Abstract

A packaged construction filter and dryer machine is claimed which functionally and automatically combines a vacuum band filter with a filtrate expressing unit. The porous band, carrying filter cake from its passage around the partly-immersed vacuum filter drum, moves horizontally into the expressing unit to be squeezed between a porous drainage plate below the band and a fluid-pressurised, impervious membrane above the cake, the machine being programmed so that drum rotates periodically to advance the band only when the expressing unit is inactive and the cake and band are pressed against the drainage plate only when the filter is very convenient, easily installed combination which is very effective in drying sludges etc. prior to incineration.
