Description
Technical field
The utility model belongs to aluminium electrolytic cell short-circuit port insulation technology field, especially a kind of pre-calcining electrolytic cell short-circuit opening
Insulated isolated device.
Background technology
In current electrolysis aluminium industry, to the insulation board that the insulation protection of short-circuit opening is generally slotted using two pieces of middle parts, to hand over
The mode of fork covering is overlapped installation, and carrying out open circuit with the electrolysis of riser bus bar to short-circuit block is isolated, and passes through stud
It is passed through from the slot of insulation protective board with insulating sleeve, short-circuit block is fixed on to the both sides of riser bus bar.With aluminium electroloysis groove profile
Enlargement, the insulating Design of short-circuit opening still continues to use same allocation plan always, on high current produced in series line, short-circuit opening
In the presence of very big breakdown risk.
In actual production, due to the dust accumulation and impurity at the aging of insulating sleeve, carbonization and insulation board fluting, cause
There are great security risks for this insulation protection.Fluting gap at two layers of insulation board crimping there are larger ionization risk,
Short-circuit opening breakdown, which is blown out, can cause great production safety hidden danger, and the short time is not easy to restore, and can cause serial halt production accident,
Cause great economic loss and security loss.
Utility model content
In order to solve the above technical problems, a kind of pre-calcining electrolytic cell short-circuit opening of the utility model offer is dielectrically separated from dress
It puts, including short-circuit block, riser bus bar, insulation board, insulating suspension device, the insulation board is between riser bus bar and short-circuit block
Gap in, short-circuit block is fixed on the both sides of riser bus bar by the insulating suspension device.
The insulating suspension device includes insulation platform sling, insulated column, insulation nut, stud, and insulation platform sling is one piece
Inequilateral insulation board, bevel edge is upward, and surrounding is provided with 4 mounting holes, and stud is connected to riser bus bar both the above mounting hole
Between insulation platform sling, junction is fixed using insulation nut；Insulated column one end be equipped with screw thread, short-circuit block be equipped with
The hole that insulated column matches, one end of without screw thread are located in the hole of short-circuit block, and one end that insulated column has screw thread is pacified by the nut that insulate
On the lower opening position of insulation platform sling.
The insulated isolated device of the utility model pre-calcining electrolytic cell short-circuit opening realizes and the complete of short-circuit opening electrolysis is covered
Lid protection.
The utility model short circuit port insulation protective device fixes short-circuit block, using the insulation of no slot using erecting by overhang
Plate carries out breaking isolation；The trepanning on riser bus bar assigns stud to accept erecting by overhang for fixing short-circuit block, using nothing
The insulation board of slot carries out breaking isolation；Short-circuit opening electrolysis insulation board without slot, electrolysis to short-circuit block and three it is adjacent
Face carries out all standing protection；Short-circuit block is fixed using insulation platform sling, the Bolt sizes of column interface installation platform sling add
It is long, the suspension hanger as insulation platform sling.
It is the utility model is designed reasonably, easy to implement, it is anti-to realize the insulation of all standing to short circuit mouth for electrolytic bath electrolysis
Shield, completely eliminates the hidden danger of breakdown sparking, while does not influence the operation of short-circuit opening and the installation of uninterruptive switching, to daily
Change poles and upkeep operation do not form interference.
