Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixing device, and more particularly, to a mixing device for mixing objects to be mixed, which are a combination of different types of powder or liquid, in a mixing tank.

Generally, this type of mixing device has an outlet at the bottom of the mixing tank, a lid that can be opened and closed freely, and the materials to be mixed are directly charged into the mixing tank and stirred by a blade. After mixing by vibrating the mixing tank, the lid is opened and the mixture is taken out from the outlet.

As the substances to be mixed are mixed directly in the mixing tank, even after the operation is finished and the mixture is taken out, it is inevitable that some amount will remain attached to the inner wall of the mixing tank. Therefore, when mixing different types of substances to be mixed, there is a problem in that it is necessary to clean the inner wall of the mixing tank by removing the deposits each time.

Therefore, the present invention was devised to solve the above problems, and the purpose is to remove the substances from the mixing tank after mixing the substances, regardless of the type of substances to be mixed.
The entire amount can be taken out smoothly without any adhesion to the inner wall of the mixing tank, and the removal can be done quickly and easily. The object of the present invention is to provide a mixing device that does not require cleaning work of the inner wall.

That is, the present invention includes a film-like container having a volume approximately equal to the volume of the mixing tank inside the mixing tank, and a mounting means for tightly fitting the container into the mixing tank. This is a characteristic feature.

In the drawings, reference numeral 1 denotes a mixing tank in which materials to be mixed are mixed inside, a blade body 2 for stirring the materials to be mixed is rotatably installed inside, and the lower part of the mixing tank 1 is moved through a vibration device 3. It is attached to the stand 4. The vibration device 3 has a vertical shaft 5 on a pedestal 4, and an eccentric shaft 6 relative to the bottom wall of the mixing tank 1 and the vertical shaft 5,
These two shafts 5 and 6 are connected by cranks 7 and 7, and the vertical shaft 5 is connected to a motor 10 that is driven during mixing operation via a transmission 9 with a belt 8. is made to rotate in the lateral direction.

Therefore, in the mixing apparatus configured as described above, the present invention provides the mixing tank 1 with an air chamber 11 that opens into the mixing tank 1, and
The air chamber 11 is communicated with a compressor 12, and a means for mounting a film-shaped container 13 (to be described later) is provided. A container 13 is placed inside, and the container 1 is
3 in close contact with the inside of the mixing tank 1.

That is, in the case shown in FIG. 1, a large number of small holes 14 are provided on the entire surface of the mixing tank 1, and the outer shape of the air chamber 11 is formed to be larger than the outer shape of the mixing tank 1. , the mixing tank 1 is charged into the air chamber 11, and the mixing tank 1 is inserted into the air chamber 11.
The chamber 1 is supported via the spacer 15...
1 is communicated with the inside of the mixing tank 1 through small holes 14... A mounting body (none of which is shown) for a bomb and a rocker of the vibration device 3 is provided at the bottom of the chamber 11 to vibrate the mixing tank 1.

An air pipe 16 is connected to the air chamber 11, and the air pipe 16 is provided with branch pipes 17 and 18 that communicate with the suction side and the discharge side of the compressor 12, and the branch pipe 17 is opened during mixing operation. Valve 1 that closes when the container 13 is taken out
9, and small holes 14 on the entire inner surface of the mixing tank 1 during mixing operation.
A vacuum tank 20 having a capacity capable of suctioning the container 13 and holding it closely together without movement is interposed in series with the branch pipe 18, which is closed during mixing operation and when the container 13 is taken out. When the container 13 is taken out, the container 13 is opened through the small hole 14 .
A pressure tank 22 having a capacity that can release the pressure tank 22 from the inner surface of the mixing tank 1 is inserted in series.
Further, the compressor 12 used has a capacity corresponding to the respective capacities of the vacuum tank 20 and the pressure tank 22.

The film-like container 13 is formed by processing synthetic resin such as polyethylene by vacuum molding, injection molding, blow molding, etc., or by using an airtight material such as paper or metal material.
Attach the take-out handle 23 to the upper part of the outer surface as shown in the figure, and install the air chamber 1 from the upper part of the mixing tank 1.
A support piece 24 that is applied to the outer surface of the air chamber 11 is attached to the outer surface of the air chamber 11 during operation, and the support piece 24 that is applied to the outer surface of the air chamber 11 is held by a band 25 that has a rubber inner surface during operation. The air chamber 11 is also designed to support the air chamber 11 so that it does not move. Further, instead of the handle 23, a handle hole 26 may be provided in the upper part of the container 13 as shown in FIG. 3, and the area around the hole 26 may be reinforced with a reinforcing piece 27.

In the above configuration, during the mixing operation, the film container 13 is inserted into the mixing tank 1, the compressor 12 is operated, the valve 19 is opened, and the valve 21 is closed. By doing so, the pressure inside the air chamber 11 is reduced, and each small hole 1
4..., the film-like container 13 is attracted to the inner wall of the mixing tank 1, and is tightly supported on the entire surface of the inner wall.

In this state, the object to be mixed is charged into the container 13, and the blade body 2 and the vibrating device 3 are operated. Even in this operating state, the container 13 has no suction from each of the small holes 14... Due to this action, the container 13 does not move along the inner surface of the mixing tank 1 or become deformed by separating from the inner surface, and can maintain a state in which it is firmly attached to the inner surface of the mixing tank 1. Therefore, the container 13
The objects to be mixed can be reliably mixed within the chamber.

After the mixing operation is completed, the valve 19 is closed,
By opening the valve 21, the high pressure air in the pressure tank 22 acts on the container 13 through the air chamber 11, the small holes 14, . . . , and the container 13 is completely released from the inner surface of the mixing tank 1. Therefore, the container 13 can be taken out from the mixing tank 1 without any trouble by grasping and lifting the upper part, and the entire amount of mixed materials can be easily taken out from the container 13. Since no substances to be mixed adhere to the inner surface of the mixing tank 1, there is no need to clean the inner surface of the mixing tank 1 even when mixing different types of substances to be mixed.

In the above explanation, the blade body 2 and the vibrating device 3 are used to mix the substances to be mixed in the mixing tank 1, but the present invention can also be applied to a case where only one of the two is used. , the vibration device 3 can be applied to devices other than those shown in FIG. When the blade body 2 is used, it is preferable to form the center of the bottom surface of the mixing tank 1 into a substantially conical shape as shown by the dotted line in Figure 1. In this case, the container 1
The center part of the bottom surface of No. 3 is also of the same shape as shown in FIG.

Moreover, the container 13 is not provided with the support piece 24 as shown in FIG.
The upper end of the mixing tank 1 may be extended upward from the upper end of the mixing tank 1, and may be attached to the lower surface of the drive motor of the blade body 2 so as to be narrowed around the drive shaft, so that it has both a lid function and a handle function.

Further, the vacuum tank 20 and the pressure tank 22 may not be particularly provided.

As described above, in the present invention, a film-like container with a volume almost equal to the volume of the mixing tank is installed inside the mixing tank, and a mounting means is provided in the mixing tank to bring the container into close contact with the mixing tank. Therefore, after mixing the materials to be mixed, the materials to be mixed can be removed from the mixing tank with the very simple task of removing the film container from the mixing tank and removing the mixed materials from the container. The removal work can be quickly completed regardless of the amount of materials to be mixed. Moreover, even if you remove the materials, the materials to be mixed will not adhere to the inner surface of the mixing tank, so if you want to mix different materials, you can simply prepare a new film-like container and keep the inside of the mixing tank. There is no need to clean the surface at all, and the entire process is extremely simple.
