The present invention is directed to explore a kind of dispensing carbonaceous fuel identical with carbon body electrolytic anode material, do not change electrolytic aluminium
Slot original electroreduction atmosphere removes tup glue by flame baking, and hot melt drippage returns the flow and method of slot, plays
The effect of line scafing tup.
The purpose of the present invention is achieved through the following technical solutions, firstly, when observation tup condensation is sticked object and increased,
Pause executes crust breaking program, and tup is made half way promotion, is hovered on scafing position；Then, by honeycomb carbonaceous (lightweight
Easy fuel) it clamps in the fused electrolyte liquid cave that push is formed into crust breaking, it swims on melting matter liquid level；With that is, honeycomb
Shape carbonaceous is fired by high-temperature fusion particle, and flame alters burning, packet splicing tup above direct baking from honeycomb hole；Due to cohering mixture

Sequence；The purification carbonaceous fuel that the present embodiment is launched is identical as carbon body electrolytic anode material, does not change aluminum electrolytic tank reduction atmosphere
It encloses.
It is divided into two working regions in usual aluminum electrolytic tank workshop, each area substantially and is equipped with 74 slots series；Usually electrolysis
It is about 17.5 meters of aluminium slot long, 4.9 meters wide, about 2.9 meters of aluminium separation；Single aluminum electrolytic tank configuration air supply pipe all the way, respectively at six
Cylinder crust breaking point, feed point at corresponding six, provide 6~8Bar power air supply source.Sampling action is pressed: 1,3,5 odd points are first held
A seconds crust breakings of row, 1 after B seconds, 3,5 blankings, then 2,4,6 even number point crust breakings, subsequent 2,4,6 blankings, interval repeat after 130 seconds
It executes.
Below with reference to attached drawing, a preferred embodiment of the present invention will be described in detail；It should be appreciated that preferred embodiment
Only for illustrating the present invention, rather than limiting the scope of protection of the present invention.
As shown in Figure 1, crust breaking cylinder right angle setting is relatively living shown in aluminium slot crust breaking cylinder piston system main component figure
It is lower beyond the Great Wall to demarcate, there are upper stomata and air holes respectively, upper stomata is connect with No. 4 gas circuit mouths of gas control two-position five-way valve, air holes and 2
The connection of number gas circuit mouth, No. 1 gas circuit mouth of gas control two-position five-way valve connect 6~8Bar power gas supply source capsule.
When crust breaking, gas control two-position five-way valve 1-4 gas circuit is logical, and air supply source is to crust breaking upper cylinder pressurising, while 2-3 gas circuit
Logical, lower cylinder externally discharges gas, under the drill steel tup gravity collective effect that cylinder piston stroke thrust is connected with piston, piston
Fast driving tup is downward, realizes strong crust breaking.
After executing A second, sending proposes hammer instruction, and gas control two-position five-way valve switches to 1-2 gas circuit and leads to, and air supply source is to mentioning under hammer
Cylinder pressurising, while 4-5 gas circuit is logical, upper cylinder externally discharges gas, under the promotion of cylinder piston stroke, overcomes the pricker of piston connection
Power that wiper hammer is nose heave, piston slowly mention hammer upwards.
Similarly, it is also correspondingly configured with a set of charging pneumatic control system, after issuing crust breaking gas control and instructing B seconds, baiting valve commutation,
It drives lower material cylinder by crust breaking cave, adds aluminium oxide or fluoride salt material, crust breaking and charging timing linkage.
Crust breaking cylinder end of travel is equipped with surge chamber, and cylinder air pressure bolster, which compresses, remains air in surge chamber, as gas
Pad prevents piston and end bottom cover collision；Screw thread or welded connecting are used between tup and piston drill steel, it is desirable that tup must reach molten
Melt electrolyte solution, otherwise easily occur that crust breaking is not in place, and feed inlet is not opened, material cannot be added in time, leads to that anode effect occurs；So
And tup is longer, causes its soaking time in fused electrolyte liquid longer, so as to stick object relatively more for electrolyte melting, makes
It grows up at " packet splicing ", reduces crust breaking efficiency.
Crust breaking cylinder acts 700 times or more round the clock, and each tup is immersed in up to 950 DEG C of melt 2~3 seconds, melt
It is made of 90wt% ice crystal, 5wt% aluminium oxide and 5wt% additive, causing tup to add up, soaking time is longer, electrolyte is molten
Melt and stick relatively more object, cleaning " packet splicing " time-consuming effort, frequently even replace the reason of series of problems such as tup and have: setting executes
Crust breaking gas control instructs duration excessive, while multi cylinder inflation drags down gas transmission pipeline net work pressure, and it is slow that piston mentions hammer；The pricker of piston connection
Wiper hammer head is overweight, and starting inertia is too big；Area is less than upper area under cylinder piston, and born lifting force is insufficient.
