Description

Technical Field

[0001] This utility model belongs to the technical field of anti-clogging burners, specifically relating to an anti-clogging burner for high-concentration dust gas fuel. Background Technology

[0002] For example, blast furnace gas, biomass gasification gas, and coal chemical synthesis gas are collectively referred to as high-concentration dust gaseous fuels. Because these gaseous fuels contain a large amount of solid dust, ordinary burners are prone to problems such as nozzle clogging, ash accumulation in the airflow channel, and unstable combustion, which can even lead to equipment shutdown. High-concentration dust gaseous fuel anti-clogging burners are combustion devices specifically designed for the characteristics of these fuels. The core objective is to solve the pain point of dust clogging through structural optimization and functional design while ensuring efficient combustion. They are suitable for industrial heating, power generation, waste-to-energy conversion, and other scenarios.

[0003] Currently, when high-concentration dust gaseous fuels are burned, they need to be mixed with air. At present, most of these mixtures are achieved through a mixing chamber inside the burner. However, the existing mixing chambers are not very effective, resulting in the combustibles in the high-concentration dust gaseous fuels not being able to fully contact the air. This reduces the combustion efficiency of the combustibles and also reduces the utilization rate of the fuel. This leads to waste due to the discharge of incompletely burned flue gas. Moreover, the incompletely burned flue gas can easily cause blockage of the burner, which is not conducive to long-term use.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a high-concentration dust gas fuel anti-clogging burner.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0030] like Figures 1 to 7 As shown, a high-concentration dust gas fuel anti-clogging burner according to one embodiment of the present invention includes: a burner mixing chamber body 1, a mixing and agitating mechanism 2, and a synchronization mechanism 3. The mixing and agitating mechanism 2 is disposed within the burner mixing chamber body 1 and includes a mixing component 21, a reciprocating rotation component 22, and a rotation component 23. The mixing component 21 is disposed within the burner mixing chamber body 1, the reciprocating rotation component 22 is disposed within the burner mixing chamber body 1, and the rotation component 23 is fixedly installed within the reciprocating rotation component 22. The synchronization mechanism 3 is fixedly installed within the burner mixing chamber body 1.

[0031] The method of using this high-concentration dust gas fuel anti-clogging burner is as follows: Air and dust gas fuel are synchronously injected into the burner mixing chamber body 1, and the mixing component 21 is started. The mixing component 21 mixes the air and gas fuel. At the same time, the operation of the mixing component 21 can drive the synchronous rotation of the rotating repetitive component 22 through the synchronization mechanism 3. The rotation of the mixing component 21 will be in the opposite direction to the rotation of the rotating repetitive component 22. Meanwhile, the rotating repetitive component 22 cleans the inner wall of the burner mixing chamber body 1, reducing the settling of combustibles in the gas fuel. The self-rotating component 23 can improve the stirring effect of the mixing component 21, thereby improving the mixing effect of air and gas fuel.

[0032] like Figures 1 to 5 As shown, the mixing assembly 21 includes: a mixing positioning shaft 211, a mixing positioning frame 212, a mixing motor 213, multiple mixing support shafts 214, and multiple mixing frames 215. The mixing positioning shaft 211 is located inside the burner mixing chamber body 1 and can drive the rotation of the mixing support shafts 214. The mixing motor 213, model YS7124, provides corresponding support for the rotation of the mixing support shafts 214 and also provides a suitable position for the installation of the mixing support shafts 214, reducing the probability of the mixing support shafts 214 detaching. The mixing positioning frame 212 is fixedly installed inside the burner mixing chamber body 1, which can fix the installation of the mixing motor 213, improving the stability of the mixing motor 213, reducing the probability of the mixing motor 213 detaching, and reducing the shaking of the mixing motor 213. A mixing motor 213 is fixedly installed on the side of the mixing positioning frame 212 away from the mixing positioning shaft 211. The mixing motor 213 can drive the rotation of the mixing positioning shaft 211, providing the corresponding power for the rotation of the mixing positioning shaft 211. Multiple mixing support shafts 214 are rotatably installed on the outside of the mixing positioning shaft 211 and are evenly distributed. The mixing support shafts 214 can mix the air and gaseous fuel in the burner mixing chamber body 1, improving the uniformity of mixing and improving the utilization rate of gaseous fuel. Multiple mixing frames 215 are fixedly installed on the outside of the mixing support shafts 214 and are evenly distributed. The mixing frames 215 can improve the mixing effect of the mixing support shafts 214.

[0033] like Figures 1 to 4 As shown, a hybrid shaft seat 216 is installed between the hybrid support shaft 214 and the hybrid positioning shaft 211, which improves the stability of the hybrid support shaft 214, reduces the probability of the hybrid support shaft 214 detaching, and makes the rotation of the hybrid support shaft 214 more stable. The hybrid motor 213 is installed through the hybrid positioning frame 212, which facilitates the installation of the hybrid motor 213 and the hybrid positioning shaft 211 and provides convenience for the rotation of the hybrid positioning shaft 211.

