Description

Technical Field

[0001] This utility model relates to the field of burners, and more specifically to a combustion device. Background Technology

[0002] In outdoor activities, people often choose biomass pellet heaters. These heaters generate heat by burning biomass pellets. Inside the heater is a fixed, non-removable combustion mesh. This means that over time, biomass pellets and dust easily adhere to the mesh, resulting in extremely poor combustion efficiency and severely impacting the heating effect. Cleaning the mesh can only be done by inserting a cleaning rod through the feed hole, a time-consuming, laborious, and inconvenient method. Furthermore, if the mesh is damaged, repairs can only be made through the feed hole, or the entire heater can be replaced, making repairs difficult due to limited space. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a combustion device in which the feed pipe, combustion pipe, and air inlet pipe are connected to form a combustion chamber.

[0037] refer to Figure 1 and Figure 2 This utility model provides a combustion device, including a pipe body 1 and a combustion mesh frame 2. The pipe body 1 includes a feed pipe 11, a combustion pipe 12 and an air inlet pipe 13 that are connected to form a combustion chamber 10. The air inlet pipe 13 is provided with a first disassembly hole 130. The combustion mesh frame 2 is adapted to reach the combustion chamber 10 after passing through the first disassembly hole 130, so that the combustion mesh frame 2 can be detachably installed inside the pipe body 1.

[0038] In this embodiment, the feed pipe 11, combustion pipe 12 and air intake pipe 13 are connected to form a combustion chamber 10. The combustion mesh frame 2 can be detachably installed in the combustion chamber 10 of the pipe body 1 through the first disassembly hole 130 of the air intake pipe 13, which facilitates the cleaning, maintenance and replacement of the disassembled combustion mesh plate and extends the service life of the combustion equipment.

[0039] Specifically, the combustion device mainly consists of a pipe body 1 and a combustion frame 2. The pipe body 1 is formed by the interconnection of three parts: a feed pipe 11, a combustion pipe 12, and an air intake pipe 13, which together constitute a closed combustion chamber 10 with clearly defined functional zones. The feed pipe 11 is used to precisely deliver fuel into the combustion chamber 10. A transparent pipe 15 is installed on the combustion pipe 12 to provide a stable environment for the fuel combustion process while forming a flame column from the transparent pipe 15. The air intake pipe 13 is responsible for supplying an appropriate amount of combustion air to the combustion chamber 10 to ensure efficient combustion. The cross-sections of the feed pipe 11, combustion pipe 12, and air intake pipe 13 are not further limited in this application. The air intake pipe 13 is provided with a first disassembly hole 130, through which the combustion frame 2 can smoothly enter the combustion chamber 10 and be precisely installed. The combustion mesh frame 2 plays a crucial role in the combustion chamber 10. It not only evenly distributes the fuel but also effectively supports it, ensuring full contact between the fuel and the combustion air, thereby achieving efficient and stable combustion. Furthermore, the combustion mesh frame 2 is detachable, allowing for easy installation, replacement, repair, or maintenance via the first disassembly hole 130. This significantly improves the flexibility and ease of maintenance of the combustion equipment, reduces maintenance costs, and extends its service life.

[0040] Further, refer to Figures 2 to 4The first disassembly hole 130 is provided at the end of the air intake pipe 13 away from the combustion chamber 10; the combustion frame 2 includes an installation part 21 and a combustion part 22, the combustion part 22 is provided at one end of the installation part 21, the installation part 21 is adapted to be installed on the inner side wall of the air intake pipe 13 and the combustion part 22 is provided at the bottom of the feed pipe 11 and the combustion pipe 12.

[0041] In this embodiment, the first disassembly hole 130 is located at the end of the air intake pipe 13 away from the combustion chamber 10. The mounting part 21 precisely positions the combustion part 22 at the bottom of the feed pipe 11 and the combustion pipe 12, making the installation and disassembly of the combustion grid 2 more convenient and improving the safety and convenience of the operation.

