[0003] As a highly automated mechatronic combustion device, the burner can be categorized by its functions into: air supply system, ignition system, detection system, fuel system, and electrical control system. The central pipeline, as a crucial component of the fuel system, plays a vital role in achieving combustion requirements through its structure adjustment. Furthermore, realizing intelligent adjustment of the burner presents a significant challenge. Therefore, the purpose of this invention is to provide a solution for achieving intelligent adjustment of the burner's central pipeline. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an adaptive central pipe extension and retraction adjustment device for burners. The device is driven to reciprocate by a servo actuator, thereby causing the central pipe extension and retraction section to extend and retract, so as to achieve intelligent extension and retraction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a burner adaptive center pipe telescopic adjustment device, comprising a center pipe adjustment mechanism, a mixing section main pipe, an adjustment shaft seat, a pressure rod, a mixing section fan connecting flange, a mixing section furnace mouth flange, and a fire-gathering pipe. The mixing section fan connecting flange is used to connect to the burner centrifugal fan, and the mixing section furnace mouth flange is used to connect to the furnace mouth of the combustion furnace. A fixed seat slides at the bottom end of the pressure rod, and the fixed seat is welded to the top of the mixing section main pipe for installing the pressure rod to press the center pipe adjustment mechanism. An adjustment structure is provided inside the center pipe adjustment mechanism. The adjustment shaft seat is used to weld to both sides of the mixing section main pipe for installing the center pipe adjustment mechanism. A sealing gasket is directly installed between the center pipe adjustment mechanism and the mixing section main pipe to ensure sealing at the gas inlet connection. The sealing gasket is made of 3mm thick EPDM rubber.

[0006] Furthermore, the central tube adjustment mechanism comprises an adjustment device, a central tube telescopic section, a central piston tube, a first central tube support column, and a slide rod assembly.

[0007] Furthermore, studs are welded to both sides of the telescopic section of the central tube and connected to the adjusting device, which performs reciprocating motion under the action of the adjusting device. A piston ring is installed at the central piston tube for sealing. A slide rod assembly is welded at an appropriate position on the telescopic section of the central tube to support the central tube and reduce friction when the adjusting device moves.

[0008] Furthermore, the slide rod assembly is welded to the telescopic section of the central tube in a 60° symmetrical direction. It is composed of a second central tube support column, an anti-slip nut, a slide rod fixing block, and a deep groove ball bearing. The second central tube support column has a threaded through hole and is welded to the telescopic section of the central tube. The head of the slide rod fixing block is welded with a screw to cooperate with the threaded hole of the second central tube support column. At the same time, the anti-slip nut is installed for limiting the position, which facilitates the adjustment of the direction and length of the slide rod assembly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 and Figure 2This utility model provides an embodiment of an adaptive center pipe telescopic adjustment device for a burner, comprising a center pipe adjustment mechanism 1, a mixing section main pipe 2, an adjustment shaft seat 6, a pressure rod 7, a mixing section fan connecting flange 5, a mixing section furnace mouth flange 4, and a fire-gathering pipe 3. The mixing section fan connecting flange 5 is used to connect to the burner centrifugal fan, and the mixing section furnace mouth flange 4 is used to connect to the furnace mouth. A fixed seat slides at the bottom of the pressure rod 7, and the fixed seat is welded to the top of the mixing section main pipe 2 for mounting the pressure rod 7 to press the center pipe adjustment mechanism 1. The center pipe adjustment mechanism 1 has an adjustment structure inside. The adjustment shaft seat 6 is welded to both sides of the mixing section main pipe 2 for mounting the center pipe adjustment mechanism 1. The center pipe adjustment mechanism 1 and the mixing section main pipe 2 are connected by an adjustment mechanism. A sealing gasket 8 is directly installed to ensure a seal at the gas inlet connection. The sealing gasket 8 is made of 3mm thick EPDM rubber. The central tube adjustment mechanism 1 includes an adjustment device 16, a central tube telescopic section 13, a central piston tube 12, a first central tube support column 11, and a slide rod assembly 15. The two sides of the central tube telescopic section 13 are welded with studs and connected to the adjustment device 16, and reciprocate under the action of the adjustment device 16. A piston ring 14 is installed at the central piston tube 12 for sealing. The slide rod assembly 15 is welded at an appropriate position on the central tube telescopic section 13 to support the central tube and reduce friction when the adjustment device 16 moves. The slide rod assembly 15 is welded to the central tube telescopic section 13 symmetrically at 60° to the left and right. It is respectively composed of a second central tube support column 151, a first central tube support column 11, and a slide rod assembly 15. The assembly consists of a sliding nut 152, a sliding rod fixing block 153, and a deep groove ball bearing 154. The second central tube support column 151 has a threaded through hole and is welded to the central tube extension section 13. A screw is welded to the head of the sliding rod fixing block 153 to mate with the threaded hole of the second central tube support column 151. An anti-slip nut 152 is also installed for limiting the position, facilitating adjustment of the direction and length of the sliding rod assembly 15. The deep groove ball bearing 154 is connected to the sliding rod fixing block 153 with bolts. The adjustment device 16 includes a servo motor 161, a support base 163, an adjustment shaft 168, an adjustment crank 167, a bushing 164, a bushing baffle 165, and a connecting rod 169. The servo motor 161 is connected to the support base 163 by screws and simultaneously fixed to the adjustment shaft seat 6 by M4 screws. Bushings 164 and bushing baffles 165 are added to both ends of the bearing seat 6 to reduce friction and improve structural stability. The adjusting crank 167 is fixed to both sides of the adjusting shaft 168 by screws and connected to the connecting rod 169. The main power of the device comes from the servo motor 161. The servo motor 161 is connected to the adjusting shaft 168 through the adapter shaft 162. The power of the servo motor 161 drives the adjusting shaft 168 to perform a 90° reciprocating rotation, thereby driving the adjusting crank 167 to follow the movement. Under the action of the adjusting crank 167, the connecting rod 169 drives the central tube extension section 13 to slide in the machine, thereby intelligently adjusting the extension length of the burner central tube. At the same time, under the action of the slide rod assembly 15, the resistance during sliding is reduced, and the central tube is adjusted for centering.

