VACUUM CAMERA, BELT FILTER, METHODS OF MAINTENANCE OF TAPE VACUUM FILTER, METHOD OF SEPARATION OF SUSPENSION TO LIQUID AND SOLID PHASES AND FILTER ELEMENT

摘要

This invention relates to a belt vacuum filter comprising a belt (1) with vacuum chambers (2) arranged one behind the other, filtering means located in vacuum chambers, driving means (4) for moving the belt (1), and a station (5 a) suction designed to create a vacuum for vacuum chambers (2) at the specified station. To ensure separation into liquid and solid phases at low energy consumption and a long interval between maintenance cycles of a belt vacuum filter, the filtering device is made in the form of a capillary filter, each vacuum chamber (2) containing this filter and made with an outlet (8) having a reverse a valve providing the flow of fluid from the internal space of the vacuum chamber to the outside of the specified chamber to create a vacuum in this chamber when the suction station (5) is connected to a vacuum chamber, while a non-return valve prevents the flow of fluid through this valve into the interior of the vacuum chamber when the vacuum chamber leaves the suction station (5). In addition, the invention relates to a filter element, a vacuum chamber (2) and methods of maintenance of a vacuum belt filter, as well as a method for separating the liquid and solid phases by means of a belt filter.
