[0002] For opposed combustion boilers, the air intake and swirl intensity of a single burner are adjusted by the burner adjustment lever, which plays a vital role in coal powder combustion. At present, most burner adjustment levers are in the on-site manual adjustment mode. After the combustion adjustment test, the opening is fixed at a certain opening and no longer changes. During routine operation, the operating personnel cannot make remote adjustments according to the combustion parameters, and cannot adapt to the boiler load, coal mill combination mode, and coal type changes, resulting in deterioration of combustion under certain working conditions. In order to improve the adaptability of boiler combustion, it is necessary to remotely control the burner adjustment lever. At present, only a small number of opposed combustion boilers have remotely controlled burner levers, which are basically driven by pneumatic pistons. They can only adjust a fixed opening and are not responsive.

[0075] Further, the servo motor 103b is fixed to the lateral transmission shaft on the upper left side of the worm gearbox 103c;

[0084] Furthermore, the material of the fixing bracket 103a is Q102d5 angle iron;

[0085] The power output shaft center hole of the worm gearbox 103c is designed to be concentric with the transmission shaft 102a;

[0086] The opening sensor 103e is arranged at the front side of the worm gearbox 103c and is designed to be concentric with the power output shaft center hole.

[0087] It should be noted that the shutter door 101a and the door shaft 101b are of integrated design, the anti-stuck chain teeth 101c are installed and fixed on the door shaft 101b and are designed concentrically with the door shaft 101b, and the shutter door 101a and the anti-stuck chain teeth 101c are arranged in N equal parts of 360 degrees around the burner, and then the chain 101d is used to connect these anti-stuck chain teeth 101c to achieve a 360-degree arrangement. All anti-stuck chain teeth 101c can be adjusted and rotated synchronously with the chain 101d, and the transmission shaft 102a and the shaft head 102b are of integrated design, and the shaft The head 102b is connected to the anti-stuck chain tooth 101c, the fixed sleeve 102c is installed on the perforated pipe wall, and then the transmission shaft 102a is inserted through it, and the high-temperature resistant sealing ring 102d inside the fixed sleeve 102c is used to seal the gap between the transmission shaft 102a and the fixed sleeve 102c to prevent the high-pressure and high-temperature hot air in the pipeline from escaping, and then the pointer 102e fixed on the transmission shaft 102a will point to the corresponding scale of the dial 102f, and the tail end of the transmission shaft 102a passes through and is fixed on the shaft hole of the worm gearbox 103c.

[0088] When in use, the design of the shutter damper 101a changes the traditional adjustment method, and the use effect is improved with the support of the remote control component 103. The combination of the anti-stuck sprocket 101c and the chain 101d can effectively reduce the dust accumulation and jamming phenomenon and improve the smoothness of adjustment. The servo motor 103b controls the rotation range of the servo motor 103b with the cooperation of the opening sensor 103e. The rotation drives the worm gearbox 103c to rotate within a certain range. The worm gearbox 103c amplifies the torque and transmits it to the transmission shaft 102a. Due to the principle that the force of the worm gear set cannot be transmitted in reverse, when the servo motor 103b stops rotating, the worm gearbox 103c is immediately locked to ensure that the shutter damper 101a is no longer deflected and displaced. The transmission shaft 102a then transmits the torque to one of the anti-stuck sprockets 101c for synchronous operation. The anti-stuck sprocket 101c drives the chain 101d, and the chain 101d transmits the torque to all other anti-stuck sprockets 101c distributed in a 360-degree ring. These anti-stuck sprockets 101c drive the door shaft 101b and the shutter damper 101a to rotate simultaneously within a certain range. Due to the structural characteristics of the anti-stuck sprocket 101c and the chain 101d, dust accumulation will not get them stuck. When manual adjustment is required on site, the power source switching clutch 103d is operated to disconnect the power source of the servo motor 103d and connect the manual adjustment disk 103f to the worm gearbox 103c for manual adjustment mode. The opening of the adjustment can be intuitively seen on site with the pointer 102e and the dial 102f components. At the end of the adjustment, the power source switching clutch 103d is operated again to disconnect the power connection of the manual adjustment disk 103f and switch back to the power source control of the servo motor 103b.

[0089] When the servo motor 103b receives the command, it drives the worm gearbox 103c with the cooperation of the opening sensor 103e, and then the worm gearbox 103c amplifies the torque and transmits it to the transmission shaft 102a. At this time, the transmission shaft 102a transmits the torque to the anti-stuck sprocket 101c connected to it through the opening sensor 103e, and then transmits the torque to all the anti-stuck sprockets 101c through the chain 101d. All the anti-stuck sprockets 101c drive the door shaft 101b to rotate, and the door shaft 101b drives the shutter damper 101a to rotate. When the opening sensor 103e monitors the command opening, it feeds back the information to the central control, and the central control sends a command to the servo motor 103b to stop running. If there is a need for maintenance or on-site operation, the on-site power source switching clutch 103d is operated to disconnect the mechanical connection of the servo motor 103b, and switch to the manual adjustment disk 103f for on-site manual adjustment. During manual adjustment, refer to the indication between the pointer 102e and the dial 102f to indicate the opening status of the louver damper 101a. Of course, at this time, the opening sensor 103e can also feedback the opening information at this time to the central control. Similarly, in the remote control state, the opening status can also be intuitively seen from the external pointer 102e and dial 102f.

[0090] In summary, the design of the shutter damper is improved from the traditional complex transmission mode multi-link transmission mechanism to the anti-stuck sprocket and chain mode adjustment, which can effectively reduce the accumulation of dust and improve the smoothness of adjustment. First, the shutter damper is evenly distributed in the burner 360-degree annular damper N, and the door shaft is fixed on both sides of the annular damper, and then the anti-stuck sprocket is installed at one end of each door shaft, and finally all the anti-stuck sprockets are linked together by a chain to form a circle. Then, on one of the anti-stuck sprockets, it is connected to the shaft head at the same center of the transmission shaft, and the transmission shaft then passes through the pipe wall and is fixed on the fixed sleeve to avoid the outside. In order to prevent the high-temperature and high-pressure hot air in the pipeline from escaping, there is a circle of high-temperature resistant sealing ring in the fixed sleeve to ensure sealing without affecting the rotation of the transmission shaft. A fixed pointer is installed on the side wall of the transmission shaft near the fixed sleeve, and a dial is installed on the outer wall of the pipe above the fixed sleeve to indicate the opening of the shutter damper during manual adjustment. The end of the transmission shaft is inserted into the axial center hole of the power output of the worm gearbox and fixed. An opening sensor is installed on the side of the worm gearbox at the end of the transmission shaft to feed back the opening information to the central control. The bottom of the worm gearbox is fixed on the fixed bracket, the upper horizontal axis of the left side is installed with a fixed servo motor, and the upper horizontal axis of the right side is installed with a fixed manual adjustment disk. A power source switching clutch is provided on the upper left of the worm gearbox for switching the power connection between the servo motor and the manual adjustment disk.
