The slurry enters from above the equipment. Horizontal settlement, the slurry under the action of gravity solid layer from coarse to fine, to achieve the ideal filtration performance, and then under the action of vacuum to form a filter cake. And no other power is required to discharge the filtrate.

The dissolved material is cleaned from the porous structure of the cake. The horizontal cake is easy to be evenly and completely wetted in the washing area. During the step suction process, the porous structure is improved because the cake is slightly compressed, which makes infiltration washing extremely efficient. Countercurrent washing can be performed to save the amount of washing water.

In addition to vacuum dehydration, other drying systems are available: hot air or steam can be used to achieve the desired drying effect. If necessary, it can also be equipped with compressed air purging device, high temperature, microwave, mechanical extrusion device.

The cake is discharged from the discharge roll by a scraper. After unloading the cake, the filter cloth goes into the cleaning bucket, the front and back of the filter cloth are washed by high pressure, and the filter cloth is sucked dry if necessary. To improve the service life of the filter cloth and high filtration performance.
