In the above-mentioned conventional stirrer, the hand-held motor must be directly supported by hand and used to swing, so that the burden on the worker during use becomes large. In view of the above, an object of the present invention is to solve such a problem.

[0005]

In order to achieve the above object, a portable stirrer according to the present invention, as described in claim 1, comprises a rotary drive base for supporting and rotating a container, A support base having a support member is formed, and a stirring motor is provided at the tip of an arm mounted swingably and overhanging on the upright support, and a vertical rotation is provided on the output shaft of the motor. The shafts are connected, and a disk member is rotatably mounted on an upper portion of the vertical rotation shaft, and a stirring member having a smaller diameter than the disk member is fixed on a lower portion.

When using this stirrer, a container containing the liquid to be stirred is placed on a rotary drive table and rotated relatively slowly, while the stirring member is immersed in the liquid and the disk member is placed above the liquid surface. The stirring motor is rotated at an appropriate speed while being positioned below the upper edge of the container. The stirring member causes the liquid to flow in a specific direction, and the reaction force from the liquid accompanying the flow causes the stirring member to be displaced in a specific direction around the upright support member. It comes into contact with the inner surface, and this state is always maintained during rotation of the container. Therefore, the stirring member allows the liquid at a position appropriately distant from the inner surface to flow without contacting the inner surface of the container, thereby efficiently homogenizing the liquid.

The present invention is embodied as follows. That is,

It will be.

As described in claim 3, a plurality of agitating members are provided, and each agitating member is fixed at a different height position of the vertical rotation axis. By doing so, the widest possible range of the upper and lower ranges of the liquid to be stirred in the container can be simultaneously stirred, and the liquid to be stirred can be rapidly homogenized.

According to a fourth aspect of the present invention, the rotary drive table supports a container containing several tens of liters and rotates at a speed of several revolutions per minute to several tens of revolutions per minute. The height is set to correspond to the vicinity of the upper end of the inner side surface of the container. According to this, even when a large amount of the liquid to be treated is present in the container, the disk member operates without being immersed in the liquid to be stirred, and the stirring member removes the liquid to be treated during the stirring of the liquid to be stirred. Operates without excessive ripples,
The liquid to be treated is stably stirred.

[0010] Further, the agitating motor is an air motor, and the rotary drive base is rotatably driven by the air motor. By doing so, the motor does not generate spark, and even if the liquid to be stirred contains a highly flammable liquid such as thinner, it is stirred without fear of explosive combustion due to the spark.

Denotes an air motor that rotates the rotary drive base 3 at a speed of several rotations per minute to several tens of rotations per minute.

Reference numeral 8 denotes an arm mounted on the upper part of the upright support member 4 so as to be swingable and projecting.
A stirring motor 9 is provided at the tip of the. At this time, the arm portion 8 is attached to the small-diameter portion 4b of the upright support member 4 so as to be detachably externally attached thereto, and is mounted on the outer peripheral surface of the rectangular tube member 10 so that the length of the lateral extension can be adjusted. The two overhanging support rods 11a, 11b
1b, and has a vertical end cylindrical member 12 into which the output portion c1 of the main body frame of the stirring motor 9 is inserted.

The stirring motor 9 is an air motor having a horizontal handle c2.
It rotates at a higher speed than, for example, several tens of revolutions per minute. An air hose 13 is connected to the handle c2 via a speed controller.

Reference numeral 14 denotes a downward output shaft 9a of the stirring motor 9.
Is a vertical rotation shaft coupled to the vertical rotation shaft 14 via a joint fitting 15.
A disk member 16 of about 0 cm is rotatably mounted via a ball bearing, and the disk member 16 is provided at three lower positions.
A circular stirring member 17 slightly smaller in diameter than the above is fixed concentrically.

At this time, the disk member 16 may be a single member or a plurality of members other than three.
Alternatively, the height of each stirring member 17 can be changed or the stirring member 17 can be detached. Each of the stirring members 17 has a large number of protruding pieces 17a formed around the disk, and the protruding pieces 17a are alternately bent approximately 90 degrees up and down. However, the present invention is not limited to this, and may be arbitrarily deformed such as a propeller-shaped one.

