Description

Technical Field

[0001] The present invention relates to the technical field of burners, and particularly to a regenerative burner dedicated to the melting of recycled aluminum. Background Art

[0002] Recycled aluminum refers to aluminum materials obtained by recycling and reprocessing waste aluminum products (such as waste aluminum alloys, aluminum chips, waste beverage cans, waste automotive parts, etc.). Recycled aluminum not only plays a positive role in environmental protection, but also has important significance in terms of economy and resource utilization. With the increasing global emphasis on resources, the recycling and regeneration of aluminum have become an important industry, and a huge circular economy system has gradually taken shape.

[0003] The recycling of recycled aluminum is mainly completed through the following steps: 1. Collection and classification of waste aluminum: Waste aluminum has a wide range of sources, mainly including waste aluminum alloys, waste beverage cans, waste automotive parts, aluminum chips, aluminum wire rods, etc. These waste aluminums are usually classified according to their composition, source, and use for subsequent processing.

[0004] 2. Cleaning and treatment: After the waste aluminum is collected, it needs to be cleaned to remove grease, dirt, and other impurities. During the cleaning process, water, chemical agents, or mechanical methods are usually used to remove pollutants. The cleaned aluminum materials are generally divided into pieces or chips of different sizes for further processing.

[0005] 3. Melting and refining: The cleaned waste aluminum is fed into a furnace for melting. During the melting process, the waste aluminum is heated to its melting point (about 660°C), and then decontaminated and refined. Furnace charge additives and temperature control technologies are usually used to remove impurities in the aluminum, so that the finally obtained recycled aluminum material reaches a high purity.

[0006] 4. Adjustment of aluminum alloy: During the production process of recycled aluminum, the alloy composition of aluminum may be adjusted as needed. By adding appropriate alloying elements (such as copper, magnesium, silicon, etc.), the recycled aluminum can meet specific physical and chemical requirements and be suitable for different industrial applications.

[0007] 5. Casting and cooling of aluminum ingots: The refined aluminum liquid is cast into aluminum ingots, and after the aluminum ingots are cooled and solidified, they become aluminum materials that can be reused. These aluminum ingots can be used as raw materials in fields such as automotive manufacturing, building materials, and electrical products.

[0008] The melting of aluminum is an important process in the production of recycled aluminum, and improving energy efficiency during the smelting process is crucial for reducing production costs and minimizing resource waste. The application of regenerative burners makes the aluminum melting process more efficient, thus playing an important role in reducing energy consumption and enhancing production efficiency.

[0009] A regenerative burner is a device that uses regenerative materials to preheat air or fuel gas. In a regenerative burner, the heat generated by combustion is absorbed and stored by the regenerative materials (usually ceramics, refractory bricks, etc.). Then, when combustion is required, these regenerative materials release the stored heat to the fuel gas or air, preheating the air or fuel gas and thereby improving combustion efficiency.

[0010] The core advantage of a regenerative burner is that it can reduce energy waste and achieve higher temperatures and thermal efficiencies during the aluminum smelting process. By using a regenerative burner, the temperature inside the furnace can reach a higher level in a shorter time, thereby accelerating the aluminum melting process.

[0011] During the aluminum melting process, the efficiency of the burner directly affects the melting speed and energy consumption. Traditional combustion methods require large amounts of fuel gas and air to maintain the furnace temperature, which not only increases energy costs but also leads to instability in the melting process. The regenerative burner preheats the fuel gas or air, raising the temperature inside the furnace before combustion, thus effectively improving combustion efficiency and reducing unnecessary energy waste.

[0012] Specifically, a regenerative burner can: Improve thermal efficiency: By storing and reusing thermal energy, energy waste is reduced.

[0013] Accelerate the melting process: A higher furnace temperature means a faster aluminum melting speed, thus enhancing production efficiency.

[0014] Stabilize temperature control: The regenerative burner can better control temperature fluctuations and ensure the stability of the melting process.

[0015] During the aluminum smelting process, due to the high melting point of aluminum, a large amount of energy is consumed. The regenerative burner helps reduce energy consumption by improving combustion efficiency, thereby reducing production costs. In addition, the regenerative burner can also reduce greenhouse gas emissions, meeting modern environmental protection requirements.

