Glass product annealing furnace

Abstract

The invention discloses a glass product annealing furnace capable of balancing the heated quantities of the direct heated surface and the indirect heated surface of a glass product while passing through the furnace chamber. The glass product annealing furnace comprises a frame, and a furnace body arranged on the frame, wherein a combustion chamber and a furnace chamber located above the combustion chamber are arranged in the furnace body; a furnace body inlet and a furnace body outlet are formed at the two ends of the furnace body, respectively; a smoke discharge channel communicated with the furnace chamber is formed to penetrate through the top of the furnace body; a thermal insulating channel which is encircled by a thermal insulating layer made of a thermal insulating material and which is communicated with the furnace chamber is further arranged in the furnace body; the distance between the sidewall of the furnace chamber at the side in the vicinity of the thermal insulating channel and the furnace body inlet is larger than that between the sidewall of the combustion chamber at the side in the vicinity of the thermal insulating channel and the furnace body inlet; the smoke discharge channel is arranged close to the sidewall of the furnace chamber at the side in the vicinity of the thermal insulating channel; and a conveying device for conveying the glass products is arranged on the frame. The glass product annealing furnace is especially suitable for eliminating internal stress generated in the manufacture process of various hollow glass products (such as glass bottles).

Description

technical field [0001] The invention relates to an annealing furnace, in particular to an annealing furnace for glass products. Background technique [0002] Glass products (such as: glass bottles) annealing furnace is used to eliminate the internal stress of glass bottles during the manufacturing process. During the use of the current annealing furnace for glass products, when the glass products pass through the furnace cavity above the combustion chamber, the degree of heating of the direct heating surface on the side of the glass product 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 [0003] The technical problem to be solved by the present invention is to provide an annealing furnace for glass products that can balance the he...
