The energy that those skilled in the art become known for heating can be provided by the source of routine.For example, enough energy can provide by burning or other thermal source of electricity, fuel.Energy can directly change into heat at point of application, perhaps indirectly by heating liquid such as water or oil, heated air such as air or inert gas or heating steam such as air-flow or conventional heat-transfer fluid.
Air chamber of the present invention is being right after the material part to form the gap between the bottom periphery of air chamber and material.This gap is the uniform basically space length between the bottom of material surface and air chamber preferably.Clearance distance better is below the 3cm, is more preferably below the 1.5cm, preferably below the 0.75cm.This air chamber is operated under barometric gradient and is made steam suck in the air chamber.When steam sucked air chamber, the air chamber that is right after material reduced to minimum with the dilute strength of steam.Except the gap, the dilution of steam component also can be attached to mechanical component in the air chamber by use, reduces to minimum as the extension among Fig. 2-4 35,37.When extending beyond fabric and contacting with heating platen 24, the extension also provides the sealing of side.
According to the present invention, preferably select the generation speed of total mass flow rate with gaseous component in the matter of matching closely.This will help to prevent the dilution or the loss of steam component.Total volumetric flow in the air chamber preferably be at least the steam component volume flow 100%.In addition, the present invention can realize uniform flow rate basically in the inlet surface of passing air chamber.Can realize when having headroom on one deck porous media in air chamber.In described situation, the pressure of side falls to fall with the pressure by porous media and ignores in headroom.Those skilled in the art will know that the aperture that can regulate headroom and porous media is to regulate the flow velocity by the inlet surface of air chamber.
In another better embodiment, the configurable gap drying system that routine is arranged of air chamber of the present invention.The gap drying system uses direct solvent condenses and the heat conduction combination for main heat transfer, does not therefore need to apply compulsory convection current with evaporation with take away the solvent evaporant.The gap drier is made of hot plate that is separated by little gap and cold drawing.The uncoated side of the contiguous fabric of hot plate provides energy with evaporation coating solvent.The contiguous coated side of cold drawing provides the driving force of condensation and the conveying of solvent evaporant to pass the gap.Cold drawing with surface configuration is provided, and it has prevented that liquid from dripping back on the surface of coating.Along with the substrate feed of coating by the gap between the two boards, recovery dry and solvent is carried out simultaneously.The gap drying system is described in U.S. Patent No. 6,047 fully, in 151,4,980,697,5,813,133,5,694,701,6,134,808 and 5,581,905, with them all with reference to being incorporated into this.
Air chamber can be arranged on the some optional points of gap drying system.For example, air chamber can place opposing ends, gap drier inside or their combination of gap drier.Fig. 5 a shows the air chamber 40 on the trailing edge 44 that is positioned at gap drying system 42.
In the configuration of the gap of routine drying type, some gaseous component is carried by suck out the back from the fabric of motion.Gaseous component in the gap between fabric and top board may be vital, because its common available evaporated components is saturated.This component (solvent or other component) may be vital, at this moment because of the reason of considering from environment, health or secure context.When this gap enough hour, the volume of this extraction flow Q can be easy to from fabric speed V
Fabric, maximal clearance height h
uAnd film/fabric width W calculates:
Q=(1/2) (V
Fabric) (W) (h
u)
For example, for the fabric speed of 0.508 meter per second, width is 1.53m, and the gap is 0.0492cm, this means that flow is 0.00123m
3/ second.This be one less and be considered to than with the more manageable flow of other conventional drying means (the present invention of gas phase flow-rate ratio exceeds the several number magnitude).
Like this, air chamber of the present invention is suitable for carrying and collecting the material of less volume in the contiguous gas phase of fabric.Its basic embodiment is shown in Fig. 5 a.Gap drying system 42 comprises the fabric 46 between cold plate 48 and hot plate 50.Spacing is that the gap of H is formed between the upper surface and cold plate 48 of fabric 46.Cold plate 48 comprises that capillary surface 52 is to carry the material of condensation from condensing surface 54.Air chamber 40 is configured in fabric 46 and leaves the gap part is left gap drying system 42 with collection gaseous component.
