Electrobath anode limiting pulse counting method and device

Abstract

The invention discloses a method and a device for counting pulses of an anode in an electrolytic cell. When the anode is raised or dropped in normal positions, the anode drives and rotates a pulse induction wheel, and drives and rotates a limit counting wheel and counts the pulse; the pulse induction wheel drives the pulse induction head to induce the anode motion pulse signals; an upper limit lump and a lower limit lump are positioned on the limit counting wheel, so when the anode is raised to the upper limit, the upper limit induction head induces the upper limit position signal by the upper limit lump; and when the anode is dropped to the lower limit, the lower limit head induces the lower limit position signal by the lower limit lump. By the signal output of the induction head, the pulse induction head can stop sending out the anode motion pulse once the anode moves to the limit positions. The method and the device has the advantages of using flexibility, working reliability, simple structure, high pulse signal precision, installation and debugging convenience.

Description

technical field [0001] The invention relates to a method and a device for detecting limit position pulse counting of an electrolytic cell anode for limit protection and counting of the up and down movement of the anode of an electrolytic cell, and belongs to the technical field of position protection and counting of the anode limit of an electrolytic cell. Background technique [0002] In the control of the up and down movement of the anode of the electrolytic cell, it is required to set the upper and lower limit switches on the electrolytic cell to prevent vicious accidents such as pulling the groove, pressing the groove and destroying the busbar; an anode pulse generator is also required to feed back the anode rising / falling action, And monitor the anode action range during manual voltage adjustment, aluminum tapping, effect extinguishing and other operations. In the prior art, the main function of the anode pulse generator mainly composed of a proximity switch and a gear ...

AI Technical Summary

Problems solved by technology

With the improvement of electrolytic cell control requirements and the change of electrolytic cell transmission mechanism, the original transmission output shaft only generates one anode moving pulse after one rotation, which can no longer meet the accuracy requirements.
