Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a water-cooled flameless low-nitrogen burner. Background Technique

[0002] A burner is a general term for a device that sprays and mixes fuel and air for combustion. Burners are classified into industrial burners, combustion machines, domestic burners, and special burners according to types and application fields. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium metal. Burners are classified into fuel burners, gas burners, light oil burners, and dual-fuel burners according to the fuel method.

[0003] The water-cooled flameless low-nitrogen burner belongs to a kind of low-nitrogen burner. For example, the Chinese invention patent with the publication number of CN117212794A discloses a water-cooled flameless low-nitrogen burner, which includes a housing. One end of the housing is connected to the main air pipeline, and the other end of the housing is provided with a gas inlet. One end of the gas inlet is connected to the combustion chamber through a distribution pipe. A mixer is arranged in the combustion chamber. A distributor is arranged on one side of the mixer, and a porous support plate is arranged outside the distributor. Cooling coils are arranged outside the porous support plate.

[0004] When the low-nitrogen burner is in use, a flame stabilizing disc is usually arranged at one end of the combustion tube to improve the stability of the flame. However, most of the flame stabilizing discs are installed at one end of the combustion tube by welding. After the flame stabilizing disc is used in a high-temperature environment for a long time, it is easy to be damaged. When replacing it, the combustion tube needs to be replaced together, resulting in waste of materials and some inconvenience. Therefore, a water-cooled flameless low-nitrogen burner is proposed to solve the above problems. Content of the Utility Model

[0009] By adopting this technical solution, the fixed block can enter the interior of the fixed groove through the limit groove. After the fixed block and the limit groove are staggered, the fixed groove will limit the movement of the fixed block in the left and right directions. After the fixing rod and the fixed block are plugged in, the rotation of the fixed block can be further limited, thereby making the fixation of the flame stabilizing disk more stable.

[0010] Furthermore, a rubber pad is fixed to the bottom of the base plate, and flanges are fixed to the outer surfaces of the combustion-supporting fan and the mixing box.

[0011] By adopting this technical solution, the friction between the bottom plate and the ground can be increased by arranging the rubber pad, so that the support of the bottom plate can be more stable.

[0012] Furthermore, an ignition device is fixed on the front side of the combustion-supporting fan, and an identification plate is fixed on the front side of the ignition device.

[0013] By adopting this technical solution, the staff can be reminded through the set signboard, thereby preventing the staff from accidentally touching the ignition device and causing electric shock, thereby making the overall use safer.

[0014] Furthermore, the telescopic rod comprises an extension block fixed to the bottom plate, the top of the extension block is slidably connected to an extension rod fixed to the support platform, and the top of the extension block is fixed to a buffer spring.

[0015] By adopting this technical solution, when the telescopic rod is extended and retracted, the buffer spring will be squeezed, so that the vibration generated by the operation of the combustion-supporting fan can be buffered to a certain extent, making the whole more practical.

[0016] Furthermore, a threaded strip is fixed on the outer surface of the fixing rod, and a threaded hole matching the threaded strip is provided inside the mounting block.

[0017] By adopting this technical solution, the threaded strips and threaded holes are arranged so that when the fixing rod is rotated, the fixing rod will move simultaneously due to the squeezing of the threads.

[0018] Furthermore, a fixing groove is provided on the right side of the mounting block, and a limiting groove communicating with the fixing groove is provided on the right side of the mounting block.

[0019] By adopting this technical solution, the set fixing groove is used to position the fixing block, and the set limiting groove enables the fixing block to move into the interior of the fixing groove.

[0020] Furthermore, the inner cavities of the combustion-supporting fan, the mixing box, the intake pipe and the combustion cylinder are interconnected.

[0021] Furthermore, a sealing block is fixed on the left side of the flame-stabilizing disc, and a sealing groove adapted to the sealing block is provided on the right side of the combustion cylinder.

[0022] By adopting this technical solution, the set sealing block and the sealing groove can effectively improve the sealing performance at the connection between the flame-stabilizing disc and the combustion cylinder.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] 1. For this water-cooled flameless combustion low-nitrogen burner, when the flame-stabilizing disc needs to be replaced, after rotating the fixing rod inside the connection assembly, the flame-stabilizing disc can be rotated, so that after rotating the flame-stabilizing disc, the flame-stabilizing disc can be disassembled, and then the flame-stabilizing disc can be conveniently replaced without replacing the whole combustion cylinder, thus effectively reducing the waste of materials and making the whole more practical.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1 , in this embodiment, a water-cooled flameless combustion low-nitrogen burner includes a bottom plate 1. A rubber pad is fixed to the bottom of the bottom plate 1. By providing the rubber pad, the friction between the bottom plate 1 and the ground can be increased, so that the support of the bottom plate 1 can be more stable. A combustion-supporting fan 2 is fixed to the top of the bottom plate 1. The provided combustion-supporting fan 2 is used to draw air into the mixing box 3.

