Description

Technical Field

[0001] This utility model relates to the field of burner nozzles, specifically to an anti-clogging burner nozzle. Background Technology

[0002] In the long-term use of existing burner nozzles, combustion efficiency, energy utilization rate and emission control are directly related. The stability of nozzle performance will directly affect the uniformity of combustion effect and the safety of the system. Once the nozzle is worn or blocked, it will not only lead to incomplete combustion and increased energy consumption, but may also cause equipment failure or even safety accidents.

[0003] Regarding clogging prevention, when dust, oil, or other impurities are present in the combustion environment, these impurities can easily adhere directly to the nozzle head or filter holes. With increased usage time, these impurities can easily cause filter blockage, leading to poor gas flow. This not only affects combustion efficiency but may also cause safety hazards such as fluctuating flame size or even extinguishing due to unstable gas supply. At the same time, the fixed filter structure is difficult to clean after clogging, often requiring the disassembly of the entire nozzle for maintenance, which increases the complexity of operation and maintenance costs. Therefore, we have proposed a clogging-resistant burner nozzle. Utility Model Content

The spherical end of the spherical protrusion 8 is engaged with the spherical groove 7 outside the telescopic groove 13. The telescopic groove 13 is used to install the spring 14 and the spherical protrusion 8. The elastic force of the spring 14 causes the spherical protrusion 8 to extend and engage in the spherical groove 7, thereby fixing the position of the sleeve 4 and the telescopic rod 5. The distance between the filter plate 6 and the burner head body 1 can be adjusted according to different flame requirements.

[0032] Furthermore, the inner cylindrical surface of the fixing ring 3 is provided with an annular groove 15, which is located between the filter plate 6 and the head of the combustion head body 1. The annular groove 15 is used to install the adjustment hole structure.

[0036] Structural Description:

[0037] Burner head body 1: It is tubular or cylindrical and is the core component of the burner. It is used to spray out gas and form a flame, providing a basic carrier for combustion.

[0038] Internal threaded tube 2: It is tubular and has threads on the inner wall. It is sleeved on the outer surface of the burner head body 1 and close to the head. It is connected to the burner head body 1 by threads, providing fixed support for the anti-clogging structure and facilitating overall disassembly and assembly.

[0039] Fixed ring 3: It is ring-shaped and connected to the end of the telescopic rod 5. The inner side is used to install the filter plate 6. The inner cylindrical surface has an annular groove 15 to provide installation space for the adjustment hole structure and play a role in connection and bearing.

[0040] Sleeve 4: It is tubular, with multiple tubes fixed circumferentially at equal intervals to the side of the internally threaded tube 2 facing the head of the burner. The telescopic rod 5 can be inserted inside to provide guidance and support for the sliding of the telescopic rod 5.

[0041] Telescopic rod 5: It is a rod shape that fits the sleeve 4. One end is inserted into the sleeve 4 and the other end is connected to the fixing ring 3. It can slide inside the sleeve 4 and adjust the distance between the filter plate 6 and the burner body 1 in conjunction with the sleeve 4.

[0042] Filter plate 6: It is plate-shaped and fixed inside the fixing ring 3. The surface is distributed with multiple sets of linear filter holes evenly arranged in a circle, which can pass through the rated flame and block external impurities, reducing the risk of burner head clogging.

[0043] Spherical groove 7: It is a spherical groove, which is opened on the cylindrical surface of the sleeve 4. Multiple grooves are distributed at equal intervals along a straight line and located on the side of the sleeve 4 away from the burner head body 1. It is engaged with the spherical protrusion 8 and used to fix the relative position of the sleeve 4 and the telescopic rod 5.

[0044] Spherical protrusion 8: It is a block with a spherical end, connected to the end of the spring 14. Under the action of the spring force, it extends out of the telescopic groove 13 and engages with the spherical groove 7 to fix the position of the sleeve 4 and the telescopic rod 5.

