Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for treating garbage discharged from homes or restaurants using fermentation bacteria. Specifically, the chips (small pieces of wood), which serve as a bacterial bed on which the fermenting bacteria grow and proliferate, can be mixed with the garbage by a smaller driving force. It is an object of the present invention to provide a garbage disposal apparatus capable of preventing remaining garbage from remaining.

[0002]

2. Description of the Related Art Conventionally, a chip containing fermentative bacteria and garbage are mixed by stirring, focusing on the decomposing action of organic matter by fermenting bacteria, and the garbage is fermented by the decomposing action of the fermenting bacteria in contact with the garbage. A garbage disposal apparatus that can be extinguished has been proposed.

FIG. 5 is a partially cutaway perspective view showing a configuration of a conventional garbage processing apparatus using such a fermentation bacterium.

In FIG. 5, reference numeral 61 denotes a container for holding chips and garbage containing the fermenting bacteria (hereinafter, both are collectively referred to as "agitated object"), and the agitated object is stirred therein. Will be This container 61 has an upper opening formed in a square shape, and a lower portion formed in a semicircular cross section, and a pair of cross sections L on a square plate base 71.
It is held upright by holding members 72a and 72b in the shape of a letter.

[0005] A rotary shaft 52 that is rotated by the drive of a motor (not shown) is provided through the container 61 at an axial center of the semicircular section of the container 61. The hollow shaft 51 is fitted to the rotary shaft 52 located in the container 61, and the hollow shaft 51 is fixed to the rotary shaft 52 by screws. Therefore, when the rotating shaft 52 rotates, the hollow shaft 51 also rotates.

[0006] On the hollow shaft 51, four rotating blades 41a to 41d having a rectangular cross section for agitating an object to be agitated are fixed at equal intervals. The length of the rotary blades 41 a to 41 d is slightly shorter than the inner diameter of the semicircular portion of the container 61. The reason why the cross section is formed in a V shape is to rotate the object to be stirred inside the container 61. The rotary blades 41a to 41d are provided with three blanking portions 42, as shown in FIG. The punching empty portions 42 are provided to prevent garbage from adhering to the rotating blades 41a to 41d. In FIG. 6A, only one rotating blade 41a is shown for simplicity of description, but the other three rotating blades 41b to 41d have the same configuration.

[0007] These rotating blades 41a-d are shown in FIG.
As shown in (b), the third rotating blade 41b is rotated counterclockwise about the axis of the rotating shaft 52 by 45 degrees with respect to the first rotating blade 41a. 4
1c is rotated by 90 degrees in the same direction about the axis with respect to the second rotary blade 41b.
1d are respectively fixed to the hollow shafts 52 so as to be at positions rotated by 45 degrees in the same direction with respect to the third rotating blades 41c around the axis with respect to the third rotating blades 41c. That is, the rotating blades 41a to 41d are fixed to the hollow shaft 52 in a spiral shape.

Next, a description will be given of a method of using the apparatus configured as described above. In FIG. 5, a chip containing a fermentation bacterium is put in a container 61 in advance before starting the apparatus. The input amount is approximately 70% of the volume of the container 61
The degree is preferred.

Then, when the apparatus is operated, the rotating blades 41a to 41d rotate, and accordingly, the chips rotate inside the container 61. The rotation speed is adjusted by appropriately setting the rotation speed of the motor by a controller (not shown).

Therefore, garbage is thrown into the rotating chips. At this time, the inside of the container 61 is at a temperature condition (40 degrees Celsius or higher) at which the fermentation bacterium is easily activated by the fermentation action of the fermentation bacterium without using a heating means. It is desirable that the ratio of chips to garbage is about 10: 1 in volume ratio. In that case, each rotating blade 41a-d
Some of the rotating blades 41a to 41d are not entirely buried in the object to be stirred, but are partially exposed from the object to be stirred.

When the garbage is put into the rotating chips, the chips and the garbage are agitated and mixed in the container 61 by the rotation of the rotary blades 41a to 41d. The garbage introduced by the fermentation action of the fermentation disappears.

[0012]

However, according to the above conventional example, there are the following problems to be solved. That is, the rotating blades 41a to 41d exposed from the stirring target
When the part infiltrates into the object to be stirred as it rotates, a large torque is required because it intrudes into the object to be stirred by pressing it. This is particularly noticeable whether the apparatus is being started or is operating, or if the object to be stirred is wet.

