Description

Technical Field

[0001] The utility model belongs to the field of hydrometallurgical equipment, and in particular relates to a nickel electrolytic conductive rod crystal removal device. Background Art

[0002] During nickel electrolysis using soluble anode diaphragm electrolysis, the starting electrode and high-sulfur anode plates are connected to the busbars at the sides of the electrolytic cell via anode and cathode conductive rods, forming a DC electrolysis system. During the electrolysis process, nickel sulfate crystals form inside and outside the anode and cathode conductive rods, and the copper rods corrode. This can cause poor conductivity or short circuits at the contact points, increasing the cell voltage, increasing electricity consumption per ton of nickel, and even halting production. Therefore, cleaning the conductive rods is crucial. Traditional cleaning methods include manual sanding with sandpaper, laser cleaning, and ultrasonic cleaning, which are labor-intensive, inefficient, incomplete, complex, and require a large floor space.

[0005] A nickel electrolytic conductive rod crystal removal device comprises a bracket fixed to the ground, a horizontal roller is connected to the bracket, and one end of the roller is connected to a driving assembly, and the driving assembly is used to drive the roller to rotate;

[0006] The drum has a hexagonal hollow structure. The drum shell consists of two layers. The outer shell is made of cast steel and the inner shell is made of wear-resistant and corrosion-resistant material. The outer shell and the inner shell are fixed together by bolts. The two ends of the drum are tapered. A material inlet is provided in the middle of the drum, and a drum cover is connected to the material inlet. Conductive rods are placed into the drum through the material inlet.

[0007] Furthermore, a plurality of crowbar sleeves are welded and fixed to the outer surfaces of the tapered portions at both ends of the drum, and the crowbar sleeves are used to connect crowbars to pry the drum to rotate.

[0008] Furthermore, the cylinder cover is connected to a cover shaft, a cover opening handle and a cover latch.

[0009] The beneficial effects of the present invention are as follows: when a conductive rod is placed in the cleaning device of the present invention, crystallization and corrosion components on the surface of the conductive rod can be removed by rotary cleaning; more conductive rods can be placed in the cleaning device at a time, which helps to improve cleaning efficiency and speed.

[0016] The cathode and anode conductive rods produced during the nickel electrolysis process are made of copper tubes. The cathode rod has a diameter of 32 mm and the anode rod has a diameter of 45 mm. They are first scalded in boiling water for 15-30 minutes to wash away the nickel sulfate crystals on the surface. Then, they are lifted into bundles using an electric hoist and the anode rods are loaded into the inner cavity of the drum 4 through the opened drum cover 16. Rice bran and a small amount of water are added above the copper rods. The drum cover 16 is closed, the lid latch 10 is inserted, and the crowbar 12 is removed.
