Embodiment Construction
[0009] Such as figure 1 , figure 2 As shown, the present invention is an aluminum electrolytic cell anode carbon protective ring, which includes a ring body, the ring body is composed of three arc-shaped segments, and the connection interface of the arc-shaped segments is a corrugated type that engages with each other. The arc corresponding to the arc segment is 120°.
[0010] The working process of this example: when using a carbon protection ring, install its three parts on the anode steel claw, and connect the three arc-shaped protection rings with corrugated connection interfaces one by one, stick them together with a little glue, and combine them without binding firm.

The invention provides an anode carbon protecting ring of an aluminum reduction cell, comprising a ring body, wherein the ring body is composed of three arc segments and the connecting interfaces of the arc segments are in the mutually-meshed ripple type. The anode carbon protecting ring provided by the invention has the beneficial effects that the connection is convenient; the generality is good; the matching is tight and sealing is realized via adhesive; the dislocation is difficult; the anode steel claw is effectively protected; and the operating stability of the reduction cell is increased.
Description
technical field [0001] The invention belongs to the field of aluminum electrolytic cells, in particular to an aluminum electrolytic cell anode carbon protection ring structure. Background technique [0002] The anode of the aluminum electrolytic cell is called the heart of the electrolytic cell, which not only means that the anode plays a very important role in the electrolysis process, but also because the anode consumption accounts for about 15% of the primary aluminum production cost. Due to the structural defects of the anode carbon block used in the aluminum electrolytic cell, the anode needs to be replaced regularly. The consumption rate of the prebaked anode carbon block on the aluminum electrolytic cell is about 1.45 cm per day, and the service life is generally 26 days. If used, the liquid electrolyte in the aluminum electrolytic cell will corrode the anode steel claws and pollute the aluminum liquid in the electrolytic cell. Contents of the invention [0003] Th...
