Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, and in particular to a mobile aluminum ladle baking device. Background Technology

[0002] In the aluminum smelting and casting process, the aluminum ladle is a key piece of equipment used to hold and transport high-temperature molten aluminum. The aluminum ladle needs to be fully preheated and baked before use to avoid defects such as porosity and inclusions caused by a sudden drop in temperature when the molten aluminum is poured into the cold ladle.

[0003] Currently, the preheating and baking of molten aluminum ladles mainly employs fixed ladle bakers or manual baking with gas-fired torches. Fixed ladle bakers are typically installed at fixed workstations, requiring the molten aluminum ladles to be hoisted to the baker for baking, resulting in a cumbersome and inefficient process. Manual baking with gas-fired torches relies on manual operation, leading to uneven baking and significant safety hazards. As the aluminum smelting industry demands higher production efficiency and safety, there is a need to design a mobile ladle baking device to address the aforementioned problems.

[0007] Preferably, the air supply unit includes a blower, the input end of which is fixedly equipped with a filter, the output end of which is connected to an air pipe, and the outside of the air pipe is equipped with a second air pressure switch and a butterfly valve.

[0008] Preferably, the igniter unit includes an igniter cover, and three connecting chains are equidistantly hung on the upper part of the igniter cover. The upper ends of the connecting chains are fixedly connected to the bottom of the front fixing frame by bolts. A gas connection pipe is provided on the upper right side of the igniter cover, and a second adapter hose is fixedly provided between the gas connection pipe and the front end of the second gas pipe.

[0011] Preferably, limit switches are fixedly connected to the upper and lower rear ends of the lifting frame by bolts; A support rod is welded to the bottom rear side of the lifting frame, and the bottom end of the support rod is welded to the upper part of the base frame.

[0012] In summary, the present invention provides a mobile aluminum ladle baking device, which has the following beneficial effects: The device, consisting of a base frame, electric forklift, traveling unit, and support unit, enables flexible movement, rapid positioning, and stable support within the work area. The base frame, as the core load-bearing foundation, firmly integrates all functional units, ensuring overall structural rigidity and providing strong traction for the electric forklift. Combined with the omnidirectional wheels at the bottom of the welded frame in the traveling unit, the device can achieve 360° flexible turning and smooth movement, easily navigating between multiple aluminum ladle workstations. Upon reaching the target position, rotating the handwheel of the support unit drives the threaded rod to precisely rise and fall along the threaded sleeve, ensuring a tight fit between the support pad and the ground, forming a four-point stable support. This effectively resists vibration and external impact during the ladle baking process, preventing device displacement and eliminating the need for fixed installations that restrict flexible deployment. It also eliminates the need for separate ladle baking equipment for each aluminum ladle, significantly reducing equipment procurement and maintenance costs. Furthermore, it reduces the area occupied by fixed equipment in the work area, allowing for more flexible workspace layout. The lifting unit enables precise lifting of the installation unit, igniter unit, gas control unit, and air supply unit. The drive motor outputs power, which is efficiently transmitted through the meshing of the first and second bevel gears, converting horizontal power into vertical power. This drives the lead screw to rotate smoothly. The high-precision threaded connection between the lifting block and the lead screw further converts the rotational motion into linear lifting motion, achieving millimeter-level height adjustment. During lifting, the engaging protrusions of the lifting frame and the engaging grooves of the connecting frame form multi-directional guiding constraints, effectively limiting horizontal displacement and preventing tilting or offset of the installation unit, ensuring stable lifting. Limit switches at the upper and lower ends of the rear of the lifting frame monitor the lifting limit positions of the connecting frame in real time. Overtravel triggers immediate shutdown protection to prevent component collision damage. This avoids the limitations of fixed height and poor adaptability of traditional baking devices, allowing for flexible adaptation to baking needs of aluminum ladles of different heights and volumes, significantly improving the adaptability and stability of baking operations. Through the gas delivery unit, gas control unit, air supply unit, and igniter unit, the system achieves integrated functions of safe gas delivery, precise gas-air mixing ratio, and real-time control of baking temperature. Gas is delivered via the first gas pipeline. The air-fuel ratio valve precisely adjusts the gas-air mixing ratio according to the needs of each baking stage. The pressure transmitter monitors the gas pressure in real time and feeds it back to the control box to ensure pressure stability. After the gas enters the second gas pipeline, the first air pressure switch, leak detector, and check valve form a triple safety protection system: automatic gas shut-off in case of overpressure, immediate leak alarm, and prevention of gas backflow and backfire. In the air supply unit, the blower delivers filtered air into the air pipe, the butterfly valve precisely regulates the air flow, and the second air pressure switch ensures stable air pressure. The mixed gas and air are fully combusted in the igniter cover. Thermocouples collect the baking temperature in real time and feed it back to the control box, dynamically adjusting the gas flow and air supply to achieve closed-loop temperature control. This avoids the technical problems of high gas leakage risk, incomplete combustion, and low temperature control accuracy in the baking device. It not only eliminates safety hazards such as gas leakage and backfire through multiple safety protections, but also improves the gas combustion efficiency through precise mixing.

