Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of burners, in particular to a high-heat-efficiency gas burner for frying furnaces. BACKGROUND

[0002] As a kind of combustion equipment, frying pan burners have various types, which can be divided into fuel oil (such as diesel oil), gas (such as natural gas, liquefied gas) burners, etc. according to fuel, among which the gas type as the current mainstream burner is suitable for commercial kitchens (such as restaurants, hotels), food processing plants, etc. Especially for restaurants, hotels and other commercial places, in order to speed up the meal serving speed, a burner with larger firepower is usually selected, which requires more gas, and is equipped with a blower and other equipment to provide more air at the same time, so the heat efficiency of the burner is required to be higher.

[0003] For example, a low-nitrogen burner based on flue gas internal circulation is disclosed in Chinese Patent No. CN114593419A. This type of burner has two paths for sending gas to the furnace interior, and air is also sent to the furnace interior through two paths. The gas and air sent to the gas inner cavity and air outer cavity, respectively, are mixed and then reach the furnace, which improves the combustion efficiency of the burner.

[0004] However, in the existing form of the burner, the gas jet drives air to be mixed together. Since the size of the air path is usually fixed, the gas jet size changes to adjust the flame size, and the air in the air path always maintains a fixed opening size (although the air is passively sucked into the gas, the size of the air path opening is also an important factor affecting air intake), which causes the mixture of gas and air to be uneven, resulting in an imbalance in the mixture of gas and air, which causes incomplete combustion. SUMMARY

[0012] Further, the second driving shaft extends into the premixing chamber, and can generate driving force for discharging the mixed gas and air in response to the rotation driving of the fourth impeller and the downward driving of the armature ring.

[0013] Further, the first impeller is rotatably installed inside the air chamber, and can rotate in response to the air jet pushing and form an air passage for air flow on the blade side of the first impeller; the second guide ring is arranged on the blade of the fourth impeller, and the second guide ring and the fourth impeller, the first guide ring and the second impeller form a gas passage for gas flow.

[0014] Further, the outer combustion ring is located at the edge of the burner head and forms a second gas supply cavity with the burner head; and the inner combustion ring is located at the center of the burner head and forms a first gas supply cavity with the burner head.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. Figures 1-33 The present application proposes a gas burner for frying furnace with high thermal efficiency.

[0026] Embodiment one: as shown in Figures 1-4 , Figure 11 , Figure 17 The gas burner for frying furnace with high thermal efficiency comprises a furnace head 1, a furnace jacket 2 arranged below the furnace head 1, a gas force passage formed between the furnace jacket 2 and the furnace head 1, and a premixing chamber formed at the top of the gas force passage. A gas chamber 13 is arranged at the bottom of the gas force passage, and a gas passage 21 is formed circumferentially (as shown in Figure 11As shown), an air chamber 12 is provided above the gas chamber 13, and an air passage 24 is provided circumferentially (as shown). Figure 17 As shown), the gas in the gas chamber 13 is ejected through the gas passage 21. During the ejection process, the gas in the air passage 24 is entrained, so that the gas and air flow together into the premixing chamber.

[0027] Furthermore, an annular valve plate is provided above the gas passage 21. The annular valve plate can close the air passage 24 in a normally closed state. At the same time, a pressure component is provided below the annular valve plate. The pressure component can generate a drive in response to the release pressure of the gas itself, and control the opening size of the annular valve plate to the air passage 24, so that the gas and air are mixed quantitatively in a spiral state. After mixing, it is delivered to the premixing chamber for further mixing. After being fully mixed, the gas is selectively delivered to the inner and outer rings of the burner head 1 in response to the pressure and flow rate of the gas itself, so that the combustion size of the burner head 1 is synchronized with the gas supply size.

