Outside filtering surface drum vacuumfilter

Out side-drum vacuum filter is widely usedin ore-processing, metallurgical industry, chemical plant, paper industry andetc, for dewatering floatation concentrates of non ferrous metals (such ascopper, zinc, lead, nickel and etc,) and concentrates of non metal (such assulphur, phosphorus, talcum, fluorite, coal and etc,) and can also be used forseparating liquid and soild in suspensoids which are not easy to be setteddown.

Structure: This kind of equipment is mainlycomposed of drum, trough, distribution head, blender, and transmission device.

Working Principle: During the operation ofthe filter, the slurry is fed into the trough. At this time, the slurry in thetrough remains suspended as the result of the stirring of the blender. When thedisc rotates, due to the vacuum in the vacuum filter, the solid materials aresucked from the slurry to the surface of the excircle of this drum submerged inthe tank containing slurry. 

When the surface of the filter is exposed tovacuum, filter residual formation belt and dewatering belt are always retained.At this time, materials sticking to it begin to be sucked dry. 

When the drumcontinues to rotate, filter residual scraping belt appears. Here the vacuuminside the drum changes into compressed air. It blows down the filter residualand blow off through the filtration hole of filter cloth. To remove the filterresidual on the filtering surface, a kind of special scraper shall beinstalled. Before slurry is reinfused to the surface of the drum, the surfaceof the filter is again affected by vacuum.
