Description

[0002] The filter cloth of the vacuum belt dewaterer is installed on an annular belt, and the belt runs on a series of rollers under the drive of a motor. When the material containing solid particles and liquid is transported to the filter cloth, the liquid penetrates the filter cloth into the vacuum box under the negative pressure generated by the vacuum box, and is then discharged through the drainage pipeline. The solid particles cannot pass through the filter cloth and gradually accumulate on the surface of the filter cloth to form filter cake. With the movement of the belt, the filter cake is taken out of the dewatering area and scraped off at the discharge position for collection, thereby completing the whole solid-liquid separation process.
