The technical field to which the invention relates.

The present invention relates, generally, to a device for the formation of colloidal silver, and more specifically, to a washing machine equipped with a device for the formation of colloidal silver, which has an outlet, an advanced form and its location, thus avoiding the presence of water in the device of the formation of colloidal silver.

Background of the invention

Usually washing machines are devices for washing Laundry placed in the washing tank by mixing the clothes inside the washing tank in the presence of water for washing and detergent.

A washing machine includes a motor, water tank, washing tank, the pulsator and the feeder detergent. Water tank contains water for washing. The washing tank is mounted rotatably in the water tank and linen, which will wear off, is placed in the washing tank. The pulsator is rotatably from the bottom of the washing tank and linen mixes in water for washing. Feeder detergent is provided in a predetermined position above the water tank and supplies the detergent to the wash water supplied from an external water source.

Washing machine works as follows. Cyclable is loaded into the washing tank. Water for washing, mixed with detergent, filed out of the feeder detergent, served in a water tank. When the motor is running in this mode, the pulsator is rotated in alternating directions for mixing linen in water for washing, thus erasing linen.

Was recently established a washing machine equipped with a device for the formation of colloidal silver to add silver ions to the wash water, while water for washing is supplied in a water tank, thus forming colloidal silver, which kills germs on clothes during washing. Therefore, a washer device of the formation of colloidal silver has antimicrobial and bactericidal effects.

The device of the formation of colloidal silver contains a pair of silver plate, to which is applied the voltage. When water for Laundry passes through the silver plate, silver plate dissociate silver ions to the wash water through electrolysis of silver plates thus formed colloidal silver and is served in a water tank.

Washing machine with a device for the formation of colloidal silver wash clothes with water for washing, in which the dissolved silver ions selected concentration, thus killing germs on Belle is.

In this case, the device of the formation of colloidal silver contains the inlet opening through which water for washing is supplied in a device of the formation of colloidal silver, and an exhaust hole through which water is drained from the washing device of the formation of colloidal silver. The outlet device of the formation of colloidal silver is connected with the inlet of the feeder detergent through a connecting pipe, so that the device of the formation of colloidal silver communicates with the feeder detergent.

Thus, the water for washing is supplied through the inlet opening in the device of the formation of colloidal silver, mixed with silver ions, dissociirovati from silver plates by electrolysis of silver plates. After this water for washing, containing silver ions, is fed into the feeder detergent through the outlet device of the formation of colloidal silver.

However, the normal formation of colloidal silver has a drawback in that the outlet opening has a round shape to drain water wash containing silver ions, in the drawer, detergent, so that a large amount of water may remain in the device of the formation of colloidal silver, when the ends of the hearth is water.

In the detailed description, when it comes to water supply, water for washing evenly passes through the circular discharge opening in the pressure water wash and then fed into the feeder detergent. However, while stopping the supply of water and the water for washing is not available in the device of the formation of colloidal silver, water pressure for washing, supplied in a device of the formation of colloidal silver acts evenly on the entire cross-sectional area of the round outlet, as a result, the outlet water film is formed by the action of the capillaries. Thus, water for washing can not fully merge from the media education colloidal silver, and some water for washing may remain in the device of the formation of colloidal silver.

Essentially, when a certain amount of water for washing remains in the device of the formation of colloidal silver after termination of the water supply, silver plate immersed in water for washing. In this case, the silver plate can be subjected to corrosion by the reaction between the silver plates and water for washing. In addition, impurities can be deposited on silver plates, thereby preventing dissociation of silver ions from the silver plates. In this the m case, the desired sterilizing effect is not achieved, and lifetime silver plates undesirable shrinking.

The motor (not shown) provided in a predetermined position under the water tank for rotation of the washing tank 3 and the pulsator.

In addition, the device 10 supply of detergent and the device 20 education colloidal silver is provided in a given position above the tank for water or washing tank 3 to add detergent and silver ions to the wash water supplied from an external source of water before entering the water tank. In the detailed description of the water for washing is supplied to the device 20 of the formation of colloidal silver through a hose 4 water supply, which is connected with an external source of water, and the silver ions of a given concentration are added to the wash water. After this water for washing, containing silver ions, passes through the device 10 supply of detergent. Thus, the water for washing is supplied in a water tank when mixed with detergent.

Essentially, when detergent and silver ions are added to the wash water, linen erased due to cleaning is th effect of detergent, at the same time on linen killing germs due to the antimicrobial and bactericidal action of silver ions.

