Abstract:
1. Apparatus for thermally de-coating and/or drying coated and/or contaminated materials in a batch process, the apparatus comprising: a support having mounting means; an oven pivotally mounted to the support at the mounting means and pivoting through an arc about an axis formed by the mounting means between a reciprocal first position and a second position relative to the mounting means, the oven comprising: a heat treatment chamber; a burner; a recirculation fan; a recirculation chamber; a changeover portion; and a transportable charging portion for carrying the materials from a remote location to the changeover portion; the changeover portion having an open end, an opposing closed end, and an interior with the heat treatment chamber disposed therein and the burner and the recirculation fan and the recirculation chamber attached to the change over portion, said heat treatment chamber disposed between the open end and the opposing closed end of the changeover portion, through which a stream of hot gases heated by the burner are passed, said recirculation fan subsequently passing the gases to the recirculation chamber, said charging portion removably mounted to the change over portion enclosing the open end allowing the materials contained within the charging portion to fall through the open end and through the heat treatment chamber into the interior of the changeover portion in response to the oven pivoting about the axis through the arc.
