[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cocoon treatment apparatus for treating cocoons with microorganisms or the like.
[0002]
[Prior art]
It is important to maintain an environment suitable for the activity of microorganisms in an organic substance processing apparatus that decomposes organic substances by microorganisms cultured on a carrier. Therefore, conventionally, an air supply unit that takes outside air into the processing tank and a heating unit that heats the inside of the processing tank are provided, and the air amount and moisture amount in the processing tank are appropriately maintained by the air supply unit and the heating unit. At the same time, the inside of the treatment tank is kept at the target temperature.
[0003]
As the heating means, a panel heater in which a heater core wire is embedded in a sheet-like base material is arranged on the outer wall of the processing tank, and a heating apparatus with a simple configuration that heats the inside of the processing tank by energizing the heater core wire is often used. As shown in FIG. 11, two thermistors, a thermistor 7 that is disposed on the heater core 6 and detects the temperature of the heater core 6 and an outside air temperature detection thermistor (not shown) that detects the outside air temperature, are used. It is set as the structure which controls the electricity supply to a heater core wire based on the output of two thermistors.
[0004]
If it is this structure, when the outside temperature detection thermistor detects below predetermined temperature, electricity supply to the heater core wire 6 will be turned ON. After the energization, as shown in FIG. 12, when the temperature of the heater core 6 rises and reaches T2, the thermistor B detects the temperature and turns off the energization to the heater core 6. Thereafter, when the temperature of the heater core wire 6 drops and reaches T1, the thermistor 7 detects the temperature and turns on the power to the heater core wire 6. If the outside air temperature does not exceed the predetermined temperature, the heater ON / OFF control as described above is repeated.
[0005]
However, since the thermistor 7 is disposed on the heater core wire 6 and the thermistor 7 detects only the temperature of the heater core wire 6, the ratio between the ON time and the OFF time of the heater ON / OFF control is related to the outside air temperature. The amount of heat supplied to the carrier in the treatment tank is constant.
[0006]
Therefore, in winter when the outside air temperature is low, the amount of heat supplied from the heater is insufficient due to the influence of the ambient temperature, and the temperature of the carrier in the treatment tank is lowered, so that the activity of microorganisms is lowered and the organic matter treatment efficiency is deteriorated. There is.
[0007]
In addition, in the spring and autumn when the outside air temperature is slightly lower than the predetermined temperature that is a reference for determining energization to the heater, the temperature of the carrier in the processing tank becomes too high due to the amount of heat supplied excessively from the heater. There are drawbacks in that the activity of microorganisms decreases, the organic matter processing efficiency deteriorates, and the electricity cost of the heater is wasted.

The exhaust port 15 formed in the lower case 10 communicates with the exhaust passage 15 formed on the rear surface of the processing tank 1.
[0020]
Reference numeral 17 denotes a substrate storage case that covers the upper portion of the recess 12 in a state where a space is formed between the bottom surface of the recess 12 and is screwed to the recess 12. The planar heater 4, a fan 19 and an electric motor 21 described later.

It constitutes a circulation path that circulates.
[0021]
Reference numeral 19 denotes a fan mounted on the discharge cylinder 14. When the fan 19 is driven, the air in the processing tank 1 is sucked from the suction cylinder 13 and is discharged through the space between the recess 12 and the substrate storage case 17. Although it is discharged from the cylinder 14, the discharge cylinder 14 is divided forward and backward by the rear wall of the processing tank 1, so that air sucked from the intake cylinder 13 circulates in the processing tank 1 through the circulation path, A part of this air is exhausted from the exhaust port 16 to the outside through the exhaust passage 15 from the rear portion of the discharge cylinder 14.
[0022]
Reference numeral 20 denotes a recess formed in the upper part of the processing tank 1 adjacent to the suction cylinder 13, and an electric motor 21 is provided. The electric motor 21 is configured to decelerate the rotation of the electric motor 21 by a speed reduction mechanism 22 and to rotationally drive a stirring body 23 described later.
[0023]

