Description

Detailed Description of the Invention

[0001]

The present invention relates to medical products, food products, chemical products,
The present invention relates to a stirring blade suitable for mixing and stirring or kneading powder and liquid used for building materials and the like.

[0002]

2. Description of the Related Art As a conventional mixing and stirring blade for mixing and kneading powder and liquid, as shown in FIG. 5, blades c and c each made of a flat plate are provided at a lower end portion and an intermediate portion of a rotary shaft a, and a boss portion b. b
Is known to be fixed to the rotating shaft a.

[0003]

When the powder and the liquid are stirred or kneaded by the stirring blade composed of the two-stage blades as described above, a part of the powder supplied from the upper part of the container is the upper blade. There is a problem that the powder adheres to or adheres to the boss portion of the product and hinders the subsequent supply of powder or liquid, and that it becomes difficult to remove the powder adhered to the boss portion after completion of the stirring or kneading operation. It was

SUMMARY OF THE INVENTION It is an object of the present invention to solve these problems and to provide a stirring blade composed of a multi-stage blade in which there is no fear of powder sticking to the boss portion.

[0005]

In order to achieve the above object, the present invention has a first stirring blade projecting laterally at the lower end of a rotary shaft and a vertical portion at the tip of the first stirring blade. A vertical stirring blade is provided upright, and a second stirring blade is projected inwardly toward the rotary shaft at the upper end of the vertical stirring blade.

[0006]

In the stirring blade according to claim 1, since the second stirring blade is installed at the upper end of the vertical stirring blade which is erected at the tip of the first stirring blade, the second stirring blade has the rotating shaft. Since there is no boss portion between and, there is no concern that powder or the like will stick to the boss portion.

In the agitating blade of claim 2, since the vertical agitating blade is formed in the shape of a curved strip, the object to be agitated becomes an ascending flow in the peripheral portion of the container and a descending flow in the central portion. As a result, a vertical circulation flow that spreads throughout the container is formed, and efficient stirring can be performed.

In the stirring blade of the third aspect, since each blade of the first stirring blade and the second stirring blade is an inclined belt-like member and has an opening, the kneading effect on the object to be stirred is high.

In the stirring blade according to the fourth aspect, since the auxiliary blade having the opening in the band plate is arranged between the first stirring blades,
It has a simple structure and sufficient performance as a stirring blade.

In the stirring blade according to claim 5, the first stirring blade has a substantially equal distance from the bottom surface of the container at any position in the longitudinal direction, so that the bottom surface has an arc surface or the container. Even when the corners of the bottom face are round, there is no interference with the blades, and liquids and the like near the bottom face are reliably stirred and kneaded.

In the stirring blade according to claim 6, since the second stirring blade and the third stirring blade are provided at the upper end portion and the intermediate portion of the vertical stirring blade that is erected at the tip portion of the first stirring blade, respectively It can be adapted to the needs of stirring and kneading in containers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 indicates a stirring blade main body, 2 indicates its rotation axis,
A first stirring blade 1b consisting of two strip-shaped plates is radially provided on the rotary shaft 2 via a boss 1a so as to have a predetermined inclination angle, and the tip end of the first stirring blade 1b is further provided. The vertical stirring blade 1c of the curved strip plate is erected at a predetermined inclination angle,
One side end of each vertical stirring blade 1c is arranged so as to be close to the inner peripheral surface of the container 3, and is formed to have a spiral shape.

A second stirring blade 1d is provided at the upper end of the vertical stirring blade 1c so as to project inward toward the axis of the rotary shaft 2, and the middle of the two first stirring blades 1b. Auxiliary wings 1e made of a strip plate are radially provided at the position from the boss 1a with a predetermined inclination angle.

The first stirring blade 1b and the second stirring blade 1d
The auxiliary blade 1e is provided with a square opening 1f.

Next, the operation of the first embodiment of the present invention will be described.

The rotary shaft 2 is rotatably supported above and is driven by a motor (not shown) to rotate together with the stirring blade main body 1 in the direction of arrow A. The powder and liquid supplied into the container 3 are stirred and kneaded by the first stirring blade 1b and the auxiliary blade 1e, and the vertical stirring blade 1c is inclined and curved.
The kneaded material of the powder and the liquid in the peripheral portion of the container 3 moves upward in the container 3.

The second provided at the tip of the vertical stirring blade 1c
The stirring blade 1d has an effect of further kneading the rising kneaded material of the powder and the liquid and sufficiently stirring and kneading even when the amount of the kneaded material in the container 3 is large.

Further, the first stirring blade 1b and the second stirring blade 1
The d and the opening 1f of the auxiliary blade 1e act to enhance the kneading effect on the material to be kneaded.

The rotary shaft 2 may be rotated in the opposite direction of the arrow A, if necessary.

A second embodiment of the present invention is shown in FIG.

In the present embodiment, the stirring blade main body 1 has a third stirring blade 1g, in addition to the first stirring blade 1b, which is protruded toward the rotary shaft 2 from an intermediate portion of a vertical stirring blade 1c formed long. Since the second stirring blade 1d is projected from the tip portion of the vertical stirring blade toward the rotary shaft 2, the amount of the agitated / kneaded material in the container 3 is large and the upper part of the container 3 is filled. Even in this case, the ability to perform stirring and kneading is highly effective.

In the above embodiment, the first stirring blade 1
Although b, the vertical stirring blade 1c, the second stirring blade 1d, etc. are all plate-shaped blades, they may be twisted blade shapes to reduce the stirring resistance.

Further, the number of various blades may be increased or decreased as necessary.

[0025]

As described above, according to the present invention, in the stirring blade composed of multi-stage blades, since the upper blade has no mounting boss, the powder is mixed in the upper boss portion even when the powder and the liquid are stirred and kneaded. It has the effect that efficient stirring and kneading can be performed without worrying about the body sticking.
