A continuous graphite purification equipment and its insulating dynamic sealing device

Abstract

The present application discloses a continuous graphite purification equipment and its insulating dynamic sealing device. The insulating dynamic sealing device includes: a high-temperature heat-resistant and heat-insulating transmission rod coaxially connected between the geared motor and the graphite feeding screw, and the The high-temperature-resistant and heat-insulating transmission rod passes through the furnace shell and the insulation layer; a water-cooled jacket seat is arranged between the high-temperature-resistant and heat-insulated transmission rod and the furnace shell. The above-mentioned continuous graphite purification equipment and its insulating dynamic sealing device provided by the application include a high-temperature heat-resistant and heat-insulating transmission rod coaxially connected between the geared motor and the graphite feeding screw, thereby avoiding the heat transfer of the graphite feeding screw. The problem caused by the reduction of the sealing performance, and the water-cooled jacket seat is arranged between the high-temperature-resistant heat-insulating transmission rod and the furnace shell, which can cool the transmission rod in real time and ensure the sealing performance of the continuous graphite purification equipment and security.

Description

technical field [0001] The invention relates to the field of high-temperature equipment, in particular to a continuous graphite purification equipment and an insulating dynamic sealing device thereof. Background technique [0002] Graphite has excellent properties such as high and low temperature resistance, corrosion resistance, radiation resistance, electrical conductivity, thermal conductivity and self-lubrication. It is widely used in various fields of science and technology engineering, especially in nuclear energy, aviation, aerospace, wind energy, electronics and military fields. Indispensable strategic material. When the carbon content of natural graphite is 85-90%, it is called medium-carbon graphite. It is high carbon graphite or high purity graphite. At present, domestic graphite ore production and processing enterprises mainly use Acheson furnace to purify natural graphite, which belongs to intermittent production, which has high energy consumption and high cos...

Problems solved by technology

During the graphite purification process, the temperature inside the graphite heating cylinder is as high as 2000°C, and a small amount of process gas is required. If the sealing of the equipment cannot be guaranteed, the heat and process gas will diffuse or leak outward, which will damage the equipment and staff. safety impact