There are about 2000mm long for usual piston stroke, the ice crystal institute on the one hand resolved by sodium oxide molybdena, calcium oxide, magnesia
The bulk of the electrolyte ingredient of composition constantly changes, and will cause surface crust hardness and viscosity is different；On the other hand, melting electricity
Solution matter liquid has 100mm liquid fluctuating range with production adjustment, 500 DEG C of electrolyte case temperature or so, therefore, hammers needed for crust breaking
Dynamics and insertion effective depth will also follow regulation.
Up to the present, it to guarantee the effective insertion depth of crust breaking process, inevitably contacts, impregnate, condensing and stick object,
In addition, considering not enough, to reduce tup delay and take effective measures, help to hammer efficiency is proposed to improve the pneumatic system of crust breaking efficient design
" packet splicing " is pushed away to become larger；The present invention early period not can avoid tup condensation stick object aiming at the problem that, beaten in the later period using flame baking
The mode of shell packet splicing tup, hot melt, which melts, sticks object, plays the effect of online scafing, without unloading tup, effectively drops
Low " packet splicing " removes difficulty, improves operability and convenience.
Specific crust breaking process is as follows: it is hard to punch electrolyte for gas control two-position five-way valve actuating cylinder, piston fast driving tup
Shell can touch fused electrolyte liquid；After waiting A seconds, gas control two-position five-way valve completes switching, and piston execution proposes hammer movement,
Drill steel tup is being offset from after gravity, is slowly leaving melt layer.
It executes in former crust breaking program, and no-trump tup makees half way promotion, " packet splicing " tup hovers above electrolyte shell
The step of, the scafing bit function hovered over above flame need to be newly established.
Automatic crust breaking program is transferred to manual mode for crust breaking controller by there are many ways to adding scafing position,
Button is grasped by hand and controls gas control two-position five-way valve, manipulates lower cylinder pressurising amount, proposes hammer half way hovering；For gas control two five
Port valve forces to stir the included reversing bar of valve body；It can also additionally increase logic control implementations realization.
It is illustrated in figure 2 carbonaceous fuel launch process schematic diagram, between " packet splicing " tup and electrolyte shell of hovering,
Artificial stock clamping by honeycomb carbonaceous, the easy fuel push of lightweight, is launched in the melting matter cave formed into crust breaking.
Additional to increase maintenance solenoid valve in Fig. 2, setting supplies source capsule upstream, on-off electromagnetism specially open in usual in power
Valve, in power loss, solenoid valve is logical opens, and is in opening state for gas circuit, does not influence the normal work of cylinder piston；The electricity when obtaining electric
Magnet valve open circuit, in an off state for gas circuit, cylinder piston operation will suspend in mid air, and temporarily keep off-position, stationary, and with
Two-position five-way valve state is unrelated.Maintenance solenoid valve state and the crust breaking program that crust breaking controller executes are chain.
Crust breaking cylinder acts 700 times or more round the clock, and each tup is immersed in up to 950 DEG C of melt 2~3 seconds, accumulation
It is relatively more that duration causes electrolyte melting to stick object.
When observing that tup condensation sticks object and gradually increase, influence crust breaking punch efficiency when, maintenance electromagnetism is pressed in selection
Valve power transmission button executes electric, shutdown movement；Due to having cut off power air supply source, lower cylinder pressurising pause, piston will keep former
Shape rests on the middle position for mentioning hammer stroke, is considered as tup scafing position；This moment, it temporarily interrupts and executes crust breaking process.
It is illustrated in figure 3 the easy fuel appearance schematic diagram of honeycomb carbonaceous, carbonaceous fuel is integrated with the inflammable feature of lightweight,
It is made of purification carbon dust, it is identical as carbon body electrolytic anode material, aluminum electrolytic tank reduction atmosphere will not be changed after dispensing.
Specifically, by purification carbon dust production molding, appearance is cylindrical, and inside has vertically to through hole, i.e. honeycomb shape, easily
Burning is altered from honeycomb hole in flare；Then, honeycomb carbonaceous blocks are pre-sintered, make it have micro- stomata, cavernous body, made light
After quantification treatment, it can float on fused electrolyte liquid level；Finally, making honeycomb carbonaceous blocks by addition or immersion way
Volatility combustion adjuvant is adsorbed, which can be easy to adjust carbonaceous fuel burning point, with melting with flame high-temperature evaporation, evaporation
Electrolyte coagulation layer case temperature is suitable, and improves combustion calorific value, accelerates temperature-rise period.
During electrolytic aluminium, following electrochemical reaction: Al occurs2O3(raw material)+C (electrode) → (electric energy+electrolyte is made
With lower generation :) → Al (product melt)+CO2(discharge gas).
