EXHAUST PIPE FOR ROTARY TYPE SINTERING FURNACE

摘要

An exhaust device for a rotary sintering furnace is provided to improve exhaust efficiency in the cylindrical furnace body by mounting double exhaust pipes on an upper central part of a cylindrical furnace body mounted on the rotary sintering furnace, wherein the double exhaust pipes are assembled with each other in such a way that a plurality of vent holes formed in outer peripheral surfaces of the double exhaust pipes intersect with each other. In a rotary sintering furnace comprising: a furnace body of which an upper part is covered with a disc type cover, and in which an insulating material embedded; a rotary support including a setter having a plurality of ceramic formed bodies vertically stacked on an upper part thereof; and a liftable and lowerable means vertically transferring the rotary support in a supporting frame, an exhaust device for the rotary sintering furnace comprises an exhaust pipe(200) which is penetratingly connected to a central part of the disc type cover and includes a first exhaust pipe(210) and a second exhaust pipe(220) having a plurality of through holes(211,221) formed in outer peripheral surfaces thereof, the second exhaust pipe being inserted into the first exhaust pipe such that the plurality of through holes are overlapped with each other. The first exhaust pipe has reciprocally symmetrical locking ports(213) and locking moving ports(214) formed in an upper outlet(212). The second exhaust pipe locking projections formed at positions adjacent to an upper outlet(222) on an outer peripheral surface thereof such that the locking projections are inserted into the locking moving ports through the locking ports.
