Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrodes, in particular to a thread sealing device for the end of a graphite electrode. Background Art

[0002] Graphite electrodes are widely used in electric furnace smelting. Impregnation of graphite electrodes can reduce the porosity of the product, increase the density and compressive strength, and reduce the resistivity of the graphite electrodes. It is a process to change the physical and chemical properties of graphite electrodes. However, the threads at both ends of the graphite electrode are prone to deformation during impregnation, causing damage to the electrode.

[0003] Publication (Announcement) No.: CN210240273U discloses a graphite electrode end thread sealing device, including a conveying trolley, a sealing front end cover, a sealing rear end cover and a connecting screw. After the graphite electrode is transported to the graphite electrode conveying trolley by a lifting device, the sealing front end cover and the sealing rear end cover are manually installed on the screw. The second stop block in the connecting screw is fixed by the first stop block in the sealing rear end cover, so that the screw does not rotate with the rotation of the nut. The nut is tightened so that the front end cover base and the rear end cover base are close to the mounting surface.

[0004] In the prior art, the threaded section at the end of the graphite electrode is currently only wrapped and protected by a threaded sealing sleeve 2, but the protective sealing effect of the threaded section at the end of the graphite electrode is not good, and dust and other particles are easily introduced into the thread, which affects the conductive effect during conductive construction and seriously causes resistance damage to the conductive contact head. Therefore, it is necessary to keep the threaded part of the graphite electrode clean and protected. Utility Model Content