[0034] like Figures 1 to 5As shown, the mixing motor 213 is fixedly installed with the mixing positioning shaft 211, which facilitates the driving of the mixing positioning shaft 211 by the mixing motor 213 and provides corresponding power for the rotation of the mixing positioning shaft 211. The mixing frame 215 is fixedly installed with a mixing filter screen 217, which can improve the mixing effect of air and gaseous fuel.

[0035] like Figures 1 to 6 As shown, the reciprocating rotation assembly 22 includes: multiple reciprocating blades 221, a reciprocating circular plate 222, a reciprocating gear ring 223, and multiple reciprocating connecting rods 224. The multiple reciprocating blades 221 are disposed within the burner mixing chamber body 1 and are evenly distributed. The reciprocating blades 221 can scrape the inner wall of the burner mixing chamber body 1. When some combustible material in the gaseous fuel settles, the combustible material can be transported to the top of the burner mixing chamber body 1 and fall naturally, thereby improving the mixing degree of air and gaseous fuel. The reciprocating circular plate 222 is rotatably mounted on the mixing positioning shaft 211. The reciprocating circular plate 222 can provide a corresponding position for the installation of the reciprocating gear ring 223, effectively fixing the position of the reciprocating gear ring 223, reducing the probability of positional displacement of the reciprocating gear ring 223, and improving the stability of the reciprocating gear ring 223. A repetitive gear ring 223 is fixedly installed on one side of the repetitive circular plate 222. The repetitive gear ring 223 can connect the repetitive connecting rod 224 and the repetitive blade 221. When the repetitive gear ring 223 rotates, it can drive the repetitive blade 221, causing the repetitive blade 221 to rotate and drive the mixing positioning shaft 211 in opposite directions. Multiple repetitive connecting rods 224 are fixedly installed between the repetitive blade 221 and the repetitive gear ring 223, connecting the repetitive blade 221 and the repetitive gear ring 223, which can improve the stability of the repetitive blade 221.

[0036] like Figures 1 to 3 As shown, the hybrid positioning shaft 211 is set through the repetitive circular plate 222, and a repetitive bearing 225 is installed between the hybrid positioning shaft 211 and the repetitive circular plate 222, which improves the smoothness of the rotation of the repetitive circular plate 222 and reduces the probability of the repetitive circular plate 222 detaching.

[0037] like Figures 1 to 2 As shown, the rotating assembly 23 includes multiple rotating bevel gear rings 231 and multiple rotating bevel gears 232. The multiple rotating bevel gear rings 231 are fixedly installed within multiple reciprocating blades 221 and are evenly distributed. The relative movement between the rotating bevel gear rings 231 and the rotating bevel gears 232 allows the mixing support shaft 214 to rotate, thereby improving the agitation effect on the air and gaseous fuel. The multiple rotating bevel gears 232 are all fixedly installed at the end of the mixing support shaft 214 away from the mixing positioning shaft 211 and are matched with the rotating bevel gear rings 231.

[0038] like Figures 1 to 2As shown, the synchronization mechanism 3 includes: a synchronization fixing block 31, a transmission assembly 32, and a supporting synchronization inner wheel 33. The synchronization fixing block 31 is fixedly installed inside the burner mixing chamber body 1, and can fix the transmission assembly 32, thereby improving the stability of the transmission assembly 32. The transmission assembly 32 is rotatably mounted on the side of the synchronization fixing block 31 near the reciprocating gear ring 223. The supporting synchronization inner wheel 33 is fixedly installed on the mixing positioning shaft 211, and can drive the rotation of the transmission assembly 32.

[0039] like Figures 1 to 5 As shown, the transmission assembly 32 includes a support transmission rod 321, a support bearing 322, and a support synchronizing gear 323. The support transmission rod 321 is rotatably mounted on one side of the synchronizing fixing block 31. The support transmission rod 321 can position the support synchronizing gear 323, reducing the probability of the support synchronizing gear 323 disengaging and the possibility of the support synchronizing gear 323 tilting. The support bearing 322 is installed between the support transmission rod 321 and the synchronizing fixing block 31. The support bearing 322 can reduce the friction between the support transmission rod 321 and the synchronizing fixing block 31, improving the service life of both the support transmission rod 321 and the support bearing 322. The support synchronizing gear 323 is fixedly installed on the side of the support transmission rod 321 near the reciprocating gear ring 223, serving a transmission function, enabling the support synchronizing inner wheel 33 to drive and rotate the reciprocating gear ring 223.

[0040] like Figures 1 to 6 As shown, both the reciprocating gear ring 223 and the supporting synchronous inner wheel 33 mesh with the supporting synchronous gear 323.
