Chamber Filter-Presses

Chamber filter-presses are the modern equipment for effective separation of solid and liquid phases of medium- and poor-pressing suspensions in chemical, mining, coal, ceramic, food (sugar) and other industries.

In the sugar industry the use of chamber filter-press is the most progressive method of withdrawal of the filter cake.

Chamber filter-press are also used for direct filtration of I-th carbonation juice.

The main operation performed by chamber filter-press:

• filtration;
flushing of sediment;
drying the sludge;
scavenging collector;
discharge of sediment.

Replacement of vacuum-filters to filter-presses will allow:

reduce the loss of sugar in the sediment to the level of 0,03% by weight of beets/cane;
reduce the dilution of juice;
excluded from the technological scheme of vacuum condensing unit of vacuum filters, which consumes a large amount of chilled

exclude the vacuum pumps;
reduce consumption of electricity;
obtain a cake with a moisture content of not more than 30%, which makes it possible to remove it mechanically;

use a special filter cloth for 2 production seasons.

As an example it is represented a chamber filter-press

The advantages of this filter are:
full automation of the process of filtering based on microprocessor;
simple to operate and maintain automation;
hydraulic membrane wringing of sediment (not required compressor and receiver as in the case of a pneumatic wringing);
the washing device for regeneration of filtering cloth directly on the filter;
effective discharge device: filter discharge time reduced to 7 minutes;
increased to 50 mm depth of the chamber, which increases productivity by 10-12%;
you can adjust the speed of plates movement;
in addition filters can be equipped with "a light curtain»;
electronics of Siemens;
low price.

Filtration equipment is manufactured in strict accordance with national and international standards.

Durability of metal parts and components filter in an alkaline medium saturated juice has been successfully tested on ten Russian sugar factories.
