Abstract
A fluidized bed apparatus includes: a filter casing unit attached to a support base so as to be vertically movable; and a spray casing unit attached to the support base so as to be swingingly movable. The filter casing unit is, while being inverted, vertically moved under a state in which the spray casing unit is withdrawn sideways, and a filter is replaced at a maintenance position (Y) on a lower side of the apparatus. The filter casing unit is attached to a base plate of a lifting device. When a lift plate ascends while being placed on a screw nut, the filter casing unit also ascends. The filter casing unit is not fixed to the lifting device and is not distorted even when the unit cannot be sandwiched with an equal force.
