Abstract
A capillary dewatering apparatus, including a framework with a plurality of apertures, and a flexible member disposed around an exterior surface of the framework, in which an inner surface of the flexible member is in contact with at least a portion of the exterior surface of the framework and in which the flexible member and the framework are not bonded. Also disclosed is a capillary dewatering process using the corresponding apparatus.
Claims25
A dewatering apparatus comprising:
- a framework comprising a plurality of apertures;
- and
- a flexible member disposed around an exterior surface of the framework, wherein an inner surface of the flexible member is in contact with at least a portion of the exterior surface of the framework;
- wherein the flexible member and the framework are not bonded.
1 more element
A capillary dewatering process comprising:
- moving a wet web on a top side of a first belt, the first belt further comprising a bottom side;
- contacting the wet web with a top side of a flexible member, such that liquid flows from the wet web through a thickness of the flexible member;
- and
- contacting an exterior surface of a framework with a bottom side of the flexible member, such that the liquid flows from the flexible member to an interior portion of the framework;
- wherein the flexible member is porous;
- wherein the framework comprises a plurality of apertures;
- and
- wherein the flexible member is configured to move independently of the framework.
5 more elements
A dewatering apparatus comprising:
- a rigid framework comprising a plurality of apertures;
- a porous flexible member disposed such that an inner surface of the pourous flexible member is in contact with an exterior surface of the rigid framework;
- wherein a porosity of the porous flexible member is less than a porosity of the apertures in the rigid framework.
