Multi-stage drying device for producing silicon carbide sealing rings

Abstract

The invention discloses a multi-stage drying device for producing silicon carbide sealing rings, and relates to a drying device, in particular to a multi-stage drying device for silicon carbide sealing rings, which comprises an operating table, a first support frame is fixedly arranged at the top of the operating table, a first drying structure is fixedly arranged on one side of the first supportframe, a second drying structure is arranged on one side of the first drying structure, a heat conduction structure is fixedly installed at the bottom of the second drying structure, a third drying structure is arranged on one side of the second drying structure, the third drying structure is fixedly installed on the operating table, and another heat conduction structure is arranged at the bottomof the third drying structure. Preliminary comprehensive drying is conducted through the first drying structure, the exteriors of the sealing rings are dried through the second drying structure and the heat conduction structure, the interiors of the sealing rings are dried through the third drying structure and the heat conduction structure, and the drying effects of the sealing rings is improvedthrough three times of drying.

Description

technical field [0001] The invention relates to a drying device, in particular to a multi-stage drying device for producing silicon carbide sealing rings. Background technique [0002] Silicon carbide (SiC) is made of quartz sand, petroleum coke (or coal coke), wood chips (salt needs to be added when producing green silicon carbide) and other raw materials through resistance furnace high temperature smelting, and the sealing ring is a ring with a gap. The seal is placed in the ring groove of the sleeve, the sleeve and the shaft rotate together, and the seal ring is pressed against the inner hole wall of the stationary part by the elasticity of the gap after being pressed together, and the seal can be achieved. role. [0003] The sealing ring made of silicon carbide is the silicon carbide sealing ring. After making the silicon carbide sealing ring, it needs to be dried and stored, but the existing technology is only simple drying, which cannot guarantee the sealing of silico...
