Du vacuum belt filter:

1. Ring type rubber discharging belt is used with high tensile strength and long service life

2. Ring type abrasive belt is set between vacuum container and the rubber belt, water is used to airproof and lubricate which can keep stable and higher vacuum degree, good for stable operation state.

3. Rubber belt is supported by air cushion or water to reduce the resistance and is good to prolong service life of the rubber belt.

4. The whole structure adopts module design which can be consolidated freely, convenient for transportation and installation.

5. Vacuum balance automatic discharging tank or steam-liquid separator is set to carry out zero potential difference automatic discharging or high potential difference discharging to satisfy requirements from different working states

6. Air chamber type automatic deviation correction device is set to assure stable running of the filter cloth.

7. The control system uses PLC technology to carry out PID regulation, provide safety guarantee of running and supervision of the procedure.