[0028] like Figures 8-16As shown, to enable the annular valve plate to open the air passage 24, the pressure assembly includes a piston 16 located inside the gas chamber 13. A second impeller 15 is rotatably mounted on the piston 16. Simultaneously, a gas valve pipe 4 is provided on the gas chamber 13 (the gas valve pipe 4 is tangentially aligned with the blades of the second impeller 15, so that the gas delivered by the gas valve pipe 4 can drive the second impeller 15 to rotate under its own pressure impact). First guide rings 20 are interlaced on the blades of the second impeller 15, so that the gap between the first guide rings 20 and the second impeller 15 forms a gas passage 21 (the bottom inlet of the gas passage 21 has a narrow opening structure, ensuring that the gas pressure flow rate is always greater than the narrow opening output flow rate; the top of the gas passage 21 has a spiral structure, allowing the gas to flow along the spiral structure during output, tending towards a spiral state, and utilizing the rotation of the second impeller 15 itself to maintain a spiral jet state when the gas jet is ejected). The first guide rings 20 are fixedly connected to the first annular valve plate 25, and the gas is controlled by a switch. When the valve of valve pipe 4 is open or closed, the gas is delivered to the gas chamber 13 under pressure. Since the gas pressure and flow rate are always greater than the output flow rate of gas passage 21, the gas is slowly accumulated in the gas chamber 13 while being jetted out, putting pressure on piston 16 and pushing piston 16 downward. As the opening and closing of the valve of gas valve pipe 4 gradually increases, the gas pressure and flow rate increase, and the output flow rate of gas through gas passage 21 increases synchronously. At this time, the pressure acting on piston 16 also increases synchronously, pushing piston 16 further downward. During the downward movement of piston 16, the first annular valve plate 25 is continuously moved away from the air passage 24, so that the air passage 24 maintains a larger opening state as the gas pressure and flow rate increase. This allows the jetted gas to entrain more air from the air passage 24, so that the air passage 24 can maintain a dynamic opening size according to the size of the gas jet, achieving a mixing balance between gas and air under dynamic changes and improving the completeness of gas combustion.

[0029] Furthermore, the pressure assembly also includes a second magnetic ring 23 located below the piston 16, and a first magnetic ring 22 (e.g., below the second magnetic ring 23) is provided below the first magnetic ring 22. Figures 15-16 As shown), the first magnetic ring 22 and the second magnetic ring 23 repel each other, forming a deformation space, which provides downward displacement for the piston 16 when it is subjected to force. The magnetic repulsion between the first magnetic ring 22 and the second magnetic ring 23 provides magnetic support for the piston 16, so that the piston 16 gradually overcomes the magnetic force and moves downward when subjected to changes in the gas pressure (the gas inlet pressure of burners used in restaurants, hotels and other places is generally between 3000 and 5000 Pa. The conversion of its force is intuitively reflected as equivalent to a 3 to 5 kg object pressing on an area the size of a palm. The pressure area of ​​the piston 16 in the gas chamber 13 is similar to the size of a palm. Therefore, the piston 16 can overcome the magnetic force between the two sets of magnetic rings and move downward when subjected to force).

[0030] It should be noted that a first fixed ring 18 and a first movable ring 17 are respectively provided on the outer rings of the first magnetic ring 22 and the second magnetic ring 23 to limit and fix the two sets of magnetic rings. Furthermore, the first fixed ring 18 and the first movable ring 17 also maintain relative sliding to provide limiting guidance when the piston 16 moves under force.

[0031] like Figures 8-9 , Figures 17-20 As shown, to achieve the mixing of gas and air, a first impeller 14 is rotatably installed inside the air chamber 12, and an air inlet pipe 3 is provided on one side of the air chamber 12 (the air inlet pipe 3 is tangentially aligned with the first impeller 14, so that when external equipment such as a blower delivers air into the air chamber 12 through the air inlet pipe 3, the resulting airflow can drive the first impeller 14 to rotate). One side of the blades of the first impeller 14 forms an air passage 24 for airflow, so that when the gas jets out spirally from the gas passage 21 in response to the rotation of the second impeller 15, the air can synchronously respond to the rotation of the first impeller 14, spiraling along the air passage 24. Then, under the entrainment of the gas jet, the gas and air are mixed in a spiral state to improve mixing efficiency (e.g., Figures 18-20 (As shown).

[0032] It should be noted that the pressure assembly also includes a first drive shaft 11 located in the middle of the second impeller 15. The first drive shaft 11 extends into the premixing chamber and can rotate synchronously in response to the rotation of the second impeller 15. Furthermore, the first drive shaft 11 is connected to a third impeller 19 located in the premixing chamber. This allows the third impeller 19, driven by the first drive shaft 11, to further turbulently mix the gas and air when they are delivered to the premixing chamber after being combined, so that the two are fully combined (e.g., Figures 8-9 (As shown).

