DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fermentation treatment apparatus for composting garbage by utilizing microbial decomposition of garbage and a garbage pulverization and fermentation treatment apparatus using the same.

[0002]

2. Description of the Related Art Conventionally, many garbage pulverizing and fermenting treatment apparatuses for composting by utilizing microbial decomposition are disclosed in JP-A-5-221766 and JP-A-4-4084. Are known. In these technologies, when removing the composted fermentation contents from the treatment tank of the fermentation treatment device, remove the bottom plate of the treatment tank,
It is housed in a plastic bag or the like.

In such a technique, when the contents of the fermentation treatment are taken out, there is a case where the inside of the fermentation treatment is taken out from the outlet at the bottom of the treatment tank. I can't take it out.
In this case, the contents of the fermentation treatment cannot be sufficiently removed. In addition, the operability of a plastic bag is poor unless there is a dedicated device for fixing the storage bag in a large size. Furthermore, in the case where the fermentation treatment contents are contained in a plastic bag, the contents of the fermentation treatment can be easily touched with hands, so that gloves and the like are required for hygiene.

[0004]

Here, as means for solving these problems, a slide type take-out plate is provided at the bottom of the treatment tank, and the fermentation treatment contents which fall by removing this take-out plate are placed underneath. It is conceivable to collect them in a take-out box installed at

However, according to this technique, it is difficult to install a large-capacity take-out box because the space under the treatment tank is limited, so that the fermentation contents that can be taken out at a time are limited. It is assumed to be only about 8L. Then, in order to take out 20 to 30 L of the fermentation processing contents, the same operation needs to be repeated three or four times.

In this technique, it is conceivable to raise the processing tank to make the lower space larger to increase the storage volume of the take-out box, thereby increasing the take-out amount per degree. However, such a structure not only increases the size of the fermentation treatment apparatus, but also increases the center of gravity and makes it unstable. Further, in the case where the crushed garbage is naturally transported from the garbage crushing section to the processing tank by gravity, if the height of the processing tank is increased, it becomes difficult to take the slope of the transfer pipe.

Accordingly, an object of the present invention is to provide a fermentation treatment apparatus capable of taking out the contents of a fermentation treatment while ensuring good workability and safety.

Another object of the present invention is to provide a fermentation treatment apparatus capable of removing the entire amount of fermentation treatment contents in one operation.

It is another object of the present invention to provide a fermentation treatment apparatus having a small size and a low center of gravity.

Another object of the present invention is to provide a garbage crushing and fermentation treatment apparatus which can easily secure a gradient of a transport pipe for naturally transporting crushed garbage by gravity.

[0011]

SUMMARY OF THE INVENTION In order to solve this problem, a fermentation treatment apparatus according to the present invention comprises a treatment tank in which garbage is fermented, and a treatment tank which is detachably attached to the bottom of the treatment tank. A partition plate that opens downward, and a plurality of at least double units that are installed below the partition plate so as to be able to be sequentially pulled out from the inside and collect the fermentation treatment contents that fall from the processing tank opened by the partition plate. And a take-out box, so that the fermentation processing contents can be divided and taken out into a plurality of take-out boxes.

Thus, the contents of the fermentation treatment can be taken out while ensuring good workability and safety. Further, the entire amount of the fermentation processing contents can be taken out only by a series of pull-out operations of the take-out box. Furthermore, the capacity per box for collecting the fermentation processing contents can be small, and there is no need to install the processing tank at a high position, so that the size and center of gravity of the fermentation processing apparatus can be reduced. And, the gradient of the transport pipe for naturally transporting the crushed food waste by gravity can be easily secured.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is a fermentation treatment apparatus for fermenting garbage and composting the same, wherein a processing tank in which garbage is fermented is provided. A partition plate that is detachably attached to the bottom of the processing tank and opens the processing tank downward, and is installed below the partition plate so that it can be pulled out at least double and sequentially from the inside,
A plurality of take-out boxes for collecting the fermentation treatment contents falling from the treatment tank opened by the partition plate, so that the fermentation treatment contents can be divided into a plurality of take-out boxes and taken out. Since the fermentation processing contents are taken out to the take-out box by removing the plate, there is an effect that the fermentation processing contents can be taken out while ensuring good workability and safety.

