The belt filter press is a continuous-feed dewatering device that applies chemical conditioning, gravity draining, and mechanical pressure to dewater sludge. Rubber belt type vacuum filter takes filter bag as filter medium, adopt material gravity and vacuum suction to separate solid and liquid materials.
It is adopted ring rubber belt as a vacuum chamber. The vacuum chamber continuously running by motor, filter cloth are layup to the rubber belt and running along with the belt, the rubber belt with friction belt create a water-tight seal. Slurry are distributed on filter cloth by distributing device When the vacuum chamber is switched on vacuum system, it will create a vacuum area on rubber belt, Filtrate liquor pass through filter cloth by horizontal grooves on rubber belt, then get together and go into the vacuum chamber by micro pore, Solid powder are holding on filter cloth, then create a filter cake.