Applying sealing to the trailing edge of air chamber can help mass flow to pass through this air chamber.Sealing plays the cleaning effect to be left from the trailing edge of air chamber to prevent gas, so just forces it to enter in the air chamber.Sealing can comprise and is forced to gas or mechanical seal.Fig. 5 a has described along the optional air that is forced to of the downward direction of arrow on the exterior portion 41 of air chamber and has flowed F.Be forced to gas barrier by any gaseous component of fabric 46 carrying of motion.This gas can be air, nitrogen, carbon dioxide or other inert gas system of cleaning.
Mechanical seal also can be used to force gaseous component to enter in the air chamber.Fig. 5 b shows in the outside 41 of air chamber 40 and uses flexible seal parts 56 to reduce the amount of carrying by the diluent gas of air chamber 40.Flexible seal 56 can be pulled on fabric 46 or be placed the little gap location of fabric 46.In this case, the gap is uneven, is approximately 0 at the exit H near sealing.
Mechanical seal also can comprise contractile sealing mechanism shown in Figure 6.Show among the figure,, dispose contractile sealing mechanism 76, also comprise cold plate 68 and hot plate 70 together with air chamber 60 and gap drying system 62 for guaranteeing normal continued operation.In this configuration, contractile sealing mechanism 76 can be arranged on the littler gap location than the surface that is mechanically sealed to fabric 66 of other form.This less clearance more effectively is used for removing the gaseous component in boundary layer and can not scratch or damage coating or material surface when capturing gaseous component from the fabric 66 of motion.Gap to fabric 66 surfaces can be 0.00508-0.0508cm or bigger.The gap is more little, and the efficient of gaseous component of removing the boundary layer is high more.The efficient of contractile sealing mechanism 76 is improved by the thickness that increases sealing, will be maintained in sealing surfaces corresponding with fabric on the seal point 78 simultaneously.Use dummy roll 80 shown in Figure 6, then contractile sealing mechanism 76 has the shape that be cut into circular arc corresponding with the radius of dummy roll 80.The thickness of collapsible sealing mechanism can be that 1.5cm is extremely greater than 3cm.Plate is thick more, and sealing area is big more, and is so just more effective.Actual thickness is determined as dummy roll radius and dummy roll cornerite according to following factor.Sealing can be shifted to the position of contraction by using actuator 82 or other mechanical device.The configuration of holding up prevented to the pollution of sealing mechanism 76 with to the destruction of fabric 66, and allows ultra high build coating to pass through, and perhaps allows splicing thing or other thickening thing to pass through.But the contraction automation of the known collapsible sealing mechanism 76 of those skilled in the art also can be to known thickening thing, as the splicing or ultra high build coating control, perhaps, even can be connected the contraction that never reckons with situation to allow to run into sensor (as pritch, laser detector etc.) (not shown) for the thickening thing.
Equipment utilization of the present invention be used for material is fixed on the gap of material supporting device to guarantee to suit that is right after the air chamber part.Conventional materials-processing system and device are applicable to the present invention.
This equipment comprises aforesaid air chamber, is placed on the material with the gap between the bottom periphery of regulation material surface and air chamber.This air chamber is made of conventional substances also can be designed to satisfy special use standard.This air chamber can be used as the environment that there is or can be placed on sealing in independent device, during for example baker surrounds.In addition, randomly place the extinguishing device of air chamber and heat(ing) coil can comprise conventional known devices and material.
The above-mentioned energy is used for providing enough energy with at least a evaporated components in the evaporated material to this material.Common known heating and heat transfer unit (HTU) is applicable to the present invention in this area.
The vapor stream that concentrates that is collected in the air chamber can further separate as absorption, absorption, film separation or condensation with the separator and the method for common described routine.Those skilled in the art can select concrete lock out operation and device based on vapor composition and required separative efficiency.
