DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for biodegrading garbage with microorganisms and liquefying the garbage.

[0002]

2. Description of the Related Art Conventionally, a composting-type garbage disposal apparatus that obtains compost by fermenting garbage such as vegetable scraps, fish bones, and garbage in a treatment tank containing a bed of sawdust and the like is used. It has been widely used. However, since this composting apparatus uses a high-temperature fermenter having a fermentation temperature of about 60 to 80 ° C., a large-capacity heating means is required. Further, there is a problem that a peculiar unpleasant odor is generated during fermentation. Also, if a large amount of water is added to the sawdust, it becomes clay-like and hinders fermentation. In addition, the compost produced had to be removed and bagged.

[0003] In recent years, liquefaction type devices have been developed in order to solve the drawbacks of the compost type devices. FIGS. 6 and 7 show a liquefaction-type garbage disposal apparatus. In the garbage processing apparatus 71 shown in each figure, a stationary processing tank 75 having a garbage input port 81 on the upper surface is installed on a base 83 in a main body casing 72. The bottom surface of the processing tank 75 is formed of a liquid-permeable member 9 formed by forming a punching metal having a large number of pores into a curved surface.
2 is comprised. A rotating shaft 95 around a horizontal axis is rotatably provided in the processing tank 75 via bearings 76 and 77. A stirring blade 96 for stirring the garbage and the bacteria bed is attached to the rotating shaft 95 via a connecting leg 97. Below the processing tank 75, a liquid storage tank 82 for storing liquefied matter generated by decomposition is provided.

According to the garbage disposal apparatus 71, the lid 8
0 is opened, and a germ bed such as chaff and garbage are introduced into the treatment tank 75 from the garbage inlet 81. The garbage brought in is
Due to the action of aerobic fermenters that inhabit the bacterial bed, they are slowly decomposed mainly into carbon dioxide and liquefied substances (main component is water). During the disassembly process, the geared motor 78 is started periodically, and its rotational force is transmitted to the rotating shaft 95 to further rotate the stirring blade 96. Thereby, the bacteria bed and the garbage in the processing tank 75 are stirred, and the decomposition of the garbage is promoted.

The liquefied matter generated by the decomposition of the garbage passes through the liquid permeable member 92 and is stored in the liquid storage tank 82. At this time, the air sent from the aeration blower 85 blows out from the aeration pipe 84 to aerate the liquefied material, thereby further promoting the decomposition of the liquefied material. The liquefied material after the aeration is discharged out of the apparatus from the drain pipe 86. When supplying water to the bacteria bed and the garbage, the electromagnetic on-off valve 91 is opened and the water supply pipe 90 is closed.
From the sprinkling pipe 89 is sprayed into the processing tank 75.
In a low temperature such as winter, the heater 94 is energized,
The inside of the processing tank 75 is maintained at a temperature suitable for biodegradation.

[0006] The above-mentioned garbage disposal apparatus 71 uses a low-temperature fermentation bacterium that ferments garbage at room temperature and liquefies it, so that a heater or the like is not usually required. Since these fermenting bacteria are relatively resistant to water, it is not necessary to drain the garbage when putting them in. Also, due to the nature of these fermenters,
Almost no peculiar unpleasant odor during fermentation. Since the obtained liquefied material is easy to handle and contains many fertilizing ingredients,
It has the advantage that it can be used immediately as liquid fertilizer.

[0007]

By the way, garbage often contains a vinyl bag or a nylon string. When such garbage is put into the garbage disposal device 71, the liquid-permeable member 92 is clogged by a vinyl bag or the like, and prevents the liquefied material from flowing down. Similarly, a hard foreign material such as a fork may be mixed in the garbage. If these foreign substances are caught between the stirring blade 96 and the liquid permeable member 92, they may cause a mechanical failure or in the worst case, the liquid permeable member 9
2 may be damaged. When the liquid-permeable member 92 is damaged in this manner, the bacteria bed must be taken out first, and then the stirring blade 96 must be removed and then repaired, which makes repair work difficult and takes a great deal of labor and time.

