Description

Alkaline Water Generation System [0002]

The present invention relates to an alkaline-reduced water producing system, and more particularly, to an alkaline-reduced water producing system capable of smoothly generating alkaline-reduced water by removing scales generated on the surface of a reducing apparatus, discharging water from a reducing apparatus Thereby reducing the oxidation of the reducing unit.

In recent years, it has become widely known that alkaline-reduced water has a positive effect not only on humans but also on livestock and the like by improving immunity. Various attempts have been made to supply alkaline-reduced water as drinking water for cattle such as cattle, pigs or chickens, In order to use the alkaline-reduced water producing system for livestock, that is, for farm use, a large amount of alkaline-reduced water must be produced economically and quickly within a short period of time.

The present inventor has proposed a device for producing an alkaline-reduced water and has received a patent registration (Patent No. 1570861). This device has a structure in which a plurality of supports in the form of a disk made of an alkali or an alkaline earth metal are parallelly arranged in a vertical direction And the water flowing between the supports successively flows from the inside to the outside in an alternating manner from the outside to the inside so that the flow velocity of the water is decreased and the collision due to the vortex action is caused to increase the reaction speed with the carrier, So that a large amount of alkali-reduced water can be generated and supplied in a short period of time, which is suitable for use as a livestock.

However, in the conventional alkaline-reduced water producing apparatus including the alkaline-reduced water producing apparatus of the above-mentioned Patent Literature, generally, when used for a long period of time, a scale similar to that of an oxide film is generated on the surface of the carrier and the reducing power is rapidly lowered, It is necessary to recover the reducing power of the carrier by removing the scales generated on the surface of the carrier by using acetic acid or citric acid and then use the alkali reducing water produced in the patent document The apparatus does not have such a scale removing means, so that the user manually removes the scale by cleaning the surface of the carrier by supplying acetic acid or the like into the apparatus manually as needed. In this case, when the scale is manually removed, texture It is not easy even having to manually progress the series of processes as well as vary.

In addition, during the generation of alkali-reduced water, a blackout occurs or a failure occurs to stop the operation of the apparatus, so that water remains inside the apparatus. When the water remains in contact with the carrier, the carrier made of an alkaline earth metal rapidly There is an inconvenience in that it is necessary to use the oxide after removing the oxide from the carrier or to change the carrier again.

<Normal operation mode: Alkali-reduced water generation operation mode>

When the alkaline reducing water producing system of the present invention is operated in the 'normal operation mode', that is, the 'alkaline reduced water generating operation mode', first, as shown in FIG. 9, by the control of the controller 80, The water is supplied to the three-way valve, that is, the first, second, and third reservoirs 30 and 30 so as to sequentially pass the supply pipe 30, the first reducing device 20A, the second reducing device 20B, the recovery pipe 40, The circulation pump P is operated in this state so that the water stored in the storage tank 10 is supplied to the supply pipe 30 (30A, 30B) The alkali reducing water is generated by passing through the first reducing unit 20A and the second reducing unit 20B through the return pipe 40 and then returned to the storage tank 10 through the return pipe 40, This alkaline-reduced water generating operation is repeatedly performed until the water in the storage tank 10 reaches a predetermined pH, and then, when the set pH is reached The operation of the circulation pump P is stopped and the generation of the alkali reduced water is stopped.

If the water inside the first and second reducing apparatuses 20A and 20B is kept in contact with the carrier after the operation of generating the alkaline reducing water is stopped as described above, the carrier made of the alkaline earth metal may be rapidly oxidized In order to prevent this, in the present invention, the water remaining in the first and second reducing apparatuses 20A and 20B is completely removed after the generation of the alkali reduced water is stopped. This process is controlled by the control unit 80, The opening directions of the first and second drain valves 60A and 60B are adjusted so that the first and second reducing units 20A and 20B are connected to the drain pipes 31 and 41, The air supply fan 26 is operated in a state in which the open / close valve 27 provided in the first and second reducing devices 20A and 20B is opened, whereby the outside air is supplied to the inside of the first and second reducing devices 20A and 20B, The water remaining inside the apparatuses 20A and 20B flows to the outside through the water pipes 31 and 41 The normal operation mode is ended by the next still discharged, first, the drying occurs in portrait of the second reduction unit (20A, 20B).

<Cleaning operation mode: Scale removal operation mode>

As described above, when the apparatus for producing an alkaline-reduced water is used for a long period of time, scale is generated on the surface of the carrier, so that the rate of generation of the alkaline-reduced water is lowered periodically. When the rate of generation of the reduced water becomes lower than a predetermined rate, In the present invention, the washing operation mode is provided so that the washing operation can be automatically performed. In the present invention, even if the washing operation mode is continuously performed, When the pH of the reduced water flowing into the storage tank 10 from the first and second reducing apparatuses 20A and 20B is maintained at a preset pH or lower for a predetermined time or more, And the washing operation mode of the present invention is carried out as described below Spinal cord preparation step, washing step, subjected to a rinsing step in turn.

When the pH measured by the pH sensor 11 is lower than a predetermined pH, the controller 80 operates the circulation pump P Water is supplied to the first and second reducing units 20A and 20B to generate alkali reduced water and when the measured pH is higher than a preset pH, the operation of the circulation pump P is stopped to generate alkali reduced water The control unit 80 controls the opening directions of the first and second drain valves 60A and 60B to stop the first and second reducing units 20A and 20B, The second and third reducing devices 20A and 20B are connected to the drain pipes 31 and 41 by blowing outside air to the first and second reducing devices 20A and 20B, And the water is controlled to be removed.
delete delete The method according to claim 1,
The external air injected into the first and second reducing devices 20A and 20B is supplied to the air supply fan 26 provided in the air supply pipe 25 connected to the first and second reducing devices 20A and 20B By weight.
The method according to claim 1,
Wherein the control unit (80) is set to operate in three operation modes: a normal operation mode, a cleaning operation mode, and an electrostatic operation mode.
The method of claim 5,
Wherein the washing operation mode comprises washing water preparing step, washing step, and rinsing step.
The method according to claim 1,
All components of the system including the storage tank 10, the first and second reducing devices 20A and 20B, the circulation pump P and the control unit 80 are integrally installed inside the casing, And an electric heater for preventing the alkali water is installed and automatically turned on and off according to the ambient temperature.
