Vacuum Ceramic Disc Filter Mineral Tailings Dewatering /
A vacuum ceramic filter is designed to separate liquids from solids for dewatering
purposes. The device consists of a rotator, slurry tank, ceramic
filter plate, distributor, discharge scraper, cleaning device,
frame, agitating device, pipe system, vacuum system, automatic acid
dosing system, automatic lubricating system, valve and discharge
chute. The operation and construction principle of vacuum ceramic
filter resemble those of a conventional disc filter, but the filter
medium is replaced by a finely porous ceramic disc. The disc
material is inert, has a long operational life and is resistant to
almost all chemicals. Performance can be optimized by taking into
account all those factors which affect the overall efficiency of
the separation process. Some of the variables affecting the
performance of a vacuum ceramic filter include the solid
concentration, speed rotation of the disc, slurry level in the feed
basin, temperature of the feed slurry, and the pressure during
dewatering stages and filter cake formation.
Slime Absorbing Zone: Filter plate immersed in the slime while in
operation produces a surface absorption of filter cake, with the
action of capillarity and integrated with vacuum pressure. Filtrate
enters distributing valve and drainage tank through filter plate．
Leaching Zone: Filter cake coming out from slime hopper receives
Drying Zone: Continuous dehydration for filter cake is conducted
with the action of high vacuum force．
Discharging Zone:Scraper will automaticly discharge materials once
entering the vacuum-free condition．
Back Flushing:Service water or filtrate enters the ceramic plate
through distributing valve and cleaning the blocked minihole
entoectad．Cleaning with ultrasonic and low density acid after
ceramic plate is used for one period to maintain the efficient
service life of ceramic plate．
( 1 ) Energy efficient : large capacity , energy-saving effect is
obvious. Handling capacity > 1100kg/m2 h, electricity
<0.5kWh/th, compared with the conventional disc filter outside
the filter , over 80% energy saving .
( 2 ) Automatic control : Performance Series models using program
control, automatic feeding, automatic cleaning , reduce labor
intensity , can reduce the number of operations personnel .
( 3 ) improve the automatic protection features: automatic fault
alarm system , fault -screen display, high and low level alarm
display, and automatically exclude or shut down manually.
( 4) The structure of a solid , durable : The machine adopts
computer optimization design, rational structure, reliable ,
maintenance-free design main transmission components , reducing
downtime rate , tank mixing system made of stainless steel body
structure to ensure its service life of up to 10 more years .
( 5 ) improve product quality, reduce transportation costs: Due
concentrate low water filtration treatment can greatly improve the
market competitiveness of products and reduce transportation costs
during transport and loss.
( 6 ) environmental effect is obvious : Because of the clear
filtrate , repeated use , reduce emissions and comply with
environmental clean production of the current trend.
