ABSTRACT:
The present disclosure relates to improvements in dust collection apparatus, which apparatus has a dividing wall, which serves to define a high pressure side and a low pressure side. The wall comprises a plurality of filter bags which bags are mounted in a generally vertical plane and with each bag having an open end defined by two flaps. The flaps on adjacent bags are mounted on vertically extending support members commonly referred to as mullions and other means are provided for supporting the closed ends of the bags. The disclosed improvements herein include a new spacer member for insertion into the bags from the open end thereof to keep the bags from collapsing during operation of the dust collection apparatus. An additional improvement is that of a protective shield which has a generally U-shaped cross section which is adapted to fit over and around flaps on adjacent filter bags which flaps are supported by a given mullion between adjacent bags. Another part of the disclosure has to do with the construction of an air seal strip which is for the purpose of preventing air flow through a given opening in a given filter bag. This construction is for the purpose of permitting overall operation of the dust collection apparatus while preventing flow through a given filter bag which may have been damaged, thus permitting the passage of dust therethrough.
