Abstract:
A vacuum belt filter including a belt with a plurality of vacuum boxes, filter means being arranged to the vacuum boxes, drive means for moving the belt, and a suction station for creating an underpressure to the vacuum boxes at the suction station. In order to enable liquid-solid separation at low energy costs and long service interval of the vacuum belt filter, the filter means is in the form of a capillary filter, each vacuum box being provided with such a filter and each vacuum box being provided with an outlet having a check valve enabling a fluid flow from the inside space of the vacuum box to the outside of the vacuum box for creating an underpressure in the vacuum box when the suction station is connected to the vacuum box.

Claim (Index 78):
The vacuum box according to  claim 77 , wherein the inlet comprises a check valve comprising a mechanical actuator for closing a blocking member of the check valve, the mechanical actuator keeping the blocking member of the check valve and the check valve in a closed position when a pressure acting from the outside of the vacuum box against the blocking member and against a force of the mechanical actuator is smaller than the sum of the force of the mechanical actuator and the pressure acting from the inside of the vacuum box on the blocking member; and the check valve opening when the pressure acting from the outside of the vacuum box against the blocking member and against the mechanical actuator is bigger than the sum of the force of the mechanical actuator and the pressure acting from the inside of the vacuum box on the blocking member.
