DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixing apparatus for mixing a plurality of types of liquids continuously and efficiently without fail.

[0002]

2. Description of the Related Art Conventional mixers for mixing a plurality of liquids are:
There has been a structure in which a fluid is mechanically stirred or a baffle is provided in the middle of a passage for flowing the liquid, and the flow of the liquid is stirred by the baffle to mix.

[0003]

The conventional mixer, however, draws air during stirring in any case,
When air enters, the mixed liquid separates immediately,
There is a problem that a perfect mixture cannot be produced. Also, when the liquid to be mixed is food, it is necessary to frequently disassemble, clean, and assemble the mixer.
There is a problem that it takes time and effort to disassemble, clean and assemble.

It is an object of the present invention to provide a mixing apparatus which can produce a completely mixed liquid without mixing of air and which can be easily disassembled, cleaned and assembled.

[0005]

In order to solve the above-mentioned problems, a first aspect of the present invention is to inject a plurality of different types of liquids into an inside of a cylindrical body from an inlet at one end, and to inject another liquid into the cylindrical body. A device for taking out the mixed liquid from the outlet on the side, between the inlet and the outlet in the cylindrical main body, the same passage forming member that forms a passage having a different cross-sectional area between the opposing surfaces is stacked and stored, In a mixing apparatus in which a plurality of liquids pass through the passage while changing the flow velocity and pressure thereof, and mix by repeating branching and joining of the flow, the passage forming member has protrusions for forming a passage on both surfaces. By adopting a configuration in which the passage forming members are vertically overlapped and the projections are fitted together to form passages having different cross-sectional areas between the projections, and the liquid flowing in the passages repeats the branching and joining. is there.

According to a second aspect of the present invention, in the first aspect of the present invention, the passage forming member is provided with a through hole at a position near the outer peripheral portion for communicating the passage formed on both surfaces, and the passage formed on both surfaces. When the passage forming members are vertically overlapped so that the through holes are located on opposite sides of each other, the formation protrusions are provided in a pattern in which they are fitted to each other to form passages having different cross-sectional areas. Things.

[0007]

When a large number of passages are stored in the cylindrical body in a stacked manner, the upper and lower passage forming members are fitted with each other on both surfaces to form passages having different cross-sectional shapes, and the entrance of the cylindrical body is formed. When a plurality of different types of liquids are injected from the container, the liquids change their flow velocity and pressure while passing through the passage, and are completely mixed by effectively repeating the branching and joining of the liquids. By passing through the sealed passage inside, the mixed liquid without separation can be taken out from the outlet of the container body without air being mixed.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the cylindrical main body 1 is formed by stacking an upper lid 3 on the upper end of a cylindrical body 2 and a lower lid 4 on a lower end thereof, and fastening the upper lid 3 and the lower lid 4 with a plurality of bolts 5. A large number of passage forming members 6 are accommodated in the cylindrical main body 1 in an overlapping state, and the upper lid 3 has a liquid inlet 7 and the lower lid 4 has an outlet 8.
Are provided.

The passage forming member 6 is provided with projections 10 and 11 for forming passages on both surfaces of a branch 9 having an inner diameter which just fits into the cylindrical body 2 and further has a passage penetrating both surfaces at a position closer to the outer periphery. The hole 12 is provided.

The projections 10 and 11 provided on both sides of the disk 9 are
Flat rectangular objects are arranged in series in the length direction at a constant interval, and a plurality of those arranged in series are arranged in parallel.

The projections 10 and 11 provided on both sides of the disk 9
As shown in FIG. 1, when the passage forming members 6 and 6 are vertically overlapped so that the through holes 12 are located on opposite sides, as shown in FIG. The projections 10 are set so as to be aligned with each other and to be displaced by a half pitch with respect to the mating projection in the serial direction.
The passages 13 having different cross-sectional areas are formed between the first and second protrusions 11 and between the projections in series.

As shown in FIG. 2, the passages 13 having different cross-sectional areas communicate with each other so as to be straight at right angles, as shown in FIG. It is a combination to do.

Accordingly, when the passage forming members 6 having the same structure are successively stacked inside the cylindrical body 2 so that the same surface faces upward and the arrangement of the through holes 12 is reversed on both sides, the passage forming members 6 A passage 13 having a portion having a different cross-sectional area between the projections 10 and 11 is formed, and these passages 13 are sequentially connected by the through holes 12.

The mixing apparatus according to the present invention is constructed as described above, and a plurality of passage forming members 6 are superimposed inside the cylindrical body 2 so that the through holes 12 are alternately arranged on both sides with the same surface facing upward. The passage 13 is formed by fitting the opposing projections 10 and 11 of the passage forming member 6, and both ends of the cylindrical body 2 are sealed with the upper lid 3 and the lower lid 4 to assemble the mixing device.

In order to mix the liquids, a plurality of different liquids may be injected from the inlet 7 of the upper lid 3, and the liquids are mixed as shown in FIG.
As shown by arrows in FIG. 5, the gas flows sequentially through the through holes 12 and the passages 13 and flows out from the outlet 8 of the lower lid 4.

When a plurality of types of liquids flow through the passage 13, as shown by arrows in FIG. 2, they pass through portions having different cross-sectional areas, so that their flow speeds and pressures are changed. Mixing is surely performed by repeating the merging, and the mixing is performed many times by the large number of passages 13 and flows through the closed container body 1. Therefore, it is possible to create a complete mixed liquid without mixing air at all. it can.

In the mixing apparatus of the present invention, since the passage forming members 6 having the same structure are housed in the tubular main body 2 in an overlapping manner, they are sequentially inserted into the cylindrical body 2 with the same surface of the passage forming member 6 facing upward. Since it can be assembled with simple operations, there is no concern that the order of parts is incorrectly stacked, and disassembly, cleaning, and assembly can be easily performed, it is most suitable for food mixing.

In addition, in mixing food, non-rusting steel must be used as a constituent material of the mixing apparatus, and such a material is difficult to machine such as cutting.
When the projections 10 and 11 provided on the passage forming member 6 are configured to be arranged in a straight line, there is an advantage that processing is easy and cleaning can be easily performed.

[0020]

As described above, according to the present invention, plural kinds of liquids can be surely mixed, and a complete mixed liquid can be produced without mixing air at all. Further, since it is only necessary to sequentially stack the passage forming members having the same structure and store them in the tubular main body, disassembly, cleaning, and assembly can be easily performed.
Suitable for mixing food.
