Rotary tuyere for blast cupola

The utility model relates to a rotary tuyere for blast cupola, and the rotary tuyere for blast cupola is an improvement compared with the blast tuyere of the existing the cupola. Three rows tuyere connection tubes are mainly welded in the cupola shell, each row tuyere connection tubes deviate from the hearth central angle in different angles, and the tuyeres axes deviate from the hearth center in the same direction. As a result, the cupola gas is ascended in rotary type in the hearth, and the dead space between the adjacent tuyeres can be eliminated. The utility model has the advantages that the coke can be burned fully and uniformly, the coke can be saved more than 30%, and meanwhile, the flow speed is lower, the dust emission concentration is reduced, and the environmental pollution is reduced.
