[0002] Pneumatic double-walled valves are commonly used auxiliary equipment in modern industrial bulk material conveying. Due to their excellent performance and reliability, they have been widely used. This equipment has stable working performance and strong adaptability, and can maintain excellent operating conditions in various industrial environments. At the same time, pneumatic double-walled valves are easy to maintain, operate and maintain, reducing equipment downtime and maintenance time costs. In addition, pneumatic double-walled valves have good unblocking properties during the unloading process, which can ensure the smooth conveying of bulk materials and avoid blockage problems during the conveying process.

[0003] Traditional mechanical transmission methods have gradually revealed some obvious shortcomings over the years. First, the mechanical transmission system has a relatively complex structure involving many moving parts, making the design and installation of the overall system quite complicated. Second, due to long-term high-load operation, these mechanical parts are prone to wear and loosening, resulting in a high equipment failure rate and increasing the risk of production interruption. Furthermore, the complex structure and frequent failures lead to high maintenance costs. Enterprises not only need to invest a lot of time and resources in routine inspections and maintenance, but also need to regularly replace vulnerable parts, thereby increasing the overall operating costs. Summary of the Invention

[0019] As attached Figure 1 To be continued Figure 4 As shown: This embodiment provides a pneumatic double-layer valve programmable controller, including a base plate 1. Two fixing blocks 2 are fixedly connected to both sides of the surface of the base plate 1. A fixing rod 3 is fixedly connected to one side of the two fixing blocks 2. A first spring 4 is sleeved on the surface of the middle end of the fixing rod 3. Sliding frames 5 are fixedly connected to both ends of the first spring 4. The sliding frames 5 are slidably connected to the surface of the fixing rod 3. Rotating plates 6 are rotatably connected to the top of the two sliding frames 5. Fixing frames 7 are rotatably connected to the other end of the two rotating plates 6. A protective shell 8 is fixedly connected to the top of the fixing frame 7. Several grooves 9 are opened on the inner wall of the protective shell 8. A sliding rod 10 is slidably connected to the inner cavity of the groove 9. A second spring 11 is sleeved on the surface of the sliding rod 10. One end of the second spring 11 is fixedly connected to the surface of the sliding rod 10. The other end of the second spring 11 is in contact with the groove 9. One end of the sliding rod 10 extends to the outside of the groove 9 and is fixedly connected to a snap-fit ​​block 12.

[0020] Specifically, a controller 13 is provided on the surface of the inner cavity of the protective shell 8, and one side of the snap-fit ​​block 12 snaps onto the surface of the controller 13.

[0021] In this embodiment: The controller 13 is equipped with two miniature relays as output devices to precisely control the opening and closing of the upper and lower gate cylinders of the double-layer valve. Specifically, the controller 13 panel can set the opening and closing times of the upper and lower gates. The relays control the on / off state of the cylinder solenoid valves by periodically switching power on and off according to the set times, thereby achieving precise control of the gates. During operation, when the upper gate is open, the lower gate automatically closes; conversely, when the lower gate is open, the upper gate closes. This reciprocating motion of the upper and lower gates ensures smooth material feeding and effectively locks in the high-temperature flue gas in the boiler, preventing gas leakage or waste, ensuring the safety and stability of the system. Simultaneously, it improves the automation and accuracy of operation and reduces the need for manual intervention.

[0022] Specifically, grooves 14 are provided on both sides of the surface of the base plate 1, and one end of the sliding frame 5 is slidably connected to the inner cavity of the groove 14.

[0023] In this embodiment, the sliding groove 14 effectively ensures the smoothness and safety of the sliding frame 5 during movement, avoids affecting the performance due to uneven sliding or jamming, enhances stability, and extends service life.

[0024] Specifically, threaded holes 15 are provided at all four corners of the base plate 1, and bolts 16 are threaded into the inner cavity of the threaded holes 15.

[0025] In this embodiment, the main function of the threaded hole 15 and the bolt 16 is to securely fix the device in the designated position using the bolt 16, providing strong stability and reliability so that it will not shift or loosen during use. At the same time, it simplifies the installation process, improves installation efficiency, facilitates maintenance and disassembly, and provides users with a more convenient user experience.

[0026] Specifically, dampers 17 are fixedly connected to both sides of the surface of the base plate 1, and the two dampers 17 are symmetrically arranged at equal intervals.

[0027] In this embodiment, the damper 17 effectively absorbs and reduces the impact and vibration generated during movement, thus stabilizing the movement, reducing the vibration amplitude, thereby reducing the impact on other components and extending the service life of the device.

[0028] The working principle and usage process of this utility model: After the user fixes the device in the designated position using bolts 16, the user begins to install the controller 13. During the installation process, pressing the controller 13 causes the locking block 12 to be squeezed, which in turn drives the sliding rod 10 to slide in the groove 9. When the controller 13 is installed into the inner cavity of the protective shell 8, the second spring 11 will drive the locking block 12 back to the surface of the controller 13, thus completing the fixing process. As the controller 13 is started, the mechanical system begins to operate and generates vibration force, which will cause the controller 13 to vibrate. Long-term vibration will shorten the service life of the controller. In order to reduce the impact of this vibration on the service life of the controller 13, the protective shell 8 vibrates synchronously with the controller 13, thereby squeezing the fixed frame 7 fixedly connected to the bottom of the protective shell 8. The fixed frame 7 is rotatably connected to the rotating plate 6, and the rotating plate 6 is rotatably connected to the sliding frame 5, which drives the sliding frame 5 to slide on the surface of the fixed rod 3, thereby squeezing the first spring 4. When the first spring 4 recovers its elasticity, it generates a force opposite to that of the sliding frame 5, thereby achieving a vibration reduction effect. In addition, the bottom of the protective shell 8 Two dampers 17 are installed in the unit to further enhance the vibration reduction function, protect the internal components of the controller 13 from vibration, and extend their service life. When the controller 13 needs to start the pneumatic double-layer valve, the two internal miniature relays control the opening and closing of the upper and lower gate cylinders respectively. The user can set the opening and closing time of the upper and lower gates through the controller 13 panel. The relays control the opening and closing of the cylinder solenoid valves by timed power-on and power-off, thereby controlling the opening and closing of the gates. In specific operation, when the upper gate is open, the lower gate is closed, and when the lower gate is open, the upper gate is closed. The two gates work alternately to realize material feeding and lock the high-temperature flue gas of the boiler. Through the analysis of the actual working conditions of the double-layer valve, the user can program the action time of the relays as needed to accurately set the opening and closing time of the gates. Once the set time is reached, the relay will act, powering on to start the cylinder or powering off to close the cylinder, ensuring the efficient and accurate operation of the equipment. This intelligent control method improves the automation level of the equipment, ensures the accuracy and stability during operation, and reduces human error.
