Description

Technical Field

[0001] This invention belongs to the technical field of ferromolybdenum smelting equipment, and specifically discloses a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting. Background Technology

[0002] After molten ferromolybdenum ore is smelted in a furnace, the ferromolybdenum particles and slag separate under high temperature conditions. The ferromolybdenum particles settle and converge to form ferromolybdenum ingots, while the slag floats and fuses to form ferromolybdenum slag. After the melt is allowed to stand for about 30 minutes, the ferromolybdenum particles and slag can be fully separated. The ferromolybdenum slag and ferromolybdenum ingots are in a layered state. A slag discharge port is opened on the lower side wall of the furnace cylinder to discharge slag. During slag discharge, the slag discharge port, which is sealed by refractory mud plug, is manually opened. Traditional slag discharge operation requires operators to use tools to poke the slag discharge port at close range. Operators are exposed to an ultra-high temperature environment of 1300-1500℃, facing multiple threats from molten slag splashes, toxic gases, and strong heat radiation. This poses a high risk of personal injury accidents and is extremely dangerous. In addition, manual operation is inefficient and random, making it difficult to adapt to the needs of modern smelting production.

[0003] Currently, the high-temperature resistance design of conventional industrial equipment on the market is only suitable for conventional high-temperature environments of 200-500℃. Some equipment is even designed only for temperature scenarios of 100 degrees Celsius. None of them can withstand the ultra-high temperature radiation and slag corrosion of 1300-1500℃ in ferromolybdenum smelting. At the same time, there is no automated equipment suitable for ultra-high temperature slag discharge conditions in ferromolybdenum smelting and the entire non-ferrous metals industry. The automation and unmanned transformation of the slag discharge process has become a technical pain point that the industry urgently needs to solve. Summary of the Invention

[0004] To address the problems in the background technology, this invention discloses a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting, comprising a slag-pumping unit and a folding unit. The slag-pumping unit can quickly break through the hard slag shell and the plugging mud and retract, realizing automated unmanned operation and remote control of slag discharge. At the same time, through a comprehensive heat insulation and protection design, the equipment can operate stably under ultra-high temperature conditions of thousands of degrees, effectively breaking through the technical bottleneck of the industry.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting includes a slag-discharging unit and a folding unit. The folding unit includes a base and a folding beam. One end of the folding beam is hinged to the base via a hinge assembly, and the other end of the folding beam is detachably connected to the slag-discharging unit. Under the action of the hinge assembly, the folding beam can drive the slag-discharging unit to fold or unfold relative to the base. The slag-discharging unit includes a slide, a slide table, and a drill rod. The drill rod is movably connected to the bottom of the slide via the slide table. Under the action of the driving mechanism, the drill rod can move forward relative to the slide via the slide table to extend the front end of the drill rod or move backward relative to the slide to retract the front end of the drill rod.

[0006] Furthermore, the high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device includes a hinge assembly comprising a winch mounted on a base. The output end of the winch is connected to a sheave wound with a steel wire rope. One end of the folding beam adjacent to the base is hinged to the base via a hinge shaft. A pulley is provided above the middle of the folding beam. One end of the steel wire rope is connected to the sheave, and the other end of the steel wire rope is connected to the folding beam via the pulley. Under the action of the winch, by adjusting the length of the steel wire rope released by the sheave, the angle between the folding beam and the base can be adjusted, thereby enabling the folding beam to unfold or fold relative to the base.

[0007] Furthermore, the high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device includes a driving mechanism comprising a cylinder disposed below the folding beam. The free end of the cylinder piston rod is fixedly connected to the end of the drill rod via a drill rod seat. The drill rod seat is slidably connected to the slide. A front baffle is provided at the front end of the slide, and a through hole is provided on the front baffle for the drill rod to pass through. When the cylinder piston rod extends, the front end of the drill rod can pass through the through hole and extend forward to discharge slag. When the cylinder piston rod retracts, the drill rod can retract backward.

[0008] Furthermore, the high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device also includes a programmable controller, a limit switch, and an angle sensor. The angle sensor is located at one end of the folding beam adjacent to the base and is used to measure the angle of rotation of the folding beam relative to the base. The limit switch is located at the end of the slide away from the folding beam and is used to limit the displacement of the drill rod relative to the slide. The programmable controller is connected to the winch, cylinder, limit switch, and angle sensor.

