Description

Technical Field

[0001] The invention relates to the technical field of burn-through of a submerged arc furnace door, and in particular to a novel reciprocating submerged arc furnace burn-through device. Background Art

[0002] At present, after the traditional submerged arc furnace is smelted, a burner is needed to open the furnace mouth so that the molten metal can flow out. The submerged arc furnace burner is also called an arc burner. Figure 1 As shown, it mainly consists of a carbon rod 1 (also called a small electrode), a handle 2 and a conductive component 3. The handle is suspended by a hanging structure 4 and can be moved and turned at multiple angles. The front end of the handle is inserted with the carbon rod through a holder 5 (sleeve structure). The conductive components include a cable 3.1, a "7"-shaped contact 3.2 and a ring-shaped copper busbar 3.3. The ring-shaped copper busbar supplies power to the carbon rod on the handle through fixed contacts and cables. When in use, a worker needs to hold the handle (wearing insulating gloves) to push the burner, bring the front end of the carbon rod close to the furnace mouth, and use the arc heat generated by the front end of the carbon rod to melt the mud ball at the furnace mouth to complete the opening of the furnace mouth.

[0003] During use, the burner needs to be manually controlled by the handle of the burner, and the carbon rod of the burner needs to be manually pushed to move. The current is introduced into the furnace eye through the carbon rod, generating high temperature to achieve the purpose of conducting the furnace mouth. In this working process, it is very dependent on manual operation, and the temperature around the furnace body is high. The staff also needs to push the burner under high temperature radiation and a large amount of smoke and dust gas. There are problems such as harsh working environment, high labor intensity, and difficulty in ensuring safety and health. Summary of the Invention

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1 like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a new type of reciprocating submerged arc furnace burner includes a gun body 6, a holder 5, an annular guide groove 7, a support frame 14, a rotating frame 8, a motor 11, a drive rod 12, and a slider 13. The holder 5 is fixed to the bottom of one end of the gun body 6, and the holder 5 is used to tightly insert and connect the carbon rod 1. The other end of the gun body 6 is fixed to a downwardly inclined annular guide groove 7.

[0030] A rotating frame 8 is provided on one side below the annular guide groove 7 for driving the gun body 6 to rotate horizontally. The rotating frame 8 includes a vertical rod 9 and a base 10. The top of the vertical rod 9 is the top of the rotating frame 8, and the bottom of the vertical rod 9 is connected to the base 10 for horizontal rotation; a motor 11 is fixed to one side of the top of the rotating frame 8. The motor 11 can adopt a variable frequency motor to facilitate speed control. The output shaft of the motor 11 passes through the rotating frame 8 and is fixed to one end of the driving rod 12. The other end of the driving rod 12 is rotatably connected to a slider 13, and the slider 13 is slidably placed in the annular guide groove 7; the slider 13 is circular, and an annular groove 13.1 is circumferentially provided along the outer edge of the slider 13, and the annular groove 13.1 is sleeved on the inner side of the annular guide groove 7.

[0031] The output shaft of the motor 11 rotates to drive the driving rod 12 to rotate, and the driving rod 12 drives the slider 13 to rotate. Figure 5 As shown by the clockwise arrow, the slider 13 rotates clockwise, and the slider 13 slides in the annular guide groove 7 and drives the annular guide groove 7 to move horizontally. Figure 5 As shown by the horizontal left arrow, it can move left. Affected by the rotation direction of the slider 13, the annular guide groove 7 drives the gun body 6 to move back and forth horizontally, so that the carbon rod 1 is guided to the furnace door after being heated; the annular groove 13.1 on the outside of the slider 13 is stuck on the inside of the annular guide groove 7 and is not easy to fall out. At the same time, the rotating frame 8 realizes the rotation function on the base 10 through the vertical rod 9, and uses the motor 11, drive rod 12, slider 13, and annular guide groove 7 to support the horizontal rotation of the gun body 6. The gun body 6 can be moved away from the furnace door direction without hindering the discharge of materials.

