[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mixing and stirring chemical substances, chemicals and the like into a solution or mixing and stirring a solution with another solution by using a stirrer such as a magnetic stirrer.

[0002]

2. Description of the Related Art Magnetic stirrers are used for stirring solutions in chemical experiments, chemical devices, chemical plants and the like. Especially, it is necessary for agitation of small-scale solutions, and it is also used in some manufacturing plants. The large stirrer has various problems such as trouble of the stirrer shaft, contamination of the gland packing, and heat of rotation of the gland part.

In the case of a magnetic or stirrer, the above-mentioned trouble does not occur, but it is necessary to set a Teflon stirring rotor (3) inside the container (2), and the shape of the rotor depends on the application, such as a round bar. It is a square rod, a circle, a triangle, a gear, a concave-convex disc, etc., and weighs 1 to 100 g.

[0004]

When a horseshoe-shaped magnet (2a) is rotated by an internal motor, a magnetic or stirrer is a Teflon rotor set in the lower center of a glass container (4) placed on the upper part. The solution is stirred by the induction rotation of (3), the viscosity of the solution is changed by the concentration change, the temperature change, etc. of the stirring, and the "gas" is mixed by the stirring and the swirl is generated. In (3), the movement becomes non-uniform, and the glass container may be blown out by the centrifugal force from the central part, or the rotation may be stopped by the movement of the Teflon rotor (3),
In the case of a chemical reaction, etc., it becomes a problem with temperature rise.Generally, in the case of magnetic or stirrer, a glass container is used to observe the changing state of the solution, and although it responds to the change of the solution, manpower is insufficient. On the other hand, when the glass container (4) is destroyed due to runaway of the Teflon rotor (3) due to changes in solution viscosity during unattended operation, the solution flows out and sparks on the motor brush part of the magnetic stirrer. Ignited,
If there is a fire or if you are also using a water bath,
When the effluent solution reacts and explodes, it may cause a serious accident due to burning of the adjacent equipment due to ignition and explosion.

Magnetic and stirrers have great characteristics as solution mixing regulators, but on the other hand, the shape of the rotor and the magnetic and stirrer themselves have been improved, but the Teflon rotor (3 There are still many problems of glass container damage caused by runaway. It is an object of the present invention to provide a rotor safety ring (1) for stirring, in which the Teflon rotor (3) normally rotates even when the solution is changed to stir the solution.

[0006]

As a solution to the problem, the present invention sets a Teflon rotor (3) in a glass container (4) even when the solution viscosity of the Teflon rotor (3) changes. In order for the Teflon rotor (3) to operate normally, a ring is provided to fix the Teflon rotor (3) so that it does not fly off the center of the container (4). The diameter of the ring is larger than that of the Teflon rotor (3). Inside, the Teflon rotor (3) is a ring with a diameter sufficient to rotate and this ring is fixed to the center of the glass container. By fixing to the lower part, the Teflon rotor (3) does not move by rotation, and problems associated with breakage of the glass container and stirring of the solution are solved.

[0007]

Next, the operation will be described with reference to FIG. The horseshoe magnet (2a) rotates with the rotation of the motor (2c) inside the magnetic stirrer (2), and the Teflon rotor (3) set at the center bottom of the container (4) rotates by induction.
There is a problem that the Teflon rotor (3) runs out of control by stirring the solution (5) in the past, so it is running inside the stirring rotor safety ring (1) of the present invention. , The glass container (1) containing the solution is not damaged, and the accident accompanying this is also eliminated, and the Teflon rotor (3) rotates stably.

1 is a perspective view of a stirring rotor safety ring (1) according to an embodiment of the present invention. The thickness of this ring is 0.
5mm-5mm, the diameter of the ring is 20-200mm
The width is 5 to 100 mm, the material is Teflon,
A polymer material made of polycarbonate, nylon, polyethylene, polyester, etc., or molded with copper, aluminum, brass, etc. and coated with the above resin, and the ring (1) and the support (6) are made of the same material as the above and have a diameter of 2 30 mm
Then, the length was set to a ring so that it could be set to the inner diameter of the container (4).

FIG. 2 shows an internal horseshoe-shaped magnet (2a) of a magnetic or stirrer according to the overall construction of the embodiment of the present invention.
The motor (2c) is built under it, the "Separa" glass container (4) is placed on the upper part of the magnetic stirrer, and the stirring rotor safety ring (1a) of the present invention is set inside the glass container (4a). The Teflon rotor (3) is placed in the center, the solution (5) is magnetic, and the motor (2c) of the stirrer is operated to rotate the horseshoe magnet (2a) to rotate the Teflon rotor (3) in the container (4). ) Inducing rotation of the rotor stirs the solution by stirring (1
a) and the same column (6a), the glass container is different in size from the separa container and the beaker container, so the safety ring (1) has two to three pairs of columns with different lengths, and a ring is formed at one end of the making column. To attach to, cut the screw, rotate the screw to adjust the length and set it at the bottom of the container.

The fixing of the support pillar (6) of the rotor safety ring (1) shown in FIGS. 1 to 5 can be adjusted by screwing to adjust the length to match the inner diameter of the container. Attach the spring to the fixed part of the ring support (6a) and set it to support the support (6a).
It is also possible to give elasticity to the container to facilitate setting in the container (4).

[0011]

According to the present invention, the Teflon rotor (3) of the glass container is fully placed in the ring of the stirring rotor safety ring (1a) of the present invention, by fully exerting the effects of magnetic and stirrer. Since it is rotated, the conventional glass container is not damaged by runaway, unattended stirring of the solution is possible and efficiency is improved, and the danger of continuous operation day and night is eliminated, and safety can be secured.
