Technical Field

[0002] The modular controller for waste heat recovery boilers is an intelligent control device developed to achieve efficient and stable operation of waste heat recovery boilers and improve energy recovery efficiency. It aims to precisely manage the operating parameters of each stage of the waste heat recovery boiler through modular design and intelligent control functions, meeting the energy recycling needs of industrial production. This modular controller is widely used in metallurgy, chemical industry, building materials and other industries.

[0003] The modular controller for waste heat recovery boilers integrates precise control, modular design, and fault early warning technology to provide a reliable control solution for industrial waste heat recovery.

[0012] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a modular controller for a waste heat recovery boiler, including a housing 1, which can effectively protect the internal components. The circuit board 14 is responsible for receiving and processing signals and controlling the boiler operating parameters. A motor 2 is connected to the inner wall fixing rod of the housing 1, and a rotating arm 3 is fixedly connected to the drive end of the motor 2. Motor 12 provides power for the movement of the movable plate 13. By precisely controlling the speed, direction and start / stop of motor 12, the precise movement of the rotating arm 3 can be achieved. Support plate 14 is fixedly connected to the inner wall of the outer shell 1. Swing frame 5 is rotatably connected to the rear side of support plate 14. Support plate 14 enhances the stability of swing frame 5 installation. Sliding block 6 is slidably connected to the inner wall of swing frame 5. Sliding block 6 slides in swing frame 5, thereby driving swing frame 5 to swing. Sliding seat 7 is rotatably connected to the top of swing frame 5. The outer wall of the sliding seat 7 is fixedly connected to the second support plate 8. The swinging motion of the swing frame 5 can drive the sliding seat 7 and the second support plate 8 to move horizontally back and forth together. The inner wall of the second support plate 8 is fixedly connected to the sliding column 9. The inner wall of the outer shell 1 is fixedly connected to two limit blocks 10. The second support plate 8 drives the sliding column 9 to slide on the inner wall of the limit block 10. The outer wall of the sliding column 9 is fitted with two springs 11, which play a role in buffering and resetting. The inner wall of the outer shell 1 is provided with a limit component to prevent the circuit device from shaking.
[0013] Reference Figure 3 The limiting component includes a circuit board 14. The outer wall of the circuit board 14 is detachably connected to the inner wall of the outer shell 1. The detachable connection between the circuit board 14 and the outer shell 1 supports quick replacement or upgrade, meeting the maintenance needs of the waste heat recovery boiler control system. The outer wall of the circuit board 14 has a groove 15, which provides a snap-fit position for the limiting plate 19. The inner wall of the outer shell 1 is fixedly connected to a motor 16, and the drive end of the motor 16 is fixedly connected to a gear 17. Motor 16 drives gear 17 to rotate. A limiting post 18 is fixedly connected to the inner wall of the outer shell 1. A limiting plate 19 is slidably connected to the outer wall of the limiting post 18. The limiting plate 19 is driven to slide along the limiting post 18 by rack 20, so that the limiting plate 19 is embedded in the groove 15 of the circuit board 14, realizing the automatic clamping and fixing of the circuit board 14. A rack 20 is fixedly connected to the rear side of the limiting plate 19, and the rack 20 drives the limiting plate 19 to move together.
[0014] Reference Figures 2 to 4 The inner wall of the swing frame 5 is provided with a groove 12. The outer wall of the sliding block 6 is slidably connected to the inner wall of the groove 12. The top end of the rotating arm 3 is in contact with the inner wall of the sliding block 6. When the rotating arm 3 rotates, its top end pushes the sliding block 6 to slide back and forth in the groove 12, converting the circular motion of the rotating arm 3 into the linear motion of the sliding block 6, thereby driving the swing frame 5 to swing around the support plate 4. Two springs 11 are fixedly connected to the outer wall of the support plate 2 8 on their adjacent sides. The springs 11 provide deceleration and buffer for the movement of the support plate 2 8. Two springs 11 are fixedly connected to the outer wall of the limiting block 10 on their far sides. The limiting block 10 provides support for the springs 11. The outer wall of the sliding column 9 is slidably connected to the inner wall of the two limiting blocks 10. The limiting blocks 10 provide motion guidance for the sliding column 9. A moving plate 13 is fixedly connected to the outer wall of the support plate 2 8. The top of the moving plate 13 is slidably connected to the inner wall of the outer shell 1. The movement of the moving plate 13 driven by the support plate 2 8 can reduce dust entering the controller. The gear 17 is meshed with the rack 20. The outer wall of the limiting plate 19 is detachably connected to the outer wall of the circuit board 14.

The outer wall of the limiting block 10 is fixedly connected to the inner wall of the groove 22. The groove 22 optimizes the spatial layout, making the support plate 4 and the limiting block 10 more compactly installed.
[0015] Working principle: When motor 2 drives rotating arm 3 to rotate clockwise, during the process of sliding block 6 moving from a position away from sensor 21 to a position close to sensor 21, rotating arm 3 rotates clockwise, and sliding block 6 slides from the middle position of the inner wall of slide groove 12 to the top position of the inner wall, and sliding block 6 slides from the top position of the inner wall of slide groove 12 to the middle position of the inner wall. At the same time, the sliding block 6 causes the swing frame 5 to tilt towards the sensor 21, and the swing frame 5 causes the sliding seat 7 and the second support plate 8 to move towards the sensor 21. The second support plate 8 slides to the left along the inner wall of the limit block 10. One of the springs 11 in the direction of the sensor 21 is compressed, and the other spring 11 in the direction away from the sensor 21 is stretched. At this time, the outer shell 1 completes the heat dissipation operation. As motor 2 continues to drive rotating arm 3 to rotate clockwise, during the process of sliding block 6 moving from a position close to sensor 21 to a position far away from sensor 21, rotating arm 3 rotates clockwise, and sliding block 6 slides from the middle position of the inner wall of slide groove 12 to the bottom position of the inner wall, and sliding block 6 slides from the bottom position of the inner wall of slide groove 12 to the middle position of the inner wall. At the same time, the sliding block 6 causes the swing frame 5 to tilt away from the sensor 21, and the swing frame 5 causes the sliding seat 7 and the second support plate 8 to move away from the sensor 21. The second support plate 8 slides to the right along the inner wall of the limit block 10. One of the springs 11 away from the sensor 21 is compressed, and the other spring 11 close to the sensor 21 is stretched. At this time, the outer shell 1 completes the sealing operation. Motor 2 16 drives gear 17 to rotate counterclockwise. Gear 17 drives rack 20 to move backward. Gear 17 drives limit plate 19 to move backward along the outer wall of limit post 18. The outer wall of limit plate 19 contacts the inner wall of groove 15. At this time, the installation operation of circuit board 14 is completed. Motor 2 16 drives gear 17 to rotate clockwise. Gear 17 drives rack 20 to move forward. Gear 17 drives limit plate 19 to move forward along the outer wall of limit post 18. The outer wall of limit plate 19 separates from the inner wall of groove 15. At this time, the disassembly operation of circuit board 14 is completed.
