Abstract
The utility model discloses a vacuum belt filter dewatering machine. A filter belt sticks to a rubber belt closely with a corrugated slot, and driven by a motor together with the rubber belt, moving forward along one direction. The corrugated slot of the rubber belt is linked to a vacuum chamber. The rubber belt is supported by two lubricating supporting blocks and is sealed by water. Two supporting blocks and the rubber belt form a vacuum chamber. While working, the rubber belt outside the vacuum chamber is supported by the compressed air, which can greatly reduce the friction. Filter cakes at the outlet are further squeezed for the dehydration, so as to get drier cakes, and economize energy for continuously drying up. After the filter regeneration, filtering nets start re-filtering operation. The filter machine has vacuum filtration, great filtration driving force; the moisture content of filter cakes is low after the mechanical extrusion. The cake thickness can be detected automatically in the process, controlling the belt speed through the filter cake thickness so as to ensure the uniformity of the cake. The requirement for the flexibility of the operation of the filtrate solid is low. The machine can be operated continuously with high degree of automation and good economic benefit.
