Description

Oxygen Water Manufacturing Equipment

The present invention relates to an oxygen water production apparatus, and more particularly, to an oxygen water production apparatus capable of containing a high concentration of oxygen in water.

Oxygen water refers to water in which the amount of oxygen dissolved (ie dissolved oxygen) is greater than the average average dissolved oxygen (approximately 7 ppm at room temperature in air). As mentioned above, such oxygen water is beneficial to plants, animals or humans because the amount of oxygen contained in the water is higher than that of ordinary water.

For example, supplying oxygen water to a fishbowl or aquaculture farms not only contributes to the growth of fish growing in a fishbowl or aquaculture farms, but also purifies water that contains feces or other suspended solids as they grow. There is an advantage that can proceed faster by a high concentration of oxygen.

In addition, the use of oxygen water for plant cultivation, the Agricultural Research Institute's research shows that the yield of agricultural products according to plant cultivation increases by more than 10% than when supplying general agricultural water.

In addition, when oxygen water is used as drinking water, oxygen can be supplied to the body even through water, so it may be helpful to the elderly, who are uncomfortable breathing through the respiratory system.

Therefore, it is necessary to actively expand such oxygen water to actively use it for fishing (especially aquaculture) and agriculture.

On the other hand, this advantageous oxygen water production apparatus produces oxygen water in two ways. One is to produce oxygen water by using an electrolysis method, and the other is to produce oxygen water by simultaneously pressurizing water and oxygen to a plurality of partitions in which fine pores are formed.

However, the oxygen water production apparatus using the former method is expensive to manufacture and install, there is a problem that the generated oxygen is generated in the form of bubbles rather than dissolved in the water disappears into the atmosphere.

In addition, the oxygen water producing apparatus using the latter method has an advantage of obtaining a relatively high concentration of dissolved oxygen, but requires a considerably high pressure to increase the concentration of oxygen. In addition, the latter oxygen water production apparatus has a problem that the amount of dissolved oxygen of the produced oxygen water drops sharply in the atmosphere (see FIG. 9), so it is difficult to be utilized in farms or agricultural products cultivators that require a large amount of oxygen water.

The present invention is to solve the above problems, an object of the present invention is to provide an oxygen water production apparatus capable of producing oxygen water containing a relatively small amount of dissolved oxygen changes with time while containing a high concentration of dissolved oxygen.

Preferably, the first rotating body and the second rotating body are respectively installed in succession of two or more sheets, and the first fixing body and the second fixing body are respectively the first rotating body and the second rotating body. It is preferable to be installed in the case so as to correspond to the installation position of the.

The first rotating body, the second rotating body, the first fixing body, and the second fixing body may be disposed so that protrusions of adjacent members are shifted from each other.

In addition, the cover may be further provided with a gas micronization means to generate bubbles when mixing the liquid flowing through the first inlet and the gas flowing through the second inlet.

In addition, the gas atomization means is preferably a filter member provided in the second inlet.

Oxygen water production apparatus of the present invention has the advantage that can produce a high concentration of oxygen water through a relatively simple structure.

In addition, the oxygen water production apparatus of the present invention can not only continuously produce oxygen water, but also change the dissolved oxygen amount of oxygen water by changing the arrangement and arrangement number of the rotating body and the fixed body inside, It can be used in large farms or large agricultural fields that require high oxygen and high concentrations of oxygen.

As a result, as shown in FIG. 16, the dissolved oxygen content of the oxygen water produced by the conventional oxygen water production apparatus rapidly decreased in about one day (about 60%), and after about five days, the dissolved oxygen content of the conventional water was (About 7 ppm). On the other hand, the dissolved oxygen amount of the oxygen water produced by the oxygen water production apparatus of the present invention was reduced by about 20% the next day, about 50% by about 5 days.

Through this experiment, it was found that the oxygen water production apparatus of the present invention lasts a longer amount of dissolved oxygen than the conventional oxygen water production apparatus, but it is confirmed again that the storage period of oxygen water (ideally 5 days) is not very long. Was done.

5.Relationship between Rotation Speed and Dissolved Oxygen (Oxygen Water Production Equipment)

Applicant tried to change the rotation speed of the rotating shaft 130 through the drive means in order to determine the correlation between the rotation speed and the dissolved oxygen amount of the oxygen water production apparatus of the present invention.

As a result, as shown in FIG. 17, it was found that the amount of dissolved oxygen in the water began to increase significantly at 2500 rpm and increased rapidly around 3500 rpm. However, when the rotating shaft 130 is rotated at an excessively high speed, water vapor is generated by friction between water and the rotating body, and therefore, it is preferable to rotate in the range of 3000 to 4000 rpm.

The above-mentioned experimental results are all operating conditions for optimizing the oxygen water producing apparatus of the present invention, but do not specifically limit the features of the present invention, the oxygen water producing apparatus of the present invention and the conventional oxygen water producing apparatus clearly It can be used as a distinguishing factor.

Although the present invention has been illustrated and described with respect to specific preferred embodiments, the present invention is not limited to the above-described embodiments, and those skilled in the art to which the present invention pertains may claim the following utility model registrations. Various modifications can be made without departing from the spirit of the technical idea of the present invention described in the scope.
