The shower 40 includes a pipe 43 and a solenoid valve 4.
4 is connected to the pump 23 in the tank 31 via 4, and if necessary, an appropriate amount of water is sprayed to the decomposition tank 16 to supply the water necessary for the activity of the microorganism 39. The stirring unit 41 is
As shown in FIG. 2, a plurality of flat plates 46 are erected on the rotary shaft 45, and in this example, the adjacent flat plates 46 are arranged at positions separated by 90 degrees. A rotating shaft 45 of the stirring unit 41 is rotatably attached to the side walls 47 of the decomposition tank 16, and is rotationally driven by a motor 48. As a result, the microorganisms 39, sawdust and air are mixed and stirred, and the activity of the microorganisms 39 is promoted. In this example, two stirring units 41 are arranged in parallel in the decomposition tank 16.

The heater 42 has a flat plate shape and is attached to the surface of the flat plate 46 of the stirring section 41. Since the flat plate 46 always enters the fungal bed as the rotary shaft 45 rotates, the heater 42 also necessarily enters the fungal bed. Therefore, by setting the heater 42 at a predetermined temperature, the fungal bed is entirely heated to an appropriate temperature, and the decomposition activity of the microorganism 39 becomes active.

A relatively thick pipe 49 communicating with the outside is provided in the upper portion of the decomposition tank 16 to replenish the microorganisms 39, and a solenoid valve 50 is attached to the lower end portion thereof. An open / close lid 51 is provided at the upper end of the pipe 49. The pipe 49 and the electromagnetic valve 50 constitute a microorganism replenishing means. Inside the pipe 49, powdered microorganisms 39
Is clogged. Since the pipe 49 leads to the outside,
From here, the user can appropriately add the powder of the microorganism 39 at any time.

The decomposing tank 16 is provided with dust 12 in the decomposing tank 16.
A detection 53, which is a state change detection means for detecting the amount of state change that occurs when is decomposed, is provided. In this example, the detection unit 53 detects the fermentation heat generated when the microorganisms 39 decompose the garbage 12, that is, the temperature change in the decomposition tank 16, and supplies the detected value to the control unit 54. It is generally known that the more active the decomposition activity of the microorganism 39, the more heat of fermentation is generated. From this,
When the temperature in the decomposition tank 16, that is, the fermentation heat becomes less than or equal to a predetermined value, it can be determined that the decomposition tank 16 is deficient in the microorganisms 39.

Below the decomposition tank 16, dust 12 in the apparatus is placed.
A weight sensor 55, which is a weight detecting means for detecting the weight of the, is arranged. The output of the weight sensor 55 is sent to the control unit 54, and the weight of the entire device including the dust 12 detected by the weight sensor 55, including the dust 12, is measured in advance.
The weight of the dust 12 is calculated by subtracting the weight of the device including 4.

The control unit 54 determines the replenishment timing of the microorganisms 39 based on the temperature inside the decomposition tank 16 measured by the detection unit 53 and the weight of the dust 12 detected by the weight sensor 55. That is, the control unit 54 acts as a state change calculation means for calculating the fermentation heat to be generated by the weight of the thrown-in waste 12, and the fermentation heat calculated here and the fermentation heat actually detected are calculated. Acts as a comparison means for comparison. Then, when the detected value is smaller than the calculated value, it is determined that the microorganism 39 is insufficient, and the electromagnetic valve 50 of the pipe 49 is opened for a predetermined period of time to cause the microorganism 39.
Is replenished by a predetermined amount.

Here, since the supplemental amount of the microorganisms 39 is determined from the ratio of the calculated value and the detected value, the appropriate amount of the microorganisms 3 is always maintained.
9 will be retained in the decomposition tank 16. Control unit 54
Then, each solenoid valve 44, 52, 50, motor 27, 36,
48 and the pump 23 are controlled.

Next, the operation of the dust processing apparatus 1 will be described.
When processing the dust 12, as shown in FIG.
Is opened and the dust 12 is thrown into the dust throwing section 13.
The thrown dust 12 slides down the funnel portion 19 of the dust throwing portion 13, is cut by the blade 25 of the rotating cutter 14, and is crushed. At this time, since the blade 25 is horizontally long, the slender dust 12 and the thin and large dust 12 are surely crushed.

