Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnace burners, in particular to an annealing furnace burner with sufficient combustion. Background Technique

[0002] The annealing furnace burner is one of the key equipment for annealing metal materials. The annealing furnace burner usually adopts gas combustion technology, using natural gas, liquefied petroleum gas (LPG) or other combustible gases as fuels, and generates high-temperature flames by mixing with air and then igniting. Annealing is a heat treatment process. By heating, holding, and cooling processes, the internal tissue structure of metal materials is changed, so as to achieve the purposes of reducing hardness, improving plasticity and toughness, eliminating internal stress, etc.

[0003] However, when using the annealing furnace burner, the situation of insufficient material combustion may occur. Insufficient combustion means that the fuel is not completely converted into heat energy, resulting in energy waste, increasing production costs, unstable temperature control, and pollutants in the combustion products may affect the effect of annealing treatment, resulting in a decline in the performance of metal materials, affecting product quality, and lower use efficiency. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an annealing furnace burner with sufficient combustion.

[0005] The utility model is realized by adopting the following technical solutions: an annealing furnace burner with sufficient combustion, including a mixing mechanism, a conveying mechanism, and a housing mechanism. The mixing mechanism is located on the inner wall of the housing mechanism, the conveying mechanism is located inside the housing mechanism, and the mixing mechanism is located at the left end of the conveying mechanism;

[0006] The mixing mechanism includes a first baffle. The right end of the first baffle is fixedly connected with a mixing sleeve.

The inner wall of the air vent ring is communicated with a blower. The inner wall of the air vent ring is communicated with an air inlet pipe. The surface of the air inlet pipe is fixedly connected with an air inlet connecting pipe. The right end of the air inlet connecting pipe is fixedly connected with a first connecting ring.

[0007] Through the above technical solutions, high-pressure gas is sent into the air vent ring through the air inlet pipe and then blown out along the output end of the blower. Because of the installation angle of the blower, the air flow forms a vortex inside the air vent ring, further stirring and mixing the combustible mixture, so as to make it burn more fully, improving the practicability.

[0008] As a further improvement of the above solution, the air inlet connecting pipe is located at the right end of the second baffle. The inside of the air vent ring is hollow. The surface of the air inlet pipe is fixedly connected with the inner wall of the second baffle.

[0009] Through the above technical solution, the hollow ventilation ring can distribute the gas entering from the intake pipe to each blower on its inner wall, making the structure more reasonable and the use more convenient.

[0010] As a further improvement of the above solution, the conveying mechanism includes a second connecting ring. The left end of the second connecting ring is fixedly connected with an air connecting pipe. The left end of the air connecting pipe is fixedly connected with a conveying pipe. A protective ring is fixedly connected to the surface of the conveying pipe. A fuel pipe is fixedly connected to the upper end of the protective ring. A fuel connecting pipe is fixedly connected to the surface of the fuel pipe.

[0011] Through the above technical solution, the air passing through the cavity connecting pipe is initially mixed with the atomized fuel sprayed by the atomizing nozzle below the fuel pipe and drives the mixed combustible mixture into the subsequent steps, making the use more convenient and improving the practicability.

[0012] As a further improvement of the above solution, an atomizing nozzle is arranged inside the protective ring. The output end of the atomizing nozzle is located inside the conveying pipe. The left end of the conveying pipe is fixedly connected with the right end of the second baffle.

[0013] Through the above technical solution, the atomizing nozzle can atomize the fuel and send the atomized fuel into the conveying pipe, optimizing the overall structure and making the use more reasonable.

[0014] As a further improvement of the above solution, the housing mechanism includes a fire outlet pipe. The right end of the fire outlet pipe is fixedly connected with an outer shell. A third connecting ring is fixedly connected to the surface of the outer shell. The right end of the outer shell is fixedly connected with a connecting bottom plate. A fireproof partition is fixedly connected to the inner wall of the outer shell.

[0015] Through the above technical solution, the flame is guided through the fire outlet pipe, and the fireproof partition is used to protect the outer shell and other components. The outer shell itself is fixed and connected to other devices or components through the connecting bottom plate and the third connecting ring, making the overall structure more stable and the use more convenient.

[0016] As a further improvement of the above solution, the inner wall of the outer shell is fixedly connected to the surface of the fuel pipe. The inner wall of the connecting bottom plate is fixedly connected to the surface of the air connecting pipe. The third connecting ring is located at the left end of the fuel pipe.

[0017] Through the above technical solution, by fixedly connecting the inner wall of the bottom plate to the surface of the air connecting pipe, more protection is provided inside to prevent internal damage.

[0018] As a further improvement of the above solution, the surface of the mixing sleeve is fixedly connected to the inner wall of the outer shell. The surface of the air intake pipe is fixedly connected to the inner wall of the connecting bottom plate. The air intake pipe is located below the conveying pipe.

[0019] Through the above technical solution, the fixed connection between the surface of the mixing sleeve and the inner wall of the housing can make the structure more stable during further mixing, improving practicability.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] In the present utility model, by setting a mixing mechanism, specifically, the combustible mixture after mixing enters the inside of the mixing sleeve under the push of the intake pipe. At this time, the high-pressure gas pipe connected to the intake connection pipe starts to input air. The high-pressure air enters the inside of the ventilation ring along the intake through pipe, and then the high-pressure air blows out along the output end of the blower to form an air vortex, thereby driving the combustible mixture to rotate and stir, making it further mixed and further improving the effect of its full combustion.

[0022] In the present utility model, by setting a conveying mechanism, specifically, the fuel conveying pipeline is fixed by the fuel connection pipe connected to the surface of the fuel pipe to provide fuel inside, the air connection pipe is used to fixedly connect the intake pipe to convey air inside the device, and the first connection ring connected to the right end of the intake connection pipe is used to connect the high-pressure gas pipe. After the pipeline connection is completed, the fuel flows through the fuel pipe to the atomizing nozzle, and the atomized fuel is sprayed inside the conveying pipe by squeezing the atomizing nozzle. At the same time, the intake pipe connected to the air connection pipe starts to convey air into the inside through the conveying pipe. At this time, the atomized fuel and air are preliminarily mixed inside the conveying pipe. Brief Description of the Drawings
