Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mixer for swinging a mixing container.

[0002]

2. Description of the Related Art There are many types of mixers such as a container rotating type, a container fixed type, an air stirring type and a continuous type. There is also a mixer system using a high-speed rotating cutter, but compared to the container rotating type, other systems have many problems such as, for example, replacement of raw materials, a large amount of sample is required, some raw materials do not like metal contact . Most are too large to be used as test machines. Since the respective uses are different, the present invention is compared with a container rotating type for similar uses. V-type, double-cone type, rotary-oscillation type, etc. were used as conventional container rotary-type mixers. V-type, double-cone type, and rotary-oscillation type lift and lower the raw material by rotating the container. The raw material slides down in the container by its own weight, and is mixed by this flow.

[0003]

The above mechanism has the following problems.

[0004] In a rotary container mixer, rotation cannot be performed beyond the natural fall of the raw material. However, in the case of natural fall, those with a large specific gravity difference and raw materials with a large particle size difference are separated from each other,
High precision mixing and dispersion are not possible.

In the research stage, it is necessary to select various shapes and materials of the mixing container, and it is desired to use the storage container as the mixing container without refilling the raw material into the mixing container.

In addition, there are cases where it is desired to add a physical factor such as vacuum or heating. However, in a conventional rotary mixer, the degree of freedom of such attachment or change is very small mechanically.

There are cases where it is desired to measure a safety device against abnormal vibrations or the actual frequency.

There is also a mixing container in which the raw material adheres to the mixing container and tends to be unbalanced.

Therefore, an object of the present invention is to provide a mixer which solves the above problems.

[0010]

In order to achieve the above object, in the present mixer, a motor, a crank into which a spherical bearing is inserted, and a swing shaft in which a vertically arranged housing for a spherical bearing is assembled, A clamp is fixed to the upper end of the swing shaft, and a holder is assembled.

[0011] The rotation of the motor used in the present invention is transmitted to the crank, the spherical bearing is rotated, and the housing for the spherical bearing fixed to the rocking shaft is rotated, whereby the rocking shaft moves up and down and twists. The clamp fixed to the upper end and the holder assembled to the clamp,
This is to move the mixing container held by the holder up and down and torsion in two dimensions.

[0012] Regarding the sticky raw material, a gap having a movable space for the mixing container is held by a holder, and a directional frictional material such as a folded fold or the like is attached to the inner surface of the clamp. As a result, the mixing container that is violently moving up and down and twisting rotates in the gap, thereby preventing the wall of the mixing container from adhering.

Alternatively, it is possible to prevent the mixing container from rotating and prevent the mixing container from adhering to the wall surface of the mixing container by holding the mixing container with a gap so that the mixing container can move and holding a material having a different friction coefficient between the lid and the bottom of the clamp. it can.

Alternatively, the gap between the clamp and the mixing vessel can be moved, the inner surface of the clamp has a spherical shape, and the outer surface of the mixing vessel has a spherical shape.

As a means for rotating the mixing vessel, a method of rotating a clamp using a motor may be used.

In the case of raw materials having low adhesiveness, the mixing vessel may be surely grasped by the clamp and moved completely integrally with the clamp.

If the holder and the clamp are manufactured according to the capacity of the mixing vessel, it can be applied to a wide range. When large and small mixing containers are mixed, make a clamp to fit the large mixing container, and put the small mixing container in a capsule that can rotate the mixing container and hold it with a clamp or wrap it in styrofoam etc. and attach it You can also.

The clamp may be directly attached to the swing shaft, and the holder may be omitted.

Mixing in various atmospheres can be performed by attaching a vacuum or an environment-added component such as gas filling, heating, or cooling to the holder or the clamp.

By mixing glass beads, ceramic balls, stainless steel balls and the like with the raw materials, a ball mill having a very high crushing ability can be obtained.

According to the present invention, the container is shaken in a two-dimensional direction at a speed higher than the acceleration of gravity, whereby the raw material in the container and the raw material, and the raw material and the wall surface of the container are repeatedly violently collided. Container rotation type mixer is practical 20
0r. p. It is several times that of m or less. In particular, since the acceleration is the square of the velocity, the mixing and dispersing effects on the raw materials are increased by an order of magnitude, so that even raw materials having different specific gravities or high viscosity materials can be mixed and dispersed very quickly and with high precision. Become. In this way, what was impossible with the conventional container-rotating type mixer becomes possible, and extremely advantageous effects are obtained.

By rotating or rotating the container, even if the raw material adheres to the inner surface of the mixing container, the direction of the force acting on the raw material changes, and the raw material can be evenly dispersed while repeating adhesion and peeling.
