Description

Technical Field

[0001] This utility model relates to the technical field of aluminum melting furnaces, and in particular to an aluminum melting furnace operation monitoring device. Background Technology

[0002] An aluminum melting furnace is an industrial heating device specifically designed for melting aluminum and aluminum alloys. It is widely used in aluminum product processing, casting, and recycled aluminum production. This equipment typically uses gas, oil, or electric heating. Furnace designs include various types such as reverberatory furnaces, induction furnaces, and crucible furnaces, featuring high efficiency, energy saving, precise temperature control, and rapid melting speed. Modern aluminum melting furnaces are often equipped with advanced combustion systems, waste gas treatment devices, and automated control systems to improve thermal efficiency (up to 50% or more) and reduce environmental pollution. Their operating temperature is generally controlled within the range of 700-800℃. They can process aluminum ingots, aluminum chips, or scrap aluminum of different specifications according to production needs, with daily processing capacities ranging from several tons to tens of tons. They are a key thermal equipment in the aluminum industry chain.

[0003] During the operation of aluminum melting furnaces, monitoring devices are typically required to monitor the operating environment and smelting process in real time. However, existing monitoring devices generally lack effective protective mechanisms, resulting in cameras being directly exposed to the high-temperature, high-dust working environment. Because aluminum ash, smoke, and high-temperature splashes are easily generated during the operation of aluminum melting furnaces, these impurities easily adhere to the camera lenses, affecting not only the clarity of the monitored images but also potentially causing poor heat dissipation or damage to optical components due to long-term accumulation. This reduces the reliability and lifespan of the monitoring system. Furthermore, the lack of protection also accelerates the aging of the electronic components and sealing performance of cameras under the high-temperature radiation and corrosive gases inside the furnace, further affecting the accuracy and continuity of monitoring data.

[0016] (1) In this utility model, the protective cover can effectively block aluminum ash, smoke and high-temperature splashes generated during the operation of the aluminum melting furnace, prevent pollutants from adhering to the camera lens, thereby avoiding poor heat dissipation or damage to optical components caused by long-term dust accumulation, and improving the service life of the camera.

[0027] Please refer to Figure 1-4A monitoring device for the operation of an aluminum melting furnace includes a mounting shell 1. A shaft seat is fixedly installed at the middle position of the lower top surface of the mounting shell 1, and a rotating rod 12 is installed in the shaft seat. One end of the rotating rod 12 passes through the bottom surface of the mounting shell 1 and is fixedly connected to a camera 11. A protective cover 7 is fixedly installed on the bottom surface of the mounting shell 1 outside the camera 11. A first motor 4 is fixedly installed on one side of the upper bottom surface of the mounting shell 1, and a shaft seat is fixedly installed on one side of the bottom surface of the mounting shell 1. A reciprocating lead screw 10 is fixedly installed at the output end of the first motor 4 and in the shaft seat, and a moving block 8 is provided on the reciprocating lead screw 10. A cleaning frame 5 is fixedly connected between the moving blocks 8 through the protective cover 7. Brush bristles 6 are fixedly installed around the inner wall of the cleaning frame 5. One end of the reciprocating screw 10 is fixedly connected to a synchronous wheel 16, and a synchronous belt 17 is installed between the synchronous wheels 16. The bottom surface of the mounting shell 1 is connected to the moving blocks 8 on both sides, and the limit rods 9 are fixedly connected. The protective cover 7 can effectively block the aluminum ash, smoke and high-temperature splashes generated during the operation of the aluminum melting furnace, and prevent pollutants from adhering to the lens of the camera 11, thereby avoiding poor heat dissipation or damage to optical components caused by long-term dust accumulation, and improving the service life of the camera 11. When the monitoring device is working, the camera 11 can observe the internal working conditions of the aluminum melting furnace in real time, so that the staff can keep abreast of the melting status.

[0028] Please refer to Figure 1 and Figure 2 A second motor 14 is fixedly installed on one side of the lower top surface of the mounting housing 1, and a second gear 15 is fixedly connected to the output end of the second motor 14. The second gear 15 meshes with a first gear 13 fixedly installed on the rotating rod 12. The number of teeth of the first gear 13 corresponds to the number of teeth of the second gear 15, which can maintain the normal rotation of the first gear 13 and the second gear 15. The second motor 14, which is set on the lower top surface of the mounting housing 1, is started to drive the second gear 15 connected to its output shaft to rotate. The second gear 15 meshes with the first gear 13 fixed on the rotating rod 12, driving the rotating rod 12 and the camera 11 installed at its bottom to rotate synchronously, thereby realizing the precise adjustment of the shooting angle of the camera 11 and optimizing the adjustable range of the monitoring field of view.

