Apparatus for conveying and pre-heating a metal charge for a melting plant and connected method

摘要

Apparatus for continuously conveying and pre-heating a metal charge inside a container of a melting plant, comprising at least a conveyor channel, having walls to convey the metal charge, and at least a hood defining a conveyor tunnel and/or an expansion chamber. The hood is disposed above the conveyor channel for the transit of at least part of the fumes exiting from the container, and the conveyor channel cooperates with apertures to discharge the fumes. The apertures cooperate with at least a fume diverting channel defining at least a first expansion compartment, located substantially vertical or sub-vertical, connected both to the apertures and also to at least a channel to take in the fumes.

1. An apparatus for continuously conveying and pre-heating a metal charge inside a container of a melting plant, comprising:
a container capable of advancing a metal charge; a conveyor channel in fluid communication with said container and having conveyor walls and lateral walls and a bottom wall that define a substantially U-shaped cross section, a hood at least partially disposed above said conveyor channel and having a tunnel wherein at least part of the fumes exiting from the metal charge in said container advance into said hood, at least one fume discharge aperture disposed within said conveyor walls, suction channels disposed within said lateral walls and running substantially the length of the conveyor channel, a fume diverter channel defined by said conveyor walls in cooperation with said lateral walls and capable of passing fumes into said suction channels, and a first expansion compartment connected to said at least one fume discharge aperture and connected to said suction channels; wherein the first expansion compartment is disposed above the conveyor channel.