Further, since the fermentation processing contents are divided and taken out while sequentially pulling out a plurality of take-out boxes, the entire amount of the fermentation processing contents can be taken out only by a series of taking-out operations of the take-out boxes. It has the action of:

Furthermore, since the fermentation processing contents are taken out by the plurality of stacked take-out boxes, the capacity per box for collecting the fermentation processing contents can be small, and the processing tank can be placed at a high position. Since it is not necessary to install the fermentation treatment device, the fermentation treatment device can be downsized and the center of gravity can be reduced.

Since the treatment tank can be set at a low position in this way, the effect of easily securing the gradient of the transport pipe for naturally transporting the crushed garbage by gravity is obtained. Have.

According to a second aspect of the present invention, there is provided a fermentation treatment apparatus according to the first aspect, wherein a plurality of take-out boxes are connected to each other at a drawer end so as to be separable from each other. Is continuously drawn out, so that the fermentation treatment contents can be easily taken out even when the installation space of the fermentation treatment device is narrow.

According to a third aspect of the present invention, there is provided a garbage pulverizing and fermenting apparatus using the fermenting apparatus according to the first or second aspect.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. In these drawings, the same members are denoted by the same reference numerals, and duplicate description is omitted.

FIG. 1 is an overall configuration diagram showing a garbage crushing and fermentation treatment apparatus according to an embodiment of the present invention, and FIG. 2 is a longitudinal sectional view showing a garbage crushing section in the garbage crushing and fermentation treatment apparatus of FIG. 3 (a) is a sectional view showing a fermentation treatment apparatus in the garbage crushing and fermentation treatment apparatus of FIG. 1, and FIG. 3 (b) is a sectional view of FIG.
FIG. 4 is a cross-sectional view showing the fermentation processing apparatus in a cross section orthogonal to the cross section of (a), FIG. 4 is a block diagram showing a control system in the garbage pulverizing fermentation processing apparatus in FIG. 1, and FIG. 5 is fermentation in the fermentation processing apparatus in FIG. It is explanatory drawing which shows the removal structure of a processing content.

In FIG. 1, a garbage crushing unit 1 similar to a mixer for crushing garbage is installed under a sink of a kitchen sink, and the garbage is pulverized only by mixing a small amount of water into the inputted garbage. Make it transportable. The garbage crushing unit 1 is connected to a fermentation treatment device 4 by a transport path 3. The transport path 3 is made of, for example, a seamless, flexible polyethylene tube having an inner diameter of 10 mm, and the surface roughness (ε / D) of the inner wall surface is set to be smaller than, for example, 0.003. Here, ε is the height of minute irregularities indicating the surface roughness of the inner wall surface, and D is the representative dimension of the tube (in the case of a circular tube, the inner diameter). The representative dimension is obtained by dividing four times the cross-sectional area of the tube by the inner peripheral length. However, the surface roughness is not restricted to the above-mentioned value, and any surface roughness can be used as long as the adhesion of the crushed garbage to the inner wall surface of the transport path 3 can be minimized. The fermentation treatment device 4 is configured to culture microorganisms such as aerobic thermophilic bacteria, mainly Bacillus, and compost the conveyed garbage. A squeeze pump (pressurizing means) 2 is provided between the garbage crushing section 1 and the transport path 3, and the high-viscosity garbage crushed by the garbage crushing section 1 is pushed into the transport path 3. To the fermentation treatment device 4 one after another.

In such a garbage crushing and fermentation treatment apparatus, the fermentation treatment apparatus 4 is arranged outdoors, and the garbage crushing section 1 and the squeeze pump 2 are arranged indoors.

