Description
Technical field
The present invention relates to a kind of method for operating equipment, this equipment is used for manufacturing fiberboard, MDF, HDF, composite wood boards or plastic plate with fiber or similar fiber.In addition, the invention still further relates to this kind of equipment.
Background technology
The manufacture 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 in a continuous manner the wood chip after preprocessing or fiber is suppressed.But except have many units before and after press except, what play a crucial role is to manufacture slab by spreading machine; Except the quality of raw material, the quality of made slab is also a key factor.When large-scale industry manufactures composite wood boards, use continuously operating press, but partly also use lamina or multi-layer sheet press.Pursue and carry out the cheap plate of material of manufacturing price with natural raw material and artificial binding agent, force manufacturers to go to develop more and more high efficiency method.In the case, focus on quality especially to remain unchanged energy cost in situation, conservation of raw material and binding agent saving and there is the device structure technically through optimizing of few downtime and low wearing and tearing.In principle, binding agent refers to so-called glue, and the key component of this glue comprises adhesive.As required, emulsion, curing agent, formaldehyde scavenger, colouring agent, desinsection and bactericide and other additives is additionally added.Usually the adhesive not having additive is also used.Do not attempt exhaustive, as binding agent can be: isocyanates (MDI), melamine urea formaldehyde (MUF), urea-formaldehyde (UF), MUPF or PF.
These wood chips have usually been supplied as wood chip or have been manufactured at the scene and be conveyed to gluing before the drying or afterwards.Fiber be then manufactured at the scene by fiberization equipment and be transported to drier by carrier pipe after the fibrillatable of carrying out between two mills.When decomposing fiber by steam cooker, unnecessary steam is used to drive these fibers to pass through carrier pipe.According to instrument size and device structure, carrier pipe can have the length of the most nearly 100 meters.Preferred with the relatively little pipe of supersonic speed at little internal diameter in during the conveying that performs, fiber is gummed and is admitted to drier subsequently.Large challenge can be produced when carrying out high pressure gluing in carrier pipe, extremely rapid have 7 × 10 because there will be
5to 3 × 10
6the flowing of Reynolds number (Reynoldszahl).In the case, the speed of fiber at least 50m/s until fluctuate in the scope of the speed of 474m/s.Subsequently, these wood chips or fiber usually dried, be placed in feed bin, mated formation quantitatively is pressed into plate of material to base plate and by press.
So far, introduce carrier pipe to carry out the necessary binding agent nozzle of gluing, these nozzles so break up this binding agent, with make preferably with the size in the micrometer range of long number to spray into this binding agent.Utilize so-called atomization (pressure) nozzle binding agent roughly can be decomposed the size of 100 to 40 microns.But, for this reason necessary, use the high pressure nozzle breaing up the binding agent at nozzle head place by the step-down in another pressure span to work together.Up-to-date research and development has indicated the new way about spraying possibility, wherein when binding agent is discharged or in nozzle, by steam, this binding agent is dispersed as molecule.In the case, the little drop size of above-mentioned 40 microns of binding agent can be reduced again the most nearly 20 microns.For rapid fibre high-speed flowing in binding agent Optimal Distribution for, urgently preferred binding agent is dispersed as minimum.
When fiberboard manufactures, fibrous material is admitted to drier and dried during gluing or after gluing, is admitted to tube drier in a preferred embodiment and dried.In order to drier air and dried fibrous material are separated, usual use cyclone separator, being defined in prefilter to purify and usually being burnt this drier air as waste gas subsequently by the drier air made dirty wherein according to necessity or Environmental Technology aspect.Method used in the case is known and is implemented in the device being called as " RTO=heat accumulating type heating power incinerator ".After cyclone separator, dried fibrous material to be placed in feed bin and to be discharged into paving station as required, and this paving station, on the forming belt of motion continuously, fibrous material is configured as slab and this fibrous material is carried in direction towards press.Usually, after precompressed or pretreatment are carried out to slab, this slab is sent into continuously operating press and by pressure and heat, this slab is pressed into plate of material.Effects on surface carries out flat surface grinding and is cut into pre-sizing with destacking subsequently after pressing.
Nowadays, the network operator of fiber manufacturing apparatus will thank to little order, to guarantee to make full use of the production in 24/7 cycle.Therefore, several hours or even within more than several days, to run identical product type be no longer common always, but repeatedly to change production thickness and/or the production density of the plate of material wanting manufactured every day.This means, the flow of fiber in carrier pipe matches with the required amount through rubberized material regularly.
