The forming technique of ultra-thin glass is high temperature rapid shaping.Using conventional anneal kiln, the molding annealing of ultra-thin glass cannot be satisfied
Demand.
Since ultra-thin photovoltaic glass thickness is only 1.5mm~2.0mm, the areas conventional anneal kiln A rollgang spacing is
250mm, the state of the ultra-thin glass plate drawn from calender at this time is extremely unstable, and the conveying roller of big spacing can lead to glass
Band is conveyed unsmooth or even can not be conveyed；It is affected by gravity, the glass between roller-way can sagging generation bending；Conventional anneal kiln, does not have
Heating temperature control means, glass tape plane stress transverse temperature difference it is excessive and caused by glass rupture.Therefore, traditional annealing kiln can not
It the behaviors such as conveyed, annealed to glass tape, cannot be satisfied the production of ultra-thin glass.
Utility model content
In order to solve the above-mentioned technical problem the utility model, provides a kind of ultra-thin photovoltaic glass high temperature rapid shaping annealing
Kiln.The present invention overcomes：1, the conveying 2 of glass tape after ultra-thin glass calendering, the flexural deformation 3 in glass tape transmission process,
It reduces plane stress and reduces glass rupture.So that ultra-thin photovoltaic glass is really shaped, annealing kiln is entered in the form of normal glass, it is complete
At the conveying and annealing of glass tape, to produce qualified photovoltaic ultra-thin glass.
To realize the utility model aim, following technical scheme is provided：A kind of ultra-thin photovoltaic glass is rapid-result soon with high temperature
Type annealing kiln, including kiln body, be sequentially arranged in A, B, C, D, RET, F warm area in kiln body, kiln body is passed through from feed end to discharge end

Interior nearly top is provided with that cooling duct, nearly bottom end is provided with heating device in kiln body, it is characterised in that the areas M, position are equipped with before the areas A
It is more than the conveying roller density of A, B, C, D, RET, F warm area in the density of the conveying roller in the areas M, the conveying roller being located in the areas M is independent
Adjustable speed motor is arranged to drive, temperature thermocouple is provided in the areas M, it is adjustable add to be located at the heating device in the areas M
Thermal, temperature thermocouple are electrically connected temperature control system, and heating device is adjusted in the connection of temperature control system signal.
Preferably, the ratio between the spacing distance between the spacing distance between the conveying roller in the areas A and the conveying roller in the areas M is：
25：18.
Preferably, adjustable heating device is at left and right sides of the areas M bottom, one group of electric heating tube, the areas M are installed respectively
It is uniformly distributed 6 groups of electric heating tubes altogether, every group of electric heating tube can independent temperature control.
Preferably, adjustable electric heater unit is set to the both sides of kiln body bottom end and is intervally arranged along its length.
Preferably, cooling duct is set as two extended along kiln body length direction.
A, B, C, D, RET, F warm area of the present invention is technical characteristic commonly used in the prior art, is expressed as：
The areas A：Annealing proparea, keeps glass tape temperature as uniform as possible, controls and reaches the temperature range before annealing.
The areas B：Important annealed zone controls glass tape cooling velocity, reduces permanent stress, improves annealing quality.
The areas C：Cooling velocity is improved under conditions of not generating excessive temporary stress in annealing back zone.
The areas D：Transition region carries out that direct convection current is forced to cool down by the hot wind of temperature controllable.
The areas RET：Circulating air cooling zone carries out circulating cooling by hot-air in kiln.
The areas F：Direct cooling zone carries out contact convection current cooling to glass tape using air at room temperature.
Advantageous effect of the present invention：Present invention is generally directed to thickness 1.5mm ~ 2.0mm ultra-thin photovoltaic glass, by its into
One of preannealing process is carried out before entering the areas A, by inherent stress elimination, glass bending is effectively prevent to deform and burst, structure letter
Single transformation and high volume applications convenient for existing annealing kiln greatly improves production efficiency.The areas M use concentrated type roller-way, can guarantee
Just molding high temp glass band has good flatness, will not cause plate face flexural deformation because roller spacing is excessive.
The areas M can separately adjustable speed ratio, ensure when producing the larger glass of thickness deviation, will not be because of stack speed and annealing
Transmission speed is not directly proportional, and causes glass tape sheet stacking surface or break.
The controllable type electric heater unit of the areas M bottom, can be while conveying glass tape, to glass tape into trip temperature tune
Section.
The areas M can effectively be controlled by the heating power of temperature thermocouple and temperature control system automatic controlled electric heater
Glass tape transverse temperature difference reduces glass rupture caused by due to plane stress changes in production.
