Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to a combined nozzle for boiler burners. Background Technology

[0002] A boiler burner is a device used to ignite fuel and promote fuel-air mixing for efficient combustion, playing a central role in industrial and residential heating systems. The burner nozzle is a key component, responsible for atomizing the fuel and ensuring thorough mixing with air, thereby improving combustion efficiency and reducing pollution.

[0003] Existing nozzles are directly installed on the outer surface of the burner. However, the bottom surface of some boiler chambers is not flat, which can cause the burner to be installed unevenly, resulting in the nozzle shaking during use. This shaking not only affects the combustion effect, but also accelerates the wear of the nozzle and connecting parts. Therefore, it is necessary to provide a nozzle that can avoid the above-mentioned shaking and ensure the stable operation of the burner. Utility Model Content

[0004] The purpose of this utility model is to provide a combined nozzle for boiler burners to solve the problem mentioned in the background art, where existing nozzles are directly installed on the outer surface of the burner. However, the bottom surface of some boiler chambers is not flat, which can cause the burner to be installed unevenly, resulting in vibration during the use of the nozzle. This vibration not only affects the combustion effect but also accelerates the wear of the nozzle and connecting parts.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a combined nozzle for a boiler burner, comprising:

[0007] Main body assembly, including nozzle;

[0008] The support assembly includes a fixed frame, a horizontal display table, a limiting groove, a first threaded rod, and a first clamping block;

[0009] The fixed frame is fixed to one side of the outer surface of the nozzle, the horizontal display is installed on the upper surface of one side of the outer surface of the fixed frame, the limiting groove is opened on the upper surface of the inner side of the fixed frame, the first threaded rod passes through one side of the outer surface of the fixed frame, and the first clamping block is connected to one end of the outer surface of the first threaded rod.

[0010] Furthermore, a mounting flange is provided on one side of the outer surface of the nozzle, an air intake pipe is fixed on one side of the outer surface of the nozzle, and a combustion disc is installed inside the nozzle.

[0011] Furthermore, a second threaded rod passes through the other side of the fixed frame, a second clamping block is fixed to one side of the outer surface of the second threaded rod, a first electric push rod is installed on one side of the lower surface of the fixed frame, the output end of the first electric push rod is connected to a first pad, a second electric push rod is fixed to the other side of the lower surface of the fixed frame, and the output end of the second electric push rod is connected to a second pad.

[0012] Furthermore, the upper surfaces of the first clamping block and the second clamping block penetrate into the interior of the limiting groove, and the first clamping block and the second clamping block contact the outer surface of the nozzle.

[0013] Furthermore, it also includes cleaning components;

[0014] The cleaning components include a limit ring, a limit frame, a handle, and a scraper;

[0015] The limiting ring is fixed to one side of the nozzle's outer surface, the limiting frame is installed on the outer surface of the limiting ring, the handle is connected to the upper surface of the limiting frame, and the scraper is fixed to one side of the outer surface of the limiting frame.

[0016] Furthermore, the scraper contacts the inner wall of the nozzle, and the limiting frame makes a circular motion on the outer surface of the limiting ring.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] I. This utility model, through the setting of a fixed frame, a level indicator, a limiting groove, a first threaded rod, a first clamping block, a second threaded rod, a second clamping block, a first electric push rod, a first pad, a second electric push rod, and a second pad, allows the operator to directly insert the fixed frame into the outer surface of the nozzle from above when installing the nozzle on the boiler burner, in order to avoid unstable nozzle installation. Then, the operator holds the first and second threaded rods and rotates them, causing the first and second clamping blocks to move towards the center and clamp the nozzle. Next, the operator observes whether the level indicator and fixed frame are level. Based on the level indicator and through an external control module, the first and second electric push rods are activated, extending and retracting to adjust the level of the fixed frame. This not only ensures the correct installation and positioning of the nozzle but also improves the operating efficiency and reliability of the burner through a precise adjustment mechanism, extending the service life of the equipment.

[0019] II. Based on the first beneficial effect, by setting a limiting ring, limiting frame, handle, and scraper, when the nozzle needs to be cleaned after a period of use, the staff can directly hold the handle and rotate it around the outer surface of the nozzle. The handle will simultaneously rotate the limiting frame, and the rotation of the limiting frame will drive the scraper to rotate, cleaning the carbon deposits at the nozzle tip. It can adapt to the shape of the nozzle tip, effectively remove carbon deposits and dirt, and protect the nozzle surface from damage. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] Please see Figures 1-3 As shown, this embodiment is a combined nozzle for a boiler burner, comprising:

[0034] The main component includes a nozzle 11;

[0035] A mounting flange 12 is fixed to the outer surface of the nozzle 11, an air inlet pipe 13 is fixed to one side of the outer surface of the nozzle 11, and a combustion disc 14 is installed inside the nozzle 11.