Here, the garbage crushing section 1 of the garbage crushing and fermentation treatment apparatus will be described in detail with reference to FIG.

In FIG. 2, a movable blade 5 is rotatively attached to a garbage crushing section 1 by a motor 6 for crushing garbage introduced from an upper inlet and converting the garbage into high-viscosity garbage. ing. In the case shown, the movable blade 5
Are provided in two stages at two locations in the longitudinal direction of the shaft of the motor 6, each having four blades. The motor 6
Is controlled by the control means 30 as described later.
At a position facing the movable blade 5 on the wall surface of the crushing chamber of the garbage crushing section 1, a fixed blade 7 composed of a projection is provided. The fixed blade 7 is formed in an isosceles triangular cross section so that the cooperation with the movable blade 5 is not lost even if the movable blade 5 rotates clockwise or counterclockwise.

With such a structure, as a first step, the movable blade 5 is jogged by intermittently energizing the motor 6, and vibrations are given to the garbage that has been input, and the vibration is applied between the fixed blade 7 and the movable blade 5. And coarsely crushed at the same time. Next, as a second step, the energization of the motor 6 is made continuous, so that the garbage is crushed by the movable blade 5 and the fixed blade 7 and crushed into fine particles. In addition, it is possible to pulverize in this way only with the movable blade 5 without providing the fixed blade 7 in particular.

A water inlet 8 for feeding tap water into the crushing chamber is formed facing the crushing chamber in which the garbage is crushed. The tap water injected from the water inlet 8 and added to the garbage facilitates the pulverization and adjusts the viscosity. In addition, on the path of tap water reaching the water inlet 8, a solenoid valve 9 for adjusting the amount of water and a constant flow valve 10 for keeping the amount of injected water constant without being affected by water pressure fluctuation are installed. . Further, a garbage discharge port 11 for sending the pulverized high-viscosity garbage to the transport path 3.
Is attached to the bottom of the grinding chamber with an opening.

As described above, the garbage crushing unit 1 shown in FIG.
Rather than flushing garbage to be crushed with a water stream and transferring it to a crushing unit as in a normal disposer, or sending garbage after crushing onto a stream of water, the motor 6 is intermittently energized so that the movable blade 5 is shaken so that the garbage is vibrated and dropped to the bottom, and a small amount of water is contained therein to make a high-viscosity pulverized product. Such a garbage crushing section 1 has a crushing capacity capable of processing 1 kg of garbage per day, and is suitable for household garbage processing.

Next, the fermentation treatment apparatus 4 will be described with reference to FIG. 1 and FIGS. 3 (a) and 3 (b).

In the treatment tank 20 of the fermentation treatment device 4, a garbage water conditioning material which is mixed with the high-viscosity garbage crushed from the conveying path 3 and decomposes the garbage crushed by the fermentation treatment. 13 are loaded. As the garbage water conditioning material 13, in addition to the action of adjusting the water content in the crushed garbage, sawdust having an action of a microbial carrier that inhabits microorganisms for fermentation represented by aerobic thermophilic bacteria and the like. And wood chips are suitable.

In the treatment tank 20, the garbage water conditioning material 13 is provided.
The stirring blade 14 is provided to stir the garbage and the conveyed garbage into a uniform state. Stirring blade 1
The rotation shaft 4 is rotatably supported by the fermentation treatment device 4. The stirring blade 14 is provided with a plurality of blades standing from a rotation shaft, and the tip of the blade is rounded for danger prevention. A sprocket 12a is attached to one end of the rotation shaft of the stirring blade 14. A chain 12b to which the rotational force of the stirring motor 15 mounted on the upper part is transmitted is laid over the sprocket 12a. Thereby, the stirring blade 14 is attached to the sprocket 1
It is rotated with the rotation of 2a.

