Abstract
Description
Technical Field
[0001] The invention belongs to the field of intelligent robots, and in particular relates to a robot capable of automatically processing a submerged arc furnace charge surface. Background Art
[0002] At present, in the smelting industry, the surface treatment layer of the ore-fired furnace charge is also the combustion layer. During the combustion process of the raw materials in the furnace, they need to be processed by ramming, picking, pushing and adding materials to make the raw materials evenly distributed, expand the reaction zone, eliminate suspended materials, crush the slag, reduce crusting and surface fire, and increase the permeability of the charge to improve smelting efficiency and utilization rate.
[0003] In the submerged arc furnace smelting industry, operators typically operate from forklifts at the furnace door. The machines are very close to the furnace during surface processing operations, resulting in temperatures in front of the furnace door typically reaching 400-500°C. The temperature inside the furnace, where the material surface and equipment meet, can exceed 1300°C. This causes both the surface and internal temperatures of the equipment to rise sharply within a short period of time. This can cause the hydraulic system within existing surface processing robots to malfunction. Specifically, high hydraulic oil temperatures can change the viscosity of the oil, leading to changes in its dynamic performance, resulting in insufficient power or even complete failure. Furthermore, when the electronic control system is exposed to high temperatures, the increased temperature can cause electrical and electronic components to malfunction or even completely fail. Electronic components, in particular, are particularly susceptible to failure at high temperatures, causing control system failures and even accidents.

However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present invention.
[0037] Figure 1 This is a schematic diagram of the main structure of a specific embodiment of the electric arc furnace charge surface processing robot of the present invention.
[0038] Figure 2 This is a schematic diagram of the rear view structure of a specific embodiment of the electric arc furnace charge surface processing robot of the present invention.
[0039] like Figure 1 and Figure 2 As shown, a specific embodiment of the submerged arc furnace charge surface treatment robot of the present invention is used to treat the charge surface of a submerged arc furnace. Submerged arc furnaces, also known as electric arc furnaces or resistance furnaces, are primarily used for reducing and smelting ore to produce various products, such as ferroalloys, industrial silicon, and calcium carbide. Submerged arc furnaces consist of a furnace body, an electrode system, a charging system, and a fume exhaust system. Submerged arc furnaces utilize arc heat generated by the electrodes and the resistance heat of the charge to melt the charge and initiate a reduction reaction. Current is introduced into the furnace through the electrodes, generating an arc between the electrodes and the charge. The high temperature of the arc melts the charge. Simultaneously, the charge's own resistance also generates heat, further promoting melting and reaction. Submerged arc furnaces are primarily used in industries such as ferroalloys, industrial silicon, and calcium carbide. For example, in ferroalloy production, they can be used to produce ferrosilicon, ferromanganese, and ferrochrome. They are a key piece of equipment in industrial silicon production. In calcium carbide production, lime and coke react in the furnace to produce calcium carbide. Because they require a large amount of electrical energy to maintain high temperatures, submerged arc furnaces consume a relatively high amount of energy. Submerged arc furnaces require professional operators to monitor and adjust them to ensure the stability and safety of the production process.
[0040] The submerged arc furnace charge surface processing robot of this embodiment includes a walking mechanism 1, a slewing mechanism 2, a large arm mechanism 3, a hydraulic power component, an electrical component and a cooling device.
[0041] The slewing mechanism 2 is rotatably mounted on the traveling mechanism 1 and connected to one end of the boom mechanism 3. The slewing mechanism 2 is mounted on the traveling mechanism 1, and the boom mechanism 3 is mounted on the slewing mechanism 2. The boom mechanism 3 drives the boom forward and backward, while the slewing mechanism 2 drives the boom mechanism 3 to rotate horizontally. The traveling mechanism 1 drives the slewing mechanism 2 and the boom mechanism 3 to move relative to the submerged arc furnace. This embodiment of the submerged arc furnace charge surface treatment robot is an intelligent device specifically designed for submerged arc furnace charge surface treatment. It can quickly and accurately treat the submerged arc furnace charge surface, improving production efficiency.