[0042] Specifically, the combustion frame 2 includes a mounting part 21 and a combustion part 22, wherein the combustion part 22 is located at one end of the mounting part 21 and has several through holes. The mounting part 21 is adapted to push the combustion part 22 into the air intake pipe 13 and precisely position it at the bottom of the feed pipe 11 and the combustion pipe 12; at the same time, the mounting part 21 is also fitted onto the inner wall of the air intake pipe 13. This not only ensures the stable fixation of the combustion frame 2 in the combustion chamber 10, but also allows the combustion part 22 to fully exert its function, promoting the full mixing and combustion of fuel and combustion air. In actual operation, fuel enters the combustion chamber 10 through the feed pipe 11, while combustion air enters through the air intake pipe 13. The combustion part 22 of the combustion frame 2 is located at the bottom of the feed pipe 11 and the combustion pipe 12, which can effectively support the fuel and distribute it evenly in the bottom area of ​​the combustion chamber 10. Meanwhile, the mounting part 21 of the combustion grid 2 is firmly fixed to the inner wall of the air intake pipe 13, ensuring the stability of the combustion grid 2 in the high-temperature combustion environment and avoiding displacement or damage due to vibration or fuel impact during the combustion process.

[0043] In this application, a pair of mounting parts 21 are symmetrically arranged on both sides of the combustion section 22 and are adapted to be fixedly abutted against the inner wall of the air intake pipe 13. An air passage is left between the pair of mounting parts 21 to facilitate the replenishment of air to the combustion section 22. The mounting parts 21 are fixed to the inner wall of the air intake pipe 13 in various ways. In this application, the mounting parts 21 are also provided with a first fixing hole 211, and the air intake pipe 13 is provided with a corresponding second fixing hole 131. The first fixing hole 211 is adapted to be fixedly connected to the second fixing hole 131. The mounting parts 21 are also provided with a pull-out part 212, which is used to pull the combustion mesh frame 2 out of the air intake pipe 13. More specifically, the mounting part 21 is also provided with a first fixing hole 211, and the air intake pipe 13 is provided with a corresponding second fixing hole 131. The first fixing hole 211 is suitable for fixed connection with the second fixing hole 131 by fasteners (such as bolts, screws, or pins), thereby realizing the stable installation of the combustion grid 2 in the air intake pipe 13. This not only ensures the stability of the combustion grid 2 at high temperatures and during combustion, but also effectively prevents displacement or loosening caused by vibration or fuel impact, ensuring the normal operation of the combustion equipment. It is worth noting that the mounting part 21 can also be fixed by means of snap-fit, mutual abutment, or other structures. This application does not make further limitations here, as these are all within the protection scope of this application.

[0044] Preferably, the mounting part 21 is further provided with a pull part 212, which is used to pull the combustion mesh frame 2 out of the first disassembly hole 130 of the air inlet pipe 13. This method greatly improves the ease of disassembly of the combustion mesh frame 2, reduces maintenance time and labor intensity, and also reduces operational risks, avoiding burns to users when disassembling the combustion mesh frame 2, and ensuring that the equipment maintenance process is safer and more efficient. The form of the pull part 212 in this application is diverse, and no further limitation is made here. For example, the pull part 212 is a structure such as a pull ring, pull handle, or pull rod that is easy to operate. When the pull part 212 is pulled, the combustion mesh frame 2 can be easily pulled out of the air inlet pipe 13 for maintenance, replacement, or cleaning. Alternatively, the pull part 212 can be a pull hole, a nut, or the first fixing hole 211. The pull rod is adapted to extend into the first disassembly hole 130 and insert into the pull hole of the pull part 212, and the combustion mesh frame 2 is pulled outward by the pull rod. The pull-out part 212 can be entirely located inside the air intake pipe 13 or partially located inside the air intake pipe 13, with the remaining part extending out of the first disassembly hole 130. This application does not make any further limitations here.

