BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirrer capable of rotating a granular material such as ceramic particles in a container.

[0002]

2. Description of the Related Art In recent years, in the treatment of garbage, a method has been adopted in which ceramic particles mixed with microorganisms are rotated in a container, and the garbage is put into the container, and the garbage is fermented to be eliminated by good stirring contact with the microorganisms. Have been.

Heretofore, as a means for rotating ceramic particles mixed with the above microorganisms in a container, a horizontally rotating wing piece has been installed at the bottom of the container.

[0004]

However, when the wings are provided at the bottom of the container as described above, not only a loud noise is generated due to direct contact with the ceramic grains, but also a large noise is generated.
Stirring properties differ greatly between the part close to the wing piece and the part far from it,
There was a problem that the whole could not be stirred evenly.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a stirrer capable of rotating a granular material such as ceramic particles in a container only by vibration applied to the container. And

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an object-to-be-stirred container having at least a bottom formed in an arc shape, and two parts of the object-to-be-agitated object that are separated from each other in an arc direction. And a vibration generator that applies vibration to the support, and a grounding leg that absorbs the vibration of the support, wherein the vibration generated by the vibration generator is transmitted through the support. Thus, the container is efficiently provided with a propulsive force in a certain direction to the object to be agitated, and this is used as a power source to generate the necessary rotational movement of the object to be agitated.

Further, the invention according to claim 3 is characterized in that the vibration generator is provided with a turning weight, and the vibration itself is configured to generate a kinetic force directed in a certain direction.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side cross-sectional view of the stirring device of the present invention schematically showing a state in which an object to be stirred undergoes rotational motion due to vibration, and FIG. 2 is a front cross-sectional view of the stirring device of the present application.

The stirring device 1 of the present application includes
A supporting table 3 for the container 2 to be stirred; a vibration generator 4 for applying vibration to the supporting table 3; and a grounding leg 5 for absorbing the vibration of the supporting table 3. 6 is a base.

[0011] As shown in FIG.
At least the bottom 2a is formed in an arc shape, and a lid 2b is provided in the upper opening. The reason why the bottom 2a is formed in an arc shape is that it is effective for applying a smooth propulsion force in the arc direction to the ceramic particles 7 charged into the container by the vibration described later. In this sense, the stirrer charging container 2
May be entirely cylindrical.

The propulsion force for the ceramic particles 7 can be further improved by reducing the contact area between the inner surface of the container 2 and the ceramic particles 7. Therefore, in this embodiment, the ribs 2 c along the arc direction are formed on the inner surface of the container 2. Are provided in multiple articles.

The rib 2c may be formed by fixing a linear object such as a wire to the inner surface of the container 2 by welding or the like, or may be formed as a ridge on the inner surface of the container 2. Further, when the ribs 2c are arranged in a spiral shape, the rotating motion in the arc direction and the moving force in the axial direction are simultaneously applied to the ceramic grains 7, which is effective in that the stirring properties can be further improved.

Further, the inner surface of the container 2 may of course be embossed for the purpose of obtaining a good propulsive force by reducing the contact area between the inner surface of the container 2 to be stirred and the ceramic grains 7. is there.

In the example shown in the drawing, the support base 3 has a side-to-side shape, and its upper edges 3a and 3b support two points A and B separated from each other in the arc direction of the container 2 to be stirred. The shape of the support 3 and the support points A and B are not particularly limited.

The vibration generator 4 is mounted on the bottom 3 of the support 3.
c. The vibration generator 4 may use a repulsion of an electromagnet, but in the illustrated example, a vibration generator 4 having an eccentric weight 4c fixed to a thrust shaft 4b of a built-in motor 4a is used. Of course, any other mechanical structure may be used.

Although a general commercially available vibration generator 4 is satisfactory, it is preferable that the output, frequency and amplitude of the vibration generator 4 be variable by a hand controller (not shown).

The grounding leg 5 is formed of a helical spring material fixed to four corners on the lower surface of the bottom 3c of the support 3 and is fixed to the base 6. That is, most of the energy of the vibration generated by the vibration generator 4 is applied to the object charging container 2 and the ceramic particles 7 in the container via the support table 3, and is not transmitted to the base 6. ing.

The vibration generator 4 is provided with a timer (not shown) that is driven and stopped at regular intervals depending on the application of the stirring device 1 of the present invention. Then, for example, it is possible to control such that the motor is driven for 5 minutes every 60 minutes.

Further, in consideration of the case where the stirring apparatus 1 of the present invention is used for garbage disposal, a hot plate (not shown) is installed at an appropriate position of the container 2 to be stirred, and microorganisms mixed with the ceramic particles are actively activated. In some cases, it is possible to secure the room temperature at which people can perform activities.

In the above-described embodiment, first, ceramic particles 7 mixed with microorganisms in advance are charged into the container 2 for charging an object to be stirred as a carrier. It is preferable that the input amount is approximately half of the volume of the container.

Next, when the vibration generator 4 is energized and the built-in motor 4a is driven, the eccentric weight 4c fixed to the thrust shaft 4b rotates. As a result, vibration is generated, and the vibration
A of the container 2 to be agitated through the upper edges 3a and 3b,
Although transmitted to point B, the transmission is slightly delayed such that point A is earlier and point B is delayed. The same direction as the direction 4c 'in which the weight 4c rotates (the direction of the arrow a =
A counterclockwise thrust will be generated.

The propulsion force of the ceramic particles 7 in the direction of arrow a is greatest at the portion in contact with the arc-shaped inner bottom surface of the container 2 to be agitated, and the portion overlapping therewith is also dragged and moved. Arrow b on the front arc surface and vertical wall
Ascend. Then, it reaches the ascending point c and flows naturally along an inclined surface as indicated by an arrow d, and reaches the opposite wall side again to obtain the propulsive force in the direction of the arrow a.

As described above, as long as the vibration generated by the vibration generator 4 continues, the ceramic particles 7 repeat the above-mentioned semi-lunar closed-loop movement in the container 2 to be stirred. The rotation speed at this time is determined by an output, a frequency, and an amplitude adjusted by a hand controller (not shown) of the vibration generator 4.

Now, if garbage (not shown) is thrown into the ceramic particles 7 of the container 2 to be stirred, the garbage performs the above-mentioned semi-lunar closed-loop movement together with the ceramic particles 7 to ensure reliable and efficient operation. It is stirred well and evenly, and fermented over time with sufficient contact with microorganisms to disappear.

In the above embodiment, the stirring device 1 of the present invention is used.
Has been described as an example in which the present invention is applied to a stirrer for processing garbage, but it is needless to say that the present invention can also be used as a sand remover for bivalves such as clams or a rice washing machine.
