[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a food waste treatment device that ferments food waste, especially prepared foods, with aerobic thermophilic bacteria, decomposes and eliminates the food waste in a short time, and decomposes it into water and carbon dioxide.

[0002]

[Prior art]

 In the conventional food waste treatment equipment, a stirring rod was attached to the rotary shaft in the treatment tank or a single spiral blade was installed to stir in one direction and air was taken in from the upper part of the treatment tank.

[0003]

[Problems to be solved by the device]

 In order to decompose and eliminate raw garbage due to aerobic thermophilic bacteria in the raw garbage processing equipment, sufficient stirring and grinding of raw garbage and uniform air supply are essential conditions. Therefore, conventionally, agitating rods are attached to the rotating shaft or the garbage is agitated with a spiral blade.However, since the stirring direction is one direction, the movement of the garbage is also in a fixed direction, and the aerobic hyperthermia The contact was insufficient, and it took time to disassemble and eliminate the garbage.

Further, since the air was taken into the treatment box from the upper part, it was not possible to uniformly introduce the air introduction holes from the upper surface of the treatment box, and contact with aerobic thermophilic bacteria was not possible. It was enough, and the reproduction of bacteria was weak.

From the above point of view, the present invention is capable of easily agitating and crushing raw garbage, introducing air evenly, proliferating aerobic thermophilic bacteria, and capable of decomposing and eliminating raw garbage in a short time. It is intended to provide a waste disposal device.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the device of the present invention is provided with a rotary shaft from one side to the other side of a processing box having a garbage input port at the top and a large number of air introduction holes at the bottom. In order to convey garbage from the center of the box to the sides, spiral coil type blades with opposite spirals are provided facing each other from the both ends of the rotating shaft, and the spiral coil type blade is located on the rotating shaft. Are installed separately from each other in the same direction, coaxial with the rotating shaft, and are placed in the opposite direction from the both ends of the rotating shaft to the outside of the spiral coil type blade so as to convey the garbage toward the center from the side of the processing box. Large spiral coil type blades having a spiral are provided facing each other, and the large spiral coil type blades are installed in the spiral coil type blades in a radial direction, and a large number of cutting blades are provided on the large spiral coil type blades. It is, and is characterized in that the fixed blade with the cutting blade is provided on the inner wall of the processing chamber.

[0007]

[Action]

 Explaining the operation of the device of the present invention, raw garbage is put in from the inlet of the processing box to mix aerobic hyperthermia. Out of the blades that are double mounted on the rotating shaft in the processing box, the garbage is transported to both sides from the center of the processing box by the inner spiral coil type blade, and also the large spiral coil outside the spiral coil type blade. Since it is conveyed from the side of the treatment box toward the center by the mold blade, it circulates on both sides from the center of the treatment box, resulting in complicated agitation and good contact with bacteria.

Further, since the spiral coil type blade is provided separately from the rotating shaft and the large spiral coil type blade is provided separately from the spiral coil type blade in the radial direction, even if a large amount of raw dust is introduced, Since raw garbage can enter and pass inside the blade, it rotates smoothly without overloading the drive unit, and the circulation of raw garbage is also smooth.

Further, since the large spiral coil type blade is provided with a large number of cutting blades, raw garbage can be finely cut, and since the blade is also provided on the inner wall of the processing box, the raw garbage circulating while being stirred Is efficiently cut by both blades.

Furthermore, since the treatment box has a large number of air introduction holes at the bottom, air is uniformly introduced from the entire bottom surface of the treatment box, and aerobic thermophilic bacteria proliferate.
