Description

Technical Field

[0001] This application relates to the field of industrial silicon tapping technology, and more particularly to an industrial silicon tapping device. Background Technology

[0002] Industrial silicon smelting furnaces are a common type of equipment used to produce industrial silicon. When using industrial silicon smelting furnaces, it is usually necessary to shield the flame at the furnace opening. Most existing industrial silicon smelting furnaces use simple door panels or manual sliding doors. Before the industrial silicon is discharged from the furnace, the door panel is manually pushed to the furnace opening position, and a small opening is opened on the door. The operator then operates tools through this small opening.

[0003] However, manually opening and closing the door exposes people to high temperatures, increasing their workload and risk of injury. Manual operation is also inefficient. Furthermore, the conventional door opens by moving horizontally, which requires a large space outside the furnace opening of the industrial silicon smelting furnace. In addition, the conventional door track is set on the ground and supported by a support structure, which causes slag and ash ejected from the furnace opening to fall onto the track on the ground, affecting the opening and closing of the furnace opening. Summary of the Invention

[0004] This application proposes an industrial silicon furnace tapping device that has the advantages of high working efficiency and prevention of operators from high temperature injury, in order to solve the technical problems existing in the opening, closing and moving of the door panel of the existing industrial silicon smelting furnace.

[0007] The shielding door mechanism includes a steel rail set on the outer periphery of the electric arc furnace, and an automatic door is installed on the steel rail. The automatic door is driven by a motor to move along the steel rail. When it is necessary to unload the furnace, the motor drives the automatic door to move the furnace outlet, and the unloading machine moves to the furnace opening to work. When it is not necessary to unload the furnace, the unloading machine moves the furnace outlet, and the motor drives the automatic door to move to the furnace opening to block the furnace.

[0008] In one embodiment of this application, the two shielding door mechanisms are respectively arranged on opposite sides of the electric arc furnace; the steel rail consists of three straight rail sections and two arc rail sections, the three straight rail sections are connected by the arc rail sections respectively, and hanging beams are fixedly installed at both ends of the steel rail. The steel rail is used to suspend the automatic door through the hanging mechanism, and the steel rail and the automatic door are suspended and installed on the periphery of the electric arc furnace through the hanging beams.

[0009] In one embodiment of this application, the hanging mechanism includes hanging plates movably disposed on both sides of a steel rail, a motor fixedly mounted on one of the hanging plates, and two rollers I are mounted on opposite sides of the two hanging plates via roller shafts.

[0017] By employing the above embodiments, the present invention has at least the following beneficial effects:

[0018] 1. The industrial silicon tapping equipment provided in this application controls the opening or closing of the furnace opening by setting a shielding door mechanism that moves along a steel rail around the periphery of the submerged arc furnace and is driven by a motor. This eliminates the need for manual operation, avoids the problem of people being exposed to high temperatures and suffering high-temperature injuries, and improves work efficiency.

[0019] 2. The steel rail consists of three straight sections and two curved sections. The three straight sections are connected by the curved sections, which allows the rail to be fixed around the perimeter of the electric arc furnace, reducing the space occupied by the steel rail and the automatic door. In addition, the roller I of the hanging mechanism in the shielding door mechanism can move along the curved rail, ensuring that the opening or closing movement control of the automatic door is not affected by the bending part of the steel rail.

[0020] 3. The interior of the automatic door is filled with refractory cement, and the sides of the automatic door are filled with heat insulation boards, which can isolate high temperature and prevent the flames and ash from the furnace mouth from burning the external operators.

[0021] 4. The automatic door is suspended on the steel rail by a hanging mechanism and driven by a motor to move along the steel rail, so that the automatic door is suspended around the perimeter of the electric arc furnace. The automatic door acts as a barrier. At the same time, compared with the method of setting the steel rail on the ground, it avoids the problem of slag and ash falling on the steel rail on the ground and affecting the movement of the automatic door to open and close the furnace opening.

[0022] 5. Brake cylinders are installed at both ends of the steel rail, and the brake cylinders are connected to the accumulator through oil pipe I. When the automatic door moves to one end of the steel rail to close the furnace opening, the inertia of the automatic door in the stopping stage pushes piston I to move, forcing the hydraulic oil in the brake cylinder into the accumulator for braking. At the same time, the accumulator converts the braking energy into potential energy, which, together with the locking device, locks the block, allowing the automatic door to stop precisely at the furnace opening. When it is opened again, the locking device is released from the block, the accumulator releases the stored potential energy, and pushes the automatic door to move. The auxiliary electrical system drives the automatic door from a stationary state to a moving state, reducing the traction force when the motor starts, avoiding the problem of motor overload, reducing energy consumption, and improving the efficiency of moving a large-mass automatic door.

