Abstract
The present invention relates to a method for continuously manufacturing the composite wood product board with the continuous running press. The invention rests with in the condition that the pulling forward speed of the pressurizing object pad in the continuous running press is rapidly reduced to a determined value until to zero, the importing of the heating medium imported to the heating plate with temperature below 200 DEG C is stopped, and a heating medium with temperature below 200 DEG C (preferably below 100 DEG C) is leaded in to cool the heating plate. The continuous-running press runs in this way in order that the heating plate is filled with the hot or cold medium selectively.
Description
Technical field
The present invention relates to a kind of method of continuous manufacturing such as clamping plate, fiberboard or suchlike composite wood sheet of the preamble according to claim 1, also relate to a kind of press of according to claim 14, the continuous operation that is used for implementing this method.
Background technology
At present in the press of operation continuously during compression combined timber-work pad the highest applied temperature of heating plate be 250 ℃.In order to realize improving press speed, except the measure as the pad preheating, also can further improve the temperature of heating plate.One temperature of heating plate that the has improved front area of press (mainly) makes the steel band of porch and the circulating element (scroll bar, chain) be able to rapid heating, reaches a higher temperature of steel strips after several meters press length.By heating steel band apace and reaching higher temperature levels thus, can shorten heat time heating time, the elapsed time that promptly reaches 100 ℃ in the middle part of the pad can shorten.In addition, in the type of some plate, also can further heighten the middle temperature levels of pad, thus, will shorten the hardening time of binding agent (wherein, using MDI or condensation resin mostly).Two kinds of effects cause the shortening of press working time, thus, improve the production capacity of equipment.
But so far temperature of heating plate is brought up to various trials more than 250 ℃ owing to multiple reason all fails.Chief reason is the danger that the composite wood goods pad burning in the press itself causes.In the multi-layer sheet press, can adjust the maximum heating plate temperature according to danger of combustion is 230 ℃.Exist such danger more than the temperature at 220 ℃, i.e. lignocellulosic spontaneous combustion and under the situation that oxygen adds, taking fire, wherein, because the danger of the rising of temperature aggravation spontaneous combustion.Under the situation that production stops (for example, emergency operation causes), thus, when temperature of heating plate surpassed 250 ℃, very fast the appearance in press burnt, and surpasses about 220 ℃ autoignition temperature because pad is heated to.In addition, by the high steam pressure (being caused by high temperature) in the plate, the part plate can eject from press, and spinner member (Umlaufelement) is damaged.
Another reason of restriction temperature of heating plate is the harm that burning causes, burning causes the pollution to heating plate.Show that in addition the production under higher temperature of heating plate is responsive for the reaction of the moisture fluctuation in the pad.
The lubricated of spinner member realized with lubricating oil, and lubricating oil can decompose more than 250 ℃ and the aggravation evaporation.In general, scroll bar is implemented lubricated consumption, and it causes, and lubricating oil separates with scroll bar with steel band through press nips after the operation of press article pad.If very little or have only the lubricating oil of cracking to be present on the scroll bar in the press nips, then can causing, lubricating oil damages scroll bar or steel band.In other words, it is destroyed that the temperature of introducing in the scroll bar spreading area must stop oil.Yet this also is not able to success fully in the biobelt press that exists at present.
Summary of the invention
Task of the present invention is to provide a kind of method, do not have danger of combustion when under higher temperature of heating plate, pressurizeing, can not damage spinner member and steel band by this method composite wood goods pad, and the rate of can reducing the number of rejects and seconds, therefore, help improving the production capacity of equipment.
According to claim 1, the solution of this task is: the speed that pushes away before pressurization article pad reduces a determined value rapidly in the situation that is tending towards stopping, the introducing that adds heat medium that is incorporated into heating plate is stopped, and import one in the temperature below 200 ℃ (preferably below 100 ℃) in case the cooling heating plate.
Composite wood goods pad pushes away before can often occurring stopping, and takes place repeatedly in the week, and for example, scroll bar moves consumingly, the termination of emergency operation, press overvoltage, the regional inner sensor of shaping bar, pushes away to stop before the removal of stacking etc. all can cause.
For can make production according to the present invention before several seconds, pushed away in the situation that stops or under certain determined value before push away in the situation that is reduced to 40mm/sec the burning that plate does not take place after pressurization neutralization pressurization, need to implement in the following manner heating.The heating power fuel tap door more than 260 ℃ that is used in advance flowing is promptly closed, and cold heating power oil is incorporated in the heating plate, and heating plate is cooled to below 230 ℃ thus, wherein, implements such adjusting: lasting 5 minutes to 20 seconds of cool time.At this moment, the heating power oil from storage bin of temperature at (preferably below 100 ℃) below 200 ℃ partly is incorporated in the heating plate, or the deep fat in the circulation cools off by a heat exchanger.Prove thus press after heating plate is cooled to below 240 ℃ just release be favourable.If release immediately after stopping, then the oxygen of Zeng Jiaing can pour on the already heated plate, and increases the danger of burning in the process of heating plate cooling.
