Description

[0001]
[Industrial application fields]
The present invention relates to a stirring blade suitable for mixing and kneading powder and liquid used for medical products, foods, chemicals, building materials and the like.
[0002]
[Prior art]
As a conventional stirring blade for mixing and mixing powder and liquid, as shown in FIG. 4, blade bodies c and c each having a flat plate at the lower end portion and the middle portion of the rotating shaft a are respectively connected to the rotating shaft at the boss portions b and b. It is known that it is fixed to a.
[0003]
[Problems to be solved by the invention]
When the powder and liquid are agitated or kneaded with the stirring blade composed of the two-stage blade as described above, a part of the powder supplied from the upper part of the container adheres to or adheres to the boss of the upper blade. In addition to hindering the supply of the subsequent powder and liquid, there are problems such as difficulty in removing the powder fixed to the boss after the stirring or kneading operation.
[0004]
An object of the present invention is to solve these problems and to provide a stirring blade composed of a plurality of blades without worrying that powder adheres to the boss portion.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has a first stirring blade projecting laterally at the lower end portion of the rotating shaft, and a vertical stirring blade standing at the tip of the first stirring blade, A second agitating blade is projected inwardly toward the rotating shaft at the upper end of the saddle-shaped stirring blade, and the saddle-shaped stirring blade is formed of a belt-like plate bent in a curved shape. .
[0006]
[Action]
The stirring blade according to claim 1, wherein the second stirring blade is installed at the upper end of the vertical stirring blade standing at the tip of the first stirring blade, so that the second stirring blade is located between the rotary shaft and the second stirring blade. There is no boss portion, so there is no concern that powder or the like sticks to the boss portion. In addition, since the saddle-shaped stirring blade is formed in a curved belt-like body, the object to be stirred becomes an upward flow in the peripheral portion of the container and a downward flow in the central portion and reaches the entire inside of the container. A circulating flow is formed and stirring can be performed efficiently.
[0007]
In the stirring blade according to claim 2, since each blade of the first stirring blade and the second stirring blade is an inclined band-like body and has an opening, the kneading effect on the object to be stirred is high.
[0008]
According to the third aspect of the present invention, since the auxiliary blade having an opening with a belt-like plate is disposed between the first stirring blades, it has sufficient performance as a stirring blade with a simple configuration.
[0009]
5. The stirring blade according to claim 4, wherein the first stirring blade has a substantially equal distance from the bottom surface of the container at any position in the longitudinal direction thereof, so that the bottom surface has an arc surface or the bottom surface angle of the container. Even when the part is round, there is no interference with the blade, and the liquid in the vicinity of the bottom face is reliably stirred and kneaded.
[0010]
6. The stirring blade according to claim 5, wherein the first stirring blade is provided with the second stirring blade and the third stirring blade at the upper end portion and the middle portion of the vertical stirring blade standing at the tip portion, respectively, so that stirring in a vertically long container is performed.・ Can be adapted to kneading needs.
[0011]
【Example】
A first embodiment of the present invention will be described with reference to FIGS.
[0012]
Reference numeral 1 denotes a stirring blade body, 2 denotes a rotation shaft thereof, and a first stirring blade 1b composed of two strip-shaped plates is radially projected from the rotation shaft 2 through a boss 1a with a predetermined inclination angle. In addition, a curved strip-shaped plate-shaped stirring blade 1c is erected at a tip end portion of the first stirring blade 1b with a predetermined inclination angle. It arrange | positions so that it may adjoin to an internal peripheral surface, and it is formed so that a spiral shape may be exhibited.
[0013]
A second stirring blade 1d is provided at the upper end of the bowl-shaped stirring blade 1c so as to project inward toward the axis of the rotary shaft 2, and a belt-like shape is provided at an intermediate position between the two first stirring blades 1b. The auxiliary wings 1e made of a plate project radially from the boss 1a with a predetermined inclination angle.
[0014]
The first stirring blade 1b, the second stirring blade 1d, and the auxiliary blade 1e are provided with square openings 1f.
[0015]
Next, the operation of the first embodiment of the present invention will be described.
[0016]
The rotating shaft 2 is supported on the upper side, is driven by a motor (not shown), and rotates together with the stirring blade 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 bowl-shaped stirring blade 1c is inclined and curved. The kneaded product of the powder and liquid moves up in the container 3.
[0017]
The second stirring blade 1d provided at the tip of the bowl-shaped stirring blade 1c further kneads the rising powder and liquid kneaded material, and is sufficient even when the amount of the kneaded material in the container 3 is large. Has the effect of stirring and kneading.
[0018]
The openings 1f of the first stirring blade 1b, the second stirring blade 1d, and the auxiliary blade 1e serve to enhance the kneading effect on the material to be kneaded.
[0019]
In addition, you may rotate the said rotating shaft 2 in the direction opposite to said A arrow as needed.
[0020]
A second embodiment of the present invention is shown in FIG.
[0021]
In this embodiment, the agitating blade body 1 is protruded from the intermediate portion of a bowl-shaped stirring blade 1c formed with a long third stirring blade 1g in addition to the first stirring blade 1b toward the rotary shaft 2, and the bowl-shaped stirring blade 1g. Since the second stirring blade 1d protrudes from the tip of the blade toward the rotary shaft 2, stirring is performed even when the amount of the stirring / kneaded material in the container 3 is large and fills up to the top of the container 3. And the ability to knead is highly effective.
[0022]
In the above embodiment, the first stirring blade 1b, the saddle-shaped stirring blade 1c, the second stirring blade 1d, etc. are all plate-shaped blades, but they may be twisted to reduce stirring resistance. Good.
[0023]
Further, the number of various wings may be increased or decreased as necessary.
[0024]
【The invention's effect】
As described above, according to the present invention, in the stirring blade composed of multistage blades, the upper blade has no mounting boss, and therefore, the powder may adhere to the upper boss portion even when the powder and liquid are stirred and kneaded. And there is an effect that stirring and kneading can be performed efficiently.