[0045] In a modified embodiment, the first disassembly hole 130 is disposed on the end side wall of the intake pipe 13. The first disassembly hole 130 needs to correspond to the vertical cross-section of the combustion mesh frame 2. Since the vertical cross-section of the combustion mesh frame 2 is relatively small, it is easier to push the combustion mesh frame 2 horizontally. Furthermore, the combustion section 22 can more easily reach the bottom of the feed pipe 11 and the combustion pipe 12 during pushing. Therefore, this application preferably places the first disassembly hole 130 at the end of the intake pipe 13 away from the combustion chamber 10. Of course, the first disassembly hole 130 can also be located at other positions on the intake pipe 13. For example, the first disassembly hole 130 can also be located at the top, bottom, or left and right sides of the intake pipe 13. However, in this case, the first disassembly hole 130 needs to correspond to the horizontal cross-section of the combustion mesh frame 2, and the pushing direction of the combustion mesh frame 2 may be inclined. This application will not further elaborate or limit the position of the first disassembly hole 130 or the pushing direction of the combustion mesh frame 2; these are all within the scope of protection of this application.

[0046] Furthermore, the air intake pipe 13 is adapted to be horizontally arranged, and the feed pipe 11 includes a first pipe 111, which is adapted to be inclinedly arranged above the air intake pipe 13. The first pipe 111 and the air intake pipe 13 have a first connection point 1111 and a second connection point 1112. The combustion part 22 of the combustion grid 2 is adapted to be inclinedly arranged between the first connection point 1111 and the second connection point 1112.

[0047] In this embodiment, the combustion section 22 of the combustion frame 2 is adapted to be inclinedly arranged between the first connection point 1111 and the second connection point 1112, so that the combustion section 22 can form an optimal angle match with the fuel entry direction and the combustion air flow direction. This not only improves the performance of the combustion equipment, but also ensures that when the combustion frame 2 is removed, the combustion particles will automatically fall along the inclined combustion section 22 and extinguish the flame, making the disassembly process of the combustion frame 2 safer.

[0048] Specifically, the intake pipe 13 is horizontally positioned to ensure that the combustion air can enter the combustion chamber 10 smoothly and evenly, providing stable airflow support for the combustion process. In this case, the first disassembly hole 130 serves as the intake port. The feed pipe 11 includes an inclined first pipe 111, located above the intake pipe 13, forming a specific spatial arrangement with it. Specifically, the first pipe 111 and the intake pipe 13 form an angle. This arrangement allows fuel to smoothly enter the combustion chamber 10 along the first pipe 111 while preventing direct fuel impact on the intake pipe 13, thus reducing interference with the flow of combustion air. There are two connection points between the first pipe 111 and the intake pipe 13: a first connection point 1111 and a second connection point 1112. The first connection point 1111 and the second connection point 1112 not only realize the structural connection between the first pipe 111 and the intake pipe 13, but also together form part of the combustion chamber 10, so that the fuel and combustion air can be fully mixed and carried out combustion reaction in the combustion chamber 10, and also enhance the stability of the entire pipe body 1 structure, while providing precise spatial positioning for the installation of the combustion grid 2.

[0049] The combustion section 22 of the combustion frame 2 is adapted to be inclined between the first connection point 1111 and the second connection point 1112. In this configuration, the combustion section 22 can achieve an optimal angular alignment with the fuel entry direction and the combustion air flow direction. On one hand, the inclined combustion section 22 can better guide fuel distribution, ensuring it is evenly distributed at the bottom of the combustion chamber 10. On the other hand, the inclination angle of the combustion section 22 can be optimized according to combustion requirements, for example, by adjusting the angle to improve combustion efficiency, reduce pollutant emissions, or reduce the unevenness of combustion temperature distribution. Furthermore, the inclination angle of the combustion section 22 can be fine-tuned according to actual operating conditions to adapt to different fuel types and combustion conditions. For example, for small particulate fuels, the inclination angle can be appropriately increased to prevent fuel accumulation; while for large particulate fuels, the inclination angle can be appropriately decreased to ensure sufficient mixing of fuel and combustion air. At this time, the tilt angle of the combustion section 22 and the detachable nature of the combustion grid 2 complement each other. That is, by replacing the combustion grid 2, the tilt angle of the combustion section 22 can be adjusted to adapt to different fuel types and combustion conditions, providing greater flexibility and adaptability for the operation and maintenance of the equipment. This enables the combustion equipment to be widely used in a variety of combustion scenarios and has high versatility and practicality.