[0033] like Figures 3-7As shown, to achieve synchronous emission of the mixed fuel gas and air, an outer combustion ring 5 is provided along the edge of the burner head 1, forming a second air supply chamber 8 between the outer ring and the burner head 1. An inner combustion ring 6 is provided at the center of the burner head 1, forming a first air supply chamber 7 between the inner ring and the burner head 1. Simultaneously, a top cover 9 is provided on the inner ring of the third impeller 19, located at the air inlet of the first air supply chamber 7. A sealing ring 10 is provided on the outer ring of the third impeller 19, located at the air inlet of the second air supply chamber 8. When the third impeller 19 is driven by the rotation of the first drive shaft 11, it can also move downward in response to the downward movement of the first drive shaft 11, causing the combination of the top cover 9 and the sealing ring 10 to move downward synchronously. When the gas delivery pressure and flow rate are small, the piston 16 moves downward a small amount, which in turn causes the first drive shaft 11 to move downward slightly, removing the top cover 9 from the first gas supply chamber 7. This allows the mixed gas and air to be delivered to the inner combustion ring 6 through the first gas supply chamber 7, providing the gas required for small-fire combustion (at this time, the upper end of the sealing ring 10 can continuously seal the second gas supply chamber 8). Furthermore, when the gas delivery pressure and flow rate are large, the piston 16 moves downward more, and the first drive shaft 11 moves downward more, so that while the top cover 9 continues to move away from the first gas supply chamber 7, the sealing ring 10 can move away from the second gas supply chamber 8 synchronously. This allows the mixed gas and air to be distributed along the second gas supply chamber 8 to the outer combustion ring 5, providing the gas required for large-fire combustion, so that the size of the combustion at the burner head 1 is synchronized with the size of the gas supply.

[0034] During use (operation), the valve size of the gas valve pipe 4 is controlled by a switch, allowing gas to be delivered into the gas chamber 13 under pressure. When the gas is delivered into the gas chamber 13, because the gas pressure and flow rate are always greater than the output flow rate of the gas passage 21, the gas is jetted out while simultaneously accumulating slowly within the gas chamber 13. This exerts pressure on the piston 16, pushing it downwards and generating a driving force that moves the first annular valve plate 25 downwards. This causes the first annular valve plate 25 to move away from the air passage 24, thus opening the air passage 24. When the gas is turned on, the gas supply can drive the second impeller 15 to rotate, causing the gas to move in a spiral state. At this time, external blowers and other equipment simultaneously deliver air to the air chamber 12 through the air inlet pipe 3. The air force generated by the air can drive the first impeller 14 to rotate, so that when the gas is spirally ejected from the gas passage 21 in response to the rotation of the second impeller 15, the air can synchronously respond to the rotation of the first impeller 14 and spirally rotate along the air passage 24. Then, under the entrainment of the gas jet, the gas and air are mixed in a spiral state. While the second impeller 15 rotates and moves downward, the first drive shaft 11 rotates and moves downward synchronously, which drives the third impeller 19 to rotate and the top cover 9 and sealing ring 10 to move downward synchronously. The rotation of the third impeller 19 mixes the gas and air again. The top cover 9 and sealing ring 10 open sequentially to selectively deliver the mixed gas to the first gas supply chamber 7 and the second gas supply chamber 8, so that the size of the combustion is synchronized with the size of the gas supply and the size of the combustion flame is controlled synchronously.

[0035] Example 2, as Figures 21-33 As shown, this embodiment differs from Embodiment 1 in that its pressure assembly includes a fourth impeller 42 rotatably mounted inside the gas chamber 13. The fourth impeller 42 rotates in response to the impact of the gas jet, and a second guide ring 43 is provided on the blades of the fourth impeller 42, forming a gas passage 21 between the second guide ring 43 and the fourth impeller 42. After the gas drives the fourth impeller 42 to rotate, it spirally jets out along the gas passage 21. At the same time, a second drive shaft 26 is slidably engaged in the middle of the fourth impeller 42. The second drive shaft 26 can rotate synchronously in response to the rotation of the fourth impeller 42 and generate an axial movement driving force, which drives the second annular valve plate 39 mounted on the second drive shaft 26 to move downward. By utilizing the change of the pressure and flow rate of the gas itself, the second annular valve plate 39 controls the synchronous opening of the air passage 24, so that the gas spirally jetted out is drawn in with the air in the spiral flow state for quantitative mixing.

[0036] It should be noted that, as Figures 32-33 As shown, the inner ring of the second annular valve plate 39 is provided with a support ring 38, and the support ring 38 is rotatably connected to the first limiting ring 31 provided on the second drive shaft 26, so that the second annular valve plate 39 is only subjected to the downward pressure of the second drive shaft 26 and does not rotate synchronously with the second drive shaft 26, thereby reducing the overall self-weight and rotational load drive of the second drive shaft 26. Furthermore, the outer ring of the second annular valve plate 39 is provided with a limiting slip 40, and the inner ring of the first impeller 14 is provided with a limiting groove 41. By utilizing the sliding combination of the limiting slip 40 and the limiting groove 41, the second annular valve plate 39 is slidably installed on the first impeller 14, providing a guide limit for the downward movement of the second annular valve plate 39.

[0037] In addition, a first long gear 32 is provided on the second drive shaft 26, and a first internal gear ring 35 is provided on the fourth impeller 42. The first long gear 32 can slide and mesh along the first internal gear ring 35 to realize the rotation and movement of the second drive shaft 26 along the fourth impeller 42.