A heating means 16 is provided at the bottom of the processing tank 20. The heating means 16 is an electric heating surface heater in which electric heating wires are evenly distributed. The heating means 16 adjusts the temperature inside the processing tank 20 to the aerobic thermophilic microorganisms in accordance with the temperature detected by a temperature sensor (not shown). When the water content is temporarily increased due to the high-viscosity garbage crushed from the garbage crushing unit 1 or when washing water flows in, the water is evaporated and the internal temperature is controlled. To a state suitable for fermentation.

An exhaust fan 17 is attached to the upper part of the processing tank 20. The exhaust air is exhausted to exchange fresh air with a mixture of a high-viscosity garbage crushed material and a garbage moisture adjusting material 13. To keep the inside of the processing tank 20 under aerobic conditions.

In order to exhaust gas such as air containing odor, water vapor, and carbon dioxide from the exhaust fan 17 to the sewer pipe 18b, an attachment port of the exhaust fan 17 and the sewer pipe 18b are communicated by an exhaust passage 18. Further, a check valve 19 for preventing odor from flowing back into the treatment tank 20 when a high positive pressure is applied to the inside of the drain pipe 18b is provided near the drain pipe 18b of the exhaust path 18.

Here, a partition plate 41 that can be slid and removed is attached to the bottom of the processing tank 20. Therefore, when the partition plate 41 is removed, the processing tank 20 is opened downward, and the fermentation processing contents 39 (FIG. 5) composed of the composted garbage crushed material and the garbage moisture adjusting material 13 fall. I do.

As described above, a take-out box for collecting the fermentation processing contents 39 falling from the processing tank 20 is provided below the partition plate 41 in which a space is formed by disposing the stirring motor 15 and the like at the upper part. 40 are installed.

As shown in detail in FIG. 5, the take-out box 40 is composed of an inner take-out box 42 and an outer take-out box 43 provided in a double manner.
2. The drawer 43 can be pulled out in this order.
In the present invention, the take-out box 40 may be triple or more. In the case of triple or more, they are sequentially pulled out from the inner box.

Such a fermentation treatment apparatus 4 has a capacity of one per day.
It is suitable for household garbage processing that can perform kg fermentation processing.

Next, the fermentation decomposition of the crushed garbage in the fermentation treatment apparatus 4 will be described. The high-viscosity garbage crushed material mixed with the garbage water conditioning material 13 in the treatment tank 20 is quickly spilled by microorganisms such as aerobic thermophilic bacteria, mainly Bacillus, that inhabit the garbage water conditioning material 13. Decomposes into water, carbon dioxide, ammonia, other inorganic substances, and persistent organic residues. Then, the generated gas component is exhausted by the exhaust fan 17 and discharged to the sewer through the exhaust path 18 in order to prevent the odor from spreading. As a result, in the fermentation treatment device 4, compost, which is an organic matter residue stabilized by decomposition, is generated.

Microorganisms such as aerobic thermophilic bacteria mainly belonging to the genus Bacillus inhabit the garbage water conditioning material 13, but the genus Bacillus, which is a representative of the aerobic thermophilic bacteria, is commonly used in soil. It is a very common bacterium present in the soil, and greatly contributes to the decomposition activity in the early stage of compost fermentation. A major feature of the genus Bacillus is its ability to form spores. Bacillus bacteria form spores when the surrounding environment becomes severe. When the environment is improved, it germinates again and begins to proliferate vigorously. Spores are thought to be like the seeds of a so-called microorganism, and have high heat resistance. Such microorganisms centering on the genus Bacillus can continue to survive in an environment of 50 ° C to 90 ° C, and the highest activity is around 50 ° C to 65 ° C. In the temperature range of 70 ° C. or more, the fermentation decomposition rate is reduced, but insects and the like are not generated in the tank, and weeds, viruses, parasites, harmful microorganisms and the like can be inactivated.

