Description

Technical Field

[0001] This utility model relates to the field of burner technology, specifically to a burner that is easy to disassemble. Background Technology

[0002] In the fields of industrial production and energy supply, burners, as core equipment for achieving efficient fuel conversion, are widely used in various thermal devices such as boilers, heating furnaces, and hot blast stoves. Their performance directly affects energy utilization, production stability, and emission standards; therefore, a stable combustion state must be maintained during long-term operation.

[0003] However, during operation, burners are prone to incomplete combustion due to factors such as fuel quality variations, air-fuel ratio fluctuations, and uneven combustion temperature distribution. Unburned fuel particles, hydrocarbons, and sulfides gradually accumulate on the inner wall of the burner head and the surface of the flame stabilizer, forming deposits such as carbon deposits, coke, and corrosive scale. As operating time increases, the deposit thickness grows, not only reducing the cross-section of the combustion channel and obstructing airflow, leading to flame distortion and decreased combustion efficiency, but also potentially causing localized overheating and flame deviation. In severe cases, it can even cause burner backfire and deflagration, exacerbating emissions of pollutants such as nitrogen oxides and carbon monoxide, failing to meet environmental protection requirements.

[0004] To avoid the above problems, burners require regular cleaning and maintenance, especially the thorough removal of deposits from the burner head and flame stabilizer. However, most burners on the market currently have significant structural design flaws, leading to numerous difficulties in maintenance:

[0005] Traditional burners typically employ a one-piece structure or a rigid connection via multiple bolts. Disassembly requires tightening each bolt individually, a cumbersome and time-consuming process. Some burners' bolts deform due to prolonged exposure to high temperatures, further complicating disassembly and potentially damaging components if forced. The flame stabilizer, a critical combustion component, is usually fixed deep within the burner head and lacks convenient access. Maintenance personnel must remove multiple external components to reach the flame stabilizer, extending maintenance time and potentially affecting assembly precision during repeated disassembly, thus reducing burner operational stability.

[0006] In addition, the existing burner's structural design makes it difficult to fully expose the inner wall of the burner head, making it impossible to thoroughly clean the inner wall during cleaning. The residual deposits will accelerate the formation of scale next time, shorten the maintenance cycle, and increase operating costs. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A detachable burner includes a burner body 1, with a circular mixing chamber 2 connected to the output end of the burner body 1, and further includes:

[0029] The burner head 3 is a cylindrical structure made of refractory metal. The burner head 3 is horizontally set on the opening side of the circular mixing chamber 2. The burner head 3 is equipped with a flame stabilizer plate 4 and a flame stabilizer plate fixing structure.

[0030] The burner head quick-release fixing component 5 is sleeved on the outside of the burner head 3, and the burner head 3 is fixed to the opening side of the circular mixing chamber 2 by the burner head quick-release fixing component 5. This utility model does not limit the specific models of the burner body 1, the circular mixing chamber 2 and the flame stabilizer 4, as long as they are models commonly used by those skilled in the art.

[0031] Furthermore, a support block 6 is provided below the quick-release fixing assembly 5 of the burner head. The support block 6 provides support to prevent deformation of the circular mixing chamber 2 and the burner head 3 due to the increased weight of the quick-release fixing assembly 5 of the burner head.

[0032] Furthermore, the burner head 3 includes a first burner head 7 and a second burner head 8, and the first burner head 7 and the second burner head 8 are completely symmetrical about a vertical plane passing through the axis. The first burner head 7 and the second burner head 8 are identical, which facilitates installation and replacement after damage. The first burner head 7 and the second burner head 8 are set vertically. If they are set horizontally, they are prone to loosening due to gravity. The degrees of freedom of the first burner head 7 and the second burner head 8 are locked by vertical constraints (this is common knowledge). If they are set horizontally, the fixing structure (lower block 16 and upper block 17) can only be set vertically, which will cause the second pin 22 to be horizontal, and the pin may slip out.

[0033] Furthermore, a mating boss is provided on the side of the burner head 3 adjacent to the circular mixing chamber 2. Adjacent to the mating bosses of the first burner head 7 and the second burner head 8, mating ridges 9 are provided. First pin holes 10 are formed on the mating ridges 9, and first pins 11 are installed within the first pin holes 10. The first burner head 7 and the second burner head 8 are mated together by multiple sets of first pins 11. Since the existing circular mixing chamber 2 has flanges on both sides, it is recommended that the mating boss be designed to fit the shape of the flanges of the circular mixing chamber 2. This would make the slot 18 easier to machine, and the first pins 11 would prevent axial misalignment of the first burner head 7 and the second burner head 8.

[0034] Furthermore, the flame stabilizing disc fixing structure includes two symmetrical first semicircular grooves 12 and second semicircular grooves 13. The first semicircular groove 12 is located inside the first burner head 7, and the second semicircular groove 13 is located inside the second burner head 8. The flame stabilizing disc 4 is engaged between the first semicircular groove 12 and the second semicircular groove 13. After the first semicircular groove 12 and the second semicircular groove 13 are joined together, they form a recessed groove, which can just hold the disc-shaped flame stabilizing disc 4.

[0035] Furthermore, the inner sides of the first semicircular groove 12 and the second semicircular groove 13 are provided with opposing grooves 15, and the flame stabilizer 4 is provided with two sets of opposing square protrusions 14, which are engaged in the grooves 15. The square protrusions 14 and the grooves 15 can prevent the flame stabilizer 4 from rotating.