[0025]
Reference numeral 28 denotes a charging opening formed on the upper surface of the upper case 27, and an opening edge extends into the processing tank 1. A lid 29 is swingably supported on the upper surface of the upper case 27 and closes the closing opening 28 so as to be freely opened and closed.
[0026]
Thus, the lid 29 is opened, and the soot is poured into the treatment tank 1 from the loading opening 28, and the lid 29 is closed. Detection means (not shown) detects the closure of the lid 29, and the control circuit energizes the motor 21, the planar heater 4 and the fan 19 based on the output.
[0027]
The energization of the electric motor 21 and the planar heater 4 rotates the agitator 23 to mix the carrier 2 and the soot, and maintain the temperature in the treatment tank 1 within the optimum range for the activation of aerobic microorganisms and the like. The straw is decomposed into carbon dioxide and water by aerobic microorganisms cultured on the carrier 2 and composted.
[0028]
In addition, when the fan 19 is energized, the air in the treatment tank 1 is circulated through the circulation path to vaporize moisture generated by decomposition of the soot , and the water content of the carrier 2 is an optimum range for activating the aerobic microorganisms. And supplying oxygen necessary for the activation of aerobic microorganisms.
[0029]
A part of the air circulating in the processing tank 1 is exhausted from the rear part of the discharge tube 14 to the outside of the main body case through the exhaust path 15 and the exhaust port 16, and the air in the processing tank 1 becomes overhumid. In addition to improving the water removal efficiency in the treatment tank 1, the aerobic microorganisms are activated, and the soot treatment capacity is improved.
[0030]
As the air in the processing tank 1 is exhausted to the outside, outside air is taken into the main body case from the air inlet 11 formed in the lower case 10, and the suction port 9 formed on the side surface of the processing tank 1 and the upper part of the processing tank 1. Although supplied into the processing tank 1 from a plurality of notches 3 provided in the opening, the air taken into the main body case is heated by the planar heater 4 and mixed with the air circulating in the processing tank 1. Therefore, even when the outside air temperature is low, such as in winter, the temperature in the treatment tank 1 is not greatly reduced.
[0031]
Moreover, since the air supply to the processing tank 1 is performed from the suction port 9 and the plurality of notches 3, the air speed of the supplied air is reduced, and the air is dispersed from the entire circumference of the processing tank 1 to take in the air. As a result, the supplied air is concentrated in one place, and the drying of the surface of the carrier 2 caused by increasing the wind speed and contacting a part of the carrier 2 can be prevented.
[0032]
The relationship between the outside air temperature and the control of the planar heater 4 according to the configuration of the present invention is as shown in FIGS.
[0033]
Since the thermistor 7 is mounted facing the air flow path and separated from the heater core wire 6 by a predetermined distance, the temperature of the heater core wire 6 is detected only when the temperature near the heater core wire 6 rises.
[0034]
When the thermistor 7 detects a temperature equal to or lower than the predetermined temperature T1, the control unit turns on the energization to the heater core wire 6, and when the thermistor 7 detects the predetermined temperature T2 higher than the predetermined temperature T1, the control unit energizes the heater core wire 6. Set to OFF.
[0035]
When the outside air temperature is low, such as in winter, the temperature rise rate in the vicinity of the heater core 6 becomes slow due to the influence of the cold outside air passing through the air flow path, and it takes time for the thermistor 7 to detect the predetermined temperature T2. The ON time becomes longer. When the heater core 6 is turned off, the vicinity of the heater core 6 is cooled by the outside air, and the thermistor 7 detects the predetermined temperature T1 in a short time, so the OFF time is shortened (see FIG. 8).
[0036]
Accordingly, since the amount of heat supplied from the planar heater 4 to the carrier 2 in the treatment tank 1 is increased, the temperature of the carrier 2 in the treatment tank 1 is set to an optimum temperature for activating microorganisms without being affected by a decrease in ambient temperature. Can be maintained. Moreover, since the cold external air supplied in the processing tank 1 is heated extra by the planar heater 4 which increased the amount of heat, the temperature fall in the processing tank 1 can be suppressed.
