<P>PROBLEM TO BE SOLVED: To provide an air seal device capable of effectively releasing an air seal bar with an air seal spring held in a contracted state from the contracted state. <P>SOLUTION: The air seal device airtightly connects a pallet truck 1 of a Dwight Lloyd type sintering machine and a wind box by an air seal bar 12 which is attached to the bottom surface of the pallet truck 1 and is biased toward the distal end face of the wind box to keep a slide state to the distal end face. A forced operation mechanism is added to give vibrations in the biasing and counter-biasing directions to the air seal bar 12 through an electromagnet 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