[0023] 6. The locking device features a structure where the locking plate rotates around a positioning shaft. This, combined with a piston II and a sealing sleeve movable within a limiting cylinder, and oil pipes II connecting the two chambers of piston II on both sides of the limiting cylinder, ensures that the pressure on both sides is equal when the sealing sleeve seals the oil pipes II. This causes the limiting rod connected to one side of piston II to abut against the lower half of the locking plate. This, combined with the potential energy stored in the accumulator, keeps the locking block in a positioned state. When controlling the automatic door to open the furnace opening, the locking plate is easily released, unaffected by the potential energy stored in the accumulator. This allows for high accumulator potential energy storage while facilitating the release of the auxiliary motor to drive the automatic door, further improving the automatic door's movement control effect.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] Example 1

[0039] Please see Figure 1 and Figure 2 An industrial silicon tapping furnace device includes a tapping machine 4 and a shielding door mechanism. A furnace opening is located on the outer periphery of a submerged arc furnace 3. The shielding door mechanism includes a steel rail 1 located on the outer periphery of the furnace 3. An operating door 5 is located in the middle of the automatic door 2 of the shielding door mechanism. The operating door 5 is limited by a stop bar on the automatic door 2, allowing it to open and close. Opening the operating door 5 allows for observation and temporary operation, while closing it blocks the furnace fire. The automatic door 2 is driven by a motor 7 mounted on the shielding door mechanism to move along the steel rail 1. When tapping is required, the motor 7 drives the automatic door 2 to move to the furnace opening, and the tapping machine 4 moves to the furnace opening to operate. When tapping is not required, the motor 7 drives the automatic door 2 to move to the furnace opening to block the fire. The furnace opening is opened or closed by the motor 7 driving the automatic door 2 to move along the steel rail 1. Furthermore, both the tapping machine 4 and the shielding door mechanism can be connected to a control device to achieve coordinated automatic control, thereby improving the automation level of this embodiment. However, this embodiment does not limit the method of automatic control. By adopting the above design, the embodiments of this application achieve the goal of eliminating the need for manual operation, avoiding the problem of people being exposed to high-temperature environments and suffering high-temperature injuries, and improving work efficiency.

[0040] Example 2

[0041] Please see Figures 2-3 An industrial silicon tapping device is disclosed, wherein two shielding door mechanisms are respectively arranged on opposite sides of a submerged arc furnace 3, so that a single shielding door mechanism can correspond to the two furnace doors of the submerged arc furnace 3. However, the embodiments of this application are not limited thereto. The shielding door mechanism includes a steel rail 1 arranged on one side of the furnace opening of the submerged arc furnace 3. The steel rail 1 consists of three straight rail sections and two arc rail sections. The three straight rail sections are connected by arc rail sections. Around the periphery of the submerged arc furnace 3, there are... Figure 1The four furnace openings shown allow the track to be fixed around the perimeter of the electric arc furnace 3, reducing the space occupied by the steel rail 1 and the automatic door 2. Hanging beams 12 are fixedly installed at both ends of the steel rail 1. The automatic door 2 is suspended from the steel rail 1 via a hanging mechanism. The hanging beams 12 are fixedly installed on the roof of the factory building. By suspending the steel rail 1 via the hanging beams 12, the automatic door 2 is suspended around the perimeter of the electric arc furnace 3, serving as a barrier. Compared to placing the steel rail 1 on the ground, this avoids slag and ash falling onto the ground-level steel rail 1, which could affect the movement and opening / closing of the furnace openings of the automatic door 2. The interior of the automatic door 2 is filled with refractory cement, and the sides of the automatic door 2 are filled with heat insulation boards, thus insulating against high temperatures and preventing burns to external operators from flames and ash emitted from the furnace openings.

[0042] Please see Figure 4 The hanging mechanism includes hanging plates 6 movably mounted on both sides of the steel rail 1. A motor 7 is fixedly mounted on one of the hanging plates 6. Rollers I8 are mounted on opposite sides of the two hanging plates 6 via rollers. There are two rollers I8. The rollers I8 are tactilely connected to the steel rail 1. A hanging shaft located below the rollers I8 is fixedly installed between the two hanging plates 6. A hanger 9 is mounted on the hanging shaft. The bottom end of the hanger 9 is fixedly connected to the top of the automatic door 2. The motor 7 drives the rollers I8 to rotate, causing the rollers I8 to move along the steel rail 1, thereby driving the hanger 9 and the automatic door 2 to move along the rail, realizing the automatic movement of the door.

