Description

{Apparatus for mixing fluids}

The present invention relates to a fluid mixing device, and more particularly, to a fluid mixing device capable of mixing and releasing a plurality of fluids by using an inflow pressure of a fluid without including a separate stirrer.

The mixing of fluids is frequently performed in various industrial fields such as chemicals, medicines and foods, as well as in agriculture and construction and other living fields. This can be used.

One form used for mixing is to put a material to be mixed in one vessel and stir for a certain time with a stirrer connected to a motor. In this stirring, it is suitable to make the desired amount of mixture by adjusting the rotation speed or time of the stirrer, but it requires a separate stirring vessel and a stirring device, and it is made of a batch type, which is not suitable for the continuous process. have. In addition, since a separate stirrer is used for stirring, the cost of stirring increases.

On the other hand, if a plurality of materials to be mixed can be spontaneously mixed with each other, it is necessary to combine the flow of one material with the flow of another material so that one common space can flow and allow sufficient diffusion time between them. . In this case, however, it can take a lot of time, so it is first desired to provide an opportunity to mix physically enough to reduce the time of mixing and the overall process. However, a method such as placing a collision plate perpendicular to the flow direction on the path of the material flow is not easy to install, and may reduce the pressure in the material flow and prevent the smooth flow.

In addition, when the ejection of the mixture is aerosol-type nozzle injection, it may be possible to mix the material through the injection process. However, this is a special case in which ejection is a nozzle spray, and a high spray pressure is required to increase the mixing, and if the material is not sufficiently mixed in the flow to the nozzle, a mixture spray with a constant mixing ratio may be temporal. have.

An object of the present invention is to provide a fluid mixing device that can alleviate or solve the problems of the conventional mixing method described above in mixing a fluid.

The present invention can perform the mixing process without a vessel for a separate stirring or a stirring device that requires a separate power in the flow of the material to be mixed, can be naturally mixed in the continuous material flow process to obtain the result It is an object to provide a fluid mixing device.

It is an object of the present invention to provide a fluid mixing apparatus capable of continuously mixing various fluids and supplying the result immediately, regardless of the amount of fluid, at a relatively low cost and simple configuration.

The fluid mixing apparatus of the present invention for achieving the above object is provided with at least one unit fluid mixer, the unit fluid mixer is connected to the fluid inlet and the fluid inlet and has an outlet for discharging the fluid mixture In the fluid inlet, the inlet is formed in the peripheral wall, the inlet is coupled to the induction unit for inducing the fluid input direction to form a vortex in the interior space inflow fluid inclined in one side relative to the direction toward the center It is done.

In the present invention, the fluid inlet is made of a large diameter cylinder, the outlet portion is connected to the cylinder of the large diameter of the one end of the fluid inlet may be formed in the form of a funnel narrowing the diameter. In this case, the vortex is easily formed by the large diameter of the fluid inlet and the pressure of the inflowing fluid, so that the mixing can be facilitated.

In the present invention, the induction part formed in the inlet may be formed in the form of a branch protruding to the outside, the direction protruding outward in the induction part is bent in a clockwise or counterclockwise direction when looking at the fluid inlet from the outlet (In the clockwise direction, the fluid rotates counterclockwise and enters the fluid mixer interior through the fluid inlet.)

In the present invention, a protrusion may be installed on the inner surface of the wall forming the fluid mixer. This protrusion is intended to allow the fluids to be mixed more uniformly by forming a number of separate and fine irregular vortices, partly hitting the protrusions when they are swirled in a counterclockwise direction and are mixed in a vortex (rotating current). . However, it is preferable that the protrusion has a pointed triangular shape in which the projecting end is less hindered in the flow of the vortex flowing in the fluid mixer as a whole. In this case, the unit fluid mixer may be installed so that the fluid inlet and the other part (eg, the discharge part) can be separated and combined so as to easily form the protrusion on the inner surface of the wall.

In the present invention, the fluid inlet of the unit fluid mixer may be in a form in which other fluids may be introduced in an open form opposite to the outlet, or may be in a closed form. In the open form, it may simply be an open form, such as one end of a pipe, or may be closed in its entirety, partially open, or entirely closed, through which a separate narrow diameter pipe passes, and a narrow diameter through The piping of may have a plurality of holes in the wall inside the unit fluid mixer.

 In the present invention, when one end of the fluid inlet of the unit fluid mixer is open, the outlet of the other unit fluid mixer may be connected to the open part, and the outlet of the other unit fluid mixer may be connected to the inlet of the unit fluid mixer. In addition, a separate branch pipe is connected to an outlet of the unit fluid mixer, and branched branches of each branch pipe are connected to an inlet port of another unit fluid mixer to increase the degree of mixing while repeatedly forming vortices in the plurality of unit mixers. Can be.

In the present invention, a venturi structure in which the fluid path is narrowed and then widened again may be installed at the outlet of the unit fluid mixer.

