DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved garbage disposal apparatus for reducing the amount of garbage generated from ordinary households or restaurants by decomposing the garbage with microorganisms or the like.

[0002]

2. Description of the Related Art In a conventional garbage processing apparatus of this type, kitchen garbage is only primary fermentation, and the kitchen garbage or base material after treatment is in a compost state, and cannot be immediately supplied to crops as fertilizer. As shown in Japanese Patent Application Laid-Open No. 7-51655, a method has been proposed in which one tank is roughly separated and another fermentation decomposition function is provided. Was difficult.

[0003]

In the conventional garbage disposal apparatus having the above-described structure, it takes only a long time to produce compost, and it takes a long time to produce a fertilizer. Also, since the final compost state is a little dry, there is a problem that secondary fermentation cannot be performed as it is, and when a large amount of water is added to a part of the compost state, the part becomes a dumpling state. There was a problem that stirring was stopped while fermentation decomposition was reduced.

[0004] In addition, there is another problem that when the evaporation of water due to the heat of secondary fermentation is completely exhausted, the water in the secondary fermenter runs short. Further, the stirring of the secondary fermentation tank requires the supply of oxygen to the secondary fermentation product, but there is a problem that the water is insufficient when the ventilation is excessive. Also, if the stirring of the secondary fermenter is stirred regardless of the fermentation decomposition, there is a problem that too much water evaporates and oxygen is supplied excessively.If the fermentation temperature is too high, the bacteria will die and fermentation will decrease. There was a problem.

And 3, temperature sensors 28 and 29, a water sensor 30 for detecting the presence or absence of water in the water storage tank 19, and various switches 31 are connected.

Is connected. 39 is a power supply unit.

In FIG. 1, only the exhaust fan 26 is provided in the exhaust duct 23. In FIG. 4, however, the exhaust fan 26 is an exhaust fan dedicated to the primary fermenter 2 and a fan dedicated to the secondary fermenter 3. An example in which an exhaust fan 36 driven by a driving unit 37 is provided is shown.

FIGS. 5A and 5B are diagrams showing the timing of supply and exhaust and stirring of the secondary fermentation tank 3, wherein FIG. 5A shows the drive timing of the stirring blade 10, and FIG. 5B shows the drive timing of the exhaust fan 36. Respectively show the waveforms. As is apparent from these waveforms, the exhaust fan 36 is driven during and before and after the driving of the stirring blade body 10.

FIG. 6 shows the stirring control based on the temperature control. As is clear from FIGS. 6A and 6B, the temperature in the fermenter is not higher than the lower limit temperature Tmin. The relationship of T1> T2 is established between the stirring period T1 and the stirring period T2 at or above the upper limit temperature Tmax, and it is understood that T1 is a considerably longer period than T2.

FIG. 7 is a diagram showing an operation flow of the garbage disposal in the secondary fermentation tank 3 in a standby state (step S).
In 1), the microcomputer unit 27 detects the presence or absence of water supply from the amount of water stored in the water storage tank 19 through the water sensor 30 (step S2), and upon detecting water, supplies a drive signal to the motor drive buzzer 34 to stir. The motor 9 is driven to rotate the second stirring blade 10 via the clutch mechanism and the speed reducer 13 to stir the garbage in the secondary fermentation tank 3 together with the culture substrate (step S3).

On the other hand, if NO is determined in step S2, it is determined in step S4 whether or not the time is t1 before the stirring operation.
To drive the exhaust fan 36 (step S5). Then, the driving of the exhaust fan 36 is stopped at t2 after the end of the stirring operation (steps S6 and S7).

At this time, the temperature sensor 29 monitors the temperature in the secondary fermentation tank 3, and when the temperature falls below the lower limit set value (step S8), the stirring cycle is set to T shown in FIG.
The rotation of the stirring motor 9 is reduced by controlling the motor driving unit 34 so as to be 1 and the stirring cycle is set to T2 when the temperature in the tank 3 becomes equal to or higher than the upper limit set value (step S10). The rotation of the stirring motor 9 is increased by controlling the motor drive unit 34 (step S11). In the control of the stirring cycle based on the temperature in the fermenter 3, at a temperature between the lower limit set value and the upper limit set value, stirring is performed at a cycle of T, and the stirring is changed according to each temperature to evaporate water. Is controlling.

During the stirring operation, the microcomputer 27 detects the necessity of water supply by the input of a temperature sensor or the like (step S12). When it is determined that the water supply is necessary, the microcomputer 38 drives the alarm 38. A water supply warning is output (step S13). By such control, active secondary fermentation is maintained, and the time for fertilization is shortened.

The above is the operation flow of the garbage disposal in the secondary fermentation tank 3. Before the garbage disposal in the secondary fermentation tank 3, the garbage disposal is executed in the primary fermentation tank 2. . In the primary fermenter 2, the stirring wings 5 are rotated via the clutch mechanism and the speed reducer 8 by the driving of the stirring motor 9, thereby stirring the raw garbage and the culture substrate, thereby fermenting and degrading the raw garbage. To process.

When the fermentation decomposition ability in the primary fermenter 2 decreases, the separator 3a is opened by operating the separator 3a, and the composted garbage and the culture substrate in the primary fermenter 2 Drop it into the secondary fermenter 3. Then, in the secondary fermenter 3, the above-described processing operation is performed to further ferment and decompose the organic matter that has not been fermented and decomposed in the primary fermenter 2, so as to approach a mature fertilizer.