On the other hand, even when the liquid permeable member 92 is clogged, there is no means for removing the clogging of the liquid permeable member 92, and it is difficult to check the clogging itself. In addition, the stirring blade 96 must be driven in a bacterial bed or garbage having a large flow resistance, and a large driving power is required. When rice hulls are used as the fungal bed, the resistance of the rice husks to bite into the liquid-permeable member 92 increases, so that even greater power is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has a simple structure which enables efficient stirring of bacterial beds and garbage with relatively small power requirements. An object of the present invention is to provide a garbage disposal apparatus that can eliminate clogging of members.

[0010]

To achieve the above object, a garbage disposal apparatus according to the present invention comprises:
A processing tank including a processing tank drum rotatably supported by the main body frame and containing a bacterial bed and garbage; and a power source connected to a pivot shaft of the processing tank drum to rotationally drive the processing tank drum. At least a part of the drum peripheral surface is formed of a liquid permeable member, and a liquid storage tank for receiving the liquefied material flowing out of the liquid permeable member is disposed below the processing tank drum.

In the above construction, the processing tank drum is disposed on the main body frame at an axis inclined obliquely to the horizontal direction, and a garbage inlet is formed at the upper end of the cylinder of the processing tank drum. It is.

Further, in the above construction, the processing tank drum is disposed around the substantially horizontal axis on the main body frame, and a garbage inlet which can be opened and closed by a lid is formed on the peripheral surface of the processing tank drum. Things.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing the inside of a garbage processing apparatus according to an embodiment of the present invention, and FIG. 2 is a plan view showing a part of the inside of the garbage processing apparatus. In the garbage processing apparatus 1 shown in each figure, a base 13 is disposed at the bottom of a trapezoidal box-shaped main casing 2, and a main frame 4 is erected at a front portion on the base 13. A main body frame 3 shaped like a letter as viewed from the side is provided upright at a rear portion on the base portion 13.

A processing tank drum 5 for accommodating a bacterial bed 28, garbage 29, and the like is rotatably supported between the body frames 3 and 4. The processing tank drum 5 is formed in a substantially frustoconical cylindrical body. A pivot shaft 5 a on the rear end side of the processing tank drum 5 is pivotally supported by the main body frame 3 via a bearing 6. The front end side of the processing tank drum 5 is pivotally supported by the main body frame 4 via a pair of left and right wheel bearings 7 that roll on the peripheral surface of a cylindrical bearing tube 17. That is, the processing tank drum 5 is disposed so that its axis A is obliquely inclined with respect to the horizontal direction, and the cylindrical opening near the bearing cylinder 17 is formed as the garbage input port 11. The processing tank drum 5
A geared motor 8 (an example of a power source) that rotationally drives is connected to a pivot shaft 5a of the processing tank drum 5 via a chain 8a or the like. Here, the geared motor 8 has, for example, a motor efficiency of about 90% and a capacity of about 0.2 kWH.

Four rectangular openings are formed on the peripheral surface of the processing tank drum 5, and liquid-permeable members 22 are screwed through synthetic resin frames so as to cover these rectangular openings. The liquid-permeable member 22 is made of, for example, a stainless steel plate having a thickness of 1 mm, and is made of a punching metal provided with a large number of perforations having a diameter of 1 mm. In addition, these perforations are 1 mm as described above.
The diameter is not limited, and the liquefied material 25 after decomposition without passing through the bacteria bed 28 and the garbage 29 may be appropriately set to have a pore size that can pass through. Below the processing tank drum 5, a saucer-type storage tank 12 that receives the liquefied material 25 dropped through the liquid-permeable member 22 is disposed. A drain pipe 16 communicating with the outside is connected to a side surface of the liquid storage tank 12, and an aeration pipe 14 for blowing air to the liquefied material 25 is provided at a bottom of the liquid storage tank 12. The aeration tube 14 is connected to the aeration blower 15 that sends out air by piping.

