Description

melting device

The present invention relates to a dissolving device configured to dissolve a gas in a liquid, and more particularly, to a dissolving device using a venturi device to dissolve a gas in a liquid.

Generally, a dissolved solution means a liquid in which a predetermined gas is dissolved. The dissolved gas may exist in a very small size, for example, a micro or nano size in the solution, that is, as micro bubbles or nano bubbles. Such a solution may have various new characteristics depending on the type and properties of a liquid as a solvent and a gas as a solute, and accordingly, it is used in various industrial fields such as agriculture, industry, and medicine. For example, water is typically used as a liquid solvent in the solution, and air, oxygen, and carbon dioxide may be used as gaseous solutes.

The dissolving solution is usually prepared by a dissolving device, and the dissolving device is configured to mix and dissolve a gas in a liquid to create a dissolving solution. Various devices can be applied for mixing and dissolving these gases, and among these, a venturi device capable of achieving high solubility is mainly applied to the dissolution device.

These venturi devices have been continuously improved to have more improved performance, and these improved venturi devices, for example, include an injector unit that receives liquid and gas from the outside and dissolves the gas in the liquid, and a bypass pipe connected to the injector unit can include The bypass pipe bypasses a part of the liquid to control the flow rate of the liquid supplied to the injector unit, and accordingly, the amount of dissolved gas, that is, the gas concentration of the dissolved solution can be adjusted.

However, even in such an improved venturi device, since the bypass pipe must be separately provided, the manufacturing process for manufacturing the venturi device becomes complicated and the manufacturing cost increases. In addition, there is a concern that at least one of liquid, gas, and dissolved solution may leak through a portion where the injector unit and the bypass pipe are connected. In addition, since the injector unit is designed to generate only a predetermined amount of the lysate, there is a problem that it cannot properly respond to changes in the required volume of the lysate.

Furthermore, the quality of the lysate can be evaluated by a number of factors, for example, the solubility of the gas, the size of the dissolved gas (i.e., the particle size of the bubbles), and the duration of the dissolved gas. may affect quality. Therefore, there is a continuous need for improvement of dissolution equipment to produce high quality dissolution solutions.

More specifically, the venturi device includes: a housing provided therein with a flow pipe through which the liquid or the dissolved solution selectively flows and a bypass pipe communicating with the flow pipe and selectively bypassing the liquid flowing through the flow pipe; an injector unit detachably inserted into the flow pipe and configured to receive the liquid and the gas and dissolve the gas in the liquid; and a valve member provided in the bypass pipe and configured to selectively open and close the bypass pipe.

In addition, the chamber is disposed in the duct to communicate with the flow path and may include a suction port connected to the flow path to introduce the liquid therein and an outlet connected to the flow path to discharge the introduced liquid into the flow path. can

Meanwhile, the melting device of the present invention may further include a magnetization device installed in the pipe and configured to magnetize the liquid flowing along the pipe.

Therefore, the melting device of the present invention has a simplified manufacturing process, can reduce manufacturing costs, and can respond to capacity changes.

In addition, the melting device according to the present invention includes a chamber connected to the venturi device and a nozzle built into the chamber, as well as various other additional devices. Thus, increased solubility or gas concentration as well as smaller size gas bubbles are made possible by the dissolution apparatus of the present invention, which can greatly increase the quality of the resulting dissolution solution.

As shown in FIGS. 1 and 2 , the melting device of the present invention may include a duct 100 and a venturi device 1 connected thereto.

First, the duct 100 may be basically configured to transport a liquid for generating a dissolution solution. In addition, the duct 100 may be configured to similarly convey the lysate produced in the venturi device 1 connected thereto. The duct 100 may include a flow path 100a configured to flow the liquid and the solution for the transfer thereof. The flow path 100a is formed inside the duct 100 and may extend along the duct 100 . The duct 100 may include one end (or upstream part) connected to a liquid supply source and the other end (or downstream part) connected to a predetermined external device. For example, the other end (or the downstream part) of the duct 100 may be connected to another device using the dissolution solution or a storage container for storing the dissolution solution. The duct 100 receives liquid from an external supply source through the flow path 100a, supplies the liquid to the venturi device 1 connected to the middle of the duct 100, and returns the dissolved solution generated from the venturi device 1 to the duct 100. It can be supplied and supplied to a designated external device through the flow path 100a.

More specifically, the duct 100 may include a first auxiliary duct 101 configured to supply liquid to the venturi device 1 . The first auxiliary duct 101 is connected to the duct 100, precisely its body and the venturi device 1, respectively. As shown in FIG. 2, the duct 100 is formed on its body and includes an outlet 101a communicating with its flow path 100a, and the first auxiliary duct 101 is connected to the outlet 101a. . Accordingly, the liquid flowing along the flow path 100a may flow through the outlet 101a and the first auxiliary duct 101 and be supplied to the venturi device 1 . Meanwhile, the duct 100 may include a second auxiliary duct 102 configured to receive the dissolving solution generated in the venturi device 1 . The second auxiliary duct 102 is connected to the body of the duct 100 and the venturi device 1, respectively. Referring to FIG. 2, the duct 100 is formed on its body and includes a suction port 102a communicating with the flow path 100a, and the second auxiliary duct 102 is connected to the suction port 102a. Therefore, the dissolved solution generated and discharged from the venturi device 1 can be supplied to the duct 100, more precisely, to the flow path 100a thereof by flowing through the second auxiliary duct 102 and the intake port 102a. The supplied dissolved solution may flow along the flow path 100a of the duct 100 and be provided to a designated external device. That is, by such

auxiliary ducts

101 and 102 , the liquid may bypass the flow path 100a of the duct 100 , be converted into a dissolved solution in the venturi device 1 , and return to the flow path 100a again.

