Description

Multi-cavitation device {MULTI-CAVITATION APPARATUS}

The disclosed content is that when a fluid is perfused into a pipe including a venturi part that decreases in cross section and then increases again, cavitation in the form of a water vapor bubble is generated, expanded, and collapsed by a pressure difference before and after the venturi part. It relates to a cavitation device that extracts medicinal herbs from plants such as lavender oil and chaga mushrooms.

Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

In general, when fluid flows through a pipe including a venturi section that decreases in cross section and then increases again, the velocity of fluid is slowed down and pressure rises in the portion where the cross section is reduced, and the fluid velocity increases and pressure in the portion where the cross section increases. At this time, cavitation in the form of numerous small water vapor bubbles is generated due to the difference in pressure on both sides, and collapses after expansion occurs.

Particularly, at the outlet side where the cavitation in the form of water vapor bubbles collides with each other in several directions, a shock wave is generated, which not only generates a considerably high pressure and temperature, but also forms free hydroxyl radicals.

As described above, the hydraulic cavitation device uses the force generated by generating, expanding, and collapsing cavitation in the form of water vapor bubbles as the fluid flows through a pipe including a venturi part that decreases in cross section and then increases again. This makes it possible to manufacture biodiesel, emulsify emulsion oil, cosmetics, mayonnaise, etc., or to perform other water treatment, for example, scale removal of cooling towers, particle pulverization, and the like.

On the other hand, in order to extract a specific component from a plant, a method using a high-temperature medicinal bath extraction or a chemical solvent has been used. However, such a conventional method requires a pretreatment process of finely pulverizing the leaves or mushrooms of a plant, which is a raw material, and has a disadvantage in that it is cumbersome to use a high temperature medicinal bath or chemical solvent.

Therefore, the definition should be made based on the contents throughout the present specification.

1 to 3 illustrate diagrams according to an embodiment of the disclosed content. 1 is a conceptual diagram, and FIGS. 2 and 3 are detailed views.

Hereinafter, a constituent member of the multi-cavitation apparatus 1 according to an embodiment of the present disclosure and an operation relationship thereof will be described in detail with reference to FIGS. 1 to 3.

In the multi-cavitation device 1 according to an embodiment of the disclosure, a supply line 11 through which raw materials and a solvent are supplied is connected to one side, and a driving motor 12 is positioned on the other side, but a fixed saw blade 13 is located on the inner side. The rotary cavitation unit is provided with a rotary saw blade 14 connected to the driving motor 12 on the other side of the inside to pulverize raw materials and solvents introduced through the supply line 11 and extract primary components. (10) And, a first discharge line 20 connected to the rotary cavitation unit 10 to discharge and flow the treated material obtained by pulverization and primary component extraction, and the first discharge line 20 at one side thereof. The treatment material is connected to the inside, and a cavitation generating space part 31 is formed therein, and a vortex forming screw 32 is provided behind the cavitation generating space part 31 to be internal through the first discharge line 20. A vortex cavitation unit 30 for extracting a secondary component by passing through the cavitation generating space 31 after the treated material introduced into the vortex forming screw 32 is rotated by the vortex forming screw 32, and the vortex cavitation unit ( 30) It includes a second discharge line 40 connected to one side to discharge the processed material for which the secondary component has been extracted.

First, referring to FIG. 1, a rotary cavitation unit 10 is provided. In the rotary cavitation unit 10, flowers, leaves, seeds, roots, and alcohol and carbon dioxide, which are raw materials, are added together through the supply line 11 to cause the raw materials to be pulverized and mixed with a solvent, and cavitation occurs. It plays a role in allowing the primary ingredient extraction to take place.

This rotary cavitation unit 10 is connected to a supply line 11 through which raw materials and solvent are supplied to one side thereof, and a driving motor 12 is positioned on the other side, but a fixed saw blade 13 is provided on one side of the rotary cavitation unit 10 and a fixed saw blade 13 is provided on the other side. A rotating saw blade 14 connected to the drive motor 12 is provided.

Referring to Figure 2, the above-described fixed saw blade 13 is formed in a ring shape and the saw blade protrudes toward the rotating saw blade 14, and the rotating saw blade 14 is similarly formed in a ring shape and the saw blade toward the fixed saw blade It is formed protruding. And the outer circumference of the saw blade of the fixed saw blade (13) is in close contact with the inner circumference of the saw blade of the rotating saw blade (14), but the side of the saw blade that contacts when the rotating saw blade (14) is rotated is inclined like the blade of the scissors, so that the rotating saw blade (14) rotates. When the raw material introduced through the supply line 11 is finely pulverized.

That is, the fixed saw blade 13 and the rotating saw blade 14 are arranged so that the saw blades face each other, but the inner diameter of the fixed saw blade 13 is larger than the inner diameter of the rotating saw blade 14, and the saw blade of the rotating saw blade 14 is fixed. It is positioned to be connected to each other inside the saw blade (13). Therefore, when the rotating saw blade 14 is rotated by the drive of the driving motor 12, the saw blade of the rotating saw blade 14 continuously contacts the saw blade of the fixed saw blade 13, and the blade of the scissors cuts the paper. It is crushed finely.

At this time, the crushing size of the raw material pulverized in the rotary cavitation unit 10 is controlled by VDF (Variable Drive Frequency) that controls the rotational speed of the drive motor 12 connected to the rotary saw blade 14. There is no need for pretreatment to be cut to size. That is, when the raw material is input, the rotational speed of the drive motor 12 is made low to cut the raw material into an appropriate size, and after the raw material is cut to a certain extent, the rotational speed is gradually increased to a high speed so that the raw material is finely crushed. .