[0036] Furthermore, the quick-release fixing assembly 5 for the burner head includes a lower block 16 and an upper block 17. The lower block 16 is positioned below the burner head 3, and the upper block 17 is positioned above the burner head 3. The lower block 16 and the upper block 17 are hinged together. Both the lower block 16 and the upper block 17 are provided with slots 18 corresponding to the circular mixing chamber 2 and the burner head 3. The circular mixing chamber 2 and the burner head 3 are initially fixed by being engaged in the slots 18. The plate-shaped fixing ears 19 and the locking sleeve 20 fix the lower block 16 and the upper block 17. If it is necessary to release the fixing of the circular mixing chamber 2 and the burner head 3, it is necessary to release the fixing of the lower block 16 and the upper block 17.

[0037] Furthermore, two sets of plate-shaped fixing ears 19 are provided on the side of the lower cover block 16 and the upper cover block 17 away from the hinge. One set of plate-shaped fixing ears 19 is fixedly connected to the lower cover block 16, and the other set of plate-shaped fixing ears 19 is fixedly connected to the upper cover block 17. Locking sleeves 20 are sleeved on the outside of the two sets of plate-shaped fixing ears 19. Square through slots corresponding to the two sets of plate-shaped fixing ears 19 are opened in the locking sleeve 20. Through-hole second pin holes 21 are opened on the locking sleeve 20 and the plate-shaped fixing ears 19. Second pins 22 are provided in the second pin holes 21. The second pins 22 pass through the upper surface of the locking sleeve 20, the two sets of plate-shaped fixing ears 19 and the lower surface of the locking sleeve 20 in sequence. After the two sets of plate-shaped fixing ears 19 are fitted together, the locking sleeve 20 can slide and lock onto the two sets of plate-shaped fixing ears 19. The second pin 22 can be used to fix the locking sleeve 20 onto the two sets of plate-shaped fixing ears 19, which can prevent loosening. It is also very convenient to remove the fixing operation. After removing the second pin 22, the locking sleeve 20 can be removed. At this time, the upper package block 17 can be rotated to remove the burner head 3. The first pin 11 is removed again to complete the separation of the burner head 3. At this time, cleaning and maintenance operations can be performed.

It is used to fix the locking sleeve 20 and the plate-shaped fixing ears 19, thereby locking the lower block 16 and the upper block 17.

[0061] Working principle: The device is based on a modular quick-release structure design, and the burner head 3 can be quickly disassembled and maintained through multiple combined fixed connections. The whole device is based on the burner body 1, the circular mixing chamber 2 and the horizontally set burner head 3 form a fuel combustion passage, and the burner head quick-release fixing component 5 serves as the core connection mechanism to realize the quick fixing and separation of the burner head 3 and the circular mixing chamber 2.

[0062] The burner head 3 is vertically assembled from a completely symmetrical first burner head 7 and a second burner head 8. The two are rigidly connected to the first pin 11 through the first pin hole 10 on the mating cam 9 to prevent axial displacement. The assembled burner head 3 is precisely mated to the flange of the circular mixing chamber 2 through the mating cam. The burner head quick-release fixing assembly 5, composed of the lower package 16 and the upper package 17, is fixed on the outside. The lower package 16 and the upper package 17 are closed by a hinge structure. The internal slot 18 fits the shape of the circular mixing chamber 2 and the burner head 3 to form a preliminary positioning. After the two sets of plate-shaped fixing ears 19 opposite to the hinge are fitted together, the locking sleeve 20 is put on and the second pin 22 is inserted to complete the overall locking through the through-type fixing. At the same time, the lower support block 6 provides load-bearing support to avoid structural deformation under high temperature environment.

[0063] The flame stabilizer 4 is fixed by an embedded design, with its edge engaging in the annular groove formed by the first semicircular groove 12 and the second semicircular groove 13 on the inner side of the first burner head 7 and the second burner head 8. The cooperation of the two sets of square protrusions 14 with the corresponding grooves 15 restricts the circumferential rotation of the flame stabilizer 4, ensuring the stability of the airflow during combustion.

[0064] When maintenance is required, the operator can complete the disassembly without tools: first, pull out the second pin 22 and remove the locking sleeve 20, then flip the upper block 17 around the hinge axis to unlock the quick-release fixing assembly 5 of the burner head; then pull out the first pin 11 to separate the first burner head 7 and the second burner head 8 vertically. At this time, the inner wall of the burner head 3 is completely exposed, which is convenient for cleaning carbon deposits and other attachments; at the same time, the separated burner head 3 makes the flame stabilizer plate 4 lose its lateral restraint and can be directly removed from the semi-circular groove for thorough cleaning or replacement.

[0065] After maintenance, quick assembly can be achieved by reversing the steps: align the square protrusion 14 of the flame stabilizer 4 with the groove 15 and place it into the semi-circular groove; assemble the first burner head 7 and the second burner head 8 and insert the first pin 11 to complete the connection; close the lower cover block 16 and the upper cover block 17, so that the slot 18 covers the connection between the burner head 3 and the circular mixing chamber 2; put on the locking sleeve 20 and insert the second pin 22 to complete the fixation. The entire process achieves positioning and locking through the mechanical cooperation of the pin and the slot 18, avoiding the cumbersome operation of traditional bolt connections, significantly improving maintenance efficiency. At the same time, the symmetrical design ensures consistency in disassembly and assembly, ensuring the coaxiality and combustion stability of the burner head 3 after reassembly.

[0066] 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.
