Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy furnace head technology, and in particular to an internal swirling aluminum alloy furnace head. Background Technology

[0002] "Internal swirl flame" is a combustion technology used in gas stoves. Simply put, it involves a specially structured burner and a unique airflow mixing method that causes the gas to swirl inwards from the edge of the combustion zone during combustion. This flame is called "internal swirl flame," and its formal name is "swirl-concentrated combustion technology." The burner has a concave structure, and the special burner structure and airflow mixing method ensure more thorough mixing of the gas and air, resulting in more complete combustion.

[0003] The existing internal swirl burner burners on the market have a conical distribution of fire slots or fire holes. The flame produced by combustion is injected inward and rotates in a cone shape. The flame is the highest in the center of the flame and gradually decreases outward, making the flame more concentrated. However, if the internal swirl burner is not well designed (such as an unreasonable structure of the burner or uneven distribution of fire holes), it may lead to insufficient mixing of gas and air, incomplete combustion, and thus produce toxic gases such as carbon monoxide.

[0004] Therefore, this utility model proposes an internal swirl fire aluminum alloy furnace head. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of keyed connections in heavy-duty applications and to provide an internal swirling aluminum alloy furnace head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an internal swirling fire aluminum alloy furnace head, comprising a furnace head body, the top of the furnace head body abutting against an outer ring fire cover, the outer ring fire cover and the outer surface of the furnace head body being fixedly connected in an equidistant array of multiple connecting parts, and the sidewalls of every two corresponding connecting parts being threadedly connected to the same first screw.

[0007] A first air intake cannon is fixedly connected to one side of the outer surface of the burner body, and a second air intake cannon is fixedly connected to the bottom of the burner body. The second air intake cannon is located inside the burner body and is threadedly connected to a center flame cap.

[0008] Furthermore, a large fan blade is fixedly installed on the inner wall of the end of the first air intake cannon away from the burner body, and a first fixing plate is abutted on the upper surface of the first air intake cannon. The first fixing plate and the top side wall of the first air intake cannon are connected by a second screw through a thread.

[0009] Furthermore, a small fan blade is fixedly installed on the inner wall of the end of the second air intake cannon away from the burner body, a second fixing plate is abutted on the upper surface of the second air intake cannon, and another second screw is threadedly connected to the top side wall of the second fixing plate and the second air intake cannon.

[0010] Furthermore, the outer surface of the outer ring fire cap is provided with striped patterns.

[0011] Furthermore, the first air intake barrel has a venturi channel inside, and the diameter shape of the first air intake barrel is multi-level and gradually changes.

[0012] Furthermore, an ignition ceramic needle and a thermocouple are fixedly installed on the side wall of the top of the second air intake barrel, and the ignition ceramic needle and thermocouple are located outside the center fire cap.

[0013] This utility model has the following beneficial effects:

[0014] In use, this utility model's internally rotating aluminum alloy burner head, through the first air intake barrel, the second air intake barrel, the central flame cap, and the outer ring flame cap, and the fixed channel at the burner head's air intake port, ensures that the nozzle is perpendicular and concentric with the burner head's air intake direction. Air entering from both sides of the fixed position mixes with the gas ejected from the nozzle, and after passing through the conical surface of the burner head's air intake channel, the straight position, and the reverse conical surface (Venturi channel), the air and gas are fully mixed before entering the burner head's furnace cavity. Then, through the stepped rotation within the burner head cavity, the mixed gas is ejected through the flame distributor for combustion, ensuring complete combustion and reducing the generation of toxic gases due to imperfect design of the burner head and flame distributor.

[0019] Figures 1 to 2As shown, an internal swirling aluminum alloy burner head is disclosed, comprising a burner head body 3, with an outer ring burner cap 2 abutting the top of the burner head body 3. Multiple connectors 4 are fixedly connected in an equidistant array on the outer surfaces of both the outer ring burner cap 2 and the burner head body 3. The sidewalls of every two corresponding connectors 4 are threaded together by the same first screw 5. That is, a set of connectors 4 is fixed to the outer surfaces of both the outer ring burner cap 2 and the burner head body 3. The two sets of connectors 4 correspond sequentially to each other, and each pair of corresponding connectors 4 in the two sets is locked by the same first screw 5. This fixes the outer ring burner cap 2 to the top of the burner head body 3, preventing it from splitting during transport. The outer surface of the outer ring burner cap 2 is provided with striped patterns 15, which enhances the strength of the outer ring burner cap 2.

