Description
Involved in the present invention is: be used to suppress the spreading machine that material bed or identical neutralizing layer shape in the compacting building board production process according to the attribute definition of claim 1, and the method for operating of a kind of spreading machine according to Claim 8.
For a long time, the wood shavings particle carries out desirable humidity and the temperature adjustment is emphasis and the direction that this professional domain is made great efforts always to suppressing in the wood-based plate process industry.Particularly under the prerequisite of the binding agent that does not damage used wood shavings particle and adding, be heated to meticulously on the technological requirement temperature, or be heated to, many reported in literature mistakes have been arranged very close to the content under this temperature.For the compacting material bed that will pave is heated to essential temperature, except high frequency radiation, also adopt the mixture of hot-air, steam or a kind of air and steam before compacting.For this reason, always carried out preheating before classification or continued operation forcing press usually, simultaneously partly, this also is in order to activate employed adhesive.When heating with high frequency radiation, it is necessary reaching a kind of uniform moisture distribution, because hot ester phenomenon might occur, the phenomenon of local heat deficiency perhaps occurs, and this brings adverse influence all for the wood-based plate of producing.Fluid is ejected in the compacting material bed whether reach optimum degree during also total in addition bad estimation preheating.In the machining of special layering and be the mating formation during compacting material bed of multilayer, use strong fluid to impact pressurization and just there is no need, too closely knit because the high current body may cause the particle of mating formation to be subjected to displacement with the part.Like this, having done accurately mats formation calculate and carry out technological preparation after, also to drop into the very big cost compacting material bed that goes to mat formation.Particularly locate under the situation of mating formation, when for example OSB or OSL wood-based plate are made, should guarantee that the wood shavings particle has the degree of orientation of higher percentage at needs.To this, with the air-flow of hot-air or vapor mixing vapour mating formation of orientation being expected to adopt the impact pressurization is disadvantageous to production.Translocation for compensator fluid body stream allows fluid pass the bed of material when being provided with a precharge usually before leading pressurization, with this pressure the compression layer of having mated formation is exerted pressure.When using the very thin material manufacturing of mating formation to have special tectal wood-based plate, the granule particle on the top layer even penetrate in the intermediate layer.
German patent DE 44 34 876 C2 have proposed a kind of method and apparatus of continuous manufacturing multilayer wood-based plate, suppress a kind of compacting material bed with the mat formation compound of different layers of the different equipment of mating formation in this equipment.This then compacting pad pressurizes on the forcing press of a continued operation and solidifies.It is introduced that another characteristics of this method and apparatus are to adjust the raw materials used temperature of each layer of preparation in paving station, use high-temperature steam or saturated vapor to improve temperature.To this, should reduce the adjustment humidity that adds glue wood shavings material not regulating under the degree condition commonly used of preheating.In the document, do not introduce in detail relevant preheating mat formation the material method or the particular content of equipment.
A kind of equipment and method of making wood-based plate disclosed in German patent DE 103 14 623 B3, in this method, woody debris mated formation into single or multiple lift slab material bed, under the pressure and temperature effect, be pressed into a kind of wood-based plate then, will have a roller to heat in this equipment of mating formation at least.The problem of this method is except whether the roller that has a heating can transmit enough heats to the material of mating formation, at the paving station place material of mating formation to be carried out preheating and also make heating cost too high and uneconomical.
German patent DE 10 2,005 035 244 A1 have also proposed a kind of method and apparatus, in this method, for moisture and the temperature of adjusting particle, when particle is unloaded down from the feed bin of mating formation or during water vapour enters into the particle curtain from the spreading head that has nozzle, the temperature of uperize is 100 °-180 ℃, and what preferentially select for use is 105 °-130 ℃.To this, in the spreading machine between the spreading head at quantitative feed bin and spreading head and/or guide plate place, the steam pressing plate of steam jet is housed on the width of whole spreading head and correspondingly impacts pressurization with steam.
