Document Type and Number:
Japanese Patent JP2919686
Kind Code:
B2
Abstract:
PURPOSE:To provide the front door of a solvent recovery type drier surely sealing an insertion port connected to the inside of a rotary drum, releasing the internal pressure of the rotary drum with a simple structure, and facilitating the opening/closing actions. CONSTITUTION:A latch 33 provided on one side of a door plate 2 covering an insertion port 1a opened on a front plate 1 and connected to the inside of a rotary drum 10 is coupled with a fixing plate fixed to the front plate 1 at a gap S, and the door plate 2 can be moved within the range of the gap S. During the drying operation when the inside of the rotary drum 10 has negative pressure, a circular packing 4 on the periphery of the door plate 2 is pressed to the front plate 1 by the suction of the negative pressure, and the insertion port 1a is sealed. When the internal pressure of the rotary drum 10 rises due to the ignition and explosion of a gasified solvent, the door plate 2 pressed by the internal pressure is moved in the opening direction within the range of the gap S, and the internal pressure is released via the gap S generated between the circular packing 4 and the front plate 1.