[0043] A positioning plate 10 is fixedly installed on the hanging plate 6. The middle part of the positioning plate 10 is designed as a groove, and a roller II 11 is provided on the positioning plate 10 in the groove. The outside of the roller II 11 is movably connected to the flange at the bottom of the rail 1. The roller II 11 is limited at the flange at the bottom of the rail 1 to ensure that the hanging mechanism can move stably along the rail 1 and avoid the problem of swaying and instability when the hanging mechanism drives the automatic door 2 to move along the rail 1.

[0044] Please see Figure 3 and Figure 5Two L-shaped plates 13 are fixedly installed on the hanging beams 12 at both ends of the rail 1. The two L-shaped plates 13 are located on opposite sides of the hanging beam 12. A limiting plate 14 is fixedly installed on the end of the L-shaped plate 13 away from the hanging beam 12. A brake cylinder 15 is fixedly installed on the side of the limiting plate 14 facing the automatic door 2. A piston I 16 is movably fitted inside the brake cylinder 15. An oil pipe I 17 is connected to one side of the brake cylinder 15. The oil pipe I 17 is located away from the brake cylinder 16. One end of 5 is connected to an accumulator 18. The accumulator 18 is connected to the chamber of the brake cylinder 15, which is filled with hydraulic oil. A crossbar 20 is fixedly connected to the top of the side of the automatic door 2. A locking block 21 is fixedly connected to the end of the crossbar 20 away from the automatic door 2. A horizontal shaft 22 is fixedly connected to the end of the locking block 21 away from the crossbar 20. The outer diameter of the locking block 21 decreases uniformly from the crossbar 20 to the horizontal shaft 22. A locking device 19 is fixedly installed at the bottom of the L-shaped plate 13. The locking device 19 is locked to the locking block 21.

[0045] The positioning device 19 includes a vertical tube 191, a slider 192 is movably fitted inside the vertical tube 191, a locking shaft 193 is fixedly connected to the top of the slider 192, the locking shaft 193 is movably engaged with the locking block 21, a linkage shaft 194 is fixedly connected to the bottom of the slider 192, the linkage shaft 194 is driven to move by a solenoid valve 195, a cover plate is fixedly fitted to the top of the vertical tube 191, and a through hole is opened on the cover plate, the cover plate is movably engaged with the locking shaft 193.

[0046] The interior of the automatic door 2 is filled with a large amount of refractory cement, resulting in a large overall mass of the shielding door mechanism. When the automatic door 2 moves towards the brake cylinder 15 at one end of the rail 1, the automatic door 2 drives the crossbar 20, the locking block 21, and the horizontal shaft 22 to move towards the brake cylinder 15. The horizontal shaft 22 moves into the brake cylinder 15 and pushes the piston I 16 to move. At this time, the motor 7 that drives the automatic door 2 stops, and the piston I 16 moves to the other side of the brake cylinder 15 under the pushing action of the horizontal shaft 22. The piston I 16 pushes the brake cylinder 15... Hydraulic oil is pumped into the accumulator 18 via oil pipe I17. Utilizing the inclined design of the outer side of the locking block 21, as the locking block 21 moves towards the piston I16, it pushes the locking shaft 193 downwards. Once the locking block 21 passes the locking shaft 193, the locking shaft 193 returns to its original position, limiting the locking block 21 on the side away from the horizontal axis 22. During this process, hydraulic oil enters the accumulator 18 to store energy, simultaneously braking the movement of the piston I16, thereby braking the automatic door 2. This continues until the locking block 21 moves to the locking shaft 193 and the brake cylinder. When the automatic door 2 is stopped, the locking shaft 193 engages the locking block 21, keeping the automatic door 2 in a stopped state. At this time, the automatic door 2 stops precisely at the entrance of the blast furnace 3, thus accurately controlling the stopping position of the automatic door 2 and ensuring that the automatic door 2 effectively blocks the entrance of the blast furnace 3. When the furnace opening needs to be opened, the starting motor 7 drives the automatic door 2 to move along the steel rail 1, while the solenoid valve 195 opens, pulling the linkage shaft 194, slider 192, and locking shaft 193 away from the locking block 21, thereby releasing the locking block 21 and storing the contents. The accumulator 18 releases the potential energy stored in the automatic door 2 when it brakes. The hydraulic oil in the accumulator 18 flows back to the brake cylinder 15 through the oil pipe I 17, pushing the piston I 16 to reset and move. The piston I 16 pushes the horizontal shaft 22, the locking block 21 and the horizontal bar 20 to move away from the brake cylinder 15, thereby assisting the motor 7 in driving the automatic door 2 from a stationary state to a moving state. This reduces the traction force when the motor 7 starts, avoids the problem of the motor 7 being easily overloaded, reduces energy consumption, and improves the efficiency of moving the large-mass automatic door 2.

