Design Details
Our PBF series of continuous horizontal belt filter uses a vacuum to clean and dehydrate the slurry. We use a filter cloth as the filter medium, and the vacuum chamber is formed using a filter belt supported by a mobile disc. Solid/liquid materials are horizontally distributed along the filter medium, and gravity or vacuum suction is used to perform separation. The feeding, vacuum dehydration, cake washing, slag removal and filter cloth cleaning process are all performed simultaneously, giving the filter its high dehydration ability and excellent filtration effect.
(1) Vacuum process
At the beginning of the filtration process, the slurry is evenly distributed on the filter belt. The filter disk and the filter belt move forward simultaneously, and the vacuum suction is performed on the slurry until the vacuum disk leaves the metal sensing device and releases the vacuum.
(2) Discharging process
The filter belt machine continues to move at the same speed. When the vacuum disk hits the contact limit device, the vacuum switching valve is actuated, and the filter disk immediately releases the vacuum. The vacuum filter disk then returns after 0.5 seconds. The cylinder then quickly returns to its original position as the filter disk returns. This cycle of vacuum filtration process is performed repeatedly until filtration is complete.
(3) Washing, blotting, and slagging process
After the vacuum filter process, to better remove the moisture from the filter cake, countercurrent washing is performed several times. This reduces the mother liquor content in the filter cake to as little as 0.1%.
After washing, the filter cake is sucked through the suction drying area. The content of the filter cake varies according to different materials. Then, the washed and dried filter cake is removed by its change of curvature at the head wheel and the stripping device removes the filter cake.
(4) Filter cloth cleaning
A high-pressure flushing device is provided to clean the filter belt after discharging the filter cake. This procedure prepares the belt for its next operation cycle, and ensures long term, stable and high quality equipment operation.

Features
(1) Our product is light weight with a compact structure, and weighs as much as 20 to 30% less than other similar products available on the market today.
(2) The synchronous operation of the filter plate and filter belt is ensured with an error less than 2mm.
(3) The quick returning of the filter disc allows for a longer effective operating time.
(4) An advanced frequency converter is used in the control system. The vacuum filter plate runs at both low and high speeds, and will adapt to various filtration process requirements. Our system is stable, reliable, easy to maintain and has a long service life.
