Abstract
The present invention relates to improvement of structure of homogeneous furnace capable of carrying out anti explosive treatment on toughened glass. The invention provides a homogeneous furnace for toughened glass which is energy-saving and highly production efficient. The homogeneous furnace comprises a furnace body, a furnace door and an air cooler being installed on both sides of the furnace body respectively. The structure of the furnace is characterized in that a temperature-insulating layer is installed on the periphery of the furnace body, thermal cycle ducts are installed at the two sides of the furnace body and at the temperature-insulating layer on the top, a heater and a circulating fan are installed at the bottom and the top of the thermal cycle duct respectively, and a cooling cycle duct is installed between the thermal cycle ducts on the top of the furnace body.
Description
Technical field:
The present invention relates to toughened glass is prevented that the homogeneous furnace structure that self-destruction is handled improves.
Background technology:
Equipment of the present invention is that toughened glass is prevented the specific equipment that self-destruction is handled; Glass behind the tempering still can be revealed under the condition of no external force effect.Reason is because nickelous sulfide is high temperature attitude (α-Nis) in the heating phase that tempering is handled.The quick colling stages high temperature attitude of handling at tempering (α-Nis) has little time (β-Nis) change to cold state.This crystal conversion exists in the more than ten years after install from the several minutes after handling always.((β-Nis) can cause volumetric expansion breaks the inner stress equilibrium of glass to α-Nis) change into, causes toughened glass self-explosion.Make the toughened glass after the processing no longer produce self-destruction.Toughened glass is placed in the machining process of heating, be incubated, lower the temperature in the homogeneous stove.The security and the safety of toughened glass have been improved greatly.
The toughened glass product applications is very extensive: building glass, various vehicle glasses, solar battery glass, BIPV glass or the like.
Up to the present, general general applications toughened glass does not carry out homogenization treatment.But along with the application of toughened glass, for example in the high-end field; Bullet train, solar cell, BIPV glass or the like.No matter from use properties, economy and security all respects all require toughened glass that enough securities and safety must be arranged.In recent years, lot of domestic and international device fabrication commercial city was used for the processing units of toughened glass homogenization treatment in development.
Because the homogenization treatment process of toughened glass requires very high to temperature homogeneity and the variation of intensification rate of temperature fall.Otherwise do not reach due effect.Therefore the toughened glass homogenizer that comes out now all exists energy consumption high, the problem that working (machining) efficiency is low.Reach the uniform purpose of temperature in the course of processing through slowly adding gentle cooling for a long time.
Summary of the invention:
The present invention is exactly to the problems referred to above, and toughened glass homogeneous stove a kind of not only energy-conservation but also that enhance productivity is provided.
For realizing above-mentioned purpose; The present invention adopts following technical scheme, the present invention includes body of heater, and the two ends of body of heater are respectively arranged with fire door, cold blast engine; Its structural feature is to be provided with thermal insulation layer in the body of heater periphery; Be provided with the thermal cycling air channel in the thermal insulation layer at body of heater both sides and top, the bottom in thermal cycling air channel, top are respectively arranged with well heater, recirculation blower, are provided with the refrigeration cycle air channel between the thermal cycling air channel, top of body of heater.
Beneficial effect of the present invention:
1, the present invention can reach good temperature homogeneity:
Because the thermal cycling air channel in stove is designed with guide plate on importing and exporting; Make the air flow line of recirculated air parallel with glass surface; The bar shaped outlet of guide plate is alignd with each sheet glass clearance space, makes the circulating current non-resistance evenly through each sheet glass at interval, guarantees that air velocity is identical.The temperature difference that reaches between each different surfaces of glass and same block of glass of fast and each different positions of thermal equilibrium speed is minimum.The design in thermal cycling air channel meets air flow structure, reaches best circulating effect.
2, in the insulation process segment, can reach good temperature control precision:
Owing to be divided into five sections at the body of heater length direction; Every section independent heating temperature controlling system and heat balance system realize that the each point temperature homogeneity can be controlled in the stove ± 1.5 ℃ with interior (and the same category of device temperature-controlled precision is at ± 3 ℃); Can effectively guarantee quality product, enhance productivity.
3, accomplish that in heating and holding stage thermosteresis is minimum:
Because recirculation blower of the present invention is installed in the thermal insulation layer, has eliminated the thermosteresis that recirculation blower produces outside thermal insulation layer.Reduce energy consumption and shortened time process-cycle.
4, shorten time process-cycle, enhance productivity:
Owing to adopted cold blast engine, reach the purpose of discharging different heats at different temperature-fall periods through changing the cold blast engine air flow rate, make the rate of temperature fall of high temperature section and low-temperature zone identical.Shortened the time that cools greatly.Present device time process-cycle when tonburden 5000Kg is 7-8 hour.
