Problems solved by technology
However, the vacuum hood uses a steel wire hose to adjust the position, which is complicated to operate and high in cost, and it is impossible to avoid the overflow of smoke through the sprue during pouring, and there are still problems of low smoke efficiency and high air leakage rate

The invention provides a steel ladle bottom pouring smoke dust collecting system and a smoke dust collecting method, and belongs to the field of smoke dust collection in the casting industry. The smoke dust collecting system during steel ladle bottom pouring involves a smoke exhaust main pipeline, a butt joint valve, a ladle bottom pouring collecting cover, a travelling rail and a reserved openingsealing device; the ladle bottom pouring collecting cover comprises a first independent collecting cover body and a second independent collecting cover body, and during pouring, the two independent ladle bottom pouring collecting cover bodies are in butt joint into a whole and are symmetrical along the butt joint face. According to the pouring smoke dust collecting system, by improving the designand the sealing mode of the dust suction cover and matching with switching of the butt joint valve, a small sealing space can be formed at a pouring station, the sealing performance is good, and compared with a top suction cover, the air volume needed by dust removal can be greatly reduced, and the collecting efficiency is greatly improved. Compared with the scheme of isolating a whole pouring workshop, more energy is saved, and the operability is better.
Description
technical field [0001] The invention belongs to the field of dust collection in the foundry industry, and in particular relates to a dust collection system and a dust collection method for ladle bottom pouring. Background technique [0002] In the pouring process of large castings in the foundry industry, it is necessary to use the crane to hang the ladle for pouring. The ladle leaks molten steel into the sand box or mold through the pouring valve at the bottom of the ladle. A large amount of smoke and dust will be generated during the pouring process, mainly molten steel Splashing dust caused by falling, dust generated by gasification of sand box cores, smoke dust and volatiles generated by heating molding sand, a large amount of smoke dust leads to poor pouring site environment, so smoke dust needs to be collected. [0003] Most of the existing pouring ladle bottom pouring collection covers are top-suction, side-suction and semi-enclosed mobile. However, due to the need fo...
