Technical field
The utility model relates to overflow downdraw produces sheet glass apparatus field, particularly a kind of well heater for formed from plate glass and annealing.
Background technology
Overflow downdraw is a kind of technology that glass work is produced sheet glass, at United States Patent (USP) 3,338, has described overflow downdraw in 696 and 3,682,609.Common overflow down draw technique comprises melten glass is transported in the overflow groove, then overflows from the both sides of overflow brick, separately and along the overflow brick two sides to dirty, in the bottom of overflow brick, crosses to form the sheet glass with great surface quality.
Sheet glass is stretched to final desirable thickness by a series of heating regions, and this heating region is called shaping area.Sheet glass overflow melting enters shaping area, by regulating the heater power of moulding heating interval, provides the corresponding temperature distribution of sheet glass field, so that sheet glass thickness and warpage reach predetermined index.Moulding rear plate glass enters the stress annealing interval, mainly be to rely on the power regulation of annealing furnace well heater to formulate suitable rate of temperature fall, eliminate the unrelieved stress of sheet glass, therefore each well heater in shaping area and annealing furnace must guarantee that working stability is reliable, will guarantee that simultaneously well heater is convenient to change.
The structure that existing well heater adopts stainless steel casing to inlay refractory brick, because the residing envrionment temperature of well heater work is at 600 ℃ ~ 900 ℃, under such hot environment, stainless steel casing will be out of shape by expanded by heating, cause the mutual interference and collision of several well heaters, cause easily the well heater Damage by Short Circuit.Because the stainless steel casing dilatational strain is serious, change very difficult after damaging.
The utility model content
The purpose of this utility model is to provide a kind of well heater for formed from plate glass and annealing.
For achieving the above object, the utility model has adopted following technical scheme.
Comprise heating stone or metal plate for standing a stove on as a precaution against fire, heater strip and incubation chamber, described heater strip is arranged on the front end face of heating stone or metal plate for standing a stove on as a precaution against fire, and the aft end face of heating stone or metal plate for standing a stove on as a precaution against fire is arranged on the incubation chamber.
Be provided with web member on the described incubation chamber, web member links to each other with the side of heating stone or metal plate for standing a stove on as a precaution against fire.
Described web member is fixed clamping bar, one side being welded on the incubation chamber of fixed clamping bar, the other side links to each other with groove on being opened in heating stone or metal plate for standing a stove on as a precaution against fire side.
Described groove is opened on the top side and bottom side of heating stone or metal plate for standing a stove on as a precaution against fire.
Described incubation chamber adopts stainless material to make, and is provided with heat insulation foam in the incubation chamber.
Described heating stone or metal plate for standing a stove on as a precaution against fire adopts refractory materials to make.
Well heater for formed from plate glass and annealing described in the utility model is arranged at the incubation chamber outside with heater strip by the heating stone or metal plate for standing a stove on as a precaution against fire, reduced the thermal deformation that is subjected to of incubation chamber in the heating wire works, and the replacing of well heater is also more convenient.
