Description
Technical Field
[0001] The utility model relates to the field of low - nitrogen burners, and specifically relates to a low - nitrogen burner for liquid fuel. Background Technique
[0002] Burners are classified into industrial burners, combustion machines, domestic burners, and special burners according to types and application fields. They are mostly made of corrosion - resistant and high - temperature - resistant materials such as stainless steel or titanium metal. The function of the burner is to atomize the sample through flame combustion. The atomized test solution enters the burner. Under the action of flame temperature and flame atmosphere, through processes such as drying, melting, evaporation, and dissociation, a large number of ground - state atoms, as well as some excited - state atoms, ions, and molecules are generated. A well - designed burner should have the properties of high atomization efficiency, low noise, and stable flame to ensure high absorption sensitivity and measurement precision.
[0003] Existing low - nitrogen burners also belong to burners. By adjusting the combustion air and the burner head, the best combustion parameters can be obtained, and then through single - stage fire, two - stage fire, and two - stage fire progressive proportional adjustment, the burner can obtain appropriate firepower, so that it can adapt to any type of combustion chamber. A servo motor can also be used to adjust the air flow in the first or second stage. However, in the actual use process, the air flow rate in the existing low - nitrogen burner is too fast, resulting in the difficulty of the internal liquid fuel to be fully mixed with air, incomplete combustion of the mixed fuel after ignition, a large amount of waste of liquid fuel, and an increase in its overall combustion cost.
[0004] To sum up, in the above - mentioned structure, the internal liquid fuel is difficult to be fully mixed with air during use, resulting in incomplete combustion of the mixed fuel after ignition, a large amount of waste of liquid fuel, and an increase in its overall combustion cost. Content of the Utility Model
[0005] Based on this, the purpose of the present utility model is to provide a low - nitrogen burner for liquid fuel to solve the technical problems that the internal liquid fuel is difficult to be fully mixed with air during use, resulting in incomplete combustion of the mixed fuel after ignition, a large amount of waste of liquid fuel, and an increase in its overall combustion cost.
[0006] To achieve the above - mentioned purpose, the present utility model provides the following technical solution: A low - nitrogen burner for liquid fuel, including a burner body. An air inlet mechanism is arranged on one side of the burner body, and a liquid fuel tank is arranged on the other side of the burner body. The output end of the liquid fuel tank is connected with an atomizing pipe, and the atomizing pipe penetrates into the burner body. A stirring mechanism is rotatably arranged in the burner body, and a branch pipe communicated with the atomizing pipe is arranged in the stirring mechanism. A plurality of groups of nozzles are connected to the branch pipe through the stirring mechanism.
[0007] By adopting the above technical solution, during the startup process of the fan, the outside air is driven into the burner body. At the same time, relying on the wind force, the stirring mechanism is driven to rotate inside the burner body to achieve full disturbance of the internal air. And under the action of the atomizing pipe, the liquid fuel in the liquid fuel tank is atomized, so that the atomized liquid fuel is discharged towards the nozzle under the action of the branch pipe. Under the action of the nozzle, the atomized fuel is fully mixed with the internally disturbed air, greatly reducing the waste of liquid fuel.
[0008] The present utility model is further configured such that the air inlet mechanism is a fan, and the fan is used to suck the outside air into the inside of the burner body.
[0009] By adopting the above technical solution, under the action of the fan, it is convenient for the staff to control the air intake volume inside the burner body, further improving the overall operation stability of the device.
[0010] The present utility model is further configured such that the stirring mechanism includes a stirring shaft and stirring plates. The atomizing pipe is located inside the stirring shaft, and stirring plates are connected to the outer wall of the stirring shaft.
[0011] By adopting the above technical solution, the air sucked in during the operation of the fan blows against the outer wall of the stirring plate. At this time, the stirring plate drives the stirring shaft to rotate, thereby realizing the large-range disturbance of the air inside the burner body by the stirring plate.
[0012] The present utility model is further configured such that the branch pipe is hermetically arranged inside the stirring plate.
[0013] By adopting the above technical solution, the hermetically arranged branch pipe can effectively prevent the atomized liquid fuel from leaking, and at the same time effectively reduce the waste of liquid fuel.
[0014] The present utility model is further configured such that the stirring plates are arranged in an arc shape on the outer wall of the stirring shaft.
[0015] By adopting the above technical solution, when the fan is started, the outside air is blown into the inside of the burner body. During this process, the stirring plate itself will first contact the air flow. Since the stirring plate is arranged in an arc shape, it is more convenient for the incoming air flow to drive the stirring plate to rotate. In this process, it can effectively prevent the stirring plate from getting stuck with the stirring shaft, further improving the overall practicality of the device.
[0016] The present utility model is further configured such that a connecting pipe is installed at one end of the burner body.
[0017] By adopting the above technical solution, under the action of the connecting pipe, the liquid fuel for internal combustion can enter the combustion chamber through the connecting pipe, further reducing the overall combustion cost.
