This system utilizes a fully enclosed pressure vessel design for high‑efficiency solid‑liquid separation. The filter unit is housed within a sealed pressure chamber, with a belt conveyor positioned beneath the filter discharge chute and a discharge device installed at the head end for automated cake removal.

During operation, the feed slurry is continuously pumped into the filter tank. Simultaneously, compressed air is introduced into the pressure chamber to establish a controlled pressurized environment. As the filter discs rotate, a pressure differential is created between the filter disc and the atmospheric‑vented filtrate separator via the distribution valve. This differential pressure forces the liquid phase through the filter media immersed in the slurry, while the solid particles are retained on the media surface, progressively forming a filter cake.

As the discs continue to rotate, the cake passes through a drying zone to reduce residual moisture before reaching the discharge zone, where it is efficiently stripped from the media. The discharged cake drops onto the conveyor and is transferred to the lower hopper of the discharge device. The system runs continuously; once a predetermined volume of cake has accumulated, the discharge device cycles intermittently to discharge the cake from the system.

The entire sequence—filtration, drying, cake discharge, and material handling—is fully automated, requiring no manual intervention. This ensures reliable, continuous operation with minimal labor and reduced operational risk.
