Abstract

The utility model discloses a novel insulator arrangement of aluminium cell, including thick insulation board, the preparation has four T type bolt holes on the insulation board, four T type bolt holes divide two kinds from top to bottom, one kind be (img file='DSA0000116755360000011. TIF'wi='43'he='34' /) type bolt hole down, one kind be (img file='DSA0000116755360000012. TIF'wi='49'he='36' /) type bolt hole up, install four bolts in the bolt hole, article four, the bolt is installed according to T type bolt hole orientation, two bolts of every orientation respectively install thin insulation board additional, the size is the same with thick insulation, bolt hole on the insulation board is corresponding with bolt size distance, aluminum -plastic laminated tube and electric conductor contact are kept apart in the effect of these two thin insulation boards. The one set of electric conductor that can fix both sides is formed like this, novel insulator arrangement insulating completely can be realized again. Single insulation system before the novel insulator arrangement of this cover has been avoided has improved insulating grade, has prolonged insulating material's life, has avoided the emergence of accidents such as electric leakage, electric shock, brings great safety and economic benefits for enterprise and society.

Description

A kind of aluminum electrolysis bath novel seal

Technical field

The utility model belongs to aluminum smelting technology technical field, is specifically related to a kind of aluminum electrolysis bath novel seal

Background technology

In aluminum smelting technology industry, aluminium cell production is the maximum device of consumes power, electrolyzer electric installation converts electric energy to the heat energy of about 960 DEG C by the solution in groove, the aluminum oxide powder fusing that solute in electrolyzer will enter in solution through about 960 DEG C high temperature, form electrochemistry reflection and generate electrolytic aluminium liquid, then carry out refining by vaccum bench bag sucking-off aluminium liquid and be processed into aluminium ingot or aluminium product is sold.

1 ton of aluminium often produced by aluminium cell needs to consume Integrated Exchange power consumption about 13800kw.h/tAl.The electrolytic cell equipment of high temperature, high power consumption is very high to the requirement of insulation level, although aluminium cell insulating Design is no less than 3 grades, the insulation of every grade is also different according to the design of position different insulative.The insulation of electrolyzer is through the electrolysis production in a period, its insulation level declines or is destroyed, the most destroyed position is the insulcrete between the iron angle of load style plate and electrolytic bath shell support, and the reason of damage mainly contains three aspects: 1, insulcrete is in the hot environment of more than 100 DEG C for a long time.2, the electrolyzer face-piece deblocking temperature that electrolysis workman pulls out from electrolyte solution when change poles is up to about 900 DEG C, drop on equitemperature on style plate to seal pole workman after cooling down and just face-piece block is transported by handling appliance, larger to the destruction of insulation of surrounding during the high temperature cooling of face-piece block.3, due to electrolysis workman change poles, Feng Ji, arranging between the working lifes such as boiler face drops between style plate by the fabric block of part, ventilate for keeping style plate, environmental health is clean, field worker often finishes a job all will start the fabric between cleaning by style plate, often starting the insulcrete of a style plate to angle bar bottom is exactly once vibrate, time one length is clipped in insulcrete inner bolt insulating mat between angle bar and pot shell and can be destroyed, cause short circuit between style plate and electrolytic bath shell, owing to there is no insulating material between style plate and angle bar, style plate becomes the conductor between two electrolyzers, cause a large amount of waste of energy, cause the security threat of electric shock can to time serious execute-in-place employee.

Insulcrete between the iron angle of China's aluminium cell load style plate and electrolytic bath shell support has also existed very large defect (Fig. 2) since designing, the insulcrete of this structure is easy to be reduced insulation level and destruction by above three kinds of situations, causes waste of energy and personnel safety.

Utility model content

The purpose of this utility model is to overcome prior art defect, provides a kind of aluminum electrolysis bath novel seal.

Based on above-mentioned purpose, the utility model takes following technical scheme:

A kind of aluminum electrolysis bath novel seal, comprise one piece of thicker insulcrete, insulcrete is manufactured with four Xia type bolt holes, four Xia type bolt holes divide upper and lower two kinds, one be Xia type bolt hole down, one be mo(u)ld top half bolt hole up, four bolts are installed in bolt hole, four bolts are according to installing according to Xia type bolt hole direction, two bolts in each direction respectively install one piece of thinner insulcrete additional, size is identical with thicker insulation, bolt hole on insulcrete is corresponding with the large small distance of bolt, the effect of these two blocks of thin insulating plates is isolation nuts and conductive body contact.The a set of electrical conductor can fixing both sides of such formation, can realize again the New insulated device (Fig. 1) insulated completely.

The utility model has the advantage of: insulation system single before this cover New insulated device avoids, achieve the insulation isolation of both sides electrical conductor, improve the grade of insulation, extend the work-ing life of insulating material, avoid the generation of the accidents such as electric leakage, electric shock, bring larger safety and economic benefit to enterprise and society.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is intrinsic structural representation;

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details, but protection domain of the present utility model is not limited thereto.

As shown in Figure 1, a kind of aluminum electrolysis bath novel seal of the utility model, comprise thicker insulcrete 10 above according to the position of electrical conductor bolt hole, be manufactured with four Xia type bolt holes 13, 14, four Xia type bolt holes divide upper and lower two kinds, one is Xia type bolt hole down 1, 4, one is mo(u)ld top half bolt hole up 2, 3, four bolts 1 are installed in bolt hole, 2, 3, 4, four bolts are according to installing according to Xia type bolt hole direction, two bolts in each direction respectively install one piece of thinner insulcrete 8 additional, 11, size is identical with thicker insulation 10, bolt hole on thin insulating plate will with the large small distance of bolt corresponding 9, bolt head uses hexagon socket head cap screw 12, bolt head enters in insulcrete bolt hole and can not highlight, bolt head will be absorbed in 1-2mm in insulation and be convenient to thin insulating isolating seal 5, install a plain cushion and spring pad 7 between nut with thin insulating plate additional to be convenient to electrical conductor and to crimp well, it is firm that nut uses hexagonal (hexagon)nut 6 to be convenient to spanner.

During use, four bolts 1,2,3,4 are installed according to the Xia type bolt hole direction in face on insulcrete 10 respectively, after the more corresponding bolt of thin insulating plate 8,11 being installed, put into need insulation object in the middle of, bolt of having gone here and there installs plain cushion and compression spring, tighten hexagonal (hexagon)nut, realize the insulation of electrical conductor.

Finally illustrate: above-mentioned enforcement is only illustrative rather than definitive thereof the technical solution of the utility model; any equivalent replacement of carrying out the utility model and the amendment not departing from the utility model spirit and scope or local are replaced, and it all should be encompassed within the scope of the utility model claim protection.