Bactericidal action of silver will be described briefly below. Silver is not tolerated by the microbes in contrast to other conventional antibiotics. In addition, silver is a very safe substance, since silver is not toxic. Thus, when washing linen using silver lingerie is becoming more hygienic due to the antimicrobial and bactericidal effects of silver. Therefore, when a specified amount of silver ions dissolved in water for washing using electrolysis, and water for washing containing silver ions, served in a water tank, the microbes on linen killed when washing linen using water for washing containing silver ions.

Figure 2 is a perspective view of the device of the formation of colloidal silver in figure 1. As shown in figure 2, the device 20 education colloidal silver includes a housing 21 of silver ions, the cover 22 and a pair of silver plates 23. In the housing 21 of silver ions is formed a passage 24 for the water passing through the water for washing, and created space for electrolysis of silver plates 23. The cover 22 closes the upper part of the housing 21 of silver ions. Silver plate 23 is installed between the housing 21 of silver ions and kryskow and provide silver ions water for washing.

Contact 23a is made as one piece on the upper end surface of each silver plate 23, so that each of the silver plate 23 is electrically connected with a source of electricity through a wire (not shown). Each silver plate 23 is supported by the cover 22, while its contact 23a protrudes from the cover 22 to the specified length.

The inlet opening 25 is formed on the end surface of the cover 22, so that the hose 4 water supply (see figure 3)connected with an external water source, is installed in the inlet opening 25. On the end surface of the housing 21 of silver ions, which is far from the inlet 25, is provided for the exhaust pipe 26 (see figure 3), so water for washing containing silver ions, served from the housing 21 of silver ions in the device 10 of the feed of detergent through the discharge pipe 26.

The device 10 filing detergent includes a housing 11, a container 12 for detergent and a device 14 for injection of water. The housing 11 is open at its front part. Capacity 12 detergent retracts and extends through the open front of the chassis 11 slidable and contains detergent. The device 14 for injection of water is provided in the housing 11 of the device 10 supply of detergent and located above the bottom surface 12a capacity is 12 detergent.

Thus, the water for washing is supplied into the housing 11 through the outlet pipe 26 of the device 20 education colloidal silver is injected from the device 14 for injection of water into the tank 12 for the detergent to the water for washing was mixed with detergent. After this water for washing, containing silver ions and detergent comes in a water tank through the gap formed between the bottom surface 12a of the vessel 12 for detergent and the housing 11, thus wetting underwear.

In the device 10 supply of detergent and the device 20 education colloidal silver, made as described above, the device 10 supply of detergent is attached to the upper part of the housing 1 through the holes for the hook, which is formed on the brackets 13 are provided on both side walls of the housing 11, and the device 20 education colloidal silver is attached to the upper part of the housing 1 through the screw holes that are formed on brackets 27 provided on the outer surface of the device 20 of the formation of colloidal silver.

Figure 3 is a perspective partial view in section of the connection between the device formation of colloidal silver and feeder detergent. As shown in figure 3, the device 20 of the formation of colloidal silver are connected as one with the moustache is the device 10 supply of detergent in a simple design through the discharge pipe 26 for the communication device 20 of the formation of colloidal silver with the device 10 supply of detergent and connective part 30 provided between the device 20 of the formation of colloidal silver and the device 10 supply of detergent.

The exhaust pipe 26, having a cross section in the shape of an ellipse, is connected in one piece with the device 10 supply of detergent, thus the exhaust pipe 26 is used as a connecting pipe for communication device 20 of the formation of colloidal silver with the device 10 supply of detergent. The exhaust pipe 26 also performs the function of an inlet pipe for supplying water for washing device 10 supply of detergent.

Thus, the water for washing is supplied through the hose 4 feed water passes into the passage 24 for water body 21 of silver ions when mixed with silver ions, disocyanate from silver plates 23. After that, water for washing, containing silver ions, served in the device 10 of the feed of detergent through the discharge pipe 26.

The outlet 40 of the device 20 of the formation of colloidal silver, with which the exhaust pipe 26 is connected as a whole, has the shape of an ellipse. In addition, the discharge opening 40 is formed on the surface of the body 21 of silver ions and passes from the lower end surface to its upper end surface. The shape and arrangement of the outlet openings 40 will be described below with reference to figure 4.

Figure 4 represent the screens view in section along the line IV-IV of figure 3 to illustrate the shape and location of the outlet openings of the formation of colloidal silver. As shown in figure 4, the discharge opening 40 formed in the lower housing 21 of silver ions. Water for washing, sesenna with silver ions when passing through the passage 24 for water (see figure 3) of the housing 21 of silver ions is fed into the device 10 supply of detergent through the outlet 40.

The outlet 40 is designed so that its vertical length (i.e. height) differs from its horizontal length (i.e. width), thus preventing the presence of water for washing in the housing 21 of silver ions at the termination of the water supply device 20 to the formation of colloidal silver.