[0009] Furthermore, the high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device has side baffles on both sides of the junction between the folding beam and the base, and a splash guard is connected between the side baffles by a torsion spring.

[0010] Furthermore, the high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device has heat-insulating covers on the outside of the winch, cylinder and drill rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are: This invention relates to a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting, comprising a slag-pumping unit and a folding unit. The folding unit includes a base and a folding beam. One end of the folding beam is hinged to the base via a hinge assembly, and the other end of the folding beam is detachably connected to the slide of the slag-pumping unit. The folding beam can drive the slide to fold or unfold relative to the base. A drill rod is movably connected to the bottom of the slide. Under the action of the driving mechanism, the drill rod can move forward relative to the slide, causing the tip of the drill rod to extend and quickly puncture the hard slag shell and the taphole clay sealant to discharge the slag. After puncturing the hard slag shell and the taphole clay sealant, the drill rod moves backward relative to the slide, causing the tip of the drill rod to quickly retract and withdraw, avoiding damage to the equipment by the high-temperature molten slag. This achieves automated, unmanned operation and remote control of the slag discharge operation, reducing safety risks. This invention relates to a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting. Equipped with an intelligent electrical control system consisting of a programmable controller, angle sensor, and limit switch, it enables remote one-button operation and automated, unmanned operation. The device is convenient to operate and highly safe. After the device is started, the program controls the automatic completion of a series of actions, including device positioning, slag removal with a chisel, rapid retraction, and device folding. This completely replaces the traditional manual close-range slag removal operation. Operators are not exposed to ultra-high temperature and high-risk environments of 1300-1500℃, eliminating the risk of personal injury at the source and significantly improving the safety and automation level of slag discharge operations.

Detailed Implementation

[0014] To better understand the present invention, the following embodiments further illustrate the content of the invention, but the scope of protection of the present invention is not limited to the following embodiments. Numerous specific details are set forth in the following description to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0017] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0018] Combined with appendix Figure 1-3This invention details a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting, comprising a slag-discharging unit 1 and a folding unit 2. The folding unit 2 includes a base 2.1 and a folding beam 2.5. One end of the folding beam 2.5 is hinged to the base 2.1 via a hinge assembly. The base 2.1 is fixedly connected to a wall, mounting frame, or movable seat via a connector. The movable seat allows adjustment and locking of the base 2.1's position. The other end of the folding beam 2.5 is detachably connected to the slide 1.1 of the slag-discharging unit 1. Under the action of the hinge assembly, the folding beam 2.5 can fold or unfold the slide 1.1 relative to the base 2.1. During non-operational periods, the slag-discharging unit 1 and the folding unit 2 can fold relative to the base, significantly saving valuable workshop space. A sliding table 1.7 is movably connected at the bottom of the slide 1.1 to a device adapted for ultra-high temperatures of 1300-1500℃. The high-temperature resistant drill rod 1.2, under the action of the drive mechanism, can move forward relative to the slide 1.1 to extend its front end or move backward relative to the slide 1.1 to retract its front end. The equipment is operated manually with a single button press via a programmable controller. After startup, the program automatically completes the entire process of positioning, slag removal, and retraction. When slag discharge is required, the drive mechanism provides high-strength, precisely controllable propulsion. Under the action of the drive mechanism, the drill rod 1.2 moves forward relative to the slide 1.1, causing its front end to quickly extend and pierce the hard slag shell and stemming material, thus discharging the slag. After the drill rod 1.2 pierces the hard slag shell and stemming material, it moves backward relative to the slide 1.1, causing its front end to quickly retract and withdraw, preventing damage to the equipment from the high-temperature molten slag, achieving automatic slag discharge, and reducing safety risks. This invention relates to a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting. Its foldable structure design balances space utilization and operational stability. The folding beam allows the slag-clearing unit to fold or unfold flexibly relative to the base. During non-operational periods, the equipment can be folded away for storage, significantly saving valuable workshop space. During operation, precise positioning of the drill rod is achieved through the precise coordination of a winch and angle sensor. Combined with the rapid extension and retraction of the drill rod driven by a cylinder, it can efficiently break through hard slag shells and taphole blockages, and quickly retract after clearing slag, preventing damage from ultra-high-temperature molten slag. This improves equipment lifespan and operational stability, making it an ideal solution for ferromolybdenum smelting. This is the first set of automated equipment designed for ultra-high temperature slag discharge operations in the ferromolybdenum smelting industry. It is also the first automated device in the entire non-ferrous metals industry adapted to ultra-high temperature slag discharge operations at 1,000 degrees Celsius. It is specifically designed for ultra-high temperature slag discharge operations in ferromolybdenum smelting at 1,300-1,500 degrees Celsius. It realizes automated, unmanned, and remote control of slag discharge operations, filling the technological gap in automated slag discharge equipment for ultra-high temperature conditions in the industry. It breaks through the current situation in the industry where slag discharge operations rely on manual labor and there is no dedicated automated equipment. It provides core technical support for the automation and intelligent transformation of ultra-high temperature processes in ferromolybdenum smelting and the non-ferrous metals industry, and has significant pioneering and demonstrative significance in the industry.

