharge pipe (see the description of the invention to the USSR Copyright Certificate No. 1678769 A1, IPC C02F1 / 32, published September 23, 1991 Bull. No. 35).

The signs of a well-known reservoir, common with the features of the claimed technical solution, are the presence of a vertically oriented housing with spaced apart pipes and a protective tube designed to accommodate a bactericidal lamp of ultraviolet radiation.

The reason that prevents obtaining a technical result in a known tank, which is ensured by the claimed technical solution, is the coaxial location of the protective pipe, which makes it difficult for the tank to perform the functions of long-term storage of drinking water, simultaneous bactericidal treatment with ultraviolet light of drinking water during storage, and visual control of the internal condition body surface.

A known tank for bactericidal storage of water (prototype), made in the form of a vertically oriented body, including a bottom and side wall made of light-impervious material, as well as a lid hermetically connected to the side wall, the tank contains nozzles for supplying and discharging water, spaced in height so that the pipe for water drainage is located in the area of the bottom of the tank, as well as a protective tube installed inside the tank body, designed to accommodate bactericidal lamps in it ultraviolet radiation, so that this pipe is located in the region of the bottom of the tank parallel to this bottom and is hermetically mounted on the side wall of the tank with free access to the internal cavity of this pipe from the outside of this side wall (CN patent No. 203846559 U, publ. 24.09.2014) .

Signs of a known reservoir, common with the features of the claimed technical solution, are the above signs of a known reservoir.

The reason that prevents obtaining a technical result in a known tank, which is provided by the claimed technical solution, is that the main function of the protective pipe is the function of draining water from the tank, as a result of which this pipe is made of light-impervious material. Thus, in the known technical solution, the bactericidal treatment of water is carried out only in the volume of this pipe, i.e. the water that directly passes through this pipe in the process of its outflow from the tank. With this embodiment of the pipe, the bactericidal treatment of water located in the tank outside the pipe volume is not subjected to bactericidal treatment, which generally significantly reduces the effectiveness of the bactericidal storage of water in the tank. Moreover, in a known technical solution, the tank cap is made of the same material as the tank wall, i.e. from light-impervious material, and at the same time it (the cover) does not have a window for visual and UV-protected observation of the state of the inner wall of the tank during its use for its intended purpose.

The technical problem to which the technical solution claimed for patenting is directed is the need to ensure the possibility of long-term bactericidal storage of water in the tank while simplifying the operation of the tank and simplifying the monitoring of the state of the inner surface of the tank body. Utility Model Disclosure

The technical result, which mediates the solution of the indicated technical problem, is to ensure constant ultraviolet water treatment in the entire tank volume with a relative increase in the intensity of ultraviolet water treatment in the area of the water outlet pipe with the constant possibility of visual monitoring of the condition of the inner walls of the tank body (for plaque, sediment) without turning off the bactericidal lamp and without removing the housing cover. The technological operation of installing a bactericidal lamp and its replacement is also simplified, and it also creates the possibility of using an additional source of illumination of the internal cavity of the tank body without carrying out de-assembly technological operations.

The technical result is achieved by the fact that the tank for bactericidal storage of water is made in the form of a vertically oriented body, including a bottom and a side wall made of light-impervious material, as well as a lid hermetically connected to the side wall, while the tank contains nozzles for supplying and discharging water spaced in height so that the pipe for water drainage is located in the area of the bottom of the tank, as well as a protective pipe installed inside the tank body, designed to be placed in it a bactericidal lamp of ultraviolet radiation, so that this pipe is located in the region of the bottom of the tank parallel to this bottom and is hermetically fixed to the side wall of the tank with free access to the inner cavity of this pipe from the outside of this side wall, while the protective tube is made of light-transmitting material, and the lid of the tank body is made with the possibility of visual control protected from ultraviolet radiation through this cover of the state of the inner surface of the housing the cistern.

The technical result is also achieved by the fact that the specified cover is either made entirely of monolithic polycarbonate protected from ultraviolet radiation, or it is made of light-impervious material and contains a hole in which a sheet of monolithic polycarbonate protected from ultraviolet radiation is hermetically mounted.

The technical result is also achieved by the fact that the tank body is made in the form of a straight circular cylinder, and the protective tube mentioned is made either so that it is fixed with its first end to one generatrix of the side wall of this cylinder with free access to the internal cavity of this pipe from this side the first end, while its second end is muffled; or so that said protective tube is fixed with its first end on one generatrix of the side wall of this cylinder, and with its second end on the opposite generatrix of the side wall of this cylinder, so that free access to the internal cavity of this pipe from both ends is provided.

The technical result is also achieved by the fact that the tank body is made in the form of a straight rectangular parallelepiped, and said protective tube is made either so that it is fixed with its first end on one side face of this parallelepiped with free access to the inner cavity of this pipe from the side of this first end, while its second end is muffled; or so that the said pipe is fixed with its first end on one side face of this parallelepiped, and with its second end - on the opposite side face of this parallelepiped, so that free access to the internal cavity of this pipe from its both ends is provided.

