Abstract
An electrode rapping arrangement for cleaning the collecting electrodes of a pair of serially aligned electrode assemblies in an electrostatic precipitator. The rapping arrangement includes a shaft extending horizontally across the interior of the precipitator between the electrode assemblies, and a crank mounted on the shaft between each of the opposing serially aligned electrodes of the electrode assemblies. An articulated linkage is pivotally secured to each of the cranks so as to swing a hammer mounted on the end of the linkage into an associated electrode on one of the electrode assemblies when the shaft is rotated in one direction and into an opposing electrode on the other electrode assembly when the shaft is rotated in the opposite direction.
Claims9
In an electrostatic precipitator having a flow-through housing and a pair of spaced opposing electrode assemblies with each assembly including a plurality of electrodes and an anvil connected with each of the electrodes aligned with anvils of the opposing electrode assembly, the improvement comprising an electrode rapping arrangement including:
- a rotatably supported shaft extending horizontally across the interior of the housing between the opposing electrode assemblies equidistant from each of the assemblies;
- drive means for rotating said shaft in either direction;
- a crank mounted on the shaft aligned in a plane with each of the anvils;
- said crank having an attachment portion and an outwardly opening hook portion;
- an articulated linkage including a first arm having one end pivotally secured to said attachment portion and a second arm having one end pivotally secured to the other end of said first arm;
- a hammer affixed to the other end of said second arm;
- and
- said first and second arms defining lengths whereby rotation of the shaft in either direction causes the crank to draw the first arm into a position overlying the shaft and continued rotation of the shaft causes the first arm to lift the second arm in a fashion guiding the hammer into the hook portion of the crank which releases the hammer upon continued rotation of the shaft to allow the hammer to swing downwardly on the linkage into the anvil on one of the opposing electrode assemblies when the shaft is rotated in one direction and the anvil on the other opposing electrode when the shaft is rotated in the other direction.
