Description
Technical field
The present invention relates to casting machine field, particularly a kind of casting machine adds wet film static air exhausting device.
Background technology
Casting machine has been widely used in cast film molding art.The tape casting technique of current application is non-aqueous tape-casting moulding process, namely traditional casting technique.Non-aqueous tape-casting traditional is at present shaping comparatively ripe, be widely used at ceramic field, the solvent that solvent system is conventional has: toluene, dimethylbenzene, butanols, ethanol, methyl alcohol, trichloro-ethylene etc., traditional flow casting molding can obtain high-quality ceramic substrate, but because used organic solvent has volatility, toxicity and the factor such as on the high side, people start to attempt use water and make solvent and replace organic solvent.
Aqueous tape casting forming have cheap, nontoxicity meet environment protection emission requirement, nonflammable, reduce production process and the explosion-proof Regulation Cost of equipment is low etc. that advantage causes pays close attention to and study, but also owing to there are some intrinsic unsurmountable problems: 1. water evaporation rate is low, rate of drying is slow, cannot realize high speed curtain coating suitability for industrialized production; 2. need the binding agent of more high-load to realize blank strength, this brings again the problem of sintering coke discharging; 3. hydrogen bond causes ceramic powders reunion to cause flocculation cannot form the superior slurry required for stable flow casting molding of levelability, causes being difficult to obtain the high curtain coating material strip of thickness and precision; 4. slurry is responsive to changes in process parameters, not easily the fine and close smooth ceramic membrane of molded surface, and curtain coating blank strip surface easily produces the open defects such as a large amount of pin hole, cracking, pit.5. base substrate is in conjunction with insufficient, dry cracking easy to foaming, and base substrate fragility is large, flexible distortion; 6. defect causes stress to concentrate, and causes sintering cracking.For the 2nd and the technical solution scheme of the 3rd, my company is at a kind of NFC Magnetic Substrate of the Chinese patent applied for aqueous casting slurry and preparation method thereof and a kind of NFC Magnetic Substrate (application number: mention 201410424887.7), and my company has developed the high casting machine of a kind of cast film thickness precision, therefore the biggest obstacle that aqueous tape casting occurs at present is the high speed curtain coating suitability for industrialized production application that cannot realize high-quality base substrate, micro-pore of surface pinholes that non-conforming causes mutually and base substrate inside cannot be solved, the high speed evaporation that cannot break through water realizes suitability for industrialized production application, high tensile blank strip cannot be realized to ensure that coiled material following process clicking technique is produced.
Due in curtain coating dry run, grope to find that in dry run, gas overflows from upper surface, middle lower floor constantly upwards spreads according to psychrometric difference, and what needs did is the liquid movement speed balancing upper surface gas overflowing speed and middle lower floor, ensures gas overflowing passage as much as possible simultaneously.In preliminary process, in slurry, solvent strength is very large in addition, and utilize the concentration difference in itself and environment just can reach higher evaporation rate, the later stage is contrary.Thus low early and high after gradient drying system is adopted.And higher temperature makes surface and inner solvent volatilize fast, cause upper surface skinning and gas overflowing passage is closed, and the gas of the volatilization of inside does not have overflow channel, cause cracking and thickness instability, meanwhile, because the effect of washing on surface in dry run can have influence on slurry to the varied in thickness of blank strip and fluctuation, Chinese utility model patent, name is called the casting machine (application number: 200920055522.6) with microwave heating drying device, this utility model patent adopts multiple microwave heating box side by side, the temperature of each heating cabinet is controlled by temperature control system, but germ band is in dry run, the gas evaporated, do not discharged curtain coating drying tunnel timely, thus the temperature in casting machine drying tunnel is reduced gradually, thus it is uneven to make germ band be heated, affect product quality, and adopt multiple heating cabinet, add equipment cost and power consumption cost, microwave heating box very easily damages, add the cost of overhaul undoubtedly, waste the working time.
Therefore for the feature of water system formula dry run, the aerodynamics layout of baking zone inside and heterogeneity phantom and atmosphere backflow concentration ratio need be readjusted, design and produce a set of more reasonably curtain coating drying tunnel additional cushion current stabilization adjustment window, improve the dry bottleneck of traditional casting machine, make shorter casting machine device possess more efficient drying efficiency, thus realize the high speed curtain coating of water system formula on steel band casting machine.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, a kind of side of exhaust convenience is provided, the casting machine of safety and efficiently adds wet film static air exhausting device.
Object of the present invention is achieved through the following technical solutions: a kind of casting machine adds wet film static air exhausting device, it comprises casting machine, casting machine is provided with casting machine drying tunnel, the high order end of described casting machine drying tunnel is the first warm area drying tunnel, in the first described warm area drying tunnel, detachable division board is vertically installed, the first described warm area drying tunnel top is provided with the first warm area mesh plate, the first described warm area mesh plate offers multiple equally distributed ventilation mesh, the first described warm area mesh plate is provided with an additional casing, described additional casing top is provided with suction opeing, before and after additional casing, two sides are respectively arranged with a lower turning type glass self-priming window and two adjustable rotary air doors, described adjustable rotary air door is positioned at the both sides of lower turning type glass self-priming window.
Described adjustable rotary air door comprises fixing shielding plate and movable shielding plate, and described fixing shielding plate, movable shielding plate are by the fan-shaped composition of two lobes, and described movable shielding plate is arranged on fixing shielding plate by fixed screw.
