The utility model discloses an air-sealed rotary kiln with two ends of inner liner, including a rotary kiln base. The upper end of the rotary kiln base is connected with an insulating cylinder body through a connecting rod. The insulating cylinder body is provided with a heating body with an inner liner, the insulating cylinder body is provided with an inner liner, the outer body of the insulating cylinder is provided with a shell cover, and the left side of the insulating cylinder body is provided with a left side between the shell cover. A right air seal structure is arranged between the right side of the heat preservation cylinder body and the shell cover, and the left air seal structure and the right air seal structure are fan-shaped sealing plates. The utility model is characterized in that the movement is completely separated from the stationary parts and relies entirely on gas sealing, i.e. positive or negative pressure atmosphere is formed at the sealing place, the air-cooled parts of the cylinder body on both sides of the shell cover air outlet are equipped with fan-shaped sealing plates, a special blower and several air nozzles are arranged outside, and the air-cooled sleeve is blown to both ends of the cylinder body, according to the technical scheme provided by the utility model, the density is the same as that provided by the utility model. The greatest advantage of the seal is that it has no wear parts, small maintenance and simple structure.
【技术实现步骤摘要】
一种内胆两端气封式回转窑
本技术涉及一种内胆两端气封式回转窑。
技术介绍
回转窑是负压操作的热工设备，在进出料端与静止装置连接处，难免要吸入冷空气，为此必须装设密封装置，以减少漏风。如果密封效果不佳，在热端将降低燃烧温度，增加热耗，在冷端将影响窑内正常通风，加大主排风机负荷。因此，密封性能的好坏，对窑系统的运转和生产指标如产、质量和能耗等，具有重要意义。鉴于筒体弯曲、制造安装误差引起的端面和径向还是轴向都必须留有足够的裕度，因此接触式密封效果不可能令人满意。现在我公司意识到以上问题，对此作出一些改进。
技术实现思路
本技术目的是针对现有技术存在的缺陷提供一种内胆两端气封式回转窑。本技术为实现上述目的，采用如下技术方案：一种内胆两端气封式回转窑，其特征在于，包括回转窑底座，所述回转窑底座的上端通过连接杆连接有保温筒体，所述保温筒体内设置有内置电热丝的发热体，所述发热体内设置有内胆部；所述保温筒体外设置有壳盖；所述保温筒体的左侧与壳盖之间设置有左气封结构，所述保温筒体的右侧与壳盖之间设置有右气封结构；所述左气封结构和右气封结构为扇形密封板。本技术的有益效果：本技术的特点是运动与静止件完全脱离接触，全靠气体密封，即在密封处形成正压或负压氛围，筒体两侧靠紧壳盖出风口的风冷处，装有扇形密封板，外面设有专用鼓风机，若干个空气喷嘴，对着风冷套吹向筒体两端，按照本技术提供的技术方案，这种密封的最大优点是没有磨损件，维修量小，结构简单。附图说明图1为本技术的结构示意图。具体实施方式图1所示，涉及一种内胆两端气封式回转窑，包括回转窑底座6，所述回转窑底座6的上端通过连接杆连接有保...
