摘要： PURPOSE:To provide a titled dehydrator which increases the dehydration efficiency by gravity by providing baffle plates which contact linearly with a filter cloth belt and increasing the exposure area of the filter cloth belt where sludge is formed by raking. CONSTITUTION:The sludge supplied onto a filter cloth belt 1 is carried in an arrow 19 direction and is passed under a rear bracket 29. In this stage, the sludge is distributed in the transverse direction of the belt 1 by baffle plates 33a erected on the surface of the belt 1, and is passed as sludge ridge of ridged shape between the plates 33a.... The free water squeezed and leeched by the raking effect thereof is permeated through the meshes of the belt 1 and is dropped. The sludge layer is again ploughed over by the baffle plates 33b... in succession thereto to expose the belt surface and to squeeze the sludge, whereby the moisture content of the sludge is decreased. The sludge is further crushed with a weir plate 47 and is fed to succeeding squeezing rolls. Thus, the baffle plates and the weir plates are disposed alternately to plough over the sludge many times and to discharge and dorp the free water by the compressive squeezing of the sludge and the exposure of the belt surface at each time, whereby gravity dehydration is progressed with extremely good efficiency.
