Product Details


Ceramic filter is the world’s most advanced solid-liquid separation technology; with its energy saving, clean, and green, you can reuse resources and other advantages in various fields of a national economy increasingly widely used. Ceramic filter is a good example of the successful application of ceramic filtration technology; large-scale promotion in the country in recent years has produced good economic and social benefits. In the early 1980s, the Outokumpu company successfully developed 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 ceramic filter to work under the action of vacuum pump through the porous liquid-only filtrate, which is solid and gas -barrier becomes cake filtration plate surface to achieve solid-liquid separation.

The birth of a new filter media for the development of the solid-liquid separation technique has great significance in producing 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 have a plurality of advantages, is between this ceramic filter has been widely used. Ceramic filters can be used in non-ferrous metal mine dewatering, coal, chemicals, pesticides, pharmaceuticals, and other industries, with a wide range of applications.

( 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, and automatic cleaning reduce labor intensity and 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 Machine adopts computer optimization design, rational structure, reliable, maintenance-free design main transmission components, reducing downtime rate, and tank mixing system made ​​of stainless steel body structure to ensure its service life of up to 10 more years.
( 5 ) Improve product quality and reduce transportation costs: Concentrating 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, reduced emissions, and compliance with environmentally clean production of the current trend.

 Working Principle:

Slime Absorbing Zone: The 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 the distributing valve and drainage tank through the 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: The scraper will automatically discharge materials once it enter the vacuum-free condition.

Back Flushing: Service water or filtrate enters the ceramic plate through the distributing valve and cleans the blocked mini hole entreated. Cleaning with ultrasonic and low-density acid after the ceramic plate is used for one period to maintain the efficient service life of the ceramic plate.
