Fig. 2 is that the utility model convection current air knife is installed to longitudinal sectional view on convection current wind path.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, the present embodiment air knife type forced convection type glass tempering process furnace, comprise body of heater 1 and be arranged on the process furnace silk in body of heater 1, convection current air knife 6, Transmission roller-way 3, be arranged on the high temperature circulation blower fan 4 of body of heater outside, described high temperature circulation blower fan 4 is communicated with by convection current wind path 5 with convection current air knife 6, described process furnace silk comprises the top stove silk 7 being arranged on upper of furnace body, be arranged on the lower furnace silk 8 of lower portion of furnace body, can realize, lower both direction is simultaneously to glass heats, described convection current air knife 6, Transmission roller 3 is all arranged between top stove silk 7 and lower furnace silk 8, conveniently product is transported in process furnace, lower radiant plate 8 is provided with between described lower furnace silk 7 and Transmission roller-way 6, by supporting the effect being installed in body of heater 1 and playing protection and homogeneous radiation lower furnace silk 9.
The present embodiment is by being obliquely installed convection current air knife, high temperature circulation wind is forced and blows to uniformly on glass surface, bottom radiation plate is set simultaneously, the function of radiation can be realized, this process furnace is made not only to have convective heating function, also there is the function of radiation, not only can to the heating of common sheet float glass, also can to the heating requiring higher high reverse--bias type LOW glass, expand the scope of application of traditional heating stove, save the operating time, improve working (machining) efficiency, have that structure is simple, easy to operate, the advantage of low cost of manufacture.
In the present embodiment, described lower radiant plate covers completely on lower furnace silk.On the one hand can prevent from glass from stove, heating breakage to drop on lower furnace silk 8, make operation safer, on the other hand, by lower radiant plate 9 even heat of lower furnace silk 8 is radiated on glass surface, improve the quality of products.
In the present embodiment, described top stove silk 7, lower furnace silk 8 adopt heat-stable material to make.The preferred nichrome wire of embodiment, longer service life, cost is lower.
In the present embodiment, described convection current wind path 5, convection current air knife 6 all adopt stainless material to make.The present embodiment preferably adopts 0Cr25Ni20, and this material has the advantage of heat-resisting, anti-oxidant height, non-deformability, convection current wind path 5, convection current air knife 6 can be avoided to form oxide film after the heating and drop on glass surface, affect glass quality.
