ABSTRACT:
A quick release apex apparatus for a cyclone includes a semirigid cast urethane, neoprene or rubber apex with an integral splash skirt and an upper annular flange for clamping the apex to the bottom flange of a cone of the cyclone. A quick release split ring clamp has a first section bolted to the flange of the cone and a second section pivotally connected to the first section. A single worker can change a worn apex of even a large cyclone by using one hand to hold the apex in its position and the other hand to release the second section of the quick release clamp and swing it away from the apex flange. The worker then removes the worn apex, sets it aside, lifts a replacement unit into alignment with the cone, swings the second section of the quick release clamp closed and locks it. An outer portion of the apex assembly is ribbed. An adjustable clamp band is disposed about the ribs, allowing gradual tightening of the apex to compensate for orifice wear. A blow-through hole extending part way into the wall of the apex allows a small amount of leakage when the apex needs replacement. In one embodiment of the invention, a replacement apex has opposed straight support flanges that are inserted into a pair of opposed receiving tracks attached to the lower flange of the cone to allow lateral removal and replacement of an apex while the cyclone is operating.
