Title: Drum structure for rotary drum filtering apparatus and methods of using same
Inventor: GRACE TODD S
IPC: B01D33/067
Filed: 2006-06-07
Granted: 2011-07-19
Abstract: A drum structure for corrugated type rotary filters has relatively high filtering efficiency and relatively low manufacturing and/or installation costs. More specifically, a corrugated deck section is rigidly connected to a rotary drum structure by means of solid non-apertured divider grids which establish a drain channel. The drain channel is subdivided into respective compartments by means of intermediate solid non-apertured grids which are unconnected to the corrugated deck, but provide subjacent radial support thereto. Drainage slits are provided in the corrugated deck in alignment with each of the compartments. Plug dams are provided in the corrugation spaces between the upper edge of the intermediate grids and the lower corrugated deck surface so as to prevent substantially filtrate flow between individual compartments. Filtrate may thus flow through the drainage slits and into a respective one of the compartments where it can then subsequently be drained transversely and longitudinally into a respective port associated with the drum filter.