[0019] As an optional design, the preferred high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device includes a winch 2.2 mounted on a base 2.1. The motor and reducer ends of the winch are wrapped with 30mm thick insulation cotton. A heat-insulating winch cover 3 is installed over the winch 2.2, forming a double-layer heat insulation protection suitable for ultra-high temperature operating conditions. The output end of the winch 2.2 is connected to a reel wound with a steel wire rope. One end of the folding beam 2.5 adjacent to the base 2.1 is hinged to the base 2.1 via a hinge shaft. A pulley 2.4 is located above the middle of the folding beam 2.5. One end of the steel wire rope is connected to the reel, and the other end is connected to the pulley 2.4. Under the action of the winch 2.2, the angle between the folding beam 2.5 and the base 2.1 can be adjusted by adjusting the length of the steel wire rope released from the reel, allowing the folding beam 2.5 to unfold or fold relative to the base 2.1. When slag discharge is required, the winch 2.2... When winch 2.2 starts, the length of the wire rope released by the reel increases, and the folding beam 2.5 unfolds relative to the base 2.1, allowing the drill rod 1.2 to approach the slag discharge port at an approximately horizontal angle. After the drill rod 1.2 breaks through the hard slag shell and the plugging mud, winch 2.2 moves in the opposite direction, and the length of the wire rope released by the reel shortens. The folding beam 2.5 drives the drill rod 1.2 through the slide 1.1, causing the drill rod 1.2 to retract rapidly, preventing damage to the equipment from the high-temperature molten slag. It should be noted that in this embodiment, the winch 2.2 is used to adjust the length of the wire rope released by the reel, thereby adjusting the angle between the folding beam 2.5 and the base 2.1. Alternatively, a cylinder or hydraulic cylinder can be used, with the cylinder body hinged to the base 2.1 and the piston rod end hinged to the folding beam 2.5. This also allows the folding beam 2.5 to unfold or fold relative to the base 2.1, meeting the adaptation requirements of different operating scenarios.