Meanwhile, due to the high-speed centrifugal force generated in the rotary cavitation when rotating the saw blade 14, the pulverized raw material expands and collapses due to the hydrodynamic cavitation generated by repeating narrowing and widening when the rotating saw blade 14 is rotated. The primary ingredient is extracted from the raw material by the force of action.

Next, one end of the first discharge line 20 is connected to one side of the above-described rotary cavitation unit 10, and the discharge line is a vortex cavitation unit 30, which will be described later, in which the pulverized and primary component extraction is completed. It plays a role to be discharged into the. Although not shown, an opening/closing valve is provided inside the first discharge line 20 so that the first discharge line 20 is closed during operation of the rotary cavitation unit 10 and then opened after the operation is completed. In addition, it is assumed that a high-pressure pump 21 is installed in the first discharge line 20 so that the treated material can flow at a high pressure to the vortex cavitation unit 30 to be described later.

Next, referring to FIG. 3, a vortex cavitation unit 30 is connected to the other end of the first discharge line 20 described above. The vortex cavitation part 30 passes through the cavitation generating space part 31 after the treatment material introduced into the inside through the first discharge line 20 is rotated by the vortex forming screw 32, and secondary component extraction is performed. It plays a role in making it happen.

In this vortex cavitation part 30, a first discharge line 20 is connected to one side of the treatment material, and a cavitation generating space 31 is formed therein, and a vortex forming screw is formed behind the cavitation generating space 31. (32) is provided.

The above-described cavitation generating space 31 is formed at the rear and is connected from the large space 31-1 through which the treatment material is introduced and moved through the first discharge line 20, and the large space 31-1. As the cross-sectional area is gradually reduced, the speed of the treated material is reduced and pressure is increased to cause cavitation to occur, and the cross-sectional reduction space is connected to the cross-sectional reduction space 31-2. The small space part 31-3 that maintains the speed and pressure of the treated material generated in the part 31-2 and the small space part 31-3 are connected, but the cross-sectional area is increased to reduce the cross-section space part 31- 2) is connected to the first cross-section enlargement space part 31-4 and the first cross-section enlargement space part 31-4 to rapidly expand the cavitation generated by passing through 2), but the first cross-section enlargement space part The cavitation rapidly expanded by (31-4) is re-contracted at the connection point of the first section-enhanced space section (31-4), and then finally collapsed as it expands secondarily. 5) are formed sequentially.

The above-described section reduced space part 31-2 serves to decrease the speed of the fluid and increase the pressure of the fluid by gradually decreasing the cross-sectional area according to the traveling direction of the treated material, and this section reduced space part ( The pressure difference is generated by 31-2) and cavitation in the form of water vapor bubbles is generated by internal friction.

The large space portion 31-1 formed at the rear of the section reduced space section 31-2 is a space communicating with the first discharge line 20 so that fluid can be provided to the section reduced space section 31-2. The small space portion 31-3 formed in front of the cross-sectional reduced space portion 31-2 and the reduced-section space portion 31-2 has a deceleration state and a pressure increase state of the fluid by the cross-sectional reduced space portion 31-2, which will be described later. It plays a role of maintaining up to the first cross-sectional enlargement space part 31-4. At this time, the cross-sectional reduced space portion 31-2 is formed in a conical shape, and the large space portion 31-1 and the small space portion 31-3 are formed in a cylindrical shape.

In addition, the first section-enhancing space part 31-4 primarily serves to rapidly expand the cavitation generated by passing through the section-reduction space part 31-2, and the diameter of the small space part 31-3 As it is formed in a cylindrical shape having a larger diameter than that, the velocity of the processing material is rapidly increased and the pressure of the fluid is rapidly decreased, thereby causing the cavitation to rapidly expand firstly.

In addition, the cavitation rapidly expanded by the first cross-sectional enlargement space 31-4 in the second cross-sectional enlargement space 31-5 contracted again at the connection point of the first cross-sectional enlargement space 31-4. It is formed in the shape of a truncated cone in which the cross-sectional area gradually increases from a smaller cross-sectional area than the first cross-sectional enlargement space portion 31-4 as the secondary expands and finally collapses.

Therefore, the treated material introduced into the large space portion 31-1 of the vortex cavitation portion 30 through the first discharge line 20 causes cavitation to flow through the reduced-section space portion 31-2, and the first cross-section After passing through the enlarged space part 31-4, it is firstly rapidly expanded due to the increase in flow velocity and pressure reduction, and then the first section increase space part 31-4 and the second section increase space part 31-5 are connected. After contraction due to the decrease in flow velocity and pressure increase due to the decrease in the cross-section of the point, it expands and collapses secondarily due to the increase in flow rate and pressure decrease due to the flow through the second section-enhanced space (31-5), resulting in considerable pressure and heat. Is generated, and the primary component extraction for the treated material is performed with the resulting action force.

On the other hand, the vortex forming screw 32 provided in the above-described large space part 31-1 allows a vortex to be formed without additional power, thereby inducing smooth mixing and emulsification of the components inside the treated material, and also by forming a vortex. It serves to increase the hydraulic cavitation force within the cavitation generating space 31. It is assumed that one or more of these vortex forming screws 32 are arranged in series in the large space part 31-1 according to the size of the vortex cavitation part 30.

In addition, a second discharge line 40 is connected to one side of the vortex cavitation unit 30 described above, and the second discharge line 40 serves to discharge the treated material from which the secondary component has been extracted. Like the above-described first discharge line 20, the second discharge line 40 is provided with an opening/closing valve therein, so that the second discharge line 40 is closed during operation of the vortex cavitation unit 30. Then open it after the operation is complete.
