Description

A gasification furnace with a tornado-like rotating flame effect Technical Field

[0001] This utility model relates to a vaporization furnace with a tornado rotating flame effect. Background Technology

[0002] A gasifier is a cooking and heating device that achieves complete combustion and reduces smoke emissions through a secondary oxygen supply method. It generally uses combustible biomass such as firewood, straw, sawdust, rice husks, and leaves as fuel. With the improvement of living standards, the function of gasifiers is no longer limited to outdoor fire starting. More often, gasifiers are used as ornamental devices. However, the flame shape of existing gasifiers is irregular and easily affected by the outside air flow, resulting in irregular flickering, which lacks ornamental value and playability.

[0003] Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a gasification furnace with a tornado rotating flame effect.

[0005] To achieve the above objectives, this utility model provides a gasification furnace with a tornado-like rotating flame effect, comprising a cylindrical outer shell and a furnace core placed within the outer shell. The furnace core includes a carbon bridge and a secondary combustion enclosure plate connected to the carbon bridge. The carbon bridge is fixedly connected to the outer shell via a carbon bridge fixing frame, and a cavity is formed between the secondary combustion enclosure plate and the outer shell. The carbon bridge has multiple ventilation holes, and the lower part of the outer shell has multiple air inlets. The multiple air outlets are inclined at the same angle in the same direction. The air inlets are connected to the air outlets through the cavity. Along the height direction of the secondary combustion enclosure plate, the multiple air outlets form at least one layer of concentric circular structures. On each layer of the concentric circular structures, the multiple air outlets are evenly distributed on a circumference, so that the upper part of the secondary combustion enclosure plate forms a unidirectional vortex tornado-like rotating flame effect.

[0006] Furthermore, viewed from top to bottom, the multiple air outlets are inclined at the same angle in the counterclockwise direction, with an angle of 3 to 10 degrees. Along the height direction of the secondary combustion enclosure, the multiple air outlets form a two-layer concentric circular structure, and the positions of the air outlets on the two layers of concentric circular structures are staggered.

[0007] Furthermore, a narrow opening is formed at the upper end of the outer shell, and the narrow opening limits the secondary combustion enclosure at the upper end.

[0008] Furthermore, a positioning groove is formed at the constricted opening, which is used for placing the flame shield so that the flame is further concentrated towards the center.

[0009] Furthermore, the carbon bridge and the secondary combustion enclosure are connected by insertion and then welding. Specifically, the carbon bridge has an insertion hole, and the lower end of the secondary combustion enclosure has an insertion part, the insertion hole being used to receive the insertion part.

[0010] Furthermore, the carbon bridge fixing frame is welded to the outer shell, while the carbon bridge fixing frame and the carbon bridge are bolted together.

[0011] Furthermore, the outer casing is divided into two parts: a main casing and a base. The air inlet is formed on the main casing, and the base is detachably connected to the lower part of the main casing.

[0012] Furthermore, the lower part of the base is fixed with support feet.

[0013] The advantages of this utility model over the prior art are as follows: The gasification furnace has an overall cylindrical design and an inclined air outlet is designed on the upper part of the secondary combustion enclosure. On the basis of achieving full combustion with secondary oxygen supply, it achieves a vortex tornado rotating flame effect, which is aesthetically pleasing and meets the needs of various scenarios. The product design is beautiful and elegant, easy and quick to assemble, has high thermal efficiency, and produces less smoke and dust, which helps to improve the customer's product experience.

