Abstract
The utility model relates to a real-time discharge monitoring system for an aluminium electrolytic tank, belonging to the control technology in the aluminium electrolysis industry. A fresh alumina flow rolling measuring instrument of the real-time discharge monitoring system is arranged on an alumina material conveying pipe between a fresh alumina bin and a main chute of a dust collector, and a first fluorinated alumina rolling measuring instrument and a second fluorinated alumina rolling measuring instrument are arranged on the material conveying pipe of a fluorine loading bin between a fluorine loading bin and a flue. The real-time discharge monitoring system for the aluminium electrolytic tank has the advantages that: (1), the construction difficulty is greatly reduced, on the contrary, the signal stability is improved, and the design and construction costs are reduced; (2), the real-time pressure and blowback monitoring is realized, and a host computer system is ensured to monitor the differential pressure and other status data of the dust collector; (3), the discharging amount and all parameters of the whole conveying system can be monitored and adjusted in real time. The real-time discharge monitoring system can be used for the discharge monitoring in the aluminium electrolysis industry.
Description
Technical field
The utility model relates to a kind of electrolysis of aluminum industry control techniques, specifically relates to a kind of aluminum cell supplying real-time monitoring system.
Background technology
The thing level detecting apparatus that the alumina blanking of electrolysis of aluminum industry adopts aluminium cell hopper top to install is a level switch, be blocking rotary type level switch or tuning-fork type level switch, these two kinds of switches can only simply be judged the ceiling value of material level, can't be according to the accurate controlled oxidation aluminium of material amount addition in the hopper.In the actual production, as long as the high charge level blackout of electrolytic bath feed box, no matter how many interior material actual consumption amounts of hopper is, feeder system is just pressed a certain amount of be charging of the cell and batching, it is reinforced discontented or add the inaccurate of overflow and batching hopper often to occur, cause the waste of aluminum oxide and aluminum fluoride, the molecular ratio in the electrolyzer can not in time be adjusted, and the qualification rate of molecular ratio is very low.Have a strong impact on the maintenance of the ordinary production and the technical qualification of electrolyzer, increased production cost again.The enterprise that also has uses bucket to claim to occupy very big solid space, and is in high empty position and is unfavorable for safeguarding.Of paramount importance is that it can't stablize materials flow, can not throw in fresh aluminum oxide and fluorinated alumina uniformly, all unfavorable to defluorination and electrolysis.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, and a kind of aluminum cell supplying real-time monitoring system is provided.
A kind of aluminum cell supplying real-time monitoring system of the utility model is achieved by following technical proposals: a kind of aluminum cell supplying real-time monitoring system of the utility model comprises fresh aluminum oxide flow rolling gauge, the first fluorinated alumina rolling gauge, the second fluorinated alumina rolling gauge, carry the fluorine storehouse, the fresh aluminum oxide storehouse, the aluminum oxide carrier pipe, the fluorinated alumina carrier pipe, carry fluorine storehouse carrier pipe, fly-ash separator master chute, flue, described fresh aluminum oxide flow rolling gauge is arranged on the aluminum oxide carrier pipe between fresh aluminum oxide storehouse and the fly-ash separator master chute, and the described first fluorinated alumina rolling gauge and the second fluorinated alumina rolling gauge are arranged on carries carrying on the carrier pipe of fluorine storehouse between fluorine storehouse and the flue.
A kind of aluminum cell supplying real-time monitoring system of the utility model has following beneficial effect compared with prior art: because the utility model has adopted the rolling gauge that aluminum oxide and fluorinated alumina blanking are carried out real time measure, make the materials flow of blanking amount stable, the Measuring Precision height, and rolling gauge volume is little, convenient for installation and maintenance, control flexibly, as long as after setting flow on computers, rolling gauge basis is adjusted after comparing when having the blanking amount now and presetting blanking automatically, whole process need not artificial participation, and the flow control error is in 5 ‰; The material setting range can be from 0 ton/hour～30 tons/hour.The advantage of a kind of aluminum cell supplying real-time monitoring system of the utility model: 1) greatly reduce difficulty of construction, on the contrary, improved signal stability, reduced design and construction cost; 2) realize that pressure and blowback detect in real time, guarantee that master system can monitor status datas such as fly-ash separator pressure reduction; 3) can monitor and adjust blanking amount and whole delivery system parameters in real time.The utility model can be applicable to the blanking prosecution of electrolysis of aluminum industry.
