Pump and submersible solids processing arrangement

摘要

A pump and submersible solids processing arrangement includes a pump, having a suction inlet and discharge, and a submersible solids processing arrangement positioned in fluid communication with the suction inlet of the pump and being structured to macerate larger solids and matter that is entrained in a fluid to thereby reduce the size of the solids prior to entry of the fluid and solids into the inlet of the pump, the arrangement further including macerating members the speed and arrangement of which are selectively determinable or adjustable, and the arrangement further comprising an agitator arrangement for directing solids into the submersible solids processing arrangement.

1. A submersible apparatus for processing and pumping fluid-entrained solids, comprising:
a pump having a casing, a suction inlet, a discharge outlet and an impeller positioned within the casing, the impeller having a rotational axis; a drive assembly connected to the impeller for imparting rotation to the impeller; a support frame having a first platform to which the suction inlet of the pump is secured, the first platform having an opening formed therethrough to which the suction inlet of the pump is aligned for receiving fluid through the opening in the first platform, and the support frame having a second platform positioned parallel to the first platform and spaced apart from the first platform, the support frame including spacers connected between the first platform and the second platform to maintain a space therebetween; a submersible solids processing arrangement positioned between the first platform and second platform of the support frame, the solids processing arrangement further comprising a plurality of rotatable macerating members that are journalled between the first platform and second platform, each of the macerating members being structured with macerating elements that extend outwardly from an outer surface of each macerating member, whereby the macerating members are arranged to encircle the opening of the first platform of the support frame and are arranged so that the macerating elements mesh with macerating elements of adjacently positioned macerating members to define a pathway for entry of fluid and solids into a flow direction prior to entering into the suction inlet of the pump.
