Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial combustion equipment technology, and specifically relates to a simplified air supply structure for a burner nozzle. Background Technology
[0002] As a specialized device for achieving precise mixing and efficient combustion of fuel and air, the burner has been widely used in many fields such as industrial manufacturing, civil heating, and special working conditions. In the structure of the burner, the burner nozzle is the core component, which is generally equipped with a UV ultraviolet detector. Its core function is to monitor whether the flame is normal in real time and prevent gas leakage from causing danger.
[0003] However, in the existing technology, UV detectors are usually connected to an air compressor for air supply. The presence of the air compressor significantly increases the cost and occupies additional installation space. In addition, there are noise and energy consumption issues during operation, which greatly increase the system complexity and subsequent maintenance costs. To solve the above problems, we provide a simplified air supply structure for burner nozzles. Utility Model Content
[0004] The purpose of this invention is to provide a simplified air supply structure for a burner nozzle, in order to solve the problem mentioned in the background art that the UV detector in the prior art needs to rely on an air compressor for air supply.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a simplified air supply structure for a burner nozzle, comprising a burner nozzle body, a mounting base bolted to one side of the burner nozzle body, a three-way connector fixedly connected to one side of the mounting base, a UV detector fixedly connected to the other end of the three-way connector, a main air inlet pipe fixedly connected to the top of the burner nozzle body, a fan bolted to the top of the main air inlet pipe, an air distribution interface fixedly connected to the surface of the main air inlet pipe, an air supply hose fixedly sleeved on the surface of the air distribution interface, the other end of the air supply hose communicating with the three-way connector, and an ignition needle fixedly connected to one end of the mounting base.
[0006] Preferably, a flame viewing mirror is fixedly connected to one side of the mounting base. The flame viewing mirror is composed of a high-temperature resistant quartz glass lens and a metal protective frame.
[0007] Preferably, the connection ends of the main air inlet pipe and the fan are equipped with matching flange structures, and the sealing connection is achieved by adding a sealing gasket to the flange.
[0008] Preferably, one side of the mounting base is connected to a flame jet pipe, and the bottom of the mounting base is connected to a gas inlet pipe.
[0009] This utility model has the following beneficial effects:
[0010] This device, by adopting a main air inlet duct distribution design, replaces the traditional independent air compressor structure for UV detector replenishment, significantly reducing equipment procurement, installation, and maintenance costs. By eliminating the independent air compressor, the overall system energy consumption is reduced, while the noise generated by the air compressor is also reduced. By integrating combustion air supply and detection replenishment functions into the same air path system, the device simplifies the equipment structure, improves system reliability, and reduces failure points. While ensuring flame combustion stability and monitoring accuracy, it achieves multi-dimensional improvements in equipment cost optimization, operational efficiency enhancement, and maintenance convenience, making it suitable for various industrial burner scenarios.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.
[0015] Example 1:
[0016] refer to Figures 1-2 A simplified air supply structure for a burner nozzle includes a burner nozzle body 1, a mounting base 2 bolted to one side of the burner nozzle body 1, a three-way connector 3 fixedly connected to one side of the mounting base 2, a UV detector 4 fixedly connected to the other end of the three-way connector 3, a main air inlet pipe 5 fixedly connected to the top of the burner nozzle body 1, a fan 6 bolted to the top of the main air inlet pipe 5, an air distribution interface 7 fixedly connected to the surface of the main air inlet pipe 5, an air supply hose 8 fixedly sleeved on the surface of the air distribution interface 7, and the other end of the air supply hose 8 communicating with the three-way connector 3. An ignition needle 9 is fixedly connected to one end of the mounting base 2, and the ignition needle 9 is fixed inside the burner nozzle body 1 by an insulating bracket for generating a high-voltage electric spark to ignite the mixture of fuel and air.
[0017] Specifically, the main air intake duct 5 is connected to the flame jet pipe 11 to supply the air required for combustion, the gas intake duct 12 is connected to the flame jet pipe 11 to supply fuel, the flame sight glass 10 is set opposite to the flame area of the flame jet pipe 11 to observe the combustion state, the detection end of the UV detector 4 is oriented towards the flame jet pipe 11 along the flame center axis, and the detection range covers the flame combustion area, the fan 6 continuously provides stable pressure combustion air through the main air intake duct 5, the discharge end of the ignition needle 9 extends into the fuel mixing area, the ignition needle 9 is electrically connected to the ignition controller through a high-voltage wire to generate a high-voltage electric spark to ignite the mixture of fuel and air, the gas enters through the gas intake duct 12, and is then atomized by the gas nozzle in the burner burner body 1 and delivered to the flame jet pipe 11 to mix with the air input from the main air intake duct 5. The main air duct air distribution design replaces the traditional independent air compressor to supply air to the UV detector 4, which not only saves the purchase and installation costs of the air compressor, but also reduces energy consumption and noise during equipment operation, greatly reducing equipment costs.
[0018] refer to Figure 2 A flame inspection mirror 10 is fixedly connected to one side of the mounting base 2. The flame inspection mirror 10 is composed of a high-temperature resistant quartz glass lens and a metal protective frame. The central axis of the flame inspection mirror 10 forms an angle of 30-45° with the flame center of the flame jet tube 11, which makes it easy for the operator to observe the flame combustion pattern directly.
[0019] refer to Figure 1 Both the main air inlet duct 5 and the fan 6 are equipped with matching flange structures, and the flanges are sealed with gaskets to improve the sealing performance. The fan 6 provides a stable pressure of combustion air through the main air inlet duct 5. The main air inlet duct 5 can be equipped with a flow regulating valve, which is a manual butterfly valve or a solenoid regulating valve. It is used to regulate the air intake of the main air inlet duct 5 and the air intake of the branch air supply hose 8 to ensure that the air supply meets the requirements of purging, cooling and combustion.
[0020] refer to Figure 2 One side of the mounting base 2 is connected to a flame jet pipe 11, and the bottom of the mounting base 2 is connected to a gas inlet pipe 12. A gas flow control valve can be installed inside the gas inlet pipe 12. After the gas enters through the gas inlet pipe 12, the flow rate is regulated by the gas flow control valve.
[0021] Brief description of the operation: The blower 6 continuously delivers combustion air through the main air intake pipe 5. The gas enters the burner nozzle body 1 through the gas intake pipe 12 and is atomized. It mixes with the air in the flame jet pipe 11. The ignition needle 9 generates an electric spark under the action of the ignition controller to ignite the gas mixture and form a flame. The flame sight glass 10 is used to directly observe the combustion state. The UV detector 4 is aligned with the combustion area along the flame axis to monitor the flame stability in real time. The device adopts the air distribution design of the main air intake pipe 5, which provides the required air for the combustion process and the UV detector 4 at the same time. It replaces the traditional independent air compressor to supplement the air for the detector. It not only saves the purchase and installation costs of the air compressor, but also significantly reduces the energy consumption and noise of the equipment, and realizes efficient combustion monitoring and equipment cost optimization.
