TFI Filtration (India) Pvt. Ltd provides Linear Continuous Sludge Recovery filter. It has deep, trough shaped, vacuum trays. Thesetrays form the support for the filter cloth, which is in the form of an endless belt. The belt moves thorough the filter in short steps during which period the vacuum is momentarily switched off.
To do this vacuum valve is closed, vent valve is opened and the discharge roller moves forward drawing the cloth with it. In the outboard position the valves reverse thus reapplying vacuum and the discharge roller retracts slowly discharging the cake. The vacuum trays are deep troughs in which the cloth lies and cakes up to 25/30 mm thick can be accommodated without risk of spillage. The non-return roller locks the return cloth. The length of cloth which is being displaced comes from the tensioning system, and floating roller is moved. As soon as the discharge roller is free, and the floating roller moves from position. The filter cloth is being washed in a washing box; flat jet sprays wash the cloth from either face or back. The cloth tracking consisting of two opposing sets of pinch rollers keep the filter cloth on an exact course.
