Abstract
The invention is an apparatus for cleaning accumulations of dust and waste matter from filter media in industrial installations. The dust and waste matter is removed from the filter media with nozzles that move across the filter media in reciprocatory paths. The apparatus of this invention moves the nozzles in a continuous motion during normal operation without having to successivley stop and reverse at the end each path as in the prior art filter cleaning devices.
Claims11
Apparatus for cleaning filter media comprising nozzles that travel across one surface of filter media in a reciprocatory path between opposed ends of the filter media to remove accumulations of dust and waste matter from the filter media, said apparatus having a manifold carriage operatively connected to the nozzles, a chain hoist mechanism, the chain hoist mechanism having top and bottom sprockets at each end of the manifold carriage and drive chains extending around the top and bottom sprockets, wherein the improvement comprises means for continuously reciprocating the nozzles between the opposed ends of the filter media without stopping to reverse direction during normal operation, said means comprising:
- (a) a car attached to each end of the manifold carriage,
- (b) a pivot arm for each car,
- (c) a chain attachment for connecting each pivot car to a drive chain,
- (d) means connecting the chain attachments to the drive chains,
- (d) means connecting the chain attachments to first ends of respective pivot arms, and
- (e) means pivotally connecting second ends of the pivot arms to their respective cars,
- whereby the chain attachments carry the first ends of the pivot arms around the sprockets while the means pivotally connecting the second ends of the pivot arms to their respective cars rotate the second ends of the pivot arms relative to their respective cars while the first ends of the pivot arms are carried around the sprockets, and whereby the pivot arms move the cars and manifold carriage in reciprocatory paths and the nozzles continuously reciprocate between the opposed ends of the filter media without stopping to reverse direction during normal operation.
Apparatus for cleaning filter media comprising nozzles that travel across one surface of filter media in a reciprocatory path between opposed ends of the filter media to remove accumulations of dust and waste matter from the filter media, said apparatus having a manifold carriage operatively connected to the nozzles, a chain hoist mechanism, the chain hoist mechanism having top and bottom sprockets at each end of the manifold carriage and drive chains extending around the top and bottom sprockets, wherein the improvement comprises means for continuously reciprocating the nozzles between the opposed ends of the filter media without stopping to reverse direction during normal operation, said means comprising:
- (a) a car attached to each end of the manifold carriage,
- (b) a pair of guide tracks at each side of the manifold carriage,
- (c) wheels on the cars for engagement with the guide tracks,
- (i) the wheels including opposed flanges that extend along the sides of the tracks,
- (d) a pivot arm for each car,
- (e) a chain attachment for connecting each pivot car to a drive chain,
- (f) means connecting the chain attachments to the drive chains,
- (g) means connecting the chain attachments to first ends of respective pivot arms, and
- (h) means pivotally connecting second ends of the pivot arms to their respective cars,
- whereby the chain attachments carry the first ends of the pivot arms around the sprockets while the means pivotally connecting the second ends of the pivot arms to their respective cars rotate the second ends of the pivot arms relative to their respective cars while the first ends of the pivot arms are carried around the sprockets, and whereby the pivot arms move the cars and manifold carriage in reciprocatory paths and the nozzles continuously reciprocate between the opposed ends of the filter media without stopping to reverse direction during normal operation the drive chains.
Apparatus for cleaning filter media comprising nozzles that travel across one surface of filter media in a reciprocatory path between opposed ends of the filter media to remove accumulations of dust and waste matter from the filter media, said apparatus further comprising means for continuously reciprocating the nozzles between the opposed ends of the filter media without stopping to reverse direction during normal operation.
