The ZD belt vacuum filter
 
   On the basis of the introduction of similar foreign products, The ZD belt vacuum filter is an independently developed device that uses vacuum as driving force to separate solid and liquid. The device is a new filtration equipment with high degree of automation. This device regards the filter cloth or filter as media, arranging slurry above the filter media horizontally, making the full use of the gravity of the slurry and vacuum suction to achieve the solid-liquid separation. It can continuously and automatically complete the process operation of filtration, cake washing, dumping slag, filter cloth regeneration and so on. At the same time, the mother liquor and cake washing liquid can be collected in segment . It has advantages of high filtration efficiency, strong production capacity, good washing effect, low cake moisture, flexible operation, and simple maintenance. After many years of improvement and perfection, the technical performance and quality of the product have reached international advanced level,which has been widely used in solid-liquid separation of the field of metallurgy, mining, chemical, coal chemical, paper, food, pharmaceutical and environmental protection. In particular, it has a good application in FGD. Because the belt vacuum filter can be used for the materials under a variety of concentration conditions, and has high filtration efficiency, it has been given priority of many industrial sectors.

1. Features:
1. Feeding, filtration, washing off the residue, filter cloth regeneration can complete continuously and automatically, which has high degree of automation.
2. Multi-level advection or countercurrent washing can be executed to the material ,and the filtrate (mother liquor) and the washing liquid can be collected separately.
3. For the poor filter and high-viscosity materials, rapid filtration of thin-layer can be achieved.
4. Modular design, flexible combination and strong adaptability.
5. PLC control, easy to remote and control centrally.
6. Snake-like correction has handled the problem of deviation and discounts of filter cloth .
