Description

[Detailed Description of the Invention] The present invention relates to a stirrer for stirring viscous liquids, particularly liquid materials such as paint, mortar, resin concrete I., and stucco.

Traditionally, propeller-type stirring blades or cutter-type stirring blades with edges on the top and bottom surfaces have been used as the blades of the stirrer for stirring the above-mentioned liquid materials, and when in use, a rotary shaft motor attached to these blades is used to generate high-speed rotation. The blades were inserted into a container containing liquid, and the agitator was turned down to stir the liquid.

Therefore, as the blade receives a large resistance from the liquid, it requires a lot of force to hold it in place, and it also requires a lot of force to immerse the blade in the liquid or to remove it from the liquid, which requires a lot of effort. It required

In addition, conventional stirrers only use the impact force of blades rotating on a horizontal plane to stir the liquid, so when the viscosity of the liquid material is high, the drive source requires a large output, and it is difficult to keep it in a fixed position. As long as the container is held, the liquid materials are only partially mixed, and it takes a very long time to stir and knead the entire liquid in the container.

Further, propeller-type stirring blades cause convection currents throughout the liquid due to their rotation, which increases the temperature of the liquid due to friction between molecules of the liquid, making them unsuitable for stirring thermosetting resin materials.

This project consists of a rectangular frame that has a horizontal part on the lower edge of -L and a vertical part on the outer edge that connects the upper and lower edges, and a rotating shaft that supports this. A portion of the liquid is confined within a three-dimensional contour formed between the hollow parts of the frame by tilting the frame in different directions at a certain angle and rotating the frame in a plane that includes the axis of the rotation axis. At the same time, external liquid is received or discharged within the contour along the sloped surface of the frame, and the viscosity of the liquid is actively used to effectively stir the liquid through interference and friction between the liquid inside and outside the contour. It is characterized by the fact that it performs the following.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figure 1A shows the agitator of the present invention.

That is, the stirrer M includes a rotating shaft 1 and a plurality of rectangular frames 2, 2, which serve as stirring blades supported by the rotating shaft 1.
Each frame body 2 is attached radially in three to five positions along the axis of the rotation axis 1 at a position on the same circumference and at an angle perpendicular or close to perpendicular to the axis of rotation axis 1. The relative position is set such that the hollow portion 2A of the rotary shaft 1 is located on a plane containing the axis of the rotating shaft 1 or at an angle with this plane.

The frame body 2 consists of horizontal parts 2B, 2C at the lower edge and a vertical part 2D at the outer edge thereof, with the upper and lower horizontal parts 2B.

The base of 2C is attached to the circumferential surface of the rotating shaft 1.

The horizontal portions 2B, 2C1 and vertical portions 2D of the frame 2 are tilted in different directions with respect to the rotation direction, and in the case of the embodiment, the horizontal portion 2B at the upper edge is rotated as indicated by the arrow in The horizontal part 2 of the lower edge is tilted at a certain angle along the direction.
An example is shown in which C is tilted downward, and the vertical portion 2D is further tilted in the diameter reduction direction along the rotation direction.

That is, as the frame body 2 rotates, liquid is received in the hollow part from either the horizontal part or the vertical part, and is discharged from the other part.

The frame body 2 may be made by bending a strip of steel plate or the like and fixing both ends of the bent steel plate to the circumferential edge of the rotating shaft 1 by direct welding or the like, or as shown in FIG. ，
Attach it to the outer surface of the cylindrical body 4 attached in step 3.

Further, the horizontal portions 2B, 2C and the vertical portion 2D of each frame 2 are provided with edges at their front edges in the direction of rotation, if necessary.

When using the agitator M of the present invention, the upper end of the rotating shaft 1 is attached to the mounting part 7 of the motor casing 6 equipped with the handle 5, and as shown in FIG. The liquid is stirred by inserting it into the liquid filled in the container 8, starting the motor to rotate the rotary shaft 1 at high speed, and moving the agitator M as a whole below -H or in the left-right direction.

The details are shown in FIG.

In other words, when the rotating shaft 1 is held in a fixed position and rotated, each frame 2 rotates together with the rotating shaft 1 at the same circumferential position, and there is a gap between the intermediate parts of each frame 2. A three-dimensional annular contour C is formed, and the negative part of the liquid is confined inside this contour C.

Each frame 2 has a horizontal portion 2B at the upper edge inclined in the direction of inclination, a horizontal portion 2C at the lower edge inclined in the downward direction, and a vertical portion 2D at the outer edge inclined in the diameter reduction direction. By rotation, liquid is received from the outside of the contour C along the vertical part 2D,
Moreover, the liquid within the contour C is sent out to the outside along the upper and lower horizontal portions 2B and 2C.

Therefore, even when the stirrer M is stationary, this contour C
Liquid flows inside and outside, and the liquid sent into the contour C is kneaded by mutual interference and frictional resistance due to the vortex generated inside the contour C, and when flowing into and out of the contour C, the edge of the frame 2 The granules are impacted by the edge and are agitated, resulting in uniform agitation.

Next, when this stirrer M is moved vertically or horizontally in the liquid, the liquid is forced to flow in and out of the contour C, and the liquid confined within the contour C and the liquid outside are more rapidly separated. They mutually interfere with each other and are rapidly agitated, resulting in uniform mixing in a short period of time.

In addition, by setting the inclination directions of the horizontal parts 2B, 2C and the vertical part 2D of the frame 2, it is configured such that fluid is received within the contour C from above and below the frame 2 and discharged from the vertical part 2D. If a frame body 2 is provided around the cylindrical body 4 attached to the rotating shaft 1 as shown in FIG.
The direction of inclination of the frame can be easily reversed by reversing the mounting direction of the frame body up and down and mounting it around the rotating shaft 1.

In this case, as described above, the frame bodies 2 having sides inclined in the direction of rotation are attached to the rotary shaft 1, and the hollow part 2A of each frame body 2 is Ir1.
1 By rotating the rotation axis 1 in a direction that crosses the plane including the axis, the liquid flows inside and outside the three-dimensional contour C formed by the rotation of the frame 2, and the viscosity of the liquid is actively reduced. Sufficient kneading and agitation is achieved by mutual interference and friction between the liquids, and when the liquid flows into and out of the contour C, particles or particles contained in the liquid are removed at the edge of each frame 2. Things can be destroyed and mixed uniformly,
Furthermore, by moving the entire stirrer vertically and horizontally, the fluid flows more rapidly into the contour C, and the liquid can be completely stirred in a short time.

Furthermore, in the present invention, since the outer edge of the frame 2 is vertical, the agitator M can be brought close to the inner wall of the container 8, and the liquid can be sufficiently agitated at the corner.

As mentioned above, the present invention does not only stir on a flat surface like the conventional propeller-type or cutter-type stirring blades, but also sufficiently stirs within a three-dimensional contour, so the stirring effect is improved compared to the conventional one. It can be improved dramatically.

The present invention has the effect that it can be used for stirring any liquid because it does not increase the temperature of the liquid due to stirring.
