Description

Technical Field

[0001] This invention relates to the field of burner technology, specifically to a dual-nozzle omnidirectional burner for a suspension kiln. Background Technology

[0002] A burner is a general term for a device that sprays fuel and air out in a certain way to mix and burn. Burners are classified into several types according to their application fields, such as industrial burners, combustion engines, civil burners, and special burners. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium. A suspension kiln is a vertical structure in which materials are suspended in the kiln by airflow and sintered using high-temperature airflow. Currently, the fuel spraying of the burners in existing suspension kilns is not uniform or comprehensive enough across the cross section, which cannot guarantee sufficient contact with the material and results in low thermal utilization efficiency. As a result, it takes a long time to sinter the material into the required state. Moreover, the burner nozzles are mostly of a single structure, which makes the combustion incomplete. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-nozzle omnidirectional burner for suspension kilns, addressing the problems mentioned in the background art. These problems include uneven and incomplete fuel spraying across the cross-section of existing suspension kilns, resulting in insufficient contact with the material, low thermal efficiency, and the need for extended periods to sinter the material to the desired state. Furthermore, the burner nozzles are often of a single structure, leading to incomplete combustion. This device, through two sets of combustion aid channels and fuel channels, as well as multiple sets of external and internal nozzles at different positions, enables more precise flame control. This not only improves sintering efficiency but also fuel combustion efficiency. It can also be adjusted according to different production processes, expanding its application range and reducing limitations. Simultaneously, it enhances user safety. Higher combustion efficiency and omnidirectional combustion not only improve the sintering quality of the material but also reduce the user's production costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dual-nozzle omnidirectional burner for a suspension kiln, comprising a suspension kiln body, wherein two sets of combustion-supporting channels are arranged inside the suspension kiln body, and fuel channels are installed inside the combustion-supporting channels.

A compensation mechanism for improving combustion efficiency is provided inside the pressure stabilizing mechanism.

[0005] Preferably, one end of the first outer tube is connected to a second outer tube, and the inside of the second outer tube is installed with a second inner tube connected to the first inner tube, which facilitates the addition of fuel and combustion-supporting gas to the device. One set of the outer nozzles is located at the bottom of the combustion-supporting channel, and three sets of the outer nozzles are located on the surface of the combustion-supporting channel that are close to each other. The three sets of outer nozzles are staggered to ensure that the fuel is sprayed evenly on the cross-section without dead corners, ensuring full contact with the material and enabling more comprehensive combustion. The inside of the inner nozzle is fixedly connected with a heat insulation cover for protecting the gear, gear ring, push block and electric push rod, to avoid damage to them by high temperature and to improve their service life.

[0006] Preferably, the adjusting plate is movable inside the adjusting groove, and the movable angle is ±5 degrees, which makes it convenient for the user to adjust the angle of the adjusting plate and control the thickness and length of the flame according to the production process.

[0007] Preferably, the control end of the electric push rod is electrically connected to an external power source via an external switch, which facilitates user control of the device.

[0008] Preferably, the pressure stabilizing mechanism includes a flow stabilizing box, one end of the first outer tube is connected to the flow stabilizing box, and a pressure stabilizing box connected to the first inner tube is fixedly connected inside the flow stabilizing box. Both the flow stabilizing box and the pressure stabilizing box are equipped with a first pressure sensor. The control terminal of the first pressure sensor is electrically connected to an external power supply through an external switch, which facilitates the user to detect the real-time pressure of fuel and combustion-supporting gas.