Preferably the outlet 40 may be in the form of an ellipse and can be carried from the lower end surface of the upper end surface of the housing 21 of silver ions. Thus, the vertical length of the exhaust hole 40 more horizontal length of the outlet 40.

Essentially, since the exhaust hole 40 has the shape of an ellipse, a vertical length greater than the horizontal length, the water pressure is distributed unevenly through the outlet 40 when the water flow stops. In this case, the water pressure acting on the upper end of the outlet 40, is minimized, thus ensuring the passage of atmospheric air through the upper end of vypusk the th hole 40.

This shape and arrangement of the outlet openings 40 prevents overlap of the outlet 40 of the water film due to the action of the capillaries after the termination of the water, thus preventing the presence of water for washing in the housing 21 of silver ions.

In addition, preferably, the vertical length or height H1 of the outlet 40 and the height H2 of the housing 21 silver ions are in a predetermined relation to each other, thus preventing the formation of a water film on the outlet 40 and providing the addition of silver ions optimal concentration to the wash water passing through the housing 21 of silver ions.

In more detail, when the height H1 of the outlet 40 is considerably greater than the height H2 of the housing 21 of silver ions, the water passes through the housing 21 of silver ions too quickly. In this case, to the wash water is added a small amount of silver ions. On the contrary, when the height H1 of the outlet 40 is considerably smaller than the height H2 of the housing 21 of silver ions, can form a water film and an overly large amount of silver ions is added to the wash water.

Preferably, the height H2 of the housing 21 of silver ions and the height H1 of the exhaust openings 40 are in the ratio of approximately 3:2, thus ensuring the addition of silver ions optimal concentration input for washing and preventing the formation of a water film.

In the device 20 of the formation of colloidal silver, made as described above, a pair of silver plate 23 is electrically connected with the power source through the contacts 23a silver plate 23. Thus, when the application of a specified voltage to the silver plates 23 and the water supply for washing device 20 education colloidal silver through the inlet opening 25 (see figure 2) covers 22 water for Laundry passes through the silver plate 23 while passing through a passage 24 for the water body 21 of silver ions. At this time, silver ions dissociate from the silver plate 23 through the electrolysis of silver plates 23. Thus, silver ions of a given concentration are added to the wash water.

Water for washing containing silver ions, sequentially passes through the exhaust port 40 and the exhaust pipe 26 and fed to the device 10 supply of detergent. When passing water wash through the tank 12 for the detergent, the detergent is added to the wash water. Thus, water for washing, containing silver ions and detergent comes in a water tank.

When applying the optimal amount of water for washing in a water tank and the water flow stops, the shape and arrangement of the outlet openings 40 in accordance with the present invention prevent the formation in the Noah film on the outlet 40, thus ensuring complete discharge of water for washing of the hose 4 water supply and housing 21 of silver ions through the exhaust port 40 and the exhaust pipe 26 in the device 10 supply of detergent.

FIELD: food and pharmaceutical industries; water filtration.

SUBSTANCE: the invention presents a method of purification of liquids and is dealt with filtration, in particular with the methods of purification of liquids from impurities. It may be used in the systems of industrial and household water supply in food and pharmaceutical industries. The method of liquids purification includes a partial shutting off a trunk of the unpurified liquid, delivery of the unpurified liquid in a trunk of the unpurified liquid and to the filtration element - in a trunk of purified liquid. Before the unpurified liquid delivery into the trunks of the unpurified and purified liquids it is passing through an ejector. The technical result is an increased convenience in operation and productivity of purification due to simultaneous outflow of both purified and unpurified liquids without decrease of a flow area of the purified liquid trunk running cross-section.

FIELD: water-supply engineering.

SUBSTANCE: invention relates to methods of removing hardness salts from regenerates and can be used in water treatment processes in heat-and-power engineering, chemical, petrochemical, food, and other industries provided with ion-exchange water-desalting filters. Method is accomplished by precipitation of hardness salts involving recycle of precipitate treated by alkali solution followed by passage of supernatant through H-cationite filter. Treated precipitate accumulated in preceding settling cycles is recycled into regenerate and settling-subjected solution is passed through cationite filter to produce purified sulfuric acid further used for regeneration of H-cationite filters in water-treatment cycle. Precipitate is treated with alkaline regenerate from OH-anionite filters or with alkali solution obtained from electrolysis of regenerates with pH not below 11. Amount of regenerate introduced into accumulator-settler should be at least 20 kg/m3.

EFFECT: excluded liming procedure, preserved initial (after regeneration of filters) content of sulfate ions in sulfuric acid, reduced consumption thereof during preparation of regeneration solution, and excluded discharge of sulfate ions unto water objects.