[0037]
On the other hand, when the temperature is relatively warm such as in spring or autumn, the temperature rise rate near the heater core wire 6 is increased due to the influence of warm outside air passing through the air flow path, and the thermistor 7 detects the predetermined temperature T2 in a short time. ON time is shortened. When the power to the heater core 6 is turned off, the vicinity of the heater core 6 becomes difficult to be cooled by warm outside air, and the thermistor 7 takes time to detect the predetermined temperature T1, so the OFF time becomes long (see FIG. 9). ).
[0038]
Therefore, the amount of heat supplied from the planar heater 4 to the carrier 2 in the treatment tank 1 can be reduced, and the temperature of the carrier 2 in the treatment tank 1 can be maintained at an optimum temperature for activating microorganisms. Furthermore, since the OFF time of the planar heater 4 becomes long, the electricity bill can be saved.
[0039]
Further, since the thermistor 7 is mounted on the outer wall of the treatment tank 1, the planar heater 4 can be controlled by changing the moisture content of the carrier 2.
[0040]
That is, as shown in FIG. 7, when the moisture content of the carrier 2 is 80%, the water is excessive and the treatment state is deteriorated. At this time, the temperature of the carrier 2, along with moisture is excessive, since the amount of heat even less with generated degradation of kitchen waste, lower than when the good water content of 60% of the processing state of the garbage, the thermistor 7 is treating tank 1 It is cooled by the carrier 2 via Therefore, the ON / OFF control of the planar heater 4 increases the ON time as shown in FIG. 8 and increases the amount of heat supplied from the planar heater 4 to the carrier 2 in the treatment tank 1, so that the moisture of the carrier 2 is positively increased. The water content of the carrier 2 can be lowered by evaporating the water.
[0041]
Conversely, when the moisture content of the carrier 2 is 40%, it is dry, so the temperature of the carrier 2 is higher than when the moisture content is 60%, and the thermistor 7 is heated by the carrier 2 via the treatment tank 1. . Accordingly, the ON / OFF control of the planar heater 4 increases the OFF time as shown in FIG. 9 and reduces the amount of heat supplied from the planar heater 4 to the carrier 2 in the treatment tank 1. Can be suppressed, and the water content of the carrier 2 can be increased.
[0042]
In the present embodiment, the thermistor 7 is mounted 27 mm away from the heater core wire 6 on the outer periphery of the planar heater 4, but the distance between the thermistor 7 and the heater core wire 6 is the mounting position relative to the planar heater 4 and the planar shape. It is set according to conditions such as the capacity of the heater 4, the air volume of the fan 19, the material and thickness of the processing tank 1, and is not limited to this embodiment. Moreover, the planar heater 4 is not limited to this Embodiment, The structure which arrange | positioned only the heater core wire 6 to the processing tank 1 outer wall may be sufficient.
[0043]
FIG. 10 shows another embodiment, in which the thermistor 7 is not on the base 5 of the planar heater 4 but on the air flow path, and is separated from the heater core 6 by a predetermined distance, and the lower part of the outer wall of the processing tank 1. It has a configuration attached to. Even with this configuration, the same operational effects as the above-described embodiment can be obtained.
[0044]
【The invention's effect】

According to the configuration of the second aspect of the present invention, since the inside of the treatment tank is maintained at the optimum temperature for the activity of the microorganisms regardless of the outside air temperature by one temperature detection unit, an effect such as being able to perform stable soot treatment at all times, etc. Play.

According to the configuration of claim 3 of the present invention, the temperature inside the treatment tank is maintained at an optimum temperature for the activity of microorganisms regardless of the outside air temperature by one temperature detection unit, and the moisture content of the carrier is adjusted to an optimum state. Therefore, there is an effect that a stable wrinkle treatment can be performed at all times.
