Abstract

The invention discloses a vacuum belt filter dewaterer. Wherein, the filter belt is adhered on the rubber belt of ripple groove that driven by the drive motor as the rubber belt to step for the same direction; the rubber belt ripple groove is connected to the vacuum room; the rubber belt is supported by two lubricative support blocks and sealed by water, while said two support blocks and rubber belt form the vacuum room; the rubber belt outside the vacuum room is aerial via the compressed air when in working to reduce the friction resistance; the filter cake is compressed and dewatered at the front of outlet to attain drier filter cake and reduce the energy for following drying; the filter screen can execute filtration after regeneration. The invention has the advantages that: it uses vacuum filtration, with large filter drive power; the filter cake is mechanically compressed with lower moisture percentage; it can automatically detect the thickness of filter cake, via which to control the speed of filter belt to confirm the uniformity of filter cake; it has lower demand for the solid content of filter liquid; and it can realize continuous operation with high automatic degree and better economic benefit.

Description

technical field

[0001] The invention relates to a solid-liquid separation device for removing solid particles in a liquid phase, in particular to a vacuum belt filter dehydrator. Background technique

[0002] The traditional vacuum belt filter has been widely used in various fields of industry and agriculture, and has always had a large market share due to its simple structure, low price, and high efficiency. Then, because the vacuum chamber of the traditional vacuum belt filter is completely composed of a rubber belt and a supporting object through a water seal, the rubber belt and the supporting body are in direct contact, the contact area is large, the friction is large, and the power consumption is large. Traditional filters have poor adaptability to different solid content rates, and generally can only be adjusted by continuously adjusting the belt speed to adapt to changing solid content rates. Aiming at the above shortcomings, the present invention proposes a vacuum ...