[0042] The hydraulic power pack, located within the slewing mechanism 2, provides hydraulic power to the slewing mechanism 2, the traveling mechanism 1, and the boom mechanism 3. A hydraulic power pack utilizes liquid pressure to transmit and control power. It primarily comprises a hydraulic pump, a fuel tank, a control valve, and pipelines. The hydraulic pump, the core component of the hydraulic power pack, converts mechanical energy into hydraulic energy and supplies pressurized oil to the system. The fuel tank stores the hydraulic oil and also serves to dissipate heat and precipitate impurities. The control valve controls the flow direction, pressure, and volume of the hydraulic oil, enabling precise control of the actuators. Pipelines connect the various components and transport the hydraulic oil. The motor drives the hydraulic pump, which draws hydraulic oil from the fuel tank, pressurizes it, and delivers the high-pressure oil through pipelines to the control valve. The control valve controls the flow direction and pressure of the hydraulic oil based on system requirements, directing it into the actuators (such as hydraulic cylinders and hydraulic motors) to perform work. After the actuators complete their movements, the hydraulic oil flows back to the fuel tank through pipelines.
[0043] The electrical components are located within the slewing mechanism 2 and are electrically connected to the travel mechanism 1, slewing mechanism 2, boom mechanism 3, and hydraulic power pack. They receive control commands to control the movements of these mechanisms. Electrical components refer to the various components and devices used in the electrical system. They primarily include resistors, capacitors, inductors, diodes, transistors, and integrated circuits. Their primary functions include transmitting electrical energy, controlling circuits, processing signals, and providing protection.
[0044] The cooling device is disposed within the rotary mechanism 2 and is connected to the hydraulic power assembly and the electrical assembly, respectively, for cooling the hydraulic power assembly and the electrical assembly. An electric arc furnace is an industrial device used for smelting metals and generates high temperatures during operation. Electric arc furnaces typically reach temperatures of several thousand degrees Celsius. Such high temperatures enable rapid melting of ore and other charge materials, promoting chemical reactions. The high-temperature areas within the electric arc furnace are relatively concentrated near the electrodes and in the charge reaction zone, which makes the smelting process more efficient but also places high demands on the high-temperature resistance of the furnace body. To withstand high temperatures, the furnace body of an electric arc furnace is typically made of high-temperature resistant materials, such as refractory bricks and refractory concrete. The electrodes also need to have good high-temperature resistance and electrical conductivity. Surface handling robots also need to be able to withstand high temperatures, especially the hydraulic power assembly and electrical assembly mentioned above, which require the necessary protection using cooling devices to extend their service life while improving operational safety and reliability.
[0045] like Figure 1 and Figure 2 As shown, these two figures show the internal layout after the overall covering of the equipment has been removed. The main motor 5 is the robot's main motor, driving the power hydraulic pump to provide power for the entire equipment. It obtains oil from the oil tank 10 and is placed on one side of the robot. It is responsible for providing power for various movements and functions of the robot body and is controlled by the hydraulic valve group 7. The robot's electrical control box 4 is located above the main motor 5. On the other side is an independent air conditioner 6, which is responsible for ventilating and cooling the entire interior of the electrical control box 4. The independent motor 8 is independent and not controlled by the main motor 5. It cools and dissipates the oil in the oil tank 10.
[0046] Figure 3 This is a schematic diagram of the first position layout structure of the cooling device in a specific embodiment of the electric arc furnace charge surface processing robot of the present invention.
[0047] like Figure 3As shown, in this embodiment, the hydraulic power assembly includes a power hydraulic pump 12 and an oil tank 10. The power hydraulic pump 12 and the oil tank 10 are respectively arranged on both sides of the boom mechanism 3. The hydraulic pump 12 is connected to the oil tank 10 and is connected to the slewing mechanism 2, the traveling mechanism 1 and the boom mechanism 3 through a valve group. The cooling device includes a hydraulic cooling assembly. The hydraulic cooling assembly is arranged at the bottom of the oil tank 10 and arranged along the extension direction of the oil tank 10. The hydraulic cooling assembly is connected to the oil tank 10 and is used to cool the hydraulic oil in the oil tank. In this embodiment, the hydraulic cooling assembly includes a power component, a radiator component and a cooling pipeline. The cooling pipeline connects the power component and the radiator in series and is respectively connected to both ends of the oil tank 10 in the longitudinal direction. In this embodiment, one end of the cooling pipeline located at the radiator component is connected to the top of the oil tank 10, and one end of the cooling pipeline located at the power component is connected to the bottom of the oil tank. In this embodiment, the power component includes an independent motor 8 and a cooling hydraulic pump 12, with the independent motor 8 located between the radiator component and the cooling hydraulic pump 12. The radiator component includes a cooler 13 and a cooling fan 9, with the cooling fan 9 located between the cooler 13 and the independent motor 8 to dissipate heat from the main motor 5 and other components of the hydraulic power assembly. The cooling hydraulic pump in the present invention is a type of hydraulic pump that is designed for cooling. Therefore, it can be referred to as a cooling hydraulic pump or simply a hydraulic pump, and is identified and distinguished by specific figure numbers.
