Specific implementation mode
The present invention will be further described with reference to the accompanying drawings and examples, does not limit the present invention.
Pressure regulator valve 3.3.2 is first adjusted to 0.3Mpa when booting, then start variable-frequency motor 1.1.2 drive rotary drum 2 by 30 circles/
Minute slow rotation, then opens pan feeding valve 1.2.1, and the Chinese chestnut bud slurries through previous process slagging-off are with >=0.3Mpa pressure entrance
In outer tank 1, and along multilayer, staggeredly the interspersed tortuous passageway formed tosses about downlink to flat, oblique spacer ring gradually from top.Small molecule therebetween
The tanning solution of amount ingredient enters through the ultrafiltration membrane of jacket type pan 2.4 within rotary drum, the pigment solution of macromolecule ingredient
It is intercepted to continue traveling downwardly to outer pot bottom, enter among lower hollow stub shafts 1.3.1 from discharge hole 1.3.5.
Level-sensing device 1.2.2 detects and shows material position when pan feeding to set amount, opens outlet valve 1.3.6 at this time and starts self-priming
Pump 3.The solution being trapped in outer tank is arranged through outlet valve to next procedure as separated pigment composition；Permeate in rotary drum
As separated tannin ingredient, from drainage hole 2.2.5 through input terminal pipeline 3.1 by self-priming pumping, and it is sent into gas-liquid separation
Air-liquid separation is carried out in device 3.3, wherein the gas mixed is continuous from upper end cover 1.1 along the appendix 3.3.1 on the separator top
Into the smaller space in outer tank top（Most of space is occupied by slurries in tank）, gradually accumulation quickly forms air pressure, and oppresses liquid
Surface strengthening slurries penetrate the energy of filter membrane, and when pressure reaches 0.3Mpa, which acts on gas-liquid separator lower part simultaneously again
Permeate, then compressing pressure regulator valve 3.3.2 is opened, which arranges through flowmeter 3.3.3 meterings to next procedure.It opens at this time
Liquid-filling valve 1.1.7 injects alcohol solvent by the flow rate at flowmeter with the pressure of >=0.3Mpa into liquid injection pipe 1.1.6,
The alcohol solvent disperses through more branch pipe 2.2.4 in slurries of the note into outer tank again through the slot hole 2.2.3 that is infused, and with the rotation of rotary drum
Turn fully to be stirred evenly, to make up the loss of solvent in slurries, to reinforce mass transfer, increase permeable membrane amount.
Under the lasting suction of self priming pump, considerable part gas is discharged into outer tank top by related take away in rotary drum, in rotary drum
Portion forms certain negative pressure, and vacuum degree is fluctuated in negative 0.2Mpa in vacuscope 1.1.4 Display Drums, and Instrument for Pressure 1.1.1 is shown in outer tank
Pressure is fluctuated in 0.3Mpa, i.e., both sides pressure difference is accumulative inside and outside rotary drum reaches 0.5Mpa, which drives slurries small molecular amount
Largely quick permeable membrane is segregated into rotary drum ingredient, is constantly arranged to next procedure by self-priming pumping, and intercepted macromolecular
Amount ingredient also accelerates to flow at positive pressure to arrange outside tank bottom.This is during one, level-sensing device by man-machine interface operation bench adjust into
The opening degree for expecting valve and outlet valve, to maintain the dynamic equilibrium state into and out of slurry in innage.
On-line checking flows through the trapped fluid of outlet valve, when there is micro permeate ingredient, simultaneously closes off pan feeding valve and self-priming
Pump and liquid-filling valve immediately open solenoid valve 1.1.9 and motor speed are adjusted to high speed, and the pressed gas moment on outer tank top is by joining
Take over 1.1.8 enters from venthole 2.2.1 in rotary drum through upper hollow stub shafts, and positive and negative pressure disappearance switchs to inside and outside both sides balance, electricity
Machine drives rotary drum high speed rotation in short-term, resulting centrifugal force by the blocking substance for being attached to ultrafiltration membrane appearance throw away pan with
Slurries downlink.Motor switchs to normality and slowly operates in 5 seconds, closes solenoid valve successively and opens pan feeding valve and self priming pump and fluid injection
Valve, whole device restore rapidly normal filtration discrete state.
Automatic repetitive cycling above procedure, completes filters detached job.
