Abstract

The invention relates to an outward turning vacuumizing seal assembly for a high-temperature vacuum sintering furnace. The outward turning vacuumizing seal assembly comprises a fixed part and a movable part, wherein the bottom of the fixed part is connected to the charging bucket, the top of the fixed part is movably connected to the movable part, a cavity for accommodating the movable part is formed in the fixed part, an air inlet channel communicating to the outer side is formed in the bottom of the cavity to communicate to the inner side of the charging bucket, a vacuumizing joint is arranged on the side wall of the fixed part to communicate to the cavity, and the lower part of the movable part is arranged in the cavity and the upper part of the movable part is movably connected to thefixed part, so that the movable part displaces up and down relative to the fixed part. The vacuumizing channel is closed and connected by combining and separating the movable part and the fixed part.The vacuum channel is sealed by surface-to-surface contact. The outward turning vacuumizing seal assembly not only is sensitive and convenient to operate, but also is good in sealing effect. An air leakage condition is avoided, and the outward turning vacuumizing seal assembly is more suitable for repeated operations.

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 externally 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 t...