[0048] In this embodiment, the oil tank 10 is equipped with an independent motor 8, a hydraulic pump 12, a cooler 13, a cooling fan 9, an oil suction filter 15, an oil return filter 16, oil pipes 17, 18, and 19 to facilitate circulating heat dissipation. When motor 8 is powered on and begins operation, hydraulic pump 12 drives oil suction filter 15 via oil pipe 17 to extract hydraulic oil from the oil tank 10. The hydraulic oil then flows through oil pipe 18 to cooler 13, where it is cooled primarily by air. The cooled hydraulic oil is then returned to the oil tank 10 through oil pipe 19, passing through oil suction filter 16 and then back to the oil tank 10, achieving self-circulation. The cooling fan 9, when powered on, provides auxiliary cooling. In other embodiments, a cooling pump may also be provided internally to cool the hydraulic oil by pumping coolant through liquid cooling.
[0049] The cooler 13 is a device for reducing the temperature of the fluid. The cooler transfers the heat of the high-temperature fluid to the low-temperature fluid through heat exchange, thereby cooling the high-temperature fluid. Common cooling methods include air cooling and water cooling. The air-cooled cooler uses the flow of air to take away the heat, while the water-cooled cooler absorbs the heat through the circulation of water. It mainly includes shell and tube coolers, plate coolers, and air coolers. In this embodiment, the above forms are combined, and the cooler is further sealed and insulated according to the requirements of the working environment of the electric arc furnace, thereby improving its high temperature resistance and heat dissipation capabilities. Among them, the cooling capacity of the cooler needs to be based on the requirements of the flow rate and temperature change of the cooled fluid, and a cooler with sufficient cooling capacity should be selected. Its working pressure and temperature should be able to withstand the working pressure and temperature range of the system. In addition, it is necessary to select a suitable cooler material according to the properties of the fluid to prevent corrosion and leakage. If necessary, consider the installation method and maintenance difficulty of the cooler and select a form that is easy to install and maintain.
[0050] In high-temperature environments, the cooling fan 9 plays a crucial role. Its rotation generates airflow, accelerating air flow and removing heat generated by the equipment, thereby reducing the device's temperature. Its primary operating principle is to transfer heat from high-temperature areas to the surrounding environment through air convection and heat conduction. However, cooling fan performance deteriorates in high-temperature environments: High temperatures can increase the temperature of the cooling fan's motor, potentially reducing motor efficiency and speed, thereby impacting heat dissipation. High temperatures can also accelerate the aging of cooling fan components, such as bearing wear and lubricant drying, shortening the fan's service life. In high-temperature environments, the cooling fan may malfunction, such as motor burnout and blade deformation, reducing system reliability. In the present invention, high-temperature-resistant materials are selected for the cooling fan's housing, blades, and motor, such as aluminum alloy, stainless steel, and ceramic, to enhance the fan's high-temperature resistance. The present invention also optimizes the cooling fan's structural design to improve its heat dissipation efficiency and air flow. These include increasing the number of blades, optimizing blade shape, and increasing motor speed. In other embodiments, additional cooling measures can be implemented, such as installing heat sinks around the cooling fan or using a coolant, to reduce the fan's operating temperature.
