Abstract
A filter apparatus for use with a fluid bed processor includes a movable filter bundle that can be selectively moved within a fluid bed chamber. The movable filter bundle includes one or more filters attached to corresponding filter mounts on a support structure. The movable filter bundle may also include an index rod that rotationally secures the movable filter bundle when in a first position. A support assembly can be used to connect the movable filter bundle to the fluid bed chamber. In the first position air is filtered through the filters in the process operation of the filter apparatus. In a second position individual filters on the movable filter bundle can be easily inspected, serviced, and/or replaced.
Claims26
A filter apparatus for filtering process air generated by a fluid bed granulator, coater, or dryer comprising:
- a fluid bed chamber;
- a filter mount transport mechanism, the filter mount transport mechanism including at least one filter mount for receiving a filter, the filter mount transport mechanism having:
- a first position wherein the filter mount is in position for filtering process air;
- and
- a second position wherein the filter mount is in position for filter servicing.
A filter apparatus for filtering process air generated by a fluid bed granulator, coater, or dryer comprising:
- a fluid bed chamber;
- a movable filter bundle within the fluid bed chamber, the movable filter bundle having a raised position and a lowered position, wherein in the raised position the movable filter bundle is in position for filtering process air and in the lowered position the movable filter bundle is in position for filter servicing, the movable filter bundle comprising:
- a support structure;
- a filter mount;
- an attachment block;
- an index rod;
- and
- at least one filter unit for filtering process air generated by a fluid bed granulator, coater, or dryer, the filter unit having a fastening device to attach the filter unit to the filter mount;
- a support assembly attached to the attachment block for selectively raising and lowering the movable filter bundle within the fluid bed chamber;
- and
- at least one index rod receiver attached to the fluid bed chamber for receiving the index rod and thereby placing the movable filter bundle in a desired rotational position while in the raised position.
A method of servicing filters in a filter apparatus, comprising:
- providing a fluid bed chamber within a filter apparatus, the fluid bed chamber having a movable filter bundle in a first position within the fluid bed chamber, the movable filter bundle having at least one filter attached thereto;
- selectively moving the movable filter bundle to a second position;
- and
- servicing the at least one filter while in the second position.
