Abstract

The utility model discloses a slotting and chamfering device for four sides of the bottom of an anode carbon block, which comprises a die sleeve (1), a movable side die plate (2), a lug (3) and a fixed lower die plate (4). The lug is fixed at the bottom of the die sleeve (1), the movable side die plate (2) is in hinge connection with the lug (3) and the die sleeve (1) is installed on the fixed lower die plate (4). The fixed lower die plate (4) comprises a slotting die plate (5), a chamfering die plate (6) and a fixed base plate (7), wherein the slotting die plate (5) and the chamfering die plate (6) are vertically arranged on the fixed base plate (7). Utilizing the device to chamfer the bottom of the anode carbon block can reduce carbon slag, lighten the weight of a monoblock anode, and reduce unit consumption of the anode. The slotting and chamfering device for the bottom of the anode carbon block device can quicken electrolysis-generated gas emission, lower a bubble voltage drop of the anode and power consumption and improve anode effects, thereby enhancing electrolytic reactions and increasing the yield of aluminum.

Description

The device of a kind of fluting and bottom chamfer anode block

Technical field

The utility model relates to a kind of device of anode block, particularly relates to the device of a kind of fluting and bottom chamfer anode block.

Background technology

At present, along with China is more and more tighter to the requirement of electrolytic aluminium energy-saving and emission-reduction, consumption reduction synergy, and electrolytic aluminium production process is not at present under situation that essence changes all also takes place in the whole world, and this just requires technically the many-sides such as production technology, anode block, electrolytic cell to electrolytic aluminium to improve.Because anode surface produces gas such as O in aluminium electrolysis process ₂, CO ₂, CO etc. reduce anode life thereby be mixed with the inadequate carbon of electrolysis in its gas, and form air film at anode surface, cause segment anode and electrolyte to isolate, and influence aluminium electroloysis efficient, thereby reduce aluminium output.The right angle is all adopted on simultaneously traditional four sides of anode block and the transition limit of bottom at present, and in electrolytic process, according to use experience, this right angle part very easily oxidation takes place and falls slag, pollutes electrolyte, increases the generation of electrolytical carbon containing accident and sick groove.

The utility model content

The technical problem that the utility model solves is: in aluminium electrolysis process, anode surface produces gases affect aluminium electroloysis efficient and anode block bottom straight flange easily oxidation takes place and falls slag, and the anode block device of a kind of fluting and bottom four limit chamferings is provided.

The technical solution of the utility model: it comprises die sleeve, active side template, ear seat, fixing lower bolster, the ear seat is fixedly connected on the die sleeve bottom, active side template and ear seat are hinged, die sleeve is lifted on fixedly on the lower bolster, fixedly lower bolster is made up of fluting template, chamfering template and fixed base plate, and fluting template and chamfering template are vertically mounted on the fixed base plate.

Described fluting template, chamfering template respectively have 2 and parallel to each other.

The active side template of described center of gravity off-centre has 2 and symmetry installation.

Described fluting template is released direction along anode block constant slope, and promptly a point is than the high 10～20mm of b point.

Before the die sleeve filling anode paste, the utility model is assembled on the make-up machine shake table by technical scheme, behind die sleeve filling anode paste, the startup of make-up machine shake table is vibrated, the chamfering on four limits, anode block bottom this moment and the twice of bottom are recessed in the vibration processes and the anode block one-shot forming, when vibration moulding finishes when carrying out the demoulding, die sleeve is raised, anode block after the moulding is stayed on the make-up machine shake table by the self gravitation effect, the active side template is opened the realization demoulding rapidly in the revolution of anode block weight effect lower edge hinge simultaneously, when die sleeve rises to certain altitude, after active side template and anode block disengage, the active side template resets rapidly under the effect of gravity off-centre own, fit tightly with the die sleeve base, the carbon piece that finishes is pushed out, because fixedly lower bolster is fixedly mounted on the make-up machine shake table, fluting template on it and chamfering template are parallel to the direction that anode block is released when installing, therefore the carbon piece is in push, with the fixedly lower bolster realization demoulding, after all mechanisms reset, begin the production of following one-period again.

The utility model does not need to increase in addition other actuating units to be carried out, simple in structure, easy to operate, good reliability.Can adapt to the carbon piece of producing all size, according to the specification of producing the carbon piece, change corresponding die sleeve, fluting template, chamfering template and active side template get final product.

The utility model can be accelerated the gas discharging that electrolysis produces along the bottom slot of anode block length direction, thereby reduces the bubble pressure drop of anode, reduce power consumption, improve anode effect, and increased anode surface and electrolytical contact area, thereby the increase cell reaction improves aluminium output; Chamfering is carried out in the utility model antianode carbon piece bottom, can reduce the carbon slag and alleviate the weight of monolithic anode, reduces monolithic anode inert weight, reduces the anode unit consumption, and is significant to energy-saving and emission-reduction, consumption reduction synergy work; The utility model fluting template is released direction along anode block constant slope, is convenient to the demoulding; The utility model does not need to increase in addition other actuating units to be carried out, simple in structure, easy to operate, good reliability.

The specific embodiment

Embodiment: earlier ear seat 3 is welded on die sleeve 1 bottom, with bearing pin that two active side templates 2 and ear seat 3 is hinged in die sleeve 1 bottom then, two active side template 2 symmetries are installed, and its center of gravity is eccentric; Again two fluting templates 5, two chamfering templates 6 and fixed base plate 7 are assembled into fixedly lower bolster 4, finish fixedly that lower bolster 4 usefulness bolting are installed on the make-up machine shake table, at last the die sleeve 1 that assembles is lifted on fixedly on the lower bolster 4 and the anode paste of packing into gets final product.Fluting template 5 and chamfering template 6 are parallel to each other each other, and are parallel to the direction that anode block 8 is released; Fluting template 5 vertical direction have pattern draft; Fluting template 5 is released direction along anode block 8 constant slope, and promptly a point is convenient to the demoulding than the high 10～20mm of b point.The utility model can be accelerated the gas discharging that electrolysis produces, thereby reduces the bubble pressure drop of anode, reduces power consumption, improves anode effect, thereby increases cell reaction, improves aluminium output; Chamfering is carried out in the utility model antianode carbon piece bottom, can reduce the carbon slag, also can alleviate the weight of monolithic anode, reduces monolithic anode inert weight, reduces the anode unit consumption.
