It may be formed in a shape that is long in the rotation axis direction, such as a horizontally long rectangular cross section or a rhombic cross section.

The inter-transport-section stirrer 21 stirs organic waste and sawdust mainly in the circumferential direction of the rotating shaft. If necessary, the organic waste and sawdust are stirred in the circumferential direction of the rotating shaft. It may be formed in such a manner that it is stirred in the direction and also conveyed in the axial direction.

The agitating portion 22 on the side of the processing tank has a main agitating rod portion 2 fixed to both sides of the rotating shaft 2 so as to protrude substantially symmetrically.

Between the end portion of the blade 11 and the side surface portion 1a-1 of the processing tank 1, a stirring-only area W2 for stirring the organic waste and sawdust only in the circumferential direction without being transported in the rotation axis direction is partially secured. ing.

The main stirring rod portion 22a is made of a long metal plate having a rectangular cross section, and is welded to the rotating shaft 2 by penetrating the rotating shaft 2 at a substantially central portion thereof. The organic waste and sawdust are stirred in the circumferential direction of the rotating shaft 2.

The reinforcing stirrer 22b receives the reaction force of the organic waste and sawdust conveyed by the spiral blade 11 from the side 1a-1 of the processing tank 1 because the main stirring bar 22a receives the reaction force.

It is set as appropriate according to the above.

According to the decomposition apparatus A having the above structure, the organic waste put into the processing tank 1 is conveyed along with the sawdust previously stored in the processing tank 1 in the rotation axis direction. At the same time, it is also stirred in the circumferential direction of the rotating shaft 2.

At this time, in the area W1 having the axial transport section 10 in the rotation axis direction, organic waste and sawdust are transported in the rotation axis direction by the helical blade 11 and the plate-like blade 12 of the axial transport section 10.

That is, even if the organic waste and the sawdust are densely packed in the processing tank to form a dumpling, the rotation of the stirring unit 21 between the transport units and the stirring unit 22 on the side of the processing tank causes the dumping of the organic waste. And the sawdust is broken and stirred in the circumferential direction. Therefore, the helical blade 11 and the plate-shaped blade 12 are reduced in the load received from organic waste and sawdust, and are free from breakage and deformation.

Next, an apparatus for decomposing organic waste in the embodiment shown in FIGS. 5 and 6 will be described. This decomposition processing device B

While stirring in the circumferential direction, the organic waste and sawdust that are to adhere to the bottom plate 1b are scraped off.

The manner in which the stirring plate 23b is provided on the bar 23a is not limited to the above, and as shown in FIG. The direction stirring efficiency may be further improved.

The decomposition processing apparatus B is used in a range in which organic waste and sawdust are particularly likely to be dense and tend to form a dumpling, that is, the end of the axial transfer section 10 in the rotation axis direction and the processing tank 1 facing the end. A wide stirring-dedicated area W2 is secured by disposing the processing tank side stirring part 22 and the rod-shaped stirring part 23 between the inner side part 1a-1 and the stirring efficiency in the circumferential direction is improved. is there.

Therefore, in order to further improve the stirring efficiency in the circumferential direction according to the use of the decomposition processing apparatus B, the number of the bar-shaped stirring portions 23 is increased in the direction of the rotation axis so that the dedicated stirring region W2 is formed. What is necessary is just to comprise so that it may secure wider.

It is effective that the area dedicated to the stirring area W2 is secured so that the organic wastes and sawdust are particularly likely to be densely packed. Is not limited between the end in the direction of the rotation axis and the side 1a-1 in the processing tank 1 facing the end. For example, depending on the use of the organic waste decomposition treatment apparatus, the mode of the axial transfer unit, and the like, the stirring-only area W2 is
It may be provided between the left and right axial conveyance units 10 in the decomposition processing apparatus A or the decomposition processing apparatus B, or each of the left and right axial conveyance units 10 may be divided at an intermediate portion in the rotation axis direction, and May be provided.

In the above embodiment, by eliminating the agitating section 21 between the transport sections, the area W1 is made a transport-only area having only the axial transport section 10, and the transport-only area and the agitation-only area W2 are combined. May be used to configure the inside of the processing tank 1.

Decomposition processing can be performed efficiently. Moreover,
Since the circumferential stirrer stirs the organic waste and sawdust conveyed by the axial transfer unit in the circumferential direction, the organic waste and sawdust are unevenly concentrated in the treatment tank and are pressed by the transfer force of the axial transfer unit. It can be prevented from being lumped and lumped. Therefore, there is no fear that the blades constituting the axial conveying section are damaged or deformed by the reaction force of the hardened organic waste and sawdust.
