Movable check curtain for annealing kiln

Abstract

The invention relates to the technical field of annealing kilns, and especially relates to a movable check curtain for an annealing kiln. The movable check curtain is mounted at the top of the kiln body of the annealing kiln, and comprises a curtain plate assembly and a lifting assembly for driving the curtain plate assembly to go up and down, the curtain plate assembly is located below the top ofthe kiln body, the top of the kiln body is provided with a mounting through hole for the curtain plate assembly to go through up and down, the lower end of the lifting assembly goes through the mounting through hole and is connected with the curtain plate assembly, and a sealing assembly for sealing the mounting through hole is detachably mounted in the mounting through hole. When the movable check curtain needs to be inspected and maintained, the sealing assembly can be taken out from the mounting through hole at the top of the kiln body, the curtain plate assembly can be lifted by the lifting assembly, and the curtain plate assembly is lifted from the internal of the kiln body to the outside of the kiln body by the curtain plate assembly in order to pull the movable check curtain whollyfrom the internal of the kiln body, so the movable check curtain can be repaired or replaced timely and conveniently, the hidden danger of tilting or falling of the curtain plate assembly is eliminated, production accidents are prevented, and the movable check curtain has the advantages of saving of time and labor during dismounting and mounting, and high efficiency.

Description

technical field [0001] The invention relates to the technical field of an annealing kiln, in particular to a movable curtain for an annealing kiln. Background technique [0002] In the glass production line, the annealing kiln is a kiln for annealing and cooling the glass plate, which cools the advancing glass plate from the tin tank from 600°C to 70°C in a controlled manner, and at the same time eliminates or reduces the residual stress in the glass plate , so that the internal structure of the glass plate tends to be uniform, so that it has good mechanical properties. [0003] The annealing process in the heat preservation zone of the annealing kiln is indirect cooling by cold air radiation. It is divided into A zone, B zone and C zone. Among them, A zone is the front zone of the annealing kiln, and the temperature of the annealing zone is 600℃~540℃; B zone is the annealing zone, and the temperature of the annealing zone is 540℃~460℃; C zone It is the post-annealing zone...

AI Technical Summary

Problems solved by technology

The long-term use of the steel wire rope for hanging the curtain panel in this high-temperature environment will accelerate the deterioration of the aging material and even cause the risk of fracture, resulting in the breakage of the curtain steel wire rope and the accident of the curtain panel falling

Although the operating temperature of the curtain between Area A and Area B, and between Area B and Area C is relatively low, it also faces the above-mentioned risks under the condition of long-term use in a kiln period

Due to the limitation of the existing structure, the curtain cannot be pulled out of the kiln after the wire rope is broken, and it must be repaired or replaced in time

In severe cases, the curtain panel tilts in the kiln or falls on the rollers, causing production accidents and affecting normal production
