Description

Technical Field

[0001] The utility model belongs to the technical field of glass tempering furnaces, and particularly relates to a fan structure of a glass tempering furnace. Background Art

[0002] Ordinary glass has low strength, which makes it very easy to break during processing or transportation. In order to improve the tensile strength and impact resistance of glass, a glass tempering furnace is required during the production process to heat the glass surface at high temperature and then cool it rapidly to generate compressive stress on the glass surface and tensile stress inside.

[0003] Some glass tempering furnaces use radiation plates to heat the glass. The radiation plates are located below the glass. When the glass enters the glass tempering furnace at room temperature, the radiation plates radiate and transfer heat to the glass so that the glass obtains heat. The problem is that the glass tempering furnace with the above structure uses several groups of radiation plates to heat the glass, and there are large gaps between the radiation plates, which will cause uneven radiation to the glass. The temperature between the radiation plates is not transferred, resulting in uneven heating of the glass and deformation, affecting the processing quality of the glass, resulting in a high defective rate of the glass, and increasing the production cost of the glass.

[0004] In addition, the glass tempering furnace usually adopts a convection circulation fan to blow hot air to the glass to achieve heating of the glass. The convection circulation fan generally adopts a turbine volute fan. When the glass tempering furnace heats the glass, the hot air of the turbine volute fan is output through the volute outlet in turn and enters the wind grid, and is blown to the glass surface through the wind grid outlet to allow the glass to gain heat. The problem is that the glass tempering furnace with the above structure has a small size of the volute outlet, and the flow rate of hot air entering the wind grid is small, resulting in uneven hot air in each wind grid, resulting in uneven heating and deformation of the glass, affecting the processing quality of the glass, and the wind pressure blown out of the wind grid outlet is low, resulting in poor heating efficiency of the glass, greatly extending the heating time of the glass, and reducing the production efficiency of the glass.

[0005] Therefore, further improvement is needed. Utility Model Content
