Description
Technical field
The present invention relates to filtration art, and in particular to a kind of vacuum filter.
Background technology
Filter (pressure filter) is the equipment that separation of solid and liquid is realized using porous filter machine.Filter should
For departments such as chemical industry, oil, pharmacy, light industry, food, ore dressing, coal and water process.Filter is a kind of new filtering system
System, structure novelty, small volume, convenient and flexible operation, efficient, closed work, be strong applicability multipurpose filter plant.
The operation principle of filter：Suspension filtering has three kinds of filter cake layer filtering, in-depth filtration and sieving modes.Filter cake layer
Filtering：Filtering filter medium at initial stage can only retain big solid particle, and little particle passes through filter medium with filtrate.It is initial being formed
After filter cake layer, filter cake layer is played a major role to filtering, and at this moment large and small particle is trapped, such as the filtering of plate and frame filter press.It is deep
Layer filtering：Filter medium is thicker, less containing solid particle in suspension, and particle is less than the duct of filter medium.During filtering,
Grain is attracted in duct after entering, such as the filtering of porous plastics pipe filter, sand filter.Sieving：Filter the solid of retention
Particle is both greater than the hole of filter medium, and not adsorbent solid particle inside filter medium, such as drum-type sieves filter off sewage
In coarse grain impurity.In the filter process of reality, three kinds of modes often simultaneously or sequentially occur.Liquid by filter cake layer and
Filter medium must pull against resistance, therefore must have pressure differential in the both sides of filter medium, and this is the motive force for realizing filtering.Increase
Big pressure differential can be with accelerated filtration, but the particle deformed after being pressurized easy blocking filtering medium hole in big pressure differential, filtering are anti-
And slow down.
Filter can be divided into board-like sealing filter, vacuum filter, self-cleaning type filter element filtering machine, stud filter
Deng different filters coordinate different filter cores, and it is low, it is necessary to further be lifted that existing filter still has filter efficiency.