[0009] Preferably, a control box is fixedly connected inside the pressure stabilizing box. An L-shaped flow limiting plate is connected inside the control box via a bearing, and one side of the flow limiting plate is in contact with one end of the first inner tube to control the fuel input speed. A spring fixed to the inner wall of the control box is uniformly fixed to one end of the flow limiting plate. A stop plate is attached to one side of the flow limiting plate, and a threaded rotating rod connected to the control box via a bearing is connected to one side of the stop plate via a threaded connection. One end of the threaded rotating rod extends to the outside of the pressure stabilizing box. Two sets of guide sleeves located on both sides of the threaded rotating rod are fixedly connected to the inner wall of the control box. One end of the guide sleeve is slidably connected to a guide rod fixedly connected to the stop plate, which facilitates the user to control the fuel feed rate and also enables unidirectional fuel flow, improving the safety of the device.

[0010] Preferably, the compensation mechanism includes a replenishment box. The bottom end of the pressure stabilizing box is fixedly connected to a replenishment box that fits against the flow stabilizing box. The inner wall of the bottom end of the pressure stabilizing box is evenly provided with replenishment channels communicating with the replenishment box. One-way valves are installed at the top of each replenishment channel. The inside of the replenishment box is provided with a sealing plate for sealing the replenishment channels. The bottom end of the sealing plate is slidably connected to two sets of slide rails fixedly connected to the inner wall of the replenishment box. The middle part of the sealing plate is threadedly connected to a threaded rod connected to the replenishment box through a bearing. A motor is installed at one end of the replenishment box, and the output end of the motor is fixedly connected to the threaded rod. Replenishment air pumps are installed on both sides of the replenishment box. A second pressure sensor is installed on the inner wall of one side of the replenishment box, which allows the user to premix the combustion-supporting gas and fuel according to the production process requirements, thereby improving the combustion efficiency of the fuel.

[0011] Preferably, the control terminals of the motor, the supplementary air pump, and the second pressure sensor are all electrically connected to an external power source via an external switch, which facilitates user control of the device.

[0012] Preferably, the replenishment channel and the one-way valve are arranged in a matrix, which facilitates the user to accurately control the amount and speed of the gas supply.

