Description

Technical Field

[0001] This utility model relates to the field of burners, and more specifically, to a burner air-fuel ratio adjustment mechanism. Background Technology

[0002] A burner is a general term for a device that sprays out fuel and air in a certain way to mix and burn. Burners are classified into several types according to their application fields, such as industrial burners, combustion engines, civil burners, and special burners. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium.

[0003] A search revealed that Chinese Patent Publication No. CN222417430U discloses "a proportionate adjustable burner, which includes a burner body and a flame pipe disposed on one side of the burner body. A connecting pipe communicating with the interior of the burner body is installed on one side of the burner body, and a gas pipe is installed on one side of the connecting pipe. A sealing plate is installed inside the connecting pipe, and multiple annularly arranged strip-shaped openings are formed on the sealing plate. Multiple sets of adjustment mechanisms that cooperate with the multiple strip-shaped openings are installed inside the connecting pipe, which can adjust the size of the strip-shaped openings. The adjustment mechanism includes a baffle located inside the connecting pipe and a working box installed outside the connecting pipe. This utility model can adjust the gas flow rate by changing the size of the gas inlet of the strip-shaped openings during use, and thus adjust the proportion of gas. This allows for effective control of the flame size during use, making it more convenient for users." However, it still has the following drawbacks:

[0004] The regulating mechanism of this proportional burner uses a multi-gear rack and pinion transmission system to regulate the flow of gas. During long-term operation, the gears and racks may become stuck or the transmission may become inaccurate due to thermal deformation, carbon buildup, or wear, affecting the reliability of the regulation.

[0005] Therefore, a burner air-gas ratio adjustment mechanism is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that existing regulating mechanisms using multi-gear rack and pinion transmission systems to regulate gas flow may experience jamming or inaccurate transmission due to thermal deformation, carbon buildup, or wear during long-term operation, thus affecting the reliability of regulation. This invention provides a burner air-gas ratio regulating mechanism to solve the aforementioned problems.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a burner air-fuel ratio adjustment mechanism, including a burner body, an adjustment component for adjusting air and gas flow is bolted to one side of the burner body, and a drive component for driving the adjustment mechanism to adjust the air flow is provided on one side of the adjustment mechanism.

[0009] The adjustment assembly includes an air inlet pipe and an air intake pipe bolted to one side of the burner body. A first rotating rod is rotatably connected to the top of the air inlet pipe, and a second rotating rod is rotatably connected to the top of the air intake pipe. A gas valve plate is fixedly connected to the first rotating rod, and an air damper is fixedly connected to the second rotating rod.

[0010] As a preferred technical solution of this utility model, the driving component includes a first geared disc sleeved on the first rotating rod, a second geared disc sleeved on the second rotating rod, the first geared disc and the second geared disc meshing with each other, and a handle fixedly connected to the top of the first rotating rod.

[0011] As a preferred technical solution of this utility model, there are two sets of gas valve plates and damper baffles, which are symmetrically installed on both sides of the first rotating rod and the second rotating rod, respectively.

[0012] As a preferred technical solution of this utility model, an arc-shaped guard plate is fixedly provided at the top and bottom of the first gear plate, the arc-shaped guard plate is fixedly connected to the first rotating rod, and the arc-shaped guard plate is located on one side of the handle.

[0013] As a preferred embodiment of this invention, the first gear plate is located on one side of the arc-shaped guard plate, and the air intake pipe is located on one side of the arc-shaped guard plate.

[0014] As a preferred technical solution of this utility model, a flame tube is bolted to the output end of the burner body, and an igniter is fixedly installed on the top of the burner body, with the igniter extending into the interior of the burner body.

[0015] As a preferred embodiment of this invention, the air inlet pipe and the air intake pipe are connected inside the burner body, and the flame jet pipe is located on one side of the air inlet pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The intake of gas and air can be adjusted by the set adjustment components. Specifically, rotating the first rotating rod drives the gas valve plate to rotate, thereby changing the flow area of ​​the air intake pipe and realizing precise adjustment of the gas flow. The second rotating rod drives the damper to adjust the opening of the air intake pipe, thereby controlling the intake of air and ensuring that the ratio of gas to air is always in the optimal combustion state.

[0018] 2. Through the set drive component, the user can adjust the ratio of gas flow and air intake by turning a handle. Specifically, the user manually turns the handle, which drives the first rotating rod to rotate. Since the first and second gears mesh with each other, the rotation of the first rotating rod will synchronously drive the rotation of the second rotating rod. The rotation of the gas valve plate and the damper can be controlled simultaneously by a single handle. Since the number of teeth on the second gear plate is slightly more than that on the first gear plate, there is a certain proportional relationship between the rotation angles of the gas valve plate and the damper, thereby realizing the ratio adjustment of gas flow and air intake.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figure 1 As shown, this embodiment proposes a burner air-gas ratio adjustment mechanism, including a burner body 1, an adjustment component 2 for adjusting air and gas flow is bolted to one side of the burner body 1, and a drive component 3 for driving the adjustment mechanism to adjust the air flow is provided on one side of the adjustment mechanism.