[0014] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below. Example

[0015] Please see Figures 1-9 As shown, the present invention provides a technical solution: a mobile aluminum ladle baking device, including a base frame 1, a lifting unit 2 and several support frames 4 fixedly installed on the upper end of the base frame 1, an installation unit 3 installed on the front side of the lifting unit 2, an igniter unit 8 fixedly connected to the bottom front side of the installation unit 3, a gas delivery unit 5 installed on the upper part of the support frame 4, a gas control unit 6 installed on the upper right side of the installation unit 3, an air supply unit 7 installed on the upper left side of the installation unit 3, support units 9 fixedly installed on the left and right rear sides of the base frame 1, an electric forklift 10 installed on the rear side of the base frame 1, and a walking unit 11 fixedly connected to the front side of the base frame 1; The lifting unit 2 is used to control the lifting of the installation unit 3, the gas control unit 6, the air supply unit 7, and the igniter unit 8; The support frame 4 is used to fix and support the gas delivery unit 5, and the mounting unit 3 is used to fix and support the gas control unit 6 and the air supply unit 7. The gas delivery unit 5 and the gas control unit 6 are used to deliver and control gas to the igniter unit 8, and the air supply unit 7 is used to deliver and control air to the igniter unit 8. The electric forklift 10 and the traveling unit 11 are used to move the chassis 1 and its upper structure, and the support unit 9 is used to support the ground after the chassis 1 is moved. The mounting unit 3 includes a connecting frame 301. A rear fixing frame 302 is fixedly connected to the rear side of the connecting frame 301 by bolts. A middle fixing frame 303 is welded to the front side of the connecting frame 301, and a front fixing frame 304 is welded to the front side of the middle fixing frame 303.

[0016] Please see Figures 1-4 As shown, the lifting unit 2 includes a lifting frame 201 welded to the upper part of the base frame 1. A drive motor 202 is fixedly installed on the rear bottom side of the lifting frame 201. A first bevel gear 203 is fixedly connected to the rotating shaft of the drive motor 202. A lead screw 204 is rotatably connected inside the lifting frame 201. A second bevel gear 205 is fixedly connected to the bottom of the lead screw 204. The first bevel gear 203 and the second bevel gear 205 mesh. The drive motor 202 drives the first bevel gear 203 and the second bevel gear 205 to mesh and transmit power, realizing a 90° efficient conversion of the power direction. The transmission process is smooth and without jamming, with low power loss. The compact gear transmission structure is adapted to the limited installation space inside the lifting frame 201, which can ensure that the lead screw 204 obtains a continuous and stable driving force, providing reliable power support for the lifting and lowering actions of the installation unit 3 and the gas control unit 6, air supply unit 7, and igniter unit 8. At the same time, the transmission accuracy of the gear meshing is high, ensuring the synchronization of the lifting and lowering actions. A lifting block 305 is welded to the inner side of the connecting frame 301. The rear side of the lifting block 305 is threaded to the outer side of the lead screw 204. The threaded connection structure between the lifting block 305 and the lead screw 204 converts the rotational motion of the lead screw 204 into the linear lifting motion of the lifting block 305. This allows the connecting frame 301 to drive the installation unit 3 and each functional unit to stay stably at any target height, avoiding accidental settlement due to vibration or external force during the baking process, and ensuring operational safety and the stability of the baking effect. The lifting frame 201 has locking protrusions 206 welded on both the left and right sides and the front and rear ends. The connecting frame 301 has locking grooves 306 welded on both the left and right sides and the front and rear ends inside. The locking protrusions 206 are locked to the inner side of the corresponding locking grooves 306. The locking protrusions 206 and the locking grooves 306 form a multi-directional guiding and cooperating structure, which provides precise guidance for the lifting and lowering movement of the connecting frame 301, strictly limits its horizontal displacement, and effectively prevents unstable phenomena such as tilting and deviation during the lifting and lowering process.

