Description

Technical Field

[0001] The utility model relates to a carbon black supplement device, in particular to a carbon black supplement device for a vertical continuous furnace, belonging to the technical field of industrial furnaces. Background Art

[0002] During the operation of the continuous furnace, as the temperature inside the furnace continues to rise, the temperature will penetrate and diffuse to the outside. If it is not subjected to certain thermal insulation treatment, it is very easy for the infiltrated heat to pose a threat to the staff and the working environment. The thermal insulation measures currently used in the market include carbon felt, thermal insulation bricks, carbon black, etc. Carbon black is a black particle formed by carbon elements, usually produced by pyrolysis of hydrocarbons (such as natural gas, oil, diesel, etc.).

[0003] The disclosure number is CN220567820U. A carbon black replenishing device for a vertical continuous furnace includes an upper cover, a protective cover and a powder distribution gear. The upper cover includes a motor, a transmission shaft, a transmission pinion, a plurality of support shafts and a plurality of injection ports. The transmission pinion is connected to the output shaft of the motor through a transmission shaft, and a plurality of support shafts are arranged circumferentially along one side of the upper cover close to the transmission pinion. The protective cover is arranged at the bottom of the upper cover. The powder distribution gear is arranged between the transmission pinion and the plurality of support shafts and meshes with the transmission pinion. The bottom of the powder distribution gear is provided with rake teeth, and a plurality of injection ports are fixedly penetrated through the upper cover and pass through the gap between the protective cover and the powder distribution gear.
