The cathode system is one of the core parts of the whole device as a discharge electrode, which directly affects the operation and efficiency of the dust collector. The rapping and dust cleaning effect of the anode and cathode of the electric dust collector directly affects the dust removal efficiency of the electric dust collector, therefore, in order to remove the dust on the electrode plate and electrode wire, appropriate rapping force is needed, and periodic rapping is carried out, so that the electrode plate and electrode wire can obtain the acceleration required for dust cleaning, so that the dust collection or discharge of the electrode plate and electrode wire is continuously updated and efficient, and the dust adhered to the electrode plate and electrode wire falls into the dust hopper and is discharged in time through rapping.
