Description
Technical field
The utility model is related to a kind of joint structures more particularly to a kind of electric furnace insulation trombone slide connector to connect sealing structure.
Belong to metallurgical machinery equipment technical field.
Background technology
Insulation trombone slide is mounted in copper-steel composite plate, a weight in the coordination electrode clamper on water cooling conductive cross arm tail portion
Building block is wanted, mainly by transmitting fluid, disc spring clamping holder is opened to realize, hydraulic cylinder is made to have loosened paired electrode tune
It is whole；For this purpose, insulation trombone slide connector is also during entire production is smelted, it is necessary to assure insulate with electrode clamping sebific duct junction, really
Ensure safety operation, meets production requirement.
My subsidiary factory is the HX-30t high Impedance Electric Arc Furnaces used, mainly by 3 sets of stand column device, conductive cross arm, rotating device,
The compositions such as upper lower furnace body；Electrode folds up device and is placed in conductive cross arm, is rear-mounted, outer connection insulating joint is mounted on transformer
Exterior wall (former connector is designed as bakelite) is made moist using rear bakelite for a period of time causes insulated part deformation, gasket leakage, internal
There is arcing, sebific duct or insulated tension pole arcing failure occur, needs timely blowing out to solve, shadow is caused to the normal quantity-produced of electric furnace
It rings and hydraulic station fuel tank fluid is contaminated, processing not in time can cause other equipment failure, oil pump damage, electric-hydraulic proportion
Valve is failure to actuate, and electric furnace cannot return the big packet that inclines and overflow molten steel etc. when tapping.Circulating filtration pollutant need to be beaten again；Solve connector arcing also
Furnace roof operation at high temperature, high-altitude need to be gone up, there are larger security risks.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electric furnace insulation trombone slide for the above-mentioned prior art to connect
Head connection sealing structure, it is ensured that equipment safety, reliable, normal operation, to produce demand creation condition.
The technical scheme in the invention for solving the above technical problem is：A kind of electric furnace insulation trombone slide connector connection sealing
Structure, it includes being arranged to thoroughly do away with the insulation inner sleeve between edge trombone slide end two, and the insulation inner sleeve inner hollow forms oil
Road is provided with connector sleeve, by O-shaped between insulation inner sleeve and the connector sleeve on the both sides insulation trombone slide of the insulation inner sleeve
Circle sealing, insulating spacer is respectively arranged on the outside of the connector sleeve that two are arranged symmetrically, and is distinguished in the outside of the insulating spacer
It is provided with case and end cap, the case and end cap incomplete contact between, and is locked or is dismantled by bolt.
Preferably, the internal oil passages aperture of the insulation inner sleeve is 20mm.
Preferably, the insulation inner sleeve is made of polyimides.
Preferably, the connector sleeve, case and end cap are made of carbon steel material.
Compared with prior art, the utility model has the advantage of：
(1) external structure is simple, carries, dismounting is also convenient for and can complete to dismount in 15 minutes.
(2) ensure No leakage during transmitting fluid, unclamp clamper, complete electrode and exchange.
(3) insulation effect is good in normally smelting transmission process, is not in energization, phenomenon of arc discharge, it is ensured that safety in production.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Wherein：Insulate trombone slide 1, insulation inner sleeve 2, connector sleeve 3, insulating spacer 4, case 5, end cap 6, bolt 7.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
Referring to Fig. 1, a kind of electric furnace insulation trombone slide connector of the utility model connects sealing structure, including setting is thoroughly done away with two
Insulation inner sleeve 2 between 1 end of edge trombone slide, the insulation inner sleeve 2 are made of polyimides, inner hollow, aperture 20mm,
Oil circuit is formed, connector sleeve 3 is provided on the both sides insulation trombone slide 1 of the insulation inner sleeve 2, the connector sleeve 3 is made of carbon steel,
It is sealed by fluororubber O-type ring 4 between the insulation inner sleeve 2 and connector sleeve 3, prevents the interior leakage of fluid, in two symmetrical cloth
The outside of connector sleeve 3 set is respectively arranged with insulating spacer 4 made of epoxy resin, and there are certain between two insulating spacers 4
Gap, do not contact, case 5 and end cap 6 made of carbon steel, the cover be respectively arranged in the outside of the insulating spacer 4
6 incomplete contact between of shell 5 and end cap, and locked or dismantled by bolt 7, it is convenient and efficient.
The foregoing is merely a kind of preferable implementations of the utility model, are not intended to limit the utility model,
All non-essential modification, replacement, improvement etc. made in the utility model spirit, should be included in the utility model
Within protection domain.