[0032] In addition, an ignition device 12 is fixed to the front of the combustion-supporting fan 2, and a signboard is fixed to the front of the ignition device 12. By providing the signboard, it can prompt the staff, thus preventing the staff from accidentally touching the ignition device 12 and causing electric shock, and further making the overall use safer. A mixing box 3 is fixed to the right side of the combustion-supporting fan 2. Flange plates 11 are fixed to the outer surfaces of both the combustion-supporting fan 2 and the mixing box 3. An air inlet pipe 4 is fixed to the bottom of the mixing box 3. By providing the air inlet pipe 4, gas can enter the interior of the mixing box 3. A combustion cylinder 5 is fixed to the right side of the mixing box 3.

[0033] Furthermore, a connection component 6 is arranged on the outer surface of the combustion cylinder 5. A support plate 7 fixed to the mixing box 3 is fixed to the top of the bottom plate 1. A support platform 8 fixed to the combustion-supporting fan 2 is fixed to the top of the bottom plate 1. A telescopic rod 9 is fixed between the support platform 8 and the bottom plate 1. When the surface of the support platform 8 vibrates, the telescopic rod 9 will expand and contract. A buffer spring 10 fixed to the support platform 8 is fixed to the top of the telescopic rod 9. The telescopic rod 9 includes an extension block fixed to the bottom plate 1, and an extension rod fixed to the support platform 8 is slidably connected to the top of the extension block. The top of the extension block is fixed to the buffer spring 10. When the telescopic rod 9 expands and contracts, the buffer spring 10 will be compressed, so that the vibration generated during the operation of the combustion-supporting fan 2 can be buffered to a certain extent, making the overall more practical.

[0034] It should be noted that the inner cavities of the combustion-supporting fan 2, the mixing box 3, the air inlet pipe 4, and the combustion cylinder 5 are interconnected.

[0035] Generally speaking, the provided support platform 8 can support the combustion-supporting fan 2, making the combustion-supporting fan 2 more stable. And when the combustion-supporting fan 2 operates and the surface of the support platform 8 vibrates, the buffer spring 10 can buffer the vibration to a certain extent, making the overall more stable.

[0036] See also Figures 2 to 3 The connecting assembly 6 in this embodiment includes a mounting block 601, two fixing blocks 602, two connecting blocks 603, a flame stabilizing disk 604 and two fixing rods 605. The outer surface of the combustion tube 5 is fixed to the mounting block 601, and the interior of the mounting block 601 is slidably connected to the fixing block 602 that passes through the right side of the mounting block 601. The opposite sides of the two fixing blocks 602 are fixed to the connecting block 603, and the two connecting blocks 603 are fixed to the flame stabilizing disk 604. The flame stabilizing disk 604 fits the combustion tube 5. A sealing block 606 is fixed to the left side of the flame stabilizing disk 604, and a sealing groove matched with the sealing block 606 is opened on the right side of the combustion tube 5. The sealing block 606 and the sealing groove can effectively improve the sealing of the connection between the flame stabilizing disk 604 and the combustion tube 5.

[0037] In addition, the left side of the mounting block 601 is threadedly connected to the fixing rod 605 inserted into the fixing block 602, and a threaded strip is fixed to the outer surface of the fixing rod 605. The interior of the mounting block 601 is provided with a threaded hole that is compatible with the threaded strip. The threaded strip and the threaded hole are arranged so that when the fixing rod 605 is rotated, the fixing rod 605 will move simultaneously due to the squeezing of the thread. A fixing groove 607 is arranged on the right side of the mounting block 601. A limiting groove 608 connected to the fixing groove 607 is arranged on the right side of the mounting block 601. The fixing groove 607 is arranged to position the fixing block 602, and the limiting groove 608 is arranged so that the fixing block 602 can move to the inside of the fixing groove 607.

[0038] In general, the fixed block 602 can enter the interior of the fixed groove 607 through the limiting groove 608. After the fixed block 602 is staggered with the limiting groove 608, the fixed groove 607 will limit the movement of the fixed block 602 in the left and right directions. After the fixing rod 605 is plugged into the fixed block 602, the rotation of the fixed block 602 can be further limited, thereby making the fixation of the flame stabilizing plate 604 more stable.

[0039] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0040] The working principle of the above embodiment is:

[0041] When it is necessary to disassemble the flame stabilizing disc 604, by rotating the fixing rod 605, the fixing rod 605 can be moved simultaneously due to the extrusion of the thread, and then the fixing rod 605 moves to the side away from the fixing block 602, so that the fixing rod 605 loses the plug connection with the fixing block 602, enabling the fixing block 602 to move inside the fixing groove 607. At this time, by rotating the flame stabilizing disc 604, the connecting block 603 and the fixing block 602 can be moved. When the fixing block 602 moves to coincide with the limiting groove 608, the flame stabilizing disc 604 can be pulled to the right, so that the fixing block 602 moves to the outside of the mounting block 601 through the limiting groove 608, thus completing the disassembly of the flame stabilizing disc 604. The installation of the flame stabilizing disc 604 is the same in principle. The overall structure is simple, making the flame stabilizing disc 604 easy to install and disassemble, so that it is not necessary to replace the entire combustion cylinder 5, making the whole more practical.
