Glass bottle annealing furnace

Abstract

The invention provides a glass bottle annealing furnace. The furnace comprises a furnace body, the inner chamber of the furnace body is divided into a heating chamber and a cooling chamber, a conveying mesh belt is arranged in the furnace body along the length direction, the conveying mesh belt penetrates through the heating chamber and the cooling chamber, combustion gas heating devices are respectively arranged between the conveying mesh belt and the top of the heating chamber and between the conveying mesh belt and the bottom of the heating chamber, the top of the furnace body is provided with a thermocouple, the thermocouple is connected with a temperature controller through a lead, the combustion gas heating devices are fire lances respectively, each of the fire lances is provided with a gas path control valve, and the conveying mesh belt is wavy. A combustion gas two-sided simultaneous heating mode is adopted, so the heating time is greatly shortened, heating is uniform, and an optical annealing effect is facilitated.

Description

technical field [0001] The invention belongs to the technical field of glass bottle production, in particular to a glass bottle annealing furnace. Background technique [0002] Controlled glass bottles need to be heated and annealed in an annealing furnace after thermoforming to eliminate the internal stress generated during the glass bottle forming process. The existing annealing furnaces mostly use electric heating wires or gas to heat from one side, and the heating time is longer. The glass bottle is heated unevenly, and the thermocouple is not placed at the highest temperature of the furnace, so the measurement error is large, which is not conducive to achieving the best annealing effect for the glass bottle. Contents of the invention [0003] The object of the present invention is to provide an annealing furnace for glass bottles, which is especially suitable for eliminating internal stress after thermoforming of glass bottles. [0004] The technical solution of the ...

[0002] Controlled glass bottles need to be heated and annealed in an annealing furnace after thermoforming to eliminate the internal stress generated during the glass bottle forming process. The existing annealing furnaces mostly use electric heating wires or gas to heat from one side, and the heating time is longer. The glass bottle is heated unevenly, and the position of the thermocouple is not at the highest temperature of the furnace. The measurement error is large, which is not conducive to achieving the best annealing effect for the glass bottle.
