In the batching of solar energy backboard, there is application according to two kinds of the differences of material characteristic.Conventionally feed proportioning system is divided into feed proportioning (i.e. online broken batching) and broken material (being that stock's broken material is prepared burden) two kinds of preparing burden, and wherein broken material is divided into two kinds of online broken material and stock's broken materials.
Wherein the batching flow process of online broken material is as follows: in process of production, the slitter edge of goods is cut, entering online disintegrating machine is broken, under the positive pressure of roots blower, the material after fragmentation is blown in cyclone separator, wherein most broken material enters in the hopper with weight-loss metering and (also claims weightless hopper), after the dust of small part is filtered, enters dust arrester.Broken material together enters transition hopper with allotting required other material after weighing by formula institute accounting row, various materials by static mixer repeatedly mix laggard enter main frame hopper.After the weighing balance in main frame hopper, be evenly transported to main frame feed opening with crossing conveying screw rod.
The batching flow process of stock's broken material is as follows: stored the broken material of certain hour owing to being exposed in atmosphere always, should finish-drying before reusing, roller drying function makes large-tonnage material lose moisture and reach instructions for use in the dry run that reaches 2 hours.Material after being dried prevents the secondary moisture absorption, is placed in airtight storage bin, by the suction function on cyclone separator, material is drawn in weightless hopper.By being together pooled to transition hopper with other material after accurate measurement, enter into main frame hopper by the static mixer of transition hopper below for subsequent use.
And the blending process of raw material is as follows:
The finished product raw material buying, particle is little and even, and moisture absorption degree is less than stock's broken material, and only needing Hopper Dryer to be dried can be up to standard.Material after being dried prevents the secondary moisture absorption, is placed in airtight storage bin, by the suction function on cyclone separator, material is drawn in weightless hopper.By being together pooled to transition hopper with other material after accurate measurement, enter into main frame hopper by the static mixer of transition hopper below for subsequent use.
In blending process, transition hopper place is used mechanical mixture conventionally, drives agitator to make every effort to the even of material by power, and the mixed material of this mode is a defect to the high-quality solar energy backboard of production high accuracy.The static mixer that the present invention adopts, static mixer is a kind of advanced person's unit, different with agitator is, its inside does not have moving component, to utilize the flow regime of the mixed cell structural reform fluid being fixed in pipe in pipe, to reach fine dispersion and well-mixed object between different fluid.The mixed process of static mixer is that the mixed cell of the different size in hollow pipe by series installation carries out.Due to the effect of mixed cell, while making fluid and left-handed, time and turn right and revolve, constantly change the mixer direction that flows, not only core flow is pushed to periphery, and is pushed peripheral fluid to center, thereby cause good radially mixed effect.After well-mixed material is dissolved into screw rod, plasticizing is even naturally, improves accordingly quality of item.
Conventionally in check hopper, whether material is enough, is by being arranged on the height stuff level switch on hopper, and in the time that material reaches the stuff level switch of high point, it is fracture that the control module on PLC receives signal; In the time that material reaches the stuff level switch of low spot, it is feed supplement that the control module on PLC receives signal.Solar energy backboard production line uses weight-loss metering feeding, weightless title is the automatic weighing equipment that a kind of mode by static weighing realizes high accuracy continuous dosing of very, it can carry out reliable, accurate and stable feed to the dry loose material such as powder, particle, sheet, reduces the waste of material and the uniformity of raising mixture.Weightless title, weighs weighing hopper and whole feeder as a scale body, along with material flows out from weightlessness claims, control system is carried out a high speed to the weight signal of scale body, the collection of high frequency, draw the weight that in the unit interval, in weighing hopper, material reduces, again by filtering, optimization process, draw the weightless actual flow velocity claiming, simultaneously control system can be by this delivery rate and default given speed comparison, and after being calculated, comparative result feeds back to the weightless feeder claiming automatically to revise the delivery rate of feeder, form closed-loop control, allow actual flow velocity infinitely approach given flow velocity with this, thereby reach control requirement.
The pressure in main control system exit, generally adds a measuring pump in head porch in prior art.One, this not only needs certain mixing time, causes the waste of cost, and can, to causing fluctuation between main frame and head, make discharging inhomogeneous, and products surface quality is bad; Its two, can cause a certain amount of backflow in measuring pump inside, test-run a machine personnel's operant level is required very highly in test-run a machine process, be not easy operation.The present invention breaks original mentality of designing on this basis, adds a weightless metering device that claims on the hopper being connected with main frame, and the rotating speed that makes feed screw matches with weighing, and has broken original equal-volume defect of weight such as not.Measuring pump is not installed, not only cost-saving but also can not cause the accumulation of feed screw feed opening place material, make material remain flat two distinctive hunger-type feedings, make goods reach high-quality requirement.

2), far above equivalent material.
(2) dimensional stability is high: in the time requiring plastic material precise measure, dimensional stability will be got well, and the available heat coefficient of expansion represents, thermal coefficient of expansion is less, and dimensional stability is better.The thermal coefficient of expansion of solar energy backboard notacoria prepared by equipment described in the present embodiment and method is less than 6 × 10-
5k, much higher compared with its dimensional stability of common material.
(3) wet and heat ageing resistant is good: macromolecular material in use, under temperature and humidity and double influence, the degree of aging of wet-heat resisting effect in atmosphere border.In test, micro-general technology by advanced person is exposed to solar energy backboard membrane in moist atmosphere, stand together to test some performances or the appearance change before and after exposing after hyther with common material, find that performance or appearance change are less, the wet-hot aging performance of the material that therefore prepared by equipment described in the present embodiment and method is all higher than common material.
