The advantages such as regulation is very easy to play an important role in industrial automation, but the energy consumption of crust breaking cylinder accounts for pneumatic system
Total energy consumption significant proportion and capacity usage ratio are the highest.In today that energy problem becomes increasingly conspicuous, crust breaking cylinder energy-conservation to electricity
Solve the energy-saving and cost-reducing of aluminum industry to have great significance.
Current domestic existing crust breaking cylinder air throttle, changes by the pressure of crust breaking cylinder as two-stage output into, and cylinder stretches out crust breaking
Time output high-pressure gas, during retraction export low-pressure gas, though compressed-air actuated usage amount can significantly be reduced, reach joint
Energy purpose, but owing to inputting compressed-air actuated pressure step-down when crust breaking cylinder is retracted, the dynamics causing crust breaking cylinder to be retracted becomes
Little and slow, tup easily bonds more electrolytic aluminium liquid, and cleaning frequency becomes many, and the number of times that gets stuck increases, and have impact on and beats
The technique of shell cylinder crust breaking.
In consideration of it, by installing a kind of novel crust breaking cylinder choking system on electrolysis bath supply branch road, crust breaking cylinder works
Time, choking system output high-pressure gas, complete crust breaking cylinder tup and stretch out crust breaking and be retracted to the whole dynamic of electrolytic aluminium liquid level
Make, do not change the requirement of original crust breaking technique；When crust breaking cylinder tup is back to end from electrolytic aluminium liquid reduction of area and does not works,
Choking system reduces the compressed-air actuated supply pressure of gas manifold, exports low-pressure gas, it is ensured that crust breaking cylinder completes the second half section
Retract action and be in retracted state all the time, had the most both guaranteed that original crust breaking cylinder technological requirement was not changed, and carried again simultaneously
High crust breaking cylinder use gas efficiency, save compressed air, thus reach energy-saving and cost-reducing purpose.
