BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating organic matter, and more particularly, to an organic matter for decomposing organic matter such as kitchen garbage (garbage) by microorganisms cultured on a carrier made of wood chips or the like. The present invention relates to a processing device.

2. Description of the Related Art Conventionally, this type of organic substance processing apparatus includes a processing tank for accommodating an organic substance to be treated together with a carrier, and a processing tank disposed at a predetermined location for heating the organic substance and the carrier in the processing tank. A heater, an exhaust fan for discharging air in the processing tank, and a stirring body that is rotatably disposed in the processing tank and stirs organic substances and carriers in the tank,
A motor having a motor for rotationally driving the stirring body is known.

In such an organic substance processing apparatus, the temperature of the processing tank is different between a place where the organic substance and the carrier are present (heated by a heater) and a place where these are not present. Due to the fact that the location is higher, a plurality of temperature sensors are attached to the outer surface of the processing tank with a difference in height, and the temperature of a predetermined location is measured with these temperature sensors, and based on the measurement result, The bulk of the organic substance and the carrier inside the processing tank is estimated.

For example, a first temperature sensor is provided at a low position of a processing tank corresponding to a lower limit level of a carrier accommodated in a processing tank, a second temperature sensor is provided at an intermediate position corresponding to an appropriate level of the carrier, and an upper limit level of the carrier is provided. The third temperature sensor is located at a higher position corresponding to the temperature, and the fourth temperature sensor is located at a higher position which is not affected by the temperature of the carrier.
Each temperature sensor (reference temperature sensor) is attached.

[0005] The control unit compares the difference between the temperature measured by each of the first to third temperature sensors and the temperature measured by the reference temperature sensor with a predetermined value, and determines whether the bulk of the organic substance and the carrier is lower than each level. Is also determined to be above or below.

Next, the control unit performs control for displaying the bulk and adjusting the heating condition by the heater.

[0007]

However, in such an organic substance processing apparatus, since a plurality of temperature sensors are provided, not only is the control of the apparatus complicated but also disadvantageous in terms of cost. was there.

The present invention has been made in view of such circumstances, and a main problem thereof is to provide an organic substance processing apparatus in which the control of the apparatus by a temperature sensor is simple and the cost is advantageous. It is in.

[0009]

According to one aspect of the present invention, there is provided a processing tank for containing an organic substance to be processed together with a carrier, a heater for heating the organic substance and the carrier in the processing tank, An exhaust fan for exhausting air from the processing tank, a stirring body rotatably disposed in the processing tank, and for periodically stirring the organic matter and the carrier in the processing tank; and a rotational drive of the stirring body. And a motor for performing
At least one temperature sensor attached to the processing tank for detecting a temperature change in the processing tank before and after the stirring operation by the stirrer, and the volume of the organic matter and the carrier in the processing tank based on the detection result of the temperature sensor. And a control unit for controlling at least one of the heater, the exhaust fan, and the motor in accordance with the estimation result.

The treatment tank accommodates organic matter such as kitchen waste to be treated, together with a carrier for microorganisms for decomposing organic matter, and comprises, for example, two sets of opposed side walls and one bottom wall. Has an input port. Here, as the carrier, for example, a mixture of woody fragments such as sawdust and activated carbon is preferably used. A lid is attached to the processing tank so as to open and close the inlet, and the lid turns on / off the power supply of the apparatus in conjunction with the opening / closing operation.
It is preferable that it is comprised so that it may perform.

As the heater, for example, a planar heater or a linear heater mounted on the outer surface of the side wall of the processing tank is used. Organic matter in the processing tank heated by the heater is mainly decomposed into water and carbon dioxide by activating microorganisms (particularly aerobic microorganisms) held on the carrier. The exhaust fan discharges moisture and carbon dioxide in the processing tank by discharging air in the processing tank to the outside of the processing tank through an exhaust port and an exhaust passage, thereby promoting the decomposition of organic substances by microorganisms.

[0012] The agitator comprises, for example, a stirring shaft disposed so as to penetrate a pair of opposing side walls of the processing tank, and a plurality of stirring blades provided on the stirring shaft. In this case, the stirring shaft is rotated periodically (for example, 30 to 6).
The stirring blade stirs the organic matter in the tank together with the carrier along with the rotation (1 to 2 times every 0 minutes, rotation for several minutes each time). This agitation promotes the decomposition of organic substances by microorganisms.

The rotation speed and the mode of rotation of the stirrer (forward rotation,
The reversal and stop) are appropriately set depending on the size of the processing tank, the amount of organic substances and carriers contained in the processing tank, and the like. The stirrer is rotationally driven by a drive motor via, for example, a gear or a rotating disk.

The organic matter treating apparatus according to the present invention further comprises:
It has one temperature sensor and a control unit as described below.

