[0026] Working principle: Insulating gaskets are important insulating materials in the fields of electricity and electronics. One of their core functions is to provide efficient electrical insulation. Insulating gaskets in spiral jacks are usually made of insulating materials, which can effectively isolate conductors with different potentials to ensure electrical safety. Insulating gaskets are used at the pipe connections and mechanical seals of spiral jacks to ensure the sealing of the system. The insulating gaskets of spiral jacks currently used in aluminum electrolysis will be damaged due to the long angle of the anode and poor insulation. When replacing, you need to use a jack to support the anode busbar and remove the cylindrical pin to replace the insulation. Gaskets, such operation has great safety hazards. Once the large busbar falls, it will affect a series of safety. For this reason, a 3mm thick insulating plate is used to make a U-shaped insulating gasket. The inner diameter of the U-shaped insulating gasket is the same as the outer diameter of the cylindrical pin, and the outer diameter of the U-shaped insulating gasket is the same as the outer diameter of the original insulating gasket. When replacing the insulating gasket, there is no need to remove the cylindrical pin. First, the original damaged insulating gasket is removed by destruction, and then the two U-shaped insulating gaskets are directly inserted. That is, the first U-shaped insulating gasket 1 and the second U-shaped insulating gasket 2 are respectively set on the outer surface of the cylindrical pin, and the two are The outside can be cut apart from each other, and a cutting tool can be used to cut the insulating gasket. The silicone pad 6 is made of silicone and is relatively soft, which reduces the extrusion force between the gasket and the mounting surface. The wear-resistant pad 8 is made of high manganese steel and has good wear resistance. The anti-slip pattern 9 can increase the friction between the mounting surface and the gasket, making it more secure. The circular hole 3 can effectively disperse the tightening pressure to prevent damage and deformation of the gasket due to excessive local pressure, thereby extending the service life of the insulating gasket. The filling layer 11 is filled with nitrile rubber and has good heat resistance and air tightness. The flame retardant layer 12 is made of antimony trioxide, which can improve the insulation performance. The flame retardant performance of the edge gasket, the anti-compression strip 4 and the anti-compression ring 5 are made of aluminum alloy material with high hardness, and are evenly spaced and distributed on the outer rings of the first U-shaped insulating gasket 1 and the second U-shaped insulating gasket 2, which can effectively resist external forces, improve the external force resistance of the first U-shaped insulating gasket 1 and the second U-shaped insulating gasket 2, and extend the service life of the first U-shaped insulating gasket 1 and the second U-shaped insulating gasket 2. The waterproof layer 13 is made of asphalt waterproof material and has good waterproof performance. The two sponge pads 10 are directly in contact with the outer surface of the cylindrical pin, reducing the extrusion force on the outer surface of the cylindrical pin.