[0018] The present utility model is further configured such that a feed port is provided on the outer wall of the liquid fuel tank.
[0019] By adopting the above technical solution, through the feed port, it is convenient for the staff to add liquid fuel to the liquid fuel tank subsequently, improving the overall practicality of the device.
[0020] The present utility model is further configured such that the atomizing pipe and the liquid fuel tank are detachably arranged.
[0021] By adopting the above technical solution, during long-term use, it is convenient for the staff to disassemble and replace the atomizing pipe.
[0022] In summary, the present utility model mainly has the following beneficial effects:
[0023] In the present utility model, a stirring mechanism is rotatably arranged on the inner wall of the burner body. During the startup of the fan, the outside air is driven into the burner body. At the same time, relying on the wind force, the stirring mechanism is driven to rotate in the burner body, realizing sufficient disturbance of the internal air. And under the action of the atomizing pipe, the liquid fuel in the liquid fuel tank is atomized. The atomized liquid fuel will be discharged towards the nozzle under the action of the branch pipe. Under the action of the nozzle, the atomized fuel is fully mixed with the internally disturbed air, greatly reducing the waste of liquid fuel. Description of the Drawings

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.
[0030] The embodiments of the present utility model will be described below according to its overall structure.
[0031] Embodiment 1
[0032] A low-nitrogen burner for liquid fuel, as Figures 1-3 shown, includes a burner body 1, a liquid fuel tank 3, a connecting pipe 4, a stirring mechanism and a mixing mechanism. A blower 2 is provided on one side of the burner body 1. During use, the blower 2 on one side is started to discharge the gas in the external air into the burner body 1. In this process, it is convenient for the subsequent liquid fuel and air to be fully mixed. Since a stirring mechanism is rotatably provided in the burner body 1, when the gas flows in the burner body 1, it will drive the stirring plate 6 on the stirring mechanism to rotate, realizing full disturbance of the internal air. A liquid fuel tank 3 is provided on the other side of the burner body 1. An atomizing pipe 9 is connected to the output end of the liquid fuel tank 3, and the atomizing pipe 9 penetrates into the burner body 1 and is located inside the stirring shaft 7 of the stirring mechanism. And a branch pipe 8 communicating with the atomizing pipe 9 is provided in the stirring plate 6. A plurality of groups of nozzles 5 are connected to the branch pipe 8 through the stirring plate 6. And under the action of the atomizing pipe 9, the liquid fuel in the liquid fuel tank 3 is atomized, so that the atomized liquid fuel will be discharged to the nozzles 5 under the action of the branch pipe 8. Through the action of the nozzles 5, the atomized fuel is fully mixed with the internally disturbed air, greatly reducing the waste of liquid fuel. At the same time, a connecting pipe 4 is installed at one end of the burner body 1. Under the action of the connecting pipe 4, it is convenient for the liquid fuel burning inside to enter the combustion chamber through the connecting pipe 4, further reducing the overall combustion cost.
[0033] Please refer to Figure 2 , wherein the stirring mechanism includes a stirring shaft 7 and a stirring plate 6, and the atomizing pipe 9 is located inside the stirring shaft 7, and the stirring plate 6 is connected to the outer wall of the stirring shaft 7. The air inhaled during the operation of the blower 2 will blow to the outer wall of the stirring plate 6. At this time, the stirring plate 6 will drive the stirring shaft 7 to rotate, thereby realizing the large-range disturbance of the air in the burner body 1 by the stirring plate 6.
[0034] Embodiment 2
[0035] As Figure 4A low-nitrogen burner for liquid fuel is shown. The overall structure is similar to that of the embodiment. The stirring plate 6 is arranged in an arc shape on the outer wall of the stirring shaft 7. When the blower 2 is started, the outside air will be blown into the interior of the burner body 1. During this process, the stirring plate 6 itself will first come into contact with the air flow. Since the stirring plate 6 is arranged in an arc shape, it is more convenient for the incoming air flow to drive the stirring plate 6 to rotate. During this process, the situation where the stirring plate 6 is stuck with the stirring shaft 7 can be effectively prevented, further improving the overall practicality of the device.
[0036] The working principle of the present utility model is as follows: During use, by starting the blower 2 on one side of the burner body 1, under the action of the blower 2, the outside gas is introduced into the burner body 1. By relying on the wind force of the blower 2 itself, the stirring plate 6 can be driven to rotate. During this process, the stirring plate 6 disturbs the gas in the burner body 1. At the same time, under the action of the atomizing tube 9, the liquid fuel in the liquid fuel tank 3 is atomized. At this time, the atomized liquid fuel will be discharged from the atomizing tube 9 to the branch pipe 8 in the stirring plate 6. Subsequently, under the action of multiple nozzles 5, the spraying area of the liquid fuel is increased, so that the atomized fuel is fully mixed with the internally disturbed air, greatly reducing the waste of the liquid fuel.
[0037] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and do not limit the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present utility model, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed.
