Abstract

The invention relates to an internal rotary vacuum sealing assembly for a high-temperature vacuum sintering furnace. The internal rotary vacuum sealing assembly comprises a fixed part and a movable part, wherein the bottom of the fixed part is connected with a charging bucket, the top of the fixed part is connected with the movable part, a cavity which is used for containing the movable part is formed in the fixed part, an air inlet channel which communicates with the outside is formed in the bottom of the cavity, so that the cavity communicates with the interior of the charging bucket, a vacuum interface is formed in the side wall of the fixed part, so that the fixed part communicates with the cavity, the lower part of the movable part is arranged in the cavity, the upper part of the movable part penetrates through the top of the fixed part, and the upper part of the movable part is movably connected with the top of the fixed part, so that the movable part moves up and down relative to the fixed part. According to the internal rotary vacuum sealing assembly, the movable part and the fixed part are connected and disconnected so as to close and open the vacuum channel, and the vacuum channel is sealed by adopting surface-to-surface contact, so that the operation is flexible and convenient, the sealing effect is good, the condition of air leakage does not exist, and the internalrotary vacuum sealing assembly is suitable for repeated operation.

Description

technical field [0001] The invention relates to the technical field of heating equipment in a high-temperature vacuum sintering furnace, in particular to an inner-rotating vacuum-pumping sealing assembly and a vacuum-pumping material tank for a high-temperature vacuum sintering furnace. Background technique [0002] When the high-temperature vacuum sintering furnace sinters materials, it is necessary to use a pan or a tank as a container for the material, and then put it into the sintering furnace together with the pan or tank for sintering. The temperature in the sintering furnace reaches 1000°C- 1800°C, in a high-temperature atmosphere, the tank not only needs to ensure its own tightness, but also ensures that the vacuum inside the tank meets the process requirements, which requires vacuuming the inside of the tank, usually on the top cover of the tank A vacuum tube connected to the inside of the material tank is provided, and the vacuum is pumped through the vacuum tube. ...
