Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirrer that vibrates and stirs a bed of sawdust containing fermentative bacteria, for example, to fermentatively destroy garbage.

[0002]

2. Description of the Related Art In recent years, in the processing of garbage, sawdust containing fermenting bacteria has been used as a bacterial bed, agitated in a container, and the garbage has been put into the garbage and mixed with the fermenting bacteria to produce garbage. Methods (apparatus) for fermentation and extinction have been developed.

Conventionally, as a means for stirring a bed of sawdust or the like containing the above fermentation bacteria in a container, a rotor blade is usually installed at the inner bottom of the container, and the rotor blade is rotated by an external drive. However, if garbage contains foreign objects such as knives or spoons, there is a problem in that it may come into contact with the rotor blades and generate loud noises, or the foreign objects may damage the rotor blades or containers. However, in the case of the rotary wing piece, the stirring properties differ between the part near and far from the wing piece, so that the whole cannot be agitated uniformly, and the reach of the rotary wing piece is constant and the There is also a problem that blind spots are formed, and bacteria beds such as sawdust and a part of garbage are stagnated.

[0004] Therefore, the present inventor has proposed a stirrer capable of imparting a necessary rotational movement force (stirring force) to the contents without first installing a rotary blade piece. The stirrer according to this proposal holds a container having an inner bottom surface in a semicircular arc on a support base via an elastic material, and applies a vibration from a vibration generator to the container to convert a bacterial bed such as sawdust into the container. We succeeded in rotating and moving along a semicircular arc.

[0005]

However, the above-described stirring device using vibration is extremely excellent in stirring property as described above, but lacks the crushing property (function as a crusher) of large garbage to be charged. Therefore, in order to expedite the processing, there is a problem that it is necessary to crush the garbage to a certain size before putting the garbage.

An object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a novel stirring device which is excellent in crushability while being a stirring device by vibration.

[0007]

In order to achieve the above object, the present invention provides a container having a semi-circular inner bottom surface or an inner bottom surface having a plurality of semi-circular arcs continuously formed in the diameter direction.
A support base holding the container via an elastic material, and a vibration generator for applying vibration to the container, wherein a projection piece is installed at an appropriate position on or near the inner bottom surface of the container, Vibration from the generator was applied to the container so that large garbage could be crushed while rotating and moving the garbage together with a bed of sawdust and the like.

According to a second aspect of the present invention, the protrusion is provided on the side of an entrance to the inner bottom surface of the object to be stirred which rotates in the container. Thus, the crushing efficiency of the garbage can be increased without impairing the bacterial bed and the rotational mobility of the garbage.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front sectional view schematically showing the stirring device of the present application, FIG. 2 is a side view of the stirring device of the present application, FIG. 3 is a cross-sectional perspective view of a container schematically showing the installation position of the projecting piece, FIG. Is a perspective view of a projection piece.

[0010] The stirring device 1 of the present invention is a device in which a semi-circular
A container 2 having an inner bottom surface provided with two bottoms 2a and 2b which are continuous with each other, a support table 4 holding the container 2 via an elastic material 3, and a vibration generator 5 for applying vibration to the container 2 Consists of The elastic member 3 includes a flange piece 6 provided at the upper four corners of the container 2, and a support 7 erected from the four corners of the support base 4.
Is a coil spring interposed between them, but may be a leaf spring, a rubber material, or any other material as long as it has a buffering effect.

Although the inner bottom surface of the container 2 has two semicircular arcs and is provided with two bottoms 2a and 2b, a semicircular arc having only one bottom may be formed as a semicircular arc. Needless to say, three or more bases may be provided with three or more bases.

On both side walls 2 'and 2 "which are continuous with the inner bottom surface of the container 2, there are provided ribs 8 which are formed by extending the semicircular arc surface in an overhang shape. It serves as a guide when the object to be stirred (content) rotates.

In the illustrated example, the vibration generator 5 has an eccentric weight 5b fixed to a conical shaft 5a 'of a motor 5a.
3 shows the one utilizing the eccentric rotation of b. In addition, the vibration generator 5 is installed at the bottom of the container 2 in a hanging manner via an attachment frame 9 so that efficient vibrations including the own weight of the vibration generator 5 can be transmitted to the container 2.

In the above case, the motor 5a to which the eccentric weight 5b is fixed is installed such that the conical shaft 5a 'is located at the center of the bottom of the container 2. Thereby, for example, when the eccentric weight 5b is turned clockwise, the main vibration generated by this rotation is
It is transmitted to the left chamber L of the container 2 and the object to be stirred in the left chamber L
The secondary vibration is transmitted to the right ventricle R while applying a rotational force in the right direction.

