Description

一种喷嘴和保护套的卡托结构 技术领域
本实用新型涉及喷嘴与保护套保护技术领域，具体涉及一种喷嘴和保护套的卡托结构。
背景技术
在高温加热装置中，常用从顶部伸入式的加热枪体，加热枪体需从加热装置的上方伸入高温内腔中。加热枪体多使用金属材料进行制作。为了能在高温条件下长期使用且不损坏，常用方法是对加热枪体通水冷却。而通水冷却虽然保护了设备，但是会导致高温内腔的热损失。同时加热枪体虽然有了冷却保护，但是外表面仍然有可能因高温导致的局部损坏造成不能长期使用，因此需要在加热枪体的外侧使用耐高温保护套。一般的保护套使用丝口外挂固定，但是陶瓷保护套处于高温环境下，加热枪体采用水冷保护，保护套的两侧极大的温度差极易使得保护套的陶瓷挂丝断裂而造成脱套。当采用在加热枪体外固定的金属环卡托结构时，其固定结构与加热装置多为丝口连接，会因导热不好而导致金属环损坏，最终影响到保护套的使用。
发明内容
本实用新型目的是提供一种喷嘴和保护套的卡托结构，解决了现有技术中加热枪体外的固定结构损坏而影响保护套的使用的问题，能够为加热枪和喷嘴提供更好的保护。
为实现上述目的，本实用新型采用以下技术方案:
一种喷嘴和保护套的卡托结构，包括加热枪和喷嘴，所述加热枪的下端与喷嘴连接，所述加热枪和喷嘴的外侧设置有保护套，所述喷嘴的外侧设置有一体式的外凸卡托，所述保护套与外凸卡托配合形成卡托结构，在保护套与卡托结构以及加热枪与喷嘴之间具有间隙。
可选的，所述保护套为无卡口直管或内凹卡口直管。
可选的，所述保护套的材质为陶瓷材料或石墨材料。
可选的，所述保护套为无卡口直管，所述喷嘴的外侧设置的外凸卡托支撑在无卡口直管的下方，形成托住保护套的卡托结构。
可选的，所述保护套为内凹卡口直管，所述喷嘴的外侧的外凸卡托支撑在保护套的内凹卡口内，形成托住保护套的卡托结构。
可选的，所述外凸卡托的形状为圆环，或将圆环进行切割后保留的部份。
可选的，所述加热枪的外侧与保护套之间设置有保温材料，所述保温材料为耐火毡或多孔状耐高温陶瓷材料。
本实用新型相对于现有技术，具有以下有益效果：
本实用新型通过喷嘴上设置一体式卡托结构，使得保护套能够更好的保护结构主体，在保护套与卡托结构和需保护加热枪与喷嘴之间需预留间隙，以避免在高温条件下，各部件因热膨胀导致的尺寸变化而影响结构的稳定性。
附图说明
图1为本实用新型实施例的剖视图。
图2为本实用新型实施例的外凸卡托的结构示意图。
图中所示：喷嘴-1，加热枪-2，保护套-3，外凸卡托-4，内凹卡口-5，保温材料-6。
具体实施方式
下面结合附图1和2对本实用新型作进一步描述。
如图1和2所示的喷嘴和保护套的卡托结构，包括加热枪2和喷嘴1，所述加热枪2的下端与喷嘴1连接，所述加热枪2的一端和喷嘴1的外侧设置有保护套3。所述喷嘴1的外侧设置有一体式的外凸卡托4，所述保护套3与外凸卡托4配合形成卡托结构。在保护套3与卡托结构4和需保护的加热枪2的枪体与喷嘴1之间具有间隙，以避免在高温条件下，各部件因热膨胀导致的尺寸变化而影响结构的稳定性。所述加热枪2的枪体外侧与保护套3之间设置有保温材料6，所述保温材料6包括耐火毡或多孔状 耐高温陶瓷材料。
所述保护套3为陶瓷材料或石墨材料。保护套3可以为无卡口直管，或有内凹卡口的直管。当所述保护套3是无卡口直管时，喷嘴1的外侧设置的外凸卡托4支撑在无卡口直管的下方，形成托住保护套3的卡托结构。当所述保护套3是内凹卡口直管时，所述喷嘴1的外侧的外凸卡托4支撑在保护套3的内凹卡口5内，形成托住保护套3的卡托结构。
如图2所示，所述外凸卡托4的形状为圆环，或将圆环进行切割后保留的部份，从而既起到卡托的作用，又减少受热面。切割的形状在不影响喷嘴1的本身结构与卡托4的支撑作用下可以任意切割形状。
以上所述仅为本实用新型的优选实施例而已，所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述,术语“设置”、“安装”、“连接”、“固定”等术语应做广义理解，对于本领域的技术人员来说，本实用新型可以有各种更改和变化。凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
