[0002] The calcium carbide tapping machine mainly plays the role of opening and pulling eyes. It is an important equipment on the calcium carbide furnace. The tapping machine connects the baking furnace and the rear equipment, and plays a good cooling and transition role. 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 slows down the flow rate and affects the tapping time. During the eye pulling operation, the drill rod of the tapping machine is extended to poke and pull the furnace eye and the furnace body flow channel back and forth to clear the hole. After the eye pulling operation is completed, the drill rod of the tapping machine retracts. Since the temperature of the calcium carbide furnace is as high as 1800 degrees Celsius, a lot of oxide scale and residual calcium carbide oxide scale will appear on the drill rod during the actual production process. The cooled oxide scale and calcium carbide scale are scattered irregularly and uncontrolled to various positions of the tapping machine, which may easily cause failure of the tapping machine transmission system and seriously affect the workshop environment. The oxide scale that is not shed in time may easily cause wear of the guide wheel of the tapping machine. When the furnace eye is poked again, the oxide scale may easily fall off and remain in the calcium carbide furnace, affecting the quality of the calcium carbide product. Utility model content:
