BELLOWS PIPE

摘要

PURPOSE: A new type of bellows pipe is provided to minimize the deposition of powder on a corrugated case and to make easy the cleaning. CONSTITUTION: A bellows pipe(10) is composed of a first and a second flanges and a socket type slide tube. Herein, the path of the bellows pipe is formed in straight line by the slide tube so that the flow of fluid is smooth. And powder is deposited on the inner face of the slide tube not on the corrugated part(12a) of the corrugated case. Then, the amount of the powder is small because of the smooth flow of fluid. The powder deposited in the bellows pipe can be reduced by cleaning after separating the slide tube. And the cleaning of the corrugated case is easy according to the small amount of powder deposited in the corrugated case.
