Stirring station of underground lime material of coal mine

煤矿井下灰料搅拌站

Abstract

本实用新型公开了一种煤矿井下灰料搅拌站,它包括安装在井下备料处的一台卧式搅拌机和一台上料机,其中卧式搅拌机和上料机的动力分别采用22kW防爆电机和7.85kW防爆电机,在卧式搅拌机的出料口安装有负压除尘罩和由气动司控器控制的气动下料门,防爆电机采用QBZ-80N真空开关远程控制。本实用新型可以使井下灰料进行集中搅拌处理,两名人员操作就可以满足井下掘进工作面喷浆用料的任务,避免了产生灰尘,净化了井下工作环境;并且达到了灰料科学配比,使掘进迎头喷浆回弹少,保证了巷道的支护质量。
The utility model discloses a stirring station of an underground lime material of a coal mine, which comprises a horizontal type stirrer and a material charging machine, wherein the horizontal type stirrer is installed at an underground material preparation position, the power of the horizontal type stirrer and the material charging machine respectively adopts an explosion-proof motor of 22kW and an explosion-proof motor of 7.85kW, a discharge port of the horizontal type stirrer is provided with a negative-pressure dust removal cover and a pneumatic blanking door which is controlled by a pneumatic control device, and the explosion-proof motors are remotely controlled by adopting a QBZ-80N vacuum switch. The utility model can carry out concentrated stirring treatment on the underground lime material, can meet the task of a guniting material of an underground excavation working face only by two workers, avoids generating dust and purifies an underground working environment; and moreover, the scientific mixture ratio of the lime material is achieved, the rebound of head-on excavation guniting is little, and the supporting quality of a laneway is ensured.