[0047] When there are two automatic doors 2 on each rail 1, the two automatic doors 2 are fixedly connected to the side facing the brake cylinder 15 with crossbars 20. The middle of the rail 1 is provided with brake cylinders 15, pistons I 16 and oil pipes I 17 that are the same as those at both ends of the rail 1 but in opposite directions. The oil pipes I 17 are connected to the accumulators 18 that are close to it. When there is only one automatic door 2 on each rail 1, the automatic door 2 is fixedly connected to the side facing the brake cylinder 15 with crossbars 20. When there is only one automatic door 2, the automatic door 2 has a longer travel distance. At this time, the energy after braking is stored as potential energy in the accumulator 18, which is more conducive to the auxiliary motor 7 driving the automatic door 2 from a stationary state to a moving state.

[0048] Example 3

[0049] Please see Figure 4 The hanging mechanism includes hanging plates 6 movably mounted on both sides of the steel rail 1. A motor 7 is fixedly mounted on one of the hanging plates 6. Rollers I8 are mounted on opposite sides of the two hanging plates 6 via rollers. There are two rollers I8. The rollers I8 are tactilely connected to the steel rail 1. A hanging shaft located below the rollers I8 is fixedly installed between the two hanging plates 6. A hanger 9 is mounted on the hanging shaft. The bottom end of the hanger 9 is fixedly connected to the top of the automatic door 2. The motor 7 drives the rollers I8 to rotate, causing the rollers I8 to move along the steel rail 1, thereby driving the hanger 9 and the automatic door 2 to move along the rail, realizing the automatic movement of the door.

[0050] A positioning plate 10 is fixedly installed on the hanging plate 6. The middle part of the positioning plate 10 is designed as a groove, and a roller II 11 is provided on the positioning plate 10 in the groove. The outside of the roller II 11 is movably connected to the flange at the bottom of the rail 1. The roller II 11 is limited at the flange at the bottom of the rail 1 to ensure that the hanging mechanism can move stably along the rail 1 and avoid the problem of swaying and instability when the hanging mechanism drives the automatic door 2 to move along the rail 1.

[0051] Please see Figures 7-9 Two L-shaped plates 13 are fixedly installed on the hanging beams 12 at both ends of the rail 1.

The outer diameter of the locking block 21 decreases uniformly from the crossbar 20 to the horizontal shaft 22. A locking device 19 is fixedly installed at the bottom of the L-shaped plate 13. The locking device 19 is engaged with the locking block 21. A limiting device 24 and an adjusting device 25 are provided on the inner side of the L-shaped plate 13, located directly below the brake cylinder 15.

[0052] The positioning device 19 includes a positioning plate 196, a positioning shaft 197 is movably fitted in the middle of the positioning plate 196, the two ends of the positioning shaft 197 are respectively fixedly sleeved with two L-shaped plates 13, the top of the positioning plate 196 is movably sleeved with the positioning block 21, and a torsion spring 198 is provided between the inner sidewall of the positioning plate 196 and the L-shaped plate 13 and is movably sleeved outside the positioning shaft 197. The torsion of the torsion spring 198 keeps the positioning plate 196 in a vertical state.

[0053] The limiting device 24 includes a limiting cylinder 241. The inner diameter of the chamber on the side of the limiting cylinder 241 away from the regulating device 25 is larger than the inner diameter of the chamber on the side closer to the regulating device 25. A piston II 242 is movably fitted in the chamber on the side of the limiting cylinder 241 away from the regulating device 25. A limiting rod 23 is fixedly connected to one side of the piston II 242. The end of the limiting rod 23 away from the piston II 242 is movably connected to one side of the lower half of the clamping plate 196. The limiting cylinder 241 is located on the side closer to the regulating device 25. The chamber is fitted with a sealing sleeve 244. A spring 1 245 connects the sealing sleeve 244 and the piston 242. The two chambers in the limiting cylinder 241 are connected by two oil pipes 243. The oil pipes 243 are located on the upper and lower sides of the limiting cylinder 241. The part of the oil pipe 243 that connects to the chamber of the limiting cylinder 241 near the control device 25 is located in the middle of the chamber of the limiting cylinder 241 near the control device 25. The limiting cylinder 241 is filled with oil.