Until generation raw material crises, effectively and in carrier pipe, to perform gluing with saving material be unessential whether, this is especially all the more so in rare little surplus situation.As described, this situation there occurs marked change, and equipment network operator wishes to realize optimum for all types of flow and is first the gluing saved.So far, the optimization of gluing is controlled by the pressure of binding agent that will be injected equally, and in the case, larger flow of material corresponds to high pressure, and less flow of material corresponds to lower pressure.This is also associated with following situation: the injection cone of binding agent contacts Face to face in inner radius, binding agent clings there and forms 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 in the flow of material situation of change.For saving binding agent or such as can finding in DE1632450A1 for other solutions optimally binding agent is coated in carrier pipe on the fiber in motion; It discloses a kind of for continuously tiny component relatively in a small amount and the carrier material by air motion being carried out the device mixed.In this publication, in carrier pipe, do not use steam and be only applicable to very little flow.Mentioned herein go out solution be, neatly carrier pipe be designed to all parts and process this carrier pipe with percussion mechanism if desired, would not bonding be formed thus.In addition, also propose rotate this carrier pipe or enduringly this carrier pipe be divided into multiple carrier pipe simultaneously.Wherein, only used static solution herein and do not arrange and the mating of flow.
DE19506353A1 indicates a kind of method and apparatus for soaking with fluid, and the change of cross section targetedly that the method and device are attempted by carrier pipe in jeting area improves gluing result.In the case, before nozzle, preferably reduce the diameter of carrier pipe, to increase the turbulent flow in Mixed Zone.With different flow to mate at this be realized by the project organization of nozzle, but its to be proved to be in practice be not optimum.
After this several years are until the research of today and theory show, design the layout of carrier pipe statically and design based on to the calculating of average case.Usually, substantially do not consider other flows or attempt being compensated it by other means and approach.
DE10226820B3 describes a kind ofly has multiple bending carrier pipe, wherein makes this fibre stream be close to the side of carrier pipe and spray from offside by deflected fibers stream.
DE10059881A1 indicates a kind of equipment of fiber preprocessing, and wherein glue bearing areas has sleeve pipe, wherein impacts the outside of pipe in punching with compressed air, is bonded on inner tubal wall to prevent fiber.
DE10247412A1 indicates that cross section before gluing changes equally, wherein at fiber to before falling into whereabouts vertical shaft, locate these fibers additionally by division plate towards the direction of paste nozzle.
Know from practice, compensate the comparatively low discharge of the material in carrier pipe with the input of higher steam.For this reason, at the correct position place of carrier pipe, additional steam pipeline is installed, loads these additional steam pipelines when low discharge with additional steam.Only limitedly quantity of steam can be increased, because the discharge of steam increased works to the pressure in digestion time and steam cooker again by fibrosis machine or steam cooker itself.Equally, these possibilities no longer can perform economically in the epoch of today, because the energy cost of per time unit can not bring income and meanwhile occur corresponding environmental compatible sex chromosome mosaicism.
Summary of the invention
Therefore, task of the present invention is, a kind of method for operating equipment and a kind of equipment are provided, utilize this equipment to realize the optimum gluing of fiber when the flow that per time unit is different and to meet high request with binding agent to the gluing that fiber carries out simultaneously.At this, also should supplying method and equipment, can be mated at the production interval of run duration by it.
Solution for the method for operating equipment is, in order to mate fiber different flow or in order to maintenance purpose, change the characteristic of transportation section at least partially, wherein this change is so carried out, to make to carry out changing and/or replacing carrier pipe at least partially with at least one second carrier pipe between at least two carrier pipes by least one switching device.
According to the present invention, solution for equipment is, in order to change the characteristic of transportation section, this transportation section comprise at least two carrier pipes at least partially, wherein in order to control these carrier pipes in conversion, in this transportation section, arrange at least one switching device (4) and/or at least one flange.
With regard to conceptual, the characteristic of the said carrier pipe of the present invention refers to the structure type that always need not be embodied as the carrier pipe of constant in internal diameter.Disclose in the example of prior art in a large number about the range of geometrical variations of the internal diameter of this type of carrier pipe.Principle of the present invention is pointed out, to safeguard in situation and/or the characteristic of carrier pipe and corresponding production can matched when producing conversion.For this reason, next described possibility can be conceived.Described equipment itself be can operate separately and itself demonstrate favourable feature, but certainly be also applicable to especially perform described method.Concept " transportation section " represents the conveying to fiber in for the manufacture of the equipment of fiberboard at this, and wherein this conveying is preferably preferably admitted to tube drier from defibrator (steam cooker) or fibrosis machine.Preferably, in this transportation section, gluing is carried out to the material of fiber or like fibrous.
