Description

Technical Field

[0001] The utility model belongs to the technical field of sling equipment, and in particular relates to a special insulating sling for a plate lifting machine for short-circuit treatment of a copper electrolytic production tank surface. Background Art

[0002] During the copper electrolysis production process, it is necessary to deal with the short-circuit plate granulation that occurs during the electrolysis production. After production practice, the cathode plate weighs 45-200Kg. When the cathode plate is lifted by the short-circuit plate lifting machine hook to deal with the granulation, the hook head is connected to the direct current in the electrolysis through the cathode plate in the electrolytic cell. In order to avoid the direct current of the electrolysis being introduced into the electrical AC circuit such as the plate lifting machine, affecting the normal use of various electrical components, the lifting device must ensure reliable insulation performance and lifting strength.

[0003] The short-circuit plate granulation is handled manually. Because the cathode plate itself is too heavy to be lifted manually, the operator uses a scoop to detect the granulation location in the electrolyte and uses a long stainless steel flat shovel to remove the granulation on the plate surface. Because the underwater treatment is invisible, difficult and incomplete, it is easy to cause the anode mud at the bottom of the electrolyte tank to float, further causing large-scale granulation, affecting the quality of the cathode copper, and requiring high skills from the operator.
