The belt filter press is a new model successfully developed on the basis of introducing foreign filter press technology. It is a filter press equipment that removes moisture from the slurry by winding two filter belts around a series of rollers arranged in sequence and of different sizes, utilizing the squeezing and shearing action between the filter belts. It has the advantages of continuous operation, high degree of automation, energy saving, and easy use and maintenance. It is an ideal equipment for sludge dehydration and volume reduction treatment.
The power of the disc vacuum filter comes from the pressure difference caused by the vacuum. Each disc is divided into several small fan-shaped filter blades to form a filter chamber, which is suitable for filtering suspensions with low density and difficult to precipitate. The fan-shaped filter plate has evenly distributed dehydration holes, reasonable porosity, and long service life.
GW series cylindrical external filter vacuum filter is a vacuum filter with bottom feeding, suitable for filtering materials with coarse particle size, large density and fast sedimentation speed. It is mainly used for dehydrating non-ferrous metal iron, copper, zinc, aluminum, nickel and other concentrates and non-metallic sulfur, phosphorus, talc, fluorite and other concentrates and flotation clean coal after magnetic separation by magnetic separator and flotation by flotation machine. It can be widely used in mineral processing, metallurgy, chemical industry, papermaking and other departments.
Plate and frame filter press is the first machine used in chemical dehydration. Although plate and frame filter press is generally intermittent operation, the capital equipment investment is large, and the filtering capacity is also low, it is still widely used in some small sewage treatment plants because of its advantages such as large filtering driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs.
