Technical field
The present invention relates to a kind of in the process of producing composite wood boards such as particieboard, fiberboard the method for compacting and pressing and hardening cushions.
Background technology
As everyone knows, in the process of producing composite wood boards, continuous compacting backing strap introducing is had in the continuous press that pushes the continuous operation that constitutes top clearance between the steel band, and this compacting backing strap is by the standard of the extruding force curve of being scheduled to and the standard compression and the sclerosis of pressing predetermined temperature curve.In order to guarantee to need not to worry when leaving top clearance, to influence product quality owing to finish the internal vapor pressure of the composite wood boards of compacting, the compacting backing strap is removed the steam dome at it by introduce one in the path of top clearance behind the sintering, in this zone, extruding force is reduced in such a way, that is, can reach enough removal steam.Can be processed with the compacting backing strap of relatively wetter surface layer thus.Can improve forcing press production capacity (seeing DE3825819C2) in addition.
The method of composite wood boards such as the also known a kind of continuous production particieboard of people, fiberboard in addition, by this method, the compacting backing strap is made of a kind of original stock of in form forming for smear metal and/or fiber and a kind of moisture binding agent, its humidity is less than standard humidity, suppress just water steam preheating before introducing top clearance of backing strap in this case, make its humidity approximate consistent at least with standard humidity.Standard humidity refers to the humidity commonly used that depends on product, can be different with this humidity processing and according to the composition of original stock usually.This standard humidity is at least about 10 to 12 weight %.It is made up of the water of cell moisture and moisture binding agent.In this case, people wish to accomplish not produce any problem because of including steam in the warm of compacting backing strap, and can increase compacting output (seeing DE3914106A1) in addition when shortening forcing press length.
The method of also known a kind of continuous production composite wood boards such as particieboard, fiberboard etc., according to said method, the compacting backing strap of making in advance is after between the extruding steel band of introducing continuously the forcing press of processing, under the situation that adopts pressure, heating and cooling, make composite wood boards be in net shape and sclerosis.The forcing press location is divided into forcing press bringing-up section, forcing press heating cooling section and forcing press cooling section more in this case, wherein, and a plurality of both can the heating and/or also coolable section of design in forcing press heating cooling section.Particularly, the forcing press heating cooling section that one or more active regions are arranged adapts with the concrete reaction temperature of binding agent and/or type, packing and the thickness of compacting backing strap so that realize changeably or cut-in pressure machine bringing-up section or cut-in pressure machine cooling section.Two partial pressure machines have been realized in this case, that is a heated press and a cooling pressure machine, the cooling pressure machine that wherein is located at the heated press downstream has a cooling section, so that avoid overheated significantly and reduce steam pressure, and thereby prevents the drying that product is harmful.In the forcing press cooling section, will push steel band and be cooled to about 120 ℃ and be lower than 120 ℃ from about 220 ℃.The Mass Distribution that depends on sheeted product allows to connect changeably and can heat and coolable stripper plate, wherein cool off at the extruding steel band that rolls the bar cocycle and also cool off these and roll the composite wood boards that bar can make production higher final moisture content is arranged, need not to carry out temperature humidity afterwards and handle (seeing DE19858152A1).
At last, the method of the also known a kind of continuous production composite wood boards of people, according to said method, the heat that in the forward region in the forcing press location of continuous press, is transferred to a kind of heat-carrying agent take from the rear area of forcing press location heat-carrying agent and in the forcing press location beyond utilize.In this case, comprising the extruding steel band of continuous circulation, be used for pushing the roll-type bar of steel band and can heat and the double belt press of coolable stripper plate that people wish conserve energy (seeing WO99/46111).
Summary of the invention
The purpose of this invention is to provide and a kind ofly producing particieboard, fiberboard and the similar method of compacting and pressing and hardening cushions in the process of composite wood boards, according to said method, can the best and bigger product of output of the quality of production with lower process temperature.In addition, should create a kind of equipment of implementing the method, this equipment be characterised in that shorten improved under the situation of structure length speed of production and thereby improve plate output, meanwhile do not influence product quality.
For reaching this purpose, the present invention has advised a kind of being used in process compacting of producing particieboard, fiberboard and similar composite wood boards and the method for solidifying the compacting backing strap, wherein,
-compacting backing strap imports in the continuous press of the continuous operation that constitutes top clearance between the extruding steel band,
-compacting backing strap in top clearance by the standard of the predetermined extruding force curve of determining along top clearance and by the standard compression and the sclerosis of the predetermined temperature curve of determining along top clearance,
-sheeted product is water steam preheating before introducing top clearance just, makes its humidity consistent with the humidity of being scheduled to,
-compacting backing strap in the anterior thermal treatment zone of top clearance by the extruding steel band of segmented stripper plate heater, preheating with at stripper plate and the spontaneous process temperature that is heated to of roll-type bar that pushes the preheating that moves between the steel band,
-compacting backing strap at it by lowering the district through a steam pressure in the path of top clearance, and segmented reduce in the process of extruding force and/or segmented cooling stripper plate by process temperature predetermined reduce to remove predetermined amount of steam.
