A kind of glass basin annealing furnace
Technical field
The present invention relates to a kind of glass basin annealing furnace.
Background technology
Glass basin needs through the tempering operation behind hot bending at present, and the process of tempering is that glass basin is heated to certain temperature, and the shape of this temperature lower-glass basin remains unchanged; But inherent molecule produces motion; Stress and structure are relaxed, and glass basin controlled chilling speed makes glass under artificial control, pass through transformation range then; At the uniform prestress of the inner generation of glass; The stress characteristics that this prestressed character and hot water shock testing machine basin produce is just in time opposite, and both cancel out each other, and therefore the temperature tolerance of glass basin and intensity increase greatly.The tempering apparatus of glass basin generally includes process furnace, air-cooled tempering device, and process furnace is made up of steelwork and thermal insulation fire-resistant material, and is provided with temperature element and temperature controlling system is controlled furnace temperature automatically, and air-cooled tempering device comprises blower and air grid.Existing glass basin annealing furnace will be sent into process furnace with the glass basin of tempering through feeder earlier; Behind the band heating certain hour, the glass basin that will heat through identical feeder is sent into air-cooled tempering device and is carried out air-cooledly, and feeder is carrying glass basin all the time in this process; Cause process furnace not feed again; Thereby make the unloaded heating of process furnace, waste a large amount of energy, increased production cost; And cause the inefficiency of glass basin annealing furnace because process furnace and air-cooled tempering device can not be worked simultaneously, be difficult to deal with extensive need of rapid production.
Application number is " 200910305399.3 ", and the application name is called the Chinese invention patent of " complete processing of continuous tempering furnace and curved tempered glass ", discloses a kind of continuous tempering furnace that is used to process curved tempered glass; It comprises process furnace, the cold air track of quenching, and the front and back end of process furnace is respectively the charging and discharging mouth, and process furnace is made up of the hot briquetting district that sets gradually, the balanced heat preservation zone of glass, the district that is rapidly heated; Process furnace and quenching wind trench bottom are provided with track and drive unit, and operation has some can connect process furnace and the travelling car between the cold air track quenched on the track, and travelling car is moved by drive device drives; Having of this invention is rational in infrastructure, production efficiency is high, easy to operate, energy utilization rate advantages of higher, but to the tempering of glass basin; Because its thickness is thicker, complex-shaped, its heating and air-cooled time are longer, and this just requires the travelling car stroke longer; Floor space can be big; Need relate to the big cost input of enterprise, and the workshop transforms, and the tempering of glass basin is paid attention to air-cooled to the hot bending zone; Though therefore the annealing furnace of this disclosure of the Invention can be realized continuous tempering production, its tempering effect does not reach the requirement of glass basin.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, production efficiency is high, the glass basin annealing furnace of save energy.
The present invention addresses the above problem the technical scheme that is adopted: this glass basin annealing furnace; It is characterized in that: comprise support, process furnace, air-cooled tempering device, system, feeder and dumping device; Air-cooled tempering device and feeder are separately positioned on the both sides of process furnace; Process furnace and dumping device are separately positioned on the both sides of air-cooled tempering device, and said process furnace comprises upper furnace body and lower furnace body, and upper furnace body is fixed on the support; Lower furnace body is arranged on the support through the body of heater lifting device; Be provided with in the said lower furnace body and place the carriage liftable supporter that the glass basin carriage is used, air-cooled tempering device comprise air grid, down air grid, blower, on blow pipeline, the pipeline of blowing down, blower connects goes up the pipeline of blowing, the pipeline of blowing down; Last air-supply pipeline, the pipeline of blowing connects air grid, following air grid respectively down; Feeder comprises skid bed, charging cylinder, and skid bed is slidingly arranged on the support and by the charging air cylinder driven, dumping device comprises discharging platform, unloading rack, discharging cylinder, platform cylinder; Unloading rack is slidingly arranged on the discharging platform and is promoted by the discharging cylinder, and discharging platform is slidingly arranged on the moving track on the support and by the platform air cylinder driven.
The principle of work of this glass basin annealing furnace: lower furnace body moves downward through lifting device, and the carriage that is placed with glass basin is sent into process furnace by feeder, and carriage liftable supporter rising jack-up carriage realizes that skid bed and carriage break away from; Skid bed returns, and lower furnace body moves upward, and upper furnace body and lower furnace body are closed, behind the heating certain hour; Lower furnace body descends, and the carriage liftable supporter drives carriage and rises, and discharging platform slides to process furnace, and the discharging cylinder promotes unloading rack and moves; When treating that unloading rack carries the carriage below of moving the bearing glass basin, the carriage liftable supporter drives carriage and descends, thereby realizes that unloading rack holds up carriage; The discharging cylinder retracts unloading rack, and makes glass basin be parked between air grid, the following air grid, carries out air-cooled operation; After being with air-cooled completion, platform cylinder pulling discharging platform lets glass basin along with the air-cooled tempering device of moving away of discharging platform; Glass basin is taken off from unloading rack, accomplish the tempering process, glass basin is transferred to air-cooled tempering device from process furnace when; The feeder glass basin that another is to be heated is sent into process furnace, thereby has realized process furnace and the non-stop run simultaneously of air-cooled tempering device, has not only practiced thrift the energy; Reduce cost, also made the production efficiency of machine units time be doubled, adapted to extensive need of rapid production.Above-described working process all can realize that control is accomplished automatically by system, artificial only need glass basin loaded go up skid bed, take off from unloading rack behind the tempering and get final product, thereby practiced thrift manpower greatly, and easily be automated, standardized management controls.
