The figure is an electrical circuit diagram of the organic waste treatment apparatus of the present invention.

The overall configuration of the organic waste treatment apparatus will be explained with reference to FIGS. 1, 2, and 3.

The fermentation container 1 is configured to be divisible into upper and lower parts, and is composed of an upper fermentation container 1a and a lower fermentation container 1b.

The upper fermentation vessel 1a has a cross-sectional shape that becomes narrower as it goes upward, and the lower fermentation vessel 1b has a cross-sectional shape that becomes narrower as it goes downward.

By configuring the space to be narrower toward the top and narrower toward the bottom, the space can be narrowed along the rotation locus of the stirring claw 5, thereby eliminating wasted space.

Furthermore, both the upper fermentation vessel 1a and the lower fermentation vessel 1b are made of glass fiber reinforced resin (FRP), and when molding, the mold can be easily removed, resulting in lower manufacturing costs.

The upper and lower fermentation vessels 1a and 1b are connected at the central flange to form an integrated fermentation vessel 1.

A bearing is disposed in the lower fermentation vessel 1b, and a stirring claw shaft 2 is built thereon, and a plurality of stirring claws 5 are installed on the stirring claw shaft 2.

The number of stirring claws 5 is large in the lower part of the input port 33, then slightly less in the part of the partition plate 7 where fermentation has progressed, and in the part of the processed material discharge port 18 beyond the partition plate 7. Furthermore, the number of stirring claws 5 is reduced.

The stirring claw 5 is configured as a machete claw with a bent tip. Then, a cutting blade 3 is placed at the tip of the rotation locus of the stirring claw 5.
5 is arranged protrudingly, and the kitchen waste is crushed by the joint operation of the cutting blade 35 and the input port M3.

Further, an upper partition plate 6 and a middle partition plate 7 are installed in the fermentation container 1 so that the food waste input through the input port 33 and the fermented food waste to a certain extent are not mixed.

The space to the left of the upper partition plate 6 is a stirring chamber, and the space between the upper partition plate 6 and the middle partition plate 7 is a fermentation chamber.
The space to the left is configured as an extraction chamber.

In order to promote fermentation, pressurized air is blown from the blower 11, and after passing through the heater 8 and turning it into warm air,
The air is blown out from the air outlet 9 below the garbage.

Further, as the fermentation progresses, the fermented product that is pushed out by the garbage that is thrown in one after another and exceeds the partition plate 7 is discharged to the outside of the fermentation container 1 through the processed product discharge port 18.

A cooling case 4 is arranged outside the fermentation vessel 1, and a blower 11, a drive motor 10, and a speed reducer 12 are arranged inside the cooling case 4.

Further, an intake port 16 is opened on the front side of the upper fermentation container 1a, and intake ports 17 and 19 are opened on the side of the cooling case 4 of the upper fermentation container 1a.

Frames 21 are arranged on the lower surface of the lower fermentation container 1b to support the fermentation container 1.

Further, an input port 33, an inclined guide plate 34, an inspection opening cover 23, and an input port cover 3 are arranged on the upper surface of the upper fermentation container 1a.

The inspection opening lid 23 is opened for internal cleaning or inspection, and is normally kept closed.

In addition, the input port 3 is opened several times every day and serves as a port for inputting food waste. At the bottom of the fermentation container 1, frames 21 are installed.

The input port cover 3 is also provided with an opening/closing pedal 20 so that the operator does not have to grasp it to open/close it. When the operator steps on the opening/closing pedal 2o, the input port M3 is opened via the opening/closing link, and the input port M3 is opened and closed. When the opening lock lever 25 is rotated toward the lock side with the input port M3 in the open state, the opening lock lever 25 is configured to maintain the open/closed position.

When the opening/closing pedal 20 is depressed again after the food waste is thrown in, the locked state of the opening lock lever 25 is also released, and the feeding opening lid 3 is closed.

When feeding food waste through the input port 3, conventionally sawdust was also added as an auxiliary material, but this had the disadvantage that the final fermented product could not be reduced because it was difficult to ferment the sawdust. Therefore, in the present invention, compressed and solidified organic substances such as Ruthen pellets (grass pellets) and peat moss are used as auxiliary materials.

Because peat moss is solidified, it is easy to handle, and it no longer gets blown around by strong winds, as was the case with conventional sawdust. Furthermore, the peat moss exhibits effects such as absorption of moisture, promotion of fermentation, and supply of oxygen.