[0013] Compared with the prior art, the beneficial effects of the present invention are: Before using this device, the user should configure it according to the production process, setting the fuel intake volume. Rotating the threaded rod controls the movement of the stop plate. When the stop plate moves away from the flow-limiting plate, the fuel intake volume increases until it reaches the set feed volume. When fuel is supplied, the fuel pressure pushes open the flow-limiting plate. When fuel is shut off, a spring quickly cuts off the fuel passage, and rotating the threaded rod completely cuts it off, improving the safety of the device. During use, the user can detect the fuel pressure inside the pressure stabilizing tank and the combustion-supporting gas pressure inside the flow-stabilizing tank using the first pressure sensor. This allows for real-time monitoring of the fuel and combustion-supporting gas pressures during operation, further enhancing user safety. The system ensures complete combustion efficiency by allowing users to control the amount of auxiliary combustion gas added according to their production process. This premixing of fuel and auxiliary combustion gas improves combustion efficiency. Based on a set content, the motor operates, and a threaded rod moves the sealing plate, preventing it from sealing the replenishment channel. A second pressure sensor detects the pressure of the auxiliary combustion gas inside the replenishment tank. A replenishment gas pump then adds auxiliary combustion gas from the flow stabilization tank to the replenishment tank, maintaining pressure stability and ensuring the correct amount of auxiliary combustion gas is added. The second pressure sensor automatically controls the replenishment gas pump, maintaining a dynamic pressure balance within the replenishment tank, ensuring complete combustion, improving fuel efficiency, and reducing user costs. Simultaneously, a one-way valve ensures unidirectional flow of the combustion-supporting gas, preventing backflow. A supplementary air pump ensures the pressure inside the supplementary tank remains higher than that inside the pressure stabilizing tank, also preventing fuel backflow and further enhancing the safety of the device. Fuel and combustion-supporting gas are sprayed through the outer and inner nozzles, working together to complete mixing and combustion. An adjusting plate creates a swirling airflow, ensuring thorough mixing of the fuel and combustion-supporting gas, guaranteeing uniform fuel spraying across the cross-section, and improving mixing efficiency. This ensures sufficient contact between the fuel and materials during combustion, improving heating efficiency. Furthermore, the user controls the electric push rod according to the production process. The push block drives the gear ring and adjusting plate for fine-angle adjustments within ±5 degrees. This device expands its application range by allowing for flame adjustment via adjustable plates at different angles. Independent control of multiple sets of external and internal nozzles at different positions enables individual control of each flame group, preventing damage to the inner wall of the suspension kiln. It also ensures omnidirectional flame distribution and adaptability based on the material's location, saving fuel while increasing the heating area and guaranteeing sintering quality. The device utilizes two combustion chambers and fuel channels, along with multiple sets of external and internal nozzles at different positions, to achieve more precise flame control, ensuring uniform fuel spraying across the cross-section without dead zones and guaranteeing full contact with the material. This not only improves sintering efficiency but also enhances fuel combustion efficiency.It can also be adjusted according to different production processes, expanding its application range and reducing its limitations. Simultaneously, it enhances user safety. Higher combustion efficiency and directional combustion not only improve the sintering quality of materials but also reduce production costs for users.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-9 One embodiment provided by the present invention: A dual-nozzle omnidirectional burner for a suspended kiln includes a suspended kiln body 1. The suspended kiln body 1 has two sets of combustion aid channels 2 inside, and fuel channels 3 are installed inside the combustion aid channels 2. One end of each combustion aid channel 2 is connected to a first outer pipe 4 fixedly connected to the suspended kiln body 1. A first inner pipe 5 connected to the fuel channel 3 is installed inside the first outer pipe 4. Four rows of outer nozzles 8 are connected to the surface of the combustion aid channels 2. Each outer nozzle 8 has an inner nozzle 9 connected to the fuel channel 3 inside. Inclined adjustment grooves 10 are correspondingly formed on the surface of the inner nozzles 