[0021] As shown in Figures 1-3, a gasification furnace with a tornado-like rotating flame effect according to an embodiment of this utility model includes a cylindrical outer shell 2 and a furnace core 4 placed inside the outer shell 2. The furnace core 4 includes a carbon bridge 41. The secondary combustion enclosure 42 is connected to the carbon bridge 41. The carbon bridge 41 is fixedly connected to the outer shell 2 through the carbon bridge fixing bracket 3. A cavity a is formed between the secondary combustion enclosure 42 and the outer shell 2. Multiple vent holes 411 are machined on the carbon bridge 41. Multiple air inlets 221 are machined on the lower part of the outer shell 2. Multiple air outlets 421 are machined on the upper edge of the secondary combustion enclosure 42. The multiple air outlets 421 are inclined at the same angle in the same direction. The air inlets 221 are connected to the air outlets 421 through the cavity a. Along the height direction of the secondary combustion enclosure 42, the multiple air outlets 421 form at least one layer of concentric circular structure. On each layer of concentric circular structure, the multiple air outlets 421 are evenly distributed on a circumference, so that the upper part of the secondary combustion enclosure 42 forms a unidirectional vortex tornado rotating flame effect.

[0022] As shown in Figures 2 and 4, the secondary combustion enclosure (42) includes an inner wall (422) and an outer wall (423). An exhaust port (421) is disposed on the secondary combustion enclosure (42), and the exhaust port (421) can be further divided into a left end (4211) and a right end (4212). In this embodiment, the left end (4211) of the exhaust port is recessed towards the outer wall (423) and protrudes from the outer wall (423), while the right end (4212) of the exhaust port is recessed towards the inner wall (422) and protrudes from the inner wall (422). Two rows of vent holes (421) are arranged on the secondary combustion enclosure (42), and these vent holes (421) are arranged in an inclined manner. In actual application, the flame is ejected through the vent holes (421) to form a flame network in the Northern Hemisphere counterclockwise vortex shape (as shown by the circular trajectory in Figure 4) (see Figures 5 and 6).

[0023] In other embodiments, the vent (421) on the secondary combustion enclosure (42) is configured such that the left end (4211) of the vent is recessed towards the inner wall (422) of the secondary combustion enclosure and protrudes from the inner wall (422), and the right end (4212) of the vent is recessed towards the outer wall (423) of the secondary combustion enclosure and protrudes from the outer wall (423). This arrangement causes the flame to be ejected from the vent (421) in use, forming a clockwise vortex in the Southern Hemisphere (not shown in the figure).

[0024] As shown in Figure 4, from the top to the bottom of the secondary combustion enclosure (42), i.e., looking down, multiple air vents 421 are inclined at the same angle in a counterclockwise direction, with an angle of 3 to 10 degrees. Along the height of the secondary combustion enclosure (42), the multiple air vents 421 form two concentric circular structures. The positions of the air vents 421 on the two concentric circular structures are staggered. The number of air vents 421 on the two concentric circular structures can be the same or different. A constriction 222 is formed at the upper end of the outer shell 2, which limits the secondary combustion enclosure 42 at the upper end. A positioning groove 223 is also formed at the constriction 222, which is used for the flame cover 5. The placement allows the flame to converge further towards the center; the carbon bridge 41 and the secondary combustion enclosure 42 are connected by insertion and then welding. Specifically, the carbon bridge 41 has insertion holes, and the lower end of the secondary combustion enclosure 42 has insertion parts. The insertion holes are used to receive the insertion parts; the carbon bridge fixing frame 3 and the outer shell 2 are connected by welding, and the carbon bridge fixing frame 3 and the carbon bridge 41 are connected by bolts; the outer shell 2 is divided into two parts: the main shell 22 and the base 21. The air inlet 221 is formed on the main shell 22, and the base 21 is detachably connected to the lower part of the main shell 22. The ash generated by combustion leaks down through the vent 411 and is deposited in the base 21. The ash can be easily discharged by inverting; the lower part of the base 21 is fixed with a support foot 1.

[0025] The gasifier features a cylindrical design with sloping vents on the upper part of the secondary combustion enclosure. This design achieves a vortex-like rotating flame effect while ensuring sufficient combustion through secondary oxygen supply. It is visually appealing and meets the needs of various applications. The product boasts an attractive design, is easy and quick to assemble, has high thermal efficiency, and produces minimal smoke and dust, thus enhancing the customer's product experience.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
