It is bent to the right by 45 ° to 60 ° to have a shape of a tip bent portion approaching the inner peripheral surface of the processing tank, and the wings with a scraping plate are the same from the same linear mounting portion as the single plate wings. It bends on a plane and extends in the shape of a sickle, and its tip is the tip hypotenuse whose front-side corner in the rotation direction approaches the inner peripheral surface of the processing tank and gradually moves away from the inner peripheral surface of the processing tank toward the rear side. The two plate-like arms are arranged in parallel at a predetermined interval, and a horizontally long scraping plate projecting right and left at both ends from the two plate-like arms is fixed to the tip oblique side.

A plurality of single veneer blades alone and a plurality of single veneer blades and a plurality of blades with a scraping plate are alternately arranged at a plurality of locations where the axial direction of the rotating shaft is divided at equal intervals. At appropriate intervals in the circumferential direction, the left and right directions of the tip bending portion of the single wing are arranged so that adjacent ones are in the opposite direction as much as possible, and the mounting portion is radially fixed or detached. It is a stirring and crushing device for garbage disposal that is installed as possible.

[0007] The single plate wing and the scraper-equipped wing are attached to the rotating shaft by a plurality of attachments at a plurality of locations where the axial direction of an outer cylinder fitted on the outer periphery of the rotating shaft is divided at equal intervals. In some cases, the seats are protruded radially, and the mounting portions of the single plate wings and the wings with the scraping plate are detachably mounted on the mounting seats.

[0008]

Embodiments will be described with reference to the drawings.
In FIG. 1, an outer cylinder 5 is fitted around an outer periphery of a rotating shaft 1 provided laterally on an axis of a cylindrical tank-shaped processing tank, and the outer cylinder 5 is divided at equal intervals in an axial direction of the outer cylinder 5. At the A, C, E, and G positions shown in FIG. 1, a single plate blade 3 shown in FIG. 3 and a scraping plate shown in FIG. The wings 4 are detachably attached one by one,
At the positions D and F, only the single plate blade 3 is detachably mounted at a position equally divided into three parts on the circumference, and as shown in FIG. 2 viewed from the end of the rotation shaft indicated by the arrow P in FIG. Is attached in such a manner that it is bent in the direction of rotation at every 30 ° circumferential angle, and the
Each time it is bent in the anti-rotation direction.

The single plate blade 3 is made of a stainless steel plate.
As shown in FIG. 2, a straight bent portion 3a refracts in the lateral direction and extends in a sickle shape, and the tip portion is formed as a tip bent portion 3b bent about 50 ° to the right or left as shown by a solid line and a virtual line.

The scraper-equipped wing 4 is also made of a stainless steel plate, and has the same linear mounting portion 4a as the single-plate wing 3 as shown in FIG.
From the processing tank inner peripheral surface 2 at the front end side in the rotation direction of the front end.
, And two plate-like arms 4c, each having a tip oblique side 4b gradually approaching the rear side from the inner peripheral surface of the processing tank, are arranged in parallel at a predetermined interval, and two plate-like arms 4c are attached to the tip oblique side 4b. A horizontally long end plate 4d projecting from both ends to the left and right is fixed.

In this embodiment, the mounting seat 6 is provided on the outer cylinder 5 fitted to the rotary shaft 1, but the mounting seat 6 can be provided directly on the rotary shaft 1.

Prior to the development of the present invention, the first prototype shown in FIG. 5 in which nine simple stirring arms in the form of a rod were dispersed and arranged radially around the rotation shaft in the same processing tank as the present invention, A prototype No. 2 unit shown in Fig. 6 in which a stir arm with a small scraper attached at right angles to the ends of two rods parallel to the outer periphery of the shaft at narrow intervals is arranged at nine positions, and a little wider around the outer periphery of the rotating shaft. The prototype shown in Fig. 7 in which a scraper plate larger than the No. 2 unit shown in Fig. 6 is attached to the tip of an arm in which steel plates parallel to each other are cut out in the shape of a "-" and tilted forward and downward with respect to the rotation direction. The result of manufacturing the No. 3 machine under the following test conditions is shown below together with the results of the present invention.

Test conditions Type of garbage Living garbage (moisture ratio: about 40%) Processing amount per processing 50 kg Microbial cell amount: about 175 kg (about 470 liters) Temperature in processing tank 40 ° C. to 50 ° C. Rotation speed 8 rpm

Test Results Prototype No. 1 The garbage was insufficiently stirred and pulverized, remained stationary at the bottom of the treatment tank, and did not move, and generation of offensive odor was recognized over time. Prototype No. 2 Although the decomposition time of garbage was efficiently eliminated in about 6/3 hours, which is about 2/3 of that of Prototype No. 1, garbage (for example, beef meat) that was difficult to decompose remained, and in some cases, a bad smell was generated. . Prototype No. 3 Decomposition of garbage was very fast, mixing with microbial bacteria was performed smoothly, processing time was reduced to 4 to 5 hours, and generation of offensive odor was small. Decomposition time of the present invention garbage was almost the same as that of prototype No. 3,
The stirring and crushing became finer, and the odor was further reduced.

[0015]

The present invention is embodied in the form described above and has the following effects.

The single plate wing and the wing with a scraping plate form a long arm that rises from the outer periphery of the rotating shaft and refracts or bends laterally to approach the inner peripheral surface of the processing tank. To increase the stirring and crushing capacity,
The processing cost can be reduced.

Since the tip of the veneer blade is bent to the left or right, the agitation of garbage is promoted, and the garbage is averaged by moving the garbage in the left-right direction. Crushing and mixing can be promoted by the action of pressing and crushing.

The wings with a scraping plate increase the stirring and crushing efficiency by scooping and dropping a large amount of garbage with a scraping plate having a large area, and have the effect of pressing the garbage against the inner peripheral surface of the processing tank on the outer surface to crush it. In addition, the effect of stirring and pulverizing can be greatly increased.

By providing a mixture of single-panel wings and wings with a scraping plate having different functions as described above, the stirring and pulverization of garbage can be further finely promoted to mix with microorganisms, and solids can be eliminated in a short time. The processing can be performed more quickly and reliably, and the generation of offensive odor can be prevented.