[0051] In high-temperature environments, the suction filter 15 and return filter 16 face a series of unique challenges. Suction filters are typically installed in the suction line of a hydraulic system. Their primary function is to filter impurities from the hydraulic oil, preventing them from entering the hydraulic system and thus protecting the hydraulic components. As the hydraulic oil passes through the suction filter, impurities are intercepted by the filter element, allowing clean hydraulic oil to enter the hydraulic system. Filtering efficiency decreases in high-temperature environments. High temperatures reduce the viscosity of the hydraulic oil and increase its fluidity, which can make it easier for impurities to pass through the filter element, reducing filtration efficiency. High temperatures also accelerate aging and damage to the filter element, shortening its service life. For example, high temperatures can cause the filter material to become brittle, deform, or even crack. High temperatures can also age and harden the seals of the suction filter, resulting in poor sealing performance and leakage. While high temperatures reduce the viscosity of the hydraulic oil, they also increase the resistance of the filter element. This is because high temperatures reduce the pores in the filter element, increasing the resistance to hydraulic oil passing through the filter element. The present invention selects high-temperature-resistant filter element materials: In high-temperature environments, filter elements should be made of high-temperature-resistant materials such as fiberglass and wire mesh. These materials have excellent high-temperature resistance and can maintain good filtration performance even at high temperatures. In this embodiment, a cooling device, including a cooling fan 9 and a cooler 13, is installed near the oil suction filter to reduce the temperature of the hydraulic oil, thereby improving filtration efficiency and extending the life of the filter element. In this embodiment, it is also sealed and insulated to minimize the impact of radiant heat from the submerged arc furnace, as described below.
[0052] Figure 4 This is a schematic diagram of the third position layout structure of the cooling device in a specific embodiment of the electric arc furnace charge surface processing robot of the present invention.
[0053] Figure 5 This is a schematic diagram of the layout structure of the cooling device at the third position from another perspective in a specific embodiment of the electric arc furnace charge surface processing robot of the present invention.
[0054] like Figure 4 and Figure 5 As shown, in this embodiment, the cooling device includes an electrical cooling component, which is arranged on the side of the power hydraulic pump away from the boom mechanism 3. The electrical cooling component is wrapped around the outside of the electrical component to isolate heat and cool the electrical component. In this embodiment, the electrical cooling component includes a cooling box and a cooler. A cooling space is formed in the cooling box to accommodate the electrical component; the cooler is connected to one end of the cooling box through an air inlet pipe and an air return pipe to introduce cooling gas into the cooling space and recover it. In this embodiment, a cooling air duct is provided in the cooling box, and is extended along the length direction of the cooling box, and is stacked and continuously arranged in the height direction. The cooling air duct has an air outlet toward the side of the electrical component, and the two ends of the cooling air duct are respectively connected to the air inlet pipe and the air return pipe.
[0055] In this embodiment, the heat dissipation of the electric control cabinet 4 is achieved by adding an external independent air conditioner 6. The independent air conditioner is provided with four ventilation openings, namely, an internal circulation cold air inlet 45, an internal circulation cold air outlet 46, an external circulation hot air outlet 47, and an external circulation air inlet 48. The air is communicated with the interior of the electric control cabinet 4 through an air outlet pipe 43 and an air inlet pipe 44, thereby reducing the internal temperature of the electric control cabinet.
[0056] In this embodiment, the air conditioner 6 is a cooling device specifically designed for the electrical control cabinet 4. Through a compression-refrigeration cycle, the air conditioner absorbs heat from the electrical control cabinet and discharges it to the external environment, thereby reducing the temperature within the cabinet. Its operating process primarily consists of four stages: compression, condensation, throttling, and evaporation. In the compression stage, the refrigerant is compressed into a high-temperature, high-pressure gas. In the condensation stage, the high-temperature, high-pressure gas dissipates heat through the condenser, becoming a high-temperature, high-pressure liquid. In the throttling stage, the high-temperature, high-pressure liquid is reduced in pressure by the throttling device, becoming a low-temperature, low-pressure liquid. In the evaporation stage, the low-temperature, low-pressure liquid absorbs heat from the electrical control cabinet in the evaporator, becoming a low-temperature, low-pressure gas. This gas is then drawn into the compressor, beginning the next cycle. The air conditioner 6 precisely controls the temperature within the electrical control cabinet, maintaining it within a stable range and ensuring the normal operation of the electrical control equipment. Compared to traditional heat dissipation methods such as fans and natural cooling, the electrical control cabinet cooling air conditioner offers higher heat dissipation efficiency and can rapidly reduce the temperature within the cabinet. The air conditioner 6 also prevents dust, moisture, corrosive gases, and other gases from entering the cabinet, protecting the electrical control equipment.