[0016] By using regenerative burners, the aluminum smelting industry can reduce its dependence on energy sources such as fuel gas and coal, lower greenhouse gas emissions, and reduce environmental pollution. Therefore, the application of regenerative burners not only improves production efficiency but also helps promote the development of the aluminum industry towards a green and low-carbon direction.

[0017] With the global emphasis on sustainable development and the circular economy, the recycling and reproduction industry of aluminum has developed rapidly. Recycled aluminum not only reduces production costs but also plays a positive role in environmental protection. In the future, with the continuous progress of recycling technology, the aluminum recovery rate will gradually increase, and the application fields of recycled aluminum will also continue to expand.

[0018] Construction industry: Aluminum materials are widely used in the construction industry due to their excellent corrosion resistance, light weight, and aesthetics. The application of recycled aluminum can effectively reduce the cost of building materials and reduce the demand for primary aluminum.

[0019] Automobile industry: The application of recycled aluminum in automobile manufacturing is also becoming increasingly widespread, especially in the field of electric vehicles. Aluminum materials are widely used in vehicle bodies, engine components, and wheels, etc. Using recycled aluminum to produce automobile parts can not only reduce costs but also reduce carbon emissions in automobile production.

[0020] Packaging industry: The recycling and reprocessing of used beverage cans have promoted the application of aluminum in the packaging industry. The use of recycled aluminum makes packaging materials more environmentally friendly and reduces production costs.

[0021] Electronics industry: Recycled aluminum is widely used in the electronics industry. Especially when manufacturing the casings of electronic products, recycled aluminum can reduce the dependence on primary aluminum, lower production costs, and has excellent physical properties.

[0022] As an important green material, the recycling and reprocessing of recycled aluminum not only help save natural resources but also reduce energy consumption and environmental pollution. The regenerative burner greatly improves production efficiency and reduces energy consumption by enhancing combustion efficiency and accelerating the melting process during the aluminum smelting process, which is an important development direction of modern aluminum smelting technology. With the continuous progress of recycling technology, recycled aluminum will be applied in more fields, promoting the aluminum industry to develop towards a more environmentally friendly and sustainable direction.

[0023] When a traditional regenerative burner is in use, first, external air is inhaled through an external blower and transported to the inside of the regenerative burner for heating. Subsequently, fuel injected through the liquid supply pipe is ejected through a nozzle for combustion.

[0024] Although the traditional regenerative burner can complete the combustion operation, before transporting the external air to the inside of the regenerative burner, there is a lack of a structure for filtering air. The external air usually carries impurities such as dust and particulate matter. These impurities are directly transported to the inside of the regenerative burner without being treated and deposited on the surface of the regenerator, thereby affecting the overall combustion efficiency. Summary of the Invention

[0025] To make up for the above deficiencies, the present invention provides a regenerative burner dedicated to the melting of recycled aluminum, aiming to improve the problem that in the prior art, before the external air is transported into the interior of the regenerative burner, there is a lack of a structure for filtering air, and the external air usually carries impurities such as dust and particulate matter.

[0026] To achieve the above object, the present invention provides the following technical solutions: A regenerative burner dedicated to the melting of recycled aluminum, including a regenerative burner body. A mounting shell is fixedly connected to the right side of the exterior of the regenerative burner body. A filtering assembly is arranged inside the mounting shell, and a melting assembly is arranged on the left side of the exterior of the regenerative burner body; The filtering assembly includes a blower, which is installed on the right side inside the mounting shell. A mounting plate is arranged on the left side inside the mounting shell. A coarse filter plate is fixedly connected to the lower right side of the mounting plate, and a sponge adsorption rod is fixedly connected to the lower left side of the mounting plate. A fine filter plate is arranged in the middle of the coarse filter plate and the sponge adsorption rod, and the fine filter plate is fixedly connected to the middle of the mounting plate. A disassembly and assembly component is arranged on the right side of the exterior of the mounting shell.