Introduce temperature in the heat medium that adds more than 260 ℃ if reduce this moment, and when the pad ejection is opened, further advantage is arranged then.Thus, can shorten the dead point time of adjustable range, and reduce the adjusting deviation of temperature of heating plate offrating.
In order further to reduce danger of combustion, only forwardly heat with very high temperature of heating plate in the zone, during with clearancen (Entleerung) press under stopping of producing and pressure, obtain cooling off by cooling back heating plate.If latter two heating plate has the temperature below 100 ℃, then has advantage this moment especially.Thus, not only reduce the danger of burning, and at first in the surface layer zone of plate, reduced the danger that waste product is produced by Platzer.The cooling on the plate surface in the cooling of steel band and the press that brings thus causes the cohesion of steam in the plate, thus, causes the decline of steam pressure in pad.
In the situation that can occur lubricating oil excessive vaporization and lubricating oil cracking more than 250 ℃ during temperature intensely, in order to limit the appearance of this situation, similarly taked many with more than enumerate consistent measure (near developed surface (Abrollflache) with reduce temperature of heating plate on a sensor adjustment temperature of heating plate, the length at press, when stopping the cooling heating plate or reduce before push away).The cooling of heating plate obviously causes can not being damaged at press clearancen steel band in service and spinner member during the operation of press clearancen when stopping and thereafter.If heating plate is not cooled, then in the almost cracking or the evaporation of clearancen whole lubricating oil in service of press thereafter, so that all the other zones in the press do not have lubricatedly, this is not having going out in the dry running (Leerfahren) of pressure to cause damaging press.
Temperature of heating plate that can classification carries out work, because the temperature of the temperature of scroll bar and lubricating oil obviously is lower than the temperature of heating plate when press begins, so, although temperature of heating plate has improved, the cracking of lubricating oil can not appear.In the back region of press, temperature of heating plate is reduced to the temperature near lubricating oil cracking point, because steel band and scroll bar obviously heat lessly near temperature of heating plate and fill up in this zone.Because temperature of heating plate descends, and on whole press length, almost produces the lubricating oil temperature of maximum possible.
Also being used as the temperature of in advance moving controlling value answers the place of as close as possible consumption of calorie to measure.In other words, for example, in the temperature of heating plate of 270 ℃ (measuring near developed surface), the running temperature in advance of heating power oil reaches 290 ℃ when entering heating plate; And have only 260 ℃ in the expansion edges and corners, and in the spreading area of scroll bar, be about 255 ℃, be 290 ℃ on the opposite side of heating plate.Current when pushing away speed and reducing, less from the heat that product is taken away, the temperature in the filler zone rises immediately, and valve is closed immediately.Add heat medium introduce close after, the temperature of heating plate on the side relative with scroll bar descends, because colder heating plate is heated.If filler is the hot side that 50mm or 70mm--are positioned at heating plate from developed surface, and if the speed that reduces of equipment can not discern soon so that also heating unceasingly, but it is removed to no longer include heat from product.Thus, the cracking of lubricating oil is dangerous and rise by the danger that the waste product that Platzer causes is produced.By regulate also can be as much as possible near the cracking temperature of lubricating oil.
Regulate in conjunction with the pressure of press by highstrung adjustment, in the surface layer zone, can avoid the danger of waste product production by Platzer according to superheated.Pressurize with high press speed and high temperature of heating plate, react on the face weight fluctuation (Flachengewichtschwankung) of pad moisture fluctuation (Mattenfeuchteschwankung), pad and the fluctuation of pad endoparticle size (Partikelabmessung) very sensitively, because the hardening time of glue is very short, and three parameters are for having hardening time of heat time heating time and pad thus very big influence.Heating by moisture fluctuation or face weight fluctuation pad needs to change at short notice, wherein, adjustment by sensitivity, although the requirement of heating has changed but the temperature of heating plate does not change, although and the requirement of heating thus or high or low and speed press can keep constant, reduce the danger that waste product is produced.Also advantageously: press nips mainly (at first in entering the zone) is adjusted according to a pressure ratio, because change intensely when above-mentioned three fluctuations are not adjusted as press nips at the pad center in the constant compression force ratio of hot-fluid.Prove and particularly advantageously be: comprising that the temperature of heating plate that uses a tandem under the situation that acts on the pad humidity that records on the forming belt (Formband) regulates, so that adjust the heat request that adds of variation early by moisture fluctuation.
The boring that is used to add heat medium should as close as possible developed surface, thus, can cool off developed surface quickly when stopping, and the adjustment of temperature of heating plate accurately can be remained on the setting.
By the cooling in several seconds so that to the shortening of the heating of heating plate must be unstressed as far as possible, and this can be solved by the motion of whole frame on the scroll wheel part.