The crushed dust 12 falls on the mesh portion 33 of the water separating portion 15 through the passage hole 29 of the sieve portion 28 and the dust dropping portion 20. Then, here, the water 34 contained in the dust 12 is separated and stored in the tank 31, and the dust 12 is splashed by the mesh portion 33 and stored in the decomposition tank 16.

In the decomposition tank 16, the dust 12 is stirred by the stirring section 41 and decomposed into carbon dioxide gas, water and the like by the microorganisms 39. At this time, as described above, the activity of the microorganisms 39 is promoted by the temperature adjustment by the heater 42 and the water sprayed from the shower 40, and the debris 12 is decomposed efficiently.

The temperature of the decomposition tank 16 at the time of disassembling the dust 12 is detected by the detection unit 53, and the weight of the dust 12 is detected by the weight sensor 53. Based on this, the control unit 54
The timing of supplementation of the microorganism 39 is determined. Then, the electromagnetic valve 50 of the pipe 49 is opened / closed, so that the microorganism 39 decomposes the microorganism 39.

FIG. 3 is a flow chart showing the procedure of the replenishing process 60 of the microorganism 39. In this replenishment process 60,
First, the current weight of the entire apparatus is detected by the weight sensor 55 (step 61), and then it is determined whether or not the dust 12 has increased (step 62). When the amount of waste 12 increases, the decomposition tank 1 that should be generated by the increased amount of waste 12
An appropriate temperature of the fermentation heat of No. 6 is calculated (step 63), and then it is determined whether the temperature of the decomposition tank 16 detected by the detection unit 53 is equal to or lower than the appropriate temperature (step 64). When the temperature is lower than the proper temperature, the electromagnetic valve 50 is opened for a predetermined time to replenish the microorganisms 39 in the pipe 49 into the decomposition tank 16 (step 65), thereby completing the replenishment process 60.

In this way, the microorganisms 39 are automatically replenished by detecting the temperature change in the decomposition tank 16 due to the heat of fermentation of the microorganisms 39 and the increased amount of the dust 12,
You can save time. In addition, the amount of the microorganisms 39 in the decomposition tank 16 can be always maintained in an appropriate amount, and the waste 12 can be decomposed in the optimum state.

As shown in FIG. 1, the dust processing apparatus 1 can clean the dust 12 adhering to the inside of the dust input unit 13. In this case, the pump 23 of the water separation unit 15 is driven, the cleaning water stored in the tank 31 is supplied to the nozzle 21 via the electromagnetic valve 52 and the pipe 22, and from there, the cleaning water is directed to the inner surface of the dust input unit 13. Is ejected. The washing water flows along the inner surface of the dust throwing portion 13 and drops on the mesh portion 33 together with the washed dust 12. Then, similarly to the above, the water content 34 is separated by the mesh portion 33 and stored in the tank 31. Further, the dust 12 is splashed by the mesh portion 33 and stored in the decomposition tank 16.

In the above-described embodiment, the stirrer 41 is described by arranging the flat plate 46 on the rotary shaft 45 and attaching the heater 42 to the flat plate 46. However, as shown in FIG. A plurality of dog-legged rotating portions 70 may be provided, and a stirring portion 72 may be formed by attaching heaters 71 on both sides of the rotating portion 70 as shown in FIG. The agitator 72 can be driven by a motor 73 as shown in the drawing, or can be simultaneously driven by a single motor by a gear device (not shown).

Further, in the above-mentioned embodiment, the detection unit 53 detects the temperature rise due to the heat of fermentation in the decomposition tank 16 to judge the degree of decomposition. The amount of dust 12 can be determined by detecting the amount.

This is because the microorganisms 39 generate carbon dioxide and steam in addition to the heat of fermentation when decomposing the refuse 12. This carbon dioxide and water vapor are also garbage 1 of the microorganism 39
It is generated according to the amount of decomposition of No. 2, and the degree of decomposition of the dust 12 can be determined by detecting the amount of decomposition. Therefore, the control unit 54 calculates the amount of carbon dioxide gas or water vapor that should be generated according to the weight of the input dust 12, and compares this with the actually detected carbon dioxide gas or water vapor to supplement the microorganisms 3.
The amount of 9 may be determined.

Further, if the amounts of the above-mentioned fermentation heat, carbon dioxide gas and water vapor are respectively detected and comprehensively judged, it is possible to more accurately determine the charging time and the charging amount.
