Description

Technical Field

[0001] This invention relates to the field of aluminum melting industry, specifically to the field of aluminum melting furnaces, and particularly to a gas burner used in the aluminum melting industry. Background Technology

[0002] The regenerative high-temperature air combustion system is a heating technology currently used in crucibleless aluminum melting furnaces. For details, please refer to the appendix. Figure 1 During fuel combustion, the combustion air is guided by a blower into the right-side regenerator chamber and exchanges heat with the regenerator in the right-side regenerator chamber to achieve preheating. Then, the combustion air mixes with the fuel gas and burns at the burner on the right side. The high-temperature flue gas produced by combustion is guided by an induced draft fan through the left-side regenerator chamber and exchanges heat with the regenerator in the left-side regenerator chamber to achieve heat storage. After that, the cooled low-temperature flue gas is discharged through the flue. After a preset time, the reversing valve switches, and the combustion air enters the left-side regenerator chamber and burns at the burner on the left side. The heat of the high-temperature flue gas is stored in the regenerator volume of the right-side regenerator chamber.

[0003] The above describes the working process of a regenerative high-temperature air combustion system. However, it still has some drawbacks, such as: 1. Flame combustion requires constant switching between two burners. During the switch from right-side to left-side combustion, since the flue gas flows out from the left side when the right side is burning, there is initially a lot of flue gas at the left-side combustion position. It takes several seconds for the left flame to ignite before the flue gas can be pushed to the right. In other words, the flue gas will hinder the ignition of the left flame, and at the beginning of left-side combustion, there is a tendency for incomplete combustion. 2. During combustion, simply supplying combustion air and fuel gas to the combustion position results in a relatively poor combustion effect. When using an aluminum melting furnace, the surface of the molten aluminum will oxidize. Therefore, it is necessary to improve the structure of the combustion position to improve combustion completeness, maximize the consumption of oxygen in the combustion air, and reduce the oxidation of the molten aluminum.

[0004] Based on the above, the present invention proposes a gas burner for use in the aluminum smelting industry. Summary of the Invention

[0005] To address the problems mentioned in the background above, the present invention provides a gas burner for use in the aluminum smelting industry.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0007] A gas burner for use in the aluminum melting industry includes a supply component and a combustion component. The combustion component includes a support body on which a combustion head is mounted. The combustion head includes a horizontally arranged, hollow shaft. One end of the connecting shaft extends into the aluminum melting furnace and is provided with a cover, while the other end is connected to the gas inlet pipe of the supply component.

[0008] The upper end of the cover is set in an arc shape with the axis arranged horizontally, and the lower end is set with a narrow outlet. The upper cavity wall of the inner cavity of the cover is provided with an arc plate, which is coaxial with the upper end of the cover. There is a gap between the suspended end of the arc plate and the upper cavity wall of the inner cavity of the cover.

[0009] A heat-conducting plate is provided on the lower arc surface of the arc plate. The bottom of the heat-conducting plate passes through the narrow outlet. There are gaps between the two sides of the heat-conducting plate along the thickness direction and the two hole walls of the narrow outlet along the width direction.

[0010] The outer surface of the intake pipe is provided with a side pipe, and the end of the side pipe is provided with a gas valve. A hollow shaft is coaxially provided inside the connecting shaft. One end of the blade shaft extends into the housing and is provided with rotating blades, and the other end extends out of the side pipe. The side pipe is connected to the blade shaft.

[0011] As a further improvement and optimization of the present invention, the blade shaft is coaxial with the arc plate, the blade shaft can rotate around its own axis, the interior of the rotating blade is hollow and the rotating blade is connected to the blade shaft, and the projection of the rotating blade on the radial direction of the blade shaft increases along the axis of the blade shaft and from the side pipe toward the cover.

[0012] As a further improvement and optimization of the present invention, an igniter is installed on the support body, the ignition end of the igniter extends into the aluminum melting furnace, and multiple rotating blades are arranged in an array along the circumferential direction of the blade axis.

[0013] As a further improvement and optimization of the present invention, an annular groove is provided on the outer circular surface of the blade shaft, and a connecting hole is provided at the bottom of the annular groove. The blade shaft and the side pipe are connected by the cooperation of the annular groove and the connecting hole.

[0014] As a further improvement and optimization of the present invention, the portion of the heat-conducting plate located inside the casing has several through holes.

[0015] As a further improvement and optimization of the present invention, the combustion component also includes a swaying component, which is used to drive the connecting shaft to reciprocate swaying.