[0027] Further, the disassembly and assembly component includes an L-shaped frame, which is fixedly connected to the right side of the exterior of the mounting shell. A fixing rod is fixedly connected to the middle of the L-shaped frame. A moving plate is slidably connected to the exterior of the fixing rod. A spring is sleeved on the exterior of the fixing rod. A pull ring is fixedly connected to the right side of the exterior of the moving plate, and a plug is fixedly connected to the left side of the exterior of the moving plate.

[0028] Further, the melting assembly includes a furnace body, which is fixedly connected to the left side of the exterior of the regenerative burner body. A mounting block is fixedly connected to the upper part of the furnace body. A furnace cover is rotatably connected inside the mounting block, and a handle is fixedly connected to the upper part of the furnace cover.

[0029] Further, an air inlet hood is installed on the right side of the exterior of the mounting shell.

[0030] Further, a spray pipe is fixedly connected to the upper part of the regenerative burner body, the top of the spray pipe is fixedly connected to the inside of the furnace body, and a liquid inlet pipe is fixedly connected to the upper part of the spray pipe.

[0031] Further, an air suction pipe is fixedly connected to the left side of the exterior of the regenerative burner body, and the top of the air suction pipe is fixedly connected to the inside of the furnace body.

[0032] Further, a through hole one is opened on the upper part of the mounting shell, and the mounting plate is slidably connected to the inside of the through hole one.

[0033] Furthermore, a second through hole is opened on the right side of the outside of the installation shell, the plug block is slidably connected to the inside of the second through hole, a slot is opened inside the installation plate, the plug block is plugged into the slot, and a socket is opened on the right side of the outside of the installation shell.

[0034] The burner control method comprises the following steps: ① To transport external air to the interior of the regenerative burner body, first, start the fan to generate suction force, and suck the external air into the interior of the installation shell through the air inlet cover; ②Then, the air entering the installation shell is filtered through the coarse filter plate to remove large particles in the air, and then through the fine filter plate to remove small particles remaining in the air; ③ The sponge adsorption rod absorbs small particles and odors to ensure the cleanliness of the air. The air after multi-layer filtration and purification is transported to the inside of the regenerative burner body, so that when the external air is transported to the inside of the regenerative burner body, the multi-stage filtration structure can effectively reduce the impact of impurities in the external air on the burner and improve the combustion efficiency; ④ When the filter structure needs to be disassembled and cleaned, first, pull the pull ring to move the external fixed moving plate outside the fixed rod. When the moving plate moves, the plug-in block fixed on the left side of the outside moves synchronously. At the same time, squeeze the spring sleeved on the outside of the fixed rod to make the spring deform under force; ⑤ When the plug-in block is out of the slot, the rotating pull ring drives the movable plate to rotate outside the fixed rod, and the movable plate drives the plug-in block fixed on the left side to rotate synchronously. When the plug-in block and the movable plate rotate to the position of the socket, the pull ring inserts the plug-in block into the socket under the reaction force of the spring. At this time, the mounting plate can move freely, and the operator can lift the mounting plate upwards to move the coarse filter plate, fine filter plate and sponge adsorption rod installed at the bottom out of the mounting shell; ⑥ Clean the coarse filter plate, fine filter plate and sponge adsorption rod. During installation, insert the mounting plate and the coarse filter plate, fine filter plate and sponge adsorption rod fixed at the bottom into the interior of the mounting shell through the through hole. Then, pull the pull ring to disengage the plug from the inside of the socket. Then, rotate the pull ring to move the movable plate and the plug synchronously. When the plug is located at the position of the socket, release the pull ring. Under the reaction force of the spring, insert the plug into the interior of the card slot, thereby facilitating the disassembly and cleaning of the filter structure, extending the service life of the filter structure and reducing the replacement cost.

[0043] Furnace cover and handle: They facilitate the operation of opening and closing the furnace body by the operator.

[0044] 5. Air inlet hood and liquid inlet pipe: They provide necessary air circulation and liquid input to ensure the smooth progress of the melting process.

[0045] 6. Suction pipe: It is used to suck in necessary gases or air, which helps to control the internal environment of the furnace body.