Utility Model Implementation

The first embodiment of the tank for bactericidal storage of water (Fig. 1) is characterized in that the tank contains a vertically oriented housing 1 made in the form of either a straight circular cylinder or a straight rectangular parallelepiped. In this case, the housing includes a bottom 2 and a side wall 3 made of an opaque material, for example, stainless steel, as well as a cover 4, hermetically connected to the side wall 3 in its upper part. The lid 4 is made with the possibility of visual control protected from ultraviolet radiation through this lid of the state of the inner surface of the housing 1. In the considered (first) embodiment of the tank, the lid 4 is made entirely of a sheet of monolithic polycarbonate that transmits visible light, but is protected from ultraviolet radiation. This protection is due to the presence on both surfaces of the polycarbonate sheet of protective coatings having the property of absorption (filtration) of ultraviolet radiation. The reservoir also contains nozzles for supplying and discharging water, spaced in height so that the nozzle for supplying water is located in the region of the lid 4, i.e. in the upper part of the housing 1, and the pipe for water drainage is located in the region of the bottom 2, i.e. in the lower part of the housing 1 (nozzles in the figures are not shown). The tank also contains a protective pipe 5, which is located inside the housing 1 in the region of the bottom 2 and parallel to the bottom 2. Moreover, in the considered (first) embodiment of the tank, the pipe 5 is hermetically fixed to the side wall 3 of the housing 1 with the possibility of free access to the inner cavity of the pipe 5 from the outer side of the side wall 3, so that the specified free access is from the right in the picture (i.e. open) end of the pipe 5; while the other (left) end of the pipe is closed, i.e. drowned out. The pipe 5 is made of light-transmitting material, namely, a material that freely transmits light of the ultraviolet and visible ranges, for example, quartz glass, and is intended to accommodate a bactericidal lamp of ultraviolet radiation (the lamp is not shown in the figures). If necessary, visible light sources, for example, LEDs, can be additionally placed in the pipe 5 in order to more intensively illuminate the inner surface of the housing 1 with visible light.

The second embodiment of the tank (Fig. 2) differs from the first embodiment of the cover 4: it is made of an opaque material, for example, stainless steel, and contains a hole (window) 6 in which a sheet of monolithic polycarbonate protected from ultraviolet radiation is hermetically mounted ( similar to the first option).

The third embodiment of the tank (Fig. 3) differs from the first one by the implementation of the protective pipe 5: this pipe with its first end is sealed on one generatrix (or side face) of the side wall 3, and its second end is sealed on the opposite generatrix (opposite side face) side wall 3, so that free access to the internal cavity of the pipe 5 is provided from the outside of the side wall 3 from both ends of the pipe 5.

The fourth embodiment of the tank (Fig. 4) is characterized in that the cap 4 is made similar to the second embodiment described above, and the pipe 5 is made similar to the third embodiment described above.

The use of the tank is as follows (for example, the tank shown in Fig. 1).

Drinking water purified from mechanical and chemical impurities enters the tank through the water supply pipe (the pipe is not shown), where further water in the tank is subjected to a permanent bactericidal treatment using a constantly switched on ultraviolet lamp located in the protective tube 5. The water supply is regulated by an automatic supply system water in order to constantly maintain a given level of water in the housing 1 of the tank. Since the lamp is located in the lower part of the housing 1, the lower volume of water is subjected to processing with maximum intensity, which is actually delivered directly to the consumer at his request through the water outlet pipe (pipe not shown). Inquiries from consumers are usually received irregularly, which is the reason for the relatively long stay of a certain volume of water in the housing 1 of the tank. The absence of water movement for some period of time creates the danger of known stagnant phenomena in the water making the water unsuitable for drinking. However, a constantly working bactericidal lamp located in the protective tube 5 prevents the multiplication of microorganisms in water, exposing the maximum amount of water (lower) to ultraviolet radiation, which is intended for its direct delivery to the consumer upon his request. In this case, the consumer (or service personnel, if any) has the constant ability to monitor the condition of the inner surface of the housing 1, viewing this surface either through the entire cover 4 (Fig. 1, 3), or through the corresponding window 6 in this cover (Fig. 2, 4). This possibility eliminates the need to dismantle the cover 4 in order to control the inner surface of the housing 1, which greatly simplifies the operation of the tank and increases the reliability of this control, without which it is impossible to ensure proper water quality. Maintenance of the tank is also simplified by the fact that the device of the protective tube 5 proposed here greatly simplifies the installation and replacement of the bactericidal lamp, since it completely eliminates the need to dismantle the cover 4 for this purpose; and also makes it possible to easily install an additional source of visible light in order to improve the illumination of the inner surface of the housing 1.
