Description
Technical field
The present invention relates to a kind of method that is used for operating equipment as described in the preamble according to claim 1, this equipment is used for making fiberboard, MDF, HDF, composite wood boards or plastic plate with fiber or similar fiber.In addition, the invention still further relates to a kind of equipment as described in the preamble according to Claim 8.
Background technology
The manufacturing of making plate of material with medium density fiber or similar material is automation process at present, and for many years in many national extensive uses.As known in the art, or according to certain rhythm, or suppress wood chip or fiber after the preprocessing in a continuous manner.Yet except having many units before and after press, what play a crucial role is to make slab by spreading machine; Except the quality of raw material, the quality of made slab also is a key factor.When composite wood boards is made in large-scale industry, use continuously operating press, but partly also use lamina or multi-layer sheet press.Raw material and the artificial binding agent pursued with nature come the cheap plate of material of manufacturing price, force manufacturers to go the more and more high efficiency method of exploitation.In the case, focus on especially quality remain unchanged under the situation energy cost, conservation of raw material and binding agent saving and have few downtime and the device structure through optimizing technically of low wearing and tearing.In principle, binding agent refers to so-called adhesive bleaching and dyeing liquid, and the key component of this adhesive bleaching and dyeing liquid comprises adhesive.As required, additionally add emulsion, curing agent, formaldehyde scavenger, colouring agent, desinsection and bactericide and other additives.Usually also use the adhesive that does not have additive.Do not attempt exhaustively, as binding agent can be: isocyanates (MDI), melamine urea formaldehyde (MUF), urea-formaldehyde (UF), MUPF or PF.
Gluing has been supplied or made at the scene and sent to these wood chips usually before or after drying as wood chip.Fiber then is to be transported to drier by carrier pipe after the fibrillatable of making at the scene by fiberization equipment and carry out between two mills.When by steam cooker fiber being decomposed, unnecessary steam is used to drive these fibers and passes through carrier pipe.According to instrument size and device structure, carrier pipe can have the most nearly 100 meters length.During the preferred conveying of carrying out in the less relatively pipe of supersonic speed at little internal diameter, fiber is gummed and is admitted to subsequently drier.Can produce big challenge when in carrier pipe, carrying out the high pressure gluing, extremely rapid have 7 * 10 because can occur
5To 3 * 10
6The flowing of Reynolds number (Reynoldszahl).In the case, the speed of fiber fluctuates in the scope of the speed of 474m/s at 50m/s at least.Subsequently, these wood chips or fiber are dried, are placed in the feed bin usually, being mated formation quantitatively is pressed into plate of material to base plate and by press.
So far, introduce carrier pipe in order to carry out the necessary binding agent of gluing with nozzle, these nozzles are so broken up this binding agent, so that preferably spray into this binding agent with the size in the micrometer range of long number.Utilize so-called atomizing (pressure) nozzle binding agent roughly can be decomposed 100 to 40 microns size.But necessary for this reason is that the high pressure nozzle that use is broken up the binding agent at nozzle head place by the step-down in another pressure span is worked together.Up-to-date research and development has been pointed out wherein by steam this binding agent to be dispersed as molecule when binding agent is discharged from or in nozzle about spraying the new way of possibility.In the case, the above-mentioned 40 microns point of binding agent can be dripped size and reduce the most nearly 20 microns once more.For the Optimal Distribution of the binding agent during rapid fibre high-speed flows, urgently preferably binding agent is dispersed as minimum.
When fiberboard was made, fibrous material had been admitted to drier and is being dried during the gluing or after gluing, is admitted to tube drier and is dried in preferred embodiment.For drier air and dried fibrous material are separated, usually use cyclone separator, wherein purify the drier air of making dirty as the quilt of waste gas in the prefilter and burn this drier air subsequently usually according to being defined in of necessity or Environmental Technology aspect.Employed in the case method is known and obtains implementing in the device that is called as " RTO=heat accumulating type heating power incinerator ".After cyclone separator, dried fibrous material is placed in the feed bin and is discharged into paving station as required, and this paving station is configured as fibrous material slab and carries this fibrous material towards the direction of press on the forming belt of continuous motion.Usually, after slab is carried out precompressed or preliminary treatment, this slab is sent into continuously operating press and by pressure and heat this slab is pressed into plate of material.After compacting, the surface is carried out flat surface grinding and is cut into pre-sizing with subsequently destacking.
Nowadays, the network operator of fiber manufacturing equipment will thank to little order, so that guarantee to make full use of the production in 24/7 cycle.Therefore, several hours or even to move identical product type more than several days no longer be common always, but to repeatedly change the production thickness and/or the production density of the plate of material of wanting manufactured every day.This means that the flow of fiber in carrier pipe is complementary with needed amount through rubberized material regularly.
