Reference numeral 75 is a motor rotation sensor, and the rotation speed of the stirring claw drive motor 50 is detected by the motor rotation sensor 75.

In this way, in the garbage processing section 2, as shown in FIG. 6, after the garbage is put into the fermentation treatment tank 32, it is attached to the stirring claw support shaft 40 by the stirring claw driving motor 50. By rotating the stirring claws 41, 42, 43, 44 counterclockwise in a side view, it is possible to perform the fermentation treatment while stirring the garbage.

At this time, when the garbage is introduced for the first time, an auxiliary material (for example, an aerobic bacterium adhered as an inoculum) (for example,
Sawdust, Zeolite, Perlite) is added together with raw garbage to promote fermentation of the raw garbage and prevent crushed and stirred raw garbage from being ground and liquefied so that it becomes as porous as possible. To do. And
After that, the fermented material that is partially retained in the fermenter tank 32 acts as a substitute for sub-materials to perform the fermentation promoting function, and the garbage is treated for a certain period, for example, for one month.
It is retained in 32 and fermented and then aged to be collected as the final residue.

As shown in FIG. 7, the fermented product that has undergone the fermenting process has its stirring claws 41, 42, 43, 44 rotated clockwise in a side view by a stirring driving motor 50. Thus, the fermented product B scraped up by the second stirring claw 42 can be overflowed into the aging treatment tank 33 through the first overflow window 34.

At this time, the tip blades 44a, 44b of the fourth stirring claw 44 arranged in the aging treatment tank 33 are the tip blades of the second stirring claw 42.
The fermentation treatment product B scraped up by the second stirring claw 42 overflows into the aging treatment tank 33 through the first overflow window 34 because the fermentation treatment product B is advanced by the phase angle θ in the forward rotation direction relative to 42a, 42b. In doing so, one tip claw of the fourth stirring claw 44 closes most of the first overflow window 34 in a side view, and the first overflow window 34 and the second overflow window 34
It is possible to prevent a short path in which the fermented material B that overflows is directly recovered by the recovery unit 3 through the second overflow window 35 by providing a certain height difference H with the overflow window 35. I have to.

The fermented product transferred into the aging treatment tank 33 can be further fermented and aged while being stirred by the fourth stirring claw 44. Therefore, a fibrous plant that is hardly fermented in the aging treatment tank 33 can be surely fermented and aged.

At this time, in the aging treatment tank 33, the aging treatment product is transferred to the second overflow window by the fourth stirring claw 44 which rotates forward.
It is made possible to overflow into the recovery section 3 through 35.

Here, when the above-mentioned fermentation treatment and aging treatment are performed, the raw garbage treatment tank 30 is heated by the planar heater 37 stretched over the arc-shaped bottom portion 30e of the raw garbage treatment tank 30. In the lower part of the left side wall 30a of the raw garbage treatment tank 30, a temperature sensor 76 and a humidity sensor 77 are installed in the fermentation treatment tank.
Mounted so as to project inside 32, connect both sensors 76 and 77 to a control unit 80 described later, and control the temperature of the heater 37 by the control unit 80 so that fermentation / aging treatment can be performed at a desired temperature. I have to.

Collection gutter 60 placed in the space formed between 30b and
And a recovery tray 61 arranged directly below the lower end portion 60b of the recovery gutter 60.

As shown in FIGS. 3 to 5, the collecting trough 60 is attached by connecting the upper end portion 60a to the second overflow window 35 formed on the right side wall 30b of the garbage disposal tank 30 and connecting the same to the right side. The lower end portion 60b is extended downward inward along the wall 30b from the position of the arc-shaped bottom portion 30e of the raw garbage processing tank 30 so as to protrude downward leftward. Reference numeral 78 is a discharge sensor, and the discharge sensor 78 detects the discharge timing when the final residue accommodated in the recovery tray 61 is fully distributed.

As shown in FIGS. 3 to 5, the recovery tray 61 is formed in the shape of a horizontally long rectangular box extending in the front-rear direction, and is located directly below the lower end portion 60b of the recovery gutter 60.
It is placed on the floor 10d of 10.

In this way, the aged processed material aged in the aged processing tank 33 of the raw garbage processing tank 30 overflows into the recovery gutter 60 through the second overflow window 35, and passes through the recovery gutter 60 to a recovery tray. It is being collected within 61.

