Belt press filter, in particular for dewatering fine coal

摘要

In pneumatic belt press filters, in particular for dewatering fine coal, which are equipped with a filter belt which discontinuously passes through a pressure vessel having sealing apparatuses movable on both sides, the filtrate chamber and chamber for medium to be filtered are arranged in a yoke-like frame, at least one of the two chambers being pressed via mechanical or hydraulic actuators against sealing surfaces of the other chamber in each case. However, belt press filters of this type are very expensive in terms of their construction and complicated. According to the invention, the construction of the belt press filter is considerably simplified by designing the pressure vessel as a horizontal tube (1) having rectangular outlet openings for the filter belt (5). <IMAGE>
