Description

Technical Field

[0001] The present invention relates to the technical field of silicon steel sheets, and more specifically, to a heat exchange system for a silicon steel sheet production line. Background Art

[0002] As an important magnetic material, silicon steel sheets are widely used in industries such as electricity, electronics and motor manufacturing. However, during the production process, especially on continuous production lines, silicon steel sheets need to undergo multiple heat treatment steps, including annealing, cooling, etc., to adjust their microstructure and magnetic properties. During these processes, the efficiency and stability of the heat exchange system are directly related to the production quality and efficiency of silicon steel sheets.

[0003] According to the patent document: CN110373518A, a quick cooling furnace box waste heat recovery device for a heat treatment furnace for cold-rolled silicon steel sheets of a motor is disclosed, which includes a furnace box body and a heat collecting hood arranged front and back, the front port of the furnace box body is fixedly provided with a connecting end plate and the rear port thereof is connected to the heat collecting hood, a serpentine heat exchange coil is arranged in the heat collecting hood, and a rectangular heat exchange coil is arranged in the furnace box body, the two tubes are connected, and the two tubes respectively have an infusion pipe port and a liquid outlet pipe port for the liquid heat exchange medium to pass in and out, the infusion pipe port and the liquid outlet pipe port are located outside the heat collecting hood and outside the furnace box body, and the liquid outlet pipe port is externally connected to a heat storage container. By adopting the above scheme, the liquid heat exchange medium flows through the serpentine heat exchange coil through the infusion pipe port and exchanges heat with the heat in the heat collecting cover. When the liquid heat exchange medium flows through the rectangular heat exchange coil, it exchanges heat with the high-temperature waste heat in the furnace box, greatly reducing the high-temperature waste heat surging from the furnace box to the heat collecting cover, and weakening the high-temperature waste heat discharged from the exhaust port on the top of the heat collecting cover to the external environment. As the heat exchange continues, the high-temperature waste heat is effectively recovered.

[0004] Silicon steel sheets need to be heat treated during the production process, and the temperature and pressure control in the furnace box is the key to achieving high-quality silicon steel sheet production. When the furnace box needs to release the internal pressure, it is usually achieved by condensing and discharging the internal hot air. However, the heat exchange system often has problems such as low heat recovery efficiency and high energy consumption. A large amount of heat flows through the high-temperature exhaust gas fume hood exhaust section and is discharged from the exhaust port on its top. In the existing silicon steel sheet production line, the emission of high-temperature exhaust gas not only leads to energy waste, but also may cause thermal pollution to the environment.

The rear side of the baffle plate 4214 is movably connected to the front end of the air delivery bin air inlet pipe 423 extending to the inner wall of the air delivery bin body 421.

[0037] When heat treating the silicon steel sheet, the silicon steel sheet is heated by the high temperature environment of the furnace box 3 to reach the required process temperature. In this process, the hot air generated in the furnace box is effectively sucked into the exhaust box 41 through the furnace box exhaust pipe 4110. After the exhaust fan motor 413 is started, the drive turntable 414 rotates, thereby driving the crawler belt 415 and the second turntable 416 to rotate. This linkage mechanism causes the exhaust fan rotating pipe 418 and the exhaust fan 4111 to rotate accordingly, forming a strong suction force, which quickly sucks the hot air in the furnace box and transports it to the air delivery bin 42 through the air delivery pipe 419;

[0038] The air delivery bin body 421 serves as a transfer station for hot air. The hot air inside it receives the hot air from the air extraction box 41 through the air delivery bin air inlet pipe 423, and is prepared to be further distributed to the heat exchange system or the gas detection mechanism 5. When the hot air enters the air delivery bin, the gear rotating rod 424 drives the third turntable 417 to rotate while the exhaust fan motor 413 drives the exhaust fan rotating pipe 418 to rotate. The third turntable 417 drives the fourth turntable 425 to rotate through the second crawler 426, thereby realizing the synchronous coordination of the air extraction and air delivery processes. The meshing action of the gear 427 and the second gear 428 drives the connecting rod 429 and the semicircular turntable 4210 to rotate. The special meshing relationship between the semicircular gear 4211 and the irregular-shaped gear 4212, when the semicircular turntable 4210 and the semicircular gear 4 After 211 rotates one circle, the semicircular gear 4211 engages with the irregular gear 4212 to drive the baffle connecting rod 4215 to rotate, so that the baffle connecting rod 4215 and the baffle 4214 can periodically open and close the entrance of the air supply bin air inlet pipe 423, thereby realizing precise control of the hot gas flowing into the air supply bin body 421. This design not only ensures a stable supply of hot gas, but also avoids the adverse effects on subsequent processing processes caused by excessive or insufficient hot gas flow. When the baffle 4214 is in the open state, the hot gas smoothly enters the air supply through the air supply bin air inlet pipe 423, and the flow and speed of the hot gas entering the heat exchange box 25 are precisely controlled. This intelligent adjustment mechanism not only improves the efficiency of the heat exchange system, but also ensures the stability and reliability of the heat treatment process of the silicon steel sheet.

