Automatic pressure-disengaging machine for aluminum electrolysis anode scrap carbon block and carbon block pressure-disengaging method

Abstract

The invention relates to an automatic pressure-disengaging machine for an aluminum electrolysis anode scrap carbon block and a carbon block pressure-disengaging method. The pressure-disengaging machine comprises a rack (1), a front stand column (11), a rear stand column (2), two steel claw hanging frames (3), a pressure-disengaging knife (5), and two pressure-disengaging oil cylinder supporting plates (14), wherein the front stand column (11) and the rear stand column (2) are symmetrically arranged on the two sides of the rack, the two steel claw hanging frames (3) are symmetrically installedon the inner side of the front stand column and extend forwards, the pressure-disengaging knife (5) is arranged between the two steel claw hanging frames and can move front and back and up and down, the two pressure-disengaging oil cylinder supporting plates (14) are symmetrically installed on the inner sides of the two steel claw hanging frames and extend upwards; and a pressure-disengaging oil cylinder (6), a guide rod fixing device (12), two pressure-disengaging knife positioning oil cylinder supporting plates (7) and a pressure-disengaging knife positioning oil cylinder (4), wherein the pressure-disengaging oil cylinder (6) is installed between the two pressure-disengaging oil cylinder supporting plates, the guide rod fixing device (12) is welded to the front ends of the two pressure-disengaging oil cylinder supporting plates, the two pressure-disengaging knife positioning oil cylinder supporting plates (7) are symmetrically installed on the inner side of the rear stand column, andthe pressure-disengaging knife positioning oil cylinder (4) is installed between the two pressure-disengaging knife positioning oil cylinder supporting plates. The pressure-disengaging machine is simple in structure, low in manufacturing cost and safe and reliable to use. The method for pressure-disengaging the anode scrap carbon block is simple, efficient and good in pressure-disengaging effect.

Description

technical field [0001] The invention belongs to the technical field of anode residue treatment devices for aluminum electrolysis guide rods, and in particular relates to equipment for automatically pressing off anode residue carbon blocks on aluminum electrolysis guide rods. Background technique [0002] Anodes in aluminum electrolytic production include aluminum guide rods, steel claws and carbon blocks. After the anode has been used for a period of time, most of the carbon block is consumed, and the anode carbon block needs to be removed from the steel claw, and then reassembled into a new anode. At present, most aluminum electrolysis plants use manual beating to remove the anode carbon block, which has problems such as high labor intensity, low work efficiency, serious pollution of the working environment, and great safety hazards.
