Filter for the continuous filtration of liquids containing solids in a closed cylindrical vessel

摘要

Filter for the continuous filtration of liquids containing solids or the like in a closed, cylindrical vessel having a pressure drop between the liquid to be filtered and the filtrate, having discs formed from hollow filter sectors at a distance from each other which are arranged vertically on a driven, horizontal hollow shaft, having filter layers on both sides on each filter sector and a cavity provided in between for outlet of the filtrate through the hollow shaft and stationary devices on both sides of each filter disc for taking off and removing the solids or the like from the filter layers forming the filter disc exteriors, each device, to take off and remove the solids or the like from the filter layers, each comprising a closed hollow box completely surrounded by the liquid to be filtered, which box abuts liquid-tightly the associated filter layer and in the contact area has at least one inlet gap covering the entire radius of the filter disc, the pressure-tight filter layers formed by the filter disc exteriors each comprising two planar, pressure-resistant filter plates each having at least one filter sheet and being formed with inner, opposite supports and membrane-like microporous surfaces and the clamped-on take-off vessels extending radially over the filter disc exteriors [lacuna] movable on the inlet side ...