Such ducts and

auxiliary ducts

100, 101, and 102 may be dedicated pipes for the dissolution device when the dissolution device is an independent device, that is, a separate device configured to form only the dissolution solution, and a processing system using the dissolution solution generated by the dissolution device. If part of, it may be part of such processing system piping.

Venturi device 1 may also be connected to duct 100 and configured to produce a solution, as described above. The venturi device 1 may be configured to receive liquid from the duct 100 to generate a dissolution solution and supply the generated dissolution solution to the duct 100 again.

Referring to FIGS. 3 to 6 in addition to FIGS. 1 and 2 previously referred to, the venturi device 1 according to an embodiment of the present invention includes a housing 10, an injector unit 20, a valve member 30, A stopper member 40 and a gas supply member 50 may be included.

The housing 10 may have a body that houses or permits the related parts of the venturi device 1, i.e., components 20-50, to be installed therein. The body of the housing 10 may be made of a solid member to have appropriate strength and rigidity for the stable embedding and installation of related parts. Thus, as shown, the housing 10 may be made of a solid body. Such a housing 10 has a flow pipe 11 and a flow pipe 11 in which at least one of liquid and gas dissolved liquid (ie, a solution) selectively flows inside the housing 10, precisely inside the solid body thereof, and It may include a bypass pipe 12 that communicates and selectively bypasses the liquid flowing through the flow pipe 11 .

The flow pipe 11 may be a pipe member installed or inserted into the body of the housing 10 to flow at least one of the liquid and the dissolved solution. In addition, as shown in FIG. 2, the flow pipe 11 is formed by processing the body of the solid housing 10, and thus may actually consist of a flow path integrally formed with the body of the housing 10. . The flow pipe 11 may extend in one direction.

More specifically, the flow tube 11 is provided at a position opposite to the supply end 11a and the supply end 11a, which is open to selectively supply liquid, and the discharge end 11b, which is open to discharge the dissolved solution. ) and a flow observation passage 11c provided between the supply end 11a and the discharge end 11b, through which at least one of the liquid and the dissolved solution selectively flows. As will be described later, an injector unit 20 is installed in the flow path 11c, and when gas is supplied to the injector unit 20, a dissolved solution is generated from the injector unit 20. Accordingly, only the liquid flows upstream of the injector unit 20 in the flow passage 11c, and the dissolved solution can flow downstream of the injector unit 20 by selective gas supply. Due to this configuration, at least one of the liquid and the dissolved solution selectively flows in the flow path portion 11c. In the case of the flow pipe 11, which is a flow path integrated with the body of the housing 10, the supply end 11a may be formed in one end of the solid housing 10 body, and the discharge end 11b may be formed in the housing 10 It may be formed in the other end of the body. In addition, the flow path portion 11c may be formed or extended while penetrating the solid body of the housing 10 between the supply end 11a and the discharge end 11b. This flow path 11c may be referred to as a first flow path to be distinguished from the flow path 12c of the bypass pipe 12 described later.

As well shown in FIG. 2, the first auxiliary duct 101 is connected to such a supply end 11a, and the liquid from the duct 100 passes through the first auxiliary duct 101 and the supply end 11a. It can be supplied to the flow pipe (11). In addition, the second auxiliary duct 102 is connected to the discharge end 11b, and the generated dissolved solution flows through the flow pipe 11, more precisely, from the flow path 11c to the discharge end 11b and the second auxiliary duct 102. It can be supplied to the duct 100 through.

Meanwhile, as shown in FIGS. 4 and 5 , the diameter D1 of the supply end 11a may be substantially the same as the diameter D2 of the discharge end 11b. The injector unit 20 can be inserted through this supply end 11a. Meanwhile, in order to prevent the injector unit 20 inserted through the supply end 11a from escaping to the discharge end 11b, a step 11d may be provided in the flow pipe passage 11c. This step 11d may be formed by protruding at least a part of the inner surface of the flow observation passage 11c. At this time, the step 11d comes into contact with the end of the injector unit 20 inserted through the supply end 11a to prevent the injector unit 20 from being separated from the discharge end 11b, and also prevents the injector unit 20 from escaping to the discharge end 11b. ) can also be prevented from being inserted through the discharge end 11b.

The bypass pipe 12 may be a pipe member installed or inserted into the body of the housing 10 to bypass the liquid flowing through the flow pipe 11 . In addition, as shown in FIG. 2, the bypass pipe 12 is formed by processing the body of the solid housing 10, and accordingly, it is actually made of a flow path integrally formed with the body of the housing 10. may be At this time, the bypass pipe 12 may be connected in communication with the flow pipe 11 through at least one connection part. More specifically, the bypass pipe 12 is connected to the inlet (or inlet) for introducing liquid into the bypass pipe 12 by being connected to the flow pipe 11 and the bypass pipe 12 by being connected to the flow pipe 11. An outlet (or outlet) for discharging the flowing liquid back into the flow pipe 11 may be included. In addition, the bypass pipe 12 may be spaced apart from each other by a predetermined distance in a direction perpendicular to the extension direction of the flow pipe 11 .

