Abstract
The utility model relates to a long-range reset button of blast furnace sluicing rotary drum converter utilizes the spare line of reset button in the rotary drum frequency conversion cabinet, inserts programmable controller promptly PLC cabinet's output relay with the reset key binding post of rotary drum converter on, carries out picture configuration programming again on the host computer of main control room, with access point and operation picture and the keying connection that resets. When the frequency converter of the rotary drum has power-off or failure reporting, remote and timely reset can be realized on an operation picture of the slag flushing main control room, so that the fault rate of the rotary drum and the damping down time of the blast furnace are reduced, the manpower and economic losses caused by untimely reset are avoided, and the annual saving value is more than 20 ten thousand yuan.
Description
Technical field
The utility model belongs to automation field, is specifically related to a kind of reset button that blast furnace slag flushing rotary drum frequency transformer carries out Long-distance Control that is used for.
Background technology
Rotary drum is the key equipment of the whole flushing cinder of blast furnace system, and it is that PLC controls that present rotary drum Controlling System generally adopts frequency transformer and programmable controller.Because the required place of blast furnace is bigger, therefore general rotary drum frequency transformer is all far away relatively apart from the flushing cinder master control room, in the punching out process, in case the rotary drum frequency transformer is jumped electricity or newspaper fault owing to inner reason causes, all needing operator to go to far electric panel room carries out resetting by the machine, both inconvenient, waste time and energy again.Reset if especially frequency transformer is untimely, will cause rotary drum to advance red slag or kill, blast furnace also will be forced to stifled big gun or damping down.According to statistics, because of the rotary drum frequency transformer resets the untimely blast furnace staying that causes more than twice, each damping down reaches 2 hours, has not only increased the workload and the difficulty of accident treatment every year on average, simultaneously also directly influence carrying out smoothly of blast furnace production, cause greatly financial loss.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple, can in time reset at flushing cinder master control room inner control rotary drum frequency transformer, reduces the rotary drum failure rate, guarantees the remote reset button of blast furnace production direct motion.
For this reason, the solution taked of the utility model is:
A kind of blast furnace slag flushing rotary drum frequency transformer remote reset button, utilize the reset button spare wire in the rotary drum frequency conversion tank, with the reset key connection terminal access programmable controller of rotary drum frequency transformer is on the output relay of PLC cabinet, on the master control room upper computer, carry out the picture configuration programming again, access point is connected with operation screen and reset key.
Owing to taked above-mentioned mode of connection, make the rotary drum frequency transformer in case electricity occurs jumping or the newspaper fault, can be on flushing cinder master control room operation screen immediately show and can realize long-rangely in time resetting, not only convenient but also quick, save electric panel room and carried out the other time that resets of machine, reduce the rotary drum failure rate, improved operation rate of blast furnace, avoid because reset untimely manpower that causes and financial loss, concerning large blast furnace, year save be worth 20 surplus ten thousand yuan.
