Abstract
A kind of heating device for the molding Muffle furnace of glass provided by the utility model, including heating rod, insulation sleeve, soaking body casing and insulation construction, wherein, soaking body casing is sleeved on heating rod, insulation is placed between heating rod and soaking body casing, and insulation construction is sleeved on soaking body casing；Even if the corresponding region of the device insulation sleeve is damaged, also it can guarantee the air-tightness of whole heater assembly installation region, reduce the gas flowing of corresponding region, extend the service life of heating rod, the temperature profile effect on overflow launder periphery can be reduced to lesser extent, ensure the stable operation of overflow quality and production.
Description
Technical field
The utility model belongs to glass production field, and in particular to a kind of heating device for Muffle furnace.
Background technology
As the equipment of the various FPD functions such as laptop, smart mobile phone largely uses, for manufacturing tablet
The market demand of the planar substrates glass of display is significantly increased.Simultaneously because the use of large scale flat-panel monitor, for flat
The parameters such as size, flatness and the internal stress of face base plate glass propose increasingly higher demands.Substantially based on such demand
Rise, overflow downdraw occupies very important effect in the production of planar substrates glass.
Overflow downdraw in process of production, as depicted in figs. 1 and 2, depends critically upon the size to overflow launder and production
Space temperature field accurately controls in the process, but during the use of equipment, the service life of section heaters is difficult to reach
To the life-cycle operating mode of integral device, the temperature field generated in production process is in state very rambunctious, ultimately causes product
The serious of manufacturing cost increases or cannot be satisfied design requirement.
As shown in figure 3, existing silicon carbide spiral heater 1 (section is circle), the device 2 to be insulated by one is installed
In a soaking body casing 3, soaking body casing 3 is then fixed on insulation construction 4, concrete structure such as Fig. 1.Due to material
Characteristic, in dotted line marker location, after a period of time, 3 ablation of soaking body casing damage, silicon carbide can be caused to heat thereafter
The service life of stick drastically declines, but can not replace soaking body casing, simultaneously because soaking body casing ablation cause it is partially sealed go out
Existing problem so that local temperature field controlling is deteriorated.And then influence whole plate quality.
Invention content
The purpose of this utility model is to provide a kind of heating devices for Muffle furnace, solve existing soaking body set
Pipe ablation causes partially sealed go wrong so that local temperature field controlling is deteriorated, and then influences the defect of whole plate quality.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of heating device for the molding Muffle furnace of glass provided by the utility model, including heating rod, insulation sleeve,
Soaking body casing and insulation construction, wherein soaking body casing is sleeved on heating rod, and insulation is placed on heating rod and soaking body set
Between pipe, insulation construction is sleeved on soaking body casing.
Preferably, insulation sleeve is ladder flange-type structure, and the small end of insulation sleeve is placed between soaking body casing and heating rod；
It is close to the upper surface of insulation construction the big end lower surface of insulation sleeve.
Preferably, the small end end of insulation sleeve is placed in the lower section of insulation construction lower face.
Preferably, the distance between insulation sleeve small end end face and insulation construction lower face are 5-100mm.
Preferably, one end of soaking body casing is open end, and the end of the open end is placed in insulation construction lower face
Top.
Preferably, the distance between the end at soaking body ferrule openings end and insulation construction lower face are less than or equal to 80mm.
Compared with prior art, the utility model has the beneficial effects that：
A kind of heating device for the molding Muffle furnace of glass provided by the utility model, including heating rod, insulation sleeve,
Soaking body casing and insulation construction, wherein soaking body casing is sleeved on heating rod, and insulation is placed on heating rod and soaking body set
Between pipe, insulation construction is sleeved on soaking body casing；Even if the corresponding region of the device insulation sleeve can guarantee if being damaged
The air-tightness of whole heater assembly installation region reduces the gas flowing of corresponding region, extends the service life of heating rod,
The temperature profile effect on overflow launder periphery can be reduced to lesser extent, ensure that overflow quality and stablizing for production are transported

Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is further described.
As described in Figure 4, a kind of heating device for the molding Muffle furnace of glass provided by the utility model, including heating
Stick 1, insulation sleeve 2, soaking body casing 3 and insulation construction 4, wherein soaking body casing 3 is sleeved on heating rod 1, and insulation sleeve 2 is set
Between heating rod 1 and soaking body casing 3, insulation construction 4 is sleeved on soaking body casing 3.
Specifically：Insulation sleeve 2 is ladder flange-type structure, and the small end of insulation sleeve 2 is placed in soaking body casing 3 and heating rod 1
Between；It is close to the upper surface of insulation construction 4 the big end lower surface of insulation sleeve 2.
Meanwhile the small end end of insulation sleeve 2 is placed in the lower section of 4 lower face of insulation construction, it is preferable that 2 small end end of insulation sleeve
The distance between face and 4 lower face of insulation construction are 5-100mm.
One end of soaking body casing 3 seals, and the other end is equipped with opening；The open end end is placed in 4 lower end of insulation construction
The top in face.
The distance between end and 4 lower face of insulation construction of 3 open end of soaking body casing are less than or equal to 80mm.
The utility model design heating device, even if the corresponding region of insulation sleeve 2 can guarantee if being damaged it is whole
The air-tightness of heater assembly installation region reduces the gas flowing of corresponding region, extends the service life of heating rod, can incite somebody to action
The temperature profile effect on overflow launder periphery can be reduced to lesser extent, ensure the stable operation of overflow quality and production.
