A glass bottle annealing furnace

Abstract

The invention relates to an annealing furnace and particularly relates to a glass bottle annealing furnace, which comprises an annealing furnace and a work bench, wherein the annealing furnace covers the outside of the work bench; a processing part is arranged on the work bench; an air bag is arranged in the processing part; a bump is arranged on the outer surface of the air bag; a two-way flow guide fan is arranged at the upper end of the annealing furnace and comprises a front fan blade and a rear fan blade which are sequentially arranged from bottom to top; an air duct made of metal is arranged in the middle part of the two-way flow guide fan in a penetrating manner; the upper end of the air duct is connected with a blast blower and the lower end of the air duct extends into the air bag; an electric coil is wound on the outer wall of the annealing furnace; a flow guide cover is arranged in the annealing furnace and located at the outer side of the air bag; and a cover bottom is also arranged in the annealing furnace. The problems that the stress strain rates of the inner wall and the outer wall of the glass bottle are different and appearance and the yield of a glass bottle are affected due to fact that the heat dissipation rates of the inner wall and the outer wall of the glass bottle are different are solved.

Description

technical field [0001] The invention relates to an annealing furnace, in particular to a glass bottle annealing furnace. Background technique [0002] Glass is a non-crystalline inorganic substance that melts, cools and solidifies. It has very valuable properties, such as transparency, hardness, good corrosion resistance and heat resistance, and can be made into products of various shapes and sizes by various forming and processing methods. After the glass product is formed at high temperature, different degrees of thermal stress will be generated during the cooling process. These unevenly distributed thermal stress will greatly reduce the mechanical strength and thermal stability of the product, and at the same time have a negative impact on glass expansion, density, optical constants, etc. Influence, so that the product can not achieve the purpose of use. The purpose of annealing glass products is to eliminate or weaken the residual stress, optical inhomogeneity and stabi...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a glass bottle annealing furnace in order to solve the problem that the difference in heat dissipation speed between the inner wall and the outer wall of the glass bottle easily leads to the difference in the stress-strain rate between the inner wall and the outer wall of the glass bottle, which affects the appearance and yield of the glass bottle.