Further, since the four rotating blades 41a to 41d are provided in a spiral shape, each of the rotating blades 41a to 41d is formed.
Due to the rotation of d, the object to be stirred is pressed in the axial direction of the rotating shaft 52, and the object to be stirred is pressed against one end of the container 61. Therefore, each of the rotating blades 41a to 41d always infiltrates the object to be stirred, which is pressed and has increased resistance to press-fitting. This also
This causes a large torque requirement.

As a result, when a motor with a small supplied motor torque is used, the rotating blades 41a are operated during operation of the apparatus.
~ D may stop rotating, in which case,
The starting torque was manually applied to the rotating blades 41a to 41d. On the other hand, if a motor having a larger output torque is used to cope with this, the manufacturing cost and running cost of the device will increase.

As described above, in the conventional example shown in FIG. 5, as a first problem, it is required to rotate the rotary blades 41a to 41d in a state in which the object to be stirred is contained in the container 61. There were problems to be solved regarding torque.

Further, according to the conventional example shown in FIG. 5, the proportion of the garbage put into the container 61 decomposed by the operation of the apparatus is 90 to 95%, and the remaining 5 to 10% is There is a problem to be solved that a residue that cannot be processed remains in the container 61.

What remains as this residue is cellulose, minerals, starch, seasonings or food additives contained in the garbage, which do not disappear due to the decomposing action of the fermenting bacteria, That is, they remain in the container 61 in a state. If the amount of the residue remaining inside the container 61 increases sequentially due to repeated use of the device, the amount of garbage that can be accommodated in the container 61 decreases accordingly, and the device Workability is reduced.

On the other hand, if the amount of the residue accumulated inside the container 61 increases, the void formed by the point contact between the chips is clogged by the residue.
In particular, since cellulose is viscous, it sticks to the chip and closes the void. If the gaps between the chips are clogged, the flow of air from the outside will be impaired, and the activity of fermenters that require oxygen will become inactive, and efficient fermentation and elimination of garbage will be realized. Can not do.

Therefore, in the conventional example shown in FIG. 5, the residue is discharged from the container 61 and discarded together with the chips stored in the container 61 every two to three months, for example. In that case, even though the chip is still usable, the chip was discarded together with the residue, so that when the device was used, a new chip had to be stored in the container 61, which increased the running cost of the device. Was invited.

The chips that rotate together with the garbage in the container 61 are worn and crushed due to the repeated use of the apparatus. If the chip is abraded and crushed to be miniaturized, the function as a microbial bed will be reduced or eliminated. In such a case, a method of periodically taking out chips from the container 61, sieving the chips, and then refilling the still usable chips into the container 61 and replenishing the shortage is a burden on the maintenance of the apparatus. Enlarge. On the other hand, the method of discarding all the chips taken out of the container 61 and replacing them with new chips increases running costs.

As described above, the conventional example shown in FIG.
As a second problem, there is an unsolved problem that no countermeasures have been taken against chips that have been reduced in size due to residues of garbage and wear and crush.

In addition, if garbage contains a knife or a fork discarded by mistake, the knife or the like is caught in the rotating blades 41a to 41d during operation of the apparatus, and the container 61 The conventional example shown in FIG. 5 also has a problem to be solved in that a knife or the like is sandwiched between the inner wall of the rotary blades and the tips of the rotary blades 41a to 41d, thereby stopping the rotation of the rotary blades 41a to 41d. .

[0023]

The present invention has been made in order to solve the above-mentioned problems. For this purpose, the present invention takes the following measures. That is, the lower part of the container that stores the object to be stirred is formed in a semicircular cross section. A rotating shaft is provided at a lower axis portion of the container having a semicircular cross section so as to penetrate the container. At least two rotating plates that are rotated by rotation of a rotating shaft are disposed inside the container. An outlet is provided on one side wall of the container parallel to the rotation axis for discharging garbage residue and small chips. The above means are used in the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG.
And will be described. Here, FIG. 1 is a partially cutaway perspective view showing the present embodiment, and the same components as those in FIG. 5 are denoted by the same reference numerals.

Referring to FIG. 1, a description will be given of a difference of the garbage processing apparatus according to the present embodiment from the configuration of the conventional example shown in FIG. First, in the present apparatus, four flat rotating plates 11a to 11d are used as means for stirring and mixing the object to be stirred.
Is used. Experiments conducted by the inventor of the present application have confirmed that the agitated object rotates in the container 21 even when such flat rotating plates 11a to 11d are used. Rotating plate 1
The radii 1a to 1d are the same as the lengths of the rotating blades 41a to 41d in the conventional example shown in FIG.

