The working cycle of a belt vacuum filter is divided into a filtration section and a return section. When working, the filter material slurry is evenly distributed on the filter medium (filter cloth) through the feeder. At the beginning of the filtration stroke, that is, the suction filtration section begins, the filter disc and the filter medium move forward synchronously. The vacuum inside the filter disc (chamber) can continuously suction the water in the slurry through the filter medium until the filter disc reaches and contacts the limit device, the vacuum is switched, and the suction filtration section ends; Immediately after the return section begins, the filter disc is pulled back by the reciprocating cylinder, and the filter medium moves forward at its original speed until it reaches and contacts the limit device, and then the next filtration cycle begins. This machine automatically and continuously performs feeding, filtering, washing, suction filtering, unloading, and filter cloth regeneration in a repetitive manner.

belt vacuum filterMain advantages:

① High production efficiency. Continuous feeding, filtering, washing, drying, unloading, and filter cloth regeneration are carried out, with long filtration time, short return time, high system vacuum degree, low filter cake moisture content, and large daily processing capacity.

② Fully automatic continuous operation. The whole machine adopts gas electric automatic control technology, with high degree of automation, stable and reliable operation, low labor intensity for workers, and easy and simple operation.

③ High quality filter cake and filtrate can be obtained, and multi-stage parallel flow washing and countercurrent washing can be performed to achieve the best results at the lowest cost.

④ The filter cloth is completely regenerated. The filter cloth can be continuously washed back and forth during operation, or can be washed empty, with good regeneration effect and long service life.

⑤ Intermittent automatic drainage is possible. Mechanical or electric balanced drainage tank, reliable and stable control, high degree of automation Has considerable flexibility. The filter chamber and frame adopt a segmented structure, which can be combined as needed. The operation of the filter belt adopts internationally advanced variable frequency stepless speed regulation, which can adjust the length of the filtration, washing, suction and other sections arbitrarily, as well as adjust the belt speed and filter disc speed to achieve the best filtration effect and meet strict process requirements.

⑦ Suitable for a wide range of materials. This device has been widely used in dozens of industries, such as chemical, fertilizer, mineral, metallurgical, pharmaceutical, food, environmental protection, etc.