Advantageously, the present invention is that equipment network operator solves a difficult problem.Because by the present invention, equipment network operator can accept little order or even critical order now, and these orders will carry out work with the requirement of the limit of reliability to production equipment and therefore propose challenge to raw-material comparatively high flow rate no problemly.By simple, with low cost and allow the solution being commercially provided as remodeling solution immediately, traditional equipment is expanded at least partially or whole carrier pipe, expands to tube drier in the present embodiment from fibrosis machine.Therefore, when the fiber flows match with per time unit, always can select to be best suited for the carrier pipe of this flow and this carrier pipe is incorporated in production equipment.By test, calculate or model, network operator learns which kind of bore of carrier pipe or geometry are best suited for and just have object to be solved and even automatically select this bore or geometry if desired.For this reason, the calculating of steam consumption about fibrosis machine (refiner) and fiber flow is first performed in conjunction with internal diameter.Certainly, also can monitor this production part with the measurement mechanism gum consumption of the speedometer in carrier pipe, the binding agent nozzle (, etc.) enduringly, and automatically can point out that the conversion between these carrier pipes is significant or indispensable to network operator or Machine Operator when continual level difference measurements.
In maintenance area advantageously, arrange all parts of carrier pipe in interchangeable mode, these parts may be made dirty termly and must correspondingly be cleaned.In addition, the wearing and tearing in its interior zone of pipe testing that logarithm rice is long or bonding also can not in minutes execute, but need manpower and equipment.Conversion between carrier pipe can manually be performed by the link of fixing (the most nearly 100 meters) the long carrier pipe of replacement two, or a part for carrier pipe is replaced and connect this part with suitable sealable flange.In embodiment costly, by switching device, preferably even at production period, this conversion can be performed.
Must be noted that in the case, the conversion importantly between two carrier pipes or between its all part, the carrier pipe be wherein replaced also should have different inside and/or external shape, to optimize gluing over its length according to application purpose.The carrier pipe that all right conception practice is identical, as long as the wearing and tearing or the bonding that occur the increase must checked termly, monitor and/or clean at certain equipment point place.

Detailed description of the invention
According to Fig. 1, exemplary and the manufacture process shown in simplification starts from defibrator 1, it is also called as fibrosis machine, this defibrator 1 by overvoltage and vapor action by manufacturing fibrous material or fiber 20 to timber, wood chip or similar raw-material thermomechanical fibrillatable.These fibers 20 are sent into professional conceptual in carrier pipe 2(industry or to those skilled in the art by transportation section 22: " blow line (Blow-Line) ") and with one or more paste nozzle (not shown in FIG), gluing is carried out to these fibers 20 during carrying.Subsequently, with the speed that the prevailing air velocity than drier air 6 is higher, fiber 20 is introduced tube drier 3.The necessary air velocity for conveying of the drier air 6 in tube drier 3 is produced by air blast 12, this air blast 12 be supplied with through heating (about 180 DEG C ~ 220 DEG C) and preferably dry air.After the tube drier 3 being at most 100 meters, the fiber of drying is admitted to cyclone separator 14, and this cyclone separator 14 makes drier air 6 and fiber 20 separate and the drier air 6 if desired with dust content is to a certain degree sent into prefilter 16.Subsequently, in the waste gas purification apparatus 17 of heat, drier air 6 is carried out post processing and is discharged in environment.The fiber of drying is then admitted to fiber feed bin 8 by impeller gate 15 and is dumped into controllably therefrom in laying device 10 in cyclone separator 14, and this laying device 10 is mated formation by through gluing and the slab that forms of the fiber 20 of drying on forming belt 7.Subsequently, slab is admitted to continuously operated or intermittent working type press 11 and after slab is pressed into fiberboard, is sent into the region of after-treatment device 18.In after-treatment device, these fiberboards of correspondingly cutting, grinding and placement.