Specifically, the bypass pipe 12 includes an insertion end 12a opened to accommodate the valve member 30, a closed end 12b provided at a position opposite to the insertion end 12a and closed, and an insertion end 12a. ) and the closed end 12b, and may include a bypass tube passage 12c through which liquid selectively flows. In the case of the bypass pipe 12, which is a flow path integrated into the body of the housing 10, the insertion end 12a may be formed within one end of the solid housing 10 body. As shown, the insertion end 12a may be disposed adjacent to the inlet or inlet of the bypass pipe 12, and accordingly, the valve member 30 provided at the insertion end 12a facilitates the inflow of liquid. You can control it. In addition, the insertion end 12a may be formed of a channel extending from the inside of the bypass pipe 12, that is, from the flow path 12c to the outside of the body of the housing 10. That is, the insertion end 12a may be formed of a channel connecting the inside of the bypass pipe 12, that is, the flow path 12c and the outside of the housing 10 body. Accordingly, the insertion end 12a can communicate the flow path 12c with the outside of the body of the housing 10, and the flow path 12c as well as the insertion end 12a can communicate with the outside of the housing 10 body. can be opened to the outside. For this reason, the valve member 30 in the open insertion end 12a can be easily inserted and installed from the outside of the housing 10, and has access to the flow path 12c to open and close the bypass pipe 12. can do. Similar to the insertion end 12a, the closed end 12b may be formed in the other end of the body of the housing 10, but is not communicated with or open to the outside of the housing 10 to prevent liquid from flowing out. does not The closed end 12b may be disposed adjacent to the outlet or outlet of the bypass tube 12, as shown. In addition, the passage portion 12c may be formed or extended while penetrating the solid body of the housing 10 between the insertion end 12a and the closed end 12b. This flow path 12c may be referred to as a second flow path to be distinguished from the flow path 11c of the flow pipe 11 described above.

As described above, the flow pipe 11 and the bypass pipe 12 may be integrally formed within the housing 10 body so as to be disposed within the housing 10 body. That is, the flow pipe 11 and the bypass pipe 12 are formed as a kind of flow passages within the body of the solid housing 10, and thus can be integrated with the housing 10. Thus, in the present invention, the flow pipe 11 and the bypass pipe 12 can be formed as a single module sharing the same body as the housing 10 .

The injector unit 20 may dissolve the gas into the liquid by mixing the liquid and the gas. To this end, the injector unit 20 may be detachably inserted into the flow pipe 11 of the housing 10 . Such an injector unit 20 will be described in more detail below with reference to related drawings in addition to the previously referenced FIGS. 2 to 6 . FIG. 7 is a perspective view showing an injector unit of the venturi device included in the melting device of FIGS. 1 and 2 , and FIG. 8 is a cross-sectional view of the injector unit taken along line D-D in FIG. 7 .

Referring to FIGS. 7 and 8 , the injector unit 20 forms an external appearance, and is provided inside the main body 21 that is replaceably inserted into the flow pipe 11 and the main body 21, and gas and liquid are mixed. A venturi member 22 having a venturi passage 221 capable of flowing and having one end connected to the main body 21 and the other end connected to the venturi member 22, the circumferential direction of the venturi member 22 It may include a plurality of spray members 23 spaced apart along the.

The body 21 may include an O-ring insertion portion 211 in which at least a portion of an outer surface protrudes toward the inside of the body 21 in the radial direction. The O-ring insertion portion 211 may extend along the circumferential direction of the main body 21 and may be provided in plurality. In addition, the plurality of O-ring insertion parts 211 may be spaced apart at predetermined intervals along the longitudinal direction of the main body 21 . At this time, an O-ring member 213 may be inserted into the O-ring insertion part 211, and airtightness between the flow pipe 11 of the housing 10 and the main body 21 may be maintained by the O-ring member 213. . Here, if the terms for the direction are defined, the inner radial direction of the main body 21 means a direction from the inner surface of the main body 21 toward the center of the main body 21, and the circumferential direction of the main body 21 is the main body ( 21) means a direction of rotation along the outer circumferential surface, and the longitudinal direction of the main body 21 means the x-axis direction in FIG. 1 . At this time, when viewed from the side of the body 21, the circumferential direction of the body 21 may be any one of clockwise and counterclockwise directions, and unless otherwise specified, the directions are both positive and negative directions. cover

On the other hand, the main body 21 may include a protrusion 212 protruding inward in the radial direction of at least a portion of the outer surface of the main body 21 . Here, the degree of protrusion of the protruding part 212 radially inward of the main body 21 may be greater than the degree of protruding of the O-ring insertion part 211 to the inner side of the main body 21 in the radial direction. At this time, the protrusion 212 may extend along the circumferential direction of the main body 21 and may be provided between two adjacent O-ring insertion parts 211 in the longitudinal direction of the main body 21 . Accordingly, the injector unit 20, more precisely, the main body 21 may have a protruding portion 212 that protrudes radially inward from the outer periphery of the main body 21 to a predetermined depth and extends in the circumferential direction.

Meanwhile, the other end of the spray member 23 may be connected to the inner surface of the protrusion 212 in communication. As the protrusion 212 protrudes radially inward from the main body 21, the outer surface of the protrusion 212 and the inner surface of the flow pipe passage 11c are spaced apart to form a predetermined space 212a. can (see Figure 2). The space portion 212a may be used as a space in which gas supplied from the gas supply member 50 flows, and the gas flowing through the space portion 212a is spraying member 23 connected to the inner surface of the protruding portion 212. ) It can be supplied to the venturi member 22 through the other end. Therefore, the injector unit 20 is formed to continuously extend along the circumferential direction on the outer circumference of the main body 21 and includes a space 212a forming a space in which gas supplied from the outside of the venturi device 1 flows. can include

The venturi member 22 may serve to form a vortex of liquid supplied from the outside by using the venturi effect. To this end, the venturi member 22 may have a venturi passage 221 in which gas and liquid may be mixed and flowed.

Specifically, the venturi member 22 includes a first downwardly inclined portion 222 inclined downward from one end to the other end, a second downwardly inclined portion 223 downwardly inclined from the other end to one end, and a first downwardly inclined portion 223. A neck portion 224 connected between the portion 222 and the second downwardly inclined portion 223 may be included. Here, the cross-sectional area of the first downwardly inclined portion 222 may decrease from one end to the other end, and the cross-sectional area of the second downwardly inclined portion 223 may also decrease from the other end to one end. At this time, one end of the injection member 23 may be connected to the neck portion 224 in communication. As such, since the injection member 23 is connected in communication with the neck portion 224 where the flow rate increases, liquid and gas can be smoothly mixed in the venturi passage 221 . As an example, the liquid is introduced through the first downwardly inclined portion 222, mixed with the gas at the neck portion 224, and produced as a dissolved solution, and the produced dissolved solution passes through the second downwardly inclined portion 223 through a venturi. It can be discharged to the outside of the member 22 .

