Abstract

The invention provides an internal rotation locking vacuum-pumping tank for a high-temperature vacuum sintering furnace. An internal rotation locking vacuum-pumping sealing component comprises a fixedpart and a movable part, and the bottom of the fixed part is used for connecting with the tank; the top of the fixed part is used for connecting with the movable part, and the fixed part is internally provided with a cavity for holding the movable part; the bottom of the cavity is provided with an air inlet channel communicating with outside, and the lower part of the movable part is arranged inthe cavity; the upper part of the movable part penetrates out of the top of the fixed part, and is movably connected to the top of the fixed part; and a wedged connector comprises a connecting pin, alower rotating block and an upper locking block. According to the internal rotation locking vacuum-pumping tank, the closing and opening of a vacuum-pumping channel are achieved through the combination and separation between the movable part and the fixed part, and a vacuum channel is sealed through surface-to-surface contact; not only is the operation flexible and convenient, but also the sealingeffect is very good; and the gas leakage situation does not occur, and the internal rotation locking vacuum-pumping tank is more 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 locking 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. [0003] However, in this str...
