Description

Technical Field

[0001] The present application relates to the technical field of baking furnaces, and in particular to a graphite electrode baking furnace. Background Art

[0002] Graphite electrode is a high temperature resistant graphite conductive material made by raw material calcination, crushing and grinding, roasting, impregnation, graphitization and mechanical processing. The roasting of graphite electrode is the process of further processing the electrode after the initial calcination, the purpose is to further improve the physical and chemical properties of the electrode. Since the secondary roasted graphite electrode is usually a formed cylinder, it is usually necessary to use a roasting furnace to process the formed cylinder.

[0003] At present, a general roasting furnace places a carrier plate in the roasting furnace, places a graphite electrode on the carrier plate, heats the carrier plate, and heats and roasts the graphite electrode through heat conduction, thereby improving the crystallinity of the graphite electrode and further improving the conductivity effect.

[0004] However, during the roasting process, since the graphite electrode is always in a static state, the graphite electrode can only be heated on one side, resulting in uneven heating of the graphite electrode, thereby reducing the production quality of the graphite electrode. Summary of the invention

[0011] By adopting the above technical solution, the igniter heats and bakes the electrode body, the temperature inside the furnace body increases, and the water tank is heated. The water in the water tank is heated to form water vapor, and the water vapor flows along the connecting pipe to the impeller position. The water vapor drives the impeller to rotate, and the impeller transmits power to the driven part, so that the driven part can easily drive the electrode body to rotate. Through the transfer of heat energy, the number of driving sources is reduced, thereby reducing costs and improving production efficiency.

[0012] Optionally, the driven part includes a connecting rod, a sliding rod and a spur rack, the connecting rod is rotatably connected to the end face of the impeller, the sliding rod is slidably penetrated on the furnace body, and the sliding direction is a vertical direction, one end of the sliding rod is rotatably connected to the end of the connecting rod away from the impeller, and the other end is fixedly connected to the spur rack, and the axial direction of the spur rack is the same as the axial direction of the sliding rod; the spur rack is meshed with a gear sleeve, the gear sleeve is rotatably connected to the threaded rod and is sleeved on the threaded rod, and the gear sleeve is fixedly connected to the second chuck.

[0015] By adopting the above technical solution, the water in the water tank is heated to form water vapor, and the water vapor enters the cooling hood along the connecting pipe. The water vapor in the cooling hood continues to accumulate, and the water vapor flows in the cooling pipe. Since the outside temperature is much lower than the temperature inside the furnace, the water vapor begins to condense, and the impeller transmits power to the transmission part, and the transmission part drives the cooling part to cool the cooling pipe, thereby increasing the condensation speed of the water vapor and further improving the utilization rate of water.

[0016] Optionally, the transmission part includes a through rod, a synchronous wheel one and a synchronous wheel two, the through rod is coaxially fixedly connected to the impeller and rotatably penetrates the cooling cover; the synchronous wheel is coaxially fixedly connected to an end of the through rod away from the impeller; the synchronous wheel two is rotatably connected to the top end of the cooling cover, and the synchronous wheel one and the synchronous wheel two are jointly sleeved with a synchronous belt.