Meanwhile, the flow rate passing through the venturi passage 221 of the venturi member 22 may be determined according to the diameters of one end and the other end of the venturi member 22 . Since the conventional venturi member is coupled to the inside of the pipe, only the flow rate according to the predetermined diameter of the venturi member is digested, but the venturi member 22 according to an embodiment of the present invention is coupled to the inside of the main body 21, As the main body 21 is detachably coupled to the flow pipe 11, when it is necessary to respond to a change in flow rate, after selecting the main body 21 coupled with the venturi member 22 having a diameter suitable for the changed flow rate, By combining with (11), it is possible to respond to flow rate change differently from the prior art. That is, the amount of dissolving liquid produced, i.e., the capacity, of the venturi device 1 can be controlled by this replaceable venturi member 22.

The plurality of injection members 23 may transfer the gas provided from the gas supply member 50 to the venturi member 22 . In addition, the plurality of injection members 23 may increase a contact area between the liquid flowing through the venturi member 22 and the gas supplied from the gas supply member 50 .

To this end, the plurality of injection members 23 are located inside the main body 21 and may be installed between the space portion 212a and the venturi member 22 . In addition, the plurality of injection members 23 may be spaced apart from each other at a predetermined interval along the circumferential direction of the venturi member 22 . In addition, the injection members 23 may extend in a radial direction between the space portion 212a and the venturi member 22, and may be oriented in a direction perpendicular to the central axis of the venturi member 22. For example, each of the injection members 23 may be made of a 5-member member configured to inject the gas in the space 212a to the neck 224 of the venturi member 22 .

One end of each spray member 23 may be communicatively connected to the protrusion 212 of the body 21, and the other end of the spray bonsai 23 may be communicatively connected to the neck 224 of the venturi member 22. there is. In addition, the plurality of ejection members 23 are spaced apart along the circumferential direction of the venturi member 22, and the gas supplied from the gas supply member 50 is radially inside the venturi passage 221 of the venturi member 22, That is, it may be injected toward the inside of the neck portion 224 in the radial direction. That is, each injection member 23 has one end directly connected to the space 212a and the other end directly connected to the neck 224 inside the venturi member 22 having a relatively reduced cross-sectional area. , It may be configured to spray the gas flowing in the space portion 212a to the neck portion 224 of the venturi member.

Gas supplied to the injector unit 20 from the outside first enters the space 212a, which is a preliminary flow area. Since the space portion 212a continuously extends along the outer circumference of the main body 21 of the injector unit 20, the supplied gas flows while turning on the outer circumference of the main body 21 along the space portion 212a. . Therefore, the gas supplied by the generated rotational force can be advantageously accelerated by the space portion 212a to be primarily supplied to the inside of the venturi member 22, and is uniformly distributed outside the outer circumference of the venturi member 22. It can be. Subsequently, the accelerated and uniformly distributed gas is supplied to the inside of the venturi member 22 through the plurality of injection members 23, precisely to the neck portion 224, which is a reduced cross-sectional area thereof. Since the plurality of injection members 23 are spaced apart from each other along the circumferential direction of the venturi member 22, the gas flows through the injection members 23 throughout the inside of the neck 224 of the venturi member 22. can be sprayed across. Gas can be uniformly injected into the neck portion 224 of the venturi member 22 while being accelerated by the space portion 212a of the injector unit 20 and the injection members 23 . Accordingly, the liquid forming a vortex in the venturi passage 221 and the gas injected toward the inside of the venturi passage 221 in the radial direction collide with each other, so that the gas can be efficiently dissolved in the liquid. For this reason, according to the present invention, the gas can be uniformly mixed with the fluid in a large amount in the venturi member 22, and the overall performance of the melting device can be greatly improved.

The valve member 30 is provided in the bypass pipe 12 and may be configured to selectively allow liquid in the flow pipe 12 to flow from the flow pipe 12 to the bypass pipe 12 . For the selective flow of the liquid to the bypass pipe 12, the valve member 30 may be configured to selectively open the bypass pipe 12. Also, for selective opening, the valve member 30 may be movably installed or inserted into the body of the housing 10 .

More specifically, as described above, the insertion end 12a of the bypass pipe 12 is connected to the outside of the housing 10 body while being connected to the flow path 12c within the housing body 10, or is connected thereto. can be opened The valve member 30 is inserted into the insertion end 12a of the bypass pipe 12 from the outside of the housing 10, and can be configured to slide within the insertion end 12a. That is, the valve member 30 can be slidably inserted into the insertion end 12a. As described above, the insertion end 12a is a channel that continuously extends from the outside of the housing 10 body to the bypass pipe 12 inside the housing 10 body, precisely to its flow path 12c, so that the valve The member 30 is movable along this insertion end 12a. Therefore, while the valve member 30 moves along the insertion end 12a, it selectively opens the bypass pipe 12, that is, the flow passage 12c to communicate with the flow pipe 11, or does not communicate with the flow pipe 11. You can close it to avoid it.