[0016] As a further improvement and optimization of the present invention, the yaw assembly includes a motor and a sleeve connected to the connecting shaft. The sleeve is provided with a linkage hole. The output shaft of the motor is parallel to the connecting shaft. The output end of the motor is provided with a yaw rod. The end of the yaw rod is provided with a protruding pin. The protruding pin and the linkage hole form a sliding guide fit along the radial direction of the connecting shaft.

[0017] As a further improvement and optimization of the present invention, the support body is provided with a movable support and a linear module for driving the movable support to move. The moving direction of the movable support is perpendicular to the axis of the connecting shaft, and the motor is provided on the movable support.

[0018] As a further improvement and optimization of the present invention, the supply components include a heat storage chamber, an induced draft fan, and a blower;

[0019] There are two heat storage chambers, each containing a heat storage body. The upper end of the heat storage chamber has an upper pipe, and the lower end has a lower pipe.

[0020] The induced draft fan is equipped with a flue pipe at its inlet end, and the end of the flue pipe extends into the aluminum melting furnace. The induced draft fan is also equipped with a connecting pipe at its outlet end.

[0021] The blower has a connecting pipe 2 at the air inlet and a connecting pipe 3 at the air outlet. The end of the connecting pipe 3 is connected to the air inlet pipe.

[0022] The connection between connecting pipe 1, connecting pipe 2, and the upper pipes of the two heat storage chambers is achieved through a reversing valve.

[0023] As a further improvement and optimization of the present invention, the reversing valve includes a state one and a state two, and the two heat storage chambers are named heat storage chamber one and heat storage chamber two, respectively. When the reversing valve is in state one, heat storage chamber one is connected to connecting pipe one, and heat storage chamber two is connected to connecting pipe two. When the reversing valve is in state two, heat storage chamber one is connected to connecting pipe two, and heat storage chamber two is connected to connecting pipe one.

[0024] Compared with the prior art, the beneficial effects of this invention are as follows:

[0025] One of the core aspects of this solution is that when the reversing valve switches states, the overall path of the high-temperature flue gas discharged from the aluminum melting furnace remains unchanged: exhaust pipe, induced draft fan, connecting pipe 1, and reversing valve. Therefore, the discharge of high-temperature flue gas is relatively smooth and does not affect the flame combustion.

[0026] Another core aspect of this solution lies in the combustion components: 1. Since the projection of the rotating blades on the radial direction of the blade axis increases along the blade axis centerline and from the connecting hole towards the casing, based on the principle of centrifugal force, the centrifugal force also gradually increases along the direction of the increasing projection of the rotating blades. Therefore, there is a negative pressure traction force within the blade axis, which pulls the gas to gradually flow away from the connecting shaft, so that the gas can flow out from any position at the opening of the rotating blades. Furthermore, since the width of the opening of the rotating blades is small and the length is large, the gas can flow into the casing evenly in the form of a thin air curtain, collide and mix with the combustion air, and achieve a rapid, thorough and uniform mixing effect between the two.

[0027] 2. When the mixture of combustion air and fuel gas flows out through gap two, due to the small width of gap two, the mixture flowing out through gap two forms a thin gas film. The advantages are twofold: firstly, the thin gas film has a closer contact with the heat-conducting plate, and the heat-conducting plate is scorched by the flame, so the mixture in the thin gas film state can be fully combusted; secondly, based on Bernoulli's principle, the gas in the aluminum melting furnace tends to move closer to the heat-conducting plate. This tendency can prevent the mixture from escaping and causing incomplete combustion, and it can also make the surrounding oxygen move closer to the flame, providing combustion support for the flame. This not only further improves the completeness of combustion, but also maximizes the consumption of oxygen in the aluminum melting furnace, reducing the oxidation of the aluminum solution.

Detailed Implementation

[0040] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0041] Reference Figures 2-10 A gas burner for use in the aluminum smelting industry includes a supply component 100 and a combustion component 200.

[0042] I. Combustion components 200:

[0043] It should be noted that in the schematic diagram shown in the attached drawings of this scheme, the flame of the combustion burner 204 of the combustion component 200 is pointing upwards, but it is actually burning the aluminum material in the aluminum melting furnace downwards. It is just a different display angle. The aluminum melting furnace is not shown in the figure.

[0044] Reference Figures 6-10 The combustion component 200 includes a support body 201, on which an igniter 203 and a combustion burner head 204 are installed, wherein the ignition end of the igniter 203 extends into the aluminum melting furnace.

[0045] Reference Figure 8 and Figure 10 The combustion burner 204 includes a horizontally arranged, hollow shaft. One end of the shaft extends into the aluminum melting furnace and is provided with a cover 2041, while the other end is connected to the air inlet pipe 110 of the supply component 100.

