Description

Tool for repairing aluminum electrolysis crust breaking cylinder and operation method thereof

Technical Field

The invention relates to the technical field of aluminum electrolysis, in particular to a tool for repairing an aluminum electrolysis crust breaking cylinder and an operation method thereof.

Background

When repairing aluminium electroloysis crust breaking cylinder, disassemble, the installation process accessories are many, process, step are many, because strong magnetism auto-lock magnet can only strike when dismantling the cylinder head, cause equipment to damage, and the process is loaded down with trivial details when overhauing the cylinder moreover, reflects when overhauing the cylinder need around, about, multiple spot position carry out dismouting repair operation, restriction cylinder repair work efficiency's improvement.

The failure mode of cylinder is that the sealing member is ageing, and the gas leakage is serious, and piston rod cylinder damages composition such as serious, changes the parts that become invalid after dismantling all parts during the repair, need place cylinder vertical handstand in the assembling process, and the personnel topple over easily when unstable hard. When the piston rod is assembled, a gap between the piston rod and the cylinder barrel is too small, so that a maintainer can be injured by smashing or clamping; the operation is accomplished by two people, and the cylinder needs to carry out the multiple spot fixed many times, needs another people in time to fix and overhauls the cylinder, and it is consuming a lot to restore crust breaking cylinder. The method specifically comprises the following steps: (1) field disorder: the dismantlement back part is more, occupies the place, and is more chaotic, and the personnel are at the walking in-process, have probably to step on the cylinder part, have the possibility to fall into the injury. (2) Causing equipment damage: when the cylinder head is disassembled or assembled due to the strong-magnetic self-locking, the self-locking device of the cylinder head of the crust breaking cylinder is strong-magnetic self-locking, the cylinder head can be disassembled and assembled only by knocking the cylinder head with a copper bar, the upper cylinder head and the lower cylinder head of the cylinder can be damaged, and the damage rate of the cylinder head is about 7% within 3 months. (3) Potential safety hazards exist in the assembly process: the cylinder needs to be vertically placed upside down in the assembling process, the cylinder is easy to topple over when the force is applied by personnel and is unstable, and the gap between the cylinder and the cylinder barrel is too small during the assembly of the piston rod, so that the overhaul personnel can be injured by smashing or clamping. (4) Waste time and labor: the operation is completed by two persons, the cylinder needs to be fixed for multiple times at multiple points, another person needs to fix the cylinder in time to overhaul the cylinder, and a group counts 30 minutes for repairing one crust breaking cylinder.