The opening formed in the main body casing 2 at the outside of the garbage input port 11 is provided with the garbage input port 11.
A guide cylinder 9 slidable on the inner surface is mounted. The guide cylinder 9 is provided to guide the bacteria bed 28 and the garbage 29 as far as possible in the treatment tank drum 5. The garbage input port 11 is sealed with the outer lid 10 except at the time of input.
In addition, a water spray pipe 1 for spraying water toward the liquid-permeable member 22 is provided above the processing tank drum 5 at a position facing the liquid-permeable member 22.
9 are deployed. The water sprinkling pipe 19 communicates with a water supply pipe 20 via an electromagnetic on-off valve 21. In addition, an inspection opening for maintaining and inspecting the liquid permeable member 22 is formed on the upper surface of the main casing 2, and is sealed with an inspection lid 23 except when the inspection is performed.

Further, a heater 24 for maintaining the inside of the processing tank drum 5 at a predetermined temperature is provided in the main body casing 2. As the heater 24, for example, a heating blower for heating and sending out air is used. However, the heater 24
For example, an electric heater, a steam heater, or the like may be used. The bacteria bed 28 used in the garbage disposal apparatus 1 is preferably a bed which is easy to inhabit aerobic fermentation bacteria which decompose garbage 29 at a relatively low temperature. Such a bacterial bed 28
Examples thereof include rice hulls, wood chips, and sawdust, and here, rice hulls were used. Further, the reference amount of the garbage 29 is approximately 1 part by volume with respect to the 15-volume bacterial bed 28, and the apparatus can process 30 kg of garbage 29 per 24 hours.

Here, the control configuration of the garbage processing apparatus 1 is shown in FIG. In the garbage processing apparatus 1, the control of the main operation is controlled by a control device 18 composed of, for example, a microcomputer chip. A thermometer 26 for detecting a temperature near the processing tank drum 5 in the main body casing 2 is connected to an input side of the control device 18 by a signal. The heater 24, the geared motor 8, the electromagnetic on-off valve 21, and the aeration blower 15 are connected to the output side of the control device 18 by signals.

Subsequently, the garbage disposal apparatus 1 having the above-described configuration will be described.
The processing operation of the garbage 29 will be described. First, outer lid 1
0 is opened, and a predetermined amount of the bacterial bed 28 is charged through the garbage input port 11. Then, when an operation switch (not shown) is turned on, the control device 18 operates the heater 24 so that the temperature inside the device detected by the thermometer 26 approaches a preset target temperature. However, since the fermentation heat of the aerobic fermentation bacterium keeps the inside of the treatment tank drum 5 at an appropriate temperature from spring to autumn, the heater 24 is not required to be used except during severe winter.

On the other hand, the control device 18 activates the geared motor 8 to periodically rotate the processing tank drum 5 at a speed of 1 to 2 rpm. The rotation operation of the processing tank drum 5 is performed by a timer once every hour for about 5 minutes. While the inside of the apparatus is maintained at the target temperature, garbage 29 and an appropriate amount of p
The H adjuster is introduced through the garbage inlet 11. At this time,
The upper surface 27 of the stored bacteria bed 28 and the garbage 29 is set to a height when the amount of the bacteria bed 28 and the garbage 29 is about 1/2 of the inner capacity of the processing tank drum 5. But
This is preferable in that the stirring efficiency and the processing efficiency can be increased. Also,
What is necessary is just to throw in the pH adjuster in the quantity which can make the whole container which is easily acidified by decomposition | disassembly approach the neutrality.

