The invention uses platinum as the work pool for preventing glass from polluting. The bottom of the work pool is connected with the platinum heating system, the glass can be directly performed ohmic heating through the platinum discharging pipe to obtain the glass liquid with good temperature uniformity. The process of direct ohmic heating platinum avoids the heat loss caused by radiation, and no exhaust gas is generated, the heating system is energy saving and environmental protection.

Description

technical field [0001] The invention relates to a platinum heating system in glass manufacturing, which belongs to the field of glass manufacturing. Background technique [0002] In the existing glass production and manufacturing, there are two main ways to control the glass forming temperature and output volume: [0003] 1. The method of using the material basin and the uniform barrel: [0004] Silicon carbide rods are used to heat the material basin, and the power of the silicon carbide rods is adjusted to control the glass discharge temperature. Some manufacturers also install natural gas burners on the material basin, and control the glass discharge temperature by adjusting the amount of natural gas and combustion-supporting air. The temperature of the glass inside the cylinder should be as uniform as possible. The homogenizing cylinder is designed with a lifting device, which controls the cross-sectional area of ​​the glass flow through the lifting of the homogenizin...

Problems solved by technology

[0005] The disadvantage of this method is: the temperature of the glass discharge depends on the indirect heating method, and the temperature response hysteresis is obvious; in addition, since the homogenizing cylinder is made of refractory material, the refractory material is eroded by the glass liquid and enters the glass, contaminating the glass and reducing the quality of the glass; The service life of the uniform barrel is short, and the general service life is one to two months

This method also has the disadvantages of the first method. In addition, the height of the gate brick is not easy to control
