Technical field

The present invention relates to a stirrer for stirring a bed of bacteria such as sawdust containing a fermentative bacterium by vibration, for example, in order to eliminate garbage by fermentation. Technology background

In recent years, in the processing of garbage, a bed of oakakuzu or the like containing germ-killing bacteria has been stirred and moved in a container, and garbage has been added to the garbage and mixed with germ-free bacteria to make the garbage germ-free and disappear. Methods (equipment) have been developed. As means for stirring the sawdust containing the above-mentioned germ-proof yeast in a container, a rotor blade was usually installed at the inner bottom of the container, and the rotor blade was rotated at regular intervals by an external drive.

However, when the rotor blades are installed on the inner bottom of the container as described above, if foreign objects such as knives or spoons are contained in the garbage, they not only make contact with the rotor blades but generate loud noises, There was a problem in that foreign matter could damage the rotor blade container. In addition, 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 stirred evenly, and the reach of the rotary wing piece is constant, so that There was also a problem in that a blind spot was formed in this area, and a part of the bacteria bed such as sawdust and garbage were stagnated.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a novel stirring device that can provide a necessary stirring force to contents without installing a rotary blade piece. Disclosure of the invention

The present invention provides a stirrer charging container having a shape in which a plurality of semicircular arcs are continuously formed in the diameter direction at the bottom. W

2 is held on a support base via an elastic material, and a vibration generator is hung below the center of the bottom of the container. The vibration of the vibration generator, including the weight of the vibration generator itself, In addition to being transmitted to the container, the vibration causes the object to be agitated (contents) in the container not only to be divided and rotated (stirred) for each continuous semicircular arc, but also for the direction of rotation to be controlled by the vibration generator. It was configured such that a high agitation force could be obtained by performing the replacement only with the appropriate time. The invention according to claim 2 is characterized in that a stirrer charging container having at least a bottom formed in a single arc shape is held on a support base via an elastic material, and vibration is generated so that vibration can be applied to the container. It is characterized by the fact that the propulsion force in a certain direction can be applied to the agitated object (contents) in the container by the vibration of the vibration generator even if the bottom is a single arc, and this is used as a power source. The structure was such that a high stirring force was applied to the oil. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a front cross-sectional view of a stirrer according to a first embodiment of the present invention, in which a bottom of a container schematically shows a shape in which two semicircular arcs are continuous in a diameter direction, FIG. FIG. 3 is a front sectional view of a stirring device according to a second embodiment of the present invention in which the bottom of the container is a single semicircular arc, and FIG. 4 is a side sectional view of the same. BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described in more detail with reference to the accompanying drawings. The stirrer 1 according to the first embodiment of the present invention, as shown in FIG. 1 and FIG. 2, holds the container 2 to be stirred into the support base 3 via the elastic member 4, and The vibration generator 6 is suspended from the mounting frame 5. The elastic member 4 shown in FIG. 1 is interposed between a flange piece 2 a provided at the upper corner of the container 2 and a column 3 a erected from the four corners of the support base 3. The elastic member 4 shown in FIG. 3 is interposed between the vibration table 3 a ′ on which the vibration generator 6 is installed and the support table 3. In addition, although the coil spring is shown in the case of the illustration as the elastic member 4, a leaf spring, a rubber material, or other materials may be used as long as they have a buffering effect. The inner bottom surface of the container 2 shown in FIG. 1 has a shape in which two semicircular arcs E are continuous in the diameter direction, but the number is not limited to two. There may be three or more, and as shown in FIG. 3, the semicircular arc E may be singular. Further, in the case of the container 2 in which the semicircular arcs E are continuous, the ribs 7 are provided on both end walls 2 'and 2' in such a manner that the arc surfaces of the semicircular arcs E extend in an overhanging manner. The rib 7 serves as a guide when rotating the object to be stirred (content).

The reason why the vibration generator 6 is suspended below the bottom center of the container 2 via the mounting frame 5 is that the vibration including the weight of the vibration generator 6 itself can be efficiently transmitted to the container 2. That's why. In the example shown in the figure, the vibration generator 6 includes a motor 6a, a conical shaft 6a 'penetrating through the housing of the motor 6a, and an eccentric weight fixed to both ends of the conical shaft 6a'. In FIG. 1, the conical axis 6 a ′ coincides with the axial direction of the semicircular arc E and is located on the boundary of two semicircular arcs E (such as a single or triple semicircular arc). If it is odd, it will be just below the central semicircle. With this configuration, the vibration generated by the rotation of the eccentric weight 6 b fixed to both ends of the conical shaft 6 a ′ can be efficiently transmitted to the entire area of the container 2 through the mounting frame 5.

When the conical axis 6a 'of the vibration generator 6 is mounted at the above-described position, the vibration generated by the eccentric weight 6b turning clockwise turns mainly to the left chamber L of the container 2. Vibration is transmitted, and a main rotational force A is applied to the object (content) in the left chamber L. On the other hand, since the secondary vibration is transmitted to the right chamber R, a rotating force A 'in the same direction as the rotating force A is basically applied to the object to be stirred (contents) in the right chamber R. It has been experimentally confirmed that a rotational force B in a different direction is given in part due to the rotational force A of the contents in L.

In other words, by rotating the eccentric weight 6b of the vibration generator 6 forward or reverse, the main rotation 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). Increasing and decreasing the frequency and other variable functions can be installed. When the vibration generator 6 is installed on a vibration table 3a 'as shown in FIG. 3, the vibration generated by the rotation of the eccentric weight 6b of the vibration generator 6 is applied to points P and P' of the container 2. The eccentric weight 6b is transmitted through the rising wall 3a, and there is a slight time difference in the way of transmission depending on the rotation direction of the eccentric weight 6b, and this becomes the propulsive force for the object to be stirred. Of course, the propulsion force of the object to be stirred is repeated as long as the vibration of the vibration generator 6 continues. The structure of the vibration generator 6 is not limited to the above-described structure. For example, the vibration generator 6 may utilize a repulsion of an electromagnet.

