Description

Technical Field

[0001] This utility model relates to a silent burner. Background Technology

[0002] A burner is a thermal energy device that delivers fuel and air into the furnace at the required concentration, velocity, turbulence and mixing method, and enables the fuel to be stably ignited and burned in the furnace.

[0003] Existing burners suffer from significant noise and unstable flames due to defects in the design of their flame outlets. Utility Model Content

[0004] The purpose of this utility model is to provide a technical solution for a silent burner that addresses the shortcomings of existing technologies. Through the design of densely arranged flame outlets, the noise during burner combustion can be greatly reduced, making the combustion of the burner head more stable and reliable.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] Silent burners, including

[0007] Stove head;

[0008] Its features are:

[0009] The inner plate of the burner head has at least two layers of flame outlets arranged in a ring, with the upper and lower adjacent layers of flame outlets staggered. The dense arrangement of flame outlets can greatly reduce the noise of the burner during combustion, making the combustion of the burner head more stable and reliable.

[0010] Furthermore, the inner plate is provided with at least one layer of flame stabilizing holes, which are located below the flame outlet holes. This helps to improve the stability of the flame during combustion and prevent the flame from leaving the flame.

[0011] Furthermore, the burner head also includes an outer plate and a second bottom plate connected to the inner plate, and a first plate connected to the outer plate. The outer plate, the inner plate, the first bottom plate, and the second bottom plate cooperate to form a flow guide cavity for transporting the mixed gas. The flow guide cavity is used to supply gas to the flame outlet and the flame stabilizer, ensuring that the mixed gas flows along the flow guide cavity to the flame outlet and the flame stabilizer, so that the flame is stable and reliable.

[0012] Furthermore, it also includes a first ejector tube, which is connected to the first base plate and is used to supply air to the guide cavity.

[0013] Furthermore, it also includes a second ejector tube and a second gas inlet connector. The second ejector tube is connected to the second base plate, with its top end protruding from the top surface of the second base plate. The bottom end of the second ejector tube penetrates the second base plate and extends into the first ejector tube. The second gas inlet connector passes through the first ejector tube and connects to the second ejector tube. The bottom of the second ejector tube is provided with an inclined cut. Through the second gas inlet connector, gas can be ejected upward from the center of the burner head through the second ejector tube to achieve small-flame combustion. At the same time, part of the air in the first ejector tube and the gas mixture are transported from the bottom end to the top end of the second ejector tube through the inclined cut, improving combustion efficiency.

[0014] Furthermore, the first ejector tube includes an arc section, a straight section, and an inclined section. The arc section is connected to the inclined section through the straight section. The design of the straight section facilitates the full mixing of gas and air, improving the combustion efficiency of the burner. The inclined section is designed with a 45° inclination, which facilitates the premixing of the blast airflow with the gas, lengthens the air intake distance, and adjusts the air intake airflow of the inclined section, thus buffering the airflow, effectively reducing noise, and achieving a silent effect.

[0015] Furthermore, the straight pipe section is equipped with a first gas inlet connector, which extends into the interior of the straight pipe section. The first gas inlet connector is provided with an outlet hole located inside the straight pipe section, which is conducive to the stable input of gas into the first injector tube and facilitates mixing with air. The outlet hole is distributed in the direction of gas and air movement to improve the mixing effect.

[0016] Furthermore, a first air intake connector is provided on the straight pipe section between the first gas intake connector and the inclined section. A drain pipe is provided on the first base plate, and the drain pipe passes through the second base plate. The top of the drain pipe is flush with the top surface of the second base plate. A second air intake connector is provided on the drain pipe. The second air intake connector is connected to the first air intake connector through a gas supply pipe to supplement secondary air into the burner. The air in the inclined section is supplied to the burner through the drain pipe via the first air intake connector, the gas supply pipe, and the second air intake connector, greatly improving the efficiency of flame combustion. At the same time, water droplets or oil stains falling from the pot can be discharged through the drain pipe. The inclined design between the second air intake connector and the drain pipe prevents oil stains and water droplets from entering the gas supply pipe and affecting the air delivery effect.

[0017] Furthermore, the inclined section is equipped with a mounting plate and an air damper regulating valve. The mounting plate is used to install the blower, and the air input volume is adjusted through the air damper regulating valve.

[0018] Furthermore, a limiting hole is provided between the first base plate and the second base plate for installing the ignition needle and thermocouple.

[0019] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0020] 1. This utility model, through its densely arranged flame outlet design, can greatly reduce the noise of the burner during combustion, making the combustion of the burner head more stable and reliable.

[0021] 2. The outer side plate, inner side plate, first base plate and second base plate are fitted together to form a flow guide cavity for transporting mixed gas. The flow guide cavity is used to supply gas to the flame outlet and flame stabilization hole, ensuring that the mixed gas flows along the flow guide cavity to the flame outlet and flame stabilization hole, so that the flame is stable and reliable.

