Ceramic filters

CDF series ceramic vacuum filter is a new model high-effect, saving-energy filtration equipment, which is gathering the machinery-power minihole ceramic ultrasonic technology into one. Depending on vacuum absorbing and capillary effect to come true the separation of liquid and solid. Apply to industry such as mine, metallurgy, chemical industry, environmental protection broadly.

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 automatically 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.

Main parts: ceramic plate, main machine, gas and water mixing constent pressure back washing system, control system.

  

  • Microvac (vacuum degree-0.09—0.098MPa), low moisture of cake.

  • Solid content of filtrate<50ppm, which can be recycle use in the system.

  • Energy saving can reach 90%, low energy consume, low operation cost.

  • Filter cake cleaning system is added, which is fit for the material needs to be washed.

  • PLC and computer integrate with automatic valve control, high degree of automation reduces labor intensity.

  • Compact structure requires a smaller floor space and offers convenient maintenance.

  • Advanced drainage system ensures application in any operating conditions.

 

Filter plate (patent)

Originated from the newest inorganic membrane patent technology of Sunny company.

  1. Strength of membrane layer, high density of frame.

  2. More opening role and higher capacity, reduces the loss of vacuum.

  3. More methods of reused, extend the service life.

Control system

Computer control system or touch screen combining with PLC control system is adopted, accomplish automatic control for feeding, filtration, cleaning and sharing acid. Variable frequency control is taken for agitator and main shaft speed reducer. Single operator for multi-unit can be practiced with high automation, simple and convenient operation, all are safety and reliability.

 

 

 

Constant pressure backwashing system with air and water mixture

  1. Adopts backwashing with air and water mixture, which saved the water more than 50%, meanwhile improved the concentration of materials and increased the production more than 10%.

  2. Adopts constant pressure backwashing, which makes sure the pressure stabilization of wash line and prolongs the using life of ceramic life.

  3. Adopts constant pressure backwashing, which improved service efficiency of centrifugal pump and reduced energy consumption.

  4. This washing system has the advantages of energy-saving, environment-protection, low failure rate, and easy maintenance.

 

 

 

Scope of Application
