Description

Micro bubble manufacturing apparatus {Micro bubble manufacturing apparatus}

The present invention relates to a microbubble generating device, and more particularly, to a bubble by mixing oxygen with water to generate a bubble, and a microbubble generating device capable of generating as many bubbles of the minimum size as possible with simple equipment.

In general, microbubbles refer to very fine ultra-miniature bubbles having a diameter of several tens of micrometers or less. Such fine air bubble particles are used in various applications in the etching and cleaning processes of semiconductor wafers, purification facilities, fish farms, washing machines, and bathrooms.

In particular, when the microbubble is used in the bathroom, air dissolved in water (oxygen bubble) penetrates the skin to effectively remove sebum, hair follicles, and waste products in the pores. In addition, the microbubble itself provides the effect of bathing and massage, so its use is expected to increase in the general home.

Representative of the method of generating the micro bubble is a micro bubble by passing water and air at a relatively high pressure to a decompression section such as an orifice, the air dissolved in the water is broken into a myriad of small particles by the decompression section and discharged to the outside Will generate.

However, in the conventional micro bubble generator, raw water is supplied using a pump for pumping raw water and an air inlet is provided at one side to generate bubbles by mixing the supplied air with raw water.

In this case, in order to generate a large amount of micro bubbles, water and air must be transported at a relatively high pressure. Therefore, separate equipment for mixing the supplied water and air must be provided and a large pump to aspirate a large amount of air. Since the equipment is large, such as using a micro bubble generating device itself has a problem that the installation and operating costs of the equipment is increased.

In addition, the amount of bubbles generated in the air may increase as the amount of oxygen contained in the air increases. Conventionally, the amount of bubbles cannot be freely controlled because the bubble is generated by introducing air in a natural state using a venturi tube. .

In addition, since the air inflow method of the incoming air is naturally introduced through the air inlet, the air pressure is lower than that of the pumped water, so when the microbubble generation device is stopped, the water flows back or the water flows back. There is a problem of blocking the air inlet flows into the.

In addition, conventionally, in supplying bubbles generated in the micro bubble generator, there is a problem in that the bubble supply unit is limited in a range in which the supplied bubbles are distributed as the one side is supplied through an end of the open bubble supply line.

For example, when the microbubble device is used as a water purification device, the bubble discharged from the end of the bubble supply line installed in the water rises to the surface of the water, and the foreign matter floating in the water can be pushed up to the surface to remove it. If the amount of bubbles present is small, it takes a long time to push up foreign matters or cause a problem that cannot push up all the foreign matters distributed in the water.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object of the present invention is to generate bubbles by dropping the water by mixing oxygen and water, the bubble by using the speed and pressure difference of the water To make it happen.

Another object of the present invention is to mix water and oxygen on a water supply line to which water is supplied.

Another object of the present invention is to prevent water from flowing back to prevent the supply of oxygen.

Another object of the present invention is to adjust the amount of oxygen is supplied to control the amount of bubbles generated.

Another object of the present invention is to generate a bubble using a drop of water, so that the drop of water can be generated more than once.

Another object of the present invention is to allow the water to be elevated by the pressure difference to fall again.

Another object of the present invention is to be able to increase the amount of bubbles generated by colliding with the falling water.

Another object of the present invention is to supply the bubble evenly throughout the place to supply the bubble through the bubble supply line.

As described above, the microbubble generating device for achieving the object of the present invention is a microbubble generating device for generating microbubbles in water, the raw water supply for supplying water, and supplying oxygen to the water supplied from the raw water supply An oxygen supply unit, a mixing unit for mixing raw water supplied through the raw water supply unit and oxygen supplied through the oxygen supply unit, and bubble generation to generate bubbles by using pressure and a speed difference from water mixed in the mixing unit And a bubble supply unit for supplying the bubble-generated water from the bubble generating unit, wherein the mixing unit is supplied to the raw water supply line by the raw water supply pump from the raw water supply unit and through the oxygen supply line from the oxygen supply unit.

Thus, according to the present invention, bubbles are generated by mixing water and oxygen, and bubbles are generated by a pressure and a speed difference, thereby generating more bubbles even when using pump equipment having the same capacity.

In addition, since the present invention does not require a separate mixing equipment by mixing water and oxygen through a mixing line on the raw water supply line to which water is supplied, the mixing process is simple and the overall volume of the equipment is reduced.