[0054] The control device 25 includes a tube 251, which is fixedly installed on the side of the limiting cylinder 241. A sliding block 252 is movably fitted inside the tube 251. An adjusting shaft 253 is fixedly connected to one side of the sliding block 252.

A spring II 255 is movably fitted on the tube 251 on the side of the sliding block 252 facing the limiting cylinder 241.

[0055] Unlike Embodiment 2, the clamping plate 196 is rotatable around the positioning shaft 197. This allows it to limit the movement of the clamping block 21 without affecting its movement. When the automatic door 2 moves towards the brake cylinder 15, the horizontal shaft 22 moves to contact the piston I 16, pushing the piston I 16 to move and pressurizing the hydraulic oil in the brake cylinder 15 into the accumulator 18. The accumulator 18 stores energy for braking. When the clamping block 21 passes the clamping plate 196, it overcomes the torque of the torsion spring 198. Figure 9As shown, the push plate 196 rotates clockwise around the positioning shaft 197. After the locking block 21 has completely passed through the plate 196, the torsion of the torsion spring 198 causes the plate 196 to return to a vertical state. At this time, the sealing sleeve 244 is in the state of blocking the oil pipe II 243. The oil pressure on both sides of the sealing sleeve 244 is the same, which causes the limiting rod 23 to limit the position below the plate 196, so that the locking block 21 is locked on one side of the plate 196, thereby keeping the automatic door 2 stationary in the center of the intersection. When it is necessary to open... When the motor 7 drives the automatic door 2 to move out of the furnace, the electromagnet 254 is energized, generating a magnetic repulsive force on the magnetic block on the sliding block 252. Using the oil pipe II 243 positioned on both sides of the limit cylinder 241, the sealing sleeve 244 experiences equal pressure on both sides. The magnetic repulsive force of the electromagnet 254 easily pushes the sliding block 252, the adjusting shaft 253, and the sealing sleeve 244 to move. This causes the sealing sleeve 244 to open the oil pipe II 243, connecting the two chambers of the piston II 242, and releasing the elastic potential energy from the accumulator 18. Hydraulic oil enters the brake cylinder 15 through oil pipe I17, pushing piston I16 to move. Auxiliary motor 7 drives automatic door 2 to move, and locking block 21 moves away from piston I16, causing locking plate 196 to rotate counterclockwise around positioning shaft 197. Under the action of locking plate 196 rotating counterclockwise, limit rod 23 can push piston II242 towards sealing sleeve 244 until locking block 21 moves with automatic door 2 and separates from locking plate 196. Locking plate 196 then moves under the torsion of torsion spring 198. The cylinder returns to a vertical position. Then, the electromagnet 254 is de-energized. The elastic force of the spring II 255 causes the sliding block 252 to move the adjusting shaft 253 and the sealing sleeve 244 toward the side of the electromagnet 254. The sealing sleeve 244 drives the spring I 245 to pull the piston II 242 until the sealing sleeve 244 completely blocks the oil pipe II 243. At this time, the oil pressure on both sides of the piston II 242 remains the same to ensure that after the next movement of the locking block 21 to the locking plate 196, the locking plate 196 can limit the locking block 21.

[0056] Compared to Embodiment 2, the limiting method for the locking block 21 is changed to the form of rotating the locking plate 196, and a limiting device 24 and a control device 25 are added. However, when the locking plate 196 is controlled to cancel the limiting of the locking block 21, it is only necessary to control the electromagnet 254 to be energized. Since the upper and lower sides of the sealing sleeve 244 are subjected to the same pressure, the locking block 21 can be easily released. This makes it easier to release the locking block 21 when the potential energy of the accumulator 18 is high.

[0057] When there are two automatic doors 2 on each rail 1, the two automatic doors 2 are fixedly connected to the side facing the brake cylinder 15 with crossbars 20. The middle of the rail 1 is provided with brake cylinders 15, pistons I 16 and oil pipes I 17 that are the same as those at both ends of the rail 1 but in opposite directions. The oil pipes I 17 are connected to the accumulators 18 that are close to it. When there is only one automatic door 2 on each rail 1, the automatic door 2 is fixedly connected to the side facing the brake cylinder 15 with crossbars 20. When there is only one automatic door 2, the automatic door 2 has a longer travel distance. At this time, the energy after braking is stored as potential energy in the accumulator 18, which is more conducive to the auxiliary motor 7 driving the automatic door 2 from a stationary state to a moving state.
