Abstract
The utility model provides an oven air outlet structure, including going out the aerofoil, have multirow air-out structure along its length direction interval arrangement on the play aerofoil, every exhaust structure includes a plurality of exhaust vents that run through the upper and lower surface of aerofoil, and the aperture of a plurality of exhaust vents of every exhaust structure is gradual change structure. The utility model discloses a gradual change of air outlet size is arranged, it is great to make central point put the wind gap, the marginal wind gap is little, when the pole piece is from the oven wind gap below process of this structure, the regional drying rate in pole piece center is fast, the drying rate at pole piece edge is slow, can weaken the adverse effect that the drying rate of pole piece edge itself brought very fast, restrain thick liquids and flow to the edge, improve the homogeneity of pole piece surface density, the thick liquids that have effectively solved because the volatilization velocity difference caused at dry in-process is by the phenomenon that the center flows to both sides.
Description
Technical field
It the utility model is related to a kind of air outlet structure, more particularly to a kind of baking oven air outlet structure.
Background technology
Dry process is needed to remove the solvent in slurry after electrodes of lithium-ion batteries coating, it will usually to use high warm air
To accelerate the volatilization of solvent.The air outlet of general high warm air is evenly distributed in the top of pole piece, pole piece with certain speed from
Lower section is by the way that but the volatilization of the edge solvent of pole piece is very fast, and the slurry of pole piece central area can be to edge during drying
Flowing, cause accumulation of the material at edge, cause the uneven of pole piece surface density, in turn result in electrochemical during charge and discharge cycles
Learn the uneven of reaction.In addition, the extrorse flowing accumulation of slurry can also aggravate webbing phenomenon, follow-up roll-in retractable volume is caused
During drum side, broken belt, not only influence follow-up cutting, the accurate to dimension of laser cutting process, can also cause substantial amounts of
Scrap.
Utility model content
Based on technical problem present in background technology, the utility model proposes a kind of baking oven air outlet structure.
The utility model proposes a kind of baking oven air outlet structure, including exhausting plate, on exhausting plate along its length between
Every being disposed with multiple rows of air exhausting structure, often arranging air exhausting structure includes multiple exhaust vents through exhausting plate upper and lower surface, and often discharges
The aperture of multiple exhaust vents of wind structure is grading structure.
Preferably, the aperture for often arranging multiple exhaust vents of air exhausting structure is wide to exhausting plate from exhausting plate width first end
The degree end of direction second is gradually reduced.
Preferably, the aperture for often arranging the exhaust vent in medium position in air exhausting structure is maximum.
Preferably, it is equal that the distance between two exhaust vents of arbitrary neighborhood in air exhausting structure are often arranged.
Preferably, the distance between two air exhausting structures of arbitrary neighborhood are equal.
The utility model proposes baking oven air outlet structure, arranged by the gradual change of air outlet size, make center wind
Mouth is larger, and edge air port is small, and when pole piece passes through below the baking oven air port of the structure, pole piece central area rate of drying is fast,
The slow drying speed at pole piece edge, the adverse effect that rate of drying of pole piece edge itself is comparatively fast brought can be slackened, suppress slurry
To edge flowing, the uniformity of pole piece surface density is improved, is efficiently solved during drying because evaporation rate difference is made
Into phenomenon from center to both sides that flowed from of slurry.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of baking oven air outlet structure structural representation.
Embodiment
As shown in figure 1, Fig. 1 be the utility model proposes a kind of baking oven air outlet structure structural representation.
Reference picture 1, the utility model proposes a kind of baking oven air outlet structure, including exhausting plate 1, grown on exhausting plate 1 along it
Degree direction arranged for interval has multiple rows of air exhausting structure, and often arranging air exhausting structure includes multiple exhaust vents 2 through the upper and lower surface of exhausting plate 1
And the aperture for often arranging multiple exhaust vents 2 of air exhausting structure is grading structure；Often arrange the aperture of multiple exhaust vents 2 of air exhausting structure certainly
The width first end of exhausting plate 1 is gradually reduced to the second end of width of exhausting plate 1, and is often arranged in air exhausting structure and be in middle part
The aperture of the exhaust vent 2 of position is maximum.
Arranged by the gradual change of the pore size of exhaust vent 2, make the aperture of center exhaust vent 2 larger, the hole of edge exhaust vent 2
Footpath is smaller, by the continuous pole piece after one section of coating with (baking oven temperature of being passed by below 12m/min speed baking oven air outlet structure
Degree is arranged to 110 DEG C), pole piece is parallel with exhausting plate 1, and the center line of pole piece is overlapped with the center line of exhausting plate 1, in pole piece
Heart district domain rate of drying is fast, the slow drying speed at pole piece edge, can slacken what rate of drying of pole piece edge itself was comparatively fast brought
Adverse effect, suppress slurry to edge flowing, improve the uniformity of pole piece surface density, efficiently solve during drying by
The phenomenon that the slurry caused by evaporation rate difference flows from center to both sides.
In the present embodiment, the distance between two air exhausting structures of arbitrary neighborhood are equal, often arrange any phase in air exhausting structure
The distance between adjacent two exhaust vents 2 are equal, to ensure that the ratio of pole piece dry wind suffered in the process of walking is identical.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
