Fluid Mixer

The present invention relates to a fluid mixing device, and more particularly to a fluid mixing device capable of effectively mixing fluids without a separate power.

Processes such as water and sewage treatment or chemical manufacturing generally include mixing different types of fluids, and the result of the process varies depending on how evenly different types of fluids are mixed.

The 'fluid mixing device and inspection system having the same' of Patent No. 10-1364639 is one of the related arts for mixing different types of fluids, and the mixing pipe 120 is bent with respect to the inlet pipe 110. It is formed so that the fluid is mixed by generating a flow rate difference between the fluid by the difference in curvature of the flow path at the bent portion.

However, the prior art has a problem that the size of the device is increased while forming the bent portion, the efficiency of mixing is also not high.

In another conventional art, 'Pharmaceutical rapid admixture using turbulent flow of fluid,' Patent No. 10-1558822 changes the diameter of a tube through which fluid moves and mixes the fluid by placing a rotor blade 224 in the tube.

Rotating blades can effectively mix the fluid in the tube while rotating, but because of the need for a separate power source to rotate the rotary blades can be economical and there is a problem that it is difficult to manage the rotary blades.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of the fluid mixing device 1 according to the present invention, and FIG. 2 is a cross sectional view of a combination of the body fluid mixing device 1 according to the present invention.

The fluid mixing apparatus 1 according to the present invention largely includes a main tube 10 and a mixing unit 20.

The main tube 10 is a tube through which different fluids to be mixed flow in one direction, and are generally formed in a one-shaped shape so that different fluids can be introduced into the main tube 10 through a separate inlet. Two or more inlets may be provided. For example, the main building 10 may be formed of a 'ㅗ' type or 'Y' type and may have two inlets, or may have three inlets.

The mixing unit 20 is disposed inside the main tube 10, and includes a flow path through which the fluid introduced into the main tube 10 passes. The flow path is formed in a shape that is switched to another direction and then converted to one direction again. The main pipe 10 serves to mix different fluids by converting the fluid flowing in one direction to another direction and then back to one direction.

As such, since the mixing unit 20 is disposed in the main pipe 10, a separate additional space is not required to mix different fluids, and strong vortices occur in the fluid since the flow of the fluid is rapidly changed two times. It is possible to effectively mix different fluids. Since this effect is caused by the shape of the mixing unit 20, it can be exerted without a separate power source for mixing the fluid.

The mixing unit 20 may form a first switching space S1 and a second switching space S2 included in the flow path in the main building 10.

The first switching space (S1) is introduced from the inlet of the main pipe 10 to discharge the fluid flowing in one direction in another direction, the second switching space (S2) is introduced from the first switching space (S1) The fluid flowing in the direction is diverted to one direction again and discharged.

The fluid passing through each of the conversion spaces formed can be surely redirected in the flow direction.

More specifically, the mixing unit 20 may include a center plate 21, a conversion pipe 22, and a conversion chamber 23.

The central plate 21 has the same size as the cross section of the main building 10 and is disposed parallel to the cross section of the main building 10. The center plate 21 is formed with a center hole 21a, a discharge hole 21b and an inlet hole 21c. The center hole 21a is formed at the center of the center plate 21, and a plurality of discharge holes 21b are formed along the virtual first closed figure f1 surrounding the center hole 21a. In addition, a plurality of inflow holes 21c are formed along the virtual second closed figure f2 surrounding the first closed figure f1. The center hole 21a, the first closed figure f1 and the second closed figure f2 may be formed in a circular shape, for example. That is, the center hole 21a, the first closed figure f1 and the second closed figure f2 are arranged to form concentric circles, and each of the plurality of discharge holes 21b is equally spaced from the circumference of the center hole 21a. Each of the plurality of inflow holes 21c has the same distance from the circumference of the center hole 21a, but the distance between each of the discharge holes 21b and the center hole 21a is the inflow hole 21c and the center hole 21a. It is formed smaller than the space between.

The conversion tube 22 is formed in a tubular shape in which one end portion and the other end portion have different diameters, such as a tapered tube, for example, and one end portion having a relatively small diameter has a center hole (one of the center plates 21). The other end which is joined to the circumferential part of 21a) and whose diameter is relatively large is joined to the inner side surface of the main tube 10. Accordingly, one side of the central plate 21 is formed with a first switching space S1 partitioned by one surface of the central plate 21, an outer surface of the switching tube 22, and an inner surface of the main tube 10. The fluid introduced into the first switching space S1 through the inlet hole 21c hits the inner side surface of the main tube 10 and the outer side surface of the switching tube 22 so that the flow direction is changed and through the discharge hole 21b. Discharged.

The conversion chamber 23 is formed in a container shape having an inlet on one side, and is disposed such that the inlet portion faces the center plate 21 on the other side of the center plate 21. The inlet portion edge of the switching chamber 23 is joined to the position between the first closed figure f1 and the second closed figure f2 of the other side of the center plate 21 to the second switching space toward the other side of the center plate 21. (S2) is formed. The fluid discharged through the discharge hole 21b in the first switching space S1 flows into the second switching space S2 and hits the inner surface of the switching chamber 23 to change the direction of flow, and then the center hole 21a. Is discharged through). The fluid discharged from the second switching space S2 passes through the internal space of the switching pipe 22 and leaves the mixing unit 20.

The mixing unit 20 may further include a guide tube 24.

The guide tube 24 has a short tube shape and is disposed to have a shape protruding along the circumference of the center hole 21a from the other surface of the center plate 21. The guide tube 24 prevents the fluid introduced into the second switching space S2 through the discharge hole 21b to be immediately discharged through the center hole 21a, thereby preventing the fluid in the second switching space S2. It is possible to make the change of direction more rapidly.