[0022] 3. The straight pipe section design facilitates thorough mixing of gas and air, improving burner combustion efficiency. The 45° inclined section design facilitates premixing of the blower airflow with the gas, lengthens the air intake distance, and adjusts the airflow of the inclined section to buffer the airflow, effectively reducing noise and achieving a silent effect.

[0023] 4. The air in the inclined section is supplied to the inside of the burner through the first air inlet connector, the air supply pipe, and the second air inlet connector via the drain pipe, greatly improving the efficiency of flame combustion. At the same time, water droplets or oil stains falling from the pot can be discharged through the drain pipe. The inclined design between the second air inlet connector and the drain pipe prevents oil stains and water droplets from entering the air supply pipe and affecting the air delivery effect.

[0039] like Figures 1 to 6 As shown, the silent burner of this utility model includes a burner head 1, a first ejector tube 2 and a second ejector tube 105, both of which are connected to the burner head 1.

[0040] The inner side plate 102 of the burner head 1 has at least two layers of flame outlet holes 8 arranged in a ring, with the upper and lower adjacent layers of flame outlet holes 8 arranged alternately. Through the dense arrangement of flame outlet holes 8, the noise of the burner during combustion can be greatly reduced, making the combustion of the burner head 1 more stable and reliable.

[0041] The flame outlet 8 has a semi-circular arc structure. This application adopts an 8-layer design with 480 flame outlets 8.

[0042] The inner plate 102 is provided with at least one layer of flame stabilizing holes 7. This application uses one layer of six flame stabilizing holes 7 as an example for explanation. The flame stabilizing holes 7 are located below the flame outlet holes 8, which helps to improve the stability of the flame during combustion and prevent the flame from leaving the flame.

[0043] The burner head 1 also includes an outer plate 101 and a second bottom plate 104 connected to the inner plate 102, and a first plate connected to the outer plate 101. The outer plate 101, the inner plate 102, the first bottom plate 103 and the second bottom plate 104 cooperate to form a flow guide cavity 105 for transporting mixed gas. The flow guide cavity 105 is used to supply gas to the flame outlet 8 and the flame stabilizing hole 7, ensuring that the mixed gas flows along the flow guide cavity 105 to the flame outlet 8 and the flame stabilizing hole 7, so that the flame is stable and reliable.

[0044] The outer side plate 101, the inner side plate 102, the first bottom plate 103, and the second bottom plate 104 are integrally formed, which facilitates the overall processing and manufacturing of the furnace head 1.

[0045] A limiting hole 5 is provided between the first base plate 103 and the second base plate 104 for installing an ignition needle and a thermocouple.

[0046] The first ejector tube 2 is connected to the first base plate 103 and is used to supply air to the guide cavity 105.

[0047] The first ejector tube 2 includes an arc section 203, a straight section 201, and an inclined section 202. The arc section 203 is connected to the inclined section 202 through the straight section 201. The design of the straight section 201 facilitates the full mixing of gas and air, improving the combustion efficiency of the burner head 1. The inclined section 202 is designed with a 45° inclination, which facilitates the premixing of the blower airflow with the gas, lengthens the air intake distance, and adjusts the air intake airflow of the inclined section 202 to buffer the airflow, effectively reduce noise, and achieve a silent effect.

[0048] The straight pipe section 201 is provided with a first gas inlet connector 206, which extends into the interior of the straight pipe section 201. The first gas inlet connector 206 is provided with an outlet hole 208 located inside the straight pipe section 201, which is conducive to the stable input of gas into the first injector pipe 2 and facilitates mixing with air. The outlet hole 208 is distributed in the direction of gas and air movement to improve the mixing effect.

[0049] A first air inlet connector 204 is provided on the straight pipe section 201 between the first gas inlet connector 206 and the inclined section 202. A drain pipe 6 is provided on the first base plate 103. The drain pipe 6 passes through the second base plate 104, and the top of the drain pipe 6 is flush with the top surface of the second base plate 104. A second air inlet connector 601 is provided on the drain pipe 6. The second air inlet connector 601 is connected to the first air inlet connector 204 through the gas supply pipe and the second air inlet connector 601 to supplement secondary air into the burner head 1. The air in the inclined section 202 is supplied to the burner head 1 through the first air inlet connector 204, the gas supply pipe and the second air inlet connector 601 through the drain pipe 6, which greatly improves the efficiency of flame combustion. At the same time, water droplets or oil stains falling from the pot can be discharged through the drain pipe 6. The inclined design between the second air inlet connector 601 and the drain pipe 6 prevents oil stains and water droplets from entering the gas supply pipe and affecting the air delivery effect.

[0050] The inclined section 202 is equipped with a mounting plate 3 and a damper regulating valve 207. The mounting plate 3 is used to install the blower and the damper regulating valve 207 is used to regulate the air input.
