Technical Field
The utility model relates to a smoke and dust updraft ventilator that steel mill used specifically indicates a steel mill ladle and package slidingtype smoke and dust updraft ventilator that removes.
Background
In the production flow of a steel mill, a ladle merging process is carried out, the rising speed of hot smoke in the ladle merging process is very high, so that a ladle receiving molten steel is required to be close to an air draft smoke hood as much as possible, at least one part of the ladle is arranged at the lower part of the smoke hood, and otherwise, hot smoke pollutants generated in the ladle merging process cannot be effectively collected. In the actual operation process, the lifting hook beam for lifting the steel ladle occupies a large space, and the steel ladle cannot be directly lifted and placed at the position required by the exhaust hood due to instability in lifting operation; on the other hand, the swinging parts such as the lifting hook and the like are easy to crash other fixed parts such as the large smoke hood and the like.
Aiming at the problems, the current method for capturing the atmospheric pollutants generated in the process of combining the steel ladles is as follows: the heavy buggy ladle is provided with a fixed large smoke cover and can walk. The working method comprises the following steps: the method comprises the following steps of firstly moving a heavy ladle car to the outside of a fixed cover, hoisting an empty ladle receiving molten steel to the heavy ladle car by a travelling crane, conveying the empty ladle to the working position of a tuyere of a large fume hood by the ladle car, then carrying out a bag combining operation, sucking fume generated in the bag combining process into the large fume hood so as to prevent the inorganization emission of fume pollutants in the bag combining process, returning the empty ladle car to the position outside the large fume hood after the molten steel is packaged by the empty ladle car, and hoisting the empty ladle car by the travelling crane to carry out the next working procedure operation. The main problems with this approach are as follows:
1) the heavy buggy ladle needs to move a certain distance, the body, the track, the hoisting steel wire rope and the like occupy larger working areas and more site positions, and the ladle is easy to crash the cover body during ladle.
2) The device has large investment, in particular to heavy buggy ladle equipment.
3) The travelling movement of the buggy ladle is complex to operate, and particularly the travelling danger of the buggy ladle after being packed is large.
In summary, a steel mill ladle with a sliding type smoke and dust removing exhaust device which occupies a small area, is low in investment, is simple to operate and has a better smoke and dust collecting effect is absent at present.