The recovery tray 61 is provided with a discharge lid 14
The handle 21 is operated to open it so that it can be easily taken out.

As shown in FIGS. 3 to 5, the deodorizing unit 4 has a deodorizer 65 disposed adjacent to the recovery tray 61 on the floor 10d of the casing body 10, and the deodorizer 65 has an exhaust fan.

A horizontally long suction window 71 is formed in the upper and lower parts in the left-right width direction, and a net body 72 is stretched over the suction window 71.

Here, the deodorizer 65 contains therein rock wool which has been fired from rock and processed into a cotton shape. The rock wool is propagated by aerobic microorganisms which decompose odorous components, and rock wool is produced. The malodorous components in the exhaust gas are adsorbed on, and the malodorous components are decomposed by aerobic microorganisms to release the deodorized exhaust gas.

Further, an exhaust hole (not shown) is formed in the lower portion of the deodorizer 65, and an exhaust hole 10e is formed in the floor portion 10d of the casing body 10 so that the exhaust hole 10e is vertically aligned.
An exhaust guide body 73 is attached to guide the exhaust gas to the rear along the lower surface of the floor 10d.

In this way, in the deodorizing section 4, by operating the exhaust fan, the exhaust gas in the garbage processing tank 30 is exhausted from the tank exhaust passage 36 → exhaust window 69 → exhaust case 68 → exhaust duct 67 → The air is sucked into the exhaust fan case 66 and sent under pressure into the deodorizer 65 to deodorize in the deodorizer 65, and then the deodorizer.
Exhaust hole 10e of 65 → Exhaust hole of floor 10d of casing body 10

At this time, when the current of the power source is 60 Hz, the rotation speed of the stirring claw drive motor 50 can be set to, for example, 4.0 rpm, and when it is 50 Hz, the rotation speed of the motor 50. Can be set to, for example, 3.5 rpm.

[Stirring operation control] In the stirring operation, as shown in FIG. 9, each stirring claw 41, 42, 43, 44 is rotated in the reverse direction for 6 minutes before the lapse of 1 hour after the above-described crushing operation is completed. The operation is repeated 5 times continuously, and then the operation of rotating the stirring claws 41, 42, 43, 44 forward for 6 minutes before 1 hour is continuously repeated until the closing lid 12 is opened. Is.

When the charging lid 12 is opened during the stirring operation, the timer is reset as shown in FIG. 10, and the crushing operation is executed from the beginning.

Therefore, each of the stirring claws 41, 42, 43, 44 again rotates in the normal direction again 7 hours after the closing of the charging lid 12.

In this way, with 24 hours as one cycle, the stirring claws 41, 42, 43, 44 are set to rotate in the normal direction during one cycle, and the fermentation treatment tank 32 → the aging treatment tank 33 is set.
Fermentation products are overflowed through the first overflow window 34, and at the same time, the agitation / overflow operation is performed in which the aged treatment product is overflowed to the maturation treatment tank 33 → the recovery gutter 60 through the second overflow window 35. By not increasing the amount of the processed material in 32,33 beyond a predetermined amount, the fermentation and aging process can be properly performed in each processing tank 32,33.

[Temperature Control] The temperature control is to control the temperature in the raw refuse processing tank 30 heated by the heater 37 based on the detection result of the temperature sensor 76.

The discharge control over time is shown in FIG.
As shown in (b), when the power is first turned on, the closing lid 12 is once opened from the closed state, and the discharge display lamp 85 blinks three weeks after it is closed again.

The blinking of the discharge indicator lamp 85 is canceled when the discharge lid opening / closing detection switch 16 detects that the discharge lid 14 is once opened from the closed state and is closed again while the lamp is blinking. ing.

After that, 1 after the discharge lid 14 is closed.
The discharge indicator lamp 85 blinks after a lapse of a week.

Further, when the discharge lid 14 is once opened from the closed state, the driving of the stirring claw driving motor 50 and the exhaust fan driving motor 81 is stopped, and when the discharge lid 14 is closed again. As shown in FIG. 10, the control which is performed when the discharge lid 14 is opened is continuously performed. However, the temperature control is to maintain the state immediately before the discharge lid 14 is opened.

