Problems solved by technology
[0002] At present, the alumina used in the industrial aluminum electrolysis is transported through the air-cushion belt conveyor system, and the air-cushion belt conveyor system has more equipment, more complicated processes, and a high degree of automation, which requires specially designed Control system, therefore, higher cost and energy consumption
In addition, when there is an abnormality in the conveying system, it cannot be found in time, and it is easy to cause material leakage in the silo, blockage of the outlet, etc., resulting in waste of raw materials and damage to equipment, etc.

The invention provides a control method of an air cushion belt conveyor system of alumina for aluminum electrolysis. The control method comprises the following steps of: carrying out a joint starting / stopping control step; controlling the air cushion belt conveyor system according to the preset joint starting / stopping mode to convey alumina from a raw material warehouse to a midbin; in the joint starting / stopping control step, detecting whether the air cushion belt conveyor system is abnormal in real time or not, if so, converting the joint starting / stopping control step to a subarea starting / stopping step; carrying out the subarea starting / stopping step: controlling the air cushion belt conveyor system to run according to the preset subarea starting / stopping mode. The embodiment of the invention can realize the joint control and subarea control of the air cushion belt conveyor system, and the control method has the advantages of strong alumina transmission capacity, no damage to alumina and low energy consumption; in addition, when the system is in an abnormal state, an alarm is given to remind personnel of timely processing, so the control method has higher security.
Description
technical field [0001] The invention relates to the technical field of aluminum electrolysis, in particular to a control method of an air-cushion belt conveyor system for aluminum oxide used in aluminum electrolysis. Background technique [0002] At present, the alumina used in the industrial aluminum electrolysis is transported through the air-cushion belt conveyor system, and the air-cushion belt conveyor system has more equipment, more complicated processes, and a high degree of automation, which requires specially designed The control system, therefore, has a higher cost and energy consumption. In addition, when there is an abnormality in the conveying system, if it cannot be found in time, it is easy to cause material leakage in the silo, blockage of the outlet, etc., resulting in waste of raw materials and equipment damage. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004] For thi...