Adopting the technological principle and the application of nozzle to pass through practical proof basically in the spreading head zone, is can guarantee good product quality and can improve output thus.Particularly under the situation with the thin wood-based plate of small lot batch manufacture, can carry out the optimization adjusting to the humidity and the temperature curve of the use material of mating formation.Practice shows, is carrying out with condition of different temperatures under the situation of start-up function, blocked operation and continued operation, can have the polycondensation of crucial influence.For this reason, by moist steam being incorporated on the part of appliance of cold conditions, for example, be injected on the nozzle, on the guide plate and/or near around the nozzle, can produce certain humidity by the condensation of steam.After the short time, the moisture of humidity enters into compacting material bed with the form of water droplet, or drops on the compacting material bed, thereby causes forming on production board the condensation spot.In addition, the gathering of moisture also can cause bonding and caking phenomenon.Particularly when producing the thin type plate continuously, allowing anything but has the condensation spot on the surface of plate.In addition, the bonding and the caking phenomenon of the material of mating formation can damage integral device, also are very disadvantageous to the product of being produced.Usually use and solidify very fast glue or binding agent, so more can cause bonding or caking sclerosis, and perhaps when just come off, thereby production is brought adverse effect.When making thin plate, for example with the thick compacting material bed of forcing press compacting 20mm of a continuous operation, compression ratio is 10 times, and corresponding finished product is of a size of 2mm.If in this case, there is a kind of fixed blob of viscose in the material bed of mating formation, then the density at this position will be very big, and during pressing will damage steel plate (intermittent pressure machine) or steel band (continous pressing machine).In general, employed forcing press all is provided with safety guard.Certainly, the forcing press emergency shutdown in continued operation also can cause not wishing the production loss that takes place, will spend the plenty of time usually in this case manually to remove the material bed of mating formation of the forcing press porch of continued operation.Afterwards, have only at once and could put into production again after harmonizing through the operation of short time.
The objective of the invention is: the district of mating formation at wood-based plate sets up a covering device, can adjust humidity and/or temperature by mentioned such in front by means of steam with this device, and the phenomenon of can not mat formation material bonding and/or caking.In addition, also design a kind of method of operating of this device (steaming process adjusting device).
Solution according to claim 1 spreading machine is: at the steam pressing plate place that is used for heated contact surface and/or steam way and/or steam jet place, establish a cover heater temperature is heated on the temperature of used steam.
The advanced design and the useful structure of this device in the dependent claims of back, have been provided.
The method that is used to operate spreading machine is: by means of a kind of heater steam pressing plate and/or guide plate and/or contact-making surface are heated on the temperature of the steam that uses.
By this a kind of possibility, promptly before using the steam pressing plate, corresponding machinery or part of appliance separately is preheating to the temperature that surpasses existing use steam, can avoid safely boning and/or the generation of caking phenomenon, and can not damage equipment (for example continuous operation type forcing press) parts in the production process.
In addition, as long as after the steam pressing plate after the preheating of a process comes into operation, just can guarantee that the material of mating formation that falls on steam pressing plate next door carries out the admission pressurization with the steam pressure and the vapor (steam) temperature of the best.Under the situation that the steam pressing plate does not heat, will on the steam pressing plate of cold conditions, produce condensed water on the one hand, this operates ensuing discharge is bad control.On the other hand, incipient stage of steam pressing plate up to reaching corresponding to used vapor (steam) temperature, the steam lower than regulated value temperature is always arranged, just can not make mat formation material or particle admission pressurization reach optimization in the incipient stage like this.
A kind of heater has constituted particularly advantageous version, and this heater is made of a sleeve pipe, and with a shell steam pipe device that is constituted is surrounded.For this structure, can use the identical energy, steam generator (being boiler), both can produce the heating steam that heater is used, also can produce the steam of the material steam processing usefulness of mating formation.To this, helpful especially is the heating that at first is used for heater from the primary steam of boiler for producing, is then used in the material pressurization of mating formation of spreading machine steam pressing plate place and impacts.
Therefore, can use the device of simplification to be used for steam preparation and equipment operation basically, thereby reduce cost of equipment significantly.In addition, the energy balance from double-circuit system at first is used for heater with steam, also is an advantage with this steam as the steam supply of mating formation again and then.If consider to use hot oil as heat medium at heating plant in a similar fashion, then need from this loop, to extract the forcing press heat supply that hot oil is used for a batch (-type) or continuous operation type.According to the temperature range of forcing press, be divided into two parts before and after in forcing press, using hot oil.Can certainly consider to adopt pure electric heat supply, but this heating all is very expensive in device structure and operation, and on adjustment, also lags behind very much at heating plant.This way is more suitable in the situation that must carry out rule (continuity) steam preheating to mat formation material or particle stream.