[0050] Furthermore, when the combustion mesh frame 2 is removed, the combustion particles automatically slide down along the inclined combustion section 22. As they slide, the particles gradually move away from the combustion area, quickly cutting off the heat source and extinguishing the flame. This process not only reduces the safety risks caused by residual flames during disassembly of the combustion mesh frame 2, but also avoids the possibility of burns to operators or fires caused by hot particles splashing out, greatly improving the safety of the disassembly process. This has significant advantages in combustion equipment that requires frequent replacement or maintenance of the combustion mesh frame 2, such as biomass burners which produce a large amount of combustion particles during combustion, and where the combustion mesh frame 2 needs regular cleaning or replacement. The inclined combustion section 22 effectively reduces operational risks, simplifies maintenance procedures, and effectively reduces safety risks during disassembly, ensuring efficient equipment operation and operator safety, thus possessing significant practical value and broad application prospects.

[0051] Preferably, the combustion tube 12 is adapted to be vertically arranged, and the feed tube 11 further includes a second tube 112, which is arranged above the first tube 111 and parallel to the combustion tube 12. The combustion tube 12 is also provided with a flow-reducing rod 121, which is adapted to extend vertically into the combustion chamber 10 and reach directly above the combustion section 22.

[0052] In this embodiment, the flow-reducing rod 121 is adapted to disperse the fuel falling from the combustion chamber 10, thereby reducing the falling speed of the fuel and preventing the flame from being extinguished due to rapid falling. At the same time, the cavity formed below the flow-reducing element can prevent the fuel from accumulating too densely, providing more sufficient combustion space for the fuel, thereby improving combustion efficiency.

[0053] Specifically, the combustion tube 12 is vertically arranged, allowing the heat generated during combustion to be efficiently transferred upwards along the axial direction of the combustion tube 12, thereby improving combustion efficiency and thermal energy utilization. Simultaneously, the vertical arrangement of the combustion tube 12 provides a smooth channel for the discharge of combustion products, ensuring the continuity and stability of the combustion process. The feed pipe 11 includes not only the inclined first pipe 111, but also a second pipe 112 positioned above the first pipe 111. The second pipe 112 is parallel to the combustion tube 12. A detachable fuel expansion chamber is also suitable for being installed on the second pipe 112, further increasing the volume of the feed pipe 11. The flow damping rod 121 is adapted to extend vertically into the combustion chamber 10 and precisely reach directly above the combustion section 22. The flow damping rod 121 can regulate the airflow and fuel flow within the combustion chamber 10, changing the fuel flow path and velocity distribution to allow for more thorough mixing and reaction of the fuel and combustion air above the combustion section 22, thereby improving combustion efficiency and reducing pollutants generated by incomplete combustion. By adjusting the position or shape of the flow-damping rod 121, the fluid resistance within the combustion tube 12 can be altered, thereby enhancing the combustion intensity. The flow-damping rod 121 can also guide the heat generated by combustion to distribute evenly along the combustion tube 12, preventing localized overheating and thus improving the overall thermal efficiency and service life of the combustion equipment. It is worth noting that the end of the flow-damping rod 121 is preferably located at the exact center of the combustion section 22 of the combustion grid 2. Furthermore, this application does not further limit the shape or position of the flow-damping rod 121.

[0054] Further, refer to Figure 5 The intake pipe 13 is also adapted to be detachably equipped with an adjustable valve 132, which is adapted to adjust the intake size of the intake pipe 13.

[0055] In this embodiment, the intake pipe 13 is also adapted to be detachably provided with an adjustable valve 132. The adjustable valve 132 can flexibly adjust the intake size of the intake pipe 13, thereby achieving precise control of the combustion process, ensuring that the fuel and combustion air are mixed and burned in the optimal ratio, thereby improving combustion efficiency and reducing fuel waste.