[0030] like Figure 2 and Figure 4 As shown, the regulating assembly 2 includes an intake pipe 201 and an air intake pipe 202 bolted to one side of the burner body 1. A first rotating rod 203 is rotatably connected to the top of the intake pipe 201, and a second rotating rod 204 is rotatably connected to the top of the air intake pipe 202. A gas valve plate 205 is fixedly connected to the first rotating rod 203, and an air damper 206 is fixedly connected to the second rotating rod 204. In use, rotating the first rotating rod 203 causes the gas valve plate 205 to rotate, thereby changing the flow area of ​​the intake pipe 201 and achieving precise regulation of the gas flow. The second rotating rod 204 drives the air damper 206 to adjust the opening of the air intake pipe 202, thereby controlling the amount of air entering and ensuring that the ratio of gas to air is always in the optimal combustion state. This not only improves combustion efficiency and reduces energy waste, but also effectively reduces the emission of harmful gases caused by improper mixing.

[0031] like Figure 4 and Figure 5 As shown, the drive assembly 3 includes a first gear 301 sleeved on the first rotating rod 203, a second gear 302 sleeved on the second rotating rod 204, the first gear 301 and the second gear 302 meshing with each other, and a handle 303 fixedly connected to the top of the first rotating rod 203. In use, the user manually turns handle 303, which drives the first rotating rod 203 to rotate. Since the first gear 301 and the second gear 302 mesh with each other, the rotation of the first rotating rod 203 will synchronously drive the second rotating rod 204 to rotate. The rotation of the gas valve plate 205 and the damper 206 can be controlled simultaneously through one handle 303. Since the number of teeth of the second gear 302 is slightly more than that of the first gear 301, there is a certain proportional relationship between the rotation angles of the gas valve plate 205 and the damper 206. This achieves proportional adjustment of the gas flow and the amount of air entering, further ensuring that the gas and air are always in the optimal combustion ratio, avoiding problems such as incomplete combustion or over-combustion caused by imbalance in the ratio.

[0032] like Figure 4 As shown, there are two sets of gas valve plates 205 and air damper plates 206, which are symmetrically installed on both sides of the first rotating rod 203 and the second rotating rod 204, respectively. When the first rotating rod 203 is rotated, the gas valve plate 205 will rotate within the air intake pipe 201, thereby adjusting the gas flow rate. When the second rotating rod 204 is rotated, the air damper plate 206 will rotate within the air intake pipe 202, thereby adjusting the air flow rate, thus improving the stability and uniformity of combustion.

[0033] like Figure 3 As shown, arc-shaped guard plates 4 are fixedly installed on the top and bottom of the first gear disc 301. The arc-shaped guard plates 4 are fixedly connected to the first rotating rod 203 and are located on one side of the handle 303. During use, the meshing point of the first gear disc 301 and the second gear disc 302 is always located inside the arc-shaped guard plate 4, ensuring the smoothness and reliability of the rotation of the first gear disc 301 and the second gear disc 302.

[0034] like Figure 3 and Figure 4 As shown, the first gear disc 301 is located on one side of the arc-shaped guard plate 4, and the air intake pipe 201 is also located on one side of the arc-shaped guard plate 4. The arc-shaped guard plate 4 provides a certain degree of protection for the first gear disc 301, preventing external dust and other debris from entering the meshing part of the first gear disc 301 and the second gear disc 302, thus extending the service life of the first gear disc 301 and the second gear disc 302 to a certain extent.

[0035] like Figure 2 As shown, a flame tube 5 is bolted to the output end of the burner body 1, and an igniter 6 is fixedly installed on the top of the burner body 1, extending into the interior of the burner body 1. Gas and air enter the burner body 1 in a suitable ratio for thorough mixing. The igniter 6 generates an electric spark, igniting the gas mixture. The high-temperature flame and large amount of heat energy generated by combustion are ejected outward through the flame tube 5, which is model DZ200-3A.

[0036] like Figure 2 As shown, the intake pipe 201 and the air intake pipe 202 are connected to the interior of the burner body 1, and the flame nozzle 5 is located on one side of the intake pipe 201. The intake pipe 201 is responsible for introducing the combustion gas into the interior of the burner body 1, while the air intake pipe 202 introduces air. The combustion gas and air are mixed. At this time, the igniter 6 generates an electric spark to ignite the mixture, and the high-temperature flame is ejected outward through the flame nozzle 5.

[0037] Specifically, in use, the air-fuel ratio adjustment mechanism of this burner works as follows: rotating the first rotating rod 203 causes the gas valve plate 205 to rotate, thereby changing the flow area of ​​the air intake pipe 201 and achieving precise adjustment of the gas flow rate. The second rotating rod 204 drives the damper 206 to adjust the opening of the air intake pipe 202, thereby controlling the amount of air entering. When the user manually rotates the handle 303, the handle 303 drives the first rotating rod 203 to rotate. Since the first gear plate 301 and the second gear plate 302 mesh with each other, the rotation of the first rotating rod 203 will be synchronized. The second rotating rod 204 is driven to rotate, and the rotation of the gas valve plate 205 and the damper plate 206 can be controlled simultaneously through a handle 303. Since the number of teeth of the second gear plate 302 is slightly more than that of the first gear plate 301, there is a certain proportional relationship between the rotation angles of the gas valve plate 205 and the damper plate 206. This allows for the proportional adjustment of the gas flow and air intake, further ensuring that the gas and air are always in the optimal combustion ratio, and avoiding problems such as incomplete combustion or over-combustion caused by imbalance in the ratio.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
