ROTARY HEAT TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/052495
Kind Code:
A1
Abstract:
Provided is a rotary heat treatment apparatus which can prevent tar or the like from adhering to a sealed portion or a screw casing due to the temperature reducing within a furnace.
A screw conveyor (20) for passing an object to be treated which has been inputted from an inlet-side casing and for transferring the object to be treated into a cylindrical heating furnace (10) is installed at an end portion of the cylindrical furnace (10) which heat-treats the object to be treated and an external casing (22) covers the screw conveyor (20). The ends of a pair of gas supply tubes (28A, 28B) are coupled proximal to the base end-side portion of the external casing (22), so that the pair of gas supply tubes (28A, 28B) are connected. Heated inert gas is supplied from the pair of gas supply tubes (28A, 28B) to a space (S) defined between the external casing (22) and an internal casing (24).