[0029] Please refer to Figure 1 , Figure 2 and Figure 4The cleaning frame 5 and the protective cover 7 are circular structures, with the diameter of the cleaning frame 5 being larger than that of the protective cover 7. The cleaning frame 5 matches the protective cover 7, and the bristles 6 abut against the protective cover 7. When the first motor 4 on the upper surface of the bottom of the mounting housing 1 is started, the first motor 4 drives the reciprocating lead screw 10 to rotate, and drives another reciprocating lead screw 10 to rotate synchronously through the synchronous wheel 16 and the synchronous belt 17. Under the constraint of the limit rod 9, the moving block 8 moves up and down along the reciprocating lead screw 10, while simultaneously moving the cleaning frame 5. The bristles 6 on the inner wall of the cleaning frame 5 can periodically clean the outer surface of the protective cover 7 to ensure its light transmittance and avoid dust residue affecting the clarity of the monitoring image, thereby maintaining the stable operation of the camera 11. This not only improves the reliability of the monitoring device but also reduces the frequency of manual maintenance, making it suitable for high-temperature and high-dust working environments in aluminum melting furnaces.

[0030] Please refer to Figure 1 The movable block 8 is slidably connected to the limiting rod 9. The limiting rod 9 can limit the movable block 8, allowing it to move up and down on the reciprocating screw 10, thereby driving the cleaning frame 5 to move up and down, facilitating automatic cleaning of dust on the protective cover 7.

[0031] Please refer to Figure 1 The bottom surface of the mounting shell 1 is provided with a first heat dissipation vent on both sides, and the two sides of the mounting shell 1 are provided with a second heat dissipation vent. The use of the first and second heat dissipation vents can maintain the normal heat dissipation of the equipment.

[0032] Please refer to Figure 1 Mounting blocks 2 are fixedly connected to both sides of the mounting shell 1, and mounting holes 3 are opened through the middle of the top surface of the mounting blocks 2. The device can be installed and fixed by passing the mounting nail through the mounting holes 3.

[0033] Please refer to Figure 1 , Figure 3 and Figure 4 The protective cover 7 is matched with the camera 11. The use of the protective cover 7 can effectively block the aluminum ash, smoke and dust and high temperature splashes generated during the operation of the aluminum melting furnace, and prevent pollutants from adhering to the lens of the camera 11, thereby avoiding poor heat dissipation of the equipment or damage to optical components due to long-term dust accumulation. The protective cover 7 is made of high temperature resistant transparent tempered glass.

[0034] The control switch control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. Since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0035] This system is built using the Youren Cloud USR-M300 and a series of sensors and intermediate relays. The M300's built-in red-noed programming logic is used to design time calculation logic. It reads sensor signals to calculate the time of corresponding operations and reports the data to the cloud platform via a set reporting mode. The Youren Cloud platform allows for remote data viewing and monitoring, thus enabling the monitoring of the aluminum melting circuit operation time. The time calculation logic is as follows: First, the device receives a signal to trigger the recording of the current time. Second, the device receives another signal to obtain a new time. The time difference between the two times is calculated to obtain the time result from the first signal to the second signal.

[0036] Working principle:

[0037] When in use, the device is fixedly installed in the designated position. After installation, the protective cover 7 can effectively block aluminum ash, smoke, and high-temperature splashes generated during the operation of the aluminum melting furnace, preventing contaminants from adhering to the lens of the camera 11. This avoids poor heat dissipation or damage to optical components caused by long-term dust accumulation, thus extending the service life of the camera 11. When the monitoring device is working, the camera 11 can observe the internal working conditions of the aluminum melting furnace in real time, allowing staff to keep abreast of the melting status. When the first motor 4 on the upper surface of the bottom of the mounting shell 1 is started, the first motor 4 drives the reciprocating lead screw 10 to rotate, and drives another reciprocating lead screw 10 to rotate synchronously through the synchronous pulley 16 and the synchronous belt 17. Under the constraint of the limit rod 9, the moving block 8 moves up and down along the reciprocating lead screw 10, while simultaneously moving the cleaning frame 5. The brush bristles 6 on the inner wall of the cleaning frame 5 can periodically clean the outer surface of the protective cover 7 to ensure its light transmittance and prevent dust residue from affecting the clarity of the monitoring image, thereby maintaining the stable operation of the camera 11. This not only improves the reliability of the monitoring device but also reduces the frequency of manual maintenance. It is suitable for high-temperature and high-dust working environments in aluminum melting furnaces. The second motor 14, which is set on the lower surface of the top of the mounting shell 1, drives the second gear 15 connected to its output shaft to rotate. The second gear 15 meshes with the first gear 13 fixed on the rotating rod 12, driving the rotating rod 12 and the camera 11 installed at its bottom to rotate synchronously. This enables precise adjustment of the shooting angle of the camera 11, optimizes the adjustable range of the monitoring field of view, and allows the staff to flexibly adjust the observation angle according to the working conditions inside the aluminum melting furnace.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
