Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, the structure of wide cut coater oven of the present invention is, two Fans 1 and two radiators 5 are provided with on the top of oven ncavity, two Fans 1 and two radiators 5 are separately positioned on the horizontal both sides of baking oven, two radiators 5 are communicated with deep fat pipe 7 by threeway 6, and deep fat pipe 7 is connected with the heating system in the external world; The air outlet of two blower fans 1 is communicated with the blast pipe 2 of side with the hot-blast outlet of radiator 5 simultaneously; The bottom of oven ncavity is provided with laterally zygomorphic blowing up bellows 3 and blowing down bellows 4, horizontal blanking between blowing up bellows 3 and blowing down bellows 4 is the route of walking about of material film, tuyere 10 subtend material film on blowing up bellows 3 and blowing down bellows 4, the blast pipe 2 of both sides is communicated with blowing down bellows 4 with blowing up bellows 3 simultaneously, is respectively arranged with air-flow plate 9 at blowing up bellows 3 and blowing down bellows 4 air inlet; The baking oven wall on blowing up bellows 3 and blowing down bellows 4 side is provided with exhaust duct 8.
The advantage of two radiators 5 is used to be avoid the difficulty of a processing large scale radiator and the temperature inequality of the long generation of radiator heat pipe.
Hot wind flow process in wide cut coater oven of the present invention is, oven interior both sides blower fan 1 is the oven interior gas heated through radiator 5, assign in blowing up bellows 3 and blowing down bellows 4 by blast pipe 2, utilize air-flow plate 9, regulate the air quantity entering blowing up bellows 3 and blowing down bellows 4, guarantee according to the material film different needs of dry plasticizing up and down, and adopt different intakes.The thermal current ejected from the tuyere 10 of blowing up bellows 3 and blowing down bellows 4 is ejected into the upper and lower surface of material film, carries out drying and foams.About 70% hot-fluid of baking oven bottom, due to the draft effect of blower fan 1, circulates again through radiator 5, remains 30% hot blast and discharges outside case through exhaust duct 8, and the secondary that can not only realize heat energy like this utilizes, and can control again the DOP concentration in baking oven.
As can be seen from hot wind flow above, the layout of the layout of blower fan, up and down inner bellows structure, air nozzle structure, radiator is that directly impact is ejected into the temperature of hot blast, the key of velocity uniformity on material film.
First, the present invention adopts both sides blower fan air inlet, and every crosswind machine 1 is directly communicated with a blast pipe 2, so just avoids employing blower fan to connect blowing up bellows 3 and blowing down bellows 4 through two three ventilation ducts again, namely improve the uniformity entering upper and lower bellows hot blast, again reduce system wind resistance.
Secondly, with reference to Fig. 4, Fig. 7, blowing up bellows 3 are consistent with blowing down bellows 4 structure, and bellows profile is set to symmetrical structure, all adopts three-decker, and every one deck has specific effect,
Ground floor is hot blast guiding region, is connected with air inlet, and both sides enter the hot blast of blowing up bellows 3 and blowing down bellows 4, through the effect of internal diversion plate 11, the hot blast making left and right enter bellows is split, and avoids hot blast mixing in opposite directions, reduces energy loss and the resistance of hot blast.The present invention is provided with multiple tracks deflector 11 according to fluid mechanics principle in inside, is obstructed entry zone by bellows air inlet according to the ratio cut partition of zones of different air outlet area.Radian according to baking oven width and internal diversion plate 11 is arranged, and blowing up bellows 3 and blowing down bellows 4 inside are divided into 8 air intake regions.The region that deflector 11 separates is with symmetrical with upper and lower center line about baking oven, namely deflector 11 is along blowing up bellows 3 or blowing down bellows 4 center line symmetry, such hot blast guaranteeing to enter from both sides can not mix in oven interior, reduce internal loss and windage, under same blower press, the cold air blast velocity of tuyere can significantly improve.Adopt the symmetrical deflector structure of large radian to combine the inlet-duct area determined, ensure that tuyere is identical with the flow velocity of left and right in front and back.The layout requirements tuyere 11 of the deflector 11 in this structure can not be arranged on centerline, with reference to Fig. 4.
The second layer is hot blast mixed zone, ground floor and air outlet (third layer) transitional region, the hot blast of coming in through ground floor mixes in this region, oven temperature and the uneven hot blast of wind speed is entered from ground floor, making the temperature of hot blast and wind speed become even further after mixing, is the key ensureing that air outlet temperature is identical with wind speed.
Third layer is wind outlet area and tuyere district.Tuyere adopts two kinds of structures: the first, mesh structure, has even, soft feature; The second, air knife structure, has injection great efforts, the obvious feature of impact effect.Adopt different air nozzle structures according to the position of coater oven, if adopt three joint many air drafts mouth baking ovens, put the structure shown in employing Fig. 5 at baking oven near former rankings of material film entrance, the opening of this tuyere 10 is towards the side of retreading; Other each rankings are put and are adopted the structure shown in Fig. 6, the opening vertical subtend material film direction of tuyere 10.Object is the coating that can prevent hot blast from dispelling, and spray hot wind can be prevented again to be leaked to baking oven outside, more easily form negative pressure in porch.The present invention adopts oven structure, substantially increases stock drying time, is conducive to improving stock rate of drying.
