Belt vacuum filter 
 Description: 
 Belt vacuum filter plant on the basis of the introduction of similar foreign products, a kind of self-developed vacuum-driven solid-liquid separation equipment. The device is a high degree of automation of new filtration equipment, the aircraft to the filter cloth or filter media, so that the level of slurry arranged above the filter media, and make full use of the gravity of the slurry and vacuum suction to achieve the solid-liquid separation. It continuously and automatically complete the filtration, cake washing, dumping slag, filter cloth regeneration process operation, and the mother liquor and cake washing liquid can be segmented collection. With high filtration efficiency, production capacity, washing effect, low cake moisture, flexible operation, simple maintenance and advantages. I plant for many years to improve and perfect the technical performance and quality of the product has reached international advanced level, has been widely used in metallurgy, mining, chemical, coal chemical, paper, food, pharmaceutical and environmental protection in the field of solid-liquid separation , in particular, has a good application in FGD gypsum dehydration. Belt vacuum filter can be used for the materials under a variety of concentration conditions, high filtration efficiency, and thus many industrial sectors given priority. 

 Features: 
 1, feeding, filtration, washing off the residue, filter cloth regeneration continuous auto-complete, high degree of automation. 
 2, the material multi-level advection or countercurrent washing, the filtrate (mother liquor) and the washing liquid can be separated from the liquid collection. 
 3, the filter is poor, high-viscosity materials, thin-layer rapid filtration. 
 4, modular design, flexible combination of adaptability. 
 5, PLC control, easy remote and centralized control. 
 6, snake-like correction, filter cloth deviation and discounts. 

 Selection Guide 
 1, according to the density of solid-liquid ratio of materials, processing capacity, solid particle size, viscosity, heap, select the device model 
 2, according to the PH value of the materials flow but not the material, select the filter media based on the solid particle size, the material temperature 
 Materials containing volatile gases or vapors can choose semi-enclosed and totally enclosed models 
 4, repeated washing of the material should be selected vacuum chamber length greater than 10 m models, leaching models should be selected on the special washing materials 
 5, suggested a small pilot test of unused materials of the same industry 
 6, the preferred size models prescribed by the National Institute of Standards
