Description

[Detailed description of the invention] This invention relates to a blade body mainly applied to a stirrer for mixing glaze.

Glaze, which is generally applied to the surface of unglazed ceramics to give it a gloss and to prevent liquid from seeping in, is made by injecting water into powders of feldspar, silica, limestone, lead oxide, borax, etc., and stirring the mixture as appropriate. made by mixing. Such a mixing operation is carried out by placing the above-mentioned powder and water in a synthetic resin container, and then inserting into the container a stirring blade attached to the tip of a rotating shaft driven by an electric drill.

However, the above-mentioned stirring blade has a propeller-like structure in which a plurality of metal blade pieces are attached radially to a base body that is attached to a rotating shaft. The blades being rotated at high speed hit the inner surface of the container and the container is damaged by the impact, causing the inconvenience that the glaze spills out. Therefore, great care must be taken when handling conventional stirrers, and the fear of damaging the container inevitably results in insufficient stirring near the inner surface of the container. Furthermore, when stirring the glaze near the liquid surface, there is a drawback that the glaze is scattered in all directions by the blades rotating at high speed.

This idea was developed in view of the above-mentioned drawbacks of the conventional technology, and has a structure in which the blade body provided with suction grooves and the disk portion provided with discharge holes are integrally formed into a covered cylindrical shape with a truncated conical outer shape. Accordingly, it is an object of the present invention to provide a stirring blade body that eliminates all of the conventional drawbacks.

Hereinafter, preferred embodiments of this invention will be described in detail based on the drawings.

In the figure, reference numeral 1 denotes a disc part, in which three circular discharge holes 2 are bored on the same circumference, and a nut 5 is attached to the tip of a rotating shaft 4 whose center part is attached to an electric drill 3.
It is fixed by. Reference numeral 6 denotes a blade body, which is a cylindrical body with a truncated conical outer shape, and its small diameter opening is connected to the periphery of the disk portion 1, and the entire body is integrally molded from synthetic resin into a closed cylindrical shape. .
This blade body 6 has suction grooves 7 formed at three locations and is divided into three arc-shaped blade pieces 8. As shown in FIG. The other cut surface 7b is formed approximately in the tangential direction of the inner circumferential surface of the blade body 6.

The example blade body having the above structure is rotated by the drive of the electric drill 3 and immersed in the glaze B of the synthetic resin container A as shown in FIG.
Glaze B is stirred by three blade pieces 8 rotating at high speed. In such a case, the blade body is rotated in the direction of the arrow in FIG.
It is discharged from. At this time, due to the fact that the directions of the opposing facets 7a and 7b of the suction groove 7 are different, and because one facet 7a is connected to the discharge hole 2 in the tangential direction thereof, the blade body 6 is The glaze B that has entered is sufficiently stirred without being discharged as it is from the discharge hole 2. In addition, since the mixture is flowed through the path as described above, it is particularly effective in mixing sticky substances such as glazes, which are made up of multiple types of powders.

Since the outer shape is cylindrical, even if it comes into contact with the inner surface of container A during high-speed rotation,
Coupled with the fact that the material is synthetic resin, the impact is not very large and the container A will not be damaged or damaged. Therefore, the vicinity of the inner peripheral surface of the container A can also be sufficiently stirred. Furthermore, when mixing the liquid level part of glaze B, since the outer surface is cylindrical with a downwardly widening shape, even if the blade body is moved up and down at the liquid level part, the glaze B will not be able to resist the action of centrifugal force due to rotation. It runs down the outer surface of piece 8 and does not scatter.

Incidentally, it is sufficient to prepare several types of inclination angle of the blade body 6, diameter of the discharge hole 2, etc. according to the degree of viscosity of the mixture, and to select and replace the rotary shaft 4 as appropriate.

As mentioned above, according to the stirring impeller body of this invention, the disc portion with the discharge holes and the cylindrical impeller body having a truncated conical outer shape are integrally formed into a closed cylinder shape, and the impeller Since the barrel is divided by multiple suction grooves, even if it comes into contact with the inner surface of the container for mixing at high speed, it will not be damaged, and the parts near the inner surface of the container will be sufficiently covered. Furthermore, since it has a cylindrical shape, it is possible to mix the upper surface of the mixture without scattering it. Moreover, since the mixture is fluidized and stirred by entering it through the suction groove into the blade body and discharging it from the discharge hole, it can be applied to a stirrer for viscous mixtures, such as glazes, and has extremely significant practical effects. It is something that can be done. Moreover, unlike conventional propellers, the outer shape is a cylinder with a lid, so unlike conventional propellers, the material is not limited to metal, and can be made of synthetic resin with sufficient strength and cost. It has the great advantage of being able to reduce the size of plastics and utilize the features of synthetic resins.
