Disc vacuum filter
Detailed introduction to Vacuum DiscFilter:
Vacuum Ceramic Disc Filter is new typesolid-liquid separation equipment featuring high-efficiency and energy-saving.Shengnuo Group successfully developed PC series VCF In 1998 with exclusivepatented intellectual rights after years of R&D. The PC series VCFs havenow been successfully adopted in the filtration process of wide variety ofminerals such as Iron ores, Gold, Copper, Copper Sulfide, Nickel, Zinc, Lead, Molybdenum,Phosphorus, Sulfur, Quartz Sand, and Fluorite etc.
The shape and working principles aresimilar to those of disc filters. Under the effects of pressure difference,when the slurry penetrates filter media, particles are blocked at the surfaceof filter media and filter cake is formed while liquid goes through the mediaand drained away so as to separate solid from liquid. The major differencebetween VCF and disc filter is filter media-ceramic filter plates. There aremicro pores that create capillary effect. Capillary force override pressurecreated by vacuum system and fills micro pores with liquid and no airpenetration possible under whatever circumstances. Because no air allowed topass through the plates, energy consumption is low and vacuum is high duringsolid-liquid separation process.
The ceramic filter consists of CeramicFilter Plates, Rotator, Slurry Tank, Scrapers, Distributor, Agitating Device,Back-Washing (including Ultrasonic & Acid cleaning), Frame, Vacuum System,Pipe System, Filtrate Discharge System, Discharge Chute, Valve And PLCAutomatic Control System (can be built into remote control system). The systemcan be customized by adding cake washing system if required.
VCF has short downtime and improvesproductivity and operation rate. Because no needs of any filter cloth, the VCFcan maintain high degree of vacuum and low moisture of filter cake. It is alsofeatured by energy efficient. Compared with traditional disc filters with 45m2,the VCF with the same filter area saves over 85% of power energy. In the meantime, because of the tiny size of micro pore, fine particles are block so as toincrease metal recovery rate and help improve quality and transparency offiltrate (normally 21mg/l of solid content). Filtrate can be recycled. Ingeneral, VCF is a kind of environmentally friendly, highly efficient, andenergy-saving solid-liquid separation equipment.