According to the present invention, in the flow of the material (fluid) to be mixed, the mixing process may be performed without a separate stirring vessel or a stirring device requiring a separate power, and the mixing is naturally performed in a continuous material flow process. You will get the result.

According to the present invention, a relatively low cost and a simple configuration can continuously mix various fluids and supply the result immediately regardless of the amount of fluid.

Hereinafter, the fluid mixing apparatus of the present invention will be described in more detail with reference to the accompanying drawings.

1 to 2, the unit fluid mixer includes a fluid inlet 110 and an outlet 120 connected to the fluid inlet and through which the fluid mixture is discharged. The fluid inlet 110 has a cylindrical shape with a large diameter, and the outlet 120 is connected to a cylinder having a large diameter of the fluid inlet 110 at one end thereof, while the outlet 121 at the opposite end thereof has a diameter. This narrowing funnel is formed.

Eight inlets are formed in the peripheral wall of the fluid inlet 110, and the branches protrude in each of the inlets so as to be deflected in a clockwise direction outward when viewed from above. The protruding branches are formed to be inclined in one piece on the basis of the direction toward the rotationally symmetrical central axis of the cylinder forming the fluid inlet at the inlet formation position. Therefore, these branches form an induction part 119 which guides the fluid input direction to form a flow in which fluid flows and rotates along the circumference of the cylinder in the inner space. Of course, the pressure of the fluid flowing through each inlet and the cross-sectional area of the inlet may be varied depending on the characteristics of the mixed fluid and the composition of the mixture. For example, when the amount of fluid flowing through the inlet is different, the cross-sectional area of the inlet may be different to match the inlet pressure, and conversely, the pressure at the inlet may be different for each fluid while maintaining the same inlet cross-sectional area. However, the pressure at each inlet must be greater than the pressure at the outlet of the outlet and the unit fluid mixer to prevent backflow.

In the present embodiment having the above configuration, when the pressure of the fluid flowing into the inlet through the induction part 119 rotates the mixed fluid in the space of the fluid mixer, due to the large diameter of the cylinder forming the fluid inlet 110, Torque is increased even at the same inlet pressure as compared with the case where the diameter of the fluid inlet and the outlet is the same, so that vortices can be easily formed and mixing of the fluids can be facilitated.

3 and 4, the configuration of the fluid inlet 110 may be described in more detail. Eight inlets 111 are formed in the cylindrical wall 116 constituting the fluid inlet 110. The inlet 111 has an ellipse corresponding to an ellipse formed when the pipe branch constituting the induction part 119 is cut obliquely.

One end of the fluid inlet 110 (lower end in the drawing) may be completely clogged or fully open, but in this embodiment, the opening 117 at the center of the wall is closed through a single through pipe 115 in a state where most of it is blocked by the wall. ) Penetrates and protrudes upward. As can be seen in FIG. 3, the lower end of the through pipe 115 is integrated with the opening 117 formed in the lower wall of the fluid inlet 110, and the upper end is blocked, and the wall of the through pipe 115 has a plurality of holes 1151. ) Is formed.

Therefore, when a separate fluid input line is coupled to the bottom of the through pipe 115, the fluid flowing through the fluid and the fluid flowing through the inlet 111 of the fluid inlet may be mixed with each other. The fluid flowing through the through pipe 115 may be directed upward in a state in which the blocked top is pierced to directly face the outlet of the discharge portion, but the hole 1151 is formed only in the wall of the through pipe 115. Therefore, the fluid introduced through the fluid inlet line is prevented from proceeding immediately in the direction of the outlet, and forms a vortex with the fluid flowing from the inlet 111 to have a lot of opportunities to be mixed before being discharged to the outlet.

At the bottom of the through-pipe 115, a large amount of fluid serving as a solvent in the mixture may be introduced, and a relatively small amount of fluid serving as a solute may be introduced into the inlet 111.

FIG. 5 illustrates that a plurality of fins 113 protrude from the inner surface of the wall 116 of the fluid inlet 110 as shown in FIG. 4. The fin 113 is installed to make the mixing of the fluid better by generating fine vortices in the total rotational flow when the fluids introduced in the unit fluid mixer together form the rotational flow.

Here, the pin 113 forms a triangle, and one protruding end thereof corresponds to one corner of the triangle. This is to prevent the fin 113 from causing partial vortex, which severely disturbs the progress of the entire fluid and rather prevents mixing between the fluids.

The protruding edge angle, size, and number of the triangular pins 113 may be designed differently depending on characteristics such as the degree of mixing required or the viscosity of the fluid.

6 and 7, the outer shape of the outlet portion 120 coupled with the open portion of the fluid inlet form a funnel as a whole, so that the diameter of the connecting portion 127 connected to the fluid inlet is large and opposite to the outlet ( The diameter of 121) is small. Similar to the triangular fin 113 formed on the inner surface of the fluid inlet of FIG. 5, the triangular fin 123 is protruded on the inner surface of the wall of the outlet 120.