[0038] As a further solution to this embodiment, such as Figures 27-31As shown, to achieve synchronous downward movement during the rotation of the second drive shaft 26, the pressure assembly also includes a power generation coil 30 located at the bottom of the second drive shaft 26, and an electromagnet 36 located above the power generation coil 30. The electromagnet 36 is positioned opposite to the armature ring 37 rotatably mounted on the second drive shaft 26, so that when the second drive shaft 26 rotates, the power generation coil 30 generates electricity in response to the rotation of the second drive shaft 26. When the electromagnet 36 is energized, a magnetic force is generated, causing the armature ring 37 to move closer to the electromagnet 36. Simultaneously, this movement generates a driving force that propels the second drive shaft 26 downward. Then, by moving the second drive shaft 26 downward, the second annular valve plate 39 is moved downward, opening the air passage 24. As the pressure and flow rate of the gas change, the rotational push of the fourth impeller 42 also changes, causing the power acting on the generator coil 30 when the second drive shaft 26 rotates to change. This changes the magnetic attraction force of the electromagnet 36, dynamically driving the downward movement of the second drive shaft 26. As a result, the second annular valve plate 39 controls the opening size of the air passage 24 according to the pressure and flow rate of the gas, so that the gas and air are kept in a metered mixture.

[0039] It should be noted that, as Figures 27-29 As shown, the power generation coil 30 consists of a housing 301, a turntable 302, a magnet ring 303, a second internal gear ring 304, and an induction coil 305. The induction coil 305 is located inside the housing 301, and the magnet ring 303 is located inside the turntable 302. The second internal gear ring 304 is located in the middle of the turntable 302 and maintains a sliding engagement with the second long gear 34 located on the second drive shaft 26 (the sliding engagement between the second long gear 34 and the second internal gear ring 304 allows the second drive shaft 26 to slide and rotate on the turntable 302). When the second drive shaft 26 rotates, it drives the turntable 302 to rotate, causing the magnet ring 303 to rotate relative to the induction coil 305. The magnetic field of the magnet ring 303 cuts the induction coil 305 as the turntable 302 rotates, generating an alternating induced electromotive force. The induced electromotive force forms an alternating current through the induction coil 305 and is output to the electromagnet 36, causing the electromagnet 36 to generate an electromagnetic attraction force.

[0040] And, as Figures 30-31As shown, a combination of a second movable ring 27 and a second fixed ring 28 is provided below the gas chamber 13, and a strain spring 29 is provided between the second movable ring 27 and the second fixed ring 28. An electromagnet 36 is provided on the second fixed ring 28, and an armature ring 37 is provided on the second movable ring 27 and is rotatably connected to the second limiting ring 33 provided on the second drive shaft 26. This allows the armature ring 37 to only apply downward pressure to the second drive shaft 26 and not to rotate synchronously with the second drive shaft 26, thereby reducing the overall self-weight and rotational load drive of the second drive shaft 26. At the same time, the combination of the second movable ring 27 and the second fixed ring 28 can guide and limit the movement of the armature ring 37 by magnetic force. The strain spring 29 provided between the second movable ring 27 and the second fixed ring 28 can provide self-resetting after the armature ring 37 moves, so that when the gas supply stops, it pushes the second drive shaft 26 to reset.

[0041] Furthermore, the second drive shaft 26 extends into the premixing chamber and is connected to the combination of the third impeller 19, the top cover 9, and the sealing ring 10. The second drive shaft 26 responds to the rotation of the fourth impeller 42 to generate a driving force that drives the third impeller 19 to rotate, thus fully mixing the gas and air. In response to the downward movement of the magnetic attraction, the second drive shaft 26 generates a driving force that drives the top cover 9 and the sealing ring 10 to open, thus delivering the mixed gas and air into the burner head 1 for combustion.

[0042] Unlike Embodiment 1, in use (operation), when the gas is delivered into the gas chamber 13, it drives the fourth impeller 42 to rotate. The rotation of the fourth impeller 42 drives the second drive shaft 26 to rotate. During the rotation of the second drive shaft 26, the generator coil 30 generates electricity, which energizes the electromagnet 36. This generates a magnetic attraction force that moves the armature ring 37 toward the electromagnet 36. At the same time, this movement generates a driving force that drives the second drive shaft 26 to move downward. Then, the downward movement of the second drive shaft 26 drives the second annular valve plate 39 to move downward, opening the air passage 24 so that the gas and air are kept in a metered spiral mixture.

[0043] Furthermore, the rotation and downward movement of the second drive shaft 26 simultaneously acts on the third impeller 19, the top cover 9, and the sealing ring 10, thereby achieving the remixing of gas and air, as well as the synchronous change of the gas supply and combustion intensity.