[0036] Nozzle 11 is one of the key components of the burner, responsible for spraying fuel in an atomized form and mixing it fully with air to ensure rapid and complete combustion. Inlet pipe 13 is fixed to one side of the outer surface of nozzle 11 and is responsible for supplying the necessary combustion air into the burner. Combustion disc 14 is installed inside nozzle 11 to further promote the uniform mixing of fuel and air and ensure more complete combustion.

[0037] The support assembly includes a fixed frame 21, a horizontal display 211, a limiting groove 22, a first threaded rod 23, and a first clamping block 24. The fixed frame 21 is fixed to one side of the outer surface of the nozzle 11, the horizontal display 211 is installed on the upper surface of one side of the outer surface of the fixed frame 21, the limiting groove 22 is opened on the upper surface of the inner side of the fixed frame 21, the first threaded rod 23 passes through one side of the outer surface of the fixed frame 21, and the first clamping block 24 is connected to one end of the outer surface of the first threaded rod 23.

[0038] A level indicator 211 is mounted on the upper surface of the outer surface of the fixed frame 21 to indicate whether the fixed frame 21 is in a horizontal state.

[0039] The limiting groove 22 is formed on the inner upper surface of the fixed frame 21 to limit the range of motion of the first clamping block 24 and the second clamping block 26;

[0040] The first threaded rod 23 passes through one side of the outer surface of the fixed frame 21 and is used to adjust the position of the first clamping block 24. The second threaded rod 25 is located on the other side of the fixed frame 21 and is used to adjust the position of the second clamping block 26.

[0041] A second threaded rod 25 passes through the other side of the fixed frame 21. A second clamping block 26 is fixed to one side of the outer surface of the second threaded rod 25. A first electric push rod 27 is installed on one side of the lower surface of the fixed frame 21. A first pad 271 is connected to the output end of the first electric push rod 27. A second electric push rod 28 is fixed to the other side of the lower surface of the fixed frame 21. A second pad 281 is connected to the output end of the second electric push rod 28.

[0042] The first electric push rod 27 is installed on one side of the lower surface of the fixed frame 21 to provide power output. The extension and retraction of the first electric push rod 27 finely adjusts the angle of the nozzle 11.

[0043] The second electric push rod 28 is fixed on the other side of the lower surface of the fixed frame 21 and is used in conjunction with the first electric push rod 27. The power output provided by the second electric push rod 28 can be transmitted to the nozzle 11 through the connected second pad 281, thereby realizing the horizontal adjustment of the nozzle 11.

[0044] Working principle:

[0045] When nozzle 11 is installed on the boiler burner;

[0046] First, to avoid the nozzle 11 being installed unevenly, the staff can directly insert the fixing frame 21 into the outer surface of the nozzle 11 from above;

[0047] At this time, the staff holds the first threaded rod 23 and the second threaded rod 25, and rotates the first threaded rod 23 and the second threaded rod 25, which drives the first clamping block 24 and the second clamping block 26 to move inward and clamp the nozzle 11.

[0048] Next, observe whether the level display 211 and the fixed frame 21 are level. According to the level display 211, and through the external controller, the first electric push rod 27 and the second electric push rod 28 are extended and retracted to adjust the level of the fixed frame 21.

[0049] This step not only ensures the correct installation and positioning of nozzle 11, but also improves the operating efficiency and reliability of the burner through a fine adjustment mechanism, thus extending the service life of the equipment.

[0050] Please see Figure 4 As shown, this embodiment, based on embodiment 1 above, further includes:

[0051] Clean up components;

[0052] The cleaning components include a limiting ring 31, a limiting frame 32, a handle 33, and a scraper 34;

[0053] The limiting ring 31 is fixed to one side of the outer surface of the nozzle 11, the limiting frame 32 is installed on the outer surface of the limiting ring 31, the handle 33 is connected to the upper surface of the limiting frame 32, and the scraper 34 is fixed to one side of the outer surface of the limiting frame 32.

[0054] The handle 33 is designed to provide a comfortable grip and sufficient leverage, allowing operators to easily control the movement of the scraper 34, thereby reducing labor intensity and improving cleaning efficiency;

[0055] As the handle 33 rotates, the limiting frame 32 also rotates synchronously. As an intermediate structure connecting the handle 33 and the scraper 34, the limiting frame 32 ensures the stability and synchronization of the entire cleaning assembly.

[0056] Working principle:

[0057] After the nozzle 11 has been used for a period of time;

[0058] First, the front end of nozzle 11 needs to be cleaned. At this time, the staff should directly hold handle 33.

[0059] Next, the handle 33 is rotated around the outer surface of the nozzle 11, and the handle 33 simultaneously drives the limiting frame 32 to rotate.

[0060] The rotation of the limiting frame 32 will cause the scraper 34 to rotate, cleaning the carbon deposits at the front end of the nozzle 111;

[0061] This step adapts to the shape of the nozzle tip 11, effectively removing carbon deposits and dirt while protecting the nozzle 11 surface from damage.