In addition, the fermentation treatment apparatus 4 needs a water environment suitable for its inhabitation in principle, because it performs treatment using microorganisms such as Bacillus bacteria. It is necessary to keep the water content of the mixture included in the range of 50% to 60%. If the water content is below this range, the water required for the biological activity of the microorganisms will be insufficient, and the fermentation rate will be reduced. On the other hand, if the water content exceeds this range, oxygen to be supplied by stirring will be insufficient, and the inside of the tank will be anaerobic, and anaerobic microorganisms will propagate to generate strong odor.

Here, the water content is obtained by dividing the amount of water contained in the garbage and the garbage water conditioner 13 by the sum of the dry weight of the garbage and the garbage water conditioner 13 and the water content. .
In the present embodiment, a temperature sensor is used as a sensor for measuring the water content, and the water content is calculated by conversion.

Next, the squeeze pump 2 which is a pressure feeding means for conveying the high-viscosity garbage crushed in the garbage crushing section 1 to the fermentation apparatus 4 will be described.

The squeeze pump 2 is also called a tube pump. The squeeze pump 2 is a pump tube made of an elastic material such as natural rubber and inverted in a substantially U-shape, a rotor having a plurality of rotatable rollers arranged on a circumference, and It has a motor to rotate. Then, when the rotor rotates and the roller presses the arc-shaped pump tube, the closed position of the pump tube by the roller moves in the transport direction,
The crushed garbage in the pump tube is squeezed out to the fermentation treatment device 4. In the present invention, the pumping means does not necessarily need to be the squeeze pump 2, but the garbage crushed material is pressure-fed by moving while pressing and blocking the passage of the garbage crushed material. I just need.

Although the squeeze pump 2 is a positive displacement pump as described above, no valve mechanism is provided therein, and the squeeze pump 2 has a structure in which a plurality of rollers successively press and squeeze the pump tube, so that pulsation is relatively small. Pumping is possible. In addition, the squeeze pump 2 does not need any special operation for inhalation because of self-priming.

The high-viscosity garbage crushed in the garbage crushing section 1 overcomes the pipe resistance of the transport path 3 connected to the discharge side by such a squeeze pump 2 and is pressure-fed to the fermentation treatment apparatus 4. Is done. Since the portion of the pump tube through which the crushed refuse passes and the rotor serving as the drive-side member are separated via the pump tube wall, the rotor serving as the drive-side member does not come into contact with the garbage refuse. This increases the degree of freedom in design. Further, since the discharge amount can be easily controlled by changing the rotation speed of the motor, even when the pump tube is deteriorated, it can be easily returned to the initial performance by replacing it.

It should be noted that a positive displacement pump, such as a diaphragm pump, a plunger pump, or a snake pump, can be used as another pumping means for realizing such a transport mode. However, although they can produce high pressure, they have the disadvantage of large pulsation and vibration. Further, the garbage crushing unit 1 may be pressurized by an air pump or the like as a pressurizable container, or may be conveyed by a pressure difference from the conveying path 3 by depressurizing the fermentation treatment apparatus side with a vacuum pump or the like. These all have the same operation as the squeeze pump 2.

Next, the tube which is the transport path 3 will be described. As the tube, a tube having an inner diameter of 10 mm is selected assuming a household garbage disposal apparatus that processes about 1 kg of garbage per day. However, the inner diameter of the tube is suitably 5 mm or more, as described later, and is more preferably in the range of 5 mm to 20 mm. The material of the tube may be a resin such as polytetrafluoroethylene or polyamide in addition to polyethylene. In each case, a similar effect can be obtained. When a tube serving as the transport path 3 is manufactured from these resins, flexibility is given and the surface roughness (ε / D) of the inner wall surface easily becomes smaller than 0.003.

Next, a control mechanism in the garbage crushing and fermentation treatment apparatus of the present embodiment will be described.

