Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of calcium carbide furnace discharge machine equipment, in particular to a cooling device for a calcium carbide production discharge machine. Background technology:
[0002] The calcium carbide furnace tapping machine mainly plays the functions of opening and pulling eyes. The furnace eye is opened to release the calcium carbide liquid that has been smelted by high-temperature electrochemical smelting; the eye is pulled because the calcium carbide liquid is affected by sticky slag during the outflow process, which causes the flow rate to slow down, affecting the tapping time. During the eye pulling operation, the tapping rod of the tapping machine is extended to perform reciprocating poking and pulling to clear the furnace eye and the furnace body flow channel. After the eye pulling operation is completed, the tapping rod of the tapping machine retracts. Since the temperature of the calcium carbide furnace is as high as 1800 degrees Celsius, the temperature of the tapping rod is extremely high after the operation technology, so the tapping rod needs to be sprayed for cooling. In the prior art, multiple cooling water nozzles are usually arranged above the tapping rod. The cooling water is sprayed on the tapping rod to generate a large amount of steam, and the cooling water splashes everywhere. At the same time, the oxide scale on the tapping rod will also be scattered everywhere. The disorderly discharge of steam, the splashing of cooling water and the disorderly scattering of oxide scale on the tapping rod seriously pollute the workshop environment and easily cause failure of the transmission system of the tapping machine.
