As shown in Figure 5, drying oven 70 is as follows: the drying oven unit 10 to adjacency, links the front end surface 12a of a side and the rear end surface 12b of opposite side by bolt.Now, the opening 14b of the opening 14a of the front end surface 12a of a side and the rear end surface 12b of opposite side keeps air-tightness by not shown seal.The material of seal is the material of organic solvent-resistant, such as enumerating polytetrafluoroethylene (PTFE) etc.If the sealing of seal 18 is good, omits bolt link and also can.In addition, drying oven 70 is arranged on drying oven chamber is set, but also has vented drum blower fan 28 to be arranged on the outside situation that drying oven arranges chamber.Even if be arranged on indoorly, blower export is connected with passage with the exhaust outlet towards building outside, therefore, can not be discharged into drying oven chamber is set from the exhaust of vented drum blower fan 28.
Now, as shown in Figure 6, link seven drying oven unit 10 and formation drying oven 70.For convenience of explanation, each drying oven unit 10 is started from left side to be called successively drying oven unit U1, drying oven unit U2 ..., drying oven unit U7.Thin plate 60 is from being configured in roller 72 uncoilings of the left end of drying oven 70, and at the eve of moving into drying oven 70, by not shown coater coating sizing-agent in the above, via the opening 14a of drying oven unit U1, moves in drying oven 70.After this, thin plate 60 is through each drying oven unit U1-U7, organic solvent is from 62 evaporations of slurry coated face thus, the organic solvent of this evaporation is discharged to outside by vented drum blower fan 28, final thin plate 60 is taken out of from the opening 14b of drying oven unit U7, and is wound up into the roller 74 of the right-hand member that is arranged on drying oven 70.From 62 evaporations of slurry coated face, this is to produce due to the infrared ray irradiating from infrared heater 36 with from hot blast the hot wind action that machine 26 is supplied to organic solvent.
And, use in advance this drying oven 70 to carry out in the situation that be dried the numerical simulation of the thin plate 60 with slurry coated face 62, the evaporation curve obtaining has characteristic as shown in Figure 6.With regard to this evaporation curve, thin plate 60 has just been moved into drying oven unit U1 not fully rising of thin plate temperature afterwards, therefore the evaporation capacity of organic solvent is few, after this, evaporation capacity becomes very large from drying oven unit U2 to drying oven unit U4, nearly all organic solvent is evaporated due to after drying oven unit U5 time, so evaporation capacity tails off.In this evaporation curve, in surpassing a plurality of drying ovens unit U2-U4 of the evaporation capacity threshold value dotting, if do not make the wind direction of hot blast all to equidirectional alignment, may there is the phenomenon that solvent accumulates.; in drying oven unit U2-U4; while existing hot blast wind direction to have the situation different from other unit; in the different place of this hot blast wind direction, (for example hot blast collides part or part away from each other each other) produces the smooth part of Air Flow sometimes, and accumulates evaporated solvent at this place.But at this, make the hot blast wind direction of these drying oven unit form equidirectional, therefore, evaporated solvent part is accumulated in difficult generation.In common design, there is following policy: consider separately each unit, guarantee to dilute the required hot blast rate of solvent flashing within the scope of it.Take above-mentionedly in basic situation, preferably, in the large region of the evaporation capacity of solvent, make as mentioned above the mechanism working in coordination for exhaust of each unit, thereby further improve security.
In addition, be arranged in drying oven unit U1, the U7 at the two ends of drying oven 70, the wind direction of hot blast is direction from outside to inside.Therefore, from the opening 14a of drying oven unit U1 and the opening 14b of drying oven unit U7, be all difficult to blow out hot blast.Now, both wind directions are contrary, and therefore, must have a point in stove is to produce the opposed tie point of wind direction, but as mentioned above, this tie point preferably sets in the little position of solvent evaporation amount.But evaporation curve according to applied slurry and therefore difference, is necessary the kind according to this slurry, moves to suitable position by described tie point.In the present invention, can change respectively wind direction by each drying oven unit, therefore, this operation is feasible.
In addition, the thin plate 60 as having slurry coated face 62 is had no particular limits, for example, but also can use the thin plate being coated with for the electrode of lithium rechargeable battery.As this thin plate, can enumerate by positive active material (or negative electrode active material) and adhesive, conductive material and the blended together electrode material slurry of organic solvent the first-class and example made of the thin plate of coating the metal materials such as aluminium or copper.Or, also can use and be coated with the not firing ceramics sheeting of firing ceramics formed body.As this thin plate, can enumerate ceramic particle is blended in to the slurry in adhesive, water (or organic solvent), be coated on the first-class and example made of firing ceramics sheeting.
According to the drying oven unit 10 of the present embodiment as above, by switching wind direction transfer valve 30, can set for, hot blast is flowed from the first blow vent 21a to the second blow vent 22a along the slurry coated face 62 of thin plate 60, or on the contrary, hot blast is flowed from the second blow vent 22a to the first blow vent 21a along the slurry coated face 62 of thin plate 60.That is, by switching wind direction transfer valve 30, can freely change Air Flow.
In addition, owing to possessing infrared heater 36, therefore, in the situation that being only difficult to dry slurry coated face 62 with hot blast, by being combined with infrared heater 36, can be dried at short notice slurry coated face 62.Especially, infrared heater 36 is for irradiating the infrared ray of the following wavelength of 3.5 μ m, and makes heater table surface temperature maintain the low temperature that is less than organic molten burning-point, therefore, can effectively evaporate organic solvent, and the problem that does not also exist organic solvent to be lighted.
Further, hot blast produces machine 26 or vented drum blower fan 28 can regulate air quantity, therefore, not only can change the wind direction of hot blast, can also freely change air quantity.
Further, drying oven 70 is, the mode being connected along the throughput direction of thin plate 60 with each transfer passage links the drying oven of a plurality of drying ovens unit U1-U7, therefore, by switching the wind direction transfer valve 30 of each drying oven unit U1-U7, can freely change respectively Air Flow by each drying oven unit U1-U7.For example, can make mobile formation equidirectional or the rightabout of the hot blast of adjacent drying oven unit.In addition, forming in rightabout situation, can make the mobile collision of hot blast, maybe can make hot blast flow away from.Can be according to evaporation curve, the hot blast of adjusting each drying oven unit U1-U7 flows, the phenomenon of accumulating not produce solvent.
In addition, in drying oven 70, drying oven unit U1, the U7 that is configured in two ends take hot blast wind direction as from outside towards the mode of interior direction, set, therefore, from the transfer passage 14 of drying oven unit U1 and the transfer passage 14 of drying oven unit U7, be all difficult to blow out hot blast.Its result, can maintain the environment that the drying oven that is provided with drying oven 70 arranges chamber well.
In addition, the present invention is not limited to above-mentioned embodiment, certainly so long as belong to technical scope of the present invention, and just can be with various scheme implementations.
