METHOD FOR SEALING A FILTER CHAMBER AND FILTER DEVICE

摘要

The invention relates to a method for sealing a filter chamber of a filter device, comprising a sequence of steps, including moving the recess plate close to the adjacent recess plate for building the pack, and securing the recess plate to the adjacent recess plate, piping a suspension into the filter chamber on a cake side of a filter cloth, letting a solid content of the suspension settle on the filter cloth as a filter cake, and a liquid fraction of the suspension permeate the filter cloth to a filtrate side thereof, and discharging the filtrate out of the filter chamber. The invention further relates to a recess plate for use in a filter device, the recess plate comprising a recess, and a groove encircling the recess, the groove being adapted to receive a sealing ring for sealing a filter chamber.

主权项

1. Method for sealing a filter chamber of a filter device, the filter device having a pack of at least a recess plate and an adjacent recess plate, the recess plate having a first recess and/or the adjacent recess plate having a second recess, the first recess and/or the second recess forming the filter chamber between the recess plate and the adjacent recess plate, the recess plate having a groove encircling the filter chamber, and a sealing ring inserted into the groove, the sealing ring sealing the filter chamber from a gap between the recess plate and the adjacent recess plate, the method comprising a sequence of steps, including
a. moving the recess plate and the adjacent recess plate close together for building the pack, b. securing the recess plate to the adjacent recess plate, c. piping a suspension into the filter chamber on a cake side of a filter cloth, d. letting a solid content of the suspension settle on the filter cloth as a filter cake, and a liquid fraction of the suspension permeate the filter cloth to a filtrate side thereof, and e. discharging the filtrate out of the filter chamber, characterized by moving the and adjacent recess plates into contact, and then forcing the sealing ring out of the groove towards the adjacent recess plate.