[0046] 7. Through-hole design: It provides installation space for sliding and mounting plates, and at the same time ensures firm installation through the insertion block and slot structure.

[0047] Generally speaking, through the reasonable layout and cooperation of each component in this application, efficient filtration and stable melting operation during the recycling aluminum melting process are ensured.

[0048] The structure of the regenerative burner dedicated to the melting of recycled aluminum of the present invention combines multiple innovative designs, which can effectively improve the efficiency, environmental protection and operation convenience during the recycling aluminum melting process. The following are the beneficial effects of the present invention: Efficient energy utilization and energy-saving effect: Through a reasonably designed regenerative heat storage system, the regenerative burner can maximize the utilization of the heat energy generated during the combustion process, thereby reducing energy waste. Different from the traditional direct combustion heating method, the regenerative burner can store the heat energy and release it when needed. This design significantly improves the thermal efficiency of the burner and enables it to work continuously and stably under low energy consumption conditions. Specifically, the regenerative burner body is made of special materials that can store a large amount of heat energy at high temperatures. When the burner consumes heat energy during operation, the heat storage body will absorb and store the heat. When a higher temperature is required, the heat storage body will release the stored heat energy, thus reducing additional fuel consumption. This not only reduces the energy cost but also decreases the emission of greenhouse gases, meeting the current environmental protection and energy-saving trends. Improving the efficiency of aluminum smelting: The design of the present invention also has significant advantages in improving the efficiency of aluminum smelting. Traditional aluminum smelting processes often require long-term high-temperature heating, which is time-consuming and energy-consuming. After adopting the regenerative burner, through a reasonable heat storage and release mechanism, the smelting process can be made more stable and efficient. By optimizing the temperature control system of the burner, the temperature inside the furnace can be accurately regulated according to actual needs, avoiding the excessive oxidation of molten aluminum or the generation of aluminum chips caused by large temperature fluctuations in the traditional method. In addition, the design of the furnace body and the burner ensures uniform heat distribution, preventing local overheating or uneven cooling, thus further improving the quality of molten aluminum during the smelting process and reducing the waste of molten aluminum in production. Good filtering effect to ensure the quality of molten aluminum: In the burner design of the present invention, advanced filtering components are integrated, which can effectively remove various impurities generated during the smelting process and ensure the high purity and quality of molten aluminum. During the smelting process of aluminum, molten aluminum reacts with oxygen, nitrogen, and other impurities in the air, resulting in an increase in impurities in the molten aluminum, which affects its subsequent processing and product quality. To avoid this situation, the burner is specially equipped with multiple filtering devices such as coarse filter plates, sponge adsorption rods, and fine filter plates. The combination of the coarse filter plate and the sponge adsorption rod can quickly remove large particle impurities generated during the smelting process, while the fine filter plate is responsible for further filtering fine impurities to ensure that the purity of molten aluminum reaches a higher standard. This design greatly improves the quality of molten aluminum, reduces the defective rate caused by impurities during subsequent processing, and ensures the quality of the final product. Disassembly and assembly component design for easy maintenance and cleaning: In the burner structure of the present invention, the design of the disassembly and assembly components is also an important highlight. Due to long-term high-temperature use inside the burner, a large amount of dust, impurities or molten substances may accumulate. To facilitate cleaning and maintenance, a modular disassembly and assembly component design is considered. For example, the burner body is connected through an L-shaped frame and a fixed rod, and can be easily disassembled. During disassembly, the operator can quickly separate each component through devices such as pull rings and insertion blocks, reducing the time and labor intensity required for cleaning and maintenance. In addition, the spring design in the burner enables certain moving plates to slide freely on the fixed rod. This design not only facilitates the disassembly and assembly of components, but also improves the stability and durability of the equipment during long-term use. After disassembling the components, the operator can more intuitively inspect and clean each part, ensuring that the burner always maintains the best working condition and extending the service life of the equipment; Safety design: Safety has always been an important aspect that cannot be ignored in industrial equipment. In the burner design of the present invention, through reasonable structural layout and strict material selection, the safety of the equipment is maximized. For example, the connection between the furnace body and the burner body uses a stable fixing device to ensure that the equipment is not prone to loosening or leakage under high-temperature and high-pressure environments. The design of components such as the intake pipe and the suction pipe also takes into account the smooth flow of air and the prevention of leakage. The design of the air inlet hood ensures smooth air circulation, which helps to maintain the oxygen supply inside the burner and prevent dangers caused by poor air circulation. In addition, the burner is also equipped with multiple protection devices during the design process, such as temperature sensors and pressure monitoring. Once an abnormal situation occurs, the system can automatically shut down the burner to prevent accidents; Environmental protection effect: Environmental protection is one of the key concerns in the current industrial field. The burner design of the present invention takes into account environmental protection requirements in many aspects. First of all, the regenerative burner reduces energy consumption and emissions through efficient heat energy utilization. Secondly, the filtration system can effectively remove harmful gases and impurities generated during the smelting process, reducing pollution to the atmospheric environment. Through reasonable structural design and efficient energy utilization, the energy loss during the entire smelting process is minimized, and the harmful gases and solid waste emissions are also effectively controlled. This not only meets the environmental protection standards of modern industry, but also helps to reduce the investment of enterprises in environmental protection; Easy to operate and reduce labor intensity: Finally, the design of the present invention takes into account the ease of operation. Through the integrated disassembly and assembly components and modular design, the operator can easily install, clean, repair and inspect the equipment, greatly reducing the operation difficulty and labor intensity. At the same time, the temperature control system and intelligent design of the regenerative burner enable the operator to complete the entire smelting process by simply adjusting parameters such as temperature and air flow, reducing the possibility of manual intervention and operation errors; Through the innovative design of the regenerative burner, combined with multiple advantages such as efficient filtration, energy conservation and environmental protection, safety guarantee, and convenient operation, the present invention not only has remarkable effects in improving the aluminum melting efficiency, reducing energy consumption, and environmental protection, but also ensures the long-term stable operation and easy maintainability of the equipment through convenient disassembly and assembly components and modular design. With the continuous progress of technology, this regenerative burner will play a greater role in the aluminum processing industry and even other metal melting fields, contributing to energy conservation, emission reduction, and production efficiency improvement in related industries.

