Embodiment 1

[0039] Such as figure 1 As shown, a glass pool furnace thermal expansion regulating device of the present invention, figure 1 For the fixed state of the device before the temperature of the glass pool furnace, the glass pool furnace is arranged on the bottom platform, the column 5 is symmetrically arranged on both sides of the glass pool furnace, and the bottom of the column 5 is provided with a fixed wing plate 13, and each two fixed wing plates 13 are respectively It is fixed on the bottom platform on both sides of the glass pool furnace along the thermal expansion movement direction to form a clamping warehouse, which is plugged and matched with the column 5 one by one, and the column 5 and the fixed wing plate 13 are connected and fixed on the bottom platform by the positioning bolt 3 The fixed column 2 is fixedly connected on the bottom platform of the column 5 moving direction, the middle of the fixed column 2 is provided with a threaded hole, the adjusting bolt 1 passes...

Embodiment 2

[0041] Embodiment 2: On the basis of Embodiment 1, this embodiment has made the following optimizations. The bottom of the column 5 is also provided with a bump, and the bottom platform is provided with a sliding groove, and the bump is embedded in the sliding groove so that the column 5 is along the direction of thermal expansion. move.

[0042]The bumps and sliding grooves provided at the bottom of the column 5 ensure the direction of movement during the entire thermal expansion process and improve the stability of the column 5 during the movement.

[0043] A method for adjusting the thermal expansion of a glass pool furnace in the present invention: disassemble the bottom positioning bolt 3, adjust the tightness of the adjusting screw 1 and the loosening of the tie bar 8 by rotating the adjusting bolt 1 and the adjusting nut 12, so that the upright column 5 is under the action of the expansion force down to move.

[0044] In a specific embodiment, the method for adjusting ...

Abstract

The invention discloses a thermal expansion adjusting device for a glass tank furnace. The thermal expansion adjusting device comprises adjusting bolts, fixed columns, a release brace and adjusting nuts, wherein stand columns are symmetrically arranged on the two sides of the glass tank furnace and located and fixed to a bottom platform of the glass tank furnace through locating bolts; the fixed columns are fixedly connected to the parts, located at the outer sides of the stand columns on the two sides of the tank furnace, of the bottom platform respectively; the adjusting bolts are in threaded connection with the fixed columns, and the ends of screws abut against the bottoms of the stand columns on the same side; the two ends of the release brace are provided with threads, penetrate through the upper portions of the stand columns on the two sides of the glass tank furnace respectively and are connected with the adjusting nuts. According to the thermal expansion adjusting device for the glass tank furnace, the bottom positioning bolts are disassembled, and the tightness state of the adjusting screws and the release brace is adjusted by rotating the adjusting bolts and the adjustingnuts, so the stand columns of the glass tank furnace are continuously moved and adjusted, and structural deformation caused by expansion of the glass tank furnace is effectively solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing TFT-LCD glass substrates, in particular to a device and method for adjusting thermal expansion of a glass pool furnace. Background technique [0002] In the glass substrate production industry, the pool furnace is the main heating and melting equipment. The pool furnace is generally made of steel structure as the support, stacked with refractory materials, and then capped with a large wall. The column of the pool furnace is used to support the refractory bricks, and the glass raw materials inside the furnace are heated and melted by natural gas and electrodes. The maximum working temperature of the glass substrate pool furnace is stable at 1600°C. The pool furnace will have a certain expansion effect during the heating stage, and the pool furnace wall and side walls will generate force outward under the action of thermal expansion. Since the column at the bottom of the pool furnace is fixe...
