Description
Technical field
The present invention relates to a kind of grading processing method of sticking with paste resin drying system, be particularly applicable in the method for grading in PVC paste resin production.
Background technology
Stick with paste resin and be widely used in PVC glove, clothing leather, luggage leather, PVC automatic foot-mat, foaming flooring laminate, wallpaper, industrial goods conveyer belt, plastic cement race track, automobile-used decoration leather, plastic-coated screen window, industrial cloth etc.Along with the development of Chinese national economy and improving constantly of living standards of the people, in addition deepening continuously of resin application and development is stuck with paste, domestic market has larger development space to the demand of sticking with paste resin, and particularly in automobile, building, electronics and coating etc., consumption potentiality is large.
Stick with paste raw meal particle size D97≤40 micron after resin drying, traditional technique is all sent in grinder by dried material to grind, but the method has the following disadvantages: one is need a large amount of milling apparatus, and electric power consumption is high; Two be through grinding material finally can only obtain single product.
Summary of the invention
The invention solves product in current PVC paste resin industrial production and can only obtain the problem of single product after grinding, the method of grading in producing by using PVC paste resin, the quantity of grinder can be greatly reduced, reduce power consumption, for the product requirement of different client, the product of different-grain diameter demand can be provided simultaneously.
The technical solution used in the present invention is: a kind of PVC paste resin produce in the method for grading, comprise the spray drying tower be connected successively, one section of bag hose, vibratory sieve, collection powder groove, grader, two sections of bag hose A, conveying worm, two sections of collection powder grooves, pulverizer, two sections of bag hose B; From the latex of latex groove, enter hig h-speed centrifugal spray drying tower, carry out drying to latex, the moisture in removing latex, obtains dry resin-oatmeal; Dried resin-oatmeal, enters one section of bag hose, carries out gas solid separation, is collected in by resin-oatmeal bottom one section of bag hose; Be collected in the resin bottom one section of bag hose, after coarse granule is separated by vibratory sieve, coarse granule collected from the side, pack; The resin-oatmeal got off from vibratory sieve enters collection powder groove, classification is carried out by rotary valve feeding grader at the uniform velocity, fines after classification enters two sections of bag hose A, coarse fodder delivers to two sections of collection powder grooves by conveying worm, the outlet of two sections of collection powder grooves is provided with rotary valve, and undertaken grinding, pulverizing by rotary valve pulverizer of being sent into by resin at the uniform velocity, the resin-oatmeal after pulverizing enters two sections of bag hose B, being delivered to respective feed bin by the resin of two sections of bag hoses by cold wind feed system, packing with packing unit.
The method of grading in described PVC paste resin production, its grader is gas flow sizing machine.
The method of grading in described PVC paste resin production, its grader is eddy current type gas flow sizing machine.Eddy current type gas flow sizing machine utilizes the air of 10% to feed in raw material, play pre-dispersed effect simultaneously, the mixing of materials stream be made up of air-flow and material, at the narrow gap formed through high speed sorting and casing, according to the effect of centrifugal force, gravity, inertia force etc. that variable grain particle diameter is subject in gas, produce different movement locus, thus realize the classification of different-grain diameter particle.
The method of grading in described PVC paste resin production, its grader import department arranges material flow control system.
The method of grading in described PVC paste resin production, its two sections of bag hose A and two section bag hose B exit is provided with cold wind feed system, and two sections of bag hose A and two section of bag hose B exits are all connected with feed bin, are delivered to respective feed bin by the resin of two sections of bag hose A and two section bag hose B by cold wind feed system.
Described PVC paste resin produce in the method for grading, by the inlet temperature of automatic steam control drying tower at 140 DEG C ~ 170 DEG C.
The method of grading in described PVC paste resin production, makes the temperature of drying tower outlet material at 54 DEG C ~ 60 DEG C after super-dry.
Below for the present invention uses the principle of grader: turbine classifier is mainly according to the particle of different-grain diameter size, and the principle that the centrifugal force be subject in rotary pneumatic flow field varies in size carries out classification.The air stream mixing material is introduced into grader bottom, and the air-flow forming a free volute through water conservancy diversion enters the classification chamber of grader, has the grading wheel rotor of a horizontal positioned, by the rotation of grading wheel rotor, produce a rotary pneumatic flow field in classification chamber; The hollow parts of rotating shaft simultaneously causes a negative pressure by exhaust blower, makes the air that carry material enter grading wheel along classifier rotor edge, in the shape of a spiral to turbine central motion.The centrifugal force of thick particle suffered by it be greater than air-flow to the viscosity resistance of generation be thrown out of grading wheel, exported by meal after Secondary Air cleaning and discharge; And fine grained is sucked into rotor center together with air, draws cylinder by fine powder and be discharged to material collector collection.In the application process of reality, the domain size distribution of attentional manipulation resin, enter the control that grader is pan feeding flow, ensure to stablize pan feeding, to reach desirable grading effect.
Beneficial effect of the present invention: by using PVC paste resin grading device, the material of dried PVC paste resin powder 80% does not need fragmentation, the parameters such as material circularity are better, product aft-loaded airfoil performance is good, improve product competitiveness in the market, can be used as gloves PP Pipe Compound to sell, thus produce higher economic worth; Simultaneously only need by after classification 20% coarse fodder just can to meet the needs of product treatment through a pulverizer, sell as another kind of PP Pipe Compound after pulverizing, greatly reduce grinder quantity.Milling apparatus quantity decreases 2/3rds compared with conventional drying processes, and general power decreases 1/3rd.Reduce power consumption, improve economic benefit.The present invention has the advantages such as equipment is few, effectiveness of classification is high, incising control is easy to adjust, energy-saving and cost-reducing, economic benefit is high.The present invention is applicable in the grading process of PVC paste resin drying system.