From tup " packet splicing " structure of matter, by three kinds of mixtures such as electrolyte in layer, aluminium oxide and carbon slag
Composition；Wherein, electrolyte, that is, ice crystal, about 1009 DEG C of fusing point；Aluminium oxide is raw material, under conditions of ice crystal is as solvent,
In up to 950 DEG C of aluminum electrolytic tanks, it is in solution status；Carbon of the carbon slag on electrolytic anode removes body, contains
Amount is few, free with liquid electrolyte.
From aluminum electrolytic tank Temperature Distribution, 500 DEG C of electrolyte case temperature or so, 950 DEG C of aluminum electrolytic tank melt temperature
Left and right, therefore, intermediate molten electrolyte matter liquid is between 500-950 DEG C.
It is illustrated in figure 4 packet splicing tup schematic diagram above flame baking, the easy fuel dispensing of lightweight honeycomb carbonaceous is arrived
Behind the cave that crust breaking is formed, cave provides perimeter constraint environment, and Floating Height mainly determines by fused electrolyte liquid level, bottom with
" packet splicing " tup of 500~950 DEG C of melting matter contact, top and hovering keeps appropriate baking distance.
Common about 300~700 DEG C of burning point of carbonaceous material, the easy fuel burning point pre-adjustment of lightweight honeycomb carbonaceous of the present embodiment
It to 500 DEG C or so, is matched with 500 DEG C of electrolyte case temperature, that is, is easy to adjust carbonaceous fuel burning point, solidified with fused electrolyte
Layer case temperature is suitable；After melting matter heat transfer, it can be ignited in the short time, and under combustion adjuvant power-assisted, since bottom,
It spreads rapidly upward；In semi-open electrolytic cell and under atmospheric environment, the flame temperature that burning is altered from honeycomb hole is much larger than
1000 DEG C, direct baking top " packet splicing " tup leads to solid-state glue fast endothermic, heating.
Next, being illustrated in figure 5 tup glue hot melt drippage returns to aluminum electrolytic tank schematic diagram, mixed tup coheres
Only 1009 DEG C of ice crystal fusing point highest in object, under lasting baking, outer layer takes the lead in being hot-melted, and glue becomes liquid state, in gravity
Lower drippage is driven, is returned in aluminum electrolytic tank again；Subsequent internal layer glue continues to be hot-melted, dripped until glue is whole,
It removes.
In addition, crust-breaking chips is made of carbon steel, and about 1500 DEG C of carbon steel fusing point or more, under semi-open atmospheric environment, fire
Flame is difficult directly to melt carbon steel.Also, as carbonaceous fuel constantly consumes, the lightweight on fused electrolyte liquid level is swum in
The easy fuel of honeycomb carbonaceous is gradually shortened, and in the case that tup maintenance position immobilizes, flame height can decline, and toasts intensity
Gradually weak, tup, which further heats up, to be become difficult.
When observing that tup condensation sticks object and remove substantially, it is no longer necessary to when continuing flame baking, press maintenance solenoid valve
Cut-off button executes power loss, opens movement；Due to continued access power air supply source, lower cylinder pressurising is connected, and piston is with will continue
It is promoted, a high position for hammer stroke is proposed until resting on, the crust breaking process temporarily interrupted is able to restore to execute.
It is illustrated in figure 6 aluminium slot crust-breaking chips and returns high-order beginning new round crust breaking action schematic diagram, maintenance solenoid valve rises
To be pause and restore crust breaking process trigger action.
Then, the easy fuel of remaining lightweight honeycomb carbonaceous or by continue burn, or will be by tup crust breaking when smash, smash
Broken carbonaceous residue is free in fused electrolyte liquid, consistent with the carbon removing granule on electrolytic anode, aluminum electrolytic tank
Reduction reaction atmosphere maintains, and the variation on substance does not occur.
The present embodiment also provides a kind of aluminium slot crust-breaking chips scafing method, using flame baking crust breaking packet splicing tup side
Formula, hot melt, which melts, sticks object, plays the effect of online scafing；Firstly, pause is held when observation tup condensation is sticked object and increased
Tup is made half way promotion, hovered on scafing position by row crust breaking program；Then, the easy fuel of lightweight honeycomb carbonaceous
Clamping push enters in the fused electrolyte liquid cave that crust breaking is formed, and swims on melting matter liquid level；With that is, the easy fuel quilt of carbonaceous
The combustion of high-temperature fusion particle, flame alter burning, packet splicing tup above direct baking from honeycomb hole；Due to cohering mixture fusing point not
Height also has certain initial temperature, will be hot-melted, and drippage liquid returns in aluminum electrolytic tank again；Finally, tup to be seen is solidifying
Knot sticks after object removes substantially, withdraws scafing position, and tup automatic lifting returns high-order, then restores execution crust breaking program；This