The stirrer 1 according to the present embodiment is provided with a hot plate (not shown) at an appropriate place in the container 2 if necessary to secure a temperature at which the yeasts contained in the bacterial bed can be actively activated. May be placed. Also, in order to further increase the propulsive force against the object to be stirred (contents), ribs 8 are provided on the inner surface of the container 2 along the arc direction as shown in FIGS. 3 and 4, or a wire such as a wire is welded. It may be fixed by the like.

In the above-described embodiment, an object to be stirred (a sawdust or a ceramic particle containing a germ-proof bacterium) is previously charged into the container 2. This amount should be about 50 to 70% of the capacity of the container 2.

Next, the vibration generator 6 is operated. As a result, assuming that the eccentric weight causes vibration in FIG. 1 by rotating clockwise, for example, the vibration applies a main rotational force A to the object to be stirred in the left chamber L of the container 2, while The object to be stirred in the right chamber R is given a rotational force A ′ by the secondary vibration, but the object to be stirred in the left chamber L is partially affected by the main torque A and receives a torque B. The object to be stirred in the left chamber L, which is rotated by receiving the main rotational force A, rotates stably 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 of the container 2 and a rotational force B in the right chamber R. When garbage (not shown) is thrown into the sawdust (or ceramic grains) containing the spinning germ fungus, the left ventricle L, which is rotated by the main rotational force A The object to be stirred inside is rotating stably as described above, so the inside is under temperature conditions (40 ° C or higher) at which the germ-proof bacteria can easily be activated. Therefore, in this The garbage taken in will be extinguished in a short time.

As shown in FIG. 3, in the case of the container 2 having a single arc, the object to be stirred has a half-moon-like propulsion as shown by arrows S, S ′, and S〃. This propulsion is performed as long as the vibration generated by the vibration generator 6 continues, and stirs the object to be stirred in the container 2. In addition, the direction of rotation can be changed at any time depending on the time, and the rotation speed and frequency can be changed.

The above contents rotate and stir only by vibration and do not use rotary wings, so loud noise is generated even when foreign objects such as knives or spoons are contained in the garbage. However, there is no problem that the container is damaged by the foreign matter, and the whole can be uniformly stirred. Moreover, unlike the case of stirring using the rotor blades as power, there is no blind spot in the container, and there is no stagnation of bacteria bed such as sawdust and garbage.

Regardless of whether the bottom semicircular arc E is singular or plural, the bottom half is formed into a semicircular arc in the container 2 to be stirred by vibrating the object to be stirred into the container by vibrating. This is for providing smooth propulsion. In this sense, the object-to-be-stirred charging container 2 may be entirely a single or plural cylinders.

It is considered that the propulsion force for the object to be stirred is further improved by reducing the contact area between the inner surface of the container 2 and the object to be stirred, and a plurality of ribs extending along the arc direction are provided on the inner surface of the container 2 as described above. Alternatively, it may be formed as a ridge on the inner surface of the container 2 along the flow direction.

Further, from the viewpoint of obtaining a good propulsive force by reducing the contact area between the inner surface of the object to be stirred ^ 2 and the object to be stirred, it is of course possible to emboss the inner surface of the container 2 by δ volumes. ο

Although the vibration generator 6 is generally satisfactory as a commercially available one, it can also be provided with a timer (not shown) that is driven and stopped at regular intervals depending on the use of the stirring device 1 according to the present embodiment. Good. Then, for example, it is preferable to enable control such that the motor is driven for 5 minutes every 60 minutes. INDUSTRIAL APPLICABILITY As described above, according to the present invention, a stirrer charging container having a bottom 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, and a vibration generator is provided below the center of the bottom of the container. The vibration of the vibration generator itself, including the weight of the vibration generator itself, is efficiently transmitted to the container, and the vibration causes the object to be stirred (contents) in the container. Not only is the material rotated by a continuous number of semicircular arcs, but also the rotation direction is changed only by operating the vibration generator. .

The invention according to claim 2 is characterized in that a stirrer charging container having at least a bottom formed in a single arc shape is held on a support base via an elastic material, and vibration is generated so that vibration can be applied to the container. It is characterized by the fact that the agitator is installed, so that even if the bottom is a single arc, the vibration generator can vibrate to apply a propulsive force in a certain direction to the agitated object (contents) in the vessel, As a result, an excellent effect of rotating the contents can be obtained. Industrial applicability

As described above, the stirring apparatus according to the present invention uses a knife such as a knife in food garbage to stir only by the vibration generated by the vibration generator 6, that is, without using the rotary blade pieces. There is no problem of generating a loud noise even when foreign objects such as spoons are contained, and there is no problem of damaging the container with the foreign objects, and the whole can be agitated uniformly. Therefore, if the bacteria bed is put in the container 2 to be stirred and garbage (not shown) is put on the bed, the garbage rotates with the bacteria bed reliably and efficiently without unevenness. It is agitated, and with sufficient contact with the microorganisms contained in the microbial bed, it is degraded over time and disappears.

In the above embodiment, the case where the stirrer 1 is applied to a stirrer for garbage disposal has been described as an example. However, it is needless to say that the stirrer 1 can also be used as a sand remover for bivalves such as clams or a rice washing machine. .