As the guide tube 24 is disposed in the second switch space S2, the second guide tube 25 is disposed in the first switch space S1 as shown in FIG. 3. The second guide tube 25 has a short tubular shape and is disposed to have a shape that protrudes at a position between the first closed figure f1 and the second closed figure f2 of one surface of the center plate 21. The second guide tube 25 prevents the fluid introduced into the first switching space S1 through the inlet hole 21c from being immediately discharged through the outlet hole 21b.

The switch tube 22 may be formed in a tapered tube shape as described above.

In this case, the first switching space S1 has a triangular shape on the longitudinal section of the mixing unit 20. Accordingly, the fluid in the first switching space can be rapidly diverted at the pointed corners of the triangle, and the fluid after the diverting is discharged along the side of the triangle formed by the outer surface of the switching tube 22. It may be guided to 21b.

The conversion tube 22 may be formed in a tapered tube shape by continuously changing the diameter, but if the diameter of one end is equal to the diameter of the center hole 21a and the diameter of the other end is equal to the inner diameter of the main tube 10, the diameter is equal to. It may change in stages. That is, the wall surface of the switching pipe 22 on the longitudinal section of the mixing unit 20 may be formed in a step shape.

When the switch pipe 22 has a tapered pipe shape, the tapered angle of the switch pipe 22 can be determined by the type of fluid. That is, the tapered angle of the switching pipe 22 can be adjusted according to whether or not different fluids are well mixed with each other.

When the tapered angle of the switch pipe 22 is adjusted, the size of the first switch space S1 and the angle formed by the wall of the switch pipe 22 with respect to the inner surface of the main pipe 10 are adjusted to adjust the first switch space ( The efficiency of fluid mixing can be adjusted within S1). In other words, when different fluids do not mix well due to hydrophilicity and hydrophobicity, respectively, the tapered portion of the switching pipe 22 is reduced so that the angle between the inner surface of the main pipe 10 and the wall surface of the switching pipe 22 becomes small. By adjusting the angle, the efficiency of fluid mixing is increased, and when the different fluids are all mixed well for reasons such as hydrophilicity, the angle between the inner surface of the main tube 10 and the wall surface of the switching tube 22 is increased. By adjusting the tapered angle of 22, the mixing unit 20 does not exert more fluid mixing efficiency than necessary.

The switching chamber 23 may be formed in a conical shape.

In this case, the fluid introduced into the second switching space (S2) is rapidly redirected at the pointed top of the cone can increase the efficiency of the fluid mixing.

Alternatively, the switching chamber 23 may be made of a hemispherical shape or a cube.

It is preferable that irregularities are formed on the surface of the mixing unit 20.

Unevenness causes turbulence to occur more effectively in the fluid, thereby increasing the efficiency of fluid mixing.

The mixing unit 20 may be detachably formed with respect to the main tube 10.

The fluid mixed by the fluid mixing device may include foreign matters and these foreign matters may be accumulated in the mixing unit 20. If the mixing unit 20 is detachable with respect to the main building 10, the mixing unit (in the main building 10) may be used. 20) to separate and wash the mixing unit 20, and then combine the mixing unit 20 to the main pipe 10 can be used for the fluid mixing device.

For example, as illustrated in FIG. 4, threads t1 engaged with each other are formed on the inner surface of the main tube 10 and the outer surface of the switching tube 22 of the mixing unit 20 to form the mixing unit 20. It can be attached to and detached from the main building 10.

The switching chamber 23 may be detachably formed with respect to the center plate 21.

In this case, when the switching chamber 23 is separated from the center plate 21, the second switching space S2 may be opened, thereby making it easier to wash the mixing unit 20.

The switching chamber 23 and the center plate 21 can also be attached and detached by forming a thread t2 engaged with each other on the outer surface of the switching chamber 23 and the other side of the center plate 21.

As shown in FIG. 5, the fluid mixing apparatus according to the present invention may include a plurality of mixing units 20.

The plurality of mixing units 20 are disposed along the longitudinal direction of the main tube 10, and in this case, the fluid may be more evenly mixed while rapidly changing the direction each time it passes through the mixing unit 20.

The number of mixing units 20 disposed in the main tube 10 may be adjusted according to whether or not different fluids have good mixing properties with each other. That is, when the different fluids are well mixed with each other, it is not necessary to arrange a plurality of mixing units 20 in the main pipe 10, but when the different fluids are not well mixed with each other in the main pipe 10 It may be desirable to arrange several mixing units 20.

In the fluid mixing apparatus according to the present invention, the main pipe 10 includes a plurality of unit pipes 11 that are longitudinally connectable as shown in FIG. 6, and each of the unit pipes 11 includes a mixing unit 20. This can be arranged.

In this case, it is possible to adjust the mixing efficiency of the fluid mixing device according to the present invention by adjusting the number of unit pipes 11 forming the main pipe 10.

One end inner side surface of the unit pipe 11 and the other end outer surface is formed with a thread (t3) of the interlocking shape can be connected to the unit pipe (11). Alternatively, flanges may be formed at both ends of the unit pipe 11 to couple the flanges of the adjacent unit pipes 11 with bolts and nuts.

The scope of the present invention is not limited to the above-described embodiment, but may be embodied in various forms of embodiments within the scope of the appended claims. Without departing from the gist of the invention claimed in the claims, it is intended that any person skilled in the art to which the present invention pertains falls within the scope of the claims described in the present invention to various extents which can be modified.
