Description
Technical field
The present invention relates to the method for the equipment of operation gummed chip or fiber in plate of material manufactures, and relate to a kind of equipment for gluing together.
Background technology
Such as, at present, from chip or medium density fiber or other free-pouring material, manufactured materials plate is the production process of automation, and is applied in many countries for many years.As everyone knows, suppressing the chip processed or fiber is not be exactly periodically carry out continuously.Although except being positioned at the many parts of appliance before and after forcing press, producing by means of spreading machine and scatter material cushion and also play a part outstanding.But except raw-material quality, the quality of the distribution material cushion produced but is important factor.Manufacture in composite wood boards at heavy industrialization, adopt the forcing press of continuous operation to put into production, but part or single-stage or multistage forcing press.Urgent hope natural material and TPR condensation material carry out the cheap plate of material of manufacturing price forces the producer to go the more effective manufacture method of exploitation.Wherein special emphasis be cost of energy, keep same quality under raw material and the saving of glueing material, and the equipment structure of the technical optimization that down time is short and loss is low.
Current development relates to the optimization that consumes glueing material and also has the saving of cost of energy thereupon.Because when being optimized gummed with the adhesive that water content is few, not only because adhesive consumption reduces costs less, and in chip/fiber, the dry amount of adhesive in drying machine diminishes, and which again saves energy and cost.Substantially adhesive is interpreted as so-called bonding flotation fluid (Klebstoffflotte), its main component is made up of jointing material.Also added emulsifying agent, curing agent, formaldehyde adsorbent, dyestuff, insecticide, mould inhibitor and other additive etc. in addition as required.Usually the jointing material not having additive can also be used.As binding agent, do not ask complete, following material surely belongs to the row of consideration: isocyanates, MDI, melamine urea formaldehyde (MUF), urea-formaldehyde (UF), MUPF or PF.
In principle according to state of the art, in the production equipment for board made of particles or fiberboard, come veneer(ed) wood or fiber by means of nozzle.Now, on nozzle fragmentation binding material chip binding material being sprayed at movement or fiber.Here, two kinds of gluing methods be distinguished, the spray process on the chip rotating mixing, or the spray process on the fiber passed through at a relatively high speed.
Chip provides with ready-made chip usually, or manufactures chip at the scene, and inputs for gummed before the drying or afterwards.Fiber can be manufactured at the scene by fiber pulverizer, and after the pulverizing, between two machines, is transported to drying machine by carrier pipe (English: blow pipeline).According to instrument size and equipment structure, this carrier pipe can have the length reaching 100m.In transportation, it preferably carries out with ultrasonic speed in the relatively little pipe that diameter is less, and fibres bond gets up and is then transported in drier.Then, chip or fiber spread to substrate (Unterlage), and are pressed into plate of material by means of forcing press.In carrier pipe, carry out high pressure bonding is occur special challenge, because flow very turbulent flow, with 7x10
5to 3x10
6reynolds number occur.Now fiber speed moves in the approximate range being at least 50m/s to 474m/s.Usually, the binding material nozzle needed for bonding is delivered in carrier pipe or mixing apparatus (the bonding cylinder of rotation and/or the hybrid element with motion), and this mixing apparatus makes binding material scatter, to be injected in the tiny area of many places by binding material.Adopt so-called atomizer can be the size of roughly 100 to 40 microns by binding material atomization.But also must use high pressure nozzle work, this high pressure nozzle is by unloading the binding material being pressed in another pressure span and dissolving on shower nozzle for this reason.This nozzle is subject to high wearing and tearing.
Can knowing the method and apparatus of the material for gluing together chip, fiber or like fibrous according to DE102008059877A1, utilizing this equipment, jointing material was mixing with vapor phase before nozzle ejection.Now, the dispersion be optimized to make binding material, need provide the flowing of greatly turbulent flow in high-temperature steam and nozzle hybrid chamber.This is particularly advantageous when high pressure bonds, because when there is pressure in carrier pipe (blowing pipeline), preferably inject the pressure higher than carrier pipe.This injection also can controlledly with meticulous adjustment because pressure reduction is no longer conclusive criterion, but the pressure distribution optimized in carrier pipe and mixing apparatus.The injection that this shows binding material in fluid or suspension (semifluid) and dispersion pattern, MDI, UF, MUF and PF are particularly suitable for by current described method or equipment.