Before raw material crises took place, effectively and to carry out gluing in carrier pipe be unessential with saving material, this was especially all the more so under rare little surplus situation.As described, marked change has taken place in this situation, and the equipment network operator wishes to realize optimum and at first be the gluing of saving for all types of flows.So far, the optimization of gluing is to control by the pressure of wanting injected binding agent equally, and in the case, bigger flow of material is corresponding to high pressure, and the materials with smaller flow is corresponding to lower pressure.This also is associated with following situation: the injection cone of binding agent contacts Face to face in inner radius, binding agent clings there and form blob of viscose.But these solutions have been proved to be to be had very large wearing and tearing and not to cause optimum result for nozzle, especially all the more so under the flow of material situation that changes.Be used for saving binding agent or be used for for example can in DE 16 32 450 A1, finding in other solutions that carrier pipe optimally is coated to binding agent on the fiber of motion; Its disclose a kind of be used for continuously will be relatively in a small amount the device that mixes with carrier material of tiny component by air motion.In this publication, in carrier pipe, do not use steam and be only applicable to very little flow.The solution that goes out mentioned herein is, neatly carrier pipe is designed to all parts and handles this carrier pipe with percussion mechanism in case of necessity, just can not form bonding thus.In addition, also propose simultaneously to rotate this carrier pipe or enduringly this carrier pipe is divided into a plurality of carrier pipes.Wherein, only used static solution herein and coupling with flow has been set.
DE 195 06 353 A1 have pointed out a kind ofly to be used for coming wetting method and apparatus, this method and apparatus to attempt in jeting area cross section targetedly by carrier pipe with fluid and to change and improve the gluing result.In the case, preferably before nozzle, reduce the diameter of carrier pipe, so that increase the turbulent flow in the Mixed Zone.With the coupling of different flow be to realize at this by the project organization of nozzle, but its to be proved to be in practice be not to be optimum.
After this several years show until research and the theory of today, design the layout of carrier pipe statically and design based on the calculating to average situation.Usually, do not consider that basically other flows or trial come it is compensated by other means and approach.
DE 102 26 820 B3 have described a kind of a plurality of bending delivery pipes that have, and wherein make this fibre stream be close to a side of carrier pipe and spray from offside by deflected fibers stream.
DE 100 59 881 A1 have pointed out a kind of equipment with the fiber preprocessing, and wherein the gluing zone has sleeve pipe, wherein impact through the outside of the interior pipe of punching with compressed air, are bonded on the inner tubal wall to prevent fiber.
DE 102 47 412 A1 have pointed out that equally the cross section before gluing changes, wherein at fiber before falling into the whereabouts vertical shaft, additionally locate these fibers towards the direction of paste nozzle by dividing plate.
From practice, know, with higher steam input compensate material in the carrier pipe than low discharge.For this reason, the additional steam pipeline is installed, under the situation of low discharge, is loaded these additional steam pipelines with additional steam at the correct position place of carrier pipe.Only can increase quantity of steam by fibrosis machine or steam cooker itself, because the discharge of steam that increases works to the pressure in digestion time and the steam cooker once more limitedly.Equally, these possibilities no longer can be carried out in the epoch of today economically, because the energy cost of per time unit can not be brought income and corresponding environment compatibility problem meanwhile occur.
Summary of the invention
Therefore, task of the present invention is, a kind of method and a kind of equipment that is used for operating equipment is provided, utilizes this equipment under the situation of the different flow of per time unit, to realize the optimum gluing of fiber and with binding agent the gluing that fiber carries out is satisfied high request simultaneously.At this, also should provide method and apparatus, can mate at the production interval of run duration by it.
The solution that is used for the method for operating equipment is, for the different flow that mates fiber or for maintenance purpose, change the characteristic of at least a portion transportation section, wherein this change is so carried out, so that at least a portion of changing between at least two carrier pipes and/or replace carrier pipe with at least one second carrier pipe by at least one switching device.
According to the present invention, the solution that is used for equipment is that in order to change the characteristic of transportation section, at least a portion of this transportation section comprises at least two carrier pipes, wherein, in this transportation section, arrange at least one switching device (4) and/or at least one flange for these carrier pipes of conversion ground control.
With regard to concept nature, the characteristic of the said carrier pipe of the present invention is meant the structure type that needn't always be embodied as the carrier pipe of constant aspect internal diameter.Range of geometrical variations about the internal diameter of this type of carrier pipe is disclosed in the example of prior art in a large number.Principle of the present invention is pointed out, the characteristic of carrier pipe can be complementary with corresponding production in safeguarding situation and/or when producing conversion.For this reason, can conceive next described possibility.Described equipment itself be can operate separately and itself demonstrate favourable feature, but also be applicable to the described method of carrying out certainly especially.Notion " transportation section " is illustrated at this and is used for making the conveying of the equipment of fiberboard to fiber, and wherein this conveying is preferably from defibrator (steam cooker) or fibrosis machine begins and preferably be admitted to tube drier.Preferably, the material to fiber or like fibrous carries out gluing in this transportation section.
