Abstract
The utility model relates to a kind of sealing devices, including ash releasing tube (4), it is characterized by: the device is equipped with hydraulic cylinder (1), the telescopic rod of hydraulic cylinder (1) is connect using the first pin shaft (9) with pull rod bracket (3), pull rod bracket (3) is fixedly connected using the second pin shaft (10) with fixed device (11), fixed device (11) are fixed on ash releasing tube (4), pull rod bracket (3) lower end fixing seal cover board (2), fixing seal pad (6) on seal cover board (2), the nozzle (8) of the ash releasing tube (4) installs ash releasing tube mouth additional outside widens sealing ring (5), ash discharge nozzle widens the surface of sealing ring (5) and nozzle (8) in one plane, increase the contact surface with gasket (6).The utility model improves the energy efficiency that VD furnace is vacuum-treated operation；The more effective hydrogen content degree reduced in vacuum processing of liquid steel；Replacement cost and the hand labor for reducing sealer gun and rifle line are strong.
Description
Technical field
The utility model belongs to Ferrous Metallurgy steelmaking technical field more particularly to a kind of sealing device.
Background technique
In Ferrous Metallurgy, if the hydrogen content being dissolved in molten steel is higher, steel product stress concentration will cause, more than the pole of steel
Intensity is limited, tiny crackle, also known as white point is formed inside steel, seriously affects the quality of steel.In order to mitigate the hydrogen in molten steel
Influence of the content to the performance of steel performance, positive reciprocal of duty cycle controls the hydrogen content key reduced in molten steel and makees in VD smelting process
With.Extremely incendive combustible dust (CaO, MgO) is stored in cleaning shaft at present, is easy to burn the gasket in sealing
Deformation, caused sealing device contact area is small to be easy to cause poor sealing, influences the positive reciprocal of duty cycle of VD furnace operation process, influences positive sky
Deaeration capacity under operation, by manually sealing gasket.
Summary of the invention
The utility model against the above deficiency place, a kind of sealing device is provided, gasket stability contorting is realized, improve
VD furnace is vacuum-treated the energy efficiency of operation.Realizing technical solution adopted in the utility model is: a kind of sealing device, including
Ash releasing tube, it is characterised in that: the device is equipped with hydraulic cylinder, and the telescopic rod of hydraulic cylinder is connect using the first pin shaft with pull rod bracket,
Pull rod bracket is fixedly connected using the second pin shaft with fixed device, and fixed device is fixed on ash releasing tube, and pull rod pedestal lower end is solid
Determine seal cover board, fixing seal pad on seal cover board, the gasket is fixed on seal cover board with fixing bolt；Described
It installs ash releasing tube mouth outside the nozzle of ash releasing tube additional and widens sealing ring, ash discharge nozzle widens the surface of sealing ring and nozzle in a plane
On, increase the contact surface with gasket.
The utility model realizes gasket stability contorting, improves the energy efficiency that VD furnace is vacuum-treated operation；More effectively
Reduce the hydrogen content degree in vacuum processing of liquid steel；Replacement cost and the hand labor for reducing sealer gun and rifle line are strong, using fast
It is prompt, safe and reliable；Design and produce simple easy, low manufacture cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram that ash discharge nozzle widens sealing ring in the utility model.
Fig. 3 is the structural schematic diagram of seal cover board in the utility model.
In figure, 1-hydraulic cylinder；2-seal cover boards；3-pull rod brackets；4-ash releasing tubes；5-ash discharge nozzles widen sealing
Ring；6-gaskets, 7-fixing bolts, 8-nozzles, the 9-the first pin shaft, the 10-the second pin shaft, 11-fixed devices.
Specific embodiment
Referring to attached drawing, a kind of sealing device, including ash releasing tube 4, it is characterised in that: the device is equipped with hydraulic cylinder 1, hydraulic cylinder
1 telescopic rod is connect using the first pin shaft 9 with pull rod bracket 3, and pull rod bracket 3 is fixed using the second pin shaft 10 and fixed device 11
Connection, fixed device 11 are fixed on ash releasing tube 4,3 lower end fixing seal cover board 2 of pull rod bracket, fixing seal on seal cover board 2
Pad 6, the gasket 6 are fixed on seal cover board 2 with fixing bolt 7；Install ash discharge outside the nozzle 8 of the ash releasing tube 4 additional
Nozzle widens sealing ring 5, and ash discharge nozzle widens the surface of sealing ring 5 and nozzle 8 in one plane, increases and gasket 6
Contact surface.
The utility model mainly increases VD boiler tube road airtightness, it is ensured that the vacuum degree under working condition, gasket are fixed on
On cover board (detachable), cover board is connected on hydraulic cylinder, and seal cover board and ash discharge critical point can carry out 120 degree of rotations, ash releasing tube
Mouth is widened sealing ring 5 and is made by steel material.The utility model realizes ash discharge operation stability contorting, improves positive vacancy reason and makees
The validity of industry reduces gasket replacement cost, labor intensity and the safety of operating personnel, using it is quick, safe,
Reliably.
The course of work of the utility model is as follows,
After VD furnace exhausts vacuum every time breaks empty, using solenoid valve control pneumatic operated valve, pneumatic operated valve controls hydraulic cylinder by linking
Device carries out cover board opening to put grey operation, puts the automatic closure flap of hydraulic cylinder after grey operation is completed 15 seconds and covers.
