Description

Low power micro bubble generator

The present invention relates to a low-power micro-bubble generating device, and more specifically, to a low-power micro-bubble generating device capable of saturating oxygen at a high concentration without using a separate stirring means as well as miniaturizing the device with a simple structure. will be.

In general, water, oxygen, and other gases are required for plant growth, and oxygen is the most important gas among various gases required for plant growth, and the reason for plowing is air in the soil, that is, oxygen. It is to blow.

Good soil is a soil with an isolated structure that has water retention and breathability. These soils create a pleasant environment at the root of the plant and have a good effect on the growth of the plant.

To this end, conventionally, sprinklers, spraying hoses, and drip hoses are used to irrigate the air to be supplied to the root region (near the root) through the pores in the soil along with water flowing into the ground.

However, this is simply to inject water into the air and then to be supplied into the ground. As a sufficient amount of oxygen is not saturated in the supplied water, there is a limit to satisfy the oxygen demand required by the plant.

Accordingly, a method has been proposed in which oxygen water generated by dissolving oxygen in water in advance is sprayed onto the plant to satisfy the amount of oxygen required by the plant.

On the other hand, as a general method for generating oxygen water, there is a method of dissolving oxygen by increasing the contact area between oxygen and water by introducing oxygen into the water through a submerged porous diffusion member or a venturi nozzle.

However, the above method is not only economical because oxygen dissipation efficiency is remarkably low compared to the supply of oxygen, which consumes a lot of oxygen, and there is a disadvantage in that oxygen dissolved in water is easily degassed, thereby reducing the amount of oxygen required by plants. There is a limit to generating dissolved oxygen water at a high concentration that can be satisfied.

For this reason, in recent years, in order to increase the amount of dissolved oxygen in water, a pressure dissolving method in which water and oxygen are filled in a sealed container and stays in a pressurized state for a long time to dissolve is widely used.

However, the pressure dissolving method as described above requires a solid tank, a high-lift pump, and a high-pressure oxygen tank, and thus, there is a problem in that the volume of the device is large and heavy, and above all, the unit production cost of oxygen water is high.

Then, the outer body 12 is formed to extend downward from the inner top of the region where the outlet 12b is formed, and divides the second space portion S2 into a first moving path F1 and a second moving path F2. The partition wall 12c is further formed.

The partition wall 12c as described above is the first movement path (F1) and the second movement before some of the oxygen water flowing into the second space portion (S2) through the inlet (12a) is discharged to the outside through the outlet (12b) By increasing the residence time of the oxygen water by passing through the furnace (F2), it serves to ensure that sufficient time for the undissolved oxygen to be more soluble in water is secured.

The rotation induction part 20 is a cylindrical shape of the hollow S, and a circular jaw 21 is protruded in an outer direction along a circumferential direction on one side of the outer surface of the upper end, and such a circular jaw 21 is a locking jaw 11c of the inner body 11 ) And is accommodated in the first space portion S1.

The inner hollow S of the rotation inducing portion 20 includes a first section T1 in which the inner diameter decreases from the bottom to the upper direction, and a second section in which the inner diameter increases in the upper direction from the end of the first section T1 ( T2).

And, the outer surface of the rotation guide portion 20 corresponding to the first section (T1) is formed to be spaced apart at regular intervals along the up and down and circumferential directions, a plurality of inlet holes communicating with the inner hollow (S) of the rotation guide portion 20 (22) is formed, a plurality of inlet holes 22, as shown in Figure 4, it characterized in that the inner hollow (S) of the rotation inducing portion 20 is formed to be curved in the direction of the outer peripheral surface from the inner peripheral surface is formed.

Here, the inner hollow (S) of the rotation inducing portion 20 provides a path through which the water flowing into the first space portion (S1) through the raw water inlet (11a), a plurality of inlet holes 22 supply oxygen Provides a path through which the oxygen introduced into the first space portion S1 through the sphere 11b flows into the inner hollow S of the rotation induction portion 20.

The rotation induction unit 20 as described above rotates the water flowing into the inner hollow S through the oxygen flowing through the plurality of inlet holes 22 to form a vortex, thereby splitting the oxygen into microbubbles, It plays a role of dissolving oxygen in water to produce oxygen water.

The pressure feeding part 30 is coupled so that the lower end of the impeller 32 is rotatably installed so as to shield the upper part of the first space part S1, and one side of the upper end of the outer body 12 through the connecting pipe 50 ( It is connected to 12a) as a means for pressurizing the oxygen water generated by the rotation inducing section 20 to the second space portion S2 of the external body 12, the housing 31, the impeller 32 and the power means ( 33).

