Description

Technical Field

[0001] The utility model relates to the technical field of double-circle screws, in particular to a sealed and fixed double-circle screw for an electrolytic cell. Background Art

[0002] The double-turn screw design allows for simultaneous axial movement while rotating. This design not only facilitates installation and removal but also provides the necessary tightening force for sealing. Rotating the screw evenly compresses the sealing material, forming an effective seal. Simultaneously, axial movement further secures the electrolytic cell, preventing movement or leakage during the electrolysis process.

[0003] Existing electrolytic cell sealing and fixing double-circle screws are usually used in situations where the electrolytic cell needs to be sealed and fixed to ensure the smooth progress and safety of the electrolysis process. It involves the rotation and axial movement of the screw, as well as the compression and fixation of the sealing material. Although the above method can realize the connection and fixation of the device to the two ends of the electrolytic cell, when fixing the double-circle screw, the electrolytic cell needs to be equipped with a special tool box to facilitate the use of tools such as wrenches to fix the two ends of the double-circle screw, resulting in a slow installation speed of the double-circle screw. At the same time, when the device is used, the fixing screw is directly inserted into the end plate, and there is a certain gap between the end plate and the fixing screw, which causes the insulating rod to shake slightly.