9 and the inner wall of the outer nozzles 8. Adjustment plates 11 are evenly arranged between the inner nozzle 9 and the adjustment groove 10 via bearings. Gears 12 are fixedly connected to one end of each adjustment plate 11. A gear ring 13 that meshes with the gear 12 is connected to the inner wall of one end of the inner nozzle 9 via a bearing. A push block 14 is fixedly connected to one side of the gear 12. An electric push rod 15 is installed inside the inner nozzle 9 via a rotating shaft. The output end of the electric push rod 15 is connected to the push block 14 via a rotating shaft. A pressure stabilizing mechanism for stabilizing pressure is provided at one end of the first outer tube 4. A compensation mechanism for improving combustion efficiency is provided inside the pressure stabilizing mechanism. Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment, one end of the first outer tube 4 is connected to a second outer tube 6 that is interconnected with it. The second outer tube 6 is equipped with a second inner tube 7 that is connected to the first inner tube 5, which facilitates the simultaneous delivery of fuel and combustion-supporting gas to the device. A set of outer nozzles 8 is located at the bottom of the combustion-supporting channel 2, and three sets of outer nozzles 8 are located on the surface of the combustion-supporting channel 2 that are close to each other. The three sets of outer nozzles 8 are staggered to ensure that the fuel is sprayed evenly on the cross-section without dead corners, and to ensure full contact with the material, so as to achieve more comprehensive combustion. The inner nozzle 9 is fixedly connected with a heat insulation cover 16 for protecting the gear 12, gear ring 13, push block 14 and electric push rod 15, so as to avoid damage to them by high temperature and improve their service life. Please see Figure 2 , Figure 7 and Figure 8In this embodiment, the pressure stabilizing mechanism includes a flow stabilizing box 17. One end of the first outer tube 4 is connected to the flow stabilizing box 17. Inside the flow stabilizing box 17, a pressure stabilizing box 18 connected to the first inner tube 5 is fixedly connected. Both the flow stabilizing box 17 and the pressure stabilizing box 18 are equipped with a first pressure sensor 19. The control terminals of the first pressure sensors 19 are electrically connected to an external power supply through an external switch, facilitating the user to detect the real-time pressure of fuel and combustion-supporting gas. Inside the pressure stabilizing box 18, a control box 20 is fixedly connected. Inside the control box 20, an L-shaped flow limiting plate 21 is connected via a bearing. One side of the flow limiting plate 21 is in contact with one end of the first inner tube 5 to control the fuel input speed. One end of the flow limiting plate 21 is uniformly fixed. A spring 22 is fixed to the inner wall of the control box 20. A stop plate 23 is attached to one side of the flow-limiting plate 21. A threaded rod 24, connected to the control box 20 via a bearing, is threaded to one side of the stop plate 23. One end of the threaded rod 24 extends to the outside of the flow stabilizer box 17. Two sets of guide sleeves 25 are fixedly connected to the inner wall of the control box 20, located on both sides of the threaded rod 24. One end of each guide sleeve 25 is slidably connected to a guide rod 26 fixedly connected to the stop plate 23. The user can control the movement of the stop plate 23 by rotating the threaded rod 24. Simultaneously, the guide sleeves 25 and guide rods 26 ensure the stability of the stop plate 23's movement. When the stop plate 23 is no longer attached to one end of the flow-limiting plate 21, the pressure of the fuel itself will... When the flow restrictor 21 is opened, the gas can enter the pressure stabilizing box 18. The user rotates the threaded rod 24, causing the abutment 23 to move further away from one end of the flow restrictor 21. The greater the angle at which the fuel opens the flow restrictor 21, the greater the fuel intake, and vice versa. The user controls the distance between the abutment 23 and the flow restrictor 21 by rotating the threaded rod 24. The abutment 23 limits the flow restrictor 21, thus controlling the fuel feed rate. The user rotates the threaded rod 24 to the set position to set the fuel feed rate. When the fuel is connected, the fuel pressure opens the flow restrictor 21, and the flow restrictor 21 acts on the spring 22. When the fuel supply is turned off, the pressure inside the pressure stabilizing tank 18 decreases. At this time, under the action of the spring 22's own rebound force, the fuel passage can be quickly cut off, that is, one end of the first inner tube 5 is sealed and blocked. At the same time, rotating the threaded rod 24 in the opposite direction can completely cut it off, improving the safety of the device. During