Foam pushing device of floatation machine

Pushing the bubble flotation apparatus, to a method for sorting non-ferrous metals, ferrous and non-metallic mineral flotation apparatus, in particular large-bubble flotation machine push means. Characterized in that the push means is a bubble pushing the bubble from the inside cone, and the foam tank extrapolation foam composite cone, double cone structure of the bubble to push the foam outer groove thereof. The apparatus of the present invention, having a push-push to push the foam structure bubble foam tank double cone structure, the froth flotation tank into two near the edge of the slot a foam body is discharged from the overflow tank outside the bubble, and the bubble near the center discharged through the inner foam tank overflow, shorten the transportation distance foam, froth flotation to ensure the successful and timely discharge, conducive to flotation, helping improve the flotation.
