Abstract

The invention relates to an automatic air blowing and cooling device for bottom of an aluminum electrolytic cell. The automatic air blowing and cooling device is arranged at the lower end of the electrolytic cell; a thermal imager of the automatic air blowing and cooling device can automatically measure the temperature of the cell bottom; a controller judges a high-temperature part, needing to becooled, of the cell bottom according to a temperature field, and then controls a transverse axis moving frame and a longitudinal axis moving frame to move so that an air blower can be dragged to a position below the high-temperature part of the cell bottom; and the air blower is started to perform air blowing and cooling, and is stopped in time after cooling is completed.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolysis, and in particular relates to an automatic blowing and cooling device for the bottom of an aluminum electrolytic cell. Background technique [0002] The bottom of the aluminum electrolytic cell is usually composed of a refractory insulation lining and a steel shell. During the aluminum electrolytic production process, the internal temperature of the aluminum electrolytic cell can reach 950°C or above. When the carbon material at the bottom of the cell is damaged, the refractory and thermal insulation lining becomes uneven, and the aluminum liquid or electrolyte may flow down to the bottom of the cell, burning The furnace leaks due to the penetration of the tank shell steel plate, destroys the aluminum electrolytic cell, and is forced to stop the cell. In severe cases, the busbar will be blown, causing production accidents. Therefore, in production, it is necessary to monitor the tem...
