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 89):
A method for servicing a vacuum belt filter comprising a belt with a plurality of vacuum boxes arranged one after another, filter means being arranged to the vacuum boxes, each vacuum box defining an inside space for receiving a filtrate, the vacuum belt filter further comprising drive means for moving the belt, and a suction station comprising suction means connectable to outlets of the vacuum boxes for creating in relation to a surrounding pressure an underpressure to the vacuum boxes at the suction station, wherein the vacuum boxes each comprise a capillary filter, the outlet of each vacuum box being provided with a check valve enabling a fluid flow from the inside space of the vacuum box to the outside of the vacuum box for creating and maintaining an underpressure in the vacuum box when the suction station is connected to the outlet of the vacuum box, the check valve preventing a fluid flow through the check valve to the inside space of the vacuum box when the vacuum box leaves the suction station thereby maintaining the vacuum box under underpressure in relation to the surrounding pressure when the vacuum box becomes outside influence of the suction station, the step of servicing comprising:\n detaching a worn or broken capillary filter, to be replaced, from the belt and replacing it with a new capillary filter.