Thus, the bacteria bed 28 and the garbage 29 are agitated by the periodic rotation of the processing tank drum 5. As a result, a sufficient amount of air is sent into the bacterial bed 28, and the bacterial bed 28 and the garbage 29 are evenly mixed, so that the decomposition of the garbage 29 is promoted. In other words, in this apparatus, a stirring means for stirring the bacteria bed 28 and the garbage 29 by the processing tank drum 5 provided rotatably about the oblique axis and the geared motor 8 for driving the processing tank drum 5 to rotate. Is configured. Incidentally, there are countless thorns on the surface of the rice hulls, which act as a file to finely crush the garbage 29 and assist in the decomposition.

As a result, the garbage 29 is decomposed into carbon dioxide, water, etc. by a plurality of types of aerobic fermentation bacteria, and is liquefied almost day and night without any trace. Since the liquefied material 25 thus obtained also contains aerobic fermentation bacteria, even if the organic matter in the course of decomposition leaks out of the perforations of the liquid permeable member 22 and falls into the liquid storage tank 12, the aeration tube 14 It is decomposed and purified by aeration. The liquefied material 25 is B
Since it contains an OD component, a COD component, and an SS component, it is preferable to transfer it to a downstream septic tank or water treatment facility for water treatment. On the other hand, if the liquefied material 25 is appropriately diluted with water, it can be used as liquid fertilizer.

Therefore, according to the garbage disposal apparatus 1 having the above structure, the bacteria bed 28 and the garbage 29 are lifted up and fall down in the rotating treatment tank drum 5, whereby
The bacteria bed 28 and the garbage 29 are uniformly and smoothly stirred. In addition, since the garbage processing apparatus 1 does not have a stirring blade unlike the conventional apparatus, even if foreign matter is introduced, the foreign matter does not bite. Therefore, the geared motor 8 has a simple configuration and requires a small power.

The fermentation bacteria for liquefaction of garbage are resistant to water and, in addition, use rice husks for the bacterial bed. Therefore, even if water is sprayed in the treatment tank drum 5, there is no problem. Has a humidifying action in the treatment tank drum 5 and a washing action on the rice husk surface. Therefore, when the liquid permeable member 22 reaches the upper part of the processing tank drum 5, most of the contents fall to the lower part in the processing tank drum 5 by its own weight. In addition, since the control device 18 opens the electromagnetic on-off valve 21 and sprays water from the water sprinkling pipe 19 to forcibly clean the liquid permeable member 22, the liquid permeable member 22 is further improved.
Clogging can be prevented.

If the liquid-permeable member 22 is still clogged, the liquid-permeable member 22 can be easily removed simply by loosening the screws and removing the synthetic resin frame. Can be washed. Then, the inside of the drum can be inspected through the removed rectangular opening of the liquid-permeable member 22 and the removed inspection opening of the inspection lid 23. If foreign matter is accumulated in the drum, the foreign matter is passed through the rectangular opening and the inspection opening. It is also possible to remove.

If an inspection hatch (not shown) is provided on the side wall of the main body casing 2 above the liquid storage tank 12, the inside of the main body casing 2 and the liquid storage tank 12 can be inspected. The inside of the tank 12 can be periodically cleaned. Further, since the upper end opening of the processing tank drum 5 is used as the garbage input port 11, even if the processing tank drum 5 rotates, the bacteria bed 28 and the garbage 29 in the drum do not reach the garbage input port 11. Therefore, the structure of the outer lid 10 that seals the garbage input port 11 is simple, and the garbage 29 can be easily input.

The present invention may employ a processing tank drum which rotates about a horizontal axis. Such a garbage disposal apparatus is shown in FIG. 4 and FIG. In the garbage processing apparatus 1a shown in each figure, reference numeral 33 denotes a rear body frame, 34 denotes a front body frame, 35a denotes a pivot shaft of the processing tank drum 35, and 36 and 37 denote front and rear pivot shafts 35a, 35a. 35

It corresponds to the main body frame 3, the main body frame 4, the processing tank drum 5, the pivot shaft 5a, the geared motor 8, and the outer lid 10 of the garbage processing apparatus 1 of the above-described embodiment, and has the same function as each. ing.

