摘要

PURPOSE: To automatically clean a bag filter without detaching it from the supporting means by making the supporting means to which the bag filter is fixed reversible and providing plural cleaning nozzles to clean the bag filter capable of being automatically rotated. ;CONSTITUTION: When a bag filter 1 fixed to a fluidized-bed device such as granulator and coater is cleared, the filter 1 fixed to a supporting seat as the supporting means is transported into a cleaning chamber 2 by a truck, etc., and then the seat 3 is placed on the carrying part of a reversible frame 4a of a holding means 4. The door of an external cleaning chamber 2 is closed, an upper cleaning nozzle 9a is rotated to inject hot water, hence the filter is cleaned, and then hot water is injected from side and lower nozzles 9b and 9c to clean the bag filter. The reversible frame 4a is then rotated around its axis to reverse the filter 1, and a turntable 4b is rotated by a motor 8 to apply the second cleaning.;COPYRIGHT: (C)1996,JPO
