Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a combined gas burner nozzle. Background Art

[0002] A gas burner is a device that uses gas as fuel to convert chemical energy into thermal energy. Specifically, the working principle of a gas burner is to spray gas into the burner, mix it with air, and then burn it through an ignition device. Subsequently, the high-temperature gas generated is heat exchanged through a heat exchanger and outputs heat energy. The gas burner nozzle is a key component in the gas burner. Its function is to transport the gas into the combustion chamber and convert the potential energy (i.e. pressure) of the gas into kinetic energy (i.e. speed) to form an appropriate gas jet. After this jet is mixed with air, it burns in the combustion chamber and releases heat energy.

[0003] Most existing burner nozzles are fixed in one direction for use. Since different combustion conditions and gas types require different nozzles, if the nozzles are not adjusted regularly, they may not be able to adapt to different flame shape and size requirements, resulting in poor flame stability. Flame fluctuations or extinction may cause safety hazards and affect the continuity and stability of the combustion process.

[0004] Therefore, since most of the existing burner nozzles are fixed in one direction for use, and different nozzles are required for different combustion conditions and gas types, if the nozzles are not adjusted regularly, it may lead to poor flame stability and easily cause safety hazards. A combined gas burner nozzle can be designed with multiple adjustable nozzle openings to improve flame stability. Utility Model Content

[0024] See also Figure 2 In this embodiment, a mounting ring plate 101 is installed at one end of the first mixing chamber 1 away from the second mixing chamber 2, and a plurality of mounting holes 102 are arranged around the upper edge of the mounting ring plate 101. The screws are first passed through the mounting holes 102 to fix the mounting ring plate 101 to the burner. During the use of the burner, the fuel and the combustion-supporting agent are first preliminarily mixed in the first mixing chamber 1. A plurality of first clamping holes 103 are arranged around the edge of one end of the first mixing chamber 1 close to the second mixing chamber 2. A first diverter plate 104 is installed on the inside of the first mixing chamber 1. The first diverter plate 104 can preliminarily make the discharge uniform, thereby improving the combustion efficiency of the fuel.

[0025] See also Figure 3-Figure 4 3. In this embodiment, the second mixing chamber 2 is provided with a first clamping column 201 corresponding to the first clamping hole 103 near the edge of one end of the first mixing chamber 1, and the first clamping column 201 drives the second mixing chamber 2 to be positioned and connected with the first mixing chamber 1 through the first clamping hole 103. When the first mixing chamber 1 is fixed, the second mixing chamber 2 is picked up, and the first clamping column 201 drives the second mixing chamber 2 to be positioned and connected with the first mixing chamber 1 through the first clamping hole 103. The second mixing chamber 2 is provided with a filter plate 202 near one end of the first mixing chamber 1, and a second diverter plate 203 is provided at one end of the second mixing chamber 2 away from the first mixing chamber 1. When the fuel and the combustion-supporting agent enter the second mixing chamber 2, the large particles of impurities in the combustion-supporting agent or the fuel are first filtered through the filter plate 202, and then enter the second mixing chamber 2 for further sufficient mixing, and then the discharge can be further made more uniform through the second diverter plate 203, and finally enter the connecting pipe 3.

[0026] See also Figure 5 In this embodiment, the fixed module includes an arc-shaped clamping plate 401, a connecting shaft 402, an arc-shaped rubber pad 403, a fixing plate 404, a fixing column 405 and a nut 406. The arc-shaped clamping plates 401 are arranged in a transverse symmetrical manner. A connecting shaft 402 is installed at one end of the connection between the two sets of arc-shaped clamping plates 401, and an arc-shaped rubber pad 403 is installed on the inner side of the arc-shaped clamping plate 401. When the first mixing chamber 1 and the second mixing chamber 2 are positioned and connected, the arc-shaped clamping plate 401 is lifted and rotated by the connecting shaft 402. This arc-shaped rubber pad 403 continuously approaches and fits the connection between the first mixing chamber 1 and the second mixing chamber 2. A fixing plate 404 is installed on the upper end of the arc-shaped clamping plate 401. A fixing column 405 is passed through the middle of the fixing plate 404. Nuts 406 are respectively provided on the outside of the two ends of the fixing column 405. The fixing column 405 is passed through the fixing plate 404 and then tightened and fixed by the nuts 406. During this process, the arc-shaped rubber pad 403 can increase friction, prevent the first mixing chamber 1 and the second mixing chamber 2 from shaking, and improve the stability of the burner during use.