Also there is this possibility in addition within the scope of the invention, that is, in reducing the zone of extruding force, extracts steam, gas and the association material of discharging out from the top clearance both sides.The association material for example refers to the binding agent composition, as the volatile ingredient and the similar harmful substance of formaldehyde, hydrophobic wax.
By instruction of the present invention, the compacting backing strap that suppress at first carries out humidification one time with the Steam/air mixture of pure water steam or high concentration, and the feasible damping device that adds of not needing is as the flusher on backing strap surface.The humidity that can improve then and thereby the thermal conductivity that improved and the speed of production processing that therefore improved.There is this possibility here, promptly suppresses the thing pad and before introducing top clearance, apply saturated vapor, so that adjust according to sheeted product and thickness of slab and the required humidity of binding agent.Cause reducing cost with the saturated vapor processing, because the compacting backing strap needn't be dry especially.If adopt shock effect to handle, then steam is more promptly invaded the backing strap depths.In addition, the present invention is a starting point with following understanding, that is, for some process, moist composite wood boards is compared more suitable with relatively drier wood materials, and the wood materials of this drying must carry out humidity to be handled.The shaping of wood chip and/or fiber processing not only with temperature but also relevant with humidity.Along with the increase temperature of humidity just can form processing under the situation far below 100 ℃.In addition, by infeeding water vapour and saturated vapor especially, can make full use of under the situation of the heat of condensation before pressing process just to relevant compacting backing strap heat supply.This is favourable for the compacting backing strap that enters in the anterior thermal treatment zone of top clearance, carries out pressing process because so can reduce the stripper plate that heats by sectional in the anterior thermal treatment zone of length at one there.Owing to this reason, the preheating of no matter pushing steel band and still be the roll-type bar is also in backhaul and thereby carried out before entering top clearance.Be preheating to roll-type bar and extruding steel band that we can say extrusion temperature and aspect heat power engineering, be in neutral state with respect to the stripper plate of heating and the compacting backing strap that enters.In fact the heat that extracts in the cooling procedure that the forcing press outlet takes place is supplied with the extruding steel band and the roll-type bar of circulation again, so still be provided at required surface temperature in the forcing press import or the anterior thermal treatment zone fully.The thermal treatment zone is the same therewith, lowers the district thereby also can shorten length by instruction steam pressure of the present invention, not only can be by reducing extruding force but also can on purpose carrying out by the cooling stripper plate because remove steam there.Reduce steam pressure and not only reach, and realize by cooling procedure by decompression.The available heat-carrying agent identical with the stripper plate heating of the cooling of stripper plate here carries out, just supply with heat-carrying agent as long as only be useful on the stripper plate zone of cooling, its temperature is under the temperature of the heat-carrying agent that infeeds the stripper plate zone that is given for heating significantly.But stripper plate can not heat in the forcing press outlet area yet, or carries out the active cooling with special cooling medium.The decline of steam pressure allows to produce relatively moister composite wood boards in steam pressure lowers the district in cooling procedure.Reason has also avoided composite wood boards to cause cracking based on high steam pressure thus.In addition, take these cooling provisions to derive those and in the continuous press of continuous operation, be transported to dragging sliding hot (Schl eppw Zhuo me) the forcing press outlet from the forcing press import by extruding steel band, roll-type bar and compacting backing strap itself.All the time can realize on purpose reducing steam pressure and cooling steam hypotension district within the scope of the invention, so that the removal steam of compacting backing strap.Thus reason can be under the situation that shortens forcing press length with higher speed of production with especially improved the processing of quality ground, and with the composite wood boards that will produce be thin or thick haveing nothing to do.Can consider a large amount of radiations during decompression, therefore take steam or the gas and the association material of discharging away from top clearance.
