TC precise vacuum filter combines mechanical and electric machine, ceramic tube with micro-hole and ultrasound to separate solid and liquid depending on vacuum suction and capillary function with high efficiency and energy-saving equipment; They are widely used for mine, metallurgy, chemical industry and environmental protection industry.

Characteristics:
High vacuum degree (0.09~0.098MPa), filter cake has low water content
Solid content of liquid <50ppm, repeated application is available, drainage is lessened.
It can save 90% energy or above in contrast with traditional filter with low consumption and low cost.
Filter cake cleaning process is added to clean proper materials.
It combines PLC, computer and automatic valve control with high automatization and labor force has been lowered.
Close structure, cover less floor area, convenient installation and maintenance
Advanced drainage system fits for any working state.
Working Principle:
Slurry-sucking district: Screen plate which is dipped in the slurry will be formed into one layer of filter cake under capillary function and vacuum pressure, the liquid will enter into distributing valve and drain tan via screen plate.

Cleaning district: Spray the filter cake after coming out of the hopper
Drying District: Filter cake will be dehydrated under high vacuum function
Discharging district: The scraper will discharge the materials automatically under no-vacuum state

Back-cleaning district: Industrial water or filter liquid will be cleaned from inner part to outer part after entering into distributing valve and ceramic board. Clean micro-hole of jam. After one period of application, ceramic board should be cleaned with ultrasonic and acid with low concentration to let the board work with high efficiency.

Screen Board
Latest Inorganic Film Patented Technology in the World from SUNNY Enterprise
1. Framework has high concentration, film has high intensity, excellent resistance to wear, compression and corrosion. White alundum is electrically melted and moulded into grads with 500t hydraulic press and 1430º C whole agglomeration, voltage resistance can reach 8bar.

Control System
Combine computer control or touch screen with PLC control; Inlet, filter, clean, acid prepare all adopt automatic control; Stir and main shaft speed reducer all adopt frequency control, one worker can operate many machinery with high automatization, simple operation and high security and reliability.

Vacuum System
Distributing valve adopts corundum and mirror treatment with good airproofing, wearable performance, simple structure and long service life (patent) and can be easily repaired.
Adopt secondary vacuum system to reach vacuum limit, therefore water content of filter cake is much lower, vacuum type can choose free-fall condition, automatic drainage (patent) and assistant dehydration.

2. High open porosity and productivity; High filtering precision, low vacuum consumption. Fine materials, whole compound, stick without glue, good water permeability, open porosity can reach 92%; Adopt 1800mesh superfine white alundum film-spraying pre-coating technique which has good capillary function and low vacuum consumption.
3. Many methods for regeneration, service life is greatly prolonged. It can be cleaned with organic solvent under high temperature and high voltage with good regenerating effect and long service life.

Cleaning System (Patent)
Regenerated filtrate system adopts precise filter with good environmental protection high energy-saving function.
Adopt water supply system with constant voltage which is safe and reliable.
Ultrasonic and chemical cleaning agent are used to clean the ceramic board to assure high working efficiency.
Automatic acid preparation can lessen labor force and risk.