use, the user can detect the pressure of the fuel inside the pressure stabilizing tank 18 and the pressure of the combustion-supporting gas inside the flow stabilizing tank 17 through the first pressure sensor 19, thereby detecting the real-time pressure of the fuel and combustion-supporting gas during the use of the device, thus improving the safety of the user and facilitating the user to control the fuel feed rate. At the same time, it can also realize the unidirectional flow of fuel, improving the safety of the device. Please see Figure 8 and Figure 9In this embodiment, the compensation mechanism includes a replenishment box 27. The bottom end of the voltage regulator box 18 is fixedly connected to the replenishment box 27, which is in contact with the current regulator box 17. The inner wall of the bottom end of the voltage regulator box 18 is evenly provided with replenishment channels 28 that communicate with the replenishment box 27. One-way valves 29 are installed at the top of each replenishment channel 28. The inside of the replenishment box 27 is provided with a sealing plate 30 for sealing the replenishment channels 28. The bottom end of the sealing plate 30 is slidably connected to two sets of slide rails 31 that are fixedly connected to the inner wall of the replenishment box 27. The middle part of the sealing plate 30 is threadedly connected to a threaded rod 32 that is connected to the replenishment box 27 through a bearing. One end of the replenishment box 27... A motor 33 is installed, and the output end of the motor 33 is fixedly connected to the threaded rod 32. Supplementary air pumps 34 are installed on both sides of the supplementary tank 27. A second pressure sensor 35 is installed on the inner wall of one side of the supplementary tank 27. The user controls the supplementary amount of auxiliary combustion gas according to the production process to achieve premixing of fuel and auxiliary combustion gas, thereby improving fuel combustion efficiency. Based on the set content, the motor 33 is controlled to work. The output end of the motor 33 drives the threaded rod 32 to rotate. The rotating threaded rod 32 causes the sealing plate 30 to move, thus preventing the sealing plate 30 from sealing the supplementary channel 28. At this time, the auxiliary combustion gas inside the supplementary tank 27... Gas enters the pressure stabilizing tank 18 through the replenishment channel 28 and the one-way valve 29. Since the sealing plate 30 simultaneously opens or closes the three replenishment channels 28, and the intake volume of each replenishment channel 28 is a fixed value, the user can control the amount of gas supplied by opening or closing the replenishment channels 28 according to the sealing plate 30. The pressure of the gas supplied inside the replenishment tank 27 can be detected by the second pressure sensor 35. The replenishment gas pump 34 can replenish the gas supplied from the pressure stabilizing tank 17 to the replenishment tank 27, thereby ensuring the stability of the pressure inside the replenishment tank 27 and thus ensuring the amount of gas supplied, making it compatible with the gas supply. During material mixing, the second pressure sensor 35 automatically controls the operation of the supplementary air pump 34, ensuring that the pressure inside the supplementary tank 27 is in dynamic equilibrium, guaranteeing complete combustion of fuel, improving fuel efficiency, and reducing user costs. At the same time, the one-way valve 29 ensures unidirectional flow of the auxiliary combustion gas, preventing backflow. The supplementary air pump 34 also ensures that the pressure inside the supplementary tank 27 is always higher than the pressure inside the pressure stabilizing tank 18, preventing fuel backflow and further improving the safety of the device. This allows users to premix the auxiliary combustion gas and fuel according to production process requirements, improving fuel combustion efficiency. It should be noted that the adjusting plate 11 is movable inside the adjusting groove 10, and the movable angle is ±5 degrees, which makes it convenient for users to adjust the angle of the adjusting plate 11 and control the thickness and length of the flame according to the production process. The control end of the electric push rod 15 is electrically connected to the external power supply through an external switch, which makes it convenient for users to control the operation of this device. The control ends of the motor 33, the supplementary air pump 34, and the second pressure sensor 35 are all electrically connected to the external power supply through external switches, which makes it convenient for users to control the operation of this device. The supplementary channel 28 and the one-way valve 29 are both arranged in a matrix, which makes it convenient for users to accurately control the amount and speed of supplementary combustion gas.

