The invention provides a dust-free heating furnace body, which comprises a furnace wall, characterized in that the furnace wall is divided into an inner layer, a middle layer and an outer layer from the inside to the outside, the middle layer is located in the gap between the inner layer and the outer layer, the inner layer is a ceramic sheet, the outer layer is a steel plate, and the middle layer is a ceramic fiber cloth bag filled with ceramic fiber cotton. The ceramic fiber cloth bag is cuboid, and the two sides of the ceramic fiber cloth bag are respectively close to the inner layer and the outer layer. In the high temperature furnace, ceramic fibers are blocked in the middle layer of the furnace wall by ceramic thin plates. There is no high temperature contact between ceramic fibers cotton and the furnace. Therefore, crystallization and pulverization will not occur, and the inner wall of the furnace will not be covered with dust due to crystallization and pulverization, thus polluting the environment of the furnace.
【技术实现步骤摘要】
一种无尘加热炉的炉体
本专利技术属于加热炉
,涉及一种无尘加热炉的炉体。
技术介绍
现有的加热炉只有两层结构,内层采用陶瓷纤维毡来为内壁,陶瓷纤维毡具备隔热效果,而外层则用钢板。陶瓷纤维毡采用陶瓷纤维压制而成,在长期高温环境下,陶瓷纤维会发生结晶粉化,导致炉膛内布满粉尘。
技术实现思路
本专利技术的目的是针对现有的技术存在上述问题,提出了一种无尘加热炉的炉体,采用陶瓷薄板来阻隔陶瓷纤维,防止陶瓷纤维结晶粉化,提高了炉体内的洁净度。本专利技术的目的可通过下列技术方案来实现:一种无尘加热炉的炉体,炉体包括炉壁,其特征在于,所述炉壁由内到外分为内层、中层、外层,中层位于内层和外层的间隙中,所述内层为陶瓷薄板,所述外层为钢板,中层为填满陶瓷纤维棉的陶瓷纤维布袋,所述陶瓷纤维布袋呈长方体,陶瓷纤维布袋的两侧面分别与内层和外层相贴靠。进一步的,所述的陶瓷薄板的厚度为5mm~10mm。进一步的,所述内层与外层之间间隙为20mm~30mm。进一步的,陶瓷纤维布袋具有袋口,填满陶瓷纤维棉后由陶瓷纤维绳把袋口扎紧封住。与现有技术相比,在高温的炉体中,通过陶瓷薄板将陶瓷纤维阻隔在炉壁 ...
