In the drawings, the numerals in the drawings denote the reference numerals and do not denote any particular dimension.
In order to overcome the problems and defects in the prior art and realize the invention purpose of better collecting the dissipated smoke dust generated in the spheroidizing production, the invention adopts the technical scheme that:
as shown in fig. 1, in the environmental-friendly and energy-saving spheroidizing ladle cover device of the invention, a cylindrical structure 6 is arranged on the outer edge of the shell 2, so that the shell 2 becomes a cover cap, and the refractory material 3 is arranged in the inner cavity of the cover cap; a radial gap is formed between the excircle of the refractory material 3 and the inner hole surface of the cylindrical structure 6 of the shell 2; a cylindrical boss 7 is arranged at the central part of the inner end surface (namely the surface of the refractory material 3 facing upwards in the drawing) of the refractory material 3 to be contacted with the inner end surface (namely the surface of the shell 2 facing downwards in the drawing) of the shell 2, and an end surface gap is arranged between the inner end surface (on the same side) outside the cylindrical boss 7 of the refractory material 3 and the inner end surface (on the same side) of the shell 2; the radial gap and the end surface gap form a smoke dust collecting cavity 5; and a dust removal pipe 4 is arranged on the end face of the shell 2 at the position of the end face gap. The dust removal pipe 4 is communicated with a smoke dust collection cavity 5.
The dissipated smoke dust is collected through a dissipated smoke dust collecting cavity 5 formed between the shell 2 and the refractory material 3 in the spheroidizing process, and the dissipated smoke dust is purified through a dust removing pipe 4.
