Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to agitating (mixing) organic waste in a waste decomposition treatment facility for fermenting and decomposing organic waste such as household garbage, livestock manure, and sewage sludge. Alternatively, it relates to a stirring / raising device for raking sediments in maintenance equipment such as dams and sewage treatment plants.

[0002]

2. Description of the Related Art Heretofore, as this type of agitating / raising device, an agitator for a waste treatment device described in JP-A-11-104602 has been known. This agitator moves in a storage tank and agitates the organic waste introduced into the storage tank, and is wound between a pair of sprockets vertically spaced apart on a vertical or inclined axis. A chain, a main body of a stirrer that is arranged inside the core chain and connects the sprockets, and is attached to a plurality of positions in the circumferential direction of rotation of the chain, and when the chain is rotationally driven, the organic waste in the storage tank is scraped up. A frying member, wherein the frying member has a stirring blade for scooping up organic waste when protruding to the outside of the chain, and an abutting member that is inclined and fixed to the stirring blade, and The stirrer is rotatably attached to the chain with a horizontal shaft, and the stirrer is within the movement trajectory of the frying member on the front side in the traveling direction of the stirrer when the chain is rotationally driven. The agitating blades are projected by the abutting member abutting and fixing to the protruding scraper arranged in the above, and the stirring blade is agitated on the pushing scraper located outside the movement trajectory of the flight member other than the upper part of the agitator or the rear side in the traveling direction. The stirring blade is configured to be pushed toward the movement locus side by rotating by contact with the blade, and the pressure receiving plate arranged on the rear side in the traveling direction of the stirrer is in sliding contact with the outside of the flight member. It is configured.

According to the stirrer having the above structure, the stirrer of the flight member is projected by the projecting scraper, and the stirrer is pushed inward by the pushing scraper to prevent the projecting. On the rear side in the direction, since the outside of the flight member slides on the pressure receiving plate, it is possible to prevent the organic waste from entering between the pressure receiving plate and the flight member, which allows the organic waste to adhere to the agitator body. Can be reduced, and the operating performance of the agitator can be reliably maintained. Further, contact between the flight member moving on the rear side in the traveling direction and the organic waste can be prevented, and unnecessary drive resistance can be prevented from acting on the stirrer, and the mechanism for driving the stirrer can be downsized and at low cost. Can be converted. Furthermore, the sliding contact between the pressure receiving plate and the flight member reliably prevents rotation of the flight member that moves rearward in the traveling direction, and the stirring blade does not project to the outside. It has excellent effects such as improvement of operating accuracy, reduction of failures, and extension of life.

[0004]

However, the conventional stirring and
In the scraping device, the stirring blade of the flight member for scraping up the object to be treated (organic waste) has a horizontal plate shape on the chain rising side (front side in the traveling direction of the stirrer).
The amount of scraping of the object to be processed depends on the size of the stirring blade, and if the area of the stirring blade is increased to increase the amount of scraping, the scraping is performed while pressing the object to be processed. , There is a problem that the drive power of the chain becomes large. In addition, the protrusion of the stirring blade may start below the stirrer, and the scraping may be performed while pressing the object to be processed as described above, so that the stirring and scraping device pushes it upward. Since the force acts intermittently, there are problems that vibration and noise are generated and that the stirring and scraping device is worn out early.

Therefore, according to the present invention, it is possible to increase the amount of stirring and scraping of the object to be processed without increasing the driving power of the chain, reduce the generation of vibration and noise, and achieve a long service life. The main purpose is to provide a scraping device.