[0027] During operation, first screw through the mounting hole 102 to securely connect the mounting ring plate 101 to the burner. Then, pick up the second mixing chamber 2. The first clamping column 201 drives the second mixing chamber 2 to be positioned and connected to the first mixing chamber 1 through the first clamping hole 103.

[0028] After the first mixing chamber 1 and the second mixing chamber 2 are positioned and connected, the arc-shaped clamping plate 401 is lifted and rotated via the connecting shaft 402, so that the arc-shaped rubber pad 403 continuously approaches and fits the connection between the first mixing chamber 1 and the second mixing chamber 2. Then, the fixing column 405 is passed through the fixing plate 404 and then tightened with the nut 406. During this process, the arc-shaped rubber pad 403 can increase friction to prevent the first mixing chamber 1 and the second mixing chamber 2 from shaking.

[0029] After the first mixing chamber 1 and the second mixing chamber 2 are reinforced, an appropriate number of extension tubes 303 are selected according to the length of the nozzle body 307 required for gas ejection. First, pick up a group of extension tubes 303 and move the second clamping holes 304 on the extension tubes 303 along the second plug-in column 302, so that the extension tubes 303 are positioned and connected with the mounting tube 301. Then, the remaining extension tubes 303 are arranged horizontally. At the same time, the third plug-in column 305 drives one group of extension tubes 303 to be positioned and connected with the other group of extension tubes 303 through the second clamping holes 304. If the nozzle body 307 is picked up, the third clamping hole 306 on the nozzle body 307 is moved along the third plug-in column 305, so that the nozzle body 307 is positioned and connected with the extension tubes 303, and then it can be used.

[0030] During the use of the burner, the fuel and the combustion aid are first preliminarily mixed in the first mixing chamber 1, and the discharge can be preliminarily made uniform through the first diverter plate 104. When the fuel and the combustion aid enter the second mixing chamber 2, the large particles of impurities in the combustion aid or the fuel are first filtered through the filter plate 202, and then enter the second mixing chamber 2 for further thorough mixing. Then, the discharge can be further made more uniform through the second diverter plate 203, and finally enter the connecting pipe 3 and be sprayed out through the nozzle body 307.

[0031] Through the above steps, the first mixing chamber 1 is first fixedly connected to the burner, and then the second mixing chamber 2 is positioned and connected to the first mixing chamber 1. The first mixing chamber 1 and the second mixing chamber 2 are then reinforced by the fixed module. Finally, the nozzle body 307 on the connecting pipe 3 is adjusted to an appropriate length and can be used. Through multiple adjustable nozzle openings, it can be adjusted according to the type of gas and combustion requirements to ensure the optimal mixing ratio of gas and air, thereby improving combustion efficiency. This adjustment capability enables the burner to adapt to different flame shapes and size requirements, achieve more efficient combustion, and improve flame stability. At the same time, by precisely controlling the injection and mixing process of the gas, the combined nozzle helps to reduce safety hazards caused by incomplete combustion or gas leakage. This is of great significance for ensuring the safety of equipment and personnel, so as to solve the problem that most existing burner nozzles are fixed in one direction for use. Since different combustion conditions and gas types require different nozzles, if the nozzles are not adjusted, it may lead to poor flame stability and easily cause safety hazards.