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] Refer to Figures 1 - 3, an embodiment provided by the present invention: a regenerative burner for special use in remelting aluminum, comprising a regenerative burner body 4. A mounting shell 8 is fixedly connected to the right side of the outside of the regenerative burner body 4. A filtering component is arranged inside the mounting shell 8. By arranging the filtering component, it is convenient to filter the air entering the inside of the regenerative burner body 4. A melting component is arranged on the left side of the outside of the regenerative burner body 4. By arranging the melting component, it is convenient to carry out the melting operation on the recycled aluminum. The melting component includes a furnace body 1. The furnace body 1 is fixedly connected to the left side of the outside of the regenerative burner body 4. An installation block 2 is fixedly connected to the upper part of the furnace body 1. A furnace cover 3 is rotatably connected inside the installation block 2. A handle is fixedly connected to the upper part of the furnace cover 3. During melting, the furnace cover 3 is moved away from the upper part of the furnace body 1 through the handle. Subsequently, the recycled aluminum is put into the inside of the furnace body 1, and then the furnace cover 3 is covered. A spray pipe 5 is fixedly connected to the upper part of the regenerative burner body 4. The top of the spray pipe 5 is fixedly connected to the inside of the furnace body 1, and is used to evenly spray fuel or high-temperature gas after combustion into the combustion area of the furnace body 1. A liquid inlet pipe 6 is fixedly connected to the upper part of the spray pipe 5. The liquid inlet pipe 6 is used to transport fuel into the spray pipe 5 to ensure the continuity and stability of the combustion process. An air suction pipe 7 is fixedly connected to the left side of the outside of the regenerative burner body 4. The top of the air suction pipe 7 is fixedly connected to the inside of the furnace body 1, and is used to suck the waste gas or high-temperature gas in the furnace body 1 into the regenerative burner body 4 for heat recovery; The filtering component includes a fan 10. The fan 10 is installed on the right side inside the mounting shell 8. An installation plate 11 is arranged on the left side inside the mounting shell 8. A coarse filter plate 12 is fixedly connected to the lower right side of the installation plate 11. By arranging the coarse filter plate 12, it is convenient to filter larger particles in the air. A sponge adsorption rod 14 is fixedly connected to the lower left side of the installation plate 11. By arranging the sponge adsorption rod 14, it is convenient to adsorb tiny impurities and peculiar smells in the air. A fine filter plate 13 is arranged between the coarse filter plate 12 and the sponge adsorption rod 14. By arranging the fine filter plate 13, it is convenient to filter smaller impurities in the air. The fine filter plate 13 is fixedly connected to the middle of the installation plate 11. A disassembly and assembly component is arranged on the right side outside the mounting shell 8. By arranging the disassembly and assembly component, it is convenient to disassemble and clean the filtering structure. An air inlet hood 9 is installed on the right side outside the mounting shell 8. By arranging the air inlet hood 9, it is convenient for external air to enter. A through hole 1 23 is opened in the upper part of the mounting shell 8. The installation plate 11 is slidably connected inside the through hole 1 23. By arranging the through hole 1 23, it is convenient for the installation plate 11 to move.