The housing 31 has a cylindrical shape, and a suction port 31a is formed at a lower end, an outlet 31b is formed at one side of the upper end, and a lower end where the suction port 31a is formed is coupled to shield the open upper part of the inner body 11.

At this time, the oxygen water generated in the first space portion (S1) is introduced through the inlet (31a) and collides with the rotating impeller (32) so that oxygen that is not dissolved in water can be better dissolved in water. Once more finely divided into microbubbles, more oxygen can be dissolved in water.

Accordingly, the present invention makes it possible to generate oxygen water saturated with dissolved oxygen at a high concentration.

And, the power means 33 is to provide the rotational force of the impeller 32, a general motor can be used.

In addition, according to the present invention, when the lower portion of the pressure-feeding portion 30 is detachably coupled to the open upper portion of the inner body 11, the replacement of the pressure-feeding portion 30 is required, it can be easily replaced and maintained. There is an advantage of easier maintenance.

On the other hand, the pressure-transmitting portion 30 further includes a gripping wire 34 that is bent and extended upward from one side surface so that it can be easily installed in an existing water tank having a deep water depth.

5 is a schematic cross-sectional view for explaining the operation of the low-power micro-bubble generating apparatus according to an embodiment of the present invention, and FIG. 6 is for explaining the operation of introducing oxygen into the rotation inducing part according to an embodiment of the present invention It is a drawing.

Referring to Figures 5 and 6 to describe the operation of the low-power micro-bubble generating device 1 according to an embodiment of the present invention, the first space portion (S1) of the inner body 11 through the raw water inlet (11a) The water flowing into the air is introduced into the hollow S of the rotation induction unit 20 by the pressure of oxygen flowing into the first space part S1 of the inner body 11 through the oxygen supply port 11b.

Then, the water introduced into the hollow S of the rotation inducing portion 20 moves to the upper portion of the first section T1 in which the inner diameter is narrowed, so that a pressure drop occurs as the speed increases, and accordingly the first The oxygen introduced into the space part S1 is introduced into the hollow S of the rotation guide part 20 through a plurality of inlet holes 22 formed on the outer surface of the rotation guide part 20.

It is easily broken into microbubbles.

Accordingly, as oxygen is more easily dissolved in water, oxygen water containing high concentration of dissolved oxygen is generated.

On the other hand, when the oxygen water generated by the rotation induction unit 20 moves upward by the pressure transmission unit 30 and flows into the suction port 31a of the pressure transmission unit 30, the rotation induction unit 20 does not dissolve in water. Unsuccessful oxygen also moves with it.

At this time, as the oxygen that is not dissolved in water flows into the suction port 31a of the pressure-feeding unit 30, it collides with the vertical blades of the impeller 32 and is microscopically broken in the form of micro bubbles that are easily soluble in water. More oxygen is dissolved in water, resulting in a larger amount of oxygen water.

Then, the oxygen water flowing into the suction port 31a of the pressure feeding unit 30 passes through the discharge port 31b of the pressure feeding unit 30, the connecting pipe 50, and the inlet 12a of the external body 12 to the external body ( After flowing into the second space portion S2 of 12), it flows out through the outlet 12b.

At this time, some of the oxygen water flowing into the second space portion S2 of the outer body 12 is first flow path F1 divided by the partition wall 12c before flowing out to the outside through the outlet 12b. And as the residence time increases while passing through the second transfer path F2, it is possible to secure sufficient time for more oxygen to be dissolved in water.

In addition, oxygen that has not been dissolved in water that has been introduced into the second space portion S2 of the outer body 12 is floated to the upper portion, and then the first space portion of the inner body 11 through the bypass hole 11d. It will be re-inflowed to (S1).

As described above, the present invention is a high-pressure pump and a high-pressure tank essential to the conventional pressure dissolving method as the oxygen introduced by the rotation induction unit having a simple structure is saturated at a high concentration while being split into a micro bubble form that is easily soluble in water. Due to the simple structure that is not required separately, it is possible not only to downsize the device, but also to generate oxygen water containing a high concentration of dissolved oxygen without using a separate stirring means.

In addition, the present invention does not require a separate installation space for the installation of the high pressure pump and the high pressure tank because the high pressure pump and the high pressure tank used in the conventional pressure dissolving method are not separately required, and the high pressure pump and the high pressure tank are not separately required. Due to the simple structure, it can be installed and used directly in the existing water tank through the gripping wire, thereby providing convenience to the user.
