The invention discloses a continuous and even graphite electrode cooling device in the technical field of cooling equipment. The continuous and even graphite electrode cooling device is used for solving the technical problem that an existing cooling technology easily causes uneven electrode green body stress relieving. The device comprises a conveying system used for conveying an electrode green body and a spraying system arranged above the conveying system and used for spraying cooling media to the electrode green body, the conveying system comprises a plurality of rotary transmission units distributed in parallel so as to drive the electrode green body to rotate and advance, and the spraying system comprises a cooling medium pipe and a plurality of spraying nozzles arranged on the cooling medium pipe so as to spray the cooling media to the electrode green body. By means of the device, the problems that due to uneven cooling water temperature, the quality of the electrode green body is not stable, and crack defects are prone to being generated in the later period are solved; and by means of the device, the cooling time of the electrode green body can be effectively shortened, thecooling time is controlled to be within 0.5 h-1 h through a continuous and even cooling manner, the production continuity is guaranteed, and the production efficiency is improved.
