Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for charging raw materials for composting, such as municipal waste, sewage sludge, and accumulated waste, into a fermentation tank.

The composting raw materials are fed into the fermentation tank using a mixer, a conveyor, a chute, or a combination of these.In the normal method of feeding the composting raw materials into the fermentation tank, the composting raw materials are deposited in dots or lines according to the angle of repose. A separate method and device is required to disperse the material by simply adding it to the fermenter, and there may be a problem that the device for switching the raw material in the fermenter interferes with the device for feeding the composting raw material, and the There are cases where it is not possible to switch the raw materials back and forth using mechanical equipment.

The above-mentioned problem with feeding the composting raw materials into the fermentation tank is that the invention related to Japanese Patent Application No. 184538/1984, ``Composting Raw Material Supply Device'', uses a rotating paddle that projects the raw materials into a long distance at the raw material receiving end of the fermentation tank. A composting raw material supply device characterized in that the rotary paddle is configured to move in a direction substantially perpendicular to a direction in which the raw material is projected.

Thus, by providing a rotating paddle in the fermentor charging section, the invention of this earlier application not only made it possible to uniformly charge a large amount of raw materials, which was not possible with Juute, etc., but also achieved this with a very compact device. In addition, since the raw material is crushed or chipped by the paddle and scattered in the form of particles, it is possible to provide a feeding device for composting raw materials that is soft to deposit and can prevent the consolidation of raw materials due to input, making it practical. Above all, it is extremely effective.

However, if the device of the prior invention is installed in a sealed fermentation tank, the worker will have to enter the fermentation tank directly for inspection and maintenance, and will be exposed to high temperatures, odors, and harmful gases. .

Conventionally, as shown in Japanese Utility Model Application Publication No. 53-122032, there has been a system in which outside air is introduced into a factory building and exhausted from the factory building, but this is effective in improving the working environment. , the high-temperature air and harmful gases generated in factory buildings are only diluted, and it cannot be used effectively in compost fermentation rooms, etc., where strong odors and harmful gases are generated.
Disadvantages include the need for large amounts of air, which lowers the required fermentation temperature and introduces excess breathing air.

The present invention provides inspection of the composting raw material input device in a closed fermenter equipped with a conventional composting raw material input device,
The purpose is to provide a closed fermentation tank that can be maintained in a well-maintained environment.

In the present invention, a raw material charging chamber is provided adjacent to the fermentation chamber on one side of the closed fermentation tank, a slit for inputting the raw material is provided in the partition wall between the raw material charging chamber and the fermentation chamber, and a raw material charging device is installed along the slit. The rotary paddle is movable, and in an embodiment, the material input chamber is further provided with a chamber at both ends for inspection and maintenance of the device for turning over the composting material in the fermenter. be.
