Abstract

PURPOSE:To defoam and mix uniformly powder and liquid carrying different specific gravity values by actuating simultaneously a process of stirring with a resting paddle inserted in, a process of reducing pressure and removing air, and a process of effecting vibration in a rotating container. CONSTITUTION:A container 17 is set on a hoop 12, a material 20 being put into the container 17, and a paddle 19 is set on. By rotating the hoop 12, the container 17 rotates with a paddle 19 resting still, and a material 20 is stirred and mixed. At that time, a vibrator switch 22 is turned on to actuate a vibrator 2 mainly upward and downward to apply a high-speed micro-vibration to the material 20. The material 20, therefore, moves by the particle level to crush, disperse and transfer agglomerates. Thus, the material 20 is mixed with a high average by a macrostirring with the paddle 19 and a micro-stirring with the high-speed micro-vibration. At the same time, because of said movement by the particle level, kinetic pressure is given to the adhering foams under a reduced pressure and rupture the same to defoam the material 20 in a short period of time.

Description

Detailed Description of the Invention: & Detailed Description of the Invention Field of Industrial Application This invention relates to a method and an apparatus for mixing and defoaming substances or powders and liquids having different specific gravities in a diotherm or the like.

Conventional technologyIn the past, substances with different specific gravity values, such as guiotansi,
Alternatively, mixing and defoaming of powder and liquid used a stirring action in which the paddle rotates fully in a vacuum container.0 Problems that the invention aims to solveHowever, it is difficult to simply stir materials with different specific gravity values. It is difficult to mix evenly, and when mixing the above-mentioned substances and powders with liquids, air bubbles are difficult to remove, and defoaming takes a long time.

Method and Means for Solving the Problems The present invention applies high-speed vibration to a reduced pressure container equipped with a stirring device, vibrates the contained substance at a particle level, and diffuses and moves the substance. It separates air bubbles that adhere to substances, and performs average mixing and defoaming in a short period of time.

EXAMPLE Hereinafter, an example of the implementation of the method and apparatus of the present invention will be explained with reference to the drawings. Reference numeral 1 denotes an upper base, 2... vibrators, which are supported on the lower surface of the four corners of the upper base l, as shown in FIG. It is controlled by an air control device 3 as shown and connected to an external air tank, and vibrates when supplied with air.

4 is a lower base, and there are mounting bosses 5 at four locations on the upper surface of the lower base.

On the inner diameter of the mounting boss 5... is a shaft sliding bearing metal 8...
・ are installed respectively. In addition, a through hole (not shown) is opened in the lower base 4 and communicates with the mounting boss 5.
The lower end of each support shaft 6 is loosely fitted.

A motor 9 is installed under the lower base 4, and its rotation is transmitted by a belt 11 to a speed reducer 10 supported on the central lower surface of the upper base 1. transmitting the requiredly decelerated rotation to the hoop ν mounted on the upper surface of the central portion of the upper base 1;
Rotate this.

An annular backing 13 for a tank is installed on the upper surface of the upper base 1 outside the hoop 4, and a top tm bright acrylic plate 14 is installed.
The tank 15, which is closed at the bottom and open at the lower end, is covered with the backing 13K, and when the vacuum pump switch 23 is turned on, the air inside the tank is sucked through the vacuum suction nozzle 16 protruding from the upper surface of the upper base 1, and the inside is drained. It is provided to reduce the pressure as required.

A container 17 containing 20 materials is fixed to the container 2, and a paddle 19 is inserted into the container 17, which is attached to a support rod 18 that stands up from the top of the upper base and is stationary. It looks like this.

Operation Next, the operation of the method and apparatus of the present invention will be explained.The container 17 is set in the container 7-12. powder and solvent liquid,
That is, 20 materials are put into the container 17. capacity 517K
Ha, set the required amount of $19. motor switch 2
When the motor 9 is inserted, the motor 9 rotates, and the rotation is reduced by the reducer lO, and the hoop 12 rotates at, for example, 45 PPM.The container 17 rotates relative to the paddle 19, which is stationary.
Stir and mix 2 o of the ingredients inside. vibrator at the same time
When the switch A high-speed micro-vibration is applied to the material I inside.

The trowel material m moves at the particle level, and there is no sound of collision with each other, and the agglomerates are broken up and moved by diffusion. In this way, the materials 20 are mixed both macroscopically by the stirring action of the paddle 19 and microscopically by the high-speed microvibration to a high average ratio. At the same time, as mentioned above, motion is applied at the particle level, giving kinetic pressure to the air bubbles that adhere between them, and since it is also under reduced pressure, the air bubbles burst, allowing air to be removed from every corner of the material field in a short period of time. can. Here, turn off the vibrator switch 22, stop the operation of vibrator 2...
Further, the motor switch 21 is turned off to stop the rotation of the container 17. Then, turn off the vacuum pump switch 23t to stop depressurization, return the inside of the vacuum tank 15 to normal pressure, and
5. Remove the metal and remove the inner hoop container 17 to complete the addition of materials, mixing, and defoaming. Since it provides stirring and vibration at the same time, it is possible to mix substances with different specific gravity values, such as powder and liquid, at a high average rate and achieve almost complete defoaming in an extremely short time. It can be done.