The product of the present invention is to be carried and used at the site of use, and an example of use and operation in the case where the product of the present invention is used for stirring a coating liquid in a canister will be described. The user leaves the stirring member 17 out of the range of the upper surface of the rotary drive base 3 as shown in FIG. 1, and places the can on the rotary drive base 3 after the upper plate is cut off and opened. I do. In this mounting, the edge 5 is located outside the lower edges of the four sides of the can and the position of the can a is specified, so that the user places the can a on the approximate position. By merely allowing it to fit inside the edge 5, the canister a will be in an accurately positioned state.

Next, the motor 9 is lifted up by holding the handle c2 of the air motor 9 for agitation, whereby the base-side rectangular tube member 10 is pulled out from the small-diameter portion 4b of the upright support member 4, and The arm 8, the stirring motor 9, the vertical rotation shaft 2, the disk member 16 and the stirring member 17 are displaced in the same shape. By this pulling-up operation, the lower end of the vertical rotation shaft 14 is raised higher than the canister a, and the stirring member 17 is moved into the coating liquid which is the liquid d to be stirred in the canister a.
The base square tube member 10 is extrapolated to the small diameter portion 4b of the upright support rod 4. Thus, the three stirring members 17 are located at the upper, middle, and lower depths in the coating liquid d, and the disk member 16 is moved from the surface of the coating liquid d on the inner surface of the canister a to the upper edge as shown in FIG. It is located at a specific height in the range up to.

Thereafter, the agitating motor 9 and the rotary drive table motor 7 are rotated, whereby the canister a is integrally formed with the rotary drive table 3 at a speed of several to several tens of rotations per minute. The stirring member 17 is rotated around the vertical rotation shaft 14 at a speed of about several tens of revolutions per minute.

When the stirring member 17 rotates, the coating liquid d flows in the rotation direction by the large number of projections 17a. At this time, the flow of the coating liquid d applies a displacement force in a specific direction to each stirring member 17. This displacement force causes the arm 8 to swing around the upper end of the upright support member 4. As a result, the outer peripheral edge of the disk member 16 is pressed against the inner surface of the canister a, and this pressed state is always maintained during rotation of the canister a about the vertical axis 2.

Accordingly, each of the stirring members 17 is a member that moves and stirs the surrounding coating liquid d while being repeatedly moved on a fixed orbit within the canister a.
Has a slightly smaller diameter than the disk member 16,
The projecting piece 17a moves in the vicinity of the inner surface of the canister a, and the coating liquid d present in the environment where it is relatively hard to flow exists.
Is effectively flowed, and the coating liquid d is homogenized quickly with less labor.

During the stirring of the coating liquid d, the evaporation component of the solvent such as a highly flammable thinner mixed into the coating liquid d may flow into the stirring motor 7 or the rotary drive stand motor 9. In such a case, these motors 7,
Since an air motor 9 does not generate a spark, an explosion and a fire caused by the motors 7 and 9 hardly occur. Note that, in the above-described embodiment, the case where stirring is performed by using the canister a as a container is described, but the present invention is not limited to this.

[0024]

According to the present invention, the following effects can be obtained. That is, according to the present invention, it is possible to rapidly homogenize the liquid in a can by stirring it in a labor-saving manner.

According to the second aspect of the present invention, the processing of immersing the stirring member or the like in the liquid to be stirred in the container or pulling the stirring member out of the liquid to be stirred can be performed by attaching or detaching the arm to or from the upright support member or by supporting the support member. This can be performed more conveniently by attaching and detaching to and from the base.

According to the third aspect of the present invention, the liquid to be stirred can be rapidly homogenized by simultaneously stirring a portion of the liquid to be stirred which is as large as possible in the upper and lower ranges.

According to the fourth aspect of the present invention, the liquid to be treated can be stably stirred without excessively waving the liquid to be treated while a large amount of the liquid to be treated is present in the container.

According to the fifth aspect, even if the liquid to be stirred contains a highly flammable liquid such as thinner, the liquid can be stirred without fear of ignition and combustion.
