FIG. 7 is an explanatory view showing a state in which the raw garbage water conditioning material according to another embodiment of the present invention is charged into a fermentation treatment tank.

In FIG. 1, a garbage crushing means 1 similar to a mixer for crushing garbage is installed under a sink of a kitchen sink, and crushes the garbage by merely mixing a small amount of water into the garbage. Make it transportable. The garbage crushing means 1 is connected to a fermentation treatment tank 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 tank 4 is configured to culture microorganisms such as aerobic thermophilic bacteria, mainly Bacillus, and compost the conveyed garbage. A squeeze pump (pressure feeding means) 2 is provided between the garbage crushing means 1 and the transport path 3, and the high-viscosity garbage crushed by the garbage crushing means 1 is pushed into the transport path 3 to be crushed. To the fermentation tank 4 one after another.

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

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

In FIG. 2, the garbage crushing means 1 has a movable blade (pulverizing means) 5, which is rotated by a motor 6, for crushing the garbage supplied from the upper inlet and converting the garbage into high-viscosity garbage. Mounted freely. In the case shown in the figure, the movable blades 5 are provided in two stages at two positions in the longitudinal direction of the shaft of the motor 6, and each has four blades.
The motor 6 is controlled by the control unit 30 as described later. At a position facing the movable blade 5 on the wall surface of the crushing chamber of the garbage crushing means 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.

According to 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 inputted garbage, 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 where 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.

Thus, the illustrated garbage crushing means 1
Instead of flushing garbage to be crushed with a water stream and transferring the garbage to the crushing section as in a normal disposer, or sending out garbage after crushing in a stream of water, the motor 6 is intermittently energized. The movable blade 5 is moved slightly to vibrate the garbage so that the garbage falls to the bottom, and a small amount of water is contained therein to make a high-viscosity pulverized product. Such a garbage crushing means 1 has a crushing capacity capable of processing 1 kg of garbage per day, and is suitable for household garbage disposal.

Next, the fermentation treatment tank 4 will be described with reference to FIGS. 1 and 3A and 3B. In a treatment tank 20 formed in the fermentation treatment tank 4, a garbage water conditioning material that is mixed with the high-viscosity garbage crushed material sent from the transport path 3 and decomposes the garbage crushed material by 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 processing 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
Reference numeral 4 denotes a rotatable shaft rotatably supported by the fermentation treatment tank 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 is transmitted extends over the sprocket 12a. This allows
The stirring blade 14 is rotated with the rotation of the sprocket 12a.

The 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 by the high-viscosity garbage crushed from the garbage crushing means 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, and the inside 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.

The fermentation tank 4 has a capacity of 1 k / day.
It is suitable for household garbage disposal capable of fermenting g.

Next, the fermentation decomposition of the crushed garbage in the fermentation tank 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 hardly decomposable 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, compost, which is an organic residue stabilized by decomposition, is generated in the fermentation treatment tank 4.

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.

Further, the fermentation treatment tank 4 needs a water environment suitable for its inhabitation on the principle that treatment using microorganisms such as Bacillus bacteria is required. 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 by the garbage crushing means 1 to the fermentation treatment tank 4 will be described.

The squeeze pump 2 is also called a tube pump, and includes a pump tube inverted in a substantially U shape, a rotor having a plurality of rotatable rollers arranged on a circumference, and a motor unit for rotating the rotor. . Then, when the rotor rotates and the roller presses the arc-shaped pump tube held in the case, the blockage of the pump tube by the roller moves in the transport direction, and the crushed garbage in the pump tube moves. Is squeezed out toward the fermentation tank 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 by the garbage crushing means 1 is pressure-fed to the fermentation treatment tank 4 by such a squeeze pump 2 overcoming the pipe resistance of the transport path 3 connected to the discharge side. Is done. Further, since the portion of the pump tube through which the garbage crushed material passes is separated from the rotor serving as the driving side member via the pump tube wall, the rotor serving as the driving side member does not contact the garbage crushed material. Therefore, the degree of freedom of design increases. Further, the discharge amount can be easily controlled by changing the number of revolutions of the motor unit, and 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 also be used as another pumping means for realizing such a transport mode. However, these pumps can generate high pressure, but have the disadvantage of large pulsation and vibration. Further, in addition to this, the garbage crushing means 1 may be pressurized by an air pump or the like as a pressurizable container, or the fermentation treatment tank may be conveyed by reducing the pressure on a vacuum pump or the like by a pressure difference from the conveyance path. Good. In any case, the same operation as the squeeze pump 2 can be achieved.

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. Garbage crushing means 1
The squeeze pump 2 includes a crushing motor driving unit 32 that drives a motor unit and a crushing motor driving unit 32 that drives a motor unit.
However, the fermentation tank 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. 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 35,
The solenoid valve driving means 36 is controlled by a command from the control means 30. Note that a timer 37 for measuring a predetermined time is connected to the control means 30.

According to such a control mechanism, first, the control means 30 drives the solenoid valve driving means 36 to open the solenoid valve 9 according to the 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. As a result, a small amount of water is supplied from the constant flow valve 10 into the garbage crushing means 1.