2 and 11, when the valve member 30 moves toward the bypass pipe 12 (or flow path portion 12c) along the insertion end 12a (ie, the valve member 30) is completely inserted into the insertion end 12a), the end of the valve member 30 can reach into the bypass pipe 12 (or flow path 12c) and close it. As shown in FIG. 2 to control the movement or insertion of the valve member 30, a stopper is formed on the outer circumference of the valve member 30, and a stopper may be formed on the inner circumference of the insertion end 12a. . Accordingly, the valve member 30 can be inserted or moved until these stoppers are engaged with each other, and the valve member 30 can be configured to close the bypass pipe 12 when the stoppers are engaged with each other. In this way, when the bypass pipe 12 is closed by the valve member 30, the liquid in the flow passage portion 11c of the flow pipe 11 cannot be diverted to the flow passage portion 12c of the bypass pipe 12. . On the other hand, as shown in FIG. 12, from this closed position, the valve member 30 moves in the opposite direction along the insertion end 12a, that is, away from the bypass pipe 12 (or flow path portion 12c). When moved, the bypass pipe 12 is opened by the valve member 30, and at least a portion of the fluid in the flow passage 11c may be bypassed to the flow passage 12c of the bypass pipe. Due to this detour, the flow rate of the liquid supplied to the injector unit 20 is changed, and the change in flow rate results in a change in pressure inside the injector unit 20 . Therefore, as the pressure of the gas injected from the plurality of injection members 23 of the injector unit 20 changes, the amount of gas injected also changes, and the amount of gas dissolved in the liquid in the injector unit 20, that is, the gas of the dissolved solution. Concentration may vary. For this reason, the valve member 30 adjusts the amount of liquid and the liquid pressure supplied to the injector unit 20 by selectively opening and closing the bypass pipe 12 and thereby bypassing the liquid, thereby controlling the pressure and amount of gas supplied. It is possible to adjust the gas concentration (i.e., solubility) in the solution by this control.

In addition, since the valve member 30 is configured to slide along the insertion end 12a, the amount of movement of the valve member 30 can be easily adjusted. Therefore, the degree of opening of the bypass pipe 12 can be adjusted by adjusting the amount of movement of the valve member 30, and by adjusting the amount of liquid flow through the bypass pipe 12 according to the opening control, the injector unit 20 The gas concentration of the dissolved solution produced within can also be adjusted. As shown in FIGS. 2, 11 and 12, a part of the valve member 30, that is, its end may be configured to continuously protrude out of the body of the housing 10. Therefore, by using the exposed end, the operator manually moves the valve member 30 along the insertion end 12a, thereby easily controlling the opening and closing of the bypass pipe 12. Instead of such a manual operation, the valve member 30 may be operated using a predetermined driving mechanism.

The valve member 30 described above may be formed of, for example, a plug member movably inserted into the insertion end 12a, but this is only an example, and thus the spirit of the present invention is not limited thereto.

At this time, referring to FIG. 2 , the valve member 30 may include an O-ring insertion portion 31 in which at least a portion of an outer surface protrudes radially inward of the valve member 30 . The O-ring insertion portion 31 may extend along the circumferential direction of the valve member 30 . At this time, an O-ring member 32 may be inserted into the O-ring insertion portion 31, and airtightness between the bypass pipe 12 of the housing 10 and the valve member 30 is maintained by the O-ring member 32. It can be.

Meanwhile, in the present embodiment, the valve member 30 is coupled to the insertion end 12a of the bypass pipe 12 as an example, but this is for convenience of description. The idea of the invention is not limited. For example, a male thread is formed on at least a portion of the outer surface of the valve member 30, and a female thread is formed on at least a portion of the inner surface of the insertion end 12a, so that the valve member 30 and the insertion end 12a It is also possible that the is screwed together.

As shown in FIGS. 2 and 3 , the stopper member 40 allows the injector unit 20 inserted through the supply end 11a of the flow pipe 11 to escape through the supply end 11a of the flow pipe 11. can prevent it from happening.

To this end, the stopper member 40 may be selectively inserted into the housing 10 . At this time, at least a portion of the stopper member 40 may be inserted into the stopper member insertion hole 14 formed in the housing 10 .

At this time, the stopper member 40 may be provided in a columnar shape extending in one direction, for example. For example, the stopper member 40 may be inserted into the stopper member insertion hole 14 after the injector unit 20 is inserted through the supply end 11a of the flow pipe 11 . On the other hand, when replacement of the injector unit 20 is required, as the stopper member 40 inserted into the stopper member insertion hole 14 is first separated from the stopper member insertion hole 14, the inserted into the supply end 11a The injector unit 20 can be separated from the supply end 11a.

On the other hand, in the present embodiment, the case where the stopper member 40 is fitted in the stopper member insertion hole 14 of the housing 10 has been described as an example, but the spirit of the present invention is not limited thereto. . For example, a male thread is formed on at least a portion of an outer surface of the stopper member 40 and a female thread is formed on at least a portion of an inner surface of the stopper member insertion hole 14 so that the stopper member 40 is formed through the stopper member insertion hole It may be coupled to (14) by screwing.

The gas supply member 50 may selectively supply gas to the injector unit 20 from the outside. To this end, the gas supply member 50 may be provided to be connectable to the housing 10. At this time, referring to FIGS. 3 and 6, the end of the gas supply member 50 is provided in the housing 10 It may be inserted into the gas supply member insertion hole 13 .

Also, as shown in FIG. 2 , the gas supply member 50 may be connected in communication with the injection member 23 of the injector unit 20 . The external gas supplied through the gas supply member 50 flows in the space 212a formed spaced apart between the inner surface of the flow observation passage 11c and the outer surface of the protrusion 212, and the space 212a The gas flowing in may be supplied to the plurality of injection members 23 and injected into the venturi member 22 .

On the other hand, in addition to the venturi device 1 as described above, as shown in FIG. 2, the duct 100 may also be modified in various forms or include various additional devices, and these modifications and devices make it more A high quality lysate can be produced. The deformable structure and additional devices of the duct 100 will be described in more detail below.