[0056] Specifically, the adjustable valve 132 is detachably installed and fixed to the intake pipe 13 via threaded connections, snap-fit ​​structures, flange connections, or hinge structures. For example, it can be detachably located at the first removal hole 130. This not only facilitates valve installation and replacement but also allows for quick maintenance or adjustment when needed, ensuring efficient operation of the equipment. The core function of the adjustable valve 132 is to control the intake air volume of the intake pipe 13 through its internal adjustment mechanism (such as a butterfly valve, needle valve, or sliding baffle). Operators can adjust the valve opening degree manually or automatically according to the actual needs of the combustion equipment, thereby precisely controlling the amount of combustion air entering the combustion chamber 10. This precise intake air adjustment capability is crucial for optimizing combustion efficiency, reducing pollutant emissions, and improving fuel utilization. Under different combustion conditions, the combustion equipment's demand for combustion air will vary. For example, in the initial stage of combustion, a smaller intake air volume may be needed to ensure stable fuel ignition; while in the vigorous combustion stage, a larger intake air volume is needed to support efficient combustion. The adjustable valve 132 can be adjusted in real time according to these dynamic needs, ensuring that the combustion process is always in the optimal state. This allows the combustion equipment to adapt to various fuel types and different combustion conditions, enhancing the versatility and flexibility of the equipment. Preferably, the adjustable valve 132 is detachably installed at the first disassembly hole 130. Of course, the adjustable valve 132 can also be installed at other positions on the intake pipe 13, which is not further limited here.

[0057] It is worth noting that the adjustable valve 132 can also be integrated with the combustion equipment's control system. By using sensors to provide feedback on parameters such as temperature, pressure, and oxygen concentration within the combustion chamber 10, intelligent intake regulation can be achieved. For example, when the sensor detects insufficient oxygen concentration in the combustion chamber 10, the valve will automatically increase its opening, increasing the intake volume; conversely, when the oxygen concentration is too high, the intake volume will be reduced. This intelligent control not only improves the automation level of the combustion equipment but also further optimizes combustion efficiency and safety.

[0058] Furthermore, the adjustable valve 132 is located at the first disassembly hole 130 of the intake pipe 13, and the mounting portion 21 of the combustion mesh frame 2 is adapted to abut against the inner wall of the adjustable valve 132. In this embodiment, the mounting portion 21 of the combustion mesh frame 2 is adapted to abut against the inner wall of the adjustable valve 132, which not only provides an additional support point for the combustion mesh frame 2, but also further enhances the fixing effect of the combustion mesh frame 2 inside the combustion device through the close cooperation with the adjustable valve 132.

[0059] Specifically, in addition to the connection between the first fixing hole 211 and the second fixing hole 131, the mounting part 21 abuts against the adjustable valve 132, forming an additional support point for the combustion mesh frame 2. This multi-point support structure is similar to the stability principle of a triangle, which can effectively disperse the force borne by the combustion mesh frame 2 and further improve its stability within the combustion chamber 10. During combustion, the combustion mesh frame 2 is subjected to multiple forces from high temperature, fuel impact, and airflow, causing the material of the combustion mesh frame 2 to undergo a certain degree of thermal expansion or deformation. By having the mounting part 21 abut against the inner wall of the adjustable valve 132, the combustion mesh frame 2 can maintain a more stable position under these complex operating conditions, effectively preventing the combustion mesh frame 2 from sinking or tilting in a high-temperature environment, reducing the risk of displacement due to vibration or impact, ensuring that the combustion part 22 is always in the optimal position, and maintaining the efficient operation of the combustion process. It is worth noting that the abutment between the mounting part 21 of the combustion mesh frame 2 and the inner wall of the adjustable valve 132 is one method of fixing the combustion mesh frame 2; it can also be fixed or abutted by other methods.

[0060] Further, refer to Figure 4 and Figure 5 It also includes an ash storage pipe 14, which is positioned below the air inlet pipe 13. The bottom of the air inlet pipe 13 is provided with several collection holes 133 that communicate with the ash storage pipe 14. The collection holes 133 are located below the combustion section 22 of the combustion grid frame 2.

[0061] In this embodiment, the ash storage pipe 14 is positioned below the air inlet pipe 13, forming a vertically corresponding spatial layout with the air inlet pipe 13. This provides a dedicated collection area for the ash and residue generated during combustion, facilitating centralized ash treatment and equipment cleaning and maintenance.