[0052] Specifically, when delivering external air to the inside of the regenerative burner body 4, first, start the blower 10. The blower 10 generates a strong suction force to suck the external air into the inside of the mounting shell 8 through the air inlet hood 9. Subsequently, the air entering the inside of the mounting shell 8 is first preliminarily filtered by the coarse filter plate 12, which can effectively intercept larger particulate matters in the air, such as dust, sand grains, and other visible impurities. The air filtered by the coarse filter plate 12 then passes through the fine filter plate 13 for secondary filtration, which can capture the remaining smaller particulate matters in the air, such as fine dust, metal particles, etc. Finally, the air passes through the sponge adsorption rod 14 for deep purification, which can adsorb the tiny particulate matters in the air, effectively remove odors and some harmful gases. The air after multi-layer filtration is ultimately delivered to the inside of the regenerative burner body 4. Through the multi-stage filtration structure, the influence of impurities in the external air on the burner can be significantly reduced, and the deposition of impurities on the surface of the regenerator can be avoided, thereby improving the combustion efficiency.

[0053] Referring to Figures 4 - 6 , the disassembly and assembly component includes an L-shaped frame 15. The L-shaped frame 15 is fixedly connected to the outer right side of the mounting shell 8. A fixed rod 16 is fixedly connected to the middle of the L-shaped frame 15. A moving plate 18 is slidably connected to the outside of the fixed rod 16. A spring 17 is sleeved on the outside of the fixed rod 16. A pull ring 19 is fixedly connected to the outer right side of the moving plate 18. The pull ring 19 is provided to facilitate the operation of the operator. A plug 20 is fixedly connected to the outer left side of the moving plate 18. A through hole two 24 is opened on the outer right side of the mounting shell 8. The plug 20 is slidably connected to the inside of the through hole two 24. The through hole two 24 is provided to facilitate the movement of the plug 20. A clamping groove 21 is opened in the mounting plate 11. The plug 20 is inserted into the clamping groove 21, improving the installation stability of the filter structure. A jack 22 is opened on the outer right side of the mounting shell 8. When disassembling, the jack 22 facilitates the placement of the plug 20 and avoids the plug 20 affecting the disassembly process.

