Abstract
A damper assembly for use with the inlet duct of a pollution control system includes a plurality of vanes which are pivotally mounted for movement between an open position and a closed position wherein the vanes coact to close the duct. Each vane is pivotally mounted at one end on a closure plate releasably affixed over an opening sized to permit the vane to be removed therethrough. The vanes also include a hanger member receivable on a trolley rod which may be inserted into a second opening in the duct for supporting the vane after it has been disconnected from its pivot support and as it is being slid through the opening and into and out of position within the duct.
Claims10
A damper assembly for use with the inlet duct of a pollution control system,
- said damper assembly including first and second spaced apart support means,
- a first plurality of spaced apart access openings formed in at least one of said support means, a plurality of elongate vane means extending in a generally parallel relation between said support means and each being in general alignment with one of said openings,
- a plurality of first pivot means each removably mounted adjacent each opening and a releasably supporting one end of each vane means and second plurality of pivot means for releasably supporting the opposite end of each vane means on the other support means for pivotal movement of said vane means between a first position wherein said vane means inter-relate to substantially impede the flow of gas in said duct and a second open position,
- each of the said openings aligned with each vane means being of sufficient size to permit said vane means to be slid therethrough,
- and trolly means for supporting said vane means for axial sliding movement through said openings whereby said vane means may be individually removed and replaced,
- and cover means releasably securable over each of said openings.