[0062] Specifically, the bottom of the air inlet pipe 13 is provided with several collection holes 133 that connect to the ash storage pipe 14. These collection holes 133 are located below the combustion section 22 of the combustion frame 2. During combustion, the ash and residue produced after fuel combustion will fall naturally and enter the ash storage pipe 14 through these collection holes 133. The collection holes 133 not only facilitate the smooth discharge of ash, but also optimize the airflow distribution in the combustion chamber 10 through their distribution and size, avoiding the adverse effects of ash accumulation on the combustion process. Moreover, the relative arrangement of the ash storage pipe 14 and the air inlet pipe 13, as well as the correspondence between the collection holes 133 and the combustion section 22 of the combustion frame 2, makes the structure of the entire combustion equipment more compact and reasonable. This not only improves the space utilization of the equipment, but also enhances the overall performance and operational stability of the combustion equipment through the effective collection and discharge of ash.

[0063] Preferably, it also includes an ash collection box 142, and the ash storage pipe 14 is also provided with a second disassembly hole 141. The ash collection box 142 can be detachably installed in the ash storage pipe 14 through the second disassembly hole 141 and is located below the collection hole 133.

[0064] In this embodiment, the ash storage pipe 14 is provided with a second disassembly hole 141, and the ash collection box 142 is detachably installed in the ash storage pipe 14 through the second disassembly hole 141. This not only improves the efficiency of ash cleaning, but also significantly improves the safety and service life of the combustion equipment by centrally collecting and safely handling ash.

[0065] Specifically, the internal space of the ash collection box 142 is used to collect ash that slides down from the combustion section 22 of the combustion mesh frame 2, preventing ash from accumulating in the ash storage pipe 14, thereby keeping the inside of the equipment clean and unobstructed. This allows the ash collection box 142 to be easily inserted and removed, facilitating regular ash cleaning by operators. The second disassembly hole 141 and the first disassembly hole 130 are located on the same side of the pipe body 1, meaning that the ash collection box 142, the adjustable valve 132, and the combustion mesh frame 2 are operated in the same direction. This allows operators to simultaneously operate the ash collection box 142, the adjustable valve 132, and the combustion mesh frame 2 from the same side, eliminating the need for frequent movement around the equipment and greatly improving maintenance efficiency and operational convenience. When it is necessary to clean the ash, the operator can first open the second disassembly hole 141 and take out the ash collection box 142 for cleaning; when it is necessary to adjust the adjustable valve 132, the adjustable valve 132 can be operated at the first disassembly hole 130 at the same time without switching the operating position; when it is necessary to adjust or maintain the combustion mesh 2, the combustion mesh 2 can be operated through the first disassembly hole 130 at the same time without switching the operating position.

[0066] Furthermore, the top of the combustion tube 12 is also provided with a transparent tube 15, and the bottom of the tube body 1 is also provided with a movable support frame 16, which is suitable for driving the tube body 1 to move arbitrarily.

[0067] In this embodiment, the transparent tube 15 allows the operator to visually observe the flame shape, combustion state, and fuel combustion within the combustion tube 12; the movable support frame 16 allows the entire combustion device to be easily moved between different positions.

[0068] Specifically, the top of the combustion tube 12 is also equipped with a transparent tube 15. The transparent tube 15 is made of a high-temperature resistant and highly transparent material, such as borosilicate glass or transparent ceramic. This not only provides a direct observation window for the combustion process, but also forms a clearly visible flame column during combustion, providing excellent visual effects and enhancing the aesthetics and watchability of the equipment. The flame column formed inside the transparent tube 15 exhibits a dynamic flame shape during combustion, providing users with a visual experience. It is especially suitable for occasions where the combustion effect needs to be demonstrated, such as educational demonstrations, exhibitions, or home fireplaces.

[0069] The bottom of the tube body 1 is also equipped with a movable support frame 16. The movable support frame 16 is made of sturdy and durable materials and is equipped with a universal wheel or slide rail, which allows the entire combustion equipment to be moved freely between different positions according to actual needs, greatly improving the flexibility and applicability of the equipment. Whether it is necessary to move the equipment to a designated combustion area or switch between different occasions, the movable support frame 16 can provide convenient movement support, reducing the difficulty of transporting the equipment and labor costs.

[0070] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
