我矿2台24米浓密机过去常因矿浆浓度过高、机械阻力太大、轨道不平或电机故障等意外因素出现打滑或停转。在细雨初下、轮轨摩擦力骤降的情况下尤易发生上述现象,若不能及时发现,就会贻误脱滑处理时机,造成搅拌耙齿压死,不得不向事故池排放矿浆,带来环境污染和经济损失。为了解决这个长期存在的难题,我们研制成功1台浓密机打滑报警仪表。该仪表由集成电路无触点接近开关、一套尼龙滚轮及发讯叶片等机械装置组成“运转传感器”,当浓密机处于正常运转状态时即连续发出矩形波检测脉冲,一旦由任何原因(包括各种机电故障)造成的打滑或停转情况发生,上述脉冲即告消失,仪表内电子线路就会在30
My mine 2 24-meter thickener used to slip or stop unexpectedly due to excessive concentration of slurry, too much mechanical resistance, uneven orbital or motor failure. In the early hours of drizzle, the sudden drop in wheel-rail friction occurs particularly prone to the above-mentioned phenomena, if not found in time, it will delaying the slip of the opportunity to deal with, resulting in mixing rake teeth crushed, had to discharge to the accident pool slurry, with To environmental pollution and economic losses. In order to solve this long-standing problem, we successfully developed a thickener slipping alarm instrument. The instrument by the integrated circuit non-contact proximity switches, a nylon wheel and hair foliage and other mechanical devices composed of “running sensor”, when the thickener in the normal operation of the rectangular wave that is continuous detection pulse, once for any reason, including A variety of mechanical and electrical failure) caused by slip or stall occurred, the pulse disappears, the instrument within the electronic circuit will be 30