Subsequently, reference numeral 42 denotes a liquid storage tank, 43 denotes a base,
44 is an aeration tube, 45 is an aeration blower, 48 is a control device,
9 is a water pipe, 50 is a water supply pipe, 51 is an electromagnetic on-off valve, 53 is an inspection lid, 54 is a heater, and 60 is a chain. These components are also used for the liquid storage tank 12, the base 13, the aeration pipe 14, the aeration blower 15, and the garbage disposal apparatus 1 of the embodiment described above.
Control device 18, watering pipe 19, water supply pipe 20, electromagnetic on-off valve 2
1, corresponding to the inspection lid 23, the heater 24, and the chain 8a, and have the same function as each.

In this garbage processing apparatus 1a, the processing tank drum 35 is formed in a cylindrical shape, and is disposed around a horizontal axis B. The vicinity of both sides of the outer peripheral surface of the processing tank drum 35 is formed of four liquid-permeable members 52 in the circumferential direction. A liquid storage tank 42 that receives the liquefied material that has passed through the liquid permeable member 52 is disposed below the processing tank drum 35. Further, a garbage input port 57 is formed on the peripheral surface of the central portion of the processing tank drum 35. The garbage inlet 57 is configured to be opened and closed by a lid 55. Lid 55
Are slidably mounted on a lid guide 56 arranged along both side edges of the garbage inlet 57 in the circumferential direction of the drum.

Accordingly, the garbage disposal apparatus 1 having the above-described configuration is used.
In the case of a, it is needless to say that a driving source having a small required power is sufficient, and since the internal space of the processing tank drum 35 can be widely used up to the upper surface position indicated by the reference numeral 27, a large amount of garbage 29 (for example, (About 200 to 5000 kg).

In each of the above embodiments, a punching metal is used as the liquid-permeable member, but the invention is not limited to this. For example, a metal net made of a wire that is hardly rusted, a knitted body made of a high-strength synthetic resin fiber, and the like can also be used as the liquid-permeable member. Further, the liquid permeable member is not limited to the mode used for a part of the outer peripheral surface of the processing tank drum, and it is also possible to configure almost the entire outer peripheral surface of the processing tank drum with the liquid permeable member.

If, for example, an infrared lamp is provided in the main casing near the processing tank drum, the temperature in the processing tank drum can be controlled and the growth of photosynthetic bacteria can be promoted.

[0033]

As described above, according to the garbage disposal apparatus according to the present invention, the bacteria bed and the garbage roll in the rotating treatment tank drum, so that the bacteria bed and the garbage can be smoothly stirred. Can be. Further, since there is no agitating blade as in the conventional apparatus, even if foreign matter or the like is introduced, the foreign matter does not bite. Because of these advantages, the present invention is simple to configure and requires a low power drive source. in addition,
When the liquid permeable member comes to the upper part of the rotating processing tank drum, most of the bacteria bed and garbage or foreign substances attached to the liquid permeable member fall to the lower part of the processing tank drum by its own weight. Significant clogging of the liquid permeable member can be avoided.

When the processing tank drum is disposed at an axis inclined obliquely to the horizontal direction and a garbage inlet is formed at the upper end of the cylinder of the processing tank drum, the bacteria bed and the garbage are efficiently stirred. be able to. In addition, since the cylindrical opening at the upper end of the processing tank drum can be used as the garbage input port, the structure of the lid for sealing the garbage input port can be simplified, or the apparatus can be hindered without providing this lid. It is possible to drive without waste, and it becomes easy to put in garbage.

When the processing tank drum is arranged around a substantially horizontal axis, and a garbage inlet that can be opened and closed by a lid is formed on the peripheral surface of the processing tank drum, the internal space of the processing tank drum can be widely used. Therefore, the bacterial bed and the garbage can be accommodated and processed in a relatively large amount.
