摘要

The present invention relates to vacuum belt filter comprising a belt (1) with a plurality of vacuum boxes (2), filter means being arranged to the vacuum boxes, drive means (4) for moving the belt (1), and a suction station (5) for creating an underpressure to the vacuum boxes (2) at the suction station (5). In order to enable liquid-solid sepa- ration at low energy costs and long service interval of the vacuum belt filter, the filter means is in the form of a capil- lary filter, each vacuum box (2) being provided with such a filter and each vacuum box being provided with an outlet (8) having a check valve enabling a fluid flow from the in- side space of the vacuum box to the outside of the vacu- um box for creating an underpressure in the vacuum box when the suction station (5) is connected to the vacuum box, said 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 (5). The inven- tion relates also to a filter element, a vacuum box (2) and methods for servicing a vacuum belt filter and a method for liquid-solid separation by means of a belt filter.