[0032] A support frame 14 is provided below the gun body 6 for supporting the gun body 6 to move back and forth horizontally and to rotate horizontally. A moving mechanism 15 is fixed to the bottom of the support frame 14. The moving mechanism 15 is a universal wheel with a locking structure. When the gun body 6 rotates horizontally, the universal wheel rolls, and the support frame 14 moves with the gun body 6. The top of the support frame 14 slides through the gun body 6. When the gun body 6 moves back and forth horizontally, the universal wheel is locked and does not move, and the gun body 6 moves on the support frame 14. The support frame 14 may be dragged by the gun body 6 and move a small distance, but it mainly serves to support the gun body 6 to maintain a horizontal moving posture.

[0033] A disc 16 is fixed on the vertical rod 9, and a through hole 17 is provided on the disc 16. A blind hole 18 is provided on the base 10 corresponding to the through hole 17. Pins 19 are interactively inserted into the through hole 17 and the blind hole 18. When the gun body 6 moves horizontally back and forth to dredge the furnace door, the through hole 17 on the disc 16 corresponds to the blind hole 18, and the pin 19 is inserted between the through hole 17 and the blind hole 18 to lock the disc 16, and the rotating frame 8 does not rotate, thereby avoiding rotation of the gun body 6 when it moves horizontally and stabilizing the horizontal movement posture of the gun body 6.

[0034] Working principle: When the furnace mouth is opened, the universal wheel is locked and does not move, and the support frame 14 supports the gun body 6, such as Figure 4 As shown, the annular copper row 3.3 of the conductive component supplies power to the carbon rod 1 on the gun body 6 through the fixed "J"-shaped contact 3.2 and the cable 3.1, and the output shaft of the motor 11 drives the driving rod 12 to rotate, and the driving rod 12 drives the slider 13 to slide in the annular guide groove 7 while driving the annular guide groove 7 to move horizontally. The annular guide groove 7 drives the gun body 6 to move horizontally, thereby realizing automatic guidance of the carbon rod 1 to the furnace door; when discharging or stopping the work, the universal wheel is unlocked, and the rotating frame 8 rotates on the base 10 through the vertical rod 9, and the motor 11, driving rod 12, slider 13, and annular guide groove 7 are used to support the horizontal rotation of the gun body 6, and the support frame 14 supports the gun body 6, and the gun body 6 can be moved away from the furnace door.

[0035] Example 2 like Figure 6 、 Figure 7 The above-mentioned novel reciprocating electric arc furnace burner has an overall structure similar to that of Example 1, except that an extension rod 20 is extended and fixed on the top of the rotating frame 8, an inclined support rod 21 is horizontally fixed on the top of the extension rod 20, and a sleeve 22 is fixed on the bottom of one end of the inclined support rod 21, and the sleeve 22 is sleeved on the gun body 6.

[0036] Working principle: The working principle is the same as that of Example 1, except that, when the furnace mouth is opened, the gun body 6 moves back and forth horizontally, and at the same time moves on the sleeve 22. The sleeve 22 is connected to the rotating frame 8 as a whole through the oblique support rod 21 and the extension rod 20, which plays a role in strengthening the support of the gun body 6 and strengthening the connectivity; when discharging or stopping, the rotating frame 8 rotates, not only using the motor 11, the drive rod 12, the slider 13, and the annular guide groove 7 to support the horizontal rotation of the gun body 6, but also relying on the extension rod 20, the oblique support rod 21, and the sleeve 22 to drive the gun body 6 to rotate, and the rotation is more stable.

[0037] Example 3 like Figure 8 、 Figure 9 、 Figure 10 and Figure 11 The invention relates to a novel reciprocating electric arc furnace burner, the overall structure of which is similar to that of Example 1 or 2, except that the moving mechanism 15 includes a fan-shaped track 23, a locking mechanism 24, and a roller 25. The roller 25 is rotatably connected to the bottom of the support frame 14, and the roller 25 is rolled on the fan-shaped track 23. The two ends of the fan-shaped track 23 are provided with a locking mechanism 24 for limiting the movement of the support frame 14.

