Problems solved by technology

[0012] However, in the mixer for high-viscosity fluid described in the above-mentioned patent document 1, the outer shape of the impeller is a hexagonal prism, and the outer wall of the impeller mainly collides with the agitated object to make the agitated object flow. Sometimes there is a problem of reaction force, and the problem of crushing the powder particles in the stirred material
[0013] In addition, although the material to be stirred flows out from the hole on the side, the volume inside the impeller is too large compared to the hole on the side, so the flow rate inside the impeller is low, and the retentate will adhere to and accumulate inside the impeller during long-term use, and the stirring ability will easily decrease.

no. 1 approach

[0077] First, the structure of the stirring rotating body 1 according to the first embodiment of the present invention will be described. figure 1 (a) is a top view of the rotating body 1 for stirring, figure 1 (b) is a front view of the rotating body 1 for stirring (the side view is the same). As shown in the accompanying drawings, the stirring rotating body 1 includes: a roughly hemispherical body 10, a plurality of suction ports 12 arranged on the surface of the body 10, and a plurality of discharge ports 14 arranged on the surface of the body 10, formed inside the body 10 A flow path 16 that connects the suction port 12 and the discharge port 14 .

[0078] In this example, the shape of the body 10 is substantially hemispherical, specifically, the bottom surface 10b of one side of the disk is formed into a spherical shape. At the center of the bottom surface 10a on the other side of the main body 10, a connecting portion 18 for connecting a drive shaft 20 of a driving dev...

no. 2 Embodiment approach

[0123] Next, the structure of the stirring rotating body 100 according to the second embodiment of the present invention will be described. Figure 12 (a) is a plan view of the rotating body 100 for stirring, Figure 12 (b) is a front view of the rotating body 100 for stirring (the side view is the same), Figure 12 (c) is a bottom view of the rotating body 100 for stirring. As shown in the accompanying drawings, the rotating body 100 for stirring includes: a cylindrical body 110; a plurality of suction ports 112 arranged on the surface of the body 110 (bottom surface 110b); a plurality of discharge ports 114 arranged on the surface of the body 110 (side surface 110c) ; Formed inside the main body 110 and connecting the flow path 116 of the suction port 112 and the discharge port 114 .

[0124]The main body 110 is formed in a 12-prism shape by providing 12 protrusions 110d on the outer peripheral surface (side surface 110c) of the cylinder (details will be described later). ...

no. 3 approach

[0200] Next, the structure of the stirring rotating body 300 according to the third embodiment of the present invention will be described. Figure 32 (a) is a plan view of the rotating body 300 for stirring, Figure 32 (b) is a front view of the rotating body 300 for stirring (the side view is the same), Figure 32 (c) is a bottom view of the rotating body 300 for stirring. Figure 33 It is a partial sectional view of the rotating body 300 for stirring. As shown in the figure, the rotating body 300 for stirring includes a hemispherical body 310; a plurality of suction ports 312 arranged on the surface of the body 310; a plurality of discharge ports 314 arranged on the surface of the body 310; Port 312 and flow path 316 of discharge port 314.

[0201] In this example, the body 310 is in the shape of a sphere divided into two. Therefore, the surface of the body 310 has a planar upper surface 310 a perpendicular to the central axis C of the body 310 , and a spherical inclined...

Abstract

The invention relates to a stirring rotating body and a stir device which are able to perform safe and efficient stirring irrespective of applications. A stirring rotating body (1) is provided with a body (10) which rotates about the rotation axis (C) thereof, suction openings (12) which are provided in the surface of the body (10), discharge openings (14) which are provided in the surface of the body (10), and flow paths (16) which connect the suction openings (12) and the discharge openings (14). The suction openings (12) are disposed at positions located closer to the rotation axis (C) than the discharge openings (14). The discharge openings (14) are disposed at positions located further toward the outside in the centrifugal direction from the rotation axis (C) than the suction openings (12).

Description

technical field [0001] The present invention relates to a stirring rotary body and a stirring device for stirring liquids and other various fluids for mixing, dispersing, and the like. Background technique [0002] Conventionally, when mixing two or more fluids or uniformly dispersing various powders added to the fluids, a stirrer that rotates an impeller in the fluid has been used. Usually, the impeller is provided with a propeller blade or a turbine blade, and the fluid is stirred by rotating the blade. [0003] The above-mentioned mixers are mostly fixedly installed in a water tank containing liquids. In addition, portable mixers are often used to perform on-site mixing before using, for example, paint. In this portable mixer, an impeller is generally arranged at the front end of the drive shaft of the hand drill type drive device. The user holds the driving device with both hands, inserts the impeller at the front end into the container containing the material to be st...
