Description
Technical field:
The present invention relates to a kind of on-line continuous proofing unit of anodic current distribution of aluminium cell.
Background technology:
For a long time, it is to perplex the bottleneck of aluminum electrolysis process equipment technology and automatic control technology great development that the processing parameter on-line continuous of aluminium cell detects problem always, and especially anodic current distributes, and to detect be to belong to all to need every day and per tour in the daily production operation of the every platform trough of electrolytic series the processing parameter measured all the more so.
For many years, primitive method per tour every day that the anodic current distribution measuring of home and abroad aluminium cell adopts the equidistant pressure drop of artificial use to measure rod is always measured, it takes time and effort, be unfavorable for improving production operation and management condition, particularly when electrolyzer generation abnormal conditions such as unusual groove condition such as voltage swing, anode pathology, cause when distribution of current is offset in the groove, Continuous Tracking is measured anodic current and is distributed, in time understanding and the analysis vat condition variation tendency and the measure that takes some countermeasures, is that production operator and manager's gutter condition are expected always; The anodic current distribution automatic detection signal that particularly will change is at any time sent into computer automatic control system continuously, realizes online detection and monitoring that anodic current distributes, and present manual operation is to be beyond one's reach.In recent years, domestic in order to solve the anodic current distribution measuring problem of calcination between the starting period, once developed adopt the nuditing wire head by nut be bolted to the interim method of carrying out the anodic current measure of spread on the anode aluminium guide bar, when its weak point is change poles, at any time need the artificial unloading and reinstall, workload is big, operates dangerous.
Summary of the invention:
The objective of the invention is: a kind of equidistant pressure drop on-line measurement device that is used for the prebaked cell for aluminum-reduction anode rod is provided, can be groove control system Continuous Tracking anodic current distribution situation, and provide online detection data to groove condition diagnosis, thereby realize the automatic detection that anodic current distributes, to solve the difficult problem that existing Equipment Technology exists.
The present invention constitutes like this: it comprises conical contact (1), positioning spring (2), and locating sleeve (3), base (4), conical contact (1) are contained in the locating sleeve (3), and its rear portion is connected with positioning spring (2); Locating sleeve (3) is connected with the front end of threaded sleeve (5), and base (4) is connected with the rear end of positioning spring (2) and threaded sleeve (5); There is connector lug (6) rear end of base (4), and itself and threaded sleeve are fixed on the angle bar frame (8) by flange and insulating mat (7).
Conical contact (1) top contact is that small circular is spherical.
Between taper contact (1) and positioning spring (2), between positioning spring (2) and the base (4) be metal (welding) but electroconductibility be connected.
Between locating sleeve (3) and the threaded sleeve (5), between threaded sleeve (5) and the base (4) for being threaded.
Connector lug (6) is welded to connect with base (4); Connector lug (6) adopts screw rod to be connected outer guide line (9) with the nut mode.
The present invention is applicable to that respectively organizing the anodic current distributing on-line measurement on the groove of all kinds of prebakeds cell for aluminum-reduction uses.But be characterized in life-time service, and simple in structure, be easy to install, safeguard convenient, can be electrolytic series and realize that the monitoring automatically that distributes of the anodic current of electrolyzer provides practical in good time online test method.
Electrolytic Aluminum Series with 288 320kA grooves of 250kt annual capacity is an example, behind employing the present invention, measures once by class Three's per tour every day 2 people, and year can be saved 2190 person-times of manpowers.The on-line tracing that distributes by anodic current detects control, can reach the optimization processing parameter, the unusual effect of gutter condition and raising efficiency index.As reduce the voltage fluctuation measuring and calculating of 1 hour 100mV every day by every groove, year can be saved power consumption 8,064 ten thousand degree, and the raising of efficiency index, thereby productivity effect in addition is fairly obvious.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment:
In actual applications; one cover test set generally is made up of two groups of measuring apparatuss; can record the equidistant pressure drop signal of anode rod like this; the installation range finding of two groups of measuring apparatuss is determined according to installation site on actual process and the groove; generally can be installed in the anode aluminium busbar or close for a short time on the jig bearing; measure lead (high temperature resistant) and can be connected to the slot control machine input terminus, carry out signal transmitting and data processing by the cable protecting sleeve grouping.
Conical contact of the present invention (1) is the acquisition of signal element, main metallic aluminium surface of being responsible for the contact anode rod, and pass tested voltage signal back.Adopting pyramidal structure can make contact is a contact, to improve measuring accuracy, also makes things convenient for the turnover displacement of anode rod simultaneously.Hinder its slip for preventing that conical contact tip is too sharp, and damage the aluminium guide bar surface, it is spherical that the tapered tip contact can be processed into small circular.
Positioning spring (2) utilizes spring to have two big characteristics of elastic pressure and flexible structure, both can guarantee the compactness that contacts of conical contact and tested surface, simultaneously when anode rod is done level and vertical translation, can in time finely tune the relative measurement position of taper contact (1) and tested surface again, improve the application flexibility and the adaptability of detecting element.
Locating sleeve (3) is used to adjust the initial measurement position of taper contact and located.
Base (4) is responsible for fixedly taper contact (1), positioning spring (2) and connector lug (6), and device is fixed on the angle bar frame by flange and insulating mat (7) with the threaded sleeve combination.Between taper contact and the spring, can adopt welding between spring and the base, so that measured signal can be passed on the wire head.
Threaded sleeve (5) is responsible for connecting locating sleeve (3) and base (4).For being threaded, this mode of connection can be convenient to adjust the measuring position between locating sleeve (3) and the threaded sleeve (5), between threaded sleeve (5) and the base (4).
Connector lug (6) is welded to connect with base (4), adopts the fixing outer guide line (9) of screw rod and nut mode.
Insulating mat (7) is responsible for the electric insulation between measuring apparatus and angle bar frame (8).
