Features of LDZ Crawler Vacuum Pressure Belt Filter

High degree of automation, it can continuously complete the functions of slurry feeding, vacuum dewatering, squeezing, filter cloth washing, etc., with extremely high production efficiency.
Combining vacuum belt filter, belt press filter and press filter (it can be called a continuous plate and frame filter press) three in one, maximum to remove water.
Reasonable structure, low equipment failure rate, easy to maintain.

Structure & Working principles:

Structure:

Crawler belt vacuum pressure filter is made up of crawler belt cover device, rubber belt, vacuum box, driving roller, belt supports, feeding hopper, filter cloth corrective device, driving device, fabric cleaning device, roller squeeze, frameworks, etc. It is an efficient solid-liquid separation equipment that makes full use of slurry gravity, vacuum, coupled cloth pressing and roller squeeze.

Working principles:

As shown, the annular rubber belt is driven by a reducing motor run continuously, and the filter cloth which laid on the rubber belt run with it synchronously. The rubber belt contact with sliding table of vacuum box (There is an annular friction belt between the vacuum box and the rubber belt, and water is fed into it to form a water seal), when the vacuum box is connected to the vacuum system, vacuum area formed on the rubber belt, the slurry is evenly distributed on the filter cloth by the feeding hopper, as vacuum exist, the filtrate penetrates the filter cloth and is collected by the transverse grooves on the rubber belt and flows into the vacuum box through the holes in the center of rubber belt, while the solid part is intercepted and become filter cake on filter cloth. The filtrate in the vacuum box is discharged by air-liquid separator.

As the rubber belt moves, the cake enters the filter extraction area, cover area and drying area in turn. At the cover area, upper and lower filter cloth wrap together, forming a high vacuum area, while the rollers which in cover area and driven by air cylinders squeezing the cake with great linear pressure, maximum remove water from the cake. At the drying area, the cake is dewatered further, at last, the cake separate with the belt at the cake discharge roller. And the filter cloth renewed by cleaning device re-enter the filter area after passing through a set of support rollers and corrective device.
