Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary garbage decomposing / disassembling apparatus, which is used when decomposing household or commercial garbage.

[0002]

2. Description of the Related Art A conventional garbage disposal apparatus of this type is configured to rotate a cylindrical tank about its axis, and a bed containing garbage decomposing bacteria together with garbage in the cylindrical tank. Then, the garbage is decomposed by the action of the decomposing bacteria while the garbage and the bacterial bed are stirred and mixed by rotating the cylindrical tank about the axis. A ventilation pipe having a required number of ventilation holes is installed at the axis of the cylindrical tank to send air into the cylindrical tank to remove gas generated during fermentation of garbage.

[0003]

However, in such a conventional garbage processing apparatus, since the blower tube is installed in a cylindrical tank, the blast pipe is buried by bacteria beds and garbage during rotation of the cylindrical tank. As a result, the ventilation holes are easily clogged, and as a result, it is difficult to send air into the cylindrical tank, and thus it is difficult to efficiently remove gas generated during the fermentation of garbage.

An object of the present invention is to eliminate these disadvantages.

[0005]

In order to achieve the above-mentioned object, in the rotary garbage decomposition apparatus according to the present invention, a cylindrical tank is formed by a cylindrical body and a pair of bottom plates closing both openings of the cylindrical body. And a support shaft protruding outward at a substantially central portion of each of the bottom plates, and these support shafts are appropriately supported by bearing means and the cylindrical tank is appropriately rotated in a circumferential direction by rotating means. Rotatable, a bacterial bed is provided in the cylindrical tank, a garbage decomposing bacterium is blended into the bacterial bed, and the garbage is decomposed by the decomposing bacteria. The bacteria-bed room, the upstream-side warm air room and the downstream-side warm air room are separated by a ventilable partition plate, and these warm-air rooms are arranged on both sides of the bacteria-bed room, and the support shaft is formed into a cylindrical body. The upstream warm air through the lever shaft The hot air is supplied to the downstream side and the hot air is discharged from the downstream side hot air chamber. As a result of being open to the room air, warm air is blown from the upstream warm air chamber through the open portion of the partition plate.

If a drain is provided in the upstream warm air chamber, moisture generated during the fermentation of the garbage can be drained out of the cylindrical tank.

Further, if the end of the spindle is slightly projected from the bottom plate of the cylindrical tank, debris accumulated in the upstream warm air chamber or the downstream warm air chamber enters the inside of the spindle. Can be prevented.

Further, an inlet is provided in the bacterial bed chamber of the cylindrical tank, and the cylindrical tank can be stopped with the inlet facing obliquely upward, and the height of the stop position can be adjusted appropriately. Further, if the cylindrical tank is configured such that the input port rotates downward and forward, the input amount of garbage into the bacteria bed chamber is adjusted at the level of the input port (low position). In this case, the height of the inlet can be set in advance according to the type of garbage to be decomposed. For example, when the amount of water contained in the garbage is small, it is set to a high position according to the processing capacity, and when it is large, it is set to a low position where the amount of garbage needs to be reduced. In addition, if the cylindrical tank is configured such that the charging port is rotated toward the lower front side, when the cylindrical tank is stopped, garbage (decomposed material) is removed from the charging port of the cylindrical tank. Garbage (decomposed product) because it accumulates on the other side
Is not spilled from the slot.

[0009] Further, if the inlet of the cylindrical tank is rotated downward and forward, the turnbuckle contacts the cylindrical tank even when the turnbuckle for closing the cover of the inlet is released. In a state where no space is taken, in order to rotate the side opposite to the inlet upward, when a heating means is provided on the back side of the stop position of the inlet, a gap between the heating means and the cylindrical tank is provided. As a result, the heating effect of the heating means on the cylindrical tank (bacterial bed chamber) is improved.