The temperature sensor is attached to the outer surface of the processing tank, and detects a temperature change of the processing tank before and after the stirring operation by the stirring body. That is, when the organic matter and the carrier in the processing tank are sufficiently stirred, the temperature of the processing tank is reduced as compared to before the stirring, and the temperature sensor detects the start of one time of stirring with the stirrer that is periodically performed. The temperature change of the processing tank is detected by measuring the temperature of the outer surface of the processing tank before and the temperature after the end of the stirring.

The controller estimates the bulk of the organic substance and the carrier in the processing tank based on the detection result of the temperature sensor. For example, assuming that a temperature sensor is mounted on the outer surface of the processing tank corresponding to the upper limit level of the processing tank for storing one temperature sensor-the upper limit position for storing the organic matter and the carrier-before and after stirring by the temperature sensor. If no temperature change is detected, it is presumed that organic substances and carriers are not contained up to that level, and if a temperature change (temperature drop) is detected, it is presumed that organic substances and carriers are contained near that level. I do.

Then, the control unit controls at least one of the heater, the exhaust fan, and the motor according to the estimation result to create an appropriate operation mode of the present apparatus. Thereby, appropriate organic substance processing can be performed according to the bulk of the organic substance and the carrier in the processing tank.

In the organic matter treating apparatus according to the present invention, more preferably, the treatment tank comprises two sets of opposed side walls and one bottom wall, and the stirrer penetrates the set of opposed side walls of the treatment tank. A temperature sensor was attached to a location corresponding to the upper limit level of the carrier on the outer surface of one of the other pair of opposing side walls, which was provided with a stirring shaft provided and a plurality of stirring blades provided on the stirring shaft. A thermistor for measuring temperature, wherein the control unit is configured to increase or decrease at least one of a heating temperature and a heating time of a heater, a rotation speed and an operation time of an exhaust fan, and a rotation speed and a driving time of a motor. You.

Here, the temperature sensor is attached to one outer surface of another set of opposed side walls (for example, one set of opposed side walls substantially parallel to the stirring shaft) because the stirring shaft penetrates. This is because the temperature change of the temperature sensor due to the stirring can be made larger than that in the case where the temperature sensor is attached to one of the outer surfaces of the pair of opposed side walls, so that more accurate control can be performed. is there.

According to another aspect of the present invention, there is provided a processing tank for accommodating an organic substance to be processed together with a carrier, and a surface mounted on an outer surface of the processing tank for heating the organic substance and the carrier in the processing tank. A heater, an exhaust fan for discharging air in the processing tank, a stirrer disposed rotatably in the processing tank, and for periodically stirring the organic matter and the carrier in the tank; A motor for rotationally driving the heater, and further attached to the planar heater to prevent an abnormal rise in temperature of the heater and to detect a temperature change in the processing tank before and after the stirring operation by the stirring body. At least one temperature sensor and the bulk of the organic matter and the carrier in the processing tank are estimated based on the detection result of the temperature sensor, and at least one of the heater, the exhaust fan, and the motor is determined according to the estimation result. Organic matter processing apparatus is provided which is characterized by comprising a control unit for controlling the One.

The reason why the planar heater is used is to make the temperature distribution in the processing tank as uniform as possible. This planar heater includes, for example, a lower heater for heating the bottom of the processing tank and an upper heater for heating the upper part of the processing tank.

One temperature sensor is attached to the planar heater to prevent abnormal temperature rise of the heater (preventing abnormal temperature rise) and detect a temperature change of the processing tank before and after the stirring operation by the stirring body. (Temperature measurement). That is, this temperature sensor is normally turned on / off by a control thermistor attached to the lower heater, for example.
It is controlled and operates when the temperature of the upper heater becomes abnormally high to stop heating by the upper heater. As described above, since one temperature sensor performs two functions, this measure is simple in control and advantageous in cost.

The control unit estimates the bulk of the organic matter and the carrier in the processing tank based on the detection result of the temperature sensor, and controls at least one of the heater, the exhaust fan, and the motor according to the estimation result. To create an appropriate operating mode of the device. Thereby, appropriate organic substance processing can be performed according to the bulk of the organic substance and the carrier in the processing tank.

[0024] In the organic matter treating apparatus according to the present invention, more preferably, the treatment tank comprises two sets of opposed side walls and one bottom wall, and the agitator penetrates the set of opposed side walls of the treatment tank. The stirring shaft is provided with a plurality of stirring blades provided on the stirring shaft, and the heater includes a lower heater for heating the bottom of the processing tank and an upper heater for heating the upper part of the processing tank. The temperature sensor is an abnormal temperature rise prevention and temperature measurement thermistor attached to the upper heater, and the control unit controls the heating temperature and heating time of each heater, the rotation speed and operation time of the exhaust fan, and the motor It is configured to control increase or decrease of at least one of the rotation speed and the drive time.
