Description

Technical Field

[0001] The invention relates to the field of glass production equipment, in particular to a positioning and installation device for an upper air duct inside an annealing furnace. Background Art

[0002] Glass is mainly annealed in the annealing furnace. The stability of temperature control has an important impact on the yield and quality of glass. The main methods for adjusting temperature stability are heating with electric heating, cooling with a cooling air system (external fan, external air duct, internal upper air duct), and controlling sudden temperature changes with an insulation layer.

[0003] The installation of the internal upper air duct and the internal upper air duct bracket of the annealing furnace directly affects the use of the annealing furnace. The annealing furnaces on some glass production lines have experienced problems such as internal upper air duct breakage, temperature control difficulties, and reduced yields due to unqualified installation of the internal upper air duct. How to complete the precise positioning and installation of the internal upper air duct plays a vital role in the efficiency of the external fan and the temperature control of the annealing furnace.

[0004] The traditional adjustment method is: first, all the shells of each zone (including the first kiln body, several intermediate sections, and the last kiln body) are placed on the shell welding platform; the upper air inlet box and the upper air outlet box of the internal upper air duct are hoisted into the first kiln body and the last kiln body respectively, and are positioned and installed with a tape measure according to the center of the kiln body; a straight line is drawn from the upper air inlet box to the upper air outlet box with a wire rope, and the hanging plate A and the roller shaft of the upper intermediate air duct are positioned and installed, and the positioning is completed by measuring the upper and lower front and rear distances with a triangle ruler; this positioning and installation method relies on wire pulling (the front and rear shells of the annealing kiln are positioned with a wire rope), measurement (measuring the distance between the internal upper air duct and the wire rope), adjustment (moving the position of the internal air duct to make the distance uniform by visual inspection), etc., which is inefficient and low in accuracy.
