belt filter press / automatic / for sludge treatment / high-pressure
for sludge treatment, high-pressure
The high pressure belt press for sludge is recommended when it is necessary to obtain a strong reduction of the water content in sludge. Generally it is installed downstream the sludge treatment lines and consists of a frame in normal profile, a sludge load hopper, storage and drain tanks for the filtered water, two joined belts through which the sludge to be dewatered passes, a roller assembly used to drain and press the sludge, belt puller, belt centring and transmission rollers, a washing system with nozzles for each belt and two sturdy planetary gear motors. The roller assembly comprises one first big diameter drainage roller, one second drainage roller, one low pressure roller, one medium pressure roller, nine high pressure rollers, two transmission rollers, two belt pullers, two belt centring rollers and four return rollers. The sludge goes in touch with the belt in the higher part of the belt press, goes through a long section where the water drips by gravity and successively falls on the second belt and goes on flowing into a wedge which facilitates the very delicate removal of the water from the sludge.