Advantageously, the present invention has solved the problem of a difficulty for the equipment network operator.Because by the present invention, the equipment network operator can accept now no problemly little order or even critical order, these orders will come work with the requirement to the limit of reliability of production equipment and therefore propose challenge to raw-material than high flow rate.By simple, with low cost and solution allow to be provided as immediately the remodeling solution on market, traditional equipment has been expanded at least a portion or whole carrier pipe, expands to tube drier from fibrosis machine in the present embodiment.Therefore, under the situation that the fiber flow with per time unit is complementary, always can select to be best suited for the carrier pipe of this flow and this carrier pipe is incorporated in the production equipment.By test, calculating or model, the network operator learn which kind of bore of carrier pipe or geometry be best suited for just have purpose to be solved and in case of necessity in addition automation ground select this bore or geometry.For this reason, at first carry out calculating about the steam consumption and the fiber flow of fibrosis machine (refiner) in conjunction with internal diameter.Certainly, also can be enduringly monitor this production part, and can automatically point out that to network operator or Machine Operator the conversion between these carrier pipes is significant or indispensable under the situation of continual level difference measurements with measurement mechanism (gum consumption of the speedometer in the carrier pipe, binding agent nozzle, or the like).
Advantageously, with all parts that interchangeable mode is arranged carrier pipe, these parts may be made dirty termly and must correspondingly be cleaned in the maintenance area.In addition, wearing and tearing in long its interior zone of pipe testing of logarithm rice or bonding also can not in minutes execute, but need manpower and equipment.Conversion between the carrier pipe can be manually brought in execution by the connection of replacing two fixing (the most nearly 100 meters) long carrier pipes, and perhaps the part of carrier pipe is replaced and connect this part with suitable sealable flange.In expensive embodiment, can be by switching device, preferred even at production period, carry out this conversion.
Must be noted that in the case importantly between two carrier pipes or the conversion between its all part, the carrier pipe that wherein is replaced also should have different inside and/or external shape according to application purpose on its length, so that optimize gluing.Can also conceive and use identical carrier pipe, need only the wearing and tearing or the bonding of the increase that must check termly, monitor and/or clean in the appearance of certain device point place.

The specific embodiment
According to Fig. 1, exemplary and simplify shown in manufacture process start from defibrator 1, it also is called as fibrosis machine, this defibrator 1 by overvoltage and vapor action by to timber, wood chip or similarly raw-material hot mechanical fiberization make fibrous material or fiber 20.By transportation section 22 these fibers 20 are sent into carrier pipe 2 (in the industry or professional notion to those skilled in the art: " blow line (Blow-Line) ") and with one or more paste nozzles (not shown in Fig. 1) these fibers 20 are carried out gluing during being carried.Subsequently, with the speed higher fiber 20 is introduced tube drier 3 than the prevailing air velocity of drier air 6.The necessary air velocity for conveying of the drier air 6 in the tube drier 3 produces by air blast 12, and this air blast 12 is supplied with through dry air heating (about 180 ℃～220 ℃) and preferred.After being 100 meters tube drier 3 at most, the fiber of drying is admitted to cyclone separator 14, and this cyclone separator 14 is separated drier air 6 and fiber 20 and the drier air 6 that will have dust content is to a certain degree in case of necessity sent into prefilter 16.Subsequently, in the waste gas purification apparatus 17 of heat, drier air 6 is carried out post processing and it is discharged in the environment.The fiber of drying then is admitted to fiber feed bin 8 and is dumped in the laying device 10 slab that this laying device 10 is mated formation and is made of the fiber 20 through gluing and drying therefrom controllably on forming belt 7 by impeller gate 15 in cyclone separator 14.Subsequently, slab is admitted to continuous operation formula or intermittent working type press 11 and it is sent into the zone of after-treatment device 18 after slab is pressed into fiberboard.In after-treatment device, these fiberboards of correspondingly cutting, grinding and placement.
