The inside of ladle 1 has seted up main inlet channel 103, and main inlet channel 103 realizes that gas collecting cavity 101 communicates with each other with intake pipe 4 tip cavity, and the one end of main inlet channel 103 is located the top of pressure boost bottom plate 8 to when pressure boost bottom plate 8 is in gas collecting cavity 101 bottommost, main inlet channel 103 communicates with each other with gas collecting cavity 101, and after pressure boost bottom plate 8 goes upward, can pass through pressure boost bottom plate 8 side and block up main inlet channel 103.
The end of the transposition push rod 10 is movably provided with a sealing air push block 11 positioned at one side of the air inlet pipe 4, the inner side of the ladle 1 is provided with a main air inlet groove 102 positioned between the sealing air push block 11 and the transposition push rod 10, a return spring 12 is also arranged between the sealing air push block 11 and the transposition push rod 10, one end of the return spring 12 is fixed at the inner side of the ladle 1, one end of a main air inlet channel 103 is positioned between the sealing air push block 11 and the transposition push rod 10, when the air inlet pipe 4 stops inputting argon, the sealing air push block 11 moves towards the air inlet pipe 4 by the elasticity of the return spring 12, and the cavity at the end of the air inlet pipe 4 and the cavity at the end of the return spring 12 are communicated by the sealing air push block 11.
When the device is used, in a normal state, the lock rod 140 is clamped in the cylindrical groove in the middle of the pressurizing bottom plate 8, when argon is input into the air inlet pipe 4, the air flow can push the air sealing push block 11, the reset spring 12 between the air sealing push block 11 and the transposition push rod 10 is compressed until the air flow is input from the main air inlet groove 102 to the main air inlet channel 103, so that the air flow is input into the air collecting cavity 101, and when the air flow pressure is increased, the air flow is output from the air brick 5, the movable brick 3 is jacked up, and then the device works according to the content in the second embodiment.
When the air inlet pipe 4 stops delivering air, the air sealing pushing block 11 is elastically far away from the main air inlet groove 102, and seals the air inlet pipe 4 and the cavity at the end part of the transposition pushing rod 10, if at the moment, the two movable bricks 3 are sealed with the inner side of the air outlet groove 100, when the movable bricks 3 are downward, the air flow in the air outlet groove 100 is extruded until the air flow cannot be extruded, so that the movable bricks 3 cannot further descend, and molten steel cannot flow back into the air brick 5.
If the inner sides of the movable bricks 3 and the exhaust grooves 100 are not sealed, the two movable bricks 3 are different in speed when the movable bricks 3 are in descending due to leakage, when the movable bricks 3 are in height difference, the lower adjusting arm 7 is stretched out by the elasticity of the top spring 17, so that the arm support 16 is far away, the fixed magnetic blocks 18 are exposed, but the magnetism blocking head 160 still blocks half of the fixed magnetic blocks 18, the exposed fixed magnetic blocks 18 and the pressurizing magnetic blocks 13 generate a magnetic attraction phenomenon, the guide seat 9 is pulled by the pressurizing magnetic blocks 13, the higher movable bricks 3 are pulled downwards rapidly by the guide seat 9 through the adjusting arm 7, the air flow pressure in the air collecting cavity 101 is enhanced, molten steel is prevented from flowing back from a gap, and at the moment, the reset pipe 14 is in a relatively vertical state due to the locking rod 140 clamped in the cylindrical groove in the pressurizing bottom plate 8, and the pressurizing bottom plate 8 is limited to ascending.
The continuous descending guide seat 9 can enable the arm support 16 to be pressed at the end part of the reset tube 14, the magnetic blocking head 160 is opened along with continuous downward movement of the arm support 16, at the moment, the movable brick 3 is completely pressed on the surface of the air brick 5 to seal the top end surface of the air brick 5, argon air flow exists in the liquid sealing cavity 105, molten steel is prevented from flowing back into the air brick 5 through the air flow, meanwhile, after the magnetic blocking head 160 is far away from the avoidance groove, the fixed magnetic block 18 attracts the lock rod 140, the lock rod 140 is magnetically attracted upwards and separated from the cylindrical groove, and due to separation of the lock rod 140, the inclined surface in the middle of the pressurizing bottom plate 8 directly props up to the reset tube 14, so that the pressurizing bottom plate 8 is forced to further upwards, the reset tube 14 deflects by taking the hinge point of the fixed rod 15 and the reset tube 14 as an axis, and the reset tube 14 deflects towards the direction far away from the air inlet tube 4, but at the moment, the end part of the reset tube 14 cannot be separated from the arm support 16.
