Aluminum electrolysis cell lining waste cathode carbon block crushing device

Abstract

The invention discloses an aluminum electrolysis cell lining waste cathode carbon block crushing device, and belongs to the technical field of aluminum electrolysis waste cathode carbon block crushing treatment devices. The device comprises a support frame, wherein a crushing assembly is arranged at the inner bottom of the support frame, a hopper is fixedly arranged at the upper portion of the crushing assembly, the hopper is connected with a feeding device, the side edge of the bottom of the crushing assembly corresponds to a position of a discharging port, the discharging port is fixedly formed in the side edge of the bottom of the support frame, the crushing assembly comprises an upper crushing assembly body and a lower crushing assembly body, and the lower crushing assembly body is connected with a motor. The device has the beneficial effects that waste cathode carbon blocks are crushed through staggered rotation of the upper crushing assembly and the lower crushing assembly, the uniformity of the crushed waste cathode carbon blocks can be effectively improved, the crushing effect is effectively improved, meanwhile, the lower crushing assembly is controlled by a control box to rotate, the working efficiency can be effectively improved, a structure is simple, and the device is practical and reliable.

Description

technical field [0001] The invention belongs to the technical field of crushing and processing devices for waste cathode carbon blocks of aluminum electrolysis, and in particular relates to a crushing device for waste cathode carbon blocks lining aluminum electrolytic cells. Background technique [0002] In the past two decades, electrolytic aluminum production technology has made great progress. Since my country became the world's largest aluminum producing country in 2001, aluminum production has expanded rapidly in the past decade. In 2017, China's electrolytic aluminum production capacity basically remained at more than 35 million tons. In 2018, the output of electrolytic aluminum reached 36.5 million tons. However, in addition to emitting a large amount of greenhouse gases during its production process, it also emits solid waste that is harmful to the environment-waste tank lining. There is still a certain gap between my country's electrolyzer life and foreign advance...
