Fusion sealing process and device for glass sealing connector

Abstract

The invention belongs to the technical field of glass production, and discloses a fusion sealing process and device for a glass sealing connector, and the fusion sealing process comprises the following steps: 1, before use, respectively putting two glass bodies to be combined into two connecting molds, and simultaneously separating the two connecting molds to be connected; secondly, an oxygen tank and a hydrogen tank are connected with an oxygen connector and a hydrogen connector at the same time. The original heating mode is changed by mixing hydrogen and oxygen, the hydrogen is combined with the oxygen by utilizing the flammable and combustible characteristics of the hydrogen, the oxygen provides a combustion environment for the hydrogen, the high temperature of more than 500 DEG C can be quickly reached after the hydrogen is ignited, and the temperature completely meets the temperature during glass melting, so that the glass melting efficiency is improved. Compared with the prior art, the glass can be rapidly heated to avoid long-time waiting, meanwhile, due to the fact that mixed combustion of two kinds of gas is adopted, electric energy and other energy consumed in the traditional heating process are abandoned, the consumed cost is low, and then the actual production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a melting and sealing process and device for a glass sealing connector. Background technique [0002] Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary materials are added. Yes, its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with irregular structure. The kinetic energy of the thermal motion increases, resulting in the destruction of crystallization, and the process of changing the material from the crystalline phase to the liquid phase; it is a first-order phase transition, with an increase in ...

Problems solved by technology

[0003] The common glass melting process mainly includes three major steps, that is, firstly heat the two glasses to be combined, position them after the two glass bodies have reached the melting temperature, and then combine them, and then cool them after the combination is completed. After the cooling is completed, two combined glass bodies can be obtained. However, there are many problems when using this process for glass melting. Since the melting temperature of ordinary glass is generally about 500 degrees, when the glass reaches the melting temperature, electricity is generally used. The glass is heated to the melting temperature by means of furnace or furnace fire. Obviously, it takes a lot of time to heat the glass from the melting temperature at room temperature. At the same time, it needs to consume a lot of energy during the heating process, resulting in a significant increase in production costs. At the same time, because of heating Excessive time will cause a decline in production efficiency

[0004] In the glass melting process, after the glass is heated to the predetermined melting temperature, it needs to be positioned quickly and the two glasses are bonded together. In the prior art, the transmission device of the cylinder or the motor is generally used to drive the two connecting molds to complete the positioning. and combined with each other, but due to the high temperature during melting, when using a motor or cylinder for transmission, the working environment will be affected by high temperature for a long time, which will easily affect the service life of the equipment. At the same time, the cylinder or motor is used for positioning and The combination requires a certain reaction time and transmission time. Too long a reaction time will cause a decrease in the quality of the melt, which cannot achieve rapid positioning and combination, and is prone to failure.

[0005] After the two glass bodies are combined, in order to obtain the finished glass body as soon as possible, it is often necessary to cool the glass body. The common cooling methods are generally natural air cooling and water cooling. The former needs to rely on air to take away heat, which requires more energy. time, while the latter requires more cooling water to cool down the glass body, and at the same time, the temperature of the cooling water keeps rising during use. It will waste a lot of water resources, which is not conducive to the policy of energy saving and environmental protection