The control means 30 drives the electromagnetic valve driving means 36 and simultaneously drives the crushing motor driving means 31 to rotate the rotary blade 5 to start the operation of the garbage crushing means 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 means 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 means 1 and turns on the operation switch, the control means 30 operates the electromagnetic valve driving means 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 means 1 from the water inlet 8 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,
Start crushing the garbage. Then, the pulverization is continued by the timer 37 for a predetermined time until the garbage becomes sufficiently fine.

When a predetermined time has elapsed after the commencement of the comminution, the control means 30 drives the pressure-feeding motor drive means 32 and sends out the high-viscosity garbage crushed by the squeeze pump 2 to the transport path 3 which is a tube. At the time of pressure feeding, the operation of the motor 6 of the garbage crushing means 1 is not stopped,
It is appropriate to operate the squeeze pump 2 while rotating the movable blade 5. 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.

At the same time as the operation of the squeeze pump 2 is started, the control means 30 operates the stirring motor driving means 33 to start the rotation of the stirring blades 14 of the fermentation treatment tank 4. As a result, the crushed garbage discharged by the squeeze pump 2 is sufficiently mixed with the garbage moisture adjusting material 13 loaded in the processing tank 20. The driving of the stirring blade 14 is not performed continuously, but is performed intermittently and periodically at a rate of about several minutes per hour.

After a lapse of a predetermined time during which the garbage is completely crushed and transported, the control means 30 sets the garbage crushing means 1
The operation of the movable blade 5 and the squeeze pump 2 is temporarily stopped,
Subsequently, the cleaning operation starts.

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

Many residues remain after the garbage is conveyed inside the garbage crushing means 1, inside the squeeze pump 2, and inside the transfer path 3 which is a tube. In particular, one of the garbage crushing means
Inside, considerable deposits remain due to scattering of crushed garbage. If this residue is left as it is, it is putrefied by the action of bacteria and becomes a source of offensive odor and sticks and deposits as scum, leading to deterioration of the environment and inoperability. Therefore, maintenance for cleaning such adhesion residues 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 means 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 transferred to the fermentation treatment tank 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 tank 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.

Next, the processing procedure and the charging procedure of the raw garbage water adjusting material 13 to be charged into the fermentation tank 4 will be described.

The garbage water conditioning material 13 of the present embodiment is
It consists of a cedar sawdust adjusting material main body having a particle size of, for example, about 0.1 mm to 10 mm, and a biodegradable plastic bag filled with the adjusting material main body (see FIG. 5). Usually, it is stored in a take-out box (not shown) at the lower part of the fermentation treatment tank 4, as shown in FIG. The raw garbage water conditioning material 13 at the upper part of the fermentation treatment tank 4 is directly charged together with the bag from the input port 4a. At this time, the size of the input port 4a is, for example, 15 cm in length and 20 c in width.
m, and the garbage water conditioning material 13 has an input port 4 of this size.
The size is such that it can be inserted into a with a margin.

After the raw garbage moisture adjusting material 13 is charged, the bag is broken by rotating the stirring blade 14, and the adjusting material main body is diffused into the processing tank 20. Since the broken bag is made of biodegradable plastic, it is completely decomposed after about one month.

As shown in FIG. 6, a readily decomposable organic substance such as starch paste is used as an adhesive material as the raw garbage water conditioning material 13, and the particle size of the material is adjusted to, for example, 0.1. An adjusting material main body such as cedar sawdust having a size of about 1 mm to 10 mm may be compression molded into a rectangular parallelepiped having a length of 10 cm, a width of 15 cm, and a height of 25 cm. At this time, the dry weight of the starch paste used is only about 20% of the dry weight of the sawdust to be bonded, and the lightness of the garbage moisture adjusting material 13 is not impaired as a whole.

In place of such a readily decomposable organic substance, an easily water-soluble adhesive material may be used to compress and mold sawdust.

The garbage water conditioning material 13 formed by compression molding using such an adhesive material is also usually provided at the lower part of the fermentation treatment tank 4, similarly to the garbage water conditioning material 13 obtained by packing the adjustment material body in a bag. It is stored in a retrieval box. Then, when the garbage crushing and fermentation treatment apparatus is installed or when the garbage moisture adjusting material 13 is replaced, the whole block is directly fed from the inlet 4a.

If the size of the block forming the garbage water conditioning material 13 is 0.1 cubic centimeter or more, it does not fly in the air and can be easily handled. Therefore, the storage space and shape,
It can be processed to any size according to the size and shape of a.

Note that the block shape of the garbage water content adjusting material 13 may be any shape, and does not necessarily have to be a rectangular parallelepiped as in the present embodiment. However, for efficient packing in a cardboard box or the like or for efficient storage in a storage space, a rectangular parallelepiped is preferable.

[0072]

As described above, according to the present invention, the raw garbage moisture adjusting material can be introduced into the fermentation treatment tank as it is, so that there is an effective effect that the adjusting material main body is not scattered at the time of introduction. can get.

Further, according to the present invention, since the raw garbage moisture regulator can be charged as it is, an effective effect of being able to easily perform the charging operation into the fermentation treatment tank is obtained.

According to the garbage moisture adjusting material in which the adjusting material main body is compression-molded using an adhesive material, it is not necessary to additionally include moisture, so that the garbage moisture adjusting material becomes lightweight and easy to handle. Is obtained.
