SUCTION AND EXHAUSTION STRUCTURE OF GARBAGE TREATING MACHINE

摘要

PROBLEM TO BE SOLVED: To sufficiently supply oxygen to every part of a material to be treated in a fermentation tank and to sufficiently exhaust a generated gas by providing an exhaust port at the upper part of one side face of the fermentation tank and a suction port at the upper part of the other side face, extending the lower end of the inner periphery of a garbage inlet below the upper end of the opening of the tank and arranging the suction port above the lower end of the inner periphery of the inlet. SOLUTION: The garbage inlet 10a is formed in the center of the upper part of a casing 10 and made freely closable by a feed lid 12. The cylindrical inner periphery of the inlet 10a is inserted into the inlet 1e of a fermentation tank 1 and extended downward. A suction port 1h is formed at the upper part of the left side face of the tank 1 and an exhaust port 1a at the upper part of the right side face. The suction port 1h is positioned higher than the lower end of the inner periphery of the inlet 10a so that the air outside the machine is hit against the inlet 10a and flows downward. An exhaust fan 21 is provided outside the exhaust port 1a, and a filter 60 is furnished to the exhaust port 1a.
