Description
Technical field:
The present invention relates to the method for opening and closing and the device of the prebaked anode cell short-circuit port that a kind of Aluminium Electrolysis uses, particularly relate to a kind ofly, belong to aluminium electrolytic cell short-circuit port open and close technology field at the potline not method for opening and closing and the device of large-scale prebaked anode cell short-circuit port under the power-off condition.
Technical background:
At present, the domestic large-scale roasting electrolyzer that gives all adopts when overhaul stops groove and manually opens the short circuit mouth, extracts the insulation plate, the schedule of operation of the short circuit mouth that manually closes again.Because electrolyzer riser bus bar when producing has very big electric current, therefore, such operation will cause short-circuit block and bus generation sparking phenomenon, thereby the potential safety hazard of bringing influences stably manufactured.For operational safety, the normal employing has a power failure or falls the method for electric current whole electrolytic series, finishes the mounting or dismounting work of short circuit mouth seal.The method that electrolytic series has a power failure is that electrolytic series is had a power failure in short-term, promptly by manually unclamping the bolt of short circuit mouth, takes out insulcrete, and the short-circuit busbar that closes is tightened joint bolt; The method of electric current falls in electrolytic series, promptly is that each short circuit mouth electric current of control is not more than 10KA, chargedly carries out short circuit operation.Electrolyzer as 300KA has 5 short circuit mouths, and its potline current will be reduced to 50KA, and simultaneously, 5 short circuit mouths need keep synchronously when operation as far as possible, in order to avoid form the electric current bias current, cause the too high generation spark phenomenon of local current.Above-mentioned two kinds of ways all exist the schedule of operation complexity, effort is time-consuming and influence the electrolyzer stably manufactured, and electrical network are caused the problem of enormous impact.Moreover, need every year the electrolyzer number of overhaul quite a lot of, frequent electrolytic series stops sending electricity or falls electric current, certainly will cause difficulty to electrolysis production, influences production efficiency.
Summary of the invention:
The objective of the invention is: provide a kind of outspoken speed of short circuit that can under switch-on regime, realize to open and close, and can prevent the phenomenon of short-circuit block and riser bus bar generation sparking and easy-to-operate, do not influence the method for opening and closing and the device of the prebaked anode cell short-circuit port of production, particularly a kind of method for opening and closing of large-scale prebaked anode cell short-circuit port and device, to overcome the deficiencies in the prior art, guarantee safety operation and enhance productivity.
The present invention is achieved in that the method for opening and closing of prebaked anode cell short-circuit port of the present invention is: in the time need carrying out the closed connection of short circuit to the short circuit mouth of prebaked anode cell, pneumatic quick motion device of the other installation of riser bus bar on prebaked anode cell earlier, the short-circuit busbar at short circuit mouth place is connected on action component that then will this pneumatic quick motion device and the riser bus bar, make the action component of pneumatic quick motion device can drive the short-circuit busbar action, to be installed in the bolt nut that is used to be connected and fixed short-circuit busbar on the riser bus bar then unclamps, controlling pneumatic quick motion device makes short-circuit busbar (6) and insulcrete (11) break away from riser bus bar (3) fast, after insulcrete (11) between riser bus bar (3) and the short-circuit busbar (6) taken off, can make short-circuit busbar be pressed on the riser bus bar fast by the action of controlling pneumatic quick motion device, after will being installed in the bolt nut that is used to be connected and fixed short-circuit busbar on the riser bus bar then and locking again, promptly finish the short circuit closed procedure of short circuit mouth; When needs are opened the short circuit mouth of the prebaked anode cell that short circuit connects, after will being installed in the bolt nut that is used to be connected and fixed short-circuit busbar on the riser bus bar earlier and unclamping, short-circuit busbar is broken away from fast and the contacting of riser bus bar, insulcrete (11) is inserted between riser bus bar (3) and the short-circuit busbar (6) then, make short-circuit busbar (3) and insulcrete (11) be pressed on the riser bus bar fast by the action of controlling pneumatic quick motion device again, after being installed in the bolt nut locking that is used to be connected and fixed short-circuit busbar on the riser bus bar, promptly finish the short circuit open operation of short circuit mouth.
When the short circuit closed procedure of finishing the short circuit mouth or after finishing the short circuit open operation of short circuit mouth, its pneumatic quick motion device is withdrawn from prebaked anode cell.
The pneumatic quick motion device of prebaked anode cell short-circuit port that is used for method of the present invention is: it comprises pneumatic cylinder (1), piston axle head at pneumatic cylinder (1) is connected with guide arm (4), front end at guide arm (4) is connected with an energy by being bolted to the retaining plate (8) on the riser bus bar by rotating shaft (7), and the both sides up and down of going up rotating shaft (7) at guide arm (4) are connected with a switching pull bar (5) respectively by shipping and reselling on another market, and are connected with an energy by being bolted to the web plate (9) on the short-circuit busbar (6) on switching pull bar (5).
Be connected with the detachable bearing (2) on the grillflooring (10) between a groove that can be fixed on prebaked anode cell on the pneumatic cylinder (1).
When using device of the present invention, earlier detachable bearing (2) is installed between the other groove of the riser bus bar (3) of prebaked anode cell on the grillflooring (10), retaining plate (8) and web plate (9) are separately fixed on riser bus bar (3) and the short-circuit busbar (6) by bolt, when needs are opened the short circuit mouth, with manually the bolt nut that is used to be connected and fixed short-circuit busbar on the riser bus bar being unclamped, operate pneumatic cylinder (1) action then, power is delivered on the guide arm (4), because the center of guide arm (4) is fixed on the riser bus bar (3), thereby power can be delivered to equably on the switching pull bar (5) of both sides, open and close pull bar (5) and drive short-circuit busbar (6) moment disengaging riser bus bar (3), realize the outspoken speed of short circuit is opened.When needs closed the short circuit mouth, operation pneumatic cylinder (1) reverse motion drove guide arm (4) and opens and closes pull bar (5), and short-circuit busbar (6) moment is combined with riser bus bar (3), realized the outspoken fast closure of short circuit.
The invention has the beneficial effects as follows: by the action of operation pneumatic cylinder, the time that reaches short circuit ora switch is short as far as possible, thereby avoids the phenomenon of sparking between short-circuit busbar (6) and riser bus bar (3) to take place, and ensures safety in production, and enhances productivity.