[0045] Arc-shaped hole 9: An arc-shaped through hole, opened on the outer cylindrical surface of the fixing ring 3 and extending through to the annular groove 15, used to accommodate and guide the sliding of the push rod 10 and limit the rotation range of the push rod 10;

[0046] Push rod 10: It is rod-shaped, with one end connected to the mounting ring 11 and the other end slidably engaged with the arc-shaped hole 9. By sliding in the arc-shaped hole 9, it drives the mounting ring 11 and the blocking rod 12 to rotate.

[0047] Mounting ring 11: It is ring-shaped and is snapped into the annular groove 15 of the fixing ring 3. The inner ring surface is fixed with the blocking rod 12, and the outer ring surface is connected with the push rod 10. It can rotate in the annular groove 15 and is used to fix and drive the blocking rod 12.

[0048] Blocking rod 12: It is rod-shaped, multiple rods are evenly fixed to the inner ring surface of the mounting ring 11, and the number is the same as the number of filter holes in the filter plate 6. When the mounting ring 11 rotates, it can block the filter holes of the filter plate 6 and adjust the effective flow area of ​​the filter holes.

[0049] Telescopic groove 13: It is groove-shaped and is opened on the cylindrical surface of telescopic rod 5. Multiple grooves are distributed equidistantly along a straight line and correspond to the position of spherical groove 7. The inside is used to install spring 14 and spherical protrusion 8, providing space for both.

[0050] Spring 14: It is spiral-shaped and installed in the telescopic groove 13. One end is fixed to the bottom of the telescopic groove, and the other end is connected to the spherical protrusion 8. The spherical protrusion 8 is pushed by the elastic force to engage with the spherical groove 7 to ensure that the position is fixed.

[0051] Annular groove 15: It is an annular groove, which is opened on the inner cylindrical surface of the fixing ring 3 and located between the filter plate 6 and the head of the combustion head. It is used to snap the mounting ring 11 and provide a rotation track for the adjustment hole structure.

[0052] Working Principle: In the overall assembly, the internally threaded tube 2 is threadedly connected to the burner head body 1, providing support for the anti-clogging structure and facilitating overall disassembly and maintenance. The anti-clogging structure, through the insertion and cooperation of the sleeve 4 and the telescopic rod 5, mounts the fixing ring 3 and the filter plate 6 above the head of the burner head body 1. The filter plate 6 consists of multiple sets of evenly distributed linear filter holes, which not only allow the rated flame of the burner head body 1 to pass smoothly but also prevent external dust, oil, and other impurities from directly contacting the burner head, reducing the risk of clogging from the source. When it is necessary to adjust the distance between the filter plate 6 and the burner head body 1 according to the flame size or impurity situation, the adjustment is achieved through the sliding cooperation of the sleeve 4 and the telescopic rod 5. During the adjustment process, the spherical protrusion 8 on the telescopic rod 5 can be engaged into the spherical groove 7 at different positions on the sleeve 4 under the elastic force of the spring 14, thereby fixing the relative position of the two and ensuring the filter plate 6 The adjustable working spacing at a suitable distance can adapt to the injection requirements of different flame intensities. The adjustment hole structure is used to precisely control the effective filter hole size of the filter plate 6 to adapt to the flame requirements of different combustion scenarios. The mounting ring 11 is snapped into the annular groove 15 of the fixed ring 3. By pushing the push rod 10 in the arc-shaped hole 9, the mounting ring 11 can be rotated, which in turn causes the blocking rod 12 fixed on the inner annular surface of the mounting ring 11 to rotate synchronously. Since the number of filter hole rows of the filter plate 6 is the same as the number of blocking rods 12, the blocking rod 12 will partially or completely block the filter hole rows when it rotates, changing the actual flow area of ​​the filter holes. When a strong flame is required, the push rod 10 is rotated to completely offset the blocking rod 12 from the filter hole rows, allowing all the filter holes to open and increasing the gas flow. When a weak flame is required or to reduce the entry of impurities, the blocking rod 12 is adjusted to partially block the filter holes, limiting the flow area and achieving flexible adjustment of flame intensity.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