If after high density fiberboard, only produce now medium density fibre board (MDF) or even light-duty fiberboard, then current processing procedure need generally still less fibrous material and fiber 20 that will be still less be dumped into the carrier pipe 2 from defibrator 1.Rule of thumb, but equipment so far only optimally work in certain zone and for more uncommon working region usually aspect the gluing only suboptimum ground regulate.Now, in order optimally to regulate these zones equally, especially with regard to transporting velocity and gluing quality, change switching device 4 and load first carrier pipe 2 with fiber 20 no longer continuously, but activate second carrier pipe 9 that has the nozzle 5 that is used for gluing equally according to Fig. 2.It will be appreciated by those skilled in the art that and not only can use two different carrier pipes 2,9, according to using a large amount of carrier pipes with the harmonious of application scenario.Even can also conceive unit equipment, this unit equipment also uses plastic hybrid or other substitutes and needs special carrier pipe to carry out gluing for this reason except the material that uses fiber or like fibrous.In a particularly preferred situation, there are three different carrier pipes, they are respectively applied for low fiber flow, medium (common) fiber flow and high fiber flow.Under lower fiber flow situation, equally less steam is transferred to the transportation section 22 from defibrator 1.Can recognize herein, compare with the situation of per time unit big fiber flow, it is significant using narrower carrier pipe under the situation of per time unit's fubril flow, because stopping up and making significant gluing become impossible simultaneously may appear in narrow carrier pipe.Simultaneously, it also is disadvantageous using excessive carrier pipe under the situation of a large amount of fibers of per time unit, because do not reach necessary transporting velocity for the gluing of optimum by very few steam.As described, in view of environmental problem and high cost of energy, additionally steam being imported carrier pipe is not the alternative that is worth expectation.Those skilled in the art can adjust the present invention up hill and dale about selecting on speech " less " and " bigger " this point, because the size of carrier pipe is also represented transporting velocity and the material type standard expected, these all need deep calculating, and these calculating then are equipment builder's task scopes.
In principle, the further part of described method is its common process, and fiber 20 remainder by first carrier pipe 2 after being gummed is admitted to tube drier 3, and transfers these fibers 20 in the tube drier 3 drier air 6 with at least one discharge nozzle 19.
According to Fig. 3, as get off to revise this process: after first switching device 4, do not have other switching device, and two carrier pipes 2 and 9 have two that separate, as to be used for fiber 20 is transferred to drier air 6 discharge nozzles 19 in tube drier.For this embodiment, need two groups of nozzles 5 equally herein, designed because nozzle 5 is respectively corresponding carrier pipe 2 or 9.In Fig. 2 and 3, can also see starting pipe (Anfahrrohr) 13.That this pipe is used for going on business in start-up function letter sorting or underproof fiber and prevent that these fibers from entering production process.This improves thinks this type of starting carrier pipe according to carrier pipe of the present invention, is to be used for purpose that fibrous material is rejected from processing procedure because this starting carrier pipe does not enter tube drier 3 or its.
Fig. 4 shows the simple solution according to task of the present invention, and this solution helps to retrofit or be used for narrow structure space especially.As required, second carrier pipe 9 is inserted the characteristic that carrier pipe 2 and this second carrier pipe 9 have the replaced part that is different from carrier pipe 2 at least in part, for example different internal diameters.Because the little external diameter of these carrier pipes, the flange solution of utilizing flange 21 is no problem in principle.But, can also carry out the connection and the sealing of the flange 21 of carrier pipe 2,9 in automation ground, as long as have demand or hope to this.Omitted diagram solution herein to this type of standard element.Those skilled in the art take measures necessary at this, so that set up such being connected according to prior art reliably with technical regulation.
In another replacement solution according to Fig. 5, equipment or defibrator 1 directly have three outlets, wherein can change between these outlets as required.Introduced starting pipe 13 equally herein.For the number of the nozzle 5 in the optimization equipment also, further be recommended in the first area of carrier pipe 2 and arrange these nozzles 5.Make progress at producer, just substitute the part of first carrier pipe 2 after this as required with carrier pipe 9.The observer can understand, and also can conceive other possibilities within the scope of the invention, so as to realize or design as far as possible inexpensively transportation section 22 whole carrier pipe 2 all parts or transportation section 22 according to replacement of the present invention.
With regard to employed nozzle, should be noted that, described equipment or method are applicable to paste nozzle extremely well, and these paste nozzles disperseed binding agent and/or in the mode of pulverizing this binding agent with steam it sent into carrier pipe at binding agent when nozzle is discharged with steam before binding agent enters carrier pipe.Therefore in these two kinds of nozzles, steam is used to binder decomposed to less than in 40 microns the scope and realize optimum gluing to fiber when it is sprayed into carrier pipe.These nozzles are particularly suitable to this, because can be when in mixing chamber, disperseing binding agent, but in carrier pipe, then need the minimum speed to a certain degree of fiber or steam before the nozzle itself or optimally carry out pressure before entering blow line and regulate to this dispersion with steam.If do not reach this minimum speed now, the gluing quality can descend once more equally and must additionally add steam so.In the broken nozzle of conducting powder, momently or the steam impringement that during binding agent enters carrier pipe, arrives at side direction pulverize binding agent and so this binding agent introduced carrier pipe.Herein additionally the input small amount of steam be have surplus and only for break up or hybrid adhesive for be necessary.