[0057] Figure 6 This is a schematic diagram of the second position layout structure of the cooling device in a specific embodiment of the electric arc furnace charge surface processing robot of the present invention.
[0058] Figure 7 for Figure 6 Schematic diagram of the structure of the middle insulation board.
[0059] like Figure 6 and Figure 7 As shown, in this embodiment, the ore-fired furnace charge surface processing robot also includes a sealing component, part of which is wrapped around the outside of the rotary mechanism 2, and is used to partially cover the hydraulic power component and the electrical component inside; the side of the walking mechanism 1 located below the large arm mechanism 3 is the insulation end, and part of the sealing component is arranged on the insulation end. In this embodiment, the sealing component includes a plurality of insulation boards, and the insulation boards are hollow structures, and insulation materials are arranged in the hollow structures. In this embodiment, the insulation boards are made of stainless steel and are connected to the rotary mechanism 2 and the walking mechanism 1 in a detachable manner; the insulation material is rock wool, which is clamped in the hollow structure of the insulation boards.
[0060] In this embodiment, the hollow stainless steel structure consists of two layers of stainless steel plates with a hollow space in between. This structural design provides the material with excellent thermal insulation properties. The high strength and corrosion resistance of stainless steel ensure its longevity and stability. When the hollow space is filled with air, air is a poor conductor of heat, effectively preventing heat transfer. As heat passes through the stainless steel plates and the air layer, the low thermal conductivity of air significantly reduces the rate of heat transfer, thus achieving a thermal insulation effect. Furthermore, the stainless steel surface has a certain reflective capacity, reflecting some heat and reducing heat absorption. This reflection further enhances the material's thermal insulation properties. This structure effectively blocks heat transfer and reduces energy consumption. In high-temperature environments, the stainless steel hollow insulation material can maintain a stable temperature within the interior, providing a comfortable working environment for the robot. Stainless steel's excellent corrosion resistance allows for long-term use in a variety of harsh environments. Whether in humid, acidic, alkaline, or high-temperature environments, the stainless steel hollow insulation material maintains its stable performance and is unaffected by corrosion. Stainless steel also has high strength and can withstand certain pressures and impacts. This makes stainless steel hollow insulation material resistant to deformation and damage during use, ensuring its long-term effectiveness. The smooth, shiny surface of stainless steel creates a beautiful decorative effect. Furthermore, the durability of stainless steel ensures that this insulation material retains its beauty over time, resisting fading and aging. Stainless steel hollow insulation material contains no harmful substances and is harmless to the environment and human health. It also does not release any toxic gases during use, complying with environmental protection requirements.
[0061] In this embodiment, the electrical control cabinet 4 is enclosed therein, and the main structure of the robot, including other electrical components and hydraulic power components, is also enclosed as necessary in this embodiment. It includes the first heat insulation board 22, the second heat insulation board 23, the third heat insulation board 24, the fourth heat insulation board 25 and the fifth heat insulation board 26. For specific locations, refer to Figure 6 As shown in .
[0062] like Figure 7As shown, in this embodiment, the third insulation board 24 is dissected from its center. It features a hollow structure to reduce weight and is filled with rock wool for insulation. Rock wool is an inorganic fiber material made from basalt through high-temperature melting. Its fibers are slender and flexible, and its low shot content results in a low thermal conductivity, providing excellent insulation, effectively reducing heat transfer and lowering energy consumption. Rock wool is a non-combustible building material with the highest fire rating, A1, and is heat-resistant, with a melting point exceeding 1000°C. In a fire, it does not expand, contract, or deform, nor does it produce smoke, burning droplets, or debris. It also does not release harmful substances or gases, effectively preventing the spread of fire and providing valuable time for evacuation and fire rescue efforts. Testing has shown that rock wool does not contain environmentally harmful substances such as asbestos, CFCs (chlorofluorocarbons), HFCs (hydrofluorocarbons), or HCFCs (hydrochlorofluorocarbons). It is not susceptible to corrosion, mold, or bacteria, and has been certified as non-carcinogenic by the International Agency for Research on Cancer.

[0064] In the present invention, the hydraulic power components and electrical components are cooled by the cooling device, which can improve the high temperature resistance, thereby improving the reliability of the robot in the smelting material surface processing of the electric arc furnace, thereby improving the overall operation safety and economy, which has a very great progressive significance.