[Drying Operation Control] The drying operation is performed when the water content of the fermented product detected by the humidity sensor 77 is 50% or more at the time when the above-mentioned fermentation process is completed.
The drying mode display lamp 84 is turned on, the temperature control is maintained at 65 ° C. which is the high temperature for drying, the stirring claws 41, 42, 43, 44 are reversely rotated for 20 minutes and then stopped for 20 minutes. The operation is repeated for 12 hours, and after the lapse of 12 hours, the drying mode display lamp 84 is turned off.

Further, the drying operation can be forcedly performed by the user by judging the trouble of the fermentation state.
As shown in 2, dry switch 79 is turned on continuously for 5 seconds.
Then, the drying operation is started.

When the drying operation is not performed, the state in which the crushing operation control or the stirring operation control is performed is restarted.

Here, the moisture content of the treated material detected by the humidity sensor 77 is 30% to 40% or less, preferably 35%.
When it reaches%, the drying operation is stopped immediately.

In this way, the running cost of the heater 37 is reduced and the electric power can be effectively used.

[Exhaust Operation Control] In the exhaust operation, when the closing lid opening / closing detection switch 15 or the discharging lid opening / closing switch 16 detects that the closing lid 12 or the discharging lid 14 is changed from the closed state to the open state, the stirring claw driving is performed. The motor 50 and the discharge fan driving motor 81 are immediately stopped, and when the closing lid opening / closing detection switch 15 or the discharging lid opening / closing detection switch 16 detects that the closing lid 12 or the discharging lid 14 is changed from the open state to the closed state. ,
This is an operation in which both the motors 50, 81 are immediately and continuously driven.

[Motor Overload Control] In the motor overload control, as shown in FIG. 13, 1 second after the drive of the stirring claw drive motor 50 is started, the motor rotation sensor 75 outputs a pulse every 500 ms. When the number of rotations of the motor 50 becomes less than 800 rpm after counting, it is judged that the motor 50 is overloaded, the motor 50 is stopped for 5 seconds, and then the motor 50 is rotated before the stop. In this control, the motor is rotated in the reverse direction for 20 seconds, then stopped for 5 seconds, and then the operation before the overload is applied is continued.

Then, such an operation is repeated up to three times, and when the overload is still applied, the stirring claw driving motor 50 is stopped and the motor overload display lamp 83 blinks. However, the heater 37 maintains the state before the motor overload control.

The maintenance state is maintained until the power is turned off, and when the power is turned on again, the state before the motor overload control is resumed. There is.

In the above description of control, specific numerical values are described for time, temperature, number of times, etc.
These are merely specific examples of preferable numerical values, and are not limited to these numerical values.

[0083]

According to the present invention, the following effects can be obtained.

In the present invention according to claim 1, raw garbage can be fermented by stirring the stirring claw provided in the fermentation treatment tank in the reverse rotation direction, and the fermented product is the stirring claw. By carrying out the stirring operation in the normal rotation direction, it is possible to scrape up to the first overflow window and overflow and transfer into the aging treatment tank.

By performing stirring operation in the reverse rotation direction of the stirring claws in the aging treatment tank, it is possible to further ferment a processed product that is difficult to ferment to complete aging treatment. By carrying out the stirring operation in the forward rotation direction, it is possible to scrape up to the second overflow window and overflow and transfer it to the recovery section.

At this time, the recovery section is connected to the aging treatment tank through a second overflow window which is located at a position lower than the first overflow window. While the stirring claw capable of stirring operation is provided, the first and second overflow windows are respectively provided only at the positions where the fermented material is scraped up during the stirring operation in the normal rotation direction of the stirring claw, and the processing object is provided by the stirring claw. To overflow through each overflow window,
The processed product can be continuously and reliably transferred from the fermentation treatment tank to the aging treatment tank to the recovery section, and further, with some of the treated material remaining in each treatment tank, it is possible to continuously transfer the raw garbage. fermentation·
While performing the aging treatment, the final residue subjected to the aging treatment can be regularly collected from the collection unit.

According to the second aspect of the present invention, when the stirring claws in the fermentation treatment tank scrape up the fermented material up to the first overflow window, most of the first overflow window is in the aging treatment tank. Since the stirring claws are blocked, it is possible to prevent a short path in which the fermented product is directly collected through the second overflow window to the collection section, and the fermented product is aged in the aging tank surely. After processing, it can be recovered as a final residue from the recovery unit.
