Description

Technical Field

[0001] The utility model belongs to the technical field of calcium carbide furnace equipment, and specifically relates to an electrode device for calcium carbide production. Background Art

[0002] A calcium carbide furnace is a device used to produce calcium carbide. It mainly produces calcium carbide by melting the materials in the furnace through the high temperature generated by the electric arc. It is an important equipment in the petrochemical industry. The calcium carbide produced is the main raw material for chemicals such as acetylene. The calcium carbide furnace mainly includes a furnace body, electrodes and a power supply system. The working principle of the calcium carbide furnace mainly includes using electric current to decompose the electrolyte under high temperature conditions under the action of the electrodes in the furnace to generate calcium carbide.

[0003] At present, most of the ways to open the lid of calcium carbide furnaces are electric. Once the motor fails or encounters an emergency such as a power outage, the originally automated opening process will be seriously affected, making it extremely difficult to open the furnace lid, or even impossible to open it smoothly. This situation not only brings great inconvenience to daily operations, but also increases the potential risks in the production process, such as delaying production progress, increasing equipment maintenance costs, and even causing production safety accidents due to the failure to open the furnace lid in time. Utility Model Content

[0004] The purpose of this utility model is to provide an electrode device for calcium carbide production, which can ensure that when an abnormality occurs in the electric part, it can quickly switch to manual mode to complete the opening or closing of the cover.
