Horizontal vacuum belt filter machine comprises frame with spaced apart drums journaled to frame and endless belt structure mounted on drums. Endless belt structure has upper horizontal path of travel and comprises multiple longitudinally oriented endless belt segments arranged in side-by-side fashion with overlapping joint between adjacent edge portions of belt segments. Drums include first arrangement comprising multiple drums equal in number to multiple endless belt segments with each of multiple drums associated with separate one of belt segments. Drums further include second arrangement comprising single drum for multiple belt segments. Endless filter medium covers endless belt structure in area of upper horizontal path of belt travel, and suction device in area of upper horizontal path of belt travel cooperates with endless belt structure and filter medium for withdrawing liquid from slurry-like materials deposited upon filter medium.
In a horizontal vacuum belt filter machine of the type comprising a frame, spaced apart drum means journaled to the frame at opposite ends thereof, endless belt means mounted on the drum means having an upper horizontal path of travel and comprising a plurality of separate longitudinally aligned endless belt segments, an endless filter medium supported upon the endless belt means in the area of the upper horizontal path of travel, and suction means beneath the upper horizontal path of travel cooperating with the endless belt means and the filter medium for withdrawing liquid from slurry-like material deposited upon the filter medium, the improvement being characterized by the spaced apart drum means at one end of the frame including a plurality of independent drums having the plurality of endless belt segments mounted thereon, each independent drum being jounaled upon an axle for rotation independently of the others, and means for adjusting the longitudinal spacing of the axles relative to each other.
