The swing frame 43 drives the combing frames 98 on the two groups of bent rods 97 through the push arm 96 to comb the slag transported on the two groups of chain plate conveyor belts 15 back and forth, so that the slag in the conveying state is spread out, which is conducive to the rapid dissipation and cooling of the heat carried inside, and also prevents the slag from clogging on the chain plate conveyor belt 15.

[0058] Working principle of a slag removal device for an electric arc furnace: During the slag removal operation of the slag material in the silicon-manganese alloy melt in a high-temperature environment in the electric arc furnace, the double-headed motor 41 is first controlled to start and drive the cam 42 to rotate, and the first slide rail 10 and the first slider 11 play a sliding support role on the swing frame 43. The cam 42 drives the swing frame 43 to move horizontally back and forth through the rotating head, and the swing frame 43 drives the piston 45 on the connecting rod 44 to work back and forth in the cylinder barrel 3. When the piston 45 is in the return stroke in the cylinder barrel 3, the piston 45 is in the return stroke. In the intake state, the air intake valve on the intake pipe 47 is controlled to open, and the passage from the four-way valve 46 to the two exhaust pipes 48 is controlled to close, so that the outside air is sucked into the cylinder barrel 3 by the piston 45 through the intake pipe 47. When the piston 45 is in the process exhaust state in the cylinder barrel 3, on the contrary, the air sucked into the cylinder barrel 3 is pressurized by the piston 45 and discharged into the opened passage from the four-way valve 46 to the two exhaust pipes 48, and then supplied to the two groups of pressure storage tanks 51 for temporary storage until the pressurized air source in the two groups of pressure storage tanks 51 is full.

[0059] Next, the pressurized air source in the two pressure storage tanks 51 is supplied to the head end space of the two long sealing cylinders 53 through the two telescopic short tubes 52. With the continuous supply of the two-way pressurized air source, the two long T-shaped rods 54 are forced to slide forward in the two long sealing cylinders 53 under the action of the pressure force, and while compressing the two long return springs 55, the two long T-shaped rods 54 drive the two groups of slag shovels 57 to extend forward synchronously through the two groups of connecting seats 56. At the same time, the pressurized air source in the two pressure storage tanks 51 passes through the telescopic long on the two pressurized angle tubes 71. After the tube 72 is fed into the two sets of four-way joints 73, it is fed into the bottom end space of the four sets of short sealing cylinders 75. Similarly, under the action of pressure, the four short T-shaped rods 76 are forced to slide upward in the four sets of short sealing cylinders 75, and while compressing the four short return springs 77, the four short T-shaped rods 76 drive the fixed frame 1, the fixed box 2 and the two sets of slag shovels 57 in the synchronous extension state to move upward as a whole through the two sets of brackets 78, so that the two sets of slag shovels 57 adjusted forward and upward reach the slag area in the silicon-manganese alloy melt in the ore-fired furnace;

[0060] After the two groups of slag shovels 57 are in place, the double-headed motor 41 is first controlled to pause, and then the first electric push rod 83 is controlled to start and drive the secondary bevel gear 82 to reach the meshing portion of the main bevel gear 81, and then the double-headed motor 41 is controlled to start again and the main bevel gear 81 that is meshed in place drives the secondary bevel gear 82 to rotate, and the secondary bevel gear 82 drives the reciprocating screw rod 84 to rotate forwardly. With the second slide rail 12 and the second slider 13 providing sliding support for the double-sided toothed plate 86, the reciprocating screw rod 84 drives the double-sided toothed plate 86 on the screw rod barrel 85 to move forward, and the double-sided toothed plate 86 that moves forward drives the two groups of transfer gears 87 on The slide 88 expands outward synchronously, and the two sets of slides 88 drive the two sets of slag shovels 57 to expand outward synchronously through the two sets of long sealing cylinders 53 and the long T-shaped rods 54, and after the slag area in the silicon-manganese alloy melt in the submerged arc furnace is fully covered, on the contrary, the two sets of slag shovels 57 are controlled to shrink inward, and the two sets of slag shovels 57 in the contracted and combined state gather all the slag in the silicon-manganese alloy melt in the submerged arc furnace, and the silicon-manganese alloy melt leaks from the sieve leakage holes 58 on the two sets of slag shovels 57 after the merger into the silicon-manganese alloy melt in the submerged arc furnace, and so on, all the slag in the silicon-manganese alloy melt in the submerged arc furnace can be scraped out;

[0061] After all the slag is removed, the first pressure relief valve on the first pressure relief pipe 6 and the second pressure relief valve on the second pressure relief pipe 74 are controlled to open, and the pressurized air source in the two groups of long sealing tubes 53 and the four groups of short sealing tubes 75 is discharged through the first pressure relief pipe 6 and the second pressure relief pipe 74, and the two long reset springs 55 and the four short reset springs 77 in the compressed state drive the two long T-shaped rods 54 and the four short T-shaped rods 76 to perform elastic reset, so that the two groups of slag scrapers 57 still in the contracted and merged state are reset backward and downward to the initial position. , and after the two groups of slag shovels 57 still in the contracted and merged state reach the top of the material receiving frame 16, on the contrary, the two groups of slag shovels 57 in the contracted and merged state are controlled to expand outward, so that the slag materials shoveled out of the two groups of slag shovels 57 fall into the material receiving frame 16 at the loading position of the two groups of conveying frames 14, and then the inclined material receiving frame 16 slides the slag materials onto the two groups of chain plate conveyor belts 15, first control the double-headed motor 41 and the first electric push rod 83 to pause, so that the first electric push rod 83 drives the secondary bevel gear 82 to disengage from the meshing part of the main bevel gear 81 to the initial position;

[0062] After the slag material is divided and slides onto the two sets of chain plate conveyor belts 15, the second electric push rod 91 is first controlled to open and drive the driving bevel gear 92 to move down and get stuck in the meshing part of the driven bevel gear 93, and then the double-headed motor 41 is controlled to open again and drive the driven bevel gear 93 to rotate through the meshing driving bevel gear 92, and the driven bevel gear 93 drives the driving roller frame 94 to rotate accordingly. With the auxiliary transmission cooperation of a number of driven roller frames 95 to the two sets of chain plate conveyor belts 15, the driving roller frame 94 drives the two sets of chain plate conveyor belts 15 to transport the slag material forward. At the same time, the swing frame 43 still drives the piston 45 on the connecting rod 44 to work back and forth in the cylinder barrel 3, and the horizontal reciprocating swing frame 43 also drives the two sets of bent rods 97 on the push arm 96 to move accordingly, and the two sets of bent rods 97 moving horizontally drive the two sets of combing frames 98 to spread and comb the slag transported on the two sets of chain plate conveyor belts 15 back and forth, so that the heat in the slag transported on the two sets of chain plate conveyor belts 15 can be quickly dissipated and cooled, and at the same time, the slag can be prevented from blocking the two sets of chain plate conveyor belts 15, thereby completing the slag removal operation in the silicon-manganese alloy molten liquid in the ore-fired furnace.

[0063] It should be noted that the specific model specifications of the double-headed motor 41 and the electric push rod need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