In addition, since the supply pressure of oxygen is always higher than the pressure at which the water is supplied, the present invention has an effect of preventing water from flowing back by the pressure of the supplied oxygen even when the water supply is suddenly stopped.

In detail, the pressure of the oxygen supplied from the oxygen generator 21 is operated higher than the pressure of the raw water supply pump 11 so that the supply of water was suddenly stopped due to a malfunction of the raw water supply pump 11 during the bubble generation process. This is to prevent the reverse flow of water, and to prevent the oxygen connection hole 31c of the mixing line 31 from being blocked by the reverse flow of water.

4 is a view showing a bubble generating part of the micro bubble generating apparatus according to the present invention, Figure 5 is a view showing a bubble supply part of the micro bubble generating apparatus according to the present invention.

Meanwhile, as illustrated in FIG. 4, the bubble generator 40 is installed inside the outer container 41 and the outer container 41 serving as the main body of the bubble generating unit 40, and the aforementioned mixing tank 35 is described above. ) Is installed to surround the outside of the bubble generating line 43 and the bubble generating line 43 in which the water mixed with oxygen supplied through the mixing supply line 37 connecting the bubble generating unit 40 falls. It consists of the inner cylinder 45, the 2nd inner cylinder 47 and the discharge line 49 provided between the outer cylinder 41 and the 1st inner cylinder 45. As shown in FIG.

The bubble generating line 43 is pumped from the raw water supply pump 11 to have a constant pressure and to generate bubbles through the collision of water and pressure drop while the oxygen-mixed water falls first.

The first barrel 45 drops from the bubble generating line 43 to receive the bubble-generated water and re-drops it so that the water contained in the first barrel 45 is lifted to raise and lower the water of the first barrel 45. Overflow to the outside.

The second barrel 47 generates bubbles while the water overflowing to the outside of the first barrel 45 falls again, and collides with the second barrel 47 provided to be spaced apart from the first barrel 45 to further collide with each other. Create a bubble. Here, the second speed cylinder 47 is preferably formed so that the lower side is open to communicate with the discharge line 49 to be described later.

First, the raw water supply pump 11 and the oxygen generator 21 are operated to apply pressure to water and oxygen so that water and oxygen are supplied to the mixing line 31 on the raw water supply line 13. At this time, since the oxygen supply pressure of the oxygen generator 21 is higher than the operating pressure of the raw water supply pump 11 is to flow back to the raw water supply pump 11 by the pressure of the oxygen continuously supplied even if the water is suddenly stopped. Is prevented.

Here, it is possible to adjust the amount of raw water supplied by operating only a part of the plurality of raw water supply pumps 11, it is of course possible to adjust the amount of oxygen supplied to the mixing line 31 through the controller (25).

The supplied water and oxygen are mixed on the raw water supply line 13 through the mixing line 31 in which the raw water line 31a and the oxygen line 31b are formed and loaded in the mixing tank 35.

Water and oxygen loaded in the mixing tank 35 is supplied to the bubble generating line 43 installed inside the outer cylinder 41 to make the first drop, and the first drop of water and oxygen is the first velocity cylinder 45. It is loaded in and then falls again. Here, the water, the pressure of which is increased by the operating pressure of the raw water supply pump 11 during the first drop, drops and generates bubbles by collision due to pressure and speed difference applied while falling from the bubble generating line 43. Water is introduced into the first barrel 45, and is elevated above the first barrel 45, overflowing and falling again, causing re-collision with the second barrel 47 to further generate bubbles.

Water generated through the above process is supplied to the fish farm (not shown) through the discharge line 49, the bubble through the bubble supply line 51 in which the bubble supply hole 53 is formed on the entire outer surface Bubbles generated by the generator 40 may be uniformly supplied to the entire fish farm by the pressure and speed of the water. At this time, it is a matter of course that the amount of bubbles supplied can be adjusted by controlling the opening and closing of the bubble supply hole (53).

If air is supplied to the entire fish farm, foreign matters floating in the water of the fish farm will float to the surface, and the foreign matters suspended in the water will be removed to purify the water quality of the fish farm and increase the amount of dissolved oxygen in the water to increase the yield of the fish farm. Can be. In particular, since the size of the supplied bubble is small and the amount is large, there is an advantage that all the small foreign matters can be suspended.