First, the duct 100 may include a nozzle 110 disposed within its flow path 100a. The nozzle 110 may include a body made of a hollow tube extending to a predetermined length and suction and

discharge ports

111 and 112 respectively provided at both ends of the body. The outlet 112 has a smaller size than the inlet 111, and thus the liquid flowing into the inlet 111 and discharged to the outlet 112 has an increased flow rate. The nozzle 110, precisely its body, has a gradually decreasing diameter (or inner diameter) from the inlet 111 to the outlet 112, so that the liquid flows smoothly through the inlet 111 of the nozzle 110 without substantial resistance. It can flow out through the outlet 112 from.

As shown in FIG. 2, such a nozzle 110, that is, its body extends and is oriented along the flow path 100a of the duct 100, and its inlet 111 and outlet ( 112) is also disposed and oriented along the flow path 100a, i.e., its flow direction. Accordingly, the nozzle 110 causes the liquid to flow in the same direction as the flow direction of the flow path 100a, and is configured to accelerate the liquid during this flow. That is, the inlet 111 of the nozzle 110 sucks in the liquid in the same direction as the flow direction in the flow path 100a, and the outlet 112 of the nozzle 110 discharges the liquid in the same direction as the flow direction. Therefore, the nozzle 110 can be configured to accelerate the fluid in the flow path 100a in the same flow direction without any loss.

In addition, the duct 100 may include a chamber 120 of a predetermined size provided in its flow path 100a. The chamber 120 may be disposed at the outlet 112 of the nozzle 110 to receive the liquid discharged from the nozzle 110 . More specifically, the chamber 120 is disposed within the duct 100 to communicate with the flow path 110a and may be located downstream of the nozzle 110 . In addition, the chamber 120 communicates with at least the outlet 112 of the nozzle 110, and accordingly, the liquid discharged through the exposure 110 can be directly accommodated in the chamber 120. Furthermore, to stably accommodate the discharged liquid, the chamber 120 partially accommodates the tip of the nozzle 110 including the discharge port 112 therein, and thus the discharge port 112 is also included in the chamber 120. can be accommodated within. That is, the tip of the nozzle 110 including the outlet 112 may be partially inserted into the chamber 120 .

More specifically, the chamber 120 includes a suction port 121 connected to the flow path 100a to introduce liquid therein and connected to the flow path 100a to discharge the introduced liquid into the flow path 100a. It may include an outlet 122 to be. The inlet 121 and the outlet 122 of the chamber 121 are arranged and oriented along the flow path 100a, that is, its flow direction. Therefore, the chamber 120 is formed as a part of the flow path 100a, and basically, like the nozzle 110, it is configured to allow the liquid to flow in the same direction as the flow direction of the flow path 100a so as not to disturb the flow of the liquid. do. As shown, the nozzle 110 is actually tightly fitted into the inlet 121 of the chamber 121, and may be partially inserted into the inner space of the chamber 120 through the inlet 121. Therefore, as mentioned above, the outlet 112 of the nozzle 110 is disposed in the chamber 121 to discharge the liquid directly into the chamber 121 .

In addition, the chamber 120 may include an auxiliary inlet 123 configured to introduce the dissolution solution generated by communicating with the venturi device 1 into the chamber 120 . More specifically, the auxiliary inlet 123 is directly connected to the inlet 102a of the duct 100, and thus may communicate with the second auxiliary duct 102. Accordingly, the chamber 120 may be directly connected to the venturi device 1, precisely its discharge end 11b, through the auxiliary inlet 123, the inlet 102a, and the second auxiliary duct 102. For this reason, the chamber 120 can be supplied with the produced lysate from the venturi device 1 . That is, the venturi device 1 may be configured to discharge the generated lysate into the chamber 120 .

As described above, since the liquid accelerated by the nozzle 110 is primarily discharged into the chamber 120, due to the high flow rate of the discharged liquid, the chamber 120 is in a relatively low pressure state, that is, negative pressure. environment can be created. Therefore, the dissolved solution generated in the venturi device 1 due to this negative pressure environment can be more smoothly sucked into the chamber 120 through the second auxiliary duct 102, the suction port 102a, and the auxiliary suction port 123. . In practice, the flow rate of the lysate can be substantially increased by the negative pressure environment during such suction. The accelerated dissolving solution collides with the liquid accelerated by the nozzle 110 in the chamber 120 as well, and the gas in the dissolving solution can be split into smaller sizes by this collision. In addition, a large vortex is generated by such a collision, and the gas decomposed by the generated vortex can be better dissolved in the liquid. Therefore, by the configuration of the duct 100 described above, that is, the chamber 120 mixing the liquid supplied from the nozzle 110 and the dissolved liquid supplied from the venturi device 1, as well as the gas bubbles of smaller size, more A high quality lysate with a high amount of dissolved gas (i.e., increased solubility or gas concentration) can be produced. The dissolved solution additionally treated in this way may be supplied to an intended external device along the flow path 100a through the outlet 122 of the chamber 120 .

Furthermore, to further improve the quality of the solution, the venturi device 1 may be configured to discharge the solution to the side of the nozzle 110, as best seen in FIG. 2 . When the dissolved solution is discharged to the side of the nozzle 110, the dissolved solution collides with the side of the nozzle 110 in addition to the collision with the sprayed liquid. In addition, the collided solution naturally forms a rotational flow or a vortex while turning along the side of the nozzle 110 . Such additional collisions and vortices further promote the formation of small gas bubbles and an increase in solubility or gas concentration for the same reason as described above, and the quality of the dissolution solution can be further improved. As shown in FIG. 2 , the auxiliary inlet 123 of the chamber 120 may be disposed to face the side of the nozzle 110 so that the dissolved solution is discharged to the side of the nozzle 110 . Also, for the same purpose, the nozzle 110 extends long into the chamber 120 so that the discharge port 112 of the nozzle may be disposed beyond the auxiliary suction port 123 . This configuration allows the dissolved solution to be discharged to the side of the nozzle 110, and can ensure the aforementioned effect.

