Glass liner annealing furnace

Abstract

The invention provides a glass liner annealing furnace which can balance the amount of heat received by a direct heating surface and an indirect heating surface of the glass liner when the glass liner passes through a furnace chamber. The glass liner annealing furnace comprises a frame and a furnace body arranged on the frame, wherein a combustion chamber and a furnace chamber above the combustion chamber are arranged in the furnace body, two ends of the furnace body are provided with a furnace body inlet and a furnace body outlet respectively, a discharge flue communicated with the furnace chamber is formed through the top of the furnace body, a thermal insulation passage communicated with the furnace chamber and encircled by a thermal insulation layer which is composed of a thermal insulation material is arranged in the furnace body, the distance between a side wall of the furnace chamber close to one side of the thermal insulation passage and the furnace body inlet is greater than the distance between a side wall of the combustion chamber close to one side of the thermal insulation passage and the furnace body inlet, the discharge flue is next to the side wall of the furnace chamber close to one side of the thermal insulation passage, and a conveying device for conveying glass liners is arranged on the frame. The glass liner annealing furnace provided by the invention is particularly suitable for eliminating internal stresses generated in the manufacturing process of various hollow glass liners.

Description

technical field [0001] The invention relates to an annealing furnace, in particular to a bottle liner annealing furnace. Background technique [0002] The bottle liner annealing furnace is used to eliminate the internal stress generated in the manufacturing process of glass bottles. [0003] During the use of the current bottle liner annealing furnace, when the bottle liner passes through the furnace cavity above the combustion chamber, the degree of heating between the direct heating surface on the side facing the combustion chamber and the indirect heating surface on the other side away from the combustion chamber Different, there is a temperature difference between the two sides, which makes the whole glass bottle heated unevenly and affects the annealing effect. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a bottle liner annealing furnace that can balance the heat received by the direct heating surface an...