If only produce medium density fibre board (MDF) or even light-duty fiberboard now after high density fiberboard, then current processing procedure needs less fibrous material generally and is dumped into carrier pipe 2 from defibrator 1 by less fiber 20.Rule of thumb, equipment so far only optimally works and usually only can regulate in gluing for more uncommon working region suboptimum in certain region.Now, in order to optimally regulate these regions equally, especially with regard to transporting velocity and gluing quality, change switching device 4 according to Fig. 2 and no longer continuation fiber 20 loads the first carrier pipe 2, but activate the second carrier pipe 9 of the nozzle 5 had equally for gluing.It will be appreciated by those skilled in the art that and not only can apply two different carrier pipes 2,9, a large amount of carrier pipe can be used according to 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 using the material of fiber or like fibrous.In a particularly preferred situation, there are three different carrier pipes, they are respectively used to low fiber flow, medium (common) fiber flow and high microsteping flow.Under lower fiber traffic conditions, equally less steam is transferred to transportation section 22 from defibrator 1.Can recognize herein, compared with the situation of the large fiber flow of per time unit, narrower carrier pipe is used to be significant when per time unit's fubril flow, because narrow carrier pipe may occur blocking and make significant gluing become impossible simultaneously.Meanwhile, excessive carrier pipe is used also to be disadvantageous when a large amount of fiber 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 being worth expecting.Those skilled in the art can adjust the present invention up hill and dale about selecting in word " less " and " larger " this point, because the size of carrier pipe also represents transporting velocity and the material type standard of expectation, these all need deep calculating, and these calculating are then the task scopes of equipment builder.
In principle, the further part of described method is its common process, and fiber 20 is admitted to tube drier 3 by the remainder of the first carrier pipe 2 after being gummed, and with at least one discharge nozzle 19 these fibers 20 are transferred to the drier air 6 in tube drier 3.
According to Fig. 3, revise this process as follows: the switching device that there are not other after the first switching device 4, and two carrier pipes 2 and 9 have in tube drier two that separate, for fiber 20 being transferred to the discharge nozzle 19 of drier air 6.Needs two groups of nozzles 5 for this embodiment equally herein, because nozzle 5 is respectively designed by corresponding carrier pipe 2 or 9.Can also see in figs 2 and 3 and start pipe (Anfahrrohr) 13.This pipe is used for sorting in start-up function is gone on business or underproof fiber and prevent these fibers from entering production process.This improves and this type of is not started carrier pipe and does not think according to carrier pipe of the present invention, because this starting carrier pipe does not enter tube drier 3 or it is object for being rejected from processing procedure by fibrous material.
Fig. 4 shows the simple solution according to task of the present invention, and this solution contributes to carrying out retrofiting or for narrow structure space especially.As required, the second carrier pipe 9 is inserted carrier pipe 2 and this second carrier pipe 9 has the characteristic of the replaced part being different from carrier pipe 2, such as different internal diameters at least in part.Due to the little external diameter of these carrier pipes, the flange solution of flange 21 is utilized to be no problem in principle.But, automatically can also perform connection and the sealing of the flange 21 of carrier pipe 2,9, as long as the demand existed this or hope.Explanations are omitted here the diagram solution to this type of standard element.Those skilled in the art take necessary measure, reliably to set up such connection according to prior art and technical regulation at this.
Replacing in solution according to another of Fig. 5, equipment or defibrator 1 directly have three outlets, wherein can change between these export as required.Introduce equally herein and start pipe 13.In order to go back the number of the nozzle 5 in optimized device, being recommended in further in the first area of carrier pipe 2 and arranging these nozzles 5.On production mode reform, just carry out a part for alternative first carrier pipe 2 after this as required with carrier pipe 9.Observer can understand, within the scope of the invention also it is conceivable that other possibilities so that realize or as far as possible inexpensively design transportation section 22 all parts or transportation section 22 whole carrier pipe 2 according to replacement of the present invention.
Should be noted that with regard to used nozzle, described equipment or method are applicable to paste nozzle extremely well, and these paste nozzles disperseed binding agent with steam and/or sent into carrier pipe when binding agent is discharged from nozzle in the mode pulverizing this binding agent with steam before binding agent enters carrier pipe.In these two kinds of nozzles, steam is used in binder decomposed to the scope being less than 40 microns and the optimum gluing therefore realized when spraying into carrier pipe fiber.These nozzles are particularly suitable to this, because disperse optimally to carry out pressure adjustment to this dispersion before nozzle itself or before entering blow line during binding agent with steam in mixing chamber, but then need the minimum speed to a certain degree of fiber or steam in carrier pipe.If do not reach now this minimum speed, so gluing quality again can decline equally and additionally must add steam.In the nozzle that conducting powder is broken, momently or during binding agent enters carrier pipe with the steam impringement that side direction arrives at, pulverize binding agent and so this binding agent is introduced carrier pipe.Herein attachedly a small amount of steam inputted have surplus and only for breaing up or being necessary for hybrid adhesive.
