Description
Technical Field

[0002] In the process of glass production, various materials such as silica sand, silicon dioxide, feldspar, soda ash, metal oxides, sodium sulfate, seawater limestone, dolomite, quartz sand, etc. need to be placed in a heating furnace for heating;
[0003] Most existing heating furnaces have a feed port at the top, and multiple materials are directly fed into the furnace cavity of the heating furnace through a heating port, which causes multiple materials to accumulate in layers inside the furnace cavity, thereby affecting the mixing uniformity between the multiple materials during the heating process, and affecting the mixing effect and mixing efficiency of the glass raw materials during the heating process;
[0004] In addition, the existing heating furnace uses a heating coil structure to heat the furnace cavity of the heating furnace, but the heating coil is mostly a single layer coiled outside the furnace cavity. After the heating medium in the heating coil is exchanged with the glass production raw materials in the furnace cavity, a large amount of heat still exists in the heating medium. Directly discharging the heating medium will affect the utilization effect of the heat in the heating medium.
[0005] In addition, in the process of heating the raw materials for glass production through a heating furnace, it is usually necessary to mix and stir the various raw materials. However, the stirring structure in the existing heating furnace is relatively simple, and most of them use a stirring shaft and a stirring rod. It is impossible to fully stir the various raw materials melted in the heating furnace, which affects the mixing effect and mixing efficiency of the raw materials for glass production.