In addition, as shown in FIG. 2 , the pipe 100 may include an expansion pipe 130 provided in the flow path 100a. The expansion tube 130 is formed as a part of the flow path 100a and may be disposed downstream of the chamber 120 to communicate with the chamber 120 . More specifically, the expansion tube 130 includes a suction port 131 connected to the chamber 120 to introduce dissolved water in the chamber 120 therein and discharges the introduced dissolved water into the flow path 100a. It may include an outlet 132 connected to the flow path 100a to do so. The inlet 131 and the outlet 132 of the expansion pipe 130 are arranged and oriented along the flow path 100a, that is, its flow direction. Therefore, like the nozzle 110 and the chamber 120, the expander 130 basically flows the dissolved solution processed in the chamber 120 in the same direction as the flow direction of the flow path 100a so as not to disturb the flow of the liquid. It is configured to allow

In addition, the inlet 131 of the expansion pipe 130 is directly connected to the outlet 122 of the chamber 120, and at the same time is also configured to communicate with the outlet 112 of the nozzle 110 in the chamber 120. More specifically, the inlet 131 of the expansion tube 130 may be aligned with the outlet 112 of the nozzle 110 and the outlet 122 of the chamber 120 . Furthermore, the inlet 131 of the expansion pipe 130 may be arranged concentrically with the outlet 112 of the nozzle 110 and the outlet 122 of the chamber 120, that is, on a common central axis. Due to this arrangement, the lysate in the chamber 120 can smoothly flow into the flow path 100a directly through the expansion tube 130 without substantial resistance, that is, without loss. In addition, due to the gradually expanding structure, the flow rate of the dissolving solution in the expansion tube 130 is lowered, allowing sufficient time for the gas to be additionally dissolved in the liquid. Therefore, such a pipe expansion unit 130 can further improve the quality of the produced solution.

Furthermore, due to the configuration described above, the nozzle 110 and the expansion pipe 130 are fluidly connected to each other and can substantially form an additional venturi structure, using which additional gas dissolution can be performed. . More specifically, the pipe 100 is disposed adjacent to the outlet 112 of the nozzle 110 and may include an injection pipe 140 configured to discharge gas to the outlet 112 of the nozzle 110. can A supply pipe 141 may be connected to the pipe 100 to supply gas to the injection pipe 140 . For practically stable gas injection, the injection pipe 140 is disposed at the outlet 122 of the chamber 120 corresponding to the neck of the formed venturi structure and/or the inlet 131 of the expansion section 130 to gas can be injected. Gas may be additionally dissolved in the dissolving liquid by the sprayed gas, and the solubility and gas concentration of the dissolving liquid may be substantially improved.

In addition, the duct 100 may additionally include an agitator 150 configured to form a vortex in the liquid in the flow path 100a. The stirrer 150 is provided in the flow path 100a and may be disposed at the inlet 111 of the nozzle 110. The stirrer 150 may be implemented according to various mechanisms for forming a vortex, and may be formed of, for example, a blade, an impeller, or a spiral flow path. A vortex is already formed in the liquid supplied to the nozzle 110 by the agitator 150, and such a vortex may be formed when discharged. Therefore, in the chamber 120, the liquid can be more smoothly mixed with the dissolution solution.

On the other hand, the dissolution device may further include an additional device to improve the quality of the dissolution solution in addition to the configuration of the duct 100 described above. As an example, as shown in FIG. 2 , the melting device may further include a magnetization device 200 installed in the duct 100 to magnetize the liquid in the duct 100 . When a liquid is magnetized, radicals are formed therein, and the radicals can impart various additional useful properties to the liquid. Such a magnetization device 200 will be described in more detail in the following with reference to additionally related drawings in FIG. 2 .

FIG. 9 is an exploded perspective view and a partial cross-sectional view illustrating a magnetizer included in the dissolution device of FIG. 1 , and FIG. 10 is cross-sectional views showing examples of cross sections of the holder of FIG. 9 .

Referring to FIGS. 9 and 10 in addition to FIG. 2 , the magnetization device 200 is provided on the outer periphery of the duct 100 and may include a mounter 210 configured to surround the duct 100. there is. The mounter 210 functions as a platform for mounting other parts of the magnetizer 200 to be described later on the duct 100. More specifically, the mounter 210 may include a sleeve 210a mounted on the duct 100 while surrounding it, and flanges 210b provided at both ends of the sleeve 210a. The flange 210b may extend a predetermined length in a radial direction from both ends of the sleeve 210a.

In addition, the magnetization device 200 is installed on the mounter 210 and may include a plurality of holders 220 disposed at predetermined intervals along the circumferential direction of the mounter 210 . The holders 220 may be formed of a member in the form of a rod extending long, and may be actually installed on the flange 210b of the mounter 210a. More specifically, the flange 210b includes a plurality of seats 210c, and these seats 210c may be made of recesses or through holes. Accordingly, both ends of the holder 220 are fitted into the seat portion 210c of the flange 210b, and thus the holder 220 can be mounted on the mounter 210.

Furthermore, the magnetization device 200 may include a permanent magnet 230 disposed within each holder 220 . The permanent magnet 230 serves to magnetize the liquid in the duct 100 by actually forming a magnetic field. If the permanent magnet 230 protrudes to the outside of the holder 220, the volume of the magnetizer 200 increases, making installation and maintenance difficult. For this reason, the permanent magnet 230 may be embedded inside each of the holders so as not to protrude outward. As an example, the holder 220 may include through-holes 220a formed in a radial direction or a width direction, and the permanent magnet 230 may be embedded in the through-holes 220a so as not to protrude. In addition, the holder 220 may also be made of a strong magnetic material, and thus a stronger magnetic field may be formed.