[0017] Please see Figures 1-5As shown, the gas delivery unit 5 includes a first gas pipeline 501 bolted to the upper part of the rear fixed frame 302. The first gas pipeline 501 is mounted on the upper part of several support frames 4. An air-fuel proportional valve 502 and a pressure transmitter 503 are installed on the outside of the first gas pipeline 501. The dual fixing method of bolt fixing and mounting on the support frames 4 ensures that the first gas pipeline 501 forms a stable connection with the rear fixed frame 302 and the support frames 4, which can effectively resist the vibration and impact during the movement and operation of the device and prevent the pipeline from loosening. The air-fuel proportional valve 502 can accurately adjust the mixing ratio of gas and air according to the baking requirements, ensuring that the gas is fully combusted and improving the heat utilization rate and baking efficiency. The pressure transmitter 503 monitors the gas pressure in the first gas pipeline 501 in real time and feeds back the pressure signal to the control box 12, providing accurate data support for overpressure warning and dynamic pressure adjustment, and avoiding the risk of gas overpressure leakage from the source. The gas control unit 6 includes a second gas pipeline 601, which is mounted on the right side of the central fixed frame 303. A first air pressure switch 602, a flow regulator 603, a leak detector 604, and a check valve 605 are installed on the outer side of the second gas pipeline 601. A first adapter hose 17 is installed on the rear side of the second gas pipeline 601 and the front side of the first gas pipeline 501. The first air pressure switch 602, the leak detector 604, and the check valve 605 form a triple safety protection: the first air pressure switch 602 monitors the pressure of the second gas pipeline 601 and automatically cuts off the pressure when overpressure occurs. Gas source cut-off; Leak detector 604 quickly captures gas leak signals and promptly triggers alarms or gas shut-off actions; Check valve 605 prevents gas backflow from causing backfire or negative pressure in the pipeline, significantly reducing safety hazards; Flow regulator 603 can precisely fine-tune the gas delivery volume to adapt to the heat requirements of different stages such as baking preheating and heat preservation; The first adapter hose 17 has good flexibility, extension and bending performance, and can flexibly deform with the lifting and lowering action of the installation unit 3, avoiding the pulling and breaking of the second gas pipeline 601 and the first gas pipeline 501 due to relative movement, ensuring the continuity and sealing of gas delivery.

[0018] Please see Figures 1-5As shown, the air supply unit 7 includes a blower 701. A filter 702 is fixedly installed at the input end of the blower 701, and an air pipe 703 is connected to the output end of the blower 701. A second air pressure switch 704 and a butterfly valve 705 are installed on the outside of the air pipe 703. The filter 702 can efficiently filter dust, particulate matter and other impurities in the air, preventing impurities from entering the air pipe 703, butterfly valve 705 or combustion system. This ensures complete combustion of the gas and prevents impurities from accumulating and clogging components, extending the service life of components such as the blower 701 and air pipe 703. The second air pressure switch 704 monitors the air delivery pressure in real time to ensure that the air supply and pressure are stably matched to the gas combustion demand, avoiding the impact of air pressure fluctuations on the combustion effect. The butterfly valve 705 is easy to adjust and has high flow control accuracy. It can quickly respond to changes in the air volume demand for gas combustion, ensuring complete combustion of the gas, reducing the emission of harmful gases such as carbon monoxide, and improving energy utilization and the safety of the working environment.

