DETAILED DESCRIPTION

[0031] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0032] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "linkage" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] As shown in Figure 1 and 4 The sound attenuation energy-saving method and device of the fierce fire stove provided by the present application comprises a cover body 1 arranged above the stove core 13, which is composed of a converging cover 2 at the upper part and a connecting cover 3 at the lower part by welding or integrally forming, and the converging cover 2 is in the shape of a gradually expanding cone or arc, which is used for converging the flame and improving the heating area and thermal efficiency of the bottom of the pot.

[0034] As shown in Figures 1-2 The bottom inner side of the connecting cover 3 is detachably provided with a sound attenuation member 4 by buckle, screw or clay, which comprises a ring-shaped supporting ring 8, and a ventilation component 9 is arranged on the supporting ring 8, and high-temperature-resistant granular sound attenuation aggregate 11 is laid on the ventilation component 9, the particle size of the sound attenuation aggregate is 3mm-8mm, and it is made of high-aluminum material. Because the temperature of the sound attenuation aggregate after high-temperature burning is higher than the temperature of the original stove, it can save gas.

[0035] As shown in Figure 7 As the first embodiment of the present application, the ventilation component 9 is a plurality of high-temperature-resistant ventilation strips arranged along the circumference of the supporting ring 8 at intervals, ventilation gaps are formed between adjacent ventilation strips, the ventilation strips are arranged in the shape of a long strip, and a plurality of ventilation strips at the center are fixed with a blocking disc 10 at the bottom, which is arranged in the shape of a cone, and the blocking disc 10 is close to the center of the stove core 13, and uniform ventilation gaps are left between adjacent ventilation strips 9, and the sound attenuation aggregate 11 is laid in the area surrounded by the ventilation strips 9 during installation and use.

[0036] As shown in Figure 8 As the second embodiment of the present application, the ventilation component 9 is a hole plate, the central area of the hole plate is blocked, and the hole plate is clamped on the supporting ring 8.

[0037] As shown in Figure 9 As the third embodiment of the present application, the ventilation component 9 is a disc-shaped plate with a downward recess at the center, a plurality of through holes are arranged on the outer periphery of the disc-shaped plate, and the top of the disc-shaped plate is clamped on the supporting ring 8.

[0038] As shown in Figure 2As shown, two holes are opened on the bottom outer wall of the connecting cover 3, which are the gas injection hole 5 and the ignition needle hole 6 respectively. On the inner wall of the connecting cover 3, two high-temperature-resistant stainless steel plates are welded as heat insulation protection plates 7 respectively.

[0039] As shown, Figures 3-4 When installed, a high-temperature-resistant ceramic fiber sealing gasket 12 is first placed on the supporting surface of the furnace core 13 of the fierce fire stove. A through hole is opened on the supporting surface of the furnace head at the side position of the furnace head, which is used for pipeline leading out. Then, the bottom of the connecting cover 3 is aligned and pressed on the sealing gasket 12 to realize sealed connection and prevent the flame and heat from leaking from the bottom.

[0040] As shown, Figure 2 and 6 Next, the ignition needle 14 is led out from below the furnace head through the through hole and inserted into the ignition needle hole 6, with the ignition tip located on the inner side of the heat insulation protection plate 7. Similarly, the outlet end of the fire gas nozzle 15 with the top bent into an L shape is inserted into the gas injection hole 5, and the bottom end of the gas inlet pipeline is also led out to the furnace body below through the through hole. The pipelines of the ignition needle 14 and the fire gas nozzle 15 are connected to the control system and the gas pipeline respectively, and the main body part of the fire gas nozzle 15 is surrounded by another heat insulation protection plate 7.

[0041] When working, the fan (not shown in the figure) sprays the mixed gas of air and gas upward from the nozzle of the furnace core 13. The mixed gas flow first vertically impacts the center of the blocking disc 10 and is forced to change direction, spreading radially around. The diffused gas flow is then divided into multiple small streams through multiple narrow ventilation gaps. These streams then flow into the zigzag and porous channels formed by the sound-absorbing aggregate 11, generating a large amount of turbulence and friction. A large amount of sound energy is consumed in this process, thereby achieving significant noise reduction. After the sound-absorbing treatment, the gas flow meets the ignition flame sprayed from the fire gas nozzle 15 and burns stably and centrally under the constraint of the converging cover 2, and the heat energy is efficiently utilized. During the whole process, the heat insulation protection plate 7 effectively blocks the direct roasting of the main flame to the ignition needle 14 and the fire gas nozzle 15, ensuring the safety and stability of long-term use.

[0042] The above describes the present application and its embodiments, which are not limited. The embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the present application, without creative design, similar structure and embodiments of the technical solution can be designed and belong to the protection scope of the present application.