In FIG. 4, the control mechanism of the garbage crushing and fermenting treatment apparatus has a control means 30 composed of a microcomputer, a memory and the like. The garbage crushing unit 1 has a crushing motor driving means 31 for driving the motor 6 and an electromagnetic valve driving means 36 for driving the electromagnetic valve 9, and the squeeze pump 2 has a pressure feeding motor driving means 32 for driving the motor 43.
However, the fermentation treatment apparatus 4 is provided with a stirring motor driving unit 33 for driving the stirring motor 15, a heating driving unit 34 for driving the heating unit 16, and a fan driving unit 35 for driving the exhaust fan 17, respectively. Then, the crushing motor driving means 31, the pressure feeding motor driving means 32, the stirring motor driving means 33, the heating driving means 34, the fan driving means 3
5. The electromagnetic valve driving means 36 is controlled by a command from the control means 30. The control means 30
Is connected to a timer 37 for measuring a predetermined time.

According to such a control mechanism, first, the control means 30 drives the solenoid valve driving means 36 to open the solenoid valve 9 in response to an input signal from the operation switch. Thereby, water is sent to the constant flow valve 10 through the electromagnetic valve 9. Since the constant flow valve 10 always discharges a constant amount of water even if the pressure fluctuates, the required amount of water can be easily and accurately supplied by controlling the operation time of the solenoid valve driving means 36. You. The control means 30 drives the electromagnetic valve driving means 36 and at the same time causes the timer 37 to start counting time. When the timer 37 counts a predetermined time corresponding to the supply flow rate stored in the control unit 30, the control unit 30 drives the electromagnetic valve driving unit 36 to stop the discharge of water. Thereby, a small amount of water is supplied from the constant flow valve 10 into the garbage crushing unit 1.

The control means 30 drives the electromagnetic valve driving means 36 as described above, and at the same time, drives the pulverizing motor driving means 31 to rotate the rotary blade 5 to start the operation of the garbage pulverizing section 1. When the time for sufficiently pulverizing the garbage is measured by the timer 37, the control means 30 drives the pumping motor driving means 32 to start the operation of the squeeze pump 2, and Start pumping.
At this time, the operation of the garbage crushing unit 1 is continued.

A series of operations of the garbage crushing and fermentation treatment apparatus having such a configuration will be described. First, when the user puts garbage into the garbage crushing unit 1 and turns on the operation switch, the control unit 30 operates the electromagnetic valve driving unit 36 with reference to the time from the timer 37. Then, the solenoid valve 9 is set to the open position, and tap water is injected into the garbage crushing unit 1 from the water inlet 9 in a predetermined amount, for example, 0.2 to 1.0 times the weight of the garbage. At the same time, the control means 30 drives the crushing motor driving means 31 to start the rotation of the movable blade 5 and to start the crushing of garbage. Then, by the timer 37,
The crushing is continued for a predetermined time until the garbage becomes sufficiently fine.

When a predetermined time has elapsed after the start of the pulverization, the control means 30 drives the pressure-feeding motor drive means 32 to send the high-viscosity raw garbage pulverized by the squeeze pump 2 to the transport path 3 which is a tube. During the pressure feeding, it is appropriate to operate the squeeze pump 2 while keeping the movable blade 5 rotating without stopping the operation of the motor 6 of the garbage crushing unit 1. This is because it is possible to prevent the pulverized material from being unnecessarily separated or settled by the rotation of the movable blade 5, and to efficiently convey the pulverized material as a homogeneous pulverized material.

Simultaneously with the start of the operation of the squeeze pump 2, the control means 30 operates the stirring motor driving means 33 to start the rotation of the stirring blades 14 of the fermentation treatment apparatus 4. The crushed garbage sent out by the squeeze pump 2 is
The raw garbage moisture adjusting material 13 loaded in the processing tank 20 is sufficiently mixed. The driving of the stirring blade 14 is as follows.
Rather than being performed continuously, it is performed intermittently and periodically at a rate of several minutes per hour.

After a lapse of a predetermined time during which the garbage is completely crushed and conveyed, the control means 30 temporarily stops the operation of the movable blade 5 of the garbage crushing section 1 and the squeeze pump 2, and then proceeds to the cleaning operation. enter.

