Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As shown in Figures 1 and 2, a kind of sealed dust-removing device for LF stove electrodes, including source of the gas connecting tube 1, manual ball
Valve 2, compression ring connecting tube 9, seal gas ring 10 and bell 12, source of the gas connecting tube 1 are connected with air supply source, and manual ball valve 2 connects gas
Source connecting tube 1, compression ring connecting tube 9 connect manual ball valve 2, and seal gas ring 10 connects compression ring connecting tube 9；10 internal diameter of seal gas ring
Equipped with stomata 101, bell 12 is equipped with electrode hole 121, and seal gas ring 10 is arranged on electrode hole 121.
The stomata 101 is multiple, is evenly arranged on the internal diameter of seal gas ring 10.During specific arrangement, between stomata 101
20-40mm can be spaced, it is too small that the spacing of stomata 101 crosses the air curtain intensity that conference results in, and can not complete to the close of dust
Envelope, if what is set is too small, it is excessive to be easy to cause air curtain intensity, increases LF furnace pressures, forms security risk.
The stomata 101 and level are in 5-45 ° of angle downwards.During specific arrangement, stomata can be selected according to specific circumstances
101 angles tilted down, stomata 101 tilt down, and can apply downward power to dust by air-flow, make it into dedusting
Pipeline.This angle is set too small, then the pressure applied to dust is too small, easily leads to the effusion of dust, can not complete to seal, if
What is set is excessive, then air curtain cavity can be formed in the center section of seal gas ring 10, causes dust to escape, can not complete to seal.
Point gas bag 7 is further included, divides 7 one end of gas bag to connect manual ball valve 2, other end connection compression ring connecting tube 9, works as blanket gas
Ring 10 carries out a point gas when being multiple to gas.The electrode of LF stoves is 3 under normal circumstances, when use need to 3 electrodes all into
Row sealing, so needing to carry out a point gas to the air-flow for being connected to 3 seal gas rings 10, sets divide gas bag 7 herein, it is possible to achieve
The steady of air-flow is controlled and evenly distributed, is prevented between each seal gas ring 10 because being sealed caused by air pressure difference uneven
It is even.
Manual needle valve 8 is further included, manual 8 one end of needle valve connection divides gas bag 7, other end connection compression ring connecting tube 9.It is logical
Cross before each seal gas ring 10 and manual needle valve 8 is set, it is possible to achieve the air-flow of each seal gas ring 10 is opened and closed
Operation, so that the preferably operation of control device.
Further include Self-operated pressure reducing valve 3, pressure gauge 4, pneumatic ball valve 5 and pneumatic control valve 6, Self-operated pressure reducing valve 3 one
End connection manual ball valve 2, other end connection pressure gauge 4, pressure gauge 4 connect pneumatic ball valve 5, and pneumatic ball valve 5 connects pneumatic adjusting
Valve 6, the connection of pneumatic control valve 6 divide gas bag 7.
, can by setting various control valve to carry out many control to the air-flow in pipeline during being flowed in source of the gas
To realize the adjusting of manifold pressure.Pressure gauge 4 can in real time at reflection in pipeline pressure, for operating personnel provide operation ginseng
Examine, when insufficient pressure or it is excessive when can close corresponding valve in time, avoid the appearance of accident.Pneumatic ball valve 5 is adjusted with pneumatic
Valve 6 in real time can be controlled the pressure in pipeline, pass through its adjusting to manifold pressure, it is possible to achieve air-flow it is steady
Output, beneficial to the good operation that device is overall.
Further include the manual needle valve 11 of bypass, bypass manual needle valve 11 one end cut-in pressure table 4 and pneumatic ball valve 5 it
Between, the other end accesses pneumatic control valve 6 and divides between gas bag 7.
Manual needle valve 11 is bypassed by setting, whole device can be made to realize manual control in Pneumatic pipe, in gas
Dynamic ball valve 5 or pneumatic control valve 6 do not influence to use when breaking down.
The compression ring connecting tube 9 is metal hose.
Inert gas is generally used as shape according to live actual arrangement pipeline, installation valve, source of the gas by attached drawing during implementation
Into the gas of air curtain, argon gas is selected here as source of the gas.When making seal gas ring 10, stomata 101 is horizontal by downward 5
~45 degree of angles, are preferably 10-30 degree angle, and concrete condition circular hole is preferably 30-40mm at intervals of 20~50mm.Connected in compression ring
Connected when pipe 9 is connected with manual needle valve 8 using nylon connector, seal gas ring 10 is fixed on bell 12 after connection
On.
The air curtain closure dust that the utility model is formed using gas injection is in water cooled cover, then by original dedusting system
