The filter press machine is a mechanical solid-liquid separation unit which is used in the field of pressure filtration of suspensions (heterogeneous mixture of a liquid and finely divided solids). Its origin lies in southwestern China. As early as 1600 BC, camellia oil was extracted from the camellia plant using a wooden filter press architecture.

The filter press separates the liquids from the solids using pressure filtration. Each filter press is designed based on the volume and type of sludge slurry that needs to be dewatered. The operating principle of filter press is that the liquid sludge is pumped between the filter plates so that solids are distributed evenly during the fill cycle.

Rotary Vacuum Drum Filter Designs Include: Scraper Discharge is the most common drum filter discharge. After dewatering, the cake is removed from the filter cloth by a scraper blade just prior to the re-submergence of the drum. The scraper serves mainly as a deflector to direct the cake, dislodged by an air blowback, into the discharge chute.

The filter disc is driven by a motor through a speed reducer and an open gear transmission. The filter disc rotates clockwise. The slurry in the filter chamber in the adsorption zone uses a vacuum pump to create a pressure difference on both sides of the filter medium. After the cake, the stirrer is rotated to prevent solid precipitation.

Drying zone: continuous dewatering for the filter cake is conducted with the action of the high vacuum force. Discharging zone: the scraper will automatically discharge materials once entering the vacuum-free condition. Back Flushing: the service water or filtrate enters the ceramic plate through distributing valve and cleaning the blocked manhole.

A continuous pressure filter may be defined as a filter that operates when the pressure drops below than 1 bar and its operation does not interrupts the discharge of cake. The advantage of any continuous filter is the absence of reduction in down-times, which means gain in capacity. Bearing in mind the effects of compressibility of cakes, the ...

String Discharge: best applies to thin cakes and materials that are unstable and if disturbed too much will change from a solid to a liquid. Most generally applied in the starch and pharmaceutical industries, it is a system of endless strings or wires spaced about 0.5 inches apart that pass around the filter drum but are separated tangentially from the drum at the point of cake discharge.