[0046] The upper end of the cover 2041 is configured as an arc shape with the axis arranged horizontally, and the lower end is provided with a narrow outlet. The upper cavity wall of the inner cavity of the cover 2041 is provided with an arc plate 2042, which is coaxial with the upper end of the cover 2041. There is a gap between the suspended end of the arc plate 2042 and the upper cavity wall of the inner cavity of the cover 2041.

[0047] A heat-conducting plate 2043 is provided on the lower arc surface of the arc plate 2042. The bottom of the heat-conducting plate 2043 passes through the narrow outlet. There are gaps between the two sides of the heat-conducting plate 2043 along the thickness direction and the two hole walls of the narrow outlet along the width direction. The part of the heat-conducting plate 2043 located inside the cover 2041 is provided with several through holes 2044.

[0048] Reference Figures 8-10 The burner head 204 also includes a gas assembly 205. Specifically, the outer surface of the gas inlet pipe 110 is provided with a side pipe 111, and the end of the side pipe 111 is provided with a gas valve 112. The gas assembly 205 includes a blade shaft 2052 coaxially disposed in the connecting shaft. One end of the blade shaft 2052 extends into the cover 2041 and is provided with a rotating blade 2051, and the other end extends out of the side pipe 111.

[0049] The blade shaft 2052 is coaxial with the arc plate 2042. The blade shaft 2052 can rotate around its own axis. The outer circular surface of the blade shaft 2052 is provided with an annular groove. A connecting hole 2053 is opened at the bottom of the annular groove. Through the cooperation of the annular groove and the connecting hole 2053, the blade shaft 2052 is connected to the side pipe 111. In addition, the blade shaft 2052 is a hollow shaft and is sealed at both ends.

[0050] The rotating blade 2051 is hollow inside and is connected to the blade shaft 2052. Multiple rotating blades 2051 are arranged in an array along the circumferential direction of the blade shaft 2052. The projection of the rotating blade 2051 on the radial direction of the blade shaft 2052 increases along the axis of the blade shaft 2052 and from the connecting hole 2053 to the cover 2041.

[0051] Working process of combustion component 200:

[0052] Combustion air is drawn into the housing 2041 through the intake pipe 110 and connecting shaft by the supply component 100. Simultaneously, combustion gas flows into the rotating blade 2051 through the gas valve 112, annular groove, connecting hole 2053, and connecting shaft. The rotating blade 2051 rotates, and under centrifugal force, throws the combustion gas into the housing 2041. The combustion gas and combustion air collide and mix, then flow out through gap one and gap two, and are ignited by the igniter 203. The advantages of this method are:

[0053] 1. Since the projection of the rotating blade 2051 on the radial direction of the blade shaft 2052 increases along the axis of the blade shaft 2052 and from the connecting hole 2053 toward the cover 2041, based on the principle of centrifugal force, the centrifugal force also gradually increases along the direction of the increasing projection of the rotating blade 2051. Therefore, there is a negative pressure traction force in the blade shaft 2052, which pulls the gas to flow gradually away from the connecting shaft, so that the gas can flow out from any position at the opening of the rotating blade 2051. Since the opening of the rotating blade 2051 is small in width and large in length, the gas can flow into the cover 2041 evenly in the form of a thin air curtain, and collide and mix with the combustion air to achieve a rapid, full and uniform mixing effect.

[0054] 2. When the mixture of combustion air and fuel gas flows out through gap two, due to the small width of gap two, the mixture flowing out through gap two is in a thin gas film state. The advantages are as follows: on the one hand, the thin gas film has a closer contact with the heat-conducting plate 2043, and the heat-conducting plate 2043 is scorched by the flame. Therefore, the mixture in the thin gas film state can be fully combusted. On the other hand, based on Bernoulli's principle, the gas in the aluminum melting furnace has a tendency to move closer to the heat-conducting plate 2043. This tendency can prevent the mixture from escaping and causing incomplete combustion, and can also make the surrounding oxygen move closer to the flame, providing combustion support for the flame. This not only further improves the completeness of combustion, but also maximizes the consumption of oxygen in the aluminum melting furnace and reduces the oxidation of the aluminum solution.

[0055] In a preferred embodiment, to ensure more thorough and uniform contact between the flame of the combustion burner 204 and the aluminum material in the aluminum melting furnace, thereby improving the smelting effect, refer to... Figure 6 and Figure 7 The combustion component 200 also includes a swaying component 202, which drives the connecting shaft to sway back and forth, thereby causing the flame to sway. On the one hand, this makes the flame contact the aluminum material more evenly, and on the other hand, it changes the position of the combustion burner head 204, so as to maximize the consumption of oxygen in the aluminum melting furnace and enhance the effect of reducing the oxidation of the aluminum solution.

