国内冶金矿山箕斗井装矿站一般采用风动计量装置,用人工集中控制,往往由于操作工误操作而出现计量闸门放矿时装错箕斗的现象,处理事故非常困难.为此我们在云南大姚铜矿箕斗井装矿站的设计中增设了气路连锁,以杜绝计量闸门装错箕斗的事故.气路连锁由曲轨、二通阀、支座组成,如图所示.只有当箕斗在装矿站时,该计量闸门的气路,才能被接通,计量装置才能对箕斗进行放矿.它的动作原理是焊接在箕斗斗箱上的曲轨与二通阀上的滚轮接触,曲轨
Domestic metallurgical mine Mini mine filling station generally used pneumatic measuring device, with artificial centralized control, often due to misoperation of the operator there is the phenomenon of measuring the gate discharge ore when the wrong skip skip, handling the accident is very difficult .Therefore, we in Yunnan In order to prevent accidental installation of false skip, the gas chain is composed of curved rail, two-way valve and bearing, as shown in the figure. Only when the skip at the loading station, the gas path of the metering gate can be connected, the metering device to be able to carry out the dumping of the skip.Its action principle is welded on the bucket hopper curved rail and the two Valve on the roller contact, the track
