Rapid blocking device for mounting window of substrate glass forming furnace equipment

Abstract

The invention discloses a rapid blocking device for a mounting window of substrate glass forming furnace equipment. The rapid blocking device comprises a mounting window blocking thermal-insulation board assembly; the mounting window blocking thermal-insulation board assembly is slidably arranged on a limiting transverse plate assembly in a sleeving manner. When the rapid plugging device is used, the device is hold through a handhold pipe assembly, an inner fixed rotating buckle limiting transverse plate is rotated by rotating a blocking rotating handle, the inner fixed rotating buckle limiting transverse plate is rotated to the diagonal direction of a mounting window inner layer blocking thermal-insulation board; and during blocking, the mounting window inner layer blocking thermal-insulation board extends into the position of a furnace wall window; the mounting window outer layer blocking thermal-insulation board is tightly attached to the outer wall of the furnace body window; the blocking rotating handle is pushed forwards and rotated, forward movement and rotation of the inner fixed rotating buckle limiting transverse plate are achieved; and the inner fixed rotating buckle limiting transverse plate is buckled to the inner wall of the furnace body window through jacking of a blocking and jacking spring.

Description

technical field [0001] The invention belongs to the technical field of hot-end manufacturing of substrate glass, and in particular relates to a fast sealing device for an installation window of a substrate glass forming furnace. Background technique [0002] In the process of producing substrate glass by the overflow down-draw method, after the glass liquid is filled in the overflow tank of the overflow brick, it flows from the top of the tank along the two side walls of the overflow brick to the inclined wall, and finally in the overflow brick The tips are brought together to form a glass ribbon, and the glass ribbon is formed under the pull-down effect of gravity and the pulling and pulling of equipment such as edge pulling machines and pulling rollers. Outside the forming furnace and annealing furnace, the edge pulling machine shaft and the pulling roller shaft extend into a certain position inside the furnace cavity through the special installation window of the furnace ...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following problems: in the known prior art, the thermal insulation blanket that wraps the thermal insulation cotton with the velvet cloth and sews is used to block the edge pulling machine and the installation window of the traction roller, but on the one hand, the thermal insulation blanket lacks an effective Fixed and supported, the risk of loosening and falling is high; on the other hand, the extrusion and sealing speed of the insulation blanket is slow, the sealing performance is poor, and it is easy to be damaged after high temperature aging, and the cost of spare parts is high