In the water supply apparatus shown in FIGS. 2 and 3 according to the present invention, the lid 4 on the upper surface of the main body 1 is opened, and water is injected through the water inlet 20. The injected water is stored in a water storage tank 19 and is supplied to the secondary fermentation tank 3 from water supply ports 22 provided in a water supply pipe 21. As in the present invention, the water supply port 2
Since the water supply amount per unit time can be limited to a small amount by reducing the diameter of 2, the primary treated garbage and the culture substrate in the secondary fermentation tank 3 are stirred by stirring the inside of the secondary fermentation tank 3. Water can be uniformly supplied to the mixture. In addition, water inlet 2
If the structure is such that water overflowing from zero flows out of the main body 1, a certain amount of water can be supplied. This is because in the secondary fermentation decomposition, active fermentation decomposition can be performed with appropriate water.

In the above-mentioned water supply device, when the water sensor 30 detects that water has been injected into the water storage tank 19, the rotational force of the stirring motor 9 is reduced by the operation of the clutch mechanism via the speed reduction mechanism 13 in the secondary fermentation tank. The garbage in the secondary fermentation tank 3 and the culture substrate are started to be stirred. Since the water sensor 30 detects not only the water injection into the water storage tank 19 but also the disappearance of the water, the stirring is performed after the water is supplied until the water disappears. Alternatively, it can be operated only for a certain period of time after the water runs out. Thereby, water can be uniformly supplied into the secondary fermentation tank 3 and the power consumption can be reduced.

In the present invention, an exhaust duct 23 is provided,
By driving the exhaust fan 26 provided in the exhaust duct 23, the garbage in both fermenters 2 and 3 and the moisture and gas generated by the fermentation decomposition of the culture substrate are exhausted and new oxygen is supplied. It has become. Since the secondary fermenter 3 requires a certain degree of humidity (moisture), it may or may not require a large amount of ventilation. In addition, a large amount of ventilation is required for drying at the final stage. When the fermentation decomposition becomes quite active, some ventilation is required because water evaporation and gas generation increase.
As described above, if the ventilation (exhaust) amount is varied in accordance with the fermentation state or condition, the effect of promoting fermentation decomposition and fertilizing the fertilizer is great, and the power consumption is reduced.

In particular, in the present invention, as shown in FIG. 5, attention is paid to the timing of this exhaust and stirring, and the moisture and gas generated by the fermentation decomposition are stirred into the air in the secondary fermentation tank 3. Released. In particular, immediately after stirring, a large amount of discharge is generated as compared with other times. Also, the supply of oxygen to the culture substrate is performed by stirring, so that the exhaust fan 26
Starts the operation before the stirring operation by the stirring blade body 10, exhausts the air in the secondary fermentation tank 3 and takes in the air containing oxygen so that the supply of oxygen at the time of stirring is not hindered. After the stirring operation is completed, the exhaust is continued for a while, and a large amount of water or gas released by the stirring is exhausted to maintain the environment in the secondary fermentation tank 3 more appropriate. Thereby, fermentation decomposition is activated and power consumption is reduced.

In the present invention, as shown in FIG. 6, the stirring operation is operated according to the temperature in the fermenters 2 and 3. The lower limit temperature Tmin and the upper limit temperature Tmax are set in the primary and secondary fermenters 2 and 3, and the temperatures of the fermenters 2 and 3 are detected by the temperature sensors 28 and 29,
When the temperature is equal to or lower than the lower limit temperature Tmin, it is considered that the fermentation decomposition is inferior. Therefore, the amount of garbage to be introduced is small, or the water content is insufficient. By thus elongating the stirring cycle, the evaporation of water can be suppressed.

On the other hand, if the temperature in the fermenter exceeds the upper limit temperature, there is a fear that the bacteria that are undergoing fermentation and decomposition may die.
The stirring cycle is shortened to T2 to prevent the temperature from rising and to promote the evaporation of water. Thereby, the active fermentation decomposition can be maintained, and when the fermentation decomposition becomes poor, the fermentation decomposition can be promptly changed to the active direction. Therefore, power consumption by fermentation heat can be reduced,
Active fermentation decomposition can be sustained.

Further, in the present invention, as shown in the operation flow of FIG. 7, water is required for the fermentation decomposition during the garbage stirring operation, and the evaporation of the water is controlled. Moisture is lost by the exhaust, and when the moisture decreases, fermentation decomposition decreases. Therefore, when the temperature does not rise even when the control based on the stirring period or the like is performed, a warning is issued by the alarm 38 as a shortage of water, and the supply of water is encouraged. As a result, active fermentation decomposition can be maintained, and the fertilizer fertilizer can be shortened and the fertilizer with higher maturity can be produced.

In the present invention, the temperature sensor 30 detects the fermentation temperature in the secondary fermentation tank 3 and determines that the secondary fermentation has been completed. The drying process is started by the drive control. The inside of the secondary fermentation tank 3 is heated to the set temperature by the heater 30 to perform stirring in a short cycle, and the exhaust fan 36 is controlled so that the maximum exhaust amount is obtained, and drying is performed in a short time. When the drying is completed, an alarm is issued assuming that the fertilization has been completed. This alarm is issued by the annunciator 38.
It may be a display such as an ED or a sound such as a buzzer.