[0056] Specifically, the yaw assembly 202 includes a motor 2023 and a sleeve 2021 connected to the connecting shaft. The sleeve 2021 is provided with a linkage hole 2022. The output shaft of the motor 2023 is parallel to the connecting shaft. A yaw rod 2024 is provided at the output end of the motor 2023. A protruding pin 2025 is provided at the end of the yaw rod 2024. The protruding pin 2025 and the linkage hole 2022 form a sliding guide fit along the radial direction of the connecting shaft. The motor 2023 drives the yaw rod 2024 to rotate. During the rotation, the sleeve 2021 is driven to reciprocate around the connecting shaft through the fit between the protruding pin 2025 and the linkage hole 2022. The sleeve 2021 yaws together with the connecting shaft.

[0057] Furthermore, the support body 201 is provided with a movable support 2027 and a linear module 2026 for driving the movable support 2027 to move. The moving direction of the movable support 2027 is perpendicular to the axis of the connecting shaft. The linear module 2026 can adopt existing electric telescopic rod technology or existing lead screw linear motion technology, etc., which will not be elaborated. The motor 2023 is set on the movable support 2027. The advantage is that by changing the position of the motor 2023, the initial position of the protrusion 2025 on the linkage hole 2022 is changed, thereby adjusting the sway amplitude.

[0058] II. Supply of 100 components:

[0059] Reference Figures 2-6 The supply component 100 includes a heat storage chamber 102, a reversing valve 101, an induced draft fan 105, and a blower 108. The latter three are all achievable with existing technology and will not be described in detail.

[0060] There are two heat storage chambers 102. A heat storage body is installed in the heat storage chamber 102. An upper pipe 103 is installed at the upper end of the heat storage chamber 102 and a lower pipe is installed at the lower end.

[0061] The induced draft fan 105 is equipped with a flue pipe 106 at its air inlet end, and the end of the flue pipe 106 extends into the aluminum melting furnace. The induced draft fan 105 is equipped with a connecting pipe 104 at its air outlet end.

[0062] The blower 108 has a connecting pipe 2 107 at the air inlet end and a connecting pipe 3 109 at the air outlet end. The end of the connecting pipe 3 109 is connected to the air inlet pipe 110.

[0063] The connection between the first connecting pipe 104, the second connecting pipe 107, and the upper pipes 103 of the two heat storage chambers 102 is achieved through a reversing valve 101. The reversing valve 101 has two states: state one and state two. For ease of description, the two heat storage chambers 102 are named heat storage chamber one and heat storage chamber two, respectively. When in state one, heat storage chamber one is connected to the first connecting pipe 104, and heat storage chamber two is connected to the second connecting pipe 107. When in state two, heat storage chamber one is connected to the second connecting pipe 107, and heat storage chamber two is connected to the first connecting pipe 104.

[0064] In addition, the input end of the blade shaft 2052 can be connected to the output shaft of the blower 108, or a separate motor can be provided to drive the blade shaft 2052 to rotate.

[0065] The working process of supplying component 100:

[0066] by Figure 4 Taking a specific perspective, heat storage chamber one is located on the right side, and heat storage chamber two is located on the left side;

[0067] The induced draft fan 105 and the blower 108 start simultaneously, and the reversing valve 101 is in state one. The combustion air flows into the combustion component 200 through the heat storage chamber two, the reversing valve 101, the connecting pipe two 107, the blower 108, the connecting pipe three 109, and the air intake pipe 110 in sequence. At the same time, the high-temperature flue gas generated by combustion is discharged outward through the exhaust pipe 106, the induced draft fan 105, the connecting pipe one 104, the reversing valve 101, and the heat storage chamber one in sequence.

[0068] After a preset time, the reversing valve 101 switches to state two. At this time, the combustion air flows into the combustion component 200 through the heat storage chamber one, the reversing valve 101, the connecting pipe two 107, the blower 108, the connecting pipe three 109, and the air intake pipe 110 in sequence. The high-temperature flue gas is discharged outward through the exhaust pipe 106, the induced draft fan 105, the connecting pipe one 104, the reversing valve 101, and the heat storage chamber two in sequence.

[0069] The advantage of repeating this process is that:

[0070] When the reversing valve 101 switches states, the overall path of the high-temperature flue gas discharged from the aluminum melting furnace remains unchanged, which is always through the exhaust pipe 106, the induced draft fan 105, the connecting pipe 104, and the reversing valve 101. Therefore, the discharge of the high-temperature flue gas is relatively smooth and does not affect the flame combustion, thus solving the problem 1 mentioned in the background art.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