In order to facilitate the installation of the fins 113 and 123 for partial vortex formation on the inner wall of the unit fluid mixer as shown in FIGS. 5 to 6, the fluid inlet 110 and the outlet 120 are separately formed, and then It is preferable to form a fluid mixer by coupling the fluid inlet and the outlet to each other through coupling means such as screwing means formed in the connecting portion connected to each other. In this case, however, the sealing strength of the coupling means may be determined so that the fluid introduced into the fluid inlet 110 and the outlet 120 are not leaked to the combined portion of the fluid introduced therein. In addition, when the coupling of the fluid inlet and the outlet is detachable, it is convenient to prepare a plurality of fluid inlets different in number of inlets and to change the number of inlets by changing the fluid inlet if necessary.

Referring to FIG. 7, a venturi structure 125 is provided near the discharge port at the upper end of the discharge part to narrow the tube diameter and widen it. Although the venturi structure 125 has a portion that affects the mixing of the inflow, it may serve to control the pressure inside the unit fluid mixer and the discharge pressure at the outlet 121. The venturi structure 125 may also be considered to have an extreme shape such as a spray nozzle.

In addition, the fluid constituting the mixture may be of various types, the internal pressure may be involved in the flow rate and discharge of the fluid, the mixing process may affect the degree of mixing. In particular, when at least some of the mixture is gaseous or all gaseous, the venturi structure and internal pressure can have a significant effect on the mixing state and mixing state of the resulting mixture by varying the diffusion rate, solubility in the liquid.

In FIG. 8, four unit fluid mixers as shown in FIG. 1 are connected in series. The outlet 221 of the lower unit fluid mixer 200 is connected to an opening (or lower end of the through pipe) formed at the lower end of the fluid inlet 110 of the upper unit fluid mixer 100. Since different fluids can be introduced and mixed through the inlet at the fluid inlet of the unit fluid mixer at each stage, the fluids to be mixed first should be connected to the inlet of the lower unit fluid mixer, if the order of mixing is necessary. The fluids to be mixed later are connected to the inlet of the upper unit fluid mixer for mixing.

Although not separately illustrated, unlike in FIG. 9, the outlet of the lower unit fluid mixer is branched into a plurality of branches through a branch pipe, and each branched branch is connected to an inlet formed at the fluid inlet of the upper unit fluid mixer. The method may also be used. This case is suitable for the purpose of mixing the fluid mixed in the lower unit fluid mixer once more through the upper unit fluid mixer, rather than adding a separate fluid in the upper unit fluid mixer to make a sufficiently well mixed state.

In FIG. 9, the three outlets 421 of the unit fluid mixer 400 are connected to the inlets 319 of the other unit fluid mixer 300 at the upper part and mixed, and the resultant mixture of the unit fluid mixer 300 of the upper part fluid mixer 300 is mixed. The entire fluid mixing device is configured to be discharged through the outlet.

As shown in FIGS. 8 and 9, the inlet of each fluid mixer may be formed in an appropriate number in a configuration in which a plurality of unit fluid mixers are combined to form an entire fluid mixing device or in a configuration in which the fluid mixing device is formed only by the unit fluid mixer. In addition, with respect to each inlet, it is possible to install a valve in the induction coupled to the inlet, or a valve in the pipe coupled to the inlet. Then, it is possible to control and control the flow of fluids through the valve, so that the fluid mixer can be used without any problem even if the number of fluids to be mixed for mixing and the number of inlets of the unit fluid mixer are different.

Therefore, the fluid frequently used for mixing can be pre-connected to the inlet of the fluid mixer in advance, and the valves can be interrupted as necessary to produce and use the desired mixture with only the kind of fluid required at that time.

In this case, one of the through pipes or inlets can be connected to a fluid capable of washing or purging the interior of the unit fluid mixer, thereby cleaning the interior of the fluid mixer in the midst of changing the mixture, leaving the residues of the new mixture and the old mixture to be used. This can prevent problems caused by mixing.

Various fluids with different viscosities may be applied as the fluid to be mixed in the present invention, and a mixture of gas and liquid, liquid and liquid, and gas and gas may be considered. (Solids can only be considered in the form of fluids that are mixed or dispersed in other fluids in a fine powder state.)

This mixing can be done regardless of subsequent results. For example, a chemical reaction may be performed simultaneously with the mixing, or a case where a simple physical mixing is performed may be included, and the physical mixing may also include homogeneous mixing, heterogeneous mixing, and dispersion.

In the case of gas and liquid mixing, it is preferable to include the gas in the mixture in a fine bubble state, but since there is no separate power, in this case, the inlet pressure of the fluid is increased, and the diameter of the fluid inlet part is increased, contributing to the generation of vortices. It is desirable to increase the torque. In addition, it is desirable to increase the internal pressure of the fluid mixer itself by reducing the size of the neck of the venturi structure of the outlet portion or the size of the outlet itself. As the internal pressure increases, the degree of mixing may be greatly improved by increasing the solubility in the gas having a general solubility except when the solubility of the gas in the liquid is very high.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims. .