[0019] Please see Figures 1-6 As shown, the igniter unit 8 includes an igniter cover 801. Three connecting chains 802 are equidistantly hung on the upper part of the igniter cover 801. The upper ends of the connecting chains 802 are fixed to the bottom of the front fixing frame 304 by bolts. The three equidistantly distributed connecting chains 802 achieve balanced suspension of the igniter cover 801. The bolt connection method facilitates installation, disassembly, maintenance, and replacement. The flexibility of the connecting chains 802 can buffer the impact of combustion vibration and slight displacement of the device during the baking process, avoiding structural stress concentration and damage to the igniter cover 801 caused by rigid connection. At the same time, the length of the connecting chains 802 can be finely adjusted to make the igniter cover 801 fit precisely with the opening of the aluminum ladle, reducing heat loss and improving baking efficiency and temperature uniformity. A gas connection pipe 803 is provided on the upper right side of the igniter cover 801. A second adapter hose 18 is fixedly installed between the gas connection pipe 803 and the front end of the second gas pipe 601. An air supply connection pipe 804 is provided on the upper left side of the igniter cover 801. A third adapter hose 19 is fixedly installed between the air supply connection pipe 804 and the front end of the air supply unit 7. The second adapter hose 18 and the third adapter hose 19 are made of flexible material that is resistant to high and low temperatures and corrosion. They can flexibly deform with the lifting and fine-tuning movements of the igniter unit 8, effectively avoiding the risk of twisting and pulling breakage caused by the rigid connection of the gas connection pipe 803 and the air supply connection pipe 804. At the same time, the flexible hose has excellent sealing performance, ensuring that there is no leakage in the gas and air delivery channels, ensuring a stable power supply to the combustion system, and avoiding interruption of the baking operation due to pipe connection problems. A thermocouple 805 and a flue 806 are also installed on the upper front side of the igniter cover 801. The thermocouple 805 has the characteristics of high temperature detection accuracy and fast response speed. It can collect the baking temperature data of the aluminum ladle inside the igniter cover 801 in real time and feed the signal back to the control box 12 to realize closed-loop precise control of the baking temperature, avoiding damage to the aluminum ladle due to overheating or insufficient baking due to insufficient temperature. The flue 806 can quickly discharge the flue gas and exhaust gas generated by combustion, improve the working environment, avoid the accumulation of flue gas affecting combustion efficiency and operator health, and at the same time reduce the corrosion of the igniter cover 801 and surrounding components by the flue gas, extending the overall service life of the equipment.

[0020] Please see Figure 2 and Figure 8 As shown, the support unit 9 includes two threaded sleeves 901 welded to the left and right sides of the rear end of the base frame 1. Each threaded sleeve 901 has a threaded rod 902 threadedly connected inside. The bottom end of each threaded rod 902 is threadedly connected to a support pad 903. Each threaded rod 902 has a handwheel 904 at its upper end. The threaded connection structure between the threaded sleeve 901 and the threaded rod 902 provides smooth transmission and high adjustment precision. Operators can easily raise and lower the threaded rod 902 by turning the handwheel 904, making operation convenient and labor-saving, and allowing for quick adaptation to work sites with varying flatness. The support pad 903 is made of wear-resistant and non-slip material, increasing the contact area with the ground, effectively distributing the weight of the base frame 1 and all upper structures, significantly improving the support stability and anti-tipping ability of the device, preventing displacement of the device due to vibration during the baking process, and ensuring operational safety and baking effect. The traveling unit 11 includes a welded frame 1101 welded to the front of the base frame 1. The bottom left and right sides of the welded frame 1101 are equipped with universal wheels 1102. The welded frame 1101 is made of high-strength steel, with high structural strength and strong load-bearing capacity, providing a stable installation foundation for the universal wheels 1102 and bearing the overall weight of the device. The universal wheels 1102 are flexible in steering and have low rolling resistance. With the help of the electric forklift 10 on the rear of the base frame 1, the device can move, turn and position quickly in the work area, greatly improving the operational flexibility and mobility of the device, adapting to the operational needs of alternating baking of multiple aluminum ladles and improving equipment utilization.

[0021] Please see Figure 2 and Figure 9 As shown, a control box 12 is fixed to the upper left side of the base frame 1 by bolts; Several support frames 4 and the central fixed frame 303 are each equipped with several fixed slots 16. Each fixed slot 16 contains a fixed clamp 13, which is a U-shaped bend with threaded sections at both ends. Nuts are threaded onto each threaded section. The U-shaped fixed clamp 13 is adaptable to the installation and fixing of the first gas pipeline 501, the second gas pipeline 601, and the air pipeline 703 with different pipe diameters, and has strong versatility. Through the locking fit between the threaded section and the nut, the pipeline can be quickly fixed and disassembled, which is convenient and efficient and facilitates later maintenance and repair. The cooperation between the fixed clamp 13 and the fixed slot 16 can effectively limit the axial and radial displacement and shaking of the pipeline during the movement, operation, and vibration of the device, and prevent loosening and leakage at the pipeline connection, further ensuring the safety and stability of gas and air transportation.

