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 sawdust containing fermentative bacteria, for example, in order to fermentatively destroy garbage.

[0002]

2. Description of the Related Art In recent years, in the treatment of garbage, a method (apparatus) of stirring and moving sawdust containing a fermenting bacterium in a container, charging the garbage into the garbage and mixing and contacting the garbage with the fermenting bacterium is used. ) Is being developed.

Conventionally, as means for stirring sawdust containing the above-mentioned 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 at regular intervals. I was letting it.

[0004]

However, when the rotor blades are installed on the inner bottom of the container as described above, if foreign matter such as a knife or a spoon is contained in the garbage, the rotor blades come into contact with the rotor blades. Not only generated a loud sound,
There is a problem that the rotor blades and the container are damaged by foreign matter.
Further, in the case of a rotary wing piece, the stirring properties are different between a portion close to the wing piece and a portion far from the wing piece, so that the whole cannot be agitated evenly, and the reach of the rotary wing piece is constant, so that There was also a problem that blind spots were formed, and this caused some of the sawdust and garbage to stagnate.

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 agitator capable of providing a necessary agitation force to contents without installing a rotary blade piece. I have.

[0006]

According to the present invention, a container having an inner bottom surface having a shape in which a plurality of semicircular arcs are continuously formed in a diameter direction is held on a support base via an elastic material. A vibration generator is installed below the center of the bottom of the container, so that efficient vibration including the weight of the vibration generator can be transmitted to the container, and the vibration allows the object to be stirred (the contents ) Can be divided and rotated (stirred) for each continuous number of semicircular arcs.

According to a second aspect of the present invention, the vibration generator includes a motor having a penetrating shaft in a penetrating shape and an eccentric weight fixed to the conical shaft. The feature is that the axial direction is matched, efficiently generating vibration,
The system was designed to reduce noise.

Further, the invention according to claim 3 is characterized in that the vibration generator is capable of switching the rotation direction of the eccentric weight, and the main rotation direction of the divided rotating object can be arbitrarily changed. It was configured as follows.

[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, and FIG. 2 is a side view of the stirring device of the present application.

The agitator 1 of the present application comprises a vessel 2 held on a support 3 via an elastic material 4 and a vibration generator 6 installed below a center of the bottom of the vessel 2 via a mounting frame 5. The elastic material 4 used here is a flange piece 2a provided at the upper four corners of the container 2.
And a support 3a erected from the four corners of the support 3. Although a coil spring is shown as the elastic member 4 in the drawing, a leaf spring, a rubber material, or another material may be used as long as it has a buffering effect.

The inner bottom surface of the container 2 has a shape in which two semicircular arcs E are continuous in the diameter direction, but is not limited to two (three or more may be provided). The container 2
A rib 7 having a shape in which the arc surface of the semicircular arc E is extended in an overhang shape is provided on both end walls 2 'and 2 "in the continuous direction of the semicircular arc E
Is provided. The rib 7 serves as a guide when the object to be stirred (content) rotates.

The reason why the vibration generator 6 is installed below the bottom of the container 2 via the mounting frame 5 is to enable efficient transmission of vibration including its own weight to the container 2. In the illustrated example, the vibration generator 6 has a conical shaft 6 in a penetrating shape.
a) and an eccentric weight 6b fixed to the conical shaft 6a '. Further, the conical shaft 6a' and the semicircular arc E have the same axial direction. That is, as shown in the drawing, when the semicircular arc E is double, the conical axis 6a 'is located on the boundary line (when the semicircular arc E is triple, immediately below the central semicircular arc). By doing so, the eccentric weight 6 fixed to the conical shaft 6a '
Vibration generated by the rotation of b can be efficiently transmitted to the entire area of the container 2 through the mounting frame 5. Note that the vibration generator 6 is not limited to the above-described structure, and it is a matter of course that the vibration generator 6 may use a repulsion of an electromagnet.