[0020] Among them, the main structure of the burner, including the burner body 3, the first air intake barrel 6, and the outer ring fire cover 2, is made of aluminum alloy, which is low-cost, lightweight, and has a delicate surface that is easy to clean.

[0021] Furthermore, the outer ring burner cap 2 is equipped with a rotating oblique groove that is opposite to the air intake direction, which enables the gas to rotate and burn more completely, achieving energy saving, gas saving, higher power, and reduced exhaust emissions.

[0022] The outer surface of the burner body 3 is fixedly connected to a first air intake cannon 6. The first air intake cannon 6 has a venturi channel inside to fully mix the gas and air. The diameter of the first air intake cannon 6 is multi-level and gradually changes. The first air intake cannon 6 has a step-by-step gas transmission to make the gas burn more completely. The bottom of the burner body 3 is fixedly connected to a second air intake cannon 10. The top of the second air intake cannon 10 inside the burner body 3 is threadedly connected to a center burner cap 1.

[0023] A large fan blade 7 is fixedly installed on the inner wall of the first air intake cannon 6 at the end away from the burner body 3. A first fixing plate 8 abuts against the upper surface of the first air intake cannon 6, and a second screw 9 is threaded through and connected to the top side wall of the first air intake cannon 6 and the first fixing plate 8. A small fan blade 11 is fixedly installed on the inner wall of the second air intake cannon 10 at the end away from the burner body 3. A second fixing plate 12 abuts against the upper surface of the second air intake cannon 10, and another second screw 9 is threaded through and connected to the top side wall of the second air intake cannon 10 and the second fixing plate 12. The first fixing plate 8 and the second fixing plate 12 are used to fix the external air intake nozzles, so that the external air source can atomize the liquid or gaseous fuel and spray it into the interior of the first air intake cannon 6 and the second air intake cannon 10, and then into the burner body 3.

[0024] An ignition ceramic needle 13 and a thermocouple 14 are fixedly installed on the side wall of the top of the second air intake barrel 10, respectively. The ignition ceramic needle 13 and the thermocouple 14 are located outside the central burner cap 1. The ignition ceramic needle 13 ignites the gas through an electric spark, ensuring stable combustion. The thermocouple 14, which is the sensing probe (flameout protection needle) of the automatic flameout protection device, is mostly installed near the burner cap and has a diameter of about 5 mm. During normal ignition, the thermocouple generates an electromotive force when heated, which enters the coil of the solenoid valve through a wire. This generates a magnetic field that causes the solenoid valve to engage, thus keeping the gas valve open. If soup or water is accidentally spilled while simmering or boiling, causing an accidental flameout, the voltage of the thermocouple will quickly drop to zero, the solenoid valve coil will lose power, and the gas passage will be quickly cut off to prevent gas leakage (the working principle of the ignition ceramic needle 13 and the thermocouple 14 is common knowledge known to those skilled in the art and will not be elaborated here).

[0025] In actual use of the internal swirling aluminum alloy burner head, external gas enters the burner head body 3 through the first air intake barrel 6 and the second air intake barrel 10, respectively, and is sprayed outward through the central burner cap 1 and the outer ring burner cap 2, respectively. After being ignited by the ignition ceramic needle 13, it burns, with uniform flame and complete combustion, so that the outer and inner rings of the pot are heated evenly. It can achieve higher energy efficiency, lower flue gas, and higher heat load than existing burners, thus achieving the purpose of energy saving and emission reduction.

[0026] Specifically, this burner head is designed with nozzles inserted in the air intake direction. The fixed channel at the burner head's air intake ensures that the nozzles are perpendicular and concentric with the air intake direction. Air enters from both sides of the fixed position and mixes with the gas ejected from the nozzles. After passing through the conical surface of the burner head's air intake channel, the straight position, and the reverse conical surface (Venturi channel), the air and gas are fully mixed before entering the burner head's furnace cavity. Then, through a stepped rotation within the burner head cavity, the mixed gas is ejected through the burner for combustion, ensuring complete combustion and reducing the generation of toxic gases due to imperfect burner and burner design.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