These rotating plates 11a to 11d are shown in FIG.
As shown in (front view), six U-shaped cutouts 12 are provided at equal intervals on the outer peripheral side and formed in a gear shape. These notches 12 are not necessarily essential components of the present invention, but if these notches 12 are provided, the object to be stirred moves in the axial direction of the rotary shaft 52 through the notches 12. And smoother stirring and mixing can be realized. In addition, an effect of crushing garbage can be obtained. Therefore, this notch 12 ...
Is not limited to a U-shape.
The shape may be a U-shape or a U-shape.

Further, a portion on the center side of the notch portion 12... For preventing garbage from adhering to the rotating plate 11a,
Six circular holes 13 are formed at regular intervals in a circular shape. In FIG. 2A, only one rotary plate 11a is shown for simplicity of description, but the other three rotary plates 11b to 11d have the same configuration.

The rotary plates 11a to 11a formed as described above
d is a hollow shaft 51 as shown in FIG. 2B (side view).
From one end to the other end, the hollow shafts 51 are fixed at equal intervals so as to pass through the centers of the rotating plates 11a to 11d. One thin cylindrical auxiliary rod 14 is arranged between the peripheral edges of the rotary plates 11a to 11d so as to be mutually rotated by 120 degrees about the axis of the rotary shaft 52. Has been established. These auxiliary rods 14 ...
Is for rotating and raising heavy garbage, for example, when the garbage contains heavy garbage, and is not an essential component of the present invention.

In FIG. 1, the present apparatus is further different from the configuration of the conventional example shown in FIG. 5 in that a substantially central portion of one side wall 22a of the container 61 parallel to the rotation axis 52 is provided.
A plurality of discharge ports 23, which are circular holes, are formed in a matrix in order to discharge the residue left behind by the garbage and the chips that have been reduced due to wear and crushing. The diameter of the outlets 23 is preferably about 4 mm. The outlets 23 also have the effect of taking in air from the outside into the inside of the container 21 to activate the activities of fermenters that require oxygen. Except that the outlets 23 are provided, the configuration of the container 21 itself is the same as the container 61 in the conventional example shown in FIG.

Further, since the discharge port 23 for discharging the garbage residue and the miniaturized chips is provided, the discharge container 31 for storing the discharge such as the residue is closely attached to the side wall 22a of the container 61. This is also different from the configuration of the conventional example shown in FIG.

The waste container 31 is shown in FIG. 3 (perspective view).
And the arc-shaped ends 33 of the side walls 32 are formed on the side wall 22a of the container 61 (FIG. 1).
It is arranged without being fixed on the base 71 so as to be in close contact with the base 71. The components other than the components described above are the same as the components in the conventional example shown in FIG.

Next, the situation when the garbage processing apparatus having such a configuration is operated will be described. In FIG. 1, each of the rotating plates 11a to 11d rotated by driving a motor
The object to be stirred contained in the container 21 is stirred and mixed by the rotation of. At this time, unlike each of the rotating blades 41a to 41d in the conventional example shown in FIG.
Since the occupied space which is already infiltrated into the object to be stirred is rotated, unlike the rotating blades 41a to 41d in the conventional example shown in FIG. Not at all. Therefore, a large torque as in the conventional example is not required.

In addition, the object to be stirred is partitioned by the rotating plates 11a to 11d in the container 21 and divided into three parts, each of which is rolled and rotated. In other words, since the rotating blades 41a to 41d are provided in a spiral shape as in the conventional example shown in FIG. 5, no pressing force is generated in the axial direction of the rotating shaft 52. Does not increase. In this respect, a large torque is not required as in the conventional example. According to the present invention, about 5% of the torque required in the prior art is required.
0% is sufficient. In addition, since the thing to be stirred rotates like a roll, the garbage and the chip rotate integrally, and the effect that decomposition of the garbage is promoted is also obtained.

FIG. 4A shows a state of rotation of the object S when the rotary blades 11a to 11d are rotated clockwise in the drawing. In this case, the object S to be stirred is placed in the container 2
1, the portion where the agitated object S rotates upward rotates along one side wall 22 b of the container 21. On the other hand, the portion on the rotation lowering side of the stirring target S does not descend along the other side wall 22a, but when the stirring target S rises above the rotation shaft 52, the lower portion is lowered from there. It descends as it collapses. As a result, a gap is formed between the side wall 22a and the object S to be stirred, as shown in the figure.

FIG. 4B shows a case where the rotating shaft 52 is rotated counterclockwise. In this case, the material to be stirred is moved along the side wall 22a on the side where the waste container 31 is arranged. S rises, and a gap is formed between the rotating lower side wall 22b and the object S to be stirred. The above experimental results have been obtained by the experiments of the present inventor.

