Classification and characteristics of vacuum belt filter

Vacuum belt filter is a vacuum negative pressure as the driving force to achieve solid-liquid separation equipment, vacuum belt filter classification and features:
Intermittent vacuum filter:
Vacuum filter and pressurized filter mechanism is basically the same, but the filter medium side pressure below atmospheric pressure, the driving force is small. Vacuum filter: simple structure, the filter driving force than the gravity filter. Vacuum leaf filter: simple structure, suitable for general mud-like material filtration, but the operating conditions are poor, higher labor intensity.
Disc vacuum filter: according to the unit filter surface count the lowest price, small footprint, but the filter cake humidity higher than the drum vacuum filter. As the filter surface for the vertical, filter cake thickness uneven, easy to crack, easy to wash, thin cake cake discharge difficult, filter cloth wear fast, and easy to plug. Easy to handle the settlement speed is not high, easy to filter the material, not suitable for handling non-sticky material, the scope of application and drum vacuum filter the same.
External filter drum vacuum filter: continuous and automatic operation, can effectively filter, wash, dehydration, clean the operation site, easy to check and repair. The disadvantage is the high cost, the use of limited range of hot liquid or volatile liquid vapor pressure limit, low boiling point or volatile material at the operating temperature can not be filtered, it is difficult to deal with solid content and particle characteristics of large changes in the slurry, and filter cake Moisture content of about 30%, rarely less than 10%, mainly for the chemical industry, food industry.
Inner filter drum Vacuum filter: suitable for filtering solid particles uneven thickness of the suspension, no mixing device, the machine cost is low, can adapt to changes in feed concentration, if you need to operate at high temperatures, it is easy to take insulation measures The The disadvantage is that the drum surface can not be fully utilized, the filter cake needs a certain viscosity, or easy to fall off, resulting in decreased vacuum, the feed flow changes;
Turntable vacuum filter: simple structure, the washing effect is good, the washing liquid and the filtrate separately, for the fast dewatering slurry, a single filter handling capacity, the disadvantage is that the area is large, filter cloth wear fast, and easy to plug The
Dump Vacuum filter: can filter viscous materials, adaptability, suitable for the separation of solid content of solid content greater than 20%, the density is large, and easy to separate and filter cake to be fully washed slurry, commonly used in chemical, Light industry and other industries.
Belt vacuum filter: sub-fixed room, mobile room, filter belt intermittent movement of three, belt vacuum filter is the level of filtration, the above feeding, high filtration efficiency, washing effect, filter cake thickness adjustable, Filter cloth can be both positive and negative at the same time washing, flexible operation, low maintenance costs can be applied to the chemical industry, pharmaceutical, food industry, for the faster settling of the slurry separation performance is excellent, when the cake needs to be more excellent washing.
