Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot rolling safety and environmental protection production technology, specifically a device for controlling compressed air consumption. Background Technology
[0002] In modern steel production processes, dust removal equipment for sintered steel plates plays a crucial role, providing an irreplaceable foundation for maintaining the working environment of the rolling mill, ensuring product quality, and extending equipment lifespan. Sintered steel plate dust removal technology, with its high dust removal efficiency and stable operating performance, has been widely applied in the steel industry. However, during the operation of the sintered steel plate dust removal system, the pneumatic solenoid valve, as a key component controlling dust removal and cleaning, directly impacts the dust removal effect and production costs.
[0003] Pneumatic solenoid valves use compressed air as a power source to clean and discharge dust in sintered steel plate dust removal systems. In a complete rolling mill line, up to three hundred pneumatic solenoid valves are typically configured to ensure effective dust removal. These valves consume a significant amount of compressed air during continuous operation, becoming a major component of the rolling mill's energy consumption. Especially during shutdowns, if the solenoid valves remain open, they not only continue to consume compressed air, wasting energy, but may also affect the overall energy consumption indicators of the rolling process, thereby increasing production costs and reducing the company's economic benefits. Currently, most companies still manually shut down the solenoid valves during shutdowns. This method is not only inefficient and increases the labor intensity of workers, but is also prone to delays or omissions due to human error, further exacerbating the energy waste problem. Therefore, we propose a device to control compressed air consumption to solve the above problems. Utility Model Content

[0023] Example
[0024] like Figure 1-4As shown, an embodiment of this utility model discloses a device for controlling compressed air consumption, including a compressed air storage tank 1. An outlet pipe 2 is connected to and fixed to one side of the compressed air storage tank 1. A manual valve 3 is provided at the end of the outlet pipe 2. A valve body 4 is threadedly connected to one side of the manual valve 3 via multiple bolts. A transmission rod 5 is rotatably connected to the valve body 4. The end of the transmission rod 5 extends into the valve body 4 and is provided with a valve plate 6. Two U-shaped brackets 7 are fixedly connected to the top of the valve body 4. A control box 8 with an opening on the front side is fixedly connected to the top of the two U-shaped brackets 7. The transmission rod 5... The top of the valve body 4 extends into the control box 8 and is fixedly connected to a first gear 9. A motor 10 is fixedly connected to the inner top wall of the control box 8. A second gear 11 is fixedly connected to the output shaft of the motor 10, and the second gear 11 meshes with the first gear 9. A processor 12, a signal receiver 13, and a signal connector 14 are fixedly connected to the inner rear wall of the control box 8. A connecting pipe 15 is threadedly connected to one side of the valve body 4 via multiple bolts. The pipe is connected to an external precision rolling operation control computer via the signal connector 14. The control computer will program the required amount of compressed air according to the amount of compressed air needed by the sintered plate dust removal equipment. The corresponding program sends control signals to the device. The signal receiver 13 is responsible for receiving these signals and transmitting them to the processor 12 for processing. The processor 12 calculates the required valve opening degree according to the preset program and algorithm. The processor 12 controls the start of the motor 10, which drives the second gear 11 to rotate. The second gear 11 drives the transmission rod 5 to rotate through the first gear 9. The transmission rod 5 drives the valve plate 6 to rotate, thereby adjusting the opening degree of the valve plate 6 and realizing automatic adjustment. In the peak avoidance organization mode, the operator can remotely send opening and closing commands to the control box 8 through the industrial control computer. The processor 12 controls the start or stop of the motor 10 according to the received commands. When the manual valve 3 at the outlet of the compressed air storage tank 1 is fully open, the valve opening degree can be adjusted according to the on-site production situation, and the electric regulating valve can be remotely opened and closed. This saves compressed air consumption, achieves energy saving and cost reduction, and further reduces energy consumption. It can adapt to the current peak avoidance organization production mode, realize the simultaneous operation of environmental protection equipment and production, and achieve particulate matter emission standards. It solves the problem of energy waste caused by the previous manual adjustment and valve opening and closing on-site.
[0025] In some embodiments, the processor 12, signal receiver 13, signal connector 14, and motor 10 are electrically connected via conductive lines.
[0026] In some embodiments, a cover 16 is rotatably connected to the front side of the control box 8, and a U-shaped block 17 is fixedly connected to the top of the cover 16.
[0027] In some embodiments, a rectangular block 18 is fixedly connected to the top of the control box 8, and a fixing rod 19 is fixedly connected to one side of the rectangular block 18. The fixing rod 19 serves to fix the block.
[0028] In some embodiments, a movable rod 20 is slidably connected to the fixed rod 19, and an L-shaped locking block 22 is fixedly connected to the end of the movable rod 20. The L-shaped locking block 22 is engaged with the U-shaped block 17, and the U-shaped block 17 serves to fix the rod.
[0029] In some embodiments, a spring 21 is welded between the other end of the movable rod 20 and one side of the rectangular block 18. The spring 21 is movably sleeved on the fixed rod 19. The movable rod 20 serves as a connection.
[0030] Working principle or structural principle: During use, compressed air is compressed by a specific device and stored in compressed air storage tank 1, providing a stable compressed air source for production. It connects to an external precision rolling mill control computer via signal connector 14. Based on the amount of compressed air required by the sintered plate dust removal equipment, the control computer programs a corresponding program and sends control signals to the device. Signal receiver 13 receives these signals and transmits them to processor 12 for processing. Processor 12 calculates the required valve opening based on a preset program and algorithm. Processor 12 controls the start of motor 10, which drives the second gear 11 to rotate. The second gear 11 drives the transmission rod 5 to rotate via the first gear 9. The transmission rod 5 drives the valve plate 6 to rotate, thereby adjusting the valve plate 6 opening and achieving automatic adjustment. In peak shaving mode, operators can control the operation via the control computer. The machine remotely sends opening and closing commands to the control box 8. The processor 12 controls the start or stop of the motor 10 according to the received commands. When the manual valve 3 at the outlet of the compressed air storage tank 1 is fully open, the valve opening can be adjusted according to the on-site production situation. At the same time, the electric regulating valve can be remotely opened and closed, saving compressed air consumption, achieving energy saving and cost reduction, further reducing energy consumption, adapting to the current peak avoidance production mode, realizing the simultaneous operation of environmental protection equipment and production, and achieving particulate matter emission standards. It solves the problem of wasted energy caused by the previous need to manually adjust and open and close valves on-site. When it is necessary to open the box cover 16, pull the L-shaped locking block 22. The L-shaped locking block 22 drives the moving rod 20 to slide on the fixed rod 19 and stretches with the spring 21, so that the L-shaped locking block 22 separates from the U-shaped block 17. Then, rotate the box cover 16 to open it, so that the inside of the control box 8 can be maintained.
