Abstract: A belt filter device mounted on a frame carrying an endless conveyor belt has a casing arranged below an upper run of the belt, and application of subatmospheric pressure to interior regions of the casing causes liquid to be withdrawn from material lying on the conveyor belt through drainage holes provided in the belt. The casing is pivotal with respect to the frame between a first, operational position and a second, cleaning position, and a separating means shifts the casing away from a cover or support means simultaneously with movement of the casing from its operational position toward its position for cleaning.

Abstract: The invention is relating to a method of removing fluid from a mixture of fluid and solid substance, in which the mixture is guided with the aid of a conveyor belt along the outer circumference of a drum which is surrounded at least over part of its circumference by the conveyor belt, whereby the conveyor belt is positively driven in order to obtain the intended displacement thereof, while the drum is braked as well as to a device for carrying out the method of aforementioned comprising a drum and a belt extending along part of the drum, the relative dispositions of the drum and the belt being such that the mixture can be carried along between the belt and the drum, which are each or both previous to fluid, whereby the device comprises furthermore means for driving the belt and means for braking the drum.