Therefore, if the amount of garbage put into the container 21 is, for example, 1.5 kg, the object S is rotated clockwise for 11 hours and 30 minutes as shown in FIG. Stir and mix.

Thereafter, as shown in FIG. 4B, the object S is rotated counterclockwise for 30 minutes. In that case,
The object S is rotated upward along the side wall 22a on the side where the waste container 31 is disposed, and the side walls 22a have discharge ports 23 for discharging garbage and small chips. Are drilled. Therefore, the garbage residue and the miniaturized chips contained in the object to be stirred S rotating and ascending along the side wall 22a are transferred to the container 2 through the discharge ports 23.
1 and is stored in the discharge container 31. By the operation of the apparatus for the above 12 hours, the garbage put in the container 21 disappears by fermentation.

The residue D accumulated in the waste container 31
Is in the form of dry fine powder and can be incinerated. In addition, since the residue D contains bacteria and does not contain pathogenic bacteria, it can be used as a suitable fertilizer.

When the chips in the container 21 are reduced due to the discharge of the miniaturized chips from the container 21, only the reduced amount of chips needs to be refilled in the container 21. The chips remaining in the container 21 without abrasion crushing progressing so much can be used as a bed of fermentation bacteria as they are.

Therefore, according to the present apparatus, the chips in the container 21 are periodically taken out and sieved, and then the chips still usable can be re-entered in the container 21 and the shortage can be replenished. It is not necessary to replace all chips, including those still usable, with new chips. It is only necessary to consider the loss due to wear and crushing of the chip. This is extremely advantageous in terms of maintenance and running costs of the device.

In the above, the case where the lower part of the container 21 is formed in a semicircular cross section and one rotating shaft 52 is disposed to rotate the rotating plates 11a to 11d has been described.
However, the present invention is not limited to this. After forming the lower part of the container 21 so that two semicircles are arranged in parallel in the diameter direction to form a three-character cross section, the lower part of the container 21 A rotating shaft may be provided to rotate the two sets of rotating plates 11a to 11d. In this case, a discharge port 23 for discharging garbage and the like is formed in both side walls 22a and 22b of the container 21 parallel to the rotation axis, and the two sets of rotation plates 11a to 11d are opposite to each other. To rotate in the direction.

As means for stirring the object S to be stirred, 4
The case where the three rotating plates 11a to 11d are used has been described.
However, the present invention is not limited to this, and the present invention is applicable when using at least two rotating plates spaced at a predetermined interval.

Furthermore, a case has been described where a circular hole outlet 23 is formed in one side wall 22a of the container 21 in order to discharge garbage residues and chips that have been reduced in size. A plurality of narrow slits extending in the direction may be provided.

[0044]

As is apparent from the above description, according to the present invention, a flat rotating plate is used as a means for stirring the object to be stirred contained in the container. There is no need to press it into the agitated material. Therefore, since a motor having a small output torque can be used, the manufacturing cost and running cost of the device can be reduced.

Moreover, even if a knife or a fork is mixed in the garbage, the knife or the like does not get caught in the rotating blade and stops the rotation of the rotating blade as in the conventional example. Operational stability is ensured, and the reliability of the device is improved.

Further, since the garbage residue is discharged to the outside of the container by the operation of the apparatus, even if the apparatus is used repeatedly, the amount of garbage that can be accommodated in the container is reduced due to accumulated residue and the like. Therefore, the workability of the apparatus is not reduced.

Further, the gap formed by the point contact of the chips in the container does not cause clogging due to the residue. If clogging does not occur, a good flow of air from the outside will be ensured, and as a result, the activities of fermentative bacteria that require oxygen will become active, and it will be possible to realize efficient fermentation disappearance of garbage .

Further, since the residue does not accumulate in the container, as in the conventional example, the residue is periodically discarded.
It is not necessary to discharge the residue from the container together with the chips housed in the container and dispose of the chips still usable. That is, the chip in the container can be effectively used as long as it can withstand use, and it is possible to avoid an increase in the running cost of the device.

In addition, chips that have been abraded and crushed by overlapping use of the apparatus and do not function as a fungus bed are also discharged outside by the operation of the apparatus. as a result,
After regularly removing chips from the container and sieving them, re-use the chips that are still usable in the container,
Alternatively, there is no need to discard all chips taken out and replace them with new chips. It is only necessary to refill the shortage in the container, considering only the loss of chips,
This is advantageous in terms of maintenance and running cost of the apparatus. Therefore, the effect of the present invention is extremely large.