The object to be stirred in the right chamber R to which the secondary vibration is transmitted is basically given a rotational force in the direction A 'in the same direction as the direction A, but the object to be stirred in the left chamber L is It has been experimentally confirmed that the rotational force in the direction B is strongly affected by the rotational force in the direction A. In other words, by rotating the eccentric weight 5b clockwise, the object to be stirred in the left chamber L has a rotational force in the direction A, and the object to be stirred in the right chamber R has mainly B force.
Direction rotational force will be applied.

On the other hand, when the rotation direction of the eccentric weight 5b of the vibration generator 5 is set to the counterclockwise direction, the main vibration generated by this rotation is transmitted to the right chamber R of the container 2, and the secondary vibration is The operation is transmitted to the chamber L, and the above operation is reversed. Therefore,
By adjusting the rotation direction of the eccentric weight 5b, the main rotation direction of the object to be stirred in the container 2 can be arbitrarily changed.

The rotation direction of the eccentric weight of the vibration generator 5 can be switched by a hand controller (not shown) or by a timer (not shown) at regular intervals. Good. The vibration generator 5 may be of another configuration, for example, utilizing the repulsion of an electromagnet, by devising how the vibration is transmitted to the container 2.

Two bottoms 2a, 2b of the inner bottom surface of the container 2
As shown in FIG. 1, near the top of the boundary rib 10 that branches
The protruding pieces 11 are installed back to back. This bottom 2a
The installation position of the side projection piece 11 is such that the agitated object rotating in the left chamber L due to the main vibration generated when the eccentric weight 5b of the vibration generator 5 is turned clockwise enters the inner bottom surface. Equivalent to a road. In other words, it can be said that this is a location where the rotating and moving object is urged downward, and is a location suitable for crushing large garbage caught on the projection 11. Of course, it is not limited only to this position.

The protruding piece 11 on the bottom 2b side has an object to be stirred which is rotated and moved in the right chamber R by the main vibration generated when the eccentric weight 5b of the vibration generator 5 is turned counterclockwise. Needless to say, this is equivalent to an approach path for approaching the bottom surface.

In FIG. 3, the projecting piece 11 is
There are four of them, two each near the top of 0, but 3
Six units may be installed for each unit. Of course, we do not care about this number of installations.

As shown in FIG. 4, the protruding piece 11 uses an L-shaped bracket (made of steel), one end 11a of which is sharpened, and the other 11b is provided with a mounting hole 11c. Although the structure is such that screws can be used, other structures may be used.

In the agitator 1 of the present invention shown in the above embodiment, first, a bed of sawdust containing fermentation bacteria, for example, about 70% of the volume of the vessel 2 is charged into the vessel 2 in advance. Next, the vibration generator 5 is operated such that the eccentric weight is clockwise. The main vibration generated by this imparts a rotational force in the direction A to the object to be stirred in the left chamber L of the container 2, while imparting a rotational force in the direction B to the object to be stirred in the right chamber R by secondary vibration. . The object to be stirred in the left chamber L that is rotating in the direction A by receiving the main vibration exhibits an appearance like a roller-shaped mass and stably rotates.

The inside of the bacterial bed in the left chamber L that is rotating stably in this manner is at a temperature condition (40 ° C. or higher) at which fermentation bacteria are easily activated.
It has become. Therefore, the garbage taken into the fungal bed is fermented and disappears in a short time, but the garbage is caught and broken by the protruding pieces 11 during the rotation, so that the garbage is fermented and disappears in a shorter time. It will be.

[0024] The rotary stirring movement of the object to be stirred is performed only by vibration and does not use a rotary blade piece. Therefore, even if foreign matter such as a knife or a spoon is contained in the garbage, a loud noise is generated. There is no problem such as generation or damage to the container by foreign matter, and the whole can be agitated uniformly. In addition, unlike the case where the rotor blades are agitated with power, there is no blind spot in the container,
There is no stagnation of some sawdust and garbage. Since the projection 11 fixed to the inner bottom surface of the container 2 does not rotate by itself, there is no problem even if foreign matter such as a knife or a spoon is contained in the garbage. Completely different from a piece.

[0025]

As described above, the present invention provides a container having a semi-circular inner bottom surface or an inner bottom surface having a shape in which a plurality of semi-circular arcs are continuously formed in the diameter direction, and holding the container via an elastic material. And a vibration generator that imparts vibration to the container, wherein the projections are provided at appropriate locations on or near the inner bottom surface of the container. , Large garbage can be crushed while rotating and moving the garbage together with the bacterial bed such as sawdust. Therefore, the present invention has an excellent effect that it is possible to generally provide a stirrer which is excellent in crushability while being a stirrer by vibration.

Further, the invention according to claim 2 is characterized in that the projecting piece is installed on the side of the entrance to the inner bottom surface of the object to be stirred which rotates in the container.
There is an excellent effect that the crushing efficiency of the garbage can be increased without impairing the rotational movement of the bacteria bed and the garbage due to the installation of the projection pieces.
