Bag house filters and bag section repair and replacement kit

Abstract

An improved multiple segment baghouse filter, and a kit and method for replacing or repairing existing, damaged baghouse filters. Instead of removing and replacing the entire length of a damaged filter, a separate repair portion is spliced into the filter. A damaged bag section is removed, and the undamaged remainder is trimmed and folded. The kit has a spool-like splicing drum that forms a junction between the undamaged and damaged repair sections. The molded plastic splicing drum comprises a central, reduced diameter annular region from which a pair of diverging edge segments integrally extend. The outwardly flared wedge portions terminate in lips that aid in securing filter segment ends which are drawn over the lips and retained upon the wedge segments. The new filter design employs the splicing drums as original equipment, reducing the complexity and difficulty of subsequent filter repairs.
