Abstract
A panel sector, for a disc filter for separation of liquids from a suspension, includes front and back filter panel assemblies, a sector assembly for mounting the front and back filter panel assemblies, and a top cap for retaining the filter panel assemblies within the sector assembly. Each of the filter panel assemblies includes a frame and a filter material clamped by the frame. The sector assembly includes an outer end plate, an inner core mounting plate subassembly for mounting the panel sector to the disc filter core, first and second side channel subassemblies, at least one structural member extending radially between the core mounting plate subassembly and the outer end plate, and at least one support member extending laterally between the first and second side channel subassemblies. The core mounting plate subassembly and each of the side channel subassemblies have front and back channels for receiving portions of the frame. The top cap first and second end portions are removably mountable to the outer end plate of a one of the sector assemblies and the outer end plate of an adjacent sector assembly, respectively.