The professional knows, in the manufacturing process of all particieboards, fiberboard and strand board (Schnitzelplatten), all will use chip, fiber or the similar ligno-cellulosic materials that contains are carried out steam-heated apparatus and method.In addition, also can handle the compound of mating formation that adds a part of plastics or similar material with device of the present invention or method.Particularly high density fiberboard (HDF), medium density fibre board (MDF) (MDF), low density fiberboard (LDF) and OSB produce very important.
Claim from behind and following description to schematic diagram can be recognized further useful measure and project organization of object of the present invention.
The expressed content of each schematic diagram is:
Fig. 1 is furnished with the steam pressing plate according to spreading machine side view of the present invention on the guide plate of spreading head zone;
Fig. 2 arranges enlarged drawing according to Fig. 1 in the multiple mode that the material of quantitatively mating formation between feed bin and the spreading head falls position steam pressing plate,
Fig. 3 expects bedside degree direction sectional drawing and steam pressing plate and steam jet figure transverse to suppressing according to Fig. 1,
The steam pressing plate partial enlarged drawing that Fig. 4 is corresponding with guide plate according to Fig. 1.
According to schematic diagram as seen, the spreading machine 1 that is used to make the orienting spreading layer is made of a quantitative feed bin 2 and the spreading head 3 that is located at below it.Usually according to the requirement of manufacturing wood-based plate,, material 6 widths along spreading head 3 of mating formation in the quantitative feed bin 2 are transmitted, and be transported in the spreading head by means of discharging belt conveyor 13 and discharging conveying roller 12.To this, the material 6 of mating formation that first is implemented in the example according to the present invention rushes at adjustable guiding valve 4, and this guiding valve 4 will be mated formation and be expected that 6 import on the distribution discharge rolls 5, on spreading head 3 material 6 of mating formation be carried out cloth then.Behind the further cloth of the roller of back, the material 6 of mating formation is directed on the directed roller 9 at last through guide plate 7.At this, but directed roller 9 according to necessity orientation also non-directional ground the material of mating formation is put on the moulding band 10, constitute compacting material bed 11 thus, perhaps under the situation of the spreading machine 1 of an arranged in series, compacting material bed 11 has only one deck.Spreading head for pressing fibre board use in producing does not use directed roller, or only uses the roller of mating formation.Compacting material bed 11 as far as possible promptly pressurizes on a forcing press (not marking at this) then.This can be equipped with according to forcing press is that layer-stepping or continuous operation formula are made wood-based plate.Relevant wood-based plate or plastic plate manufacturing technology personnel are very familiar from the considerable documents and materials of the state of the art, do not repeat them here.This equally also is applicable to the production and the preliminary treatment of the material of mating formation of most types, as wood shavings, fiber, wood chip or similar material.
In order to make the material 6 of mating formation keep constant temperature, be provided with steam pressing plate 8 at guide plate 7 places or its back, steam is injected in the material 6 of mating formation of next door process.To this, from angle of the present invention, it is inessential that the upper area that steam pressing plate 8 is located at guide plate 7 also is provided in a side of following zone, crucial is guide plate 7 will the material 6 of mating formation be distributed to carefully steam pressing plate 8 around and don't produce and pile up.To the professional person is conspicuous, and this relates to a pure definition, and steam pressing plate 8 can be used as the guide plate use from external structure.From the structural design aspect, this depends on the necessity of using guide plate.For fear of the fault of mating formation, the arrangement of taking guide plate 7 to be connected with the steam pressing plate usually can avoid particularly appearing at the bonding or the accumulation of rear side like this.In order to guarantee successfully to mat formation, how to arrange steam pressing plate 8 or protect with shell, then allow wise designer's decision.Implement also can to combine in the example at second of Fig. 2 with the structure of first example, promptly near distribute roll 5 or quantitative feed bin 2 below install steam pressing plate 8.Should illustrate this, also can carry out preheating the material 6 of mating formation in the weighing area or toward the position of spreading head 3 material conveying series connection.In this case, must not draw off the material 6 of mating formation by force from quantitative feed bin 2, can only be to unload the material 6 of mating formation with a jet pipe or other conveying device.In a scheme of preferentially selecting for use, pawnshop charging is unloaded from quantitative feed bin 2 and is dropped on the guiding valve 4 in a flash, carries out uperize by means of steam pressing plate 8.But also an injection apparatus might be set below guide plate 4, and/or carry out uperize to the material 6 of mating formation that falls and/or slide with 20 ° (as figure) to 160 ° (not having figure).To this, the width of injection be equivalent to the to mat formation whole width of material 6 also can spray from both sides, but must be parallel with the direction of transfer of moulding band 10, to avoid the mistake of mating formation.For spraying with water vapour, the temperature of the steam of preferentially selecting for use is 100 °-180 ℃.