[0018] Before using this device, the user should configure it according to the production process, setting the fuel intake volume. The user can control the movement of the abutment plate 23 by rotating the threaded rod 24. Simultaneously, the guide sleeve 25 and guide rod 26 ensure the stability of the abutment plate 23's movement. When the abutment plate 23 is no longer in contact with one end of the flow-limiting plate 21, the flow-limiting plate 21 is pushed open by the fuel's own pressure, allowing the gas to enter the pressure stabilizing box 18. The user rotates the threaded rod 24, causing the abutment plate 23 to move further away from one end of the flow-limiting plate 21. The greater the angle at which the fuel pushes open the flow-limiting plate 21, the greater the fuel intake volume, and vice versa. The user controls the distance between the abutment plate 23 and the flow-limiting plate 21 by rotating the threaded rod 24. The abutment plate 23 can... The flow restrictor 21 can be positioned to limit the fuel feed rate. The user can set the fuel feed rate by rotating the threaded rod 24 to the set position. When fuel is supplied, the fuel pressure pushes the flow restrictor 21 open, stretching the spring 22. When fuel is shut off, the pressure inside the pressure stabilizing tank 18 decreases. The spring 22's rebound force quickly cuts off the fuel passage, sealing one end of the first inner tube 5. Simultaneously, rotating the threaded rod 24 in the opposite direction completely cuts off the flow, improving the safety of the device. During use, the user can detect the fuel pressure and flow rate inside the pressure stabilizing tank 18 using the first pressure sensor 19. The pressure of the combustion-supporting gas inside the tank 17 can be detected to monitor the real-time pressure of the fuel and combustion-supporting gas during use, thereby improving user safety. Users control the amount of combustion-supporting gas replenishment according to the production process to achieve pre-mixing of fuel and combustion-supporting gas, thus improving fuel combustion efficiency. Based on the set content, the motor 33 is controlled to operate. The output end of the motor 33 drives the threaded rod 32 to rotate. The rotating threaded rod 32 causes the sealing plate 30 to move, thus preventing the sealing plate 30 from sealing the replenishment channel 28. At this time, the combustion-supporting gas inside the replenishment tank 27 enters the pressure stabilizing tank 18 through the replenishment channel 28 and the one-way valve 29. Since the sealing plate 30 simultaneously opens or closes the three sets of replenishment channels 28, and each set of replenishment channels 28... The intake volume of gas 8 is a fixed value, so the user can control the amount of combustion gas supplied by opening or closing the replenishment channel 28 according to the sealing plate 30. The pressure of the combustion gas inside the replenishment tank 27 can be detected by the second pressure sensor 35. The replenishment gas pump 34 can replenish the combustion gas inside the flow stabilization box 17 into the replenishment tank 27, thereby ensuring the stability of the pressure inside the replenishment tank 27 and thus ensuring the amount of combustion gas supplied. When it is mixed with fuel, the second pressure sensor 35 automatically controls the operation of the replenishment gas pump 34, so that the pressure inside the replenishment tank 27 is in dynamic balance, ensuring complete combustion of fuel, improving fuel efficiency, and reducing user costs. At the same time, the one-way valve 29 can ensure the unidirectional flow of combustion gas and prevent backflow.Meanwhile, the supplementary air pump 34 ensures that the pressure inside the supplementary tank 27 is always higher than that inside the pressure stabilizing tank 18, preventing fuel backflow and further improving the safety of the device. Fuel and combustion-supporting gas are sprayed through the outer nozzle 8 and inner nozzle 9, working together to complete mixing and combustion. The adjusting plate 11 creates a swirling airflow, ensuring thorough mixing of fuel and combustion-supporting gas, guaranteeing uniform fuel spraying across the cross-section, and improving mixing efficiency. This ensures sufficient contact between the fuel and materials during combustion, improving heating efficiency. Simultaneously, the user controls the electric push rod 15 according to the production process. The extension or retraction of the output end of the electric push rod 15 causes the gear 12 to rotate via the push block 14. The rotating gear 12 drives the gear ring 13 and the adjusting plate 11 to rotate, allowing for fine angle adjustment via the adjusting plate 11. With an adjustment range of ±5 degrees, the device's applicability is further enhanced. Different angles of the adjusting plate 11 can be used to adjust the fire... The length and thickness of the flame can be adjusted independently by controlling multiple sets of external nozzles 8 and internal nozzles 9 at different positions. This allows for individual control of the flame state of each set, preventing damage to the inner wall of the suspension kiln body 1. It also ensures omnidirectional flame distribution and allows for tailored adjustments based on the material's location, saving fuel while increasing the heating area and guaranteeing sintering quality. This device, through two sets of combustion aid channels 2 and fuel channels 3, as well as multiple sets of external nozzles 8 and internal nozzles 9 at different positions, enables more precise flame control, ensuring uniform fuel spraying across the cross-section without dead zones, guaranteeing full contact with the material. This not only improves sintering efficiency but also enhances fuel combustion efficiency. Furthermore, it can be adjusted according to different production processes, expanding its application range and reducing limitations, while also improving user safety. Higher combustion efficiency and directional combustion not only improve the sintering quality of the material but also reduce the user's production costs.
