Horizontal plate filters

How does a plate filter work?

A plate filter consists of a vertical tank containing a stack of horizontally positioned filter plates. The slurry that is to be filtered is fed into the tank under pressure and passed over the plates where the cake is collected by the filters. The circular plates have radial ribs welded to their undersides. On these rests a coarse-meshed screen covered with a finer-meshed metal screen or filter cloth which retains the cake. The bottom of the plate slopes toward the hollow central shaft, allowing the filtrate to flow freely through the circumferential holes and further down the shaft to the filtrate outlet. The cake collected in the plate stack is thrown against the wall of the tank by centrifugal forces, depending on the model of horizontal plate filter this is done by a rotating or vibrating motion. The cake then falls to the bottom of the tank where it is discharged.

Where can a horizontal filter be used?

Historically, horizontal plate filters have been widely used in the fine chemical process industries, in the production of antibiotics, pesticides or pigments, for example, where the load of impure insoluble substances is low and polishing is required to obtain high product clarity. In recent years, however, they are increasingly seen in heavier industries such as fertilizers or in mining and metalworking where the product is actually the cake and efficient washing and low humidity are required. Plate filters are ideally suited for handling highly flammable, toxic and corrosive substances because they are designed for hazardous environments where high pressure and safe operation are required.
