Abstract

本实用新型提出的套装玻璃钢风筒,属于矿井局 部通风用导风筒,是由若干个锥形筒体连接而成,每 个锥形筒体两端均有一圈沟槽,筒体之间用卡环、密 封带和螺栓、螺母密封固定。每个筒体的直径均不相 等,当搬运贮存时,将卡环、密封带取下,筒体可依直 径大小套装起来,提高了运输量,减少了运输费和贮 存库房。

Description

本实用新型涉及一种矿井局部通风用的风筒。
在矿井坑道中,局部通风使用的玻璃钢风筒,是一种圆柱形筒体,筒体两端有法兰盘,筒体之间用螺栓、螺母连接,这种风筒的缺点是运输、存放占用空间大,增加了运输费用和存放库房。
本实用新型的目的在于克服现有技术中所存在的缺点,而提出一种有利于运输和存放的套装玻璃钢风筒。
本实用新型是由筒体、密封带、卡环和螺栓、螺母组成,筒体为圆锥形,两端各有一圈沟槽,筒体之间的连接为搭接,在结合部用密封带缠绕一圈,外用两个瓦圈形卡环压住,用螺栓、螺母紧固。当搬运或存放时,将卡环、密封带取下,筒体按直径大小套装在一起。
本实用新型的优点是搬运、存放时可以套将装在一起,减少了占用空间,提高了运输量,降低了运输费,减少了占用库房。
图1为本实用新型的结构示意图
图2为卡环的结构示意图
图3为图2的俯视图
筒体(1)是用玻璃钢制做的圆锥形筒体,锥度为1:100,筒体壁厚4-6毫米,在两端各有一圈沟槽;卡环(2)是由瓦圈形环体(7)和环耳(6)组成,环体的宽度为50-60毫米,环体的两帮高度相差6-8毫米;密封带3是采用耐油橡胶制造,厚2毫米,宽40毫米。
本实用新型是由若干个筒体连接而成的,每个筒体的锥度、长度相同。直径都不相等。第一个筒体的大端放进第二个筒体的小端,第二个筒体的大端放进第三个筒体的小端,这样依直径大小接下去,筒体之间的结合部位用密封带包一圈,外用两个卡环压住,卡环的两帮分别卡入两筒体的沟槽内,在两个卡环的环耳上,穿上螺栓(4)、拧紧螺母(5),使卡环压紧筒体,当搬运、存放时,取下螺栓、螺母、卡环、密封带,将筒体按连接的顺序套装在一起。

Claims (4)