Next, the washing operation of the garbage crushing and fermentation treatment apparatus according to the present embodiment will be described.

Squeeze pump 2 inside garbage crushing section 1
Inside the transport path 3 which is a tube, a large amount of residue remains after the garbage is transported. Particularly, inside the garbage crushing section, considerable deposits remain due to scattering of the crushed garbage. If this residue is left as it is, it is putrefied by the action of bacteria and becomes a source of foul odor and sticks and deposits as scum, which leads to deterioration of the environment and inoperability. Therefore, maintenance for cleaning such adhesion residue is required.

The control means 30 drives the solenoid valve driving means 36 as a first cleaning step to clean the residue,
Once the water inlet 8 is opened, a small amount of water of about 0.1 to 0.2 times the space volume of the crushing section of the garbage crushing section 1 is injected.
The control means 30 operates the rotary blade 5 for a predetermined time simultaneously with the injection of water. Thereby, the scattered crushed material is sufficiently washed away.

Subsequently, when the deposits are removed by the washing, the control means 30 operates the squeeze pump 2 to send the washing water to the transport path 3.

Here, the washing water is used to wash the inside of the squeeze pump 2 and the conveying path 3. However, since the washing water has a low viscosity and contains a solid content, it is difficult to form a continuous flow. It cannot be washed well. In addition, the washing water cannot be sufficiently conveyed to the fermentation treatment device 4.

Therefore, as a second cleaning step, the transport path 3
The control means 30 opens the water inlet 8 again to carry out the washing of the water and the transfer of the washing water to the fermentation treatment apparatus 4.
Inject 2.0 times water. Subsequently, the control means 30 operates the squeeze pump 2 and cleans the inside of the squeeze pump 2 and the transport path 3 with the water thus newly injected.
It is desirable that the rotation speed of the squeeze pump 2 at this time be higher than when the crushed garbage is pumped. This is because the washing water has a low viscosity, but a continuous flow can be generated by increasing the number of revolutions, that is, the transport speed, and the washing efficiency increases as the washing water is sent at a higher speed.

The washing water has a much lower viscosity than the crushed garbage, and the squeeze pump 2 is used in the first washing step.
The interior of the transfer path 3 is cleaned by increasing the number of revolutions and increasing the pressure without increasing the motor load because the inside of the transfer path 3 has a small solid content. Washing after grinding with a conventional disposer is performed with a water amount of 20 times or more the weight of garbage, but in the present embodiment, in the first and second washing steps described above, an overwhelmingly small amount is used. Cleaning can be performed neatly with water.

Here, the procedure for taking out the generated fermentation contents 39 from the processing tank 20 will be described in detail with reference to FIG. In addition, generally, the fermentation processing content 39 to be taken out is about 20 to 30 L, but in the present embodiment, a case where 30 L which is the take-out capacity when the inside of the treatment tank 20 is full will be described. The height of the take-out box 40 is 10 cm, and the effective volume is 18 cm.
L. However, the present invention is not limited to these numerical values.

In order to take out the fermentation processing contents 39, first, the partition plate 41 is pulled out to open the processing tank 20 downward. Then, when the stirring motor 15 is driven by the control means 30, the fermentation processing contents 39 smoothly fall from the processing tank 20 into the inner take-out box 42.

In this way, after the take-out operation with stirring for about one minute is completed, the take-out box 42
Is pulled out to the drawer end where the load becomes heavy due to the locking by the concave and convex fitting of two members (here, the take-out box 42 and the take-out box 43) as seen in a commercially available costume case. Here, since the take-out box 40 is doubled and the inner take-out box 42 is pulled out as described above, the fermentation treatment contents 39 that have dropped first are taken out together with the take-out box 42. At this time, since the take-out box 42 is fitted into the take-out box 43 at the end of the drawer, the two are in a state of being separable from each other. With such a connection structure, the take-out box can be continuously pulled out, so that the fermentation processing contents 39 can be easily taken out even when the installation space of the fermentation treatment device 4 is narrow. However, the uneven fitting structure may not be used. In this case, they are individually drawn out.

