Abstract

The invention relates to the field of glass product production, and discloses a glass bottle annealing cooling device. The glass bottle annealing cooling device comprises a fan, an annealing furnace and a cooling pump. The fan is arranged in the annealing furnace. The fan is fixedly connected with a motor. An exhaust channel is arranged on the annealing furnace. The cooling pump is provided with an air inlet channel and an air outlet channel, and the exhaust channel communicates with the air inlet channel. The air outlet channel communicates with the annealing furnace. The cooling pump is provided with a cooling channel and a cooling cavity, and the cooling channel communicates with the cooling cavity. The upper end of the cooling channel is connected with the air inlet channel. A stop block is arranged at the connecting position of the cooling channel and the cooling cavity, and an air flow channel is formed by the side wall of the cooling cavity and the stop block. An eccentric wheel is rotationally connected in the cooling cavity, a connecting rod is hinged to the eccentric wheel, and a piston is hinged to the end, away from the eccentric wheel, of the connecting rod and arranged in the cooling channel. The lower end of the cooling cavity is connected with the air outlet channel. A heat exchanger is arranged between the cooling cavity and the air outlet channel, and the cooling pump is connected with the motor. Through the glass bottle annealing cooling device, the cooling speed of the annealing furnace can be effectively controlled, and the glass bottle annealing quality is guaranteed.

Description

technical field [0001] The invention relates to the field of glass product production, in particular to a glass bottle annealing cooling device. Background technique [0002] The production process of glass bottles is mainly melting, forming and heat treatment. Melting is to heat the glass production raw materials to a liquid state at high temperature. The bottles are annealed accordingly to relieve the internal stress of the glass bottles. The heat treatment process is divided into heating, heat preservation and cooling stages. The heating is to heat the glass bottle to eliminate the permanent stress inside the glass bottle, then heat preservation to promote the elimination of the permanent stress, and finally to cool it, so as to achieve The purpose of relieving permanent stress. [0003] In some existing annealing devices, in order to ensure the quality of the finished product, the natural cooling method is usually adopted in the cooling stage. Such a production method ...

Problems solved by technology

[0003] In some existing annealing devices, in order to ensure the quality of finished products, natural cooling is usually used in the cooling stage. This kind of production method greatly affects the work efficiency, is relatively backward, and cannot meet the production needs of modern society. In addition, some have cooling function The cooling system of the annealing furnace is usually a cooling fan, which can directly cool the glass bottle by blowing air. However, because the glass bottle still has temporary stress inside after the heating and heat preservation treatment, if the cold air is directly blown on it, the glass bottle will be damaged. If the cooling is too fast, the temporary stress inside the glass bottle will increase. When the temporary stress is greater than the ultimate strength of the glass bottle itself, the glass bottle will burst, which will cause a problem of low yield.