[0021] Specifically, the operator precisely installs the central pipe adjustment mechanism 1 within the internal space of the mixing section main pipe 2 to ensure the normal operation of the entire adjustment device 16. To prevent gas leakage, a sealing gasket 8 is installed at the gas inlet junction of the central pipe adjustment mechanism 1 and the mixing section main pipe 2 to further enhance leak prevention. The central pipe telescopic section 13 is then connected to the adjustment device 16 via studs on both sides, allowing it to reciprocate precisely under the action of the adjustment device 16. To ensure the sealing of the central piston pipe 12 during movement, a piston ring 14 is installed at its position to completely prevent gas leakage. After ensuring a proper seal at the junction of the central piston pipe 12 and the gas inlet, the operator fixes the sliding rod assembly 15 to the appropriate position on the central pipe telescopic section 13, ensuring that the sliding rod assembly 15 is symmetrically welded to the central pipe telescopic section 13 at 60° angles to reduce friction and wear during adjustment. The operator then starts the servo motor 161, which drives the adjusting shaft 168 to reciprocate 90° via the adapter shaft 162. The rotation of the shaft 168 causes the adjusting crank 167 to switch to linear motion. The rotation of the adjusting crank 167 then drives the connecting rod 169 to move the central tube telescopic section 13, allowing it to slide within the mixing section main pipe 2. During the adjustment process, the deep groove ball bearing 154 in the slide rod assembly 15 is connected to the slide rod fixing block 153 by bolts, greatly reducing the friction of the central tube telescopic section 13 during movement and ensuring the smoothness and accuracy of the adjustment process. At the same time, the piston ring 14 at the central piston tube 12 continues to function, ensuring that no gas leakage occurs during the adjustment process. When the central tube telescopic section 13 reaches the required telescopic length to meet specific combustion requirements, the operator stops the servo motor 161, keeping the central tube adjusting mechanism 1 in the adjusted position, ensuring that the burner can operate in optimal condition.

[0022] Working principle: First, the central tube adjusting mechanism 1 is installed inside the mixing section main pipe 2. Then, the sealing ring gasket 8 ensures a seal at the gasket joint. Next, the central tube telescopic section 13 is connected to the adjusting device 16 via studs. Then, the central piston tube 12 is sealed by the piston ring 14. Simultaneously, the slide rod assembly 15 is fixed at an appropriate position on the central tube telescopic section 13 and symmetrically welded at 60°. After ensuring a seal at both locations, it is ready for use. Then, the servo motor 161 is started, causing the adjusting shaft 168 to perform a 90° reciprocating rotation. The rotation of the adjusting shaft 168 is then converted into linear motion by the adjusting crank 167. Following the movement of the adjusting crank 167... The action causes the connecting rod 169 to push or pull the central tube telescopic section 13 to move, allowing it to slide within the mixing section main tube 2, thereby adjusting the length of the central tube. Simultaneously, the deep groove ball bearing 154 in the slide rod assembly 15 is connected to the slide rod fixing block 153 by bolts, reducing friction of the central tube telescopic section 13 during movement. At the same time, the piston ring 14 at the central piston tube 12 ensures that there is no gas leakage during the adjustment process. Then, when the central tube telescopic section 13 reaches the required telescopic length, the servo motor 161 stops working, keeping the central tube adjustment mechanism 1 in the adjusted position. Through the adjustment of the above-mentioned device, the burner can adapt to different combustion requirements, ensuring combustion efficiency and safety.