[0020] As an optional design, the preferred high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device includes a drive mechanism comprising a cylinder 2.6 positioned below the folding beam 2.5. A heat-insulating protective shell 2.7 covers the cylinder 2.6, and insulation cotton is cut outside the cylinder 2.6 to wrap and secure it from the bottom in a U-shape, forming dedicated heat insulation protection for the cylinder. Due to the high temperature of the slag flow and strong high-temperature radiation on site, most exposed wiring has heat insulation measures to prevent high-temperature burnout of wiring and other components, thus avoiding machine damage. First, a 30mm thick layer of insulation cotton is laid inside the cable trough, then laid in a U-shape inside the trough. The cable air pipe is then placed inside the insulation cotton, and finally, a protective shell 2.7 is placed on top, forming a double-layer thermal insulation protection for the cable. The free end of the piston rod of the cylinder 2.6 is fixedly connected to the drill rod seat 1.6 via a cover 1.5, and the end of the drill rod 1.2 is fixedly connected to the cover 1.5. A cover plate 1.3 is provided at the bottom of the slide 1.1 along the axial direction of the slide 1.1. Guide rails extending along the axial direction of the slide 1.1 are respectively provided on both sides of the bottom of the cover plate 1.3. The guide rails are horizontal... The cross-section is L-shaped. The upper end of the vertical section of the guide rail is fixedly connected to the bottom of the cover plate 1.3. The lower end of the vertical section of the guide rail is bent outward at 90 degrees to form a horizontal section. The top of the drill rod holder 1.6 is fixedly connected to the slide table 1.7. A slider 1.4 matching the guide rail is set on the top of the slide table 1.7. The horizontal section of the slider 1.4 is slidably connected to the top of the horizontal section of the guide rail, and the vertical section of the slider 1.4 is slidably connected to the outer side of the horizontal section of the guide rail. Under the action of the guide rail and the slide table 1.7, the drill rod holder 1.6 and the slide 1.1... The sliding connection has a front baffle 1.0 at the front end of the slide 1.1. The front baffle 1.0 has a through hole for the drill rod 1.2 to pass through. When the piston rod of the cylinder 2.6 extends, the front end of the drill rod 1.2 can pass through the through hole and extend forward to poke and discharge slag from the slag discharge port. When the piston rod of the cylinder 2.6 retracts, the drill rod 1.2 can quickly retract to its original position. The drill rod 1.2 is covered with a heat-insulating cover 1.8 to protect the drill rod 1.2, guide rail, slide table 1.7 and other core components from damage caused by ultra-high temperature molten slag and heat radiation.

[0021] As an optional design, the preferred high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device also includes a programmable controller, limit switches, and an angle sensor 2.3. The programmable controller is housed in an electrical control box, the lower part of which is covered with heat-insulating cotton and mounted on a heat-insulating steel plate. The limit switches are not shown in the figure; exposed cable sections are insulated with heat-insulating cotton to fully adapt to ultra-high temperature operating environments of 1300-1500℃. The angle sensor 2.3 is located at one end of the folding beam 2.5 near the base 2.1. The angle sensor 2.3 measures the angle of rotation of the folding beam 2.5 relative to the base 2.1, providing accurate data support for automatic program positioning. The limit switch is located at the end of the slide 1.1 away from the folding beam 2.5. The limit switch limits the displacement of the drill rod 1.2 relative to the slide 1.1 to prevent equipment collision damage. The programmable controller is connected to the winch 2.2, cylinder 2.6, limit switches, and angle sensor 2.3. The controller commands the winch 2.2 to adjust the angle between the folding beam 2.5 and the base 2.1. The programmable controller commands the cylinder 2.6 to adjust the extension and retraction of the drill rod 1.2, realizing automatic control of slag removal and retraction. When the drill rod 1.2 extends to the position of the drill rod seat 1.6 near the front baffle 1.0, the limit switch sends information to the programmable controller, which sends a command to the cylinder 2.6 to stop the piston rod of the cylinder from extending, thus avoiding contact and collision between the drill rod seat 1.6 and the front baffle 1.0. The front baffle 1.0 serves as a guide and can also effectively block molten slag splashing, further improving the equipment's protection capability. The programmable controller adopts Siemens S7-200 series products to realize automated, unmanned operation and remote control of slag discharge. It should be noted that the high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device of the present invention is also equipped with an emergency stop button. In case of emergency, pressing the emergency stop button can immediately terminate all actions of the automatic slag discharge device. This invention relates to a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting. It features precise program-linked control, significantly improving operational efficiency. An angle sensor accurately collects the rotation angle of the folding beam, and limit switches precisely restrict the displacement of the drill rod. A programmable controller provides unified command control to the winch and cylinders, achieving synchronized response and precise adjustment of each mechanism's actions. This avoids the randomness and errors of manual operation, making slag removal and discharge more efficient and precise, greatly improving the overall efficiency of slag discharge operations in ferromolybdenum smelting. It adapts to the operational needs of modern smelting production lines, achieving automated and unmanned operation. The device is convenient to operate and highly safe. Equipped with an intelligent electrical control system consisting of a programmable controller, angle sensors, and limit switches, it enables remote one-button operation. After startup, the program automatically completes a series of actions, including equipment positioning, drill rod slag removal, rapid retraction, and equipment folding. This completely replaces traditional manual close-range slag removal operations. Operators are not exposed to ultra-high temperatures (1300-1500℃) and high-risk environments, eliminating personal injury risks at the source and significantly improving the safety and automation level of slag discharge operations.

