Description

Movable check curtain of annealing kiln

Technical Field

The utility model relates to an annealing kiln technical field especially relates to an annealing kiln activity check apron.

Background

In a glass production line, an annealing kiln is a kiln for annealing and cooling glass plates, and the annealing kiln enables the glass plates which advance and come out of a tin bath to be controllably cooled to 70 ℃ from 600 ℃, and simultaneously eliminates or reduces residual stress in the glass plates, so that the internal structures of the glass plates tend to be uniform, and the glass plates have good mechanical properties.

The annealing process of the heat preservation area of the annealing kiln is the indirect cooling of cold air radiation. The annealing furnace is divided into an area A, an area B and an area C, wherein the area A is the front area of the annealing furnace, and the temperature of the annealing interval is 600-540 ℃; the B area is an annealing area, and the temperature of the annealing area is 540-460 ℃; the C area is an annealed area, and the temperature of the annealing area is 460-360 ℃. Each zone has a specific temperature interval and a cooling and heating process. The zones are separated from each other by the retaining curtains and the baffle structures so as to protect the annealing atmosphere of each zone from mutual interference and influence, and the glass plate can be fully annealed according to the annealing curve when running in each zone. The block curtain is generally arranged at the front end or the rear end of each zone, namely the block curtains are arranged in front of and behind each zone of the zones A, B and C. The lower curtain plates extend into the kiln and are arranged above the glass, and the upper adjusting handle and the hand-operated winch are arranged outside the kiln. When the kiln is baked, the curtain plates are lowered below the roller surface, and a closed space is formed in each area, so that the quantitative temperature rise and fall are facilitated; the shutter slats were raised approximately 50mm above the roller surface during normal production, with this 50mm height space being available for glass sheet passage.

Because the temperature in the kiln in the heat preservation area is higher, particularly the temperature at the front end curtain plate of the area A reaches more than 600 ℃, and open fire from the tail end of the tin bath is blown to the position. The steel wire rope for hoisting the curtain plate is used in the high-temperature environment for a long time, the degeneration of the aged material is accelerated, and even the risk of fracture is caused, so that the steel wire rope for the curtain is fractured and the curtain plate falls. Although the use temperature of the curtain between the zones a and B and between the zones B and C is relatively low, the curtain is exposed to the above-mentioned risks in a long-term use condition of the kiln. Limited by the existing structure, the check curtain can not be pulled out of the kiln after the steel wire rope is broken, and the check curtain can be overhauled or replaced in time. In severe cases, the curtain plates are inclined in the kiln or are placed on the rollers, so that production accidents are caused, and normal production is influenced.
