Abstract
For a crust breaker for aluminium cell, the described crust breaker for aluminium cell comprises the switch electromagnetic valve be installed in described inlet pipe, and described switch electromagnetic valve comprises inlet, outlet, the first control coil port and the second control coil port.Described switch electromagnetic valve comprises inlet, outlet and connects with described inlet pipe, described first control coil port is electrically connected with described crust breaking end, described second control coil port is electrically connected with described negative busbar, is in series with current-limiting resistance between described second control coil port and described negative busbar.Compared with correlation technique, the crust breaking end of crust breaker that the utility model is used for aluminium cell is once contact ionogen in decline process, and control coil has electric current to pass through, now closed electromagnetic valve source of the gas, crust breaking end stops moving downward, thus avoids the sticky bag that crust breaking end immerses ionogen generation.And the length no requirement (NR) to crust breaking end, crust breaking end does not immerse ionogen, can extend the work-ing life of crust breaking end.
Description
[technical field]
The utility model relates to technical field of aluminum electrolysis, particularly relates to a kind of crust breaker for aluminium cell.
[background technology]
Current is fixed journey system for the crust breaker in the crust breaker of aluminium cell, during crust breaking, crust breaking end enters when ionogen is mentioned and sticks up a large amount of ionogen, and aluminum oxide contacts with ionogen and is bonded at crust breaking end surface during blanking, form sticky bag, sticky wrapping in constantly is grown up in crust-breaking & baiting process frequently, the defect of present technology: (1) existing crust-breaking & baiting mechanism easily causes the sticky bag of crust breaking end, and the hitting power of the crust breaking end unit surface after sticky bag diminishes, and getting through shell face difficulty increases.(2) after the sticky bag of crust breaking end, bump against sticky wrapping and disperse everywhere during alumina blanking, the actual aluminum oxide entering feed opening reduces.(3), after the sticky bag of crust breaking end, sticky bag must be destroyed with drill rod by electrolysis procedure work, and this increases operative employee's labour intensity on the one hand, lays the sticky bag come on the other hand and enters ionogen and sedimentation and bottom land, increase bearth precipitation, affect cell life.
Therefore, be necessary to provide a kind of crust breaker for aluminium cell newly to solve the problems of the technologies described above in fact.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of crust breaker for aluminium cell.
A kind of crust breaker for aluminium cell of the utility model, comprise the negative busbar be arranged in aluminium cell, be arranged on the crust breaking end above aluminium cell, be installed on the cylinder for driving described crust breaking end translational motion above described crust breaking end, with described cylinders for described cylinder provides inlet pipe and the escape pipe of source of the gas, wherein, the described crust breaker for aluminium cell also comprises the switch electromagnetic valve be installed in described inlet pipe, described switch electromagnetic valve comprises the first control coil port, second control coil port and entering of connecting with described inlet pipe respectively, air outlet, described first control coil port is electrically connected with described crust breaking end, and described second control coil port is electrically connected with described negative busbar, is in series with current-limiting resistance between described second control coil port and described negative busbar.
Preferably, described switch electromagnetic valve is direct-acting electromagnetic valve.
Compared with correlation technique, the crust breaking end of crust breaker that the utility model is used for aluminium cell is once contact ionogen in decline process, and control coil has electric current to pass through, now closed electromagnetic valve source of the gas, crust breaking end stops moving downward, thus avoids the sticky bag that crust breaking end immerses ionogen generation.And the length no requirement (NR) to crust breaking end, crust breaking end does not immerse ionogen, can extend the work-ing life of crust breaking end.
[accompanying drawing explanation]
Fig. 1 is the one-piece construction schematic diagram of a kind of crust breaker for aluminium cell of the utility model.
[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
See Fig. 1, a kind of crust breaker for aluminium cell, comprise the negative busbar 1 be arranged in aluminium cell, be arranged on the crust breaking end 4 above aluminium cell, be installed on the cylinder 5 for driving crust breaking end 4 translational motion above crust breaking end 4, for cylinder 5 provides inlet pipe 6 and the escape pipe 7 of source of the gas, wherein, crust breaker for aluminium cell also comprises the switch electromagnetic valve 8 be installed in inlet pipe 6, and switch electromagnetic valve 8 comprises the first control coil port 83, second control coil port 84 and the inlet mouth 81 of connecting with inlet pipe 6, air outlet 82.First control coil port 83 is electrically connected with crust breaking end 4, and the second control coil port 84 is electrically connected with negative busbar 1, is in series with current-limiting resistance 9 between the second control coil port 84 and negative busbar 1.Switch electromagnetic valve 8 is direct-acting electromagnetic valve.
In electrolyzer, current enter 12 is electrically connected with anode 2.Anode 2 is placed in ionogen 3, and current output terminal 13 is connected with negative busbar 1, negative electrode 14 electricity, and negative electrode 14 is placed under aluminium liquid 10.During work, air-flow flows into cylinder 5 from inlet pipe 6 through direct-acting electromagnetic valve inlet mouth 81, air outlet 82, cylinder 5 cylinder bar is driven to stretch out, thus drive crust breaking end 4 to move downward, after breaking shell face 11, during contact ionogen 3, crust breaking end 4-direct driving type electromagnetic valve coil-current-limiting resistance 9-negative electrode 14 bus 1-anode 2-ionogen 3 forms loop, direct driving type electromagnetic valve coil is got the voltage of electric tank cathode 14 current enter 12 and current output terminal 13 supply, thus disconnecting inlet pipe 6 gas circuit, crust breaking end 4 stops moving downward.Control source of the gas is opened, and crust breaking end 4 moves upward and departs from ionogen 3, and on electromagnetic valve coil, no current passes through, and source of the gas opened by magnetic valve, for crust breaking is prepared next time.
Compared with correlation technique, the crust breaking end of crust breaker that the utility model is used for aluminium cell is once contact ionogen in decline process, and control coil has electric current to pass through, now closed electromagnetic valve source of the gas, crust breaking end stops moving downward, thus avoids the sticky bag that crust breaking end immerses ionogen generation.And the length no requirement (NR) to crust breaking end, crust breaking end does not immerse ionogen, can extend the work-ing life of crust breaking end.
Above-described is only embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection domain of the present utility model.