In this case, generally as shown in FIG. 10 (a), the magnetic holder 220 may have a smooth outer surface. However, when the holder 220 has a polygonal cross section, as shown in FIGS. 10(b) and (c), it has more surfaces from which magnetic lines of force are emitted, and is advantageous for forming a strong magnetic field. For this reason, the holder 220 preferably has a polygonal cross section as shown in Figs. 10(b) and (c). As an example, FIG. 10( b ) shows a holder 220 having a pentagonal cross-section with five surfaces from which magnetic lines of force are emitted. In addition, FIG. 10(c) shows the holder 220 having a serrated cross section, and since it includes more surfaces than FIG. 10(c), it is advantageous to form a stronger magnetic field.

Such a magnetization device 200 may be provided not only to the duct 100 but also to the first and second

auxiliary ducts

101 and 102, and in this case, a higher quality solution may be produced.

Hereinafter, with reference to FIGS. 11 and 12, the action and effect of the dissolution device having the above configuration will be described.

Referring to FIG. 11 , the injector unit 20 is inserted through the supply end 11a of the flow pipe 11 provided inside the housing 10 . When the insertion of the injector unit 20 is completed, the stopper member 40 is inserted into the stopper member insertion hole 14 pre-installed in the housing 10 to prevent the injector unit 20 from being separated from the flow pipe 11, thereby opening the housing The installation of the injector unit 20 to (10) is completed. Next, the gas supply member 50 is connected to the gas supply member insertion hole 13 previously installed in the housing 10 . Finally, the duct 100 is connected to the housing 10, that is, the venturi device 1 using the

auxiliary ducts

101 and 102, and is ready to produce a solution.

Then, the liquid is supplied to the venturi device 1 from the outside through the supply end 11a of the flow pipe 11 using the duct 100 . At this time, since the valve member 30 is completely inserted into the insertion end 12a of the bypass pipe 12 provided inside the housing 10, liquid supplied from the outside is not bypassed to the bypass pipe 12. and can be supplied only through the flow pipe 11.

Meanwhile, the supplied liquid flows along the venturi passage 221 provided in the venturi member 22 of the injector unit 20 to form a vortex. At this time, the gas provided from the gas supply member 50 is supplied to the venturi passage 221 through the plurality of spray members 23 and is dissolved in the liquid while colliding with the vortex of the liquid. The dissolved liquid in the liquid in which the gas is dissolved may pass through the venturi flow path 221 and be discharged through the discharge end 11b of the flow pipe 11.

On the other hand, referring to FIG. 12, as the degree of insertion of the valve member 30 inserted into the insertion end 12a of the bypass pipe 12 is adjusted, the inlet of the bypass pipe 12 may be opened. , At least a portion of the liquid supplied from the outside may be bypassed to the bypass pipe 12 . Due to this bypass, the flow rate of the liquid supplied to the injector unit 20 is reduced, and the reduced flow rate also results in a decrease in pressure inside the injector unit 20 . Accordingly, the pressure of the gas injected from the plurality of injection members 23 of the injector unit 20 is relatively increased due to the decrease in internal pressure, and the amount of gas injected may also increase. Therefore, the amount of gas dissolved in the liquid in the injector unit 20, that is, the gas concentration of the dissolved solution can be increased. That is, by bypassing the fluid through the bypass pipe 12, the fluid amount and fluid pressure supplied to the injector unit 20 are reduced while the supplied gas pressure and gas amount are increased, and by this adjustment, a higher gas concentration ( That is, a solution having a solubility) can be produced.

The technical effects according to the configuration of the present invention described above are described in more detail as follows.

In the venturi device of the melting device, the flow pipe and the bypass pipe are integrally formed in the body of the housing. In addition, the valve member is movably installed in the body of the housing to selectively open the bypass pipe. According to this configuration, the claimed flow pipe and bypass pipe are formed as a kind of flow passages in the housing body, and the housing is formed as a single module incorporating flow passages required for gas and water mixing, such as the flow pipe and bypass pipe, into its body. . In addition, since the valve member together with the injector unit is disposed together with flow passages (i.e. flow pipe and bypass pipe) in the body of the housing, the venturi device is capable of integrating all required parts and flow passages into one module (i.e. housing). , more specifically, it can be configured as an all-in-one device integrated into one body.

In a conventional melting device, since required parts and passages are separated from each other and manufactured separately, the manufacturing process is complicated and high manufacturing cost is generated. On the other hand, in the venturi device of the melting device of the present invention, since the required parts and flow paths are integrated into one module (ie, housing), the intended device can be manufactured with relatively few processes and low cost. In particular, since flow channels such as the flow pipe and the bypass pipe can be integrally formed within the body of the housing by a single process such as casting and molding, manufacturing costs and processes can be greatly reduced. In addition, since the valve member is also built into the housing body and is configured to slide, it can have a simple and small size unlike conventional valves, thereby reducing manufacturing costs and processes.

In addition, when required parts and flow paths are manufactured separately from each other and connected, gas and water leakage may occur at the connection part, and an additional sealing structure or member of a considerable level is required to prevent such leakage. On the other hand, in the venturi device of the melting device of the present invention, the parts and the flow path are integrally formed in a single housing body or disposed together in the same body. Therefore, these parts and the connection parts of the passage are naturally sealed by the body of the housing without being exposed to the outside. Therefore, in the venturi device of the melting device of the present invention, leakage of gas and water and performance degradation due to this do not occur, and required performance can be stably exhibited.

In addition, the dissolving device includes various attachments provided to the duct and venturi device, and a higher quality dissolving solution can be produced by these attachments.

Although the embodiments of the present invention have been described as specific embodiments, this is merely an example, and the present invention is not limited thereto, and should be construed as having the widest scope according to the basic ideas disclosed herein. A person skilled in the art may implement a pattern of a shape not indicated by combining or substituting the disclosed embodiments, but this also does not depart from the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on this specification, and it is clear that such changes or modifications also fall within the scope of the present invention.
