基于煤矿井下排水管道结垢特点,采用一种便捷新型除垢工艺,设计了一种新型刮削式除垢装置。该装置通过钢丝绳牵引并通过刮刀刮削管道内壁清理污垢,再利用高压水枪对刮削下来的结垢进行冲洗并排出。该装置具有结构简单、能耗小、成本低廉、除垢效率高的特点,在较深的立井中作业能达到较为理想的效果。 Based on the scaling characteristics of underground drainage pipes in coal mines, a new type of scraping descaling device was designed by adopting a new convenient scale removal process. The device is towed by a steel wire rope and scrapes the inner wall of the pipe by a scraper to clean the dirt, and then the high-pressure water gun is used to wash and discharge the scraped scale. The device has the advantages of simple structure, small energy consumption, low cost and high cleaning efficiency, and the operation in the deep shaft can achieve the ideal effect.
