The specific actions are as follows:
the control cabinet 10 is placed on one side of the electrolytic bath body 1. When the crust breaking and blanking system works, the control cabinet 10 firstly sends out a crust breaking operation instruction. By feeding power to the electric crust breaker 3 via the cable 8, the electric crust breaker 3 starts to move downwards. The sensor transmits an electrical signal to the control cabinet 10 via the cable 8 when the sensor moves below the electric crust breaker 3. The control cabinet 10 sends out the ascending instruction of the electric crust breaker again, and the electric crust breaker 3 starts to ascend. When the electric crust breaker 3 moves to the upper limit, the sensor also obtains a signal to enable the control cabinet 10 to send a command of stopping rising. Thereby completely completing one crust breaking operation.
When the electric feeder 4 obtains a feeding instruction of the control cabinet 10, the electric feeder rotates 180 degrees and transmits position information to the control cabinet 10 through a sensor. At this time, the control cabinet 10 sends out a rotation stop instruction, and after 6 seconds, the electric feeder finishes feeding alumina in the charging barrel. The control cabinet 10 sends a rotation command to the electric feeder 4. The electric blanking device 40 is rotated by 180 degrees again to obtain the stop instruction when the sensor position information is obtained. Thus, complete blanking operation is completed.
The cable 8 is used for transmitting crust breaking and blanking instructions to the electric crust breaker 3 and the electric blanking device 4 to realize the movement of the electric crust breaker and the electric blanking device. And the sensor signals on the electric crust breaker 3 and the electric feeder 4 are transmitted to the control cabinet 10, and the control module 102 on the control cabinet 10 controls the electric crust breaker 3 and the electric feeder 4 in real time.

The PLC controller 103 in the control cabinet 10 gives a fueling instruction to the fueling instrument 105, and the fueling instrument 105 starts supplying the oil to the oil drip pipe 9. The oil drip line 9 feeds the lubricating oil to the distributor 7, which distributor 7 distributes it to the quick service pipe 75 through the main oil line 74. Finally, quick-insertion tube 75 delivers the lubricating oil to electric crust breaker 3. The electric crust breaker 3 is lubricated.

Specific electrical control principles, as shown in 16 to 18:
before the isoelectronic crust breaker acts, the upper limit sensor is electrified. When the electric crust breaker KM1 acts, the motor rotates forwards, and the electric crust breaker moves downwards. After the lower limit sensor is touched, the PLC controller delays for 1 second to start the motor reversing contactor KM 2. The electric crust breaker is moved upwards, and the motor stops rotating after the electric crust breaker moves to the upper limit sensor. Waiting for the next action. And the PLC controller operates the 2# crust breaker after obtaining the crust breaking input signal again. The 1# crust breaker and the 2# crust breaker are operated at intervals in sequence.
When the electric blanking device acts, the left limit switch is in a conducting state, and when the PLC controller obtains a blanking signal, the PLC sends a signal to the 1# blanking device contactor KM 5. The contactor KM5 attracts the 1# blanking device motor to rotate, and when the 1# blanking device motor rotates to the right limit switch, the PLC obtains a signal to cut off the 1# blanking device contactor KM 5. After 3 seconds of delay, the signal is sent to a No. 1 blanking device contactor KM 5. At this time, the No. 1 blanking device motor starts to rotate again, and the motor rotates to the left limit switch. And stopping the rotation of the No. 1 blanking machine motor. And when the PLC controller obtains the blanking signal again, starting to operate the 2# blanking device motor. The action is the same as that of the No. 1 blanking device. And sequentially operating 1# blanking device and 2# blanking device at intervals.
The PLC automatically added oil every three hours, with an electrical signal to KM7 for 5 seconds. As shown in fig. 19, the oil pump lubricates the 1# and 2# crust breakers by distributing the lubricating oil evenly into 2 portions by the distributor.
