Description
Technical field
The present invention relates to toughened glass producing apparatus technical field, especially relate to the energy-saving toughened glass electric furnace of a kind of high-low pressure.
Background technology
Toughened glass is called quenching toughened glass again.It is when ordinary plate glass is heated to softening temperature (620 ℃-640 ℃) near glass in the tempering electric furnace, internal stress is eliminated in deformation by self, then glass is shifted out the tempering electric furnace, with the bull nozzle cold high pressure air is blowed to the two sides of glass again, make it and be cooled to room temperature rapidly and equably, can make toughened glass.Toughened glass is in inner tension and the stressed condition of outside pressurized, in case local generation is damaged, stress relief can take place just, and glass is broken into countless little fragments, and these fragments do not have sharp corners, are difficult for hurting sb.'s feelings.Simultaneously, because toughened glass has mechanical property and thermostability preferably, so in construction work, the vehicles and other fields, be widely used.
Usually, when a slice sheet glass is put the tempering electric furnace into and is carried out tempering, obvious bending (matrix) can take place in glass between the heating period of tempering, for LOW-E glass (Low emissivity, be low radiation coated glass), this crooked meeting is more obvious, and this causes because its surperficial rate of heating is different.
LOW-E glass is in common tempering electric furnace, the lower surface of glass is heated by conduction (contacting with roller) and radiation (heating resistor of bottom), and upper surface is covered by low-emissivity coating, and this coating can reflect the thermal radiation of stove top firing resistance, thereby can not very fast being heated.Because the glass bottom is subjected to the thermal unbalance meeting to produce different expansions with the top, so will cause the distortion of glass.This phenomenon not only can produce spot, even can produce optical skew at the centre portions of glass.So common annealing furnace can not carry out the tempering processing of LOW-E glass.
Along with the extension of glass deep processed product, country is to the raising of building energy conservation requirement, and the tempering consumption of LOW-E glass is increasing, and the performance to existing annealing furnace has proposed new requirement like this.
At present, the annealing furnace that carries out LOW-E glass tempering mainly contains dual mode:
1, adopts high-temperature blower convection circulation system.Its advantage is: big to flow, heat-exchange capacity is strong, glass heats efficient height.Its shortcoming is: the cost height, furnace chamber to be washed away seriously, and the high-temperature blower life-span is short, and vibrations are big, easily produce oxidation, fall slag, distortion, the later maintenance amount is big, and tens kilowatts of high-temperature blowers are all the time in the commentaries on classics of not stopping transport, and the idle work energy consumption is big.These shortcomings are still failed fine solution.
2, dual chamber furnace annealing furnace.Dual chamber furnace is optimal LOW-E glass tempering furnace.Its advantage is: the blower fan convection system is worked (about 350 ℃-400 ℃) at low temperatures, and Working environment is greatly improved, and is safe and reliable, the production capacity height.Its shortcoming is: manufacturing cost is too high.
Summary of the invention
The purpose of this invention is to provide the energy-saving toughened glass electric furnace of a kind of high-low pressure that existing common radiation annealing furnace is transformed, it is low, simple in structure, easy for installation that it has a cost, long-lived characteristics.Further, it has energy-efficient, reliable and stable characteristics, and can work sheet silver, two silver-colored LOW-E glass.
