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.

Working principle:
Horizontal rubber belt vacuum filter with filters as the filter media, is full use of gravity and vacuum suction material to achieve effective separation of the solid-liquid separation equipment. Ring of rubber belt vacuum chamber as a whole. Drag the ring belt from motor runs continuously, filter cloth dressing on the belt and run synchronously, tapes and vacuum skid pad ring contact friction belt and the formation of the water seal. Slurryby the distributor of evenly distributed on the filter cloth. when the vacuum chamber connected to the vacuum system, forming vacuum area on the tape, landfill leachate wearing summary and transverse grooves on the belt filter cloth by a small hole into the vacuum chanber, solid particles are withheld on the filter cake formation. Liquid discharge separator into the vacuum chamber, along with the rubber band to move, cake that has been formed in order to enter the filter cake washed area and dry area, finally separating filter cloth and adhesive tape, filter cake is discharge at the unloading roller. Discharged after washing, the cloth filter regeneration of filter cake, and then through a set of back-up roll and again after correcting device into teh filter area, began to enter new filter cycle.
