■ Introduction

Ceramic filter is the world 's most advanced solid-liquid separation technology , with its energy saving, clean and green , you can re-use of resources and other advantages , in various fields of national economy increasingly widely used. Ceramic filter is a good example of successful application of ceramic filtration technology , large-scale promotion in the country in recent years has produced good economic and social benefits. The early 1980s , Outokumpu company successfully developed as a filter medium ceramic filter plates , ceramic filter plate pore size is typically 1 - 5 microns ( the most commonly used is 1.5 - 2.0 microns ) , so microporous capillary action can produce a strong , the ceramic filter to work under the action of the vacuum pump , through the porous liquid-only become filtrate , which is solid and gas -barrier becomes cake filtration plate surface to achieve a solid-liquid separation.

Birth of a new filter media for the development of solid-liquid separation technique has great significance , to produce a ceramic filter plate capillary action and has excellent mechanical properties, the ceramic filter cloth and the other in the filter compared to the filter medium having a plurality of advantages, is between this ceramic filter has been widely used . Ceramic filter can be used in non-ferrous metal mine dewatering , coal , chemicals, pesticides, pharmaceuticals, and other industries , wide range of applications .

Advantages:
( 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.

■ Working Principle

Working Principle:
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 spray washing.

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.