Furthermore, the exhaust fan 14 sucks in not only the gas generated inside the fermentation container 1 through the exhaust port 15 of the present invention, but also takes in external air from the intake port 16 and the intake ports 17 and 19, and the fermentation container l The air passes through the inside of the exhaust fan 14 and is discharged from the exhaust fan 14.

By taking in outside air and passing it through the fermentation container 1 in this way, the heat and moisture generated inside can be absorbed, and the air that has absorbed this heat and moisture can be exhausted from the exhaust fan 14. be.

Also, as shown in FIGS. 2 and 9, the exhaust fan 14
A water droplet trap 22 is provided at the bottom of the exhaust pipe 13, and when the water absorbed by the air and about to be discharged is exposed, adsorbed to the exhaust pipe 13, and becomes water droplets, the water drop trap 22 is installed at the bottom of the exhaust pipe 13. This makes it possible to absorb it at 22.

The water droplet trap 22 also serves as a cleaning port for the exhaust port and a port for removing dirt and the like.

4 to 8, the configuration of the opening/closing pedal 20 and the opening lock lever 25 is disclosed.

After pushing the opening/closing pedal 20 in order to open/close the working machine, the opening/closing pedal 20 is rotated by rotating the opening/closing lever 25 and engaging the locking pin 29 with the locking lever at the bottom of the opening/closing lever 25. The depressed position, that is, the open position of the input port cover 3 is maintained.

Garbage is put in with the input port lid 3 open.

When closing the input port 3, open the opening lid 2.
5 forcibly to release it, or by depressing the opening/closing pedal 20 to the lock release pedal 28.
The lock release pedal 28 is released.

Further, the input port lid 3 is pivotally supported by an input port rotation shaft 30, and an input port opening/closing switch 24 is disposed at a portion of the input port rotation shaft 30.

The input port cover opening/closing switch 24 detects the open state of the input port cover 3 and stops the rotation of the drive motor 10, as shown in the control circuit diagrams of FIGS. 10 and 11.

The input opening/closing switch 24 may be constructed so as to come into direct contact with a limit switch, as in the embodiment shown in FIG. It may also be a proximity switch that senses the proximity of the lid 3.

Further, as shown in FIG. 4, it may be a limit switch 24b that detects depression and rotation of the opening/closing pedal 2o.

In addition, a temperature control device 32 is installed inside the fermentation container 1, and if the inside of the fermentation container 1 becomes too low, the fermentation will be sluggish.
The temperature inside the fermentation container 1 is controlled to be optimal for fermentation by controlling the blower 11 on and off.

A timer 31 is also provided to set the rotation time of the stirring claw 5.

(F) Effects of the Invention Since the present invention is constructed as described above, it has the following effects.

According to claim (1), in the configuration in which the exhaust fan 14 for forced exhaust is provided to remove heat and moisture inside the fermentation container 1, the exhaust port 15 equipped with the exhaust fan 14 is provided at the upper part of the fermentation container 1. In addition, since the opening is in the center near the partition plate 7, inside the fermentation vessel 1, the front part of the partition plate 7 is the most active part of fermentation, and heat and moisture are the most active in this part. However, by arranging the exhaust port 15 between the central part of the fermentation vessel 1 and the partition plate 7, heat and moisture can be efficiently exhausted by the exhaust fan 14. Therefore, the volume of the final compost can be reduced.

Furthermore, if the exhaust port 15 is opened in a portion below the input port lid 3 where initial fermentation has not yet been completed, the odor of food waste will still be strong in that portion, and this will be sucked and discharged by the exhaust fan 14. However, by providing the exhaust port 15 near the center of the fermentation container 1 at the front of the partition plate 7,
This problem has been resolved.

According to claim (2), an input port 33 and an input port cover 3 are provided in the upper part of the fermentation container 1, opening and closing of the input port cover 3 is detected by an input port opening/closing switch 24, and a stirring claw is activated based on the opening of the input port cover 3. Since the rotation of the stirring claw 5 is configured to stop, when the operator opens the input port 3, the rotation of the stirring claw 50 is always stopped, so even if the operator inserts his/her hand into the stirring claw 5, there is no risk of injury from the stirring claw 5. This makes it possible to create a safe organic waste treatment device.

In addition, when the input port lid 3 is opened and food waste is thrown in, if the stirring claw 5 is rotating, there is a problem in that the food waste to be thrown in and the waste that is being rotated are thrown out. Since this situation does not occur, fermentation vessel 1
This made it possible to improve the working environment around the machine.
