Technical economic benefit is impaired.It is high that ZL200810167182.6 patent solves discontinuous
Effect black liquor extraction machine and pulping production line matching problem.By the present invention, bag pressure is filled in reduction
Squeeze and the deslagging time, improve single machine yield, meet scale and benefit and require.
Squeeze and filter device discontinuous be first charging, squeezing, slag tap again after, just complete
Become single pressing.The daily output is the product of single pressing quantity thereof and day squeezing number of times.Increase
Day squeezes number of times and single pressing quantity thereof all improves the daily output.
Both restrictions, it is impossible to simple increase single pressing quantity thereof；Because of its can extend charging,
Squeeze and slag tap the time, affecting day squeezing number of times, it is impossible to effectively improve the unit daily output.
Simple to capsule inflated squeezing, it is for example full of 10m3Volume, arrives 1.2Mpa pressure；
Need to be pressed into 120m3Atmosphere gas, though flow 10m3/ minute air pump, also wants 12
Minute.
Inflated squeezing further drawback, is that the filter cake thickness squeezing out has a difference, upper thin under
Thick.Its reason is, starts when capsule is inflated, and solidliquid mixture proportion is much larger than inflation
Hollow capsule, the capsule being gradually increased volume produces buoyancy, causes capsule top first to expand,
Forcing and being squeezed the downward sliding of material, consequence is filter cake upper-thin-lower-thick.
Topping up squeezing in capsule, high-capacity pump lift is inadequate, and middle high-pressure pump discharge is little.
For shortening the squeezing cycle, first can fill low pressure liquid in capsule with high-capacity pump, squeeze out
After portion filtrate, switch to high-pressure pump and continue to be filled with liquid in capsule, improve pressure pressure
Squeeze.
But, in emptying capsule, the liquid time is long.As long as beginning discharge opeing, just release in capsule
Pressure, by nature trickling discharge opeing, speed is slow, uses duration.To this end, enter from capsule top
Gas port, inflates in capsule, forces CF body quickly to be discharged, and shortens capsule emptying time,
Improve the daily output.
Therefore, the present invention is first topping up, reinflated.Liquid is incompressible, occupies capsule
Internal volume, significantly reduces aeration quantity, shortens the inflated squeezing time.
Fluid filled sac is very little with solidliquid mixture specific gravity difference, during topping up, from capsule top to
Bottom even inflation, will not force supports for material down-sliding.First topping up squeezing, filter cake is tentatively fixed
Type positions, and reinflated raising pressure squeezing, filter cake does not glides, and filter cake thickness is uniform.

Gas inlet and outlet is arranged at capsule top, and liquid entrance is arranged at bottom.It first in capsule, is filled with liquid
Squeezing, then switching is filled with higher pressure gas or liquid squeezes.After squeezing, lean on gas
Pressure forces liquid emptying in capsule.Thus, reduce the single squeezing time, improve unit
The daily output, and overcome simple by gas squeezing, the shortcoming of filter cake upper-thin-lower-thick.
Another object of the present invention is to provide the pressure improving volume space and hollow capsule shape
Squeeze filter.Its screen area is big to volume ratio, when reduction capsule pressurising and capsule emptying
Between.
Another object of the present invention is to provide the squeeze and filter that heavy in section slag notch is arranged at bottom