A special aspects of the disclosure text is, nozzle should be made to have arbitrary throughput scope, and meanwhile, the glue consumption of every throughput should keep equal.Although generally speaking can successfully use this equipment and method, in other, still there is shortcoming.
One disadvantageously, constantly will prepare the steam for gluing together, the preparation of this steam proves that for atomization be favourable substantially, but is disadvantageous from cost accounting, because undying steam Synthesis and applications, significantly increases the price of final products.
Substantially, when equipment de-sign, there is following problem: if be 30t/h (30x10 per hour by the equipment de-sign of the chip or fiber of producing gummed
3kg) output, then also determine gummed its quantity of nozzle and gummed form (carrier pipe, gummed cylinder ...).Certainly, equipment so no longer oepration at full load, but also produce low-density plank, during gummed, per hour of low-density plank needs the material throughput of 1/3rd or half.Now, especially when gluing together, problem is that glue consumption is not directly proportional to low material throughput, and is almost 1/3rd of throughput when low glue consumption.If be about the theoretical example of the binding material consumption of 3000l/min (liter/min) from 30t/h output, so, when the material throughput of 15t/h, be not as needed 1500l/min consumption expectantly, but 1800l/min, to reach the result of optimization when gluing together.With veneering equipment compared with compared with glue consumption higher than designing during underload, this difference can up to 20% and more than.So, produce low-density thin plate to just very expensive equipment operator, because the high expense of thin plate is just linked up repeatedly with trust business, so when thin plate produces the deal of half (in the annual production about), because the higher meeting of glue consumption makes profit reduce significantly.For binding material, also depend on large-scale chemical enterprise as device fabrication person corporate boss, they can be dominated the price of its glue and improve price termly.
Summary of the invention
Task of the present invention proposes the method and apparatus for gluing together chip and/or fiber, even if throughput is different in time per unit, equipment also or can be equipped with in the delivery tube of conveying device at mixing arrangement, is that similar or even identical glue consumption is to glue together chip and/or fiber with every quantity of material.
The solution of this task is, for the method for driving arrangement, the method given maximum as far as possible fiber/chip throughput can be allowed to realize based on gummed by time per unit, before binding material contacts with fiber or chip, binding material can be allowed with steam to become steam-binding material mixture, binding material 5 or steam-binding material mixture spread out in delivery tube or mixing apparatus through the particularly adjustable opening of at least one nozzle, and contact with fiber and/or chip, wherein, until throughput reaches 66% of maximum possible throughput, preferably reach 50% of maximum throughput, the binding material as steam-binding material mixture is made to realize contacting with fiber and/or chip.
The solution of this task is, for bonding device, at least one nozzle for gluing together is set, wherein, this nozzle is connected with mixing arrangement or delivery tube by least one opening, this nozzle has at least one for regulating the adjusting device injecting binding material amount in delivery tube or mixing apparatus, wherein, at least one jet chimney and at least one binding material pipe arrangement are on this nozzle, wherein, jet chimney and binding material pipeline with or a few hybrid chamber be connected, and steam valve is substantially adjacent with hybrid chamber or be arranged in adjacently in jet chimney.
