Description

一种灭火装置内筒 技术领域
本发明属于气溶胶灭火技术领域， 特别是一种灭火装置的内筒。
背景技术
火灾的发生， 常常给人们的生命和财产造成重大损失。 合适的消防设 备对将火灾消灭在萌芽之中是必不可少。 但是不同的场所对消防设备的要 求是不同的。 在现代工作和生活环境中， 交通运输工具、 电子设备、 家用 电器、 厨房等相对狭小的场所， 普通的灭火装置就能够有效解决灭火问题， 但是对于空间更狭小如 3~15立方的小空间中， 如配电柜、 小型无人值守基 站等应用场所， 若使用现有的灭火装置， 其往往灭火效能低下， 而且会产 生对人体或者其他物品的危害。
另外， 现有的灭火装置内筒一般在冷却剂前面没有任何隔挡的东西设 置， 致使药柱引燃后， 产生的热气溶胶气体会从喷口喷出， 这个过程中将 会带出部分冷却剂， 使得喷口堵塞或者降低热气溶胶的灭火性能。 而且在 搬动运输过程中冷却剂极容易塌陷。 还有， 现有的灭火装置设置有喇叭喷 口， 但是被点焊到前盖上的喇叭喷口在筒体前端容易偏位倾斜， 从而导致 热气流容易聚积， 引起筒体前端产生局部温度过高， 而且点焊质量的一致 性不好， 外观难看。
发明内容
为了解决上述现有技术存在的缺陷， 本发明提供了一种喷口一体化、 便于安装的灭火装置内筒。
本发明所采用的技术方案是： 一种灭火装置内筒， 包括内筒体 （2)、 设置于内筒体 （2) 前端且中部开有喷口 （9) 的内筒盖 （3 ) 以及依次设置 于内筒体（2) 内的喇叭喷嘴（7 )、冷却剂（4)、 药柱（6)、 设置于药柱（6) 前端面的点火头 （10) 和设置于药柱 （6) 与内筒体 （2) 内之间的保温隔 热层 （5 ) ； 其特征在于： 该喇叭喷嘴 （7) 与内筒盖 （3 ) —体化设置， 且 其中心与喷口 （9) 中心正对； 这样不需要再对喇叭喷嘴与喷口进行焊接， 简化了加工工艺， 而且便于内筒装配。
本发明的内筒体底部外壁上设置有限位台 （11 )， 其中限位台 （11 ) 的 外壁与灭火装置的壳体内壁适配； 这样， 当内筒体安装到灭火装置外壳体 内时， 外壳底部相关结构正好卡住内筒底部的限位台， 这样内筒在轴向就 被确切定位， 而且安装方便。
本发明的冷却剂（4)的前端和 /或者中段还设置有陶瓷蜂窝冷却层（8)， 根据冷却剂量得多少来确定其位置， 其可以固定冷却剂， 防止其结块或塌 陷， 另外冷却效果好， 蜂窝冷却层导热效果好， 能够起到散热、 降温的作 用。
本发明的喷口 (9)采用橡胶塞 (12)密封。
本发明的灭火装置内筒， 其具有以下优点：
第一， 本发明采用喷口与喇叭喷嘴一体化设计， 一次成型， 简化了加 工工艺， 便于内筒装配。
第二， 本发明的内筒体底部外围设置有限位台， 这样， 当内筒体安装 到灭火装置外壳体内时， 外壳底部相关结构正好卡住内筒底部的限位台， 这样内筒在轴向就被确切定位， 而且安装方便
第三， 本发明的冷却剂通过陶瓷蜂窝冷却层隔挡， 能够固定冷却剂， 防止冷却剂掉出并有物理冷却的作用， 使得引燃的药剂可以有效发挥灭火 功效， 大大提高了灭火效能， 而且降低了其喷发后可能对人员、 电气及其 它室内物品而产生的危害和腐蚀； 主要是利用陶瓷结构强度及刚度好、 吸 热、 贮热效果好的特性。
第四， 本发明的喷口处理简单， 采用橡胶塞密封， 使得结构美观而且 简化了工艺。
附图说明
图 1为本发明的内筒结构示意图；
图 2为本发明的内筒体剖视图；
图 3为本发明的喷口结构示意图。
图中： 1-内筒， 2-内筒体， 3-内筒盖， 4-冷却剂， 5-保温隔热层， 6-药 柱， 7-喇叭喷嘴， 8-陶瓷蜂窝冷却层， 9-喷口， 10-点火头， 11-限位台， 12- 橡胶塞。
具体实施方式
本发明的灭火装置内筒， 其较佳的实施方式是： 参见图 1至图 3， 本发明的内筒 1包括内筒体 2、 设置于内筒体 2前端 的内筒盖 3以及依次设置于筒体内 2的喇叭喷嘴 7、 陶瓷蜂窝冷却层 8、 冷 却剂 4、 药柱 6和设置于药柱 6前端面的点火头 10; 通常将内筒体 2与内 筒盖 3采用密封连接， 参见图 2， 在内筒盖 3上还设置有喷口 9， 喷口 9采 用橡胶塞 12或箔铝纸密封且喷口 9与喇叭喷嘴 7设置为一体结构， 且其中 心正对； 陶瓷蜂窝冷却层 8可以固定冷却剂 4且能够防止冷却剂 4掉出， 并有物理冷却的作用； 可以将其设置在冷却剂 4前端， 如图 1， 也可以将其 设置在冷却剂 4前端和中间处， 或者还可以设置在冷却剂 4的前端和中段 靠近药柱一端的三分之一处， 可以是一个， 也可以是多个， 根据实际应用 情况确定其位置及数目； 药柱 6与内筒体 2内之间还设置有保温隔热层 5， 起保温隔热的作用， 防止气溶胶引燃后的热量散发烧伤周围的人员或物资。
本发明为了安装方便在内筒体 2的底端外围还增设了限位台 11， 即该 限位台 11的外径最好与灭火装置的壳体内壁相适配， 当内筒体 2安装在灭 火装置的壳体内时， 限位台正好与壳体内壁卡住， 实现对内筒体 2限位， 防止其在壳体内晃动或者摇动， 从而影响灭火装置的灭火效能。
通常当药柱 6的药剂被点火头 10处引燃后， 发生燃烧反应， 产生热气 溶胶灭火气体，热气溶胶灭火气体通过冷却剂 4的冷却降温后在喇叭喷嘴 7 的引流作用下顺着喇叭喷嘴 7出口处的喷口 9喷出， 达到灭火的目的， 且 喷口温度较低。
上述仅为最佳实例的描述， 其结构不仅限于此， 仅仅是在形式和细节 上的改动将不影响本装置的实质和保护范围。