[0039] like Figure 8-10 As shown, the bottom plate 1 includes a bottom plate body 11, and the front and rear sides of the top of the bottom plate body 11 are fixedly connected with transmission rods 12 respectively, and the two transmission rods 12 each include a bottom rod 121, and the tops of the two bottom rods 121 are fixedly connected with top rods 123, and the tops of the two bottom rods 121 are provided with sliding grooves 122 on the side away from the top rod 123, and the opposite surfaces of the two top rods 123 are provided with top rod sliding grooves 124, and the tops of the two top rods 123 are fixedly connected with racks 125, and the gas detection mechanism 5 includes a gas detection mechanism connecting plate 51, and the bottom of the gas detection mechanism connecting plate 51 is fixedly connected with a slider 52, and the outer wall of one side of the slider 52 is slidably connected to the inner wall of the top rod sliding groove 124, and the side of the gas detection mechanism connecting plate 51 away from the top rod sliding groove 124 is fixedly connected with a motor placement block 55, and the top of the gas detection mechanism connecting plate 51 is fixedly connected with a gear turntable connecting block 53, and the top of the motor placement block 55 The motor 56 is fixedly connected to the gear turntable connecting block 53, and the output end of the motor 56 extends to one side of the gear turntable connecting block 53 and is fixedly connected to the gear turntable connecting plate 57. The outer wall of the gear turntable connecting plate 57 is fixedly connected to the gear turntable 54. The outer wall of the gear turntable 54 is meshed with the rack 125 fixed to the top of the top rod 123. A ball shaft connecting groove 58 is opened on one side of the gear turntable connecting plate 57. The inner wall of the ball shaft connecting groove 58 is rotatably connected to the ball shaft 59. The side of the ball shaft 59 away from the ball shaft 59 is fixedly connected to a U-shaped connecting frame 510. The inner side of the U-shaped connecting frame 510 is rotatably connected to a detector connecting block 511. The top of the detector connecting block 511 is fixedly connected to a detector 512. The bottom of the detector connecting block 511 is rotatably connected to a bottom supporting plate 513. The bottom of the bottom supporting plate 513 is fixedly connected to a bottom supporting plate slider 514. The outer wall of the bottom supporting plate slider 514 is slidably connected to the inner wall of the slide groove 122.

[0040] When it is necessary to detect whether there is gas leakage around the furnace box 3, the motor 56 is started, and the motor immediately drives the gear turntable connecting plate 57 and the gear turntable 54 thereon to start rotating, and the gear turntable 54 is tightly meshed with the rack 125 fixed on the top of the top rod 123. This design ensures that the gear turntable can move smoothly left and right along the top rod, thereby driving the entire gas detection mechanism 5 to move horizontally along the trajectory of the transmission rod 12;

[0041] As the gas detection mechanism 5 slowly moves, the detector 512 is accurately guided to the key detection points around the furnace box 3. The detector 512 is internally integrated with a highly sensitive gas sensor, which can quickly capture any tiny signs of gas leakage, whether it is harmful gases that may escape during the heat treatment process or environmental gas infiltration caused by poor sealing of the furnace body, which can be effectively identified and recorded;

[0042] At the same time, the flexible connection design between the U-shaped connecting frame 510 and the detector connecting block 511 enables the detector 512 to maintain horizontal movement while also having a certain left and right fine adjustment capability. When the gear turntable 54 rotates, it drives the ball shaft 59 to rotate in the ball shaft connecting groove 58. This unique rotation and sliding combination mechanism gives the detector 512 an additional degree of freedom. The ball shaft 59, as a connection point, not only allows the detector 512 to move horizontally along the trajectory of the transmission rod 12, but also allows the detector 512 to swing left and right through its rotation characteristics, so as to detect the detection area more accurately.

[0043] When the gas detection mechanism 5 completes the comprehensive detection of the entire area around the furnace box 3, the motor 56 stops working, and the data collected by the detector 512 will be transmitted to the control system for analysis and processing. According to the analysis results, the control system will automatically determine whether there is a gas leakage problem in the furnace box, and take corresponding measures to repair or adjust it to ensure the safety and stability of the heat treatment process of the silicon steel sheet.