Preferably, the present invention's theory now can be to regulate gummed mode according to the throughput of time per unit actual fibers/chip or with moistening to fiber/chip of binding material, and give operator's measurement rules, namely, when playing application is only significant/necessary as the binding material of steam-binding material mixture, when be not significant/necessary.When binding material throughput is high, because equipment works in the upper area of design maximum, so, be directly atomized binding material by means of nozzle just enough, this is because binding material pressure in nozzle for the best atomization enough high.If binding material throughput decline in nozzle, then less because of chip/fiber that time per unit must glue together, nozzle hypergeometric is optimized bonding capacity routinely and is declined.Due to this cause, in general, time per unit has than there being the originally required more binding materials of successful bond quality to be atomized in order to ensure chip/fiber, and this obviously improves the pressure in nozzle.As already noted, in order to produce steam-binding material mixture, connect this operation area (the binding material throughput of time per unit is less in nozzle/veneering equipment), instead of provide more binding material steam also just enough.Steam pressure in nozzle and in corresponding hybrid chamber is atomized the binding material of small amount but still arrives optimization.Also accessiblely be, in the gummed optimized further, by combination, the binding material for high pressure region/throughput, the steam-binding material mixture for less pressure span/throughput, can reach best gummed with minimum binding material amount always.The steam expenditure of producing and apply, compared with saving binding material amount, is obviously favourable to cost.Suitable nozzle and control device can be changed between binding material and the atomization of steam-binding material mixture, can neglect suitable nozzle and the allowance for depreciation of control device in this long-life equipment.
Nozzle becomes to make the hybrid chamber that is suitable for producing steam-binding material mixture and jet chimney to be separated with preferably patten's design.Preferably load black/white valve (Schwarz-wei β Ventil, flickering valve) thus.But also can expect according to bleed type, arrange a sleeve pipe in hybrid chamber, it can be passed through the opening of jet chimney.This point is favourable, because when not using jet chimney, binding material can be made to be pressed onto in jet chimney until valve.If this valve from hybrid chamber too away from, then binding material here can lump, and valve can be made dirty or damage during injection once on steam.Therefore valve is proposed with regard to its closure function as far as possible near hybrid chamber, namely adjacent with hybrid chamber or arrange adjacently.So-called adjacent, people are interpreted as that the separation of hybrid chamber is directly on the opening of jet chimney leading to hybrid chamber, and so-called adjacent, people are interpreted as that distance can reach 20cm, preferably can reach 10cm.This nozzle is as double nozzle design (steam and binding material), and wherein, jet chimney can be closed.The enforcement of equipment not only for method of this proposition is suitable especially, and also very independent and can find application for the operation of equipment.
Especially, astoundingly and existingly to show sharply, when the throughput of time per unit is higher, steam can be saved with proposed method and apparatus, because making in the operation area of optimal design to it, when high pressure and the application along with nozzle, in order to the good decomposition reaching binding material is no longer necessary by steam injection nozzle.If the throughput of time per unit and the binding material amount that must be sprayed by nozzle are reduced only about half of (dropping to 20l/min from 40l/min) thereupon, then the pressure in nozzle also reduces.This is adjusted among a small circle by controlling A/F, but unfortunate accurate not.Consequently, nozzle no longer optimally works, and the decomposition quality of binding material obviously degenerates.But the quantity of nozzle meanwhile, is but determined when designing apparatus.Cannot shut the nozzle of half, to keep the best throughput of binding material thus in remaining nozzle, because the spray site be then injected in material to be glued together is a half suddenly, this brings equally again bad gummed.Preferably, the present invention here now proposes, and only in effective coverage (Leistungsbereich), accesses steam, does not work at this region inner nozzle in the pressure span optimized and effective coverage.Now preferably advise in lower 2/3 region of this effective coverage steam being linked into nozzle and relevant device, but at least over half.Therefore, in one embodiment, in the equipment being designed to 30t/h, the steam in gummed nozzle in time being about the output of 20t/h (2/3), but is especially connected when more than 15t/h (1/2).By connecting steam in these effective coverages, superproportional glue consumption in effective coverage, bottom just can be suppressed, so, the same with equipment full load, be expected to reach approximately same glue consumption.Nature, conceptively must count steam consumption (steam production), but it is much lower compared with the consuming cost of time per unit binding material, even almost can ignore at this, so, bring further reduction effect to the operator of equipment like this.
Wherein directly be also advantageous in that, the light and automation of the described weight of equipment in mentioned nozzle area, especially, cleans to preventability.Also can get rid of the blocking on nozzle head or bonding, and be removed immediately by affiliated adjusting device.Similarly, when accessing steam, self-cleaning effect is provided by vapor stream.
From attached claims and referring to the description of accompanying drawing, measure and the structural configuration of the further advantage of the present invention will be provided.
