The sealing of bell avoids occurring gap between bell and electrode.
To solve above-mentioned technical problem the technical scheme adopted by the invention is that: blast furnace slag mention titanium carbide furnace electrode sealing dress
It sets, including electrode and bell, the sealing device is made of the sealant, flame retardant coating and water-cooled layer set gradually from inside to outside,
The sealant is connect with bell, and flame retardant coating is equipped at least one locking device.
Further, the edge flange of the sealant and with the outer surface of sealant formed seal chamber, the sealing
It is intracavitary to be equipped with sealing ring.
Further, the sealing ring is elastic seal ring.
Further, being equipped with mobilizable refractory brick in the flame retardant coating, the refractory brick is leaned on electrode paste.
Further, the locking device quantity is four and is uniformly arranged on surrounding them.
Further, the locking device is made of locking spring and clamping screw, the both ends of clamping screw respectively with
Refractory brick and locking spring connection.
Further, being equipped at least two layers of sealing cavity in the water-cooled layer, water-supply-pipe is connected in the sealing cavity
Road.
Further, the sealing cavity interval is arranged, packing material is equipped between adjacent seals cavity.
Further, the packing material is the asbestos for being arranged around electrode and wrapping up electrode.
Further, being tightly connected between the sealant, flame retardant coating and water-cooled layer by bolt lock.
Beneficial effects of the present invention are as follows:
(1) it realizes and bell is fully sealed, can effectively prevent in furnace body that flue gas is excessive, improve production environment；
(2) electrode can be adjusted, electrode is avoided to be displaced because of lifting；
(3) it effectively prevents occurring gap between electrode and furnace body, flue gas can be prevented to enter in gap, electrode is caused to disappear
Consumption；
(4) it ensure that furnace heat will not be excessive in production, reduces the loss of furnace heat, improve the work effect of electric furnace
Rate.
Detailed description of the invention
Fig. 1 is structure sectional view of the invention；
In the figure, it is marked as 1- electrode, 2- bell, 3- sealant, 31- seal chamber, 32- sealing ring, 4- flame retardant coating, 41- are resistance to
Firebrick, 42- locking spring, 43- clamping screw, 5- water-cooled layer, 51- aqueduct, 52- packing material.
Specific embodiment
To facilitate the understanding of the present invention, the present invention is further detailed with reference to the accompanying drawing.
As shown in Figure 1, blast furnace slag of the present invention mentions titanium carbide furnace electrode seals, pass through the bell 2 in electric furnace
Upper setting sealing device realizes the sealing to bell 2, and sealing device is made of sealant 3, flame retardant coating 4 and water-cooled layer 5, sealing
Layer 3 is connect with bell 2, and flame retardant coating 4 is connect with sealant 3, and water-cooled layer 5 is connect with flame retardant coating 4, passes through bolt between each layer structure
Locking connection；Electrode 1 sequentially passes through sealant 3, flame retardant coating 4 and water-cooled layer 5, and locking device is equipped on flame retardant coating 4.
It is sealed against that only flue gas is excessive to bell 2 by sealant 3 in the present invention, is arranged in the edge of sealant 3
Flange, flange direction and the outer surface of bell 2 are perpendicular, and sealing is formed between the flange of sealant 3 and the outer surface of sealant 3
Junction between sealant 3 and bell 2 is isolated from the outside world by seal chamber 31, and is provided in seal chamber 31 by chamber 31
Sealing ring 32, sealing ring 32 use contractile elastic seal ring, reinforce the sealing to junction between sealant 3 and bell 2
Effect.
If can cause to wash away to electrode 1 in uphill process since flue gas is excessive, cause the loss of electrode 1, the present invention is logical
Setting flame retardant coating 4 is crossed to avoid the loss of electrode 1, as shown in Figure 1, refractory brick 41 is equipped in flame retardant coating 4, refractory brick 41 and electricity
Pole 1 reclines.When electric furnace works, 1 oscilaltion of electrode may be displaced, and cause gap occur between electrode 1 and refractory brick 41,
Therefore refractory brick 41 is movably arranged in flame retardant coating 4, and locking device is set on flame retardant coating 4 and comes the position to refractory brick 41
It is adjusted, is rectified a deviation by the movement of refractory brick 41 to electrode 1.Locking device is by locking spring 42 and 43 groups of clamping screw
At one end of locking spring 42 is connected on refractory brick 41, and the other end is then connect with clamping screw 43, is equipped on flame retardant coating 4
The fixed structure being threadedly engaged with clamping screw 43 adjusts the position of refractory brick 41 by turning clamping screw 43, finally makes
Electrode 1 returns back to original position in the horizontal direction.In order to realize to the uniform force in 1 horizontal direction of electrode, locked in the present invention
Device quantity is four and is uniformly arranged on around electrode 2.
The top of sealing device is arranged in water-cooled layer 5, and sealing cavity is equipped in water-cooled layer 5, and setting is cold in sealing cavity
But water, cooling water is by 51 circulation conveying of aqueduct that is connected to sealing cavity；Sealing cavity minimum number is simultaneously upper and lower two layers
Interval setting is packing material 52 between neighbouring sealing cavity, by packing material 52 fill water-cooled layer 5 and electrode 1 it
Between gap, packing material 52 is using asbestos commonly used by sealing in the industry in the present invention.