Under the situation of using many spreading machines 1, appearance can be pressed into the compacting material bed 11 of the multilayer of multilayer wood-based plate.To this, on different spreading machines 1, use the different material 6 of mating formation usually.According to the intermediate layer or the used material of mating formation of cover layer of the multilayer compacting bed of material, also must correspondingly adjust the different parameters of spreading machine, mainly be in order on the whole thickness of wood-based plate, to keep the neat thickness profile of lines.
Fig. 4 has expressed the enlarged detail of a steam pressing plate 8 that has corresponding guide plate 7.The very important point of the present invention is that steam way 16 is wrapped up by a controlled heater 17 of independence.For example, this heater can adopt resistance heated or suitable fluid (as steam, oil or the similar medium) heating of flowing.
Importantly, heater 17 can not only the steam way 16 that has steam jet 15 be heated to use on the vapor (steam) temperature, and can also heat the contact-making surface 14 of whole steam pressing plate 8 in case of necessity.At this, contact-making surface 14 is defined as a steam pressing plate or affiliated parts and the contacted area of material (or its powder) of mating formation, and has and condensation thing followed shortcoming.According to the structure and the installation of the steam pressing plate 8 that has guide plate 7, guide plate 7 also can, perhaps also must heat.For expressed use vapours 22 or hot oil among the figure is the version that adds the heater 17 of hot fluid, can consider the scheme that adopts sleeve pipe or square casing to carry heating steam 22 or hot oil.To this, sleeve pipe will be arranged round steam way 16.In order to heat, in guide plate 7 zones, sleeve pipe also can not be provided with joint shown in the figure or branch road with following the prescribed order.But the simplest contact mode of heating is to adopt the guide plate that has suitable heat-conducting connecting 21.
Version according to steam pressing plate 8, steam jet 15 can adopt flat nozzle, and/or by a kind of many rows formula near mode arrange (above moulding band 10), thereby make steam 18 can with line style and/or fan-shaped form go into to mat formation the material 6 in.To this, the arrangement of steam jet 15 expects 6 with different angles facing to mating formation as far as possible, thereby improves the efficient of steam way 16.For this reason, in a kind of version of preferentially selecting for use, the steam way 16 that is connected with heater 17 is rotatable as requested, perhaps by means of the tumbler on the supporting frame 20 19, the whole system that is made of steam pressing plate 8 and/or guide plate 7 is rotated.Implement in the example at one, the steam jet 15 on the steam pressing plate 8 can be arranged to sink to mode facing to contact-making surface 14.This can install a flat steam 18 inlets according to the used material of mating formation in the zone of contact-making surface 14, extend in the mobile material 6 of mating formation.In a version of preferentially selecting for use, have such advantage in addition, promptly from two ends simultaneously to steam way 16 uperizes, thereby can on steam jet 15, keep the injection form of the best.In order reasonably to make full use of the energy of steam, meaningfully, after vapours 22 is used, can also be transported in the steam way 16 steam 18 in heater 17 as steam pressing plate 8 usefulness.
As previously mentioned, according to spreading head expressed among Fig. 1, be one and be used to process the wood shavings layer of compacting orienting spreading material bed or the spreading head of wood fragments lamella.Certainly, this spreading head also can be to be used to mat formation the spreading head of fiber or other geometry material when having corresponding construction.
