Abstract
The present invention discloses a vacuum belt type filter and dehydration machine. A filtering belt is tightly attached to the upper surface of a rubber belt with a corrugated tank, and is driven by a drive motor with the rubber belt to forward move along a direction. The corrugated tank of the rubber belt is communicated with a vacuum chamber, the rubber belt is supported by two supporting blocks with a lubricating function and is sealed by water, and the two supporting blocks form the vacuum chamber with the rubber belt. The rubber belt outside the vacuum chamber is overhead by compressed air when in use, and thus, friction resistance can be greatly reduced. A filter cake is further pressed for dewatering before an outlet, and thus, dry filter cake can be obtained, and energy for subsequent drying is saved. Filter operation is newly carried out when a filter net is regenerated. The filter has the advantages of vacuum filtration, large filtration driving force, low water ratio of the filter cake by mechanical pressing, continuous operation, high automation degree and good economic benefit. The thickness of the filter cake can be automatically detected in the operation process, the filtration carrying speed can be controlled by the thickness of the filter cake, the uniformity of the filter cake is ensured, and the requirements to the operating flexibility of the solid content of filter liquor are low.
