Description

一种瓦斯抽放管路气水煤分离装置 技术领域
本发明属于水煤分离放水器领域，尤其涉及一种瓦斯抽放管路气水煤分离装置。
背景技术
巷掘进过程中，由于瓦斯涌出量大(达5m 3/min)影响掘进作业的正常进行。为有效降低回风流瓦斯浓度，确保巷道安全掘进，通常在掘进巷道煤帮按一定间隔布置若干预抽钻孔，连接抽放管路、利用抽放泵进行采前预抽。在使用瓦斯抽放管路对钻孔进行抽放过程中，除有煤层气体抽出外，常常伴随有煤渣及裂隙水流出，如不及时处理，一方面造成抽放支管路堵塞，抽放管路不通，导致管路积水等问题；另一方面由于水量增加会影响抽放主管路的负压，造成负压不稳定。
现有的气水煤分离装置包括托盘、侧导向杆、磁铁、中心导向杆、外筒、放水阀保护罩、放水阀、导向座、浮漂、过滤桶等，结构较为复杂，成本较高。此外，气水煤分离装置发生损坏后，更换零部件较为繁琐，且费时费力，耽误气水煤分离。
由此可见，现有技术有待于进一步的改进和提高。
发明内容
本发明为避免上述现有技术存在的不足之处，提供了结构简单，便于操作及更换零部件的瓦斯抽放管路气水煤分离装置。
本发明所采用的技术方案为：
一种瓦斯抽放管路气水煤分离装置，包括耐压方形金属外壳，分离筛板，进气阀，抽气孔，放水阀。
所述进气阀设置在耐压方形金属外壳的左外侧，进气阀与瓦斯抽放管路相连接。
所述抽气孔设置在耐压方形金属外壳的右外侧，抽气孔与瓦斯抽放管路相连接。
所述分离筛板固定在耐压方形金属外壳的内壁上，其中一个固定在外壳前半部分内壁上并与上内壁通过焊接方式紧密连接，另一个固定在外壳后半部分内壁上，且与下内壁有一定间距。
本发明结构简单，设计巧妙，在抽采瓦斯过程中，气和水煤的混合物先从进气阀抽入放水器中，再经过分离筛板后，水煤渣沉积在放水器底部，瓦斯等气体经上方管路口吸走，沉积的水煤渣再由放水阀进行排放，从而完成抽采、分离、放水的作业，进而有效解决了管路堵塞、管路积水、负压不稳定等问题。
由于采用了上述技术方案，本发明所取得的有益效果为：
1、巷掘进过程中，有效降低回风流瓦斯浓度，确保巷道安全掘进，不再在掘进巷道煤帮时按一定间隔布置若干预抽钻孔，连接抽放管路、利用抽放泵进行采前预抽。在使用瓦斯抽放管路对钻孔进行抽放过程中，除有煤层气体抽出外，常常伴随有煤渣及裂隙水流出，本发明彻底解决了抽放支管路堵塞，抽放管路不通，导致管路积水等问题。
2、在安全使用方面，解决了水量增加会影响抽放主管路的负压，造成负压不稳定等问题，安全效果较好。
3、本发明结构简单，设计巧妙，制作成本低，大大提高了瓦斯抽放效率，克服了许多弊端，可在类似煤层瓦斯抽放时推广使用。