[0022] Please see Figure 2 and Figure 7 As shown, limit switches 14 are fixedly connected to the upper and lower ends of the rear side of the lifting frame 201 by bolts. These switches detect the upper and lower limit positions of the connecting frame 301. When the lifting block 305 drives the connecting frame 301 to the limit position, the connecting frame 301 touches the limit switch 14. The limit switch 14 immediately sends a signal to the control box 12 to control the drive motor 202 to stop running. This achieves mechanical and electrical dual limit protection for the lifting stroke, preventing over-travel from causing the connecting frame 301 to collide with or be damaged by the lifting frame 201 or other components, thus ensuring the operational safety and service life of the lifting unit 2. A support rod 15 is welded to the bottom rear side of the lifting frame 201. The bottom end of the support rod 15 is welded to the upper part of the base frame 1. The support rod 15 adopts a triangular support structure design, with one end welded to the bottom of the lifting frame 201 and the other end welded to the upper part of the base frame 1. This effectively enhances the connection rigidity and structural stability between the lifting frame 201 and the base frame 1, and can disperse the longitudinal load and vibration stress borne by the lifting frame 201. This prevents the lifting frame 201 from deforming or tilting due to load concentration during long-term use, ensuring the operating accuracy and long-term stability and reliability of the lifting unit 2, and extending the overall service life of the device.

[0023] The implementation principle of this application embodiment is as follows: First, when moving the base frame 1, the electric forklift 10 on the rear side cooperates with the universal travel wheel 1102 at the bottom of the welded frame 1101 of the front travel unit 11 to drive the base frame 1 and all its upper structures to move flexibly. After reaching the target position next to the aluminum ladle, the rotating handwheel 904 of the support unit 9 is rotated to drive the threaded rod 902 to rotate downward along the threaded sleeve 901, so that the support pad 903 is tightly attached to the ground, thereby achieving stable support of the base frame 1. Then, the control box 12 is started, and the lifting unit 2 starts to work. The shaft of the drive motor 202 drives the first bevel gear 203 to rotate. The first bevel gear 203 meshes with the second bevel gear 205 at the bottom of the lead screw 204, causing the lead screw 204 to rotate inside the lifting frame 201. The lifting block 305 on the inner side of the connecting frame 301 is threadedly connected to the lead screw 204. When the lead screw 204 rotates, it drives the installation unit 3 to lift as a whole. At the same time, the locking groove 306 slides on the outside of the locking protrusion 206 to ensure that the lifting process is smooth and without deviation. The lifting limit position of the connecting frame 301 is detected in real time through the two limit switches 14 on the upper and lower sides. Secondly, the first gas pipeline 501 of the gas delivery unit 5 is fixed to the upper part of the rear fixing frame 302 by bolts and mounted on several support frames 4. The U-shaped fixing clamps 13 in the fixing slots 16 of the support frame 4 are locked by the threaded sections and nuts at both ends to achieve a stable fixation of the first gas pipeline 501. The air-fuel ratio valve 502 on the first gas pipeline 501 adjusts the mixing ratio of gas and air. The pressure transmitter 503 monitors the gas pressure in real time and feeds it back to the control box 12. The gas is delivered through the first gas pipeline 501 and the first adapter hose 17. The second gas pipeline 601 to the gas control unit 6 is mounted on the right side of the middle fixing frame 303. The fixing clamp 13 in the fixing slot 16 of the middle fixing frame 303 fixes it. The first air pressure switch 602 on the second gas pipeline 601 monitors the pipeline pressure. The flow regulator 603 adjusts the gas delivery flow. The leak detector 604 detects gas leaks and triggers an alarm or gas shut-off. The check valve 605 prevents gas backflow. Finally, the gas is delivered to the gas connection pipeline 803 of the igniter cover 801 through the second adapter hose 18. When the air supply unit 7 is working, the filter 702 at the input end of the blower 701 filters impurities in the air, and the purified air is delivered through the air pipe 703. The second air pressure switch 704 on the air pipe 703 monitors the air pressure, and the butterfly valve 705 regulates the air flow. The air is delivered through the third adapter hose 19 to the air supply connection pipe 804 of the igniter cover 801 and mixed with the gas in the igniter cover 801. The igniter cover 801 is further suspended and fixed to the bottom of the front fixing frame 304 by three connecting chains 802, covering the aluminum molten ladle. The mixed gas and air are ignited and burned to preheat the aluminum molten ladle. The thermocouple 805 on the top of the igniter cover 801 detects the ladle temperature in real time and feeds it back to the control box 12 for precise temperature control.