[0038] The support frame 14 moves along the track curve on the fan-shaped track 23 through the roller 25, and drives the gun body 6 to move horizontally in conjunction with the rotation of the rotating frame 8 to achieve the purpose of making way; when the gun body 6 needs to move horizontally back and forth, the locking mechanism 24 limits the movement of the support frame 14, and the horizontal reciprocating movement of the gun body 6 is more stable, and the support frame 14 will not be dragged. Figure 2 、 Figure 6 、 Figure 8 The structure in the middle strengthens the counterweight of the bottom direction structure.

[0039] The locking mechanism 24 includes a collar 24.1 fixed to one side of the bottom of the support frame 14, and a pair of vertical plates 24.2 fixed to the ground. A Z-shaped pedal 24.3 is provided between the pair of vertical plates 24.2. The side of the Z-shaped pedal 24.3 is rotatably connected to the vertical plates 24.2. A limit block 24.4 with a right-angled triangle cross-section is fixed to the bottom of one end of the Z-shaped pedal 24.3. The inclined surface of the limit block 24.4 faces the collar 24.1, and the limit block 24.4 is movably placed in the collar 24.1 from above. A limit rod 24.5 is fixed to the top of the other end of the Z-shaped pedal 24.3, which movably abuts the side of the vertical plate 24.2 and makes the Z-shaped pedal 24.3 in a horizontal posture. A compression spring 24.6 is fixed to the bottom of the other end of the Z-shaped pedal 24.3.

[0040] There are locking mechanisms 24 at both ends of the sector track 23. Therefore, two rings 24.1 are fixed to one side of the bottom of the support frame 14. When the support frame 14 moves to any end on the sector track 23, it drives the ring 24.1 to touch the inclined surface of the limit block 24.4. One end of the Z-shaped pedal 24.3 is squeezed and tilted, and the other end of the Z-shaped pedal 24.3 drops and squeezes the compression spring 24.6. The ring 24.1 presses against the vertical plate 24.2 to lock the support frame 14. At the same time, the limit block 24.4 is placed above the center of the ring 24.1. The compression spring 24.6 releases the pressure to drive the other end of the Z-shaped pedal 24.3 to rise, and one end of the Z-shaped pedal 24.3 drops, and the limit block 24.4 buckles into the ring 24.1 to achieve locking.

[0041] Working principle: The working principle is the same as that of embodiment 1 or 2, except that when the furnace mouth is opened and the gun body 6 needs to move back and forth horizontally, the locking mechanism 24 limits the movement of the support frame 14, the horizontal reciprocating movement of the gun body 6 is more stable, and the support frame 14 will not be dragged. Specifically, the limiting rod 24.5 abuts the side of the vertical plate 24.2, so that the Z-shaped pedal 24.3 is in a horizontal posture, and the support frame 14 drives the collar 24.1 to touch the inclined surface of the limiting block 24.4, and the Z-shaped pedal 24.3 is in a low position. One end of the Z-shaped pedal 24.3 is squeezed and tilted, and the Z-shaped pedal 24.3 descends at the high end to squeeze the compression spring 24.6, and the ring 24.1 presses against the vertical plate 24.2 to block the support frame 14. At the same time, the limit block 24.4 is placed above the center of the ring 24.1, and the compression spring 24.6 releases the pressure to drive the high end of the Z-shaped pedal 24.3 to rise, and the low end of the Z-shaped pedal 24.3 descends, and the limit block 24.4 is buckled into the ring 24.1. The ring 24.1 is hooked by the limit block 24.4 and cannot move, thereby achieving locking.

[0042] The Z-shaped pedal 24.3 is stepped on at one end of the high position to make it descend, and the Z-shaped pedal 24.3 is tilted at one end of the low position, and the limit block 24.4 comes out of the collar 24.1 to achieve unlocking.

[0043] When unloading or stopping, the rotating frame 8 rotates, and the support frame 14 moves along the track curve on the sector track 23 through the roller 25, and cooperates with the rotation of the rotating frame 8 to drive the gun body 6 to move horizontally to achieve giving way.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
