Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a multi-liquid mixing and discharging device.

Summary of the invention The present invention is a mixing and stirring shaft that is removably inserted into the mixing and stirring chamber of the mixing container and receives the liquid to be mixed injected from a plurality of injection ports communicating with one side of the mixing and stirring chamber located in the mixing container. In a multi-liquid mixing and discharging device that mixes and stirs with a mixing and stirring blade and discharges from a discharge port communicating with the other side of the mixing and stirring chamber, the mixing container includes an inner container forming a mixing and stirring chamber, and this inner container. By comprising an outer container that is detachably stored, cleaning work is simplified and work efficiency and safety are improved.

Conventional technology and its problems Conventionally, as a multiple liquid mixing and discharging device, for example,
As shown in FIGS. 2 to 5, the mixing container 1
and a mixing and stirring shaft 10 that is removably inserted into the mixing container 1.

That is, the mixing container 1 has a mixing and stirring chamber 2 in its center, and one end of the mixing and stirring chamber 2 has an opening 3 into which a mixing and stirring shaft 10, which will be described later, can be inserted.
In the vicinity of this opening 3, two injection ports 4 and 5 communicating with the mixing and stirring chamber 2 are provided. At the other end of the mixing and stirring chamber 2, there is a discharge port 6 for discharging the mixed and stirred liquid to be mixed.
is provided. In addition, 7 is a fixing flange part,
Reference numerals 8 and 9 are connection devices for a pipe (not shown) for injecting a liquid to be mixed.

The mixing and stirring shaft 10 has a large number of star-shaped mixing and stirring blades 11 arranged side by side at equal intervals on approximately half of one side thereof, and when inserted into the mixing and stirring chamber 2 of the mixing container 1, the mixing and stirring The tips of the blades 11 are adapted to come into sliding contact with the inner wall surface of the mixing and stirring chamber 2.

However, in the conventional method, the liquid to be mixed is
For example, in the case of adhesive, it is possible to clean the mixture by injecting a solvent into the mixing and stirring chamber 2 after the work is completed, or by disassembling the mixing container 1 and mixing shaft 10 and washing them with a solvent. The adhesive adhered to and hardened on the inner wall surface of the stirring chamber 2 and the surface of the mixing stirring blade 11 could not be completely removed.

In particular, if the liquid to be mixed is highly toxic, there is a problem in that the liquid to be mixed will adhere to hands and the like when the mixing container 1 and the like are disassembled and cleaned, which is unfavorable in terms of safety and hygiene.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention consists of a mixing container consisting of an inner container that forms a mixing and stirring chamber, and an outer container that removably houses the inner container. be.

Operation and Effect Therefore, according to the present invention, since the inner container and the mixing agitation shaft that constitute the mixing container can be removed from the multi-liquid mixing and discharging device, the old inner container and mixing agitation shaft can be removed after the work is completed. If you replace it with a new one, you can omit the cleaning work. For this reason, work efficiency is improved, and harmful mixed liquids are prevented from adhering to hands, etc., which is advantageous in terms of safety and health.

Embodiment An embodiment of the present invention will be described below with reference to FIG.

The multiple liquid mixing and discharging device 20 according to this embodiment is as follows:
It is composed of a mixing container 21 consisting of an inner container 22 and an outer container 23, and a mixing and stirring shaft 30.

That is, the inner container 22 is a resin molded product equipped with a mixing and stirring chamber 24 that can accommodate the mixing and stirring blades 31 of the mixing and stirring shaft 30, and the mixing and stirring shaft 30 is mounted on one side of the inner container 22.
It has an opening 25 for inserting the liquid, and a discharge port 26 for discharging the mixed and agitated liquid on the other side. Note that the opening 25 can communicate with injection ports 36 and 37 arranged inside the mounting base 35.

The outer container 23 has a substantially cylindrical shape into which the inner container 22 can be inserted detachably, and can be fixed to the receiving part 39 of the mounting base 35 with a ring-shaped fastener 38 via a flange part 26 provided at the outer peripheral end. It's getting old. Note that 27 and 28 are sealing materials.

The mixing stirring shaft 30 is a resin molded product, and has a large number of mixing stirring blades 31 arranged side by side at equal intervals on approximately half of one side, and the remaining shaft portion 3 on approximately half of the one side.
2 is removably inserted into the aforementioned mounting base 35 and is rotatable. The tip end of the mixing and stirring blade 31 is shaped to be able to come into sliding contact with the inner wall surface of the mixing and stirring chamber 24 when inserted into the mixing and stirring chamber 24 .

To assemble the multiple liquid mixing and discharging device 20 according to this embodiment, the mixing and stirring shaft 30 is attached to the mounting base 35.
A mixing stirring blade 31 that rotatably inserts and protrudes from the mixing stirring blade 31
The inner container 22 and the outer container 23 are fitted one after another, and the ring-shaped stopper 38 inserted into the outer container 23 is screwed into the receiving part 39 of the mounting base 35.
3 to the receiving portion 39 of the mounting base 35 to complete the assembly.

Therefore, when the mixing and stirring shaft 30 is rotated and the liquid to be mixed is injected into the mixing and stirring chamber 24 from the injection ports 36 and 37, the injected liquid to be mixed is mixed by the mixing and stirring blade 31 of the mixing and stirring shaft 30. After being stirred, it is sequentially discharged from the discharge port 26.

After the work is completed, the multiple liquid mixing and discharging device 20 may be disassembled by performing the reverse assembly work described above, the inner container 22 and the mixing and stirring shaft 30 may be replaced with new ones, and then assembled in the same manner as described above. It goes without saying that the disassembled inner container 22 and the like may be washed and reused as appropriate.

In this embodiment, the inner container 22, the mixing stirring shaft 30
is made of resin molded product, so it is inexpensive and
It has the advantage of being easy to manufacture.

Note that the shape of the mixing and stirring blade 31 is not limited to the above-mentioned shape, and may be appropriately selected as necessary.

Moreover, it goes without saying that two or more liquids may be mixed.
