Description
Technical field
The utility model relates to low-power consumption, and machine is filtered by vacuum, more particularly to a kind of low-power consumption vacuum that can continuously filter is taken out
Filter.
Background technique
Low-power consumption vacuum filtration machine is to realize the equipment being separated by solid-liquid separation by motive force of negative pressure of vacuum, in structure, filtering
Section arranges along horizontal length direction, can be continuously finished be filtered, washed, blot, the operations such as filter cloth regeneration.Rubber belt type filtering
Machine has the advantages such as filter efficiency is high, production capacity is big, washing effect is good, filter cake moisture is low, flexible operation, and maintenance cost is low.
Rubber belt type filter can be widely applied to the solid-liquid in the fields such as metallurgy, mine, chemical industry, papermaking, food, pharmacy, environmental protection point
From (FGD) has good application in terms of the gypsum dehydration especially in flue gas desulfurization.
Low-power consumption vacuum filtration machine is that motive force of the negative pressure as filtering is formed at filtrate (liquid.This filter divides again
For two kinds of intermittently operated and continuous operation.The vacuum filter of intermittently operated may filter that the suspension of various concentration, continuous operation
Vacuum filter be suitable for filtering the thick suspension more containing solid particle.
The filter of intermittently operated is developed because being able to achieve automatic operation, and filter area is increasing.To obtain
The low filter residue of water capacity, the filter of mechanical expression are developed.Container is divided into upper and lower chamber, i.e. structure with filter medium
Machine is filtered at simple.Epicoele is added in suspension, enters cavity of resorption as filtrate, solid by filter medium under pressure
Grain is trapped within filter media surface and forms filter residue (or filter cake).
Disadvantage of the prior art is that: the filter cake layer that filtration media surface area is deposited in filter process gradually thickeies, and liquid is logical
The resistance for crossing filter cake layer increases therewith, and the rate of filtration reduces.When filter chamber is full of filter residue or the too small rate of filtration, stop filtering,
Filter residue is removed, regenerates filter medium, to complete a filtration cycle.
And currently, vacuum continuous filter main representative is outer filtering surface rotary drum vacuum filter: can continuously and automatically grasp
Make, can be effectively carried out filtering, wash, dehydration, operation scene is clean, is easy to check and repair.The disadvantage is that it is at high cost, use model
The vapour pressure limitation of heated liquid or volatile liquid is enclosed, low boiling point or material volatile at the operational cannot filter,
It is difficult to handle solid content and mostly changes big slurry with particle characteristics, and filter cake water capacity is 30% or so, be seldom lower than 10%, it is main
It is used for chemical industry, food service industry.
To sum up, current suction filtration machine is also not enough to realize while meeting the water capacity for continuously filtering and guaranteeing filter cake.