As described above, the vibration generator 6 has its conical shaft 6
When a ′ is mounted at the above-described position, the vibration generated by the eccentric weight 6b turning clockwise transmits the main vibration to the left chamber L of the container 2 and the agitated portion in the left chamber L A main rotational force A is applied to an object (content). On the other hand, the secondary vibration is transmitted to the right chamber R, and the object to be stirred (contents) in the right chamber R is given a rotational force A 'basically in the same direction as the rotational force A. It has been experimentally confirmed that a rotational force B in a different direction is applied under the influence of the rotational force A of the contents in the inside.

In other words, by rotating the eccentric weight 6b of the vibration generator 6 forward or reverse, the main rotating direction of the object to be stirred (content) in the container 2 can be changed arbitrarily. The switching of the rotation direction of the eccentric weight of the vibration generator 6 may be performed by a hand controller (not shown) or may be performed at regular intervals by a timer (not shown). Note that the hand controller can be equipped with a variable function for increasing or decreasing the frequency.

Although the stirring device 1 of the present invention is not shown in the above embodiment, a hot plate (not shown) may be installed at an appropriate position of the container 2 if necessary in order to secure a temperature at which the fermentation bacteria can be actively activated. Is also good. Further, in order to further increase the propulsive force on the object to be stirred (contents), a rib may be provided on the inner surface of the container 2 along an arc direction, or a linear object such as a wire may be fixed by welding or the like.

In the stirring apparatus 1 of the present invention shown in the above embodiment, first, an object to be stirred (a sawdust or a ceramic particle containing a fermentation bacterium) serving as a carrier is charged into the container 2 in advance. It is preferable that the input amount is approximately 70% of the volume of the container 2.

Next, the vibration generator 6 is operated. As a result, if the eccentric weight rotates, for example, in a clockwise direction, and the vibration is generated, the vibration applies the main rotational force A to the object to be agitated in the left chamber L of the container 2 and the vibration in the right chamber R. A rotating force A 'is given to the object to be stirred by the secondary vibration, but the object to be stirred in the left chamber L receives the rotating force B under the influence of the main rotating force A. The object to be stirred in the left chamber L, which is rotating by receiving the main rotational force A, is stably rotated so as to have an appearance like a roller-shaped mass.

The container 2 rotates by receiving a main rotational force A of the object to be stirred in the left chamber L and a rotational force B in the right chamber R. When garbage (not shown) is thrown into sawdust (or ceramic grains) containing the fermenting bacteria rotating in this manner, the agitated material in the left chamber L rotating under the main rotational force A is received. Since the material is rotating stably as described above, the inside is under a temperature condition (40 ° C. or higher) at which the fermentation bacteria are easily activated. Therefore, the garbage taken into this will be fermented and disappear in a short time.

As described above, as long as the vibration generated by the vibration generator 6 continues, the object to be stirred repeats the above operation in the container 2. Further, the rotation direction is exchanged as needed by a timer. At this time, the rotation speed, the vibration frequency, and the like are determined by a hand controller (not shown) of the vibration generator 6.

[0020] The rotary stirring motion of the above contents is performed only by vibration and does not use a rotary wing piece, so that a loud noise is generated even when foreign matter such as a knife or a spoon is contained in the garbage. There is no problem of causing the container to be damaged by the foreign matter or the foreign matter, and the whole can be stirred uniformly. In addition, unlike the case where stirring is performed by using the rotor blades as power, there is no blind spot in the container, and there is no stagnation of waste or part of garbage.

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.

[0022]

As described above, according to the present invention, a container having an inner bottom surface having a shape in which a plurality of semicircular arcs are continuously formed in a diametrical direction is held on a support base via an elastic material, and the container is disposed below the center of the bottom of the container. It is characterized by the installation of a vibration generator, so that efficient vibration including its own weight can be transmitted to the container, and the vibration causes the object to be stirred (content) in the container to be continuous An excellent effect of being able to be rotated (stirred) every time is obtained.

According to a second aspect of the present invention, the vibration generator comprises a motor having a penetrating shaft in a penetrating manner, and an eccentric weight fixed to the conical shaft. Since the axial directions are matched, an excellent effect of efficiently generating vibration and reducing noise is achieved.

Furthermore, the invention according to claim 3 is characterized in that the vibration generator is capable of switching the rotation direction of the eccentric weight, so that the main rotation direction of the object to be divided and rotated can be arbitrarily set. It has an excellent effect that it can be changed.
