置。[Scope of Claim for Utility Model Registration] (1) In a sintering furnace in which a compartment containing a case is formed with a heat insulating material in a tank and a heating element is installed to heat the case from the outer periphery, gas is introduced to one side. Connect the lower part of the case with the opening and the trap inside the lower tank provided outside the tank with an exhaust pipe,
A debinding device for a sintering furnace, characterized in that a heating means for heating the binder to an extent that the binder does not solidify is provided on the outer periphery of the exhaust pipe, and a shutoff valve is provided at the lower end of the exhaust pipe. (2) The debinding device for a sintering furnace according to claim 1, wherein the valve body and valve seat of the shutoff valve are made of heat-resistant material such as heat-resistant steel or ceramics. (3) The shutoff valve has a disc-shaped valve body with an upper and lower structure fixed by a hollow rod, and the disc-shaped valve disc is loosely fitted into a substantially cylindrical valve seat, and the valve body is inserted into the hollow of the rod. Utility model registration claim 1 that allows inert gas to be introduced into the valve seat through the small hole between the two discs
2. A debinding device for a sintering furnace according to item 2.
