Description

Technical Field

[0001] The utility model relates to the technical field related to material processing, in particular to a cooling pool for graphite electrode production. Background Art

[0002] In the production process of graphite electrodes, a series of high-temperature treatment processes, such as roasting and graphitization, are carried out. These processes keep the graphite electrode blank in a high-temperature state. In order to ensure product quality and facilitate subsequent processing, it must be cooled quickly and effectively. The cooling pool is one of the key equipment to achieve this cooling process. Taking the graphite electrodes produced by the graphitization furnace as an example, the temperature is extremely high when they come out of the furnace. If they are cooled naturally, it will not only take a very long time, but also cause the internal structure of the graphite electrode to be uneven due to the slow cooling speed, resulting in internal stress, which in turn affects its physical properties and performance, such as reducing strength and increasing resistivity. Therefore, a cooling pool is particularly needed for the production of graphite electrodes.

[0003] However, during use, existing cooling pools usually only focus on the cooling function, lack effective water filtration and purification measures, and are unable to remove impurities, particles, organic matter, etc. in the water. As time goes by, impurities in the water increase, and dirt and scale are easily formed on the surface of the cooling equipment, reducing the cooling efficiency and affecting the performance and service life of the equipment. Existing cooling pools may not have a special stirring device or the stirring effect is poor, resulting in uneven water temperature in the cooling pool, affecting the cooling effect of cooled objects such as graphite electrodes, causing local overheating or overcooling, and thus affecting product quality and the heat dissipation efficiency of the graphite electrodes.
