Embodiment Construction

[0017] The determination and timing arrangement of the amount of aluminum fluoride.

[0018] First of all, it is necessary to determine the amount of aluminum fluoride required per day for each electrolyzer. In the production of electrolyzers, a small amount of aluminum fluoride is required every day, and this amount can be calculated according to the following formula: Q 1 =(Q / 365)×0.022Q 1 ——amount of aluminum fluoride required per day, t / day; Q——annual production of primary aluminum, t; According to the shift arrangement of the factory production, the daily delivery time is determined.

[0019] Adding method of aluminum fluoride and configuration of dense phase conveying system.

[0020] Aluminum fluoride is added to the electrolytic cell using a dense phase delivery system. After determining the demand for aluminum fluoride and the timing of adding it, the warehouse and the transfer warehouse can respectively determine the use of one, two, three, five or more sets of d...

Abstract

The invention discloses a material handling device adding aluminium fluoride to electrolytic cell fluoride salt charging box and its method. It includes the following steps: using lifting crown block to hang aluminium fluorides to laying off equipment; unpacking to pressure vessel; using dense-phase transport pipeline to transport aluminium fluoride to transship storehouse and laying off equipment; using its dense-phase transport pipeline to transport the aluminium fluoride to electrolytic cell fluoride salt charging box. The method optimizes the aluminium fluoride adding type, reduces energy consumption, manual operation, and production cost.

Description

technical field [0001] The invention relates to a material conveying method and device for adding aluminum fluoride to an electrolytic cell fluoride salt feed box. Background technique [0002] The current method of adding aluminum fluoride to the electrolytic cell is as follows: figure 1 As shown, first, in the alumina and fluoride salt warehouse 1, the bagged aluminum fluoride 3 is unpacked and loaded into the automobile tanker 5 through the unpacking platform and the unloading device 4 by using the hoisting crane 2 in the warehouse 1, and then using the automobile The tank car 5 blows aluminum fluoride into the feeding bin 6 of the crane, and then transports the aluminum fluoride to the electrolysis workshop 7 through the conveying system of the feeding bin 6 of the crane, and into the fluoride salt bin of the multi-functional crane 8 for electrolysis , and finally aluminum fluoride is added to the fluoride salt feed box 9 on the electrolytic cell of the electrolytic cel...