The fermentation processing contents 39 remaining in the processing tank 20
In order to take out, the stirring operation for one minute is started again at the same time as the inside take-out box 42 is pulled out. As a result, the fermentation processing contents 39 fall into the outer take-out box 43.

Since about 17 L of the fermentation processing contents 39 have already been taken out of the drawn-out inner take-out box 42, the remaining 13 L is taken out by the outer take-out box 43. The outer take-out box 43 is pulled out by being connected to the inner take-out box 42 by the above-mentioned concave and convex fitting. However, the take-out box 42 can be lifted to release the connection between the two and taken out separately.

As described above, according to the fermentation processing apparatus 4 according to the present embodiment, the fermentation processing contents 39 are taken out to the take-out box 40 by removing the partition plate 41, so that good workability and safety are ensured. Fermentation processing contents 39
Can be taken out.

Further, since the fermentation processing contents 39 are divided into the inner take-out box 42 and the outer take-out box 43 and sequentially taken out, the entire amount of the fermentation processing contents 39 can be taken out only by a series of pull-out operations. Can be taken out.

Further, as described above, the plurality of take-out boxes 40
The fermentation processing contents 39 are taken out by the above method, so that the capacity per box for collecting the fermentation processing contents 39 can be small, and the processing tank 20 does not need to be installed at a high position. The size and the center of gravity of the device 4 can be reduced. Here, it has already been described that the take-out box 40 can be tripled or more, but in this case, the capacity per box becomes smaller, and the processing tank 20 can be installed at a lower position. As a result, the center of gravity of the entire fermentation treatment device 4 is further lowered, and the stability is increased.

Since the treatment tank 20 can be set at a low position in this manner, the gradient of the transport pipe for naturally transporting the crushed garbage by gravity can be easily secured.

After the operation of taking out the fermentation processing contents 39 is completed, the drawn-out partition plate 41 is pushed back to the original position, whereby the bottom surface of the processing tank 20 is closed.

In this embodiment, the fermentation treatment apparatus 4 is used to reduce the amount of garbage input and to increase the fermentation treatment speed.
A garbage crushing section 1 for crushing garbage and a squeeze pump 2 for transporting crushed garbage are provided at a stage preceding the garbage. However, the present invention can also be applied to a fermentation treatment apparatus that performs a fermentation treatment by directly adding garbage to the fermentation treatment tank 4.

[0074]

As described above, according to the present invention, the contents of the fermentation treatment are taken out by removing the partition plate into the take-out box, so that the contents of the fermentation treatment can be obtained while ensuring good workability and safety. An effective effect of being able to take out is obtained.

Further, according to the present invention, since the fermentation processing contents are divided and taken out while sequentially pulling out a plurality of take-out boxes, the entire amount of the fermentation processing contents can be obtained only by a series of taking-out operations of the take-out boxes. An effective effect of being able to take out is obtained.

Further, according to the present invention, since the fermentation processing contents are taken out by the plurality of stacked take-out boxes, the capacity per box for collecting the fermentation processing contents can be small. Since the treatment tank does not need to be installed at a high position, an effective effect of reducing the size and lowering the center of gravity of the fermentation treatment apparatus can be obtained.

In particular, by stacking more take-out boxes, the capacity per box becomes smaller and the processing tank can be installed at a lower position, so that the center of gravity of the entire fermentation processing apparatus is further lowered. As a result, an effective effect of increasing the stability is obtained.

According to the present invention, the processing tank can be installed at a low position in this way, so that the slope of the transport pipe for naturally transporting the crushed garbage by gravity can be easily secured. An effective effect is obtained.

If a plurality of take-out boxes are connected to each other at the drawer end so as to be separable from each other, the take-out boxes are continuously drawn out, so that even if the installation space of the fermentation treatment apparatus is narrow, the contents of the fermentation treatment can be easily obtained. Can be obtained.