[0022] As an optional design, the high-temperature resistant foldable ferromolybdenum smelting automatic slag discharge device is preferred. Side baffles 4 are respectively installed on both sides of the junction of the folding beam 2.5 and the base 2.1. A splash guard 5 is connected between the side baffles 4 by a torsion spring, which effectively blocks the splashing of ultra-high temperature molten slag at 1300-1500℃. 50mm heat insulation cotton is installed inside the side baffles and splash guards. The heat insulation cotton is about 610mm wide, corresponding to the width of the side baffles 650mm. The heat insulation cotton is fixed to the wall side of the side baffle with screws or tie wires through the holes on the cover, forming a four-sided coverage of the base 2.1, achieving all-round heat insulation and splash protection. When the folding beam 2.5 rotates and unfolds relative to the base 2.1, the splash guard 5 can move relative to the side baffles 4 under the action of the torsion spring, protecting the components at the junction of the folding beam 2.5 and the base 2.1 while ensuring that the movement of the folding beam 2.5 is not interfered with, thus taking into account both equipment protection and operational flexibility. This invention relates to a high-temperature resistant, foldable, automatic slag discharge device for ferromolybdenum smelting. It features exclusive ultra-high temperature protection, adapting to the harsh conditions of ferromolybdenum smelting. Specifically designed for ultra-high temperatures of 1300-1500℃ in ferromolybdenum smelting, it employs a unique heat insulation protection system, unlike conventional equipment on the market with a high-temperature resistance limit of 200-500℃. This system utilizes multiple measures, including an insulated outer shell for core components, thick layers of insulation cotton for critical areas, double-layer insulation for the wiring channels, and splash guards to prevent molten slag splashing. This comprehensive heat insulation protection system ensures stable operation of the equipment under the harsh conditions of ultra-high temperature radiation and molten slag splashing, solving the technical problem that conventional equipment cannot adapt to the ultra-high temperature slag discharge conditions in ferromolybdenum smelting.

[0023] The working process of this invention is as follows: During slag discharge, the operator remotely starts the equipment with a single button. The programmable controller (PLC) issues a command to start the winch 2.2. The winch 2.2 drives the reel to rotate and release the wire rope. The folding beam 2.5 automatically unfolds relative to the base 2.1. The angle sensor 2.3 collects the rotation angle of the folding beam 2.5 in real time and transmits it to the PLC. After the folding beam 2.5 rotates to the designated position, the angle sensor 2.3 sends a signal to the PLC. The PLC then commands the winch 2.2 to stop working and simultaneously sends an extension command to the cylinder 2.6. The piston rod of the cylinder 2.6 extends and pushes the slide 1.7 to move the drill rod 1.2 forward rapidly, breaking through the hard slag shell and stemming blockage, achieving automated and unmanned slag discharge. After slag discharge is completed, the PLC sends a retraction command to the cylinder 2.6, and the drill rod 1.2 quickly retracts to a safe position to avoid being overtaken. High-temperature molten slag damage; simultaneously, the programmable controller sends a command to the winch 2.2, driving the reel to rotate in the opposite direction to retract the wire rope, and the folding beam 2.5 drives the slag-clearing unit 1 to automatically fold relative to the base 2.1, so that the entire equipment is away from the ultra-high temperature molten slag area of ​​the slag discharge port, avoiding damage to the equipment by high-temperature molten slag, and completing a fully automatic slag discharge operation. No manual intervention is required throughout the process. The present invention is a high-temperature resistant foldable automatic slag discharge device for ferromolybdenum smelting. It realizes one-button operation by manual operation, and the program automatically completes a series of actions such as positioning, slag clearing, retraction, and folding. The entire process is automated and unmanned.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