[0054] Specifically, when the filter structure needs to be disassembled and cleaned, the operator first pulls the pull ring 19. The pull ring 19 drives the externally fixed moving plate 18 to move outside the fixed rod 16. The movement of the moving plate 18 will drive the plug 20 fixed to the left side of its exterior to move synchronously. During this process, the moving plate 18 squeezes the spring 17 sleeved outside the fixed rod 16, causing the spring 17 to undergo elastic deformation under force and store a certain amount of energy. When the plug 20 completely disengages from the inside of the card slot 21, the operator can rotate the pull ring 19 to drive the moving plate 18 to rotate outside the fixed rod 16. At the same time, the moving plate 18 will drive the plug 20 fixed to the left side of its exterior to rotate synchronously. When the plug 20 and the moving plate 18 rotate to the position of the jack 22, the operator releases the pull ring 19. At this time, the spring 17 returns to its original state under the action of the reaction force, pushing the moving plate 18 and the plug 20 to move, so that the plug 20 is inserted into the inside of the jack 22. At this time, the mounting plate 11 can move freely. The operator can lift the mounting plate 11 upward to remove the coarse filter plate 12, the fine filter plate 13, and the sponge adsorption rod 14 installed at its lower part from the inside of the mounting shell 8. After removal, the operator can clean the coarse filter plate 12, the fine filter plate 13, and the sponge adsorption rod 14 to remove the dust, particulate matter, and other impurities accumulated on their surfaces and inside. When installing the filter structure, the operator inserts the mounting plate 11 and the coarse filter plate 12, the fine filter plate 13, and the sponge adsorption rod 14 fixed to its lower part through the through hole 23 into the inside of the mounting shell 8. Subsequently, the operator pulls the pull ring 19 again to disengage the plug 20 from the inside of the jack 22. Then, rotate the pull ring 19 to drive the moving plate 18 and the plug 20 to move synchronously. When the plug 20 moves to the position of the card slot 21, the operator releases the pull ring 19. At this time, the reaction force of the spring 17 pushes the plug 20 into the inside of the card slot 21 to complete the fixed installation of the filter structure. By disassembling and cleaning the filter structure, the service life of the filter structure can be extended and the replacement cost can be reduced.

[0055] The control method of this burner includes the following steps: ① Deliver the external air to the inside of the regenerative burner body 4. First, start the fan 10. Through the suction generated by the fan 10, suck the external air into the inside of the mounting shell 8 through the air inlet hood 9; ② Subsequently, the air entering the inside of the mounting shell 8 is filtered by the coarse filter plate 12 for large particulate matter in the air, and then filtered by the fine filter plate 13 for the remaining small particulate matter in the air; ③ Through the sponge adsorption rod 14, adsorb small particulate matter and odors to ensure the cleanliness of the air. The air after multi-layer filtration and purification is delivered to the inside of the regenerative burner body 4, thereby realizing that when delivering the external air to the inside of the regenerative burner body 4, the multi-stage filter structure can effectively reduce the influence of impurities in the external air on the burner and improve the combustion efficiency; ④ When it is necessary to disassemble and clean the filter structure, first, pull the pull ring 19 to move the externally fixed moving plate 18 outside the fixed rod 16. When the moving plate 18 moves, the plug 20 fixed to the left side externally moves synchronously. At the same time, the spring 17 sleeved outside the fixed rod 16 is squeezed, causing the spring 17 to deform under force; ⑤ When the plug 20 disengages from the inside of the card slot 21, rotate the pull ring 19 to drive the moving plate 18 to rotate outside the fixed rod 16. At the same time, the moving plate 18 drives the plug 20 fixed to the left side externally to rotate synchronously. When the plug 20 and the moving plate 18 rotate to the position of the jack 22, under the reaction force of the spring 17, the pull ring 19 inserts the plug 20 into the inside of the jack 22. At this time, the mounting plate 11 can move freely, and the operator can lift the mounting plate 11 upward to move the coarsely filtered plate 12, the finely filtered plate 13, and the sponge adsorption rod 14 installed below out of the inside of the mounting shell 8; ⑥ Clean the coarsely filtered plate 12, the finely filtered plate 13, and the sponge adsorption rod 14. During installation, insert the mounting plate 11 and the coarsely filtered plate 12, the finely filtered plate 13, and the sponge adsorption rod 14 fixed below into the inside of the mounting shell 8 through the first through hole 23. Subsequently, pull the pull ring 19 to make the plug 20 disengage from the inside of the jack 22. Then, rotate the pull ring 19 to drive the moving plate 18 and the plug 20 to move synchronously. When the plug 20 is at the position of the jack 22, release the pull ring 19, and under the reaction force of the spring 17, insert the plug 20 into the inside of the card slot 21, thus facilitating the disassembly and cleaning of the filter structure, prolonging the service life of the filter structure, and reducing the replacement cost.