Along with the ascending of the pressurizing bottom plate 8, further air flow in the air collecting cavity 101 is compressed, because at the moment, both air bricks 5 are blocked by the movable bricks 3, when the movable bricks 3 completely seal the air bricks 5, the air flow pressure in the air collecting cavity 101 can be further increased, molten steel is prevented from overflowing into the air bricks 5, meanwhile, because the movable bricks 3 always block the air bricks 5, when the refractory bricks 2 are poured out, the movable bricks 3 are also always blocked, the phenomenon that part of molten steel flows back from the air bricks 5 when the refractory bricks 2 are poured out is avoided, and after the air bricks 5 and the movable bricks 3 are not completely sealed, the air flow extruded in the air collecting cavity 101 can be released into the liquid sealing cavity 105, so that the air flow pressure and the air flow in the liquid sealing cavity 105 are enhanced, the air flow is further prevented from overflowing into the end part of the air bricks 5 from the liquid sealing cavity 105, and the molten steel backflow is more effectively prevented.
Finally, when the air inlet pipe 4 is inflated again, the air sealing pushing block 11 is pushed to move first, because the main air inlet channel 103 is sealed by the ascending pressurizing bottom plate 8 at this time, the air flow can only push the transposition push rod 10, along with the pushing of the end of the transposition push rod 10, the end part of the reset pipe 14 can be far away from the arm support 16, at this time, the transposition push rod 10 pushes the reset pipe 14 to be far away from the arm support 16 as a labor-saving lever, the reset pipe 14 and the arm support 16 are easier to separate, the continuously pushed transposition push rod 10 can move to the position of the reset air groove 104, at this time, the air flow can be directly input into the air collecting cavity 101, the air flow flowing outwards from the air permeable bricks 5 can be forced due to the continuously increased air flow pressure in the air collecting cavity 101, finally, the two movable bricks 3 can be upwards moved upwards, the ascending movable bricks 3 can enable the arm support 16 to move relatively again until the fixed magnetic block 18 is blocked by the arm support 16, and after the pressurizing magnetic block 13 is no longer magnetically sucked with the fixed magnetic block 18, the pressurizing bottom plate 8 is subject to gravity descending until the pressurizing bottom plate 8 moves to the bottom of the air collecting cavity 101, the main air inlet channel 103 is opened, at this time, the opened main air inlet channel 103 can lead the air flow pressure at two sides of the transposition push rod 10 to be communicated, the transposition push rod 10 is also subject to the influence of the elasticity of the reset spring 12, further, the transposition push rod 10 moves away from the reset air groove 104 in a direction away from the reset air groove 104, the transposition push rod 10 is completely away from the reset air groove 104, so that the air flow only enters through the main air inlet channel 103, at the same time, the moving transposition push rod 10 can pull the reset pipe 14 to be vertical, the lock rod 140 can be subject to gravity descending until the lock rod 140 is clamped into the cylindrical groove in the pressurizing bottom plate 8 again, when the air inlet pipe 4 stops the air flow input, the air sealing push block 11 is ejected by the elasticity of the reset spring 12, thus the cavities at the ends of the air inlet pipe 4 and the transposition push rod 10 are cut off, after that, the air intake pipe 4, which stops supplying air, operates as described above.
In the third embodiment, when the movable brick 3 leaks in a gap, the guide seat 9 is forced to descend by using the magnetic attraction of the pressurizing magnetic block 13 and the fixed magnetic block 18, the movable brick 3 is kept to be always tightly attached to the air brick 5 under the magnetic repulsion between the pressurizing magnetic block 13 and the fixed magnetic block 18, so that molten steel is further prevented from flowing back from the air brick 5, on the basis, the pressurizing bottom plate 8 is used for pressurizing air flow in the air collection cavity 101, the internal pressure in the air collection cavity 101 is maintained, and the argon air flow pressure in the liquid sealing cavity 105 is further enhanced under the condition that the air brick 5 and the movable brick 3 are not tightly sealed, so that the molten steel is fundamentally prevented from flowing back.
