Description
Technical Field
The invention relates to a device for reducing growth of a shell head packet, in particular to a device for reducing growth of an aluminum electrolysis shell head packet.
Background
The aluminum electrolysis crust breaking system consists of a crust breaking cylinder and a crust breaking hammer head. The crust breaking hammer head is a cylindrical structure which is made of Q235 cast iron and has a hollow upper part and a solid bottom, the hollow part and the solid part are welded into a whole, and are fixed at the bottom of the cylinder by a snap ring and move in a reciprocating manner under the pushing of the cylinder.
And part of the liquid electrolyte can be adhered to the ramming hammer after each ramming. Because the liquid electrolyte has high viscosity and is easy to solidify after being cooled in air. In normal production, each electrolytic cell is provided with 6 groups of crust breaking mechanisms, and each group of crust breaking mechanisms crust every 60s on average. After several times of crust breaking, the crust breaking hammer head can be stuck with thick electrolyte to form a crust head bag. When the solid electrolyte completely wraps the shell head, and the blanking crust breaking system cannot normally crust, the cell control machine can send out an alarm signal. At this time, the electrolyzer needs to use hammers (each 5 kg) to forcefully knock the head of the shell to knock and break the solid electrolyte and then drop the solid electrolyte, and each electrolyzer consumes one hammer per shift (8 hours per shift), thereby greatly increasing the labor intensity of the electrolyzer. Meanwhile, the crust breaking hammer head is damaged and is frequently knocked.
Therefore, there is a particular need for an apparatus for reducing the growth of head packets of aluminum electrolysis cells to solve the above-mentioned problems.
