Field of the Invention The present invention relates to an improvement of an apparatus for stirring a raw material in a fermentation tank for sludge or the like. In particular, in the present invention, the fermentation tank is formed in a loop shape, and the stirring apparatus is turned around a circular portion. It is an object of the present invention to provide an apparatus capable of uniformly stirring a raw material in a circular portion in a fermenter that needs to perform the process.

JP-A-8-67588 is one such example. In Japanese Unexamined Patent Publication No. Hei 8-67588, a stirrer mounted on a bogie reciprocates in a linear portion of a fermenter and turns around an inner end of a circular portion.

撹拌装置の機枠との間に隙間が必要である。特に、撹拌
装置が旋回する部位では、撹拌装置のスクープにかかる
負荷が不均衡となるため、直線移動部よりも大きな隙間
が必要である。However, in the above-mentioned apparatus in which the stirring device operates and patrols the inside of the fermentation tank, the side wall of the fermentation tank and the frame of the stirring apparatus are required to move the stirring apparatus smoothly. There must be a gap between them. In particular, at a portion where the stirrer turns, the load applied to the scoop of the stirrer becomes unbalanced, so that a gap larger than that of the linearly moving portion is required.

The raw material that has been thrown toward the dent flows backward through the gap,
This is scooped up again and stirred. That is,
In the conventional apparatus, uniform stirring cannot be performed due to the deviation of the raw material and the backflow of the stirred raw material in the swirling part of the stirring apparatus.

In a fermenter configured as a loop in a plan view, in a fermenter equipped with a scoop-type stirring device that circulates in the tank while scooping up the raw material at the bottom of the tank and throwing it backwards, the intermediate partition wall of the fermenter The center of rotation of the scoop-type stirrer is provided at the center line of the scraper, and a scraper is fixed to the inner machine frame of the scoop-type stirrer in a direction parallel to the center axis of rotation, and the inner edge of the scraper is positioned at the center. It is slid on the partition wall.

Seal the gap between the wall. Therefore, the thrown raw material does not flow backward and remix, and the raw material can be uniformly stirred even in the swirling section. Hereinafter, the present invention will be specifically described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an endless scoop belt having a large number of scoops 1a mounted thereon, and reference numeral 2 denotes left and right sides of the scoop belt 1. A cover 3 covering the inner and rear portions is a scraper attached to the cover 2 on the inner end side of the scoop belt 1, and its inner edge 3a has an intermediate partition wall of the fermenter 4 as shown in FIGS. 4a.

Throw it backwards and stir and transport at the same time. At this time,
In the revolving portion of the stirring device A, the raw material in the central portion of the rotation is thrown toward the rear outer peripheral portion, and a hollow is formed in the central portion of the swirl, and the raw material thrown toward the hollow forms a backflow. At this time, according to the present invention, since the scraper 3 is provided in the gap where the raw material flows backward, the backflow of the released raw material can be prevented.