The following describes by other features of the present invention.For example by the present invention's regulation, extruding steel band and roll-type bar are preheating to identical or different temperature in order to obtain special effect before they redirect to compressor inlet in the backhaul section.Especially when extruding steel band and roll-type bar by means of being pressed against heating plate on roll-type bar and/or the extruding steel band when directly contacting preheating, then the mode by the best succeeds in doing this point especially, wherein the roll-type bar rolls on this heating plate.In this present invention's recommendation on the one hand, the extruding steel band is pressed against on the roll-type bar by the direction of hold-down roller towards heating plate.But the extruding steel band also can be on the heatable bending roller or preheating in a heat tunnel that is passed through by it.For example, the heat that extracts from stripper plate in the forcing press outlet area can be applicable to heating and maintenance temperature in heat tunnel.In addition, can imagine by the induction the method preheating.By another kind of form of implementation, extruding steel band and roll-type bar via towards the operation of their arched heating plates, and are pressed against on this heating plate owing to this is arched before it redirect to the forcing press import.Rightly, in the anterior thermal treatment zone of top clearance, process temperature is adjusted into 220 ℃ to 240 ℃, and is reduced to 140 ℃ to 120 ℃ in the steam pressure attenuating district at rear portion internal procedure temperature.Thus, irrelevant with the reduction of extruding force, reached enough cooling to reduce steam pressure.By a kind of form of implementation of the present invention, in steam pressure lowers the district, reduce extruding force and can successively carry out with the cooling stripper plate.But also there is this possibility, in steam pressure lowers the district, reduces extruding force and cooling stripper plate intersection or superimposed carrying out.Thus, optimize on the one hand the decline of steam pressure, can produce composite wood boards on the other hand, although by exhaust steam loose heat energy and be accompanied by and reduce temperature and reduced humidity with enough humidity.Replenish by measure of the present invention all the time can be on a relatively shorter continuously operating press with high pass through speed and thereby high output process.Obviously improve the quality in addition.
Theme of the present invention also comprises a kind of continuously operating press that is used to implement needed technological measure, it comprises forcing press top, forcing press bottom and reaches the extruding steel band of the top clearance of circulation formation continuously in the forcing press bottom on forcing press top, wherein, the extruding steel band is guided on stripper plate under the situation that the roll-type bar connects as the centre in the top clearance district, stripper plate from the forcing press import extend to the forcing press outlet and the situation lower support that connects as the centre at the steam-cylinder piston device forcing press top and directly be bearing in the forcing press bottom.This continuously operating press or continous pressing machine be characterised in that, in the forcing press entrance region or just establish a preheating device that comprises steam generator before the forcing press entrance region; Stripper plate has many heating circuits that separate that are used for heating of segmented plate and plate cooling along the sheeted product traffic direction; And, forwardly crush zone constitutes the thermal treatment zone, constitute steam pressure at the rear portion crush zone and lower the district, these zones infeed the heating and cooling medium selectively by heating circuit and are variable by the steam-cylinder piston device that acts on the upper compressive plate by producing selectively and reducing extruding force.Can be provided with adjustment independent of each other loop at upper compressive plate and the heating circuit that in the stripper plate of bottom, separates, so that compensation possible temperature difference between upper compressive plate and bottom stripper plate for example uses the punching press of operation simultaneously to filter.Within the scope of the invention, selecting to supply with under the situation of heating and cooling medium, as mentioning in the above, available a kind of heat transport fluid work, this heat transport fluid is being considered under the situation of corresponding temperature difference on the one hand as heat medium work, on the other hand as cooling medium work.
Consider that stripper plate has this fact of a plurality of heating circuits, have this possibility, but the zone target of promptly different plates is supplied with heat medium and supplied with cooling medium on the other hand on the one hand exactly.The higher heat transport fluid of supplying temperature is used to heat stripper plate in the thermal treatment zone as heat medium, and the carrier fluid that supplying temperature is lower is used to cool off stripper plate as cooling medium, and the removal steam of suppressing backing strap in the steam depressor area.Reducing extruding force there also can be designed to variable according to the thickness of slab of specific requirement by means of the steam-cylinder piston device.Rightly, for the backhaul Duan Zaiqi of extruding steel band establishes heating plate before redirecting to the forcing press import by bending roller, heating plate can be pressed against on the extruding steel band between the extruding steel band and under the roll-type bar that is rolling on the heating plate respectively situation about connecting as the centre.Here, the extruding steel band is along direction compacted roller loading at the heating plate two ends of operation, so that reach between heating plate, roll-type bar and extruding steel band for exceptionally close contact of conducting heat.There is this possibility by another kind of form of implementation of the present invention, promptly pushing steel band and roll-type bar can by the chain of synchronous circulation or add on the heating plate that pressure zone is pressed against fixed-site, and/or heating plate can be pressed against on the circulating pressurized band that locate on fixed-site ground but synchronous.
The present invention also instructs, and continuous suction hood or a plurality of tandem hood and jetting device are in case of necessity established in the both sides of top clearance in steam pressure lowers the district, so that realize steam, gas and the association material that the eliminating of nothing to find fault with, be without rebuke ground is radiated.But also have such possibility, the both sides of top clearance are provided with the suction tube in variable action district in steam pressure lowers the district, and the active region can be by valve or guiding valve adjustment.This be it is also contemplated that suction hood and suction tube are set, in this case suction tube is connected on the suction hood.Suction hood can manually or automatically be adjusted into, and can take steam, gas and the association material of generation fully away.This adjustment can certainly succeed in doing by suction tube and adjustable valve thereof or guiding valve.