[0044] Working principle of the present invention: when heat treating silicon steel sheets, the silicon steel sheets are heated by the high temperature environment of the furnace box 3 to reach the required process temperature. In this process, the hot air generated in the furnace box is effectively sucked into the exhaust box 41 through the furnace box exhaust pipe 4110. After the exhaust fan motor 413 is started, the turntable 414 is driven to rotate, thereby driving the crawler 415 and the second turntable 416 to rotate. This linkage mechanism causes the exhaust fan rotating pipe 418 and the exhaust fan 4111 to rotate accordingly, forming a strong suction force, which quickly sucks the hot air in the furnace box and transports it to the air delivery bin 42 through the air delivery pipe 419. The air delivery bin main body 421 serves as a transfer station for hot air. The hot air inside it receives the hot air from the exhaust box 41 through the air delivery bin air inlet pipe 423, and is prepared to be further distributed to the heat exchange system or the gas detection mechanism 5. When the hot air enters the air delivery bin, the gear rotating rod 424 drives the exhaust fan rotating pipe 418 to rotate when the exhaust fan motor 413 drives the exhaust fan motor 413 to rotate. At the same time, the third turntable 417 is driven to rotate, and the third turntable 417 drives the fourth turntable 425 to rotate through the second crawler 426, thereby realizing the synchronous coordination of the air extraction and air delivery processes. The meshing action of the gear 427 and the second gear 428 drives the connecting rod 429 and the semicircular turntable 4210 to rotate. The special meshing relationship between the semicircular gear 4211 and the irregular gear 4212, when the semicircular turntable 4210 and the semicircular gear 4211 rotate one circle, the semicircular gear 4211 meshes with the irregular gear 4212 to drive the baffle connecting rod 4215 to rotate, so that the baffle connecting rod 4215 and the baffle 4214 can periodically open and close the entrance of the air supply bin air inlet pipe 423, thereby realizing the precise control of the hot gas flowing into the air supply bin main body 421. This design not only ensures the stable supply of hot gas, but also avoids the adverse effects on the subsequent processing process caused by excessive or insufficient hot gas flow. When the baffle 4214 is in the open state, the hot air smoothly enters the air supply through the air supply bin air inlet pipe 423, and the flow rate and speed of the hot air entering the heat exchange box 25 are accurately controlled. This intelligent adjustment mechanism not only improves the efficiency of the heat exchange system, but also ensures the stability and reliability of the heat treatment process of the silicon steel sheet;

[0045] When it is necessary to detect whether there is a gas leak around the furnace box 3, the motor 56 is started, and the motor immediately drives the gear turntable connecting plate 57 and the gear turntable 54 thereon to start rotating. The gear turntable 54 is tightly meshed with the rack 125 fixed on the top of the top rod 123. This design ensures that the gear turntable can move smoothly left and right along the top rod, thereby driving the entire gas detection mechanism 5 to move horizontally along the trajectory of the transmission rod 12. As the gas detection mechanism 5 moves slowly, the detector 512 is accurately guided to the key detection points around the furnace box 3. The detector 512 is integrated with a highly sensitive gas sensor, which can quickly capture any tiny signs of gas leakage, whether it is harmful gases that may escape during the heat treatment process or environmental gas infiltration caused by poor furnace sealing. It can be effectively identified and recorded. At the same time, the flexible connection between the U-shaped connecting frame 510 and the detector connecting block 511 The design enables the detector 512 to maintain horizontal movement while also having a certain left and right fine-tuning ability. When the gear turntable 54 rotates, it drives the ball shaft 59 to rotate in the ball shaft connecting groove 58. This unique combination of rotation and sliding mechanism gives the detector 512 additional degrees of freedom. The ball shaft 59 serves as a connection point, which not only allows the detector 512 to move horizontally along the trajectory of the conveying rod 12, but also allows the detector 512 to swing left and right through its rotation characteristics, so as to more accurately detect the detection area. When the gas detection mechanism 5 completes the comprehensive detection of the entire area around the furnace box 3, the motor 56 stops working, and the data collected by the detector 512 will be transmitted to the control system for analysis and processing. According to the analysis results, the control system will automatically determine whether there is a gas leakage problem in the furnace box, and take corresponding measures to repair or adjust it, so as to ensure the safety and stability of the heat treatment process of the silicon steel sheet.
