Content of the invention
Utility model purpose：
Greatly, filter effect is difficult to the shortcoming of real-time control, provides one to overcome water consumption in traditional spinning slurry filtering technique
Plant the spinning slurry filter plant that solvent refluxing uses, filters low cost, filter quality immediately monitoring and adjustment.
Technical scheme：
Silk slurry filtering equipment of the present utility model, has feeder, dissolution kettle, slurry pool of precoating, spinning slurry filtration
Machine, pans, slurry tank, program control device.
Feeder passes through charge pipe connecting dissolution kettle, and dissolution kettle connects slurry pool of precoating, and slurry pool of precoating passes through pre- tubine
Road connects spinning slurry filter, and spinning slurry filter connects pans entrance, pans by valve A with pipeline A respectively
Further through reflux and reflux pipe connecting dissolution kettle, pans are connected with the temperature controlling the internal slurry temperature of pans for outlet
Degree control device.
Spinning slurry filter connects slurry tank also by valve B with pipeline B.
The function of feeder is to add the raw materials such as pulp, and the function of dissolution kettle is that the raw materials such as filter aid and pulp are mixed shape
Become serosity, the function of spinning slurry filter is to filter through out-of-date formation filter cake and to filtrate in filtrate.
Spinning slurry filter special configuration different structure, material, the filtration of perforate size, porosity and fluid resistance fall
Medium, its Main Function be supporting material, precoat in slurry by dregs of rice fiber it is ensured that filtration treatment reaches the filtrate matter of requirement
Amount, and pressure drop is less it is ensured that end breakage rate can be up to standard during later stage filtrate spray webbing.
Wood pulps are preset with charge pipe and add volume measuring device, pipeline of precoating is preset with time detector of precoating, backflow
Return time detector is preset with pipeline.Serosity sample tap is preset with pipeline A, serosity sample tap is connected to filtrate detection dress
Put, can sample at the end of the process of precoating respectively and sample at the end of backflow, so that filtrates tested is in two time points
Cross filter data, discriminating test effect.
Program control device connects pulp charging amount detector, time detector of precoating, return time by there being holding wire respectively
Detector, filtrate sampling detector, and obtain the signal that they detect respectively.
Program control device connects feeder and reflux by control line respectively, correspondingly controls feeder and backflow respectively
The working condition of device.
The detection signal being obtained by holding wire, program control device adjusts feeder, reflux or spinning slurry in time
The start and stop of filter, reach the purpose automatically controlling multiple component working processes and filter quality.
During work, the raw material of spinning slurry adds in dissolution kettle from feeder and is dissolved into liquid slurry, subsequently enters pre-
Deposited slurry pool, flows through spinning slurry filter, and the few fibers material in liquid slurry forms filter cake, and remaining serosity is filtered simultaneously
Cake filters；During beginning, valve A opens, and valve B closes, and serosity enters pans, the slurry now flowing to by pans entrance A
Liquid concentration is thinning, exports from pans and flow out in pans after being warmed, then passes through return duct under the driving of reflux
Road flows to dissolution kettle, assists dissolved solid raw material, finally flows to spinning slurry filter by slurry pool of precoating again.
The such circulating reflux of serosity, backflow effect is will to take away higher than the moisture in normal serosity in filter cake.The slurry of backflow
Liquid passes through to dissolve further solid feed in dissolution kettle, adjusts the concentration of serosity, moisture therein is reduced.Both protected
In card filtrate, the content of moisture equal solvent is relatively low, and the quality of guaranteed filtration is higher, efficiency that is filtering is higher.
After backflow terminates, valve A closes, and valve B opens, and serosity is entered by valve B and pipeline B from spinning slurry filter
Enter slurry tank.
Detection is sampled by filtrate, support vector machine can be based on again（Support Vector Machine, SVM）Algorithm
And obtain the performance to filtrate and judged and predict, so that the opportunity of the control feeder of program control device and reflux is more
Adduction is managed, and whole filter process automaticity improves, and raw material addition, time of precoating, return time and filtrate quality control
Accurately.
Beneficial effect：
Filter plant of the present utility model has structure simply, and automatic control level is high, and control time, temperature accurately, cross filtering medium
Measure.Before serosity enters spinning slurry filter, the fast temperature of the big flow velocity of pressure is low, can quickly form filter cake, filter cake aperture is relatively
Little, serosity filter quality is good.In pans, the temperature of serosity is higher, good fluidity, enters dissolution kettle and is easy to abundant dissolved solid
Raw material.Slurry reflux ensures that solvent makes full use of, saving water resource, mitigates the living load of equipment.
