Abstract
The utility model discloses a double-furnace equipment for tempering glass which consists of a low temperature warm-up furnace and a level steel furnace. The low temperature warm-up furnace and the level steel furnace are all consists of steel structure furnace bodies, level carrying roller paths, heating devices, temperature controlling devices, furnace door mechanisms and self-controlling devices. The low temperature warm-up furnace is arranged on the front end of the level steel furnace, the level carrying roller path of the low temperature warm-up furnace has the same elevation and the carrying speed with the level carrying roller path of the level steel furnace. The heating device of the low temperature war-up furnace consists of a plurality of hot wind circulating blowers which are arranged in the inner wall of the furnace body. The utility model has reasonable structure and is hard to be detonated when the glass is steeled; and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of heating installation, especially relates to a kind of process furnace that is used for glass tempering technology.
Background technology
The tempering of glass is exactly that glass heats is arrived near softening temperature, carries out quenching then, makes glass produce a kind of internal stress of even and regular distribution, thereby improves glass intensity, stability and security.The toughened glass production line is formed by going into sheet roller-way, annealing furnace, cooling air grid and slice roller-way usually, and horizontal annealing furnace is the most general a kind of glass tempering equipment that uses both at home and abroad at present.Horizontal annealing furnace is made up of steel construction body of heater, horizontal transmission roller-way, electrically heated temperature control unit, fire door mechanism and self-con-tained unit.Establish thermal insulation layer in the body of heater of the horizontal annealing furnace that uses at present, single furnace structure adopts the electrically heated form, and glass is carried out radiation heating, and furnace temperature is adjusted according to glass size, generally in 650-730 ℃ of scope.Glass enters in the annealing furnace from room temperature, stand violent temperature variation, and especially heavy sheet glass is very easy to cause burst, and causes serious industrial accident, thereby has greatly reduced the output of annealing furnace.
Summary of the invention
The utility model provides a kind of twin-furnace glass toughening device, and it is rational in infrastructure, is difficult for bursting the production efficiency height during glass tempering.
A kind of twin-furnace glass toughening device, form by high temperature preheating furnace and horizontal annealing furnace, high temperature preheating furnace and horizontal annealing furnace are formed by steel construction body of heater, horizontal transmission roller-way, heating unit, temperature control unit, fire door mechanism and self-con-tained unit, described high temperature preheating furnace is arranged on the front end of horizontal annealing furnace, the absolute altitude of the horizontal transmission roller-way of high temperature preheating furnace and the horizontal transmission roller-way of horizontal annealing furnace is consistent, transfer rate is identical, and temperature is controlled at 250-350 ℃ in the stove of high temperature preheating furnace.
The heating unit of described high temperature preheating furnace is made up of some hot air circulation blowers that are installed in inboard wall of furnace body.
The utility model is by the high temperature preheating furnace that adopts the forced convection heating and adopt horizontal annealing furnace two portions of radiation heating to form, and every part is established independent heating system, temperature control system, transmission system and robot control system(RCS).Glass is introduced into about high temperature preheating furnace internal heating to 300 ℃, make glass enter the temperature difference that annealing furnace stands later on and reduce, and has greatly reduced glass and burst phenomenon in annealing furnace, improves throughput.
The utility model can be transformed the previous level annealing furnace, can not have any impact to original production line, can greatly reduce unit surface glass energy consumption, improves income.
The utility model adopts independently modular design structure, and is rational in infrastructure, easy to operate, less investment, income height.
