Description
Technical field
The utility model relates to a kind of equipment in glass chemistry toughening process, is specifically related to a kind of glass ring and learns tempering preheating oven.
Background technology
Chemical tempering is glass to be placed in to the alkali salt of melting, make the larger ion-exchange of radius in ion that in surface layer of glass, radius is less and fused salt, finally on two surfaces of glass, form compressive stress layer, inside at glass forms tension stress layer, reaches the object that improves glass machinery intensity and resisting temperature impact property.The strength of glass that processes by chemical tempering is high, Heat stability is good, and surface is indeformable, can do suitable cutting process, without self-destruction phenomenon.
Chemical toughening furnace generally comprises Reaktionsofen, preheating oven and cool furnace and bracing frame.Currently used preheating oven is the mode of line exhausting, and the area that the interior wind body of stove that is revolves nest is larger, and descent of temperature process is inhomogeneous, not only extended temperature fall time, also may cause glass in quenching or damaged shock heating in the situation that, increased the defective worry of product, cause the waste of raw material.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of glass chemistry toughening preheating oven, adopts face formula exhausting, reduces the area of wind body whirlpool in stove, make furnace temperature more even in decline process, improve the utilization ratio of conforming product rate and raw material.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
A glass chemistry toughening preheating oven, comprises body of heater, wind circulation device and the heating unit that is positioned at body of heater, and described body of heater comprises shell, inner bag, drop-bottom and fire door, between shell and inner bag, is provided with chuck, and described heating unit is arranged in chuck; Described drop-bottom and shell are slidably connected, and drop-bottom is controlled furnace bottom in shell basal sliding and opened and close; Described wind circulation device at least comprises four recirculation blowers, and recirculation blower is distributed on top board with body of heater top board centrosymmetry, is also provided with the venting hole and the blast inlet that communicate with inner bag on the top board of described body of heater; On described fire door, be provided for the programming Control panel of control heater and recirculation blower switch.
The utility model can also be realized by following scheme:
As a kind of preferred scheme of the present utility model, described furnace body outer wall is provided with thermofin.Thermofin is wrapped in the outer wall of body of heater, prevents from carrying out thermal exchange in stove and between external environment, further improves the utilization ratio of heat, reduces energy consumption.
As a kind of preferred scheme of the present utility model, described heating unit is U-shaped heating tube or straight shape heating tube or heating jacket.
As a kind of preferred scheme of the present utility model, the top of described fire door and bottom are all provided with supreme two rollers, on the body of heater of installation fire door, bottom and the top of corresponding fire door are respectively equipped with the slide rail matching with described roller, and fire door slides on slide rail by roller to realize and opens and close.The fire door of this sliding type facilitates material be sent in stove or take out in stove, has saved manpower.
Compared to existing technology, the beneficial effects of the utility model are: the utility model has changed the flow direction of wind in stove, from line exhausting, becomes face exhausting, thereby reduce the area that the interior wind body of stove revolves nest, make furnace temperature more even in decline process, improved conforming product rate, and reduced the production time.The utility model further improves the utilization ratio of heat by thermofin is set, reduce energy consumption; And by sliding type fire door handled easily is set, saved manpower.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is recirculation blower distribution schematic diagram described in the utility model.
Embodiment
As shown in Figure 1 and Figure 2, glass chemistry toughening preheating oven described in the utility model, comprise body of heater, wind circulation device and the heating unit that is positioned at body of heater, described body of heater comprises shell 1, inner bag 4, drop-bottom 3 and fire door (not shown), between shell 1 and inner bag 4, be provided with chuck 5, described heating unit 2 is arranged on chuck interior 5; Described drop-bottom 3 is slidably connected with shell 1, and drop-bottom 3 is controlled furnace bottom in shell basal sliding and opened and close; Described wind circulation device at least comprises four recirculation blowers 6, and recirculation blower 6 is distributed on top board with the top board centrosymmetry of body of heater, is also provided with the venting hole (not shown) and the blast inlet (not shown) that communicate with inner bag on described body of heater top board; On described fire door, be provided for controlling the programming Control panel of heating unit 2 and recirculation blower 6 switches.In the utility model, blower fan Main Function is after glass tempering reaction, evenly accelerate cooling, because it is mainly flowing of cooling furnace air, therefore at least four blower fans rationally arrange and action effect quite obvious, avoid on the one hand quenching in direct exposure air to cause glass to damage, improve on the other hand the working efficiency of two blower fans of tradition, evenly cooling, improve yield.
The utility model can also be realized by following scheme:
