Description

Technical Field

[0001] This utility model belongs to the technical field of fuel devices, specifically relating to a fuel furnace. Background Technology

[0002] Pellet fuel, as a block-shaped environmentally friendly new energy source, has advantages such as high calorific value, high purity, and environmental friendliness, and can be used as a future environmentally friendly fuel. However, most pellet fuel furnaces have the following drawbacks when burning pellet fuel: backfire is prone to occur during combustion, and the flames inside the furnace may spray towards the feed structure, causing the pellet fuel inside the feed structure to burn, which can easily burn the feed structure and its pellet fuel.

[0003] To address the aforementioned issues, existing pellet fuel furnaces utilize a motor-driven long spiral blade to deliver pellet fuel to the furnace for combustion. While the long spiral blade prevents backfire, it requires a length of at least 40-50cm, necessitating a high-power motor. This high-power motor requires AC power, making it inconvenient for outdoor use. Furthermore, the long spiral blade is prone to jamming, affecting the furnace's operation. Utility Model Content

[0038] Combination Figures 1 to 3 As shown, this utility model provides a fuel furnace, which includes: a combustion chamber 10; a feeding section 20 connected to the combustion chamber 10; a feeding section 30 having an inlet 310 and an outlet 320, the outlet 320 being connected to the feeding section 20; the feeding section 30 and the feeding section 20 being arranged at an angle; a spiral blade 40 disposed within the feeding section 30; and a feeding motor 60 rotatably connected to the spiral blade 40.

[0039] Specifically, when the feeding motor 60 is energized, it drives the spiral blades to rotate within the feeding section 30, thereby feeding the fuel from the inlet 310 to the outlet 320 and into the discharge section 20, where it finally enters the combustion chamber 10 for combustion. This application employs the above-described structure for feeding. The feeding section 30 and the combustion chamber 10 are separated by the discharge section 20. By changing the power of the feeding motor 60, the feeding speed is rationally controlled. Even if the combustion chamber 10 experiences backfire via the discharge section 20, the flames cannot contact the fuel in the feeding section 30, preventing the fuel from being ignited and solving the backfire problem.

[0040] In addition, since the tempering problem has been solved, the length of the spiral blade 40 can be shortened, thereby solving the material jamming problem caused by the excessive length of the spiral blade 40. Moreover, since the length of the spiral blade 40 is shortened, the power requirement of the feeding motor 60 is reduced accordingly, so that a low-power feeding motor 60, such as a DC driven motor, can be used, which is convenient for outdoor use.

[0041] Compared with the prior art, this application abandons the existing method of using only long spiral blades 40 for feeding to prevent backfire. Instead, it innovatively uses a combination of feeding section 20 and feeding section 30 for feeding. While maintaining sufficient distance to prevent backfire, the length of the spiral blades 40 in the feeding section 30 can be shortened as much as possible by setting the feeding section 30 and the feeding section 20 at an angle, thereby reducing the lateral space occupied by the fuel furnace and avoiding material jamming.

[0042] In this embodiment, the combustion chamber 10 and the feeding section 20 are arranged at a first angle; the feeding section 30 and the feeding section 20 are arranged at a second angle, the second angle being complementary to the first angle. The positional relationship between the combustion chamber 10, the feeding section 20, and the feeding section 30 is reasonably determined to ensure that the feeding section 30 is horizontally arranged relative to the combustion chamber 10, and to ensure that there is sufficient distance to prevent fuel backfire while ensuring normal feeding of the feeding section 30.

[0043] Furthermore, the feeding section 20 is inclined relative to the combustion chamber 10. By using the inclined feeding method, the fuel entering the feeding section 20 from the discharge port 320 can slide down the feeding section 20 into the combustion chamber 10 under the action of gravity.

[0044] Furthermore, the feeding section 30 is set horizontally so that the fuel in the feeding section 30 can be accurately fed under the rotation of the spiral blade 40, avoiding the phenomenon of fuel naturally falling into the unloading section 20 when it is set from top to bottom, or the problem of increased load on the feeding motor 60 when it is set from bottom to top.

[0045] To facilitate the installation of the feeding section 20 and the combustion chamber 10, in this embodiment, a feeding port 110 is provided on the outer side of the combustion chamber 10. The feeding section includes a feeding section side plate and a feeding section sliding plate. The feeding section side plate is disposed around the feeding section sliding plate. The lower end of the feeding section sliding plate is inserted into the feeding port. The lower end of the feeding section side plate is provided with an installation part, which is fixedly connected to the outer wall of the combustion chamber. In this embodiment, the lower end of the feeding section sliding plate 210 is inserted into the feeding port 110 to initially position the feeding section sliding plate 210 and the combustion chamber 10. Then, the installation part 221 is used to fix the feeding section side plate 220 to the outer wall of the combustion chamber 10, thereby realizing the installation of the feeding section side plate 220 and the combustion chamber 10. The operation is simple and convenient, solving the problem of difficult positioning when the feeding section 20 and the combustion chamber 10 are fixed by welding.

[0046] In this embodiment, the fuel furnace further includes an outer frame 50, which surrounds the combustion chamber 10 and forms a circulation chamber with the combustion chamber 10; the upper and lower parts of the combustion chamber 10 are provided with through holes 120; the combustion chamber 10 is provided with a combustion chamber, which is connected to the circulation chamber through the through holes 120.

[0047] When the combustion chamber 10 is working, the air in the circulation chamber flows into the combustion chamber through the lower through hole 120 to assist the combustion of fuel. At the same time, the air in the circulation chamber forms a negative pressure due to the air flow. The flue gas generated during the combustion of fuel in the combustion chamber enters the circulation chamber through the upper through hole 120 to achieve secondary recovery of flue gas. The flue gas flows back to the inner chamber with the air flow through the lower through hole 120 so that the particulate fuel can be fully burned.

[0048] Furthermore, the fuel furnace also includes a blower 70, which is mounted on the outer frame 50. The outlet of the blower 70 is connected to the circulation chamber, and the blower 70 delivers air into the circulation chamber to generate an airflow to aid combustion.

[0049] Furthermore, the upper end of the feeding section 20 is fixedly connected to the inner side of the outer frame 50. The upper and lower ends of the feeding section 20 are fixed by means of the inner side of the outer frame 50, thereby determining the position of the feeding section 20 and preventing the position of the feeding section 20 from changing.

[0050] In this embodiment, a temperature measuring hole is provided on the outside of the combustion chamber 10; the fuel furnace also includes a temperature measuring probe 80, which is inserted into the temperature measuring hole. The temperature measuring probe 80 is used to detect the combustion temperature in the combustion chamber 10 and accurately control the temperature.

[0051] In this embodiment, the fuel furnace further includes a feeding hopper 90, which has a feeding port and a discharging port. The discharging port is connected to the feeding port 310 so that the feeding hopper 90 can be used to store materials and facilitate the addition of large quantities of materials.

[0052] Furthermore, the fuel furnace can be installed and combined with other devices to transform it into a barbecue grill, combustion oven, pizza oven, etc. It should be noted that fuel devices involving fuel feeding are all within the scope of this application.

[0053] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
