[0002] my country is a major producer of electrolytic aluminum. During the aluminum electrolysis production process, high-temperature electrolytes penetrate and corrode the lining materials, causing deformation and rupture of the lining structure of the electrolytic cell. The aluminum liquid and electrolyte in the electrolytic cell leak out from the cracks. Generally, the electrolytic cell needs to be shut down for overhaul after 5 to 6 years of use. All the waste lining materials taken out are referred to as overhaul slag, which includes waste electrolytic aluminum cathodes and is a hazardous solid waste.

[0003] The common method of processing waste cathodes of electrolytic aluminum is to grind them into powder after crushing. After the crusher crushes the waste cathodes of electrolytic aluminum, it needs to enter the next process for grinding. However, when the crushed waste cathodes of electrolytic aluminum are placed in the next machine, a large amount of dust will be generated. The dust will float everywhere and be inhaled into the lungs of workers, which will make workers prone to lung occupational diseases. In addition, some solids in the dust of the waste cathodes of electrolytic aluminum after grinding have not been completely ground, which are easy to accumulate on the filter net and affect the screening efficiency. Utility Model Content

A crushing device for waste cathode of electrolytic aluminum is proposed.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the utility model is in use, a large amount of dust generated by crushing the electrolytic aluminum waste cathode and placing it in the next machine can be absorbed into the air inlet pipe through the fan in the dust suction structure, and finally concentrated into the dust collecting box.
