Abstract
The utility model relates to an adjustable cover plate at an inlet of an annealing furnace, which belongs to annealing furnace auxiliaries in a super-white rolled glass production line and is capable of realizing small temperature difference of glass when entering the annealing furnace. A rotary support is fixed to the front end of the annealing furnace, one end of each cover plate is hinged with the rotary support, the other end of each cover plate is fixed to a steel wire rope, the other end of each steel wire rope passes around a fixed pulley block fixed to the top of the front end of the annealing furnace and is then connected with a hoist fixed to the lateral side of the annealing furnace, the cover plates are transversely equal in widths along the inlet of the annealing furnace, the cover plates can be arranged in multiple groups in transverse widths along the inlet of the annealing furnace, and each group corresponds to the rotary support, the steel wire ropes, the fixed pulleys and the hoists. Another steel wire rope is added to the front end of each cover plate for safety purpose, while the other end of the steel wire rope is fixed to the annealing furnace, and the length of the steel wire rope is set according to the fact that the front ends of the cover plates do not contact with glass. The adjustable cover plate has the advantages that transverse temperature difference of the glass entering the annealing furnace can be adjusted, and the adjusting means is simple and convenient.
Description
Technical field
The utility model relates to a kind of very white rolled glass production line annealing furnace supplementary unit, owing to reduce glass at the heat radiation at transition roller platform place and the transverse temperature difference of improvement calendering annealing furnace ingress glass, regulates with the transverse temperature that reduces annealing furnace A district.
Technical background
The rolled glass annealing furnace is one of visual plant in the rolled glass production line, it mainly acts on is that glass ribbon about 650 ℃ is cooled to 70 ℃ continuously, annealing furnace is divided into heat preservation zone (comprising A district, B district, C district) and non-heat preservation zone two parts, and wherein heat preservation zone is directly connected to the ANNEALING OF GLASS quality.The A district is positioned at annealing furnace foremost, and and then the transition roller platform is the preannealing district, and the high temp glass band that the transition roller platform is transported is cooled to the ceiling temperature of glass annealing, and the transverse temperature difference of adjusting glass ribbon simultaneously is to the scope that requires.
Be delivered into the calendering annealing furnace through the roller bench roller road that crosses that opens wide behind the glass extruder-calender, because glass directly is open under the room temperature environment, glass sheet temperatures reduces fast, makes that into the annealing furnace glass temperature is on the low side in this process; Because the heat radiation inequality causes transverse temperature difference excessive (portion of generalized case bottom temperature is low excessively with respect to the middle part temperature), it is very big to make that subsequent anneal workshop section A district adjusts glass transverse temperature difference pressure, and might influence glass quality simultaneously.
The utility model content
The purpose of this utility model is exactly that width has a narrow range of temperature when realizing that glass advances annealing furnace, and annealing furnace inlet adjustable cover is set above the transition roller platform.
In order to realize above-mentioned functions, the following technical scheme of the utility model:
A kind of annealing furnace inlet adjustable cover, swinging mounting is fixed on the annealing furnace front end, and cover plate one end and swinging mounting are hinged, and the other end is fixed on the steel hawser; The described steel hawser the other end is walked around the fixed pulley group that is fixed on front top on the annealing furnace and is fixed on the lateral windlass of annealing furnace and is connected; Described cover plate is laterally wide along annealing furnace inlet, also cover plate can be arranged to many groups along annealing furnace inlet transverse width, every group of corresponding rotating stand, steel hawser, fixed pulley, windlass respectively; For the sake of security, the front end of every cover plate is established a steel hawser in addition, and this steel hawser the other end is fixed on the annealing furnace, and its length does not contact glass with cover forward end and exceeds.
The utility model adopts the such scheme structure, and its advantage is: can adjust glass and enter the annealing furnace transverse temperature difference, and regulating measure is simple and convenient.
