Abstract
The utility model discloses a monitoring system of an aluminium electrolysis cell crust breaker. The monitoring system is characterized by comprising a signal acquisition unit installed on a crust breaking cylinder, and a signal analysis unit and an alarming unit connected through leads, wherein the signal analysis unit receives the signals transmitted by the signal acquisition unit for analytical judgment and then transmits the signals to the alarming unit arranged in the monitoring occasion. The monitoring system can monitor the working condition of the electrolytic electrolysis cell crust breaking cylinder in time, when a hammer is clamped, or the threaded connection part of the hammer and the cylinder is loosened or falls off, or the hammer is adhered with too much electrolyte, the signals are transmitted to the signal analysis instrument through the signal acquisition device, then the signal analysis instrument make a judgment on the signals, and then an indicator light on site is used for alarming so as to inform the operating personnel of making corresponding treatment. For the monitoring system, not only can the emergent effects caused by hammer clamping be avoided in time and the power consumption is reduced, but also can the crust breaking cylinder is better protected, the using period of the hammer is prolonged and the virgin aluminum quality is ensured.
Description
Technical field
The utility model belongs to the Aluminium Electrolysis field, relates to a kind of novel aluminum cell crust breaker supervisory system specifically.
Background technology
Along with the development of China's electrolysis of aluminum industry, the various controls of electrolyzer are more and more become more meticulous, level of automation is also more and more higher.Multiple spot crust breaking blanking in the middle of the modernization large scale electrolytic cell generally adopts, the crust-breaking chips life cycle is short, changes the frequency height; Cause the burst effect of electrolyzer simultaneously easily because of the folder tup, cause power consumption to increase; Because tup and cylinder generally all adopt and are threaded, after using some cycles, can occur becoming flexible or coming off, if will certainly cause tup to be melted in the electrolyzer, cause the primary aluminum downgrade in case come off; Tup in use often contacts with ionogen, will certainly be stained with some ionogen on tup, if ionogen is too much sticking, can cause the cylinder operation load excessive, also enters into the inner difficulty that increases of electrolyzer to blanking simultaneously.So the crust breaker to electrolyzer is monitored in real time, prolong the work-ing life of crust breaking cylinder, prolong the replacement cycle of tup, reduce the generation of burst effect, improve the primary aluminum quality, it is necessary seeking a kind of not only simple but also economic supervisory system.
Summary of the invention
The problem that the utility model exists at above-mentioned existing large pre-baked cell crust breaker just; and a kind of science that provides, reasonable, energy-conservation, efficient, simple to operate, few, the safe and reliable monitoring device-a kind of novel aluminum cell crust breaker supervisory system of investment; this supervisory system can not only avoid in time because folder tup and the burst effect that causes; reduce power consumption; simultaneously can also the better protection crust breaking cylinder; prolong the life cycle of tup, guarantee the primary aluminum quality.
The purpose of this utility model is achieved through the following technical solutions: crust breaker supervisory system of the present utility model comprises the signal gathering unit that is installed on the crust breaking cylinder, by signal analysis unit and alarm unit that lead connects, and the signal that signal analysis unit transmits by the received signal collecting unit carries out sending alarm unit to after the analysis and judgement.
In the utility model, described signal gathering unit is the travel switch that is arranged on cylinder bottom, and travel switch is installed in cylinder bottom by retaining plate, and carries out spacing monitoring by the travel switch postive stop baffle.
Described signal analysis unit is a timing relay, and timing relay comprises timing relay normally opened contact SJ1 and timing relay coil SJ2.
Described alarm unit is pilot lamp or combined aural and visual alarm, and this pilot lamp or combined aural and visual alarm can be installed in the electrolyzer top, also can be installed in the slot control machine top.
Principle of work of the present utility model is: by install crust breaking system signal gathering device additional on electrolyzer, monitor the working condition of electrolyzer crust breaking cylinder in time, when folder tup or tup appears and become flexible the cylinder threaded connection place, when coming off, or when the sticking ionogen of tup is too much, by signal pickup assembly signal is sent on the signal analysis instrument, the signal analysis instrument is made judgement to signal, report to the police by the pilot lamp at scene again, notify the operating personnel to handle accordingly.
Advantage of the present utility model is:
1. when folder tup or tup occurring and become flexible the cylinder threaded connection place, when coming off, or glue ionogen when too much at tup, can in time report to the police, obtain respective handling;
2, time of fire alarming can suitably be regulated according to practical situation;
3, prolong the work-ing life of crust breaking cylinder;
4, prolong the replacement cycle of tup;
5, reduce the generation of burst effect;
6, improve the primary aluminum quality;
7, investment is little, easy to maintenance, simple to operate, safe and reliable.
