Abstract

一种陶瓷成型车间坯体、模型干燥的火焰阻挡装置,具体地说是一种直燃热风炉热风筒挡火帽。所述的挡火帽为圆锥形结构,该挡火帽的锥底内缘大于直燃热风炉热风筒出风口的外圆周,扣接在直燃热风炉热风筒的出风口处。挡火帽的设置,克服了传统直燃热风炉燃烧不充分,引风机寿命低等缺点。该挡火帽结构简单实用,安装挡火帽后,直燃热风炉扩散出的火焰和内筒体内的空气充分接触混合,热量均匀、燃烧更加充分,进而延长引风机叶轮的使用寿命,对操作人员的健康有了极大的改善。

Description

直燃热风炉热风筒挡火帽
技术领域
本实用新型涉及一种陶瓷成型车间坯体、模型干燥的火焰阻挡装置,具体地说是一种直燃热风炉热风筒挡火帽。
背景技术
目前,国内陶瓷生产企业的坯体和模型干燥——直燃热风炉热风筒多为火焰从燃烧机喷向引风机进风口,高温的火苗在没有任何阻挡的情况下直接吹向引风机叶轮,大大的降低引风机的寿命,而且火焰在热风筒内停留时间短、与空气的接触面积小,致使天然气燃烧不充分,浪费能源,并且对操作人员的健康造成了严重的伤害。
发明内容
本实用新型的发明目的在于克服现有直燃热风炉燃料燃烧不充分、引风机使用寿命短等缺点,提供一种结构简单、工作效率高的直燃热风炉热风筒挡火帽。
实现上述目的采用以下技术方案:一种直燃热风炉热风筒挡火帽,所述的挡火帽为圆锥形结构,该挡火帽的锥底内缘大于直燃热风炉热风筒出风口的外圆周,扣接在直燃热风炉热风筒的出风口处。
采用上述技术方案,与现有技术相比,本实用新型挡火帽的设置,克服了传统直燃热风炉燃烧不充分,引风机寿命低等缺点。该挡火帽结构简单实用,安装挡火帽后,直燃热风炉扩散出的火焰和内筒体内的空气充分接触混合,热量均匀、燃烧更加充分,进而延长引风机叶轮的使用寿命,对操作人员的健康有了极大的改善。
附图说明
图1是本实用新型的结构示意图。
图中,1.连接口,2.内筒体,3.散热板,4.出风口,5.挡火帽,燃烧器6。
具体实施方式
下结合附图对本实用新型进一步说明。
本实施例是一种安装在直燃热风炉热风筒上的挡火帽,见图1,所述的直燃热风炉热风筒的连接口1与燃烧器连接,是热风炉的发热部分。其内筒体2是燃气的燃烧室。散热板3套装在内筒体2的外部将内简体2的热量分散带走。所述的挡火帽5为圆锥形结构,其锥底的直径大于热风筒出风口4的外圆周,扣接在热风筒的出风口4处。
热风筒连接口1的燃烧器6喷出的高温火焰在内筒体2中燃烧,在助燃风机的作用下快速冲向挡火帽5,在冲击力作用下沿着挡火帽5的帽沿(锥底)向四周扩散并返回内筒体2,扩散出的火焰和内筒体2内的空气充分接触混合,热量均匀,燃烧更加充分,对引风机叶轮的热损害大大降低,对操作人员的健康和引风机的寿命有了极大的改善。
