Description

A burner with a gas purification structure Technical Field

[0001] This utility model relates to the field of seedling cultivation technology, and in particular to a burner with a gas purification structure. Background Technology

[0002] In the fields of energy utilization and industrial production, burners, as core equipment for achieving efficient fuel combustion and releasing heat energy, are widely used in various heating, power generation, and chemical production scenarios. With increasingly stringent environmental standards and ever-increasing demands for equipment operational stability and efficiency in industrial production, the impact of burner intake air quality on the combustion process is receiving increasing attention.

[0003] Chinese Patent Publication No. CN110249178B discloses a layered burner comprising: a venturi tube in fluid communication with and connected to a chamber, the chamber being in fluid communication with multiple rows of burner ports, the chamber having an outer wall and an inner wall; a plurality of blades having a layered arrangement, wherein the lowermost blade of the plurality of blades is the smallest blade; each of the plurality of blades having an inner edge extending from the inner wall toward the center of the plurality of blades and extending above one row of burner ports, such that flames emitted from this row of burner ports are impacted from above and thus guided toward the center of the plurality of blades; and the venturi tube having: a constricted middle portion; a first end that forms a connection to the chamber; and a second end configured to receive fuel gas from a gas source.

[0004] Currently, existing burners have many shortcomings in terms of air intake treatment:

[0005] On the one hand, the intake air of burners usually comes directly from the external environment or from gas supply systems that have not undergone deep purification. This intake air often contains a large amount of dust, particulate impurities, oil, and some harmful chemicals. During combustion, these impurities not only adhere to key parts inside the burner, such as nozzles and combustion chamber walls, causing nozzle blockage and narrowing of airflow channels, thus affecting fuel atomization and combustion efficiency, resulting in incomplete combustion and energy waste; but also, these impurities may undergo chemical reactions under high-temperature combustion conditions, generating new pollutants, exacerbating the pollution of the environment by exhaust emissions, and making it difficult to meet increasingly stringent environmental regulations.

[0006] On the other hand, existing burners with certain air intake purification functions mostly employ fixed installations for their purification structures, such as welding or integral molding onto the burner body. While this design ensures the stability of the purification structure to some extent, it brings significant inconvenience in actual use. When the purification structure accumulates a large amount of impurities due to long-term use, leading to a decrease in purification efficiency or even complete failure, the inability to easily disassemble the purification components for cleaning or replacement necessitates shutting down the entire burner for maintenance or replacing the purification module. This not only increases equipment maintenance and time costs but also severely impacts production continuity and efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a burner with a gas purification structure, which achieves air intake purification through a filter screen and facilitates easy assembly and disassembly of the mounting ring through snap-fit ​​components and snap rings. While improving the combustion efficiency of the burner and reducing pollutant emissions, it significantly simplifies the maintenance process and reduces maintenance costs, resulting in significant economic and environmental benefits and bringing a new breakthrough to the development and application of burner technology.

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0009] A burner with a gas purification structure includes:

[0010] The burner body and the burner inlet pipe installed on the air inlet of the burner body are provided. The air inlet end of the burner inlet pipe is equipped with a filter assembly for filtration. The filter assembly includes a filter shell installed at the end of the burner inlet pipe. A detachable mounting ring is installed on the side of the filter shell. A filter screen is fixedly connected to the inner wall of the mounting ring.

[0011] In the aforementioned burner with a gas purification structure, the side of the mounting ring is provided with a sealing ring that matches the filter housing.

[0012] In the aforementioned burner with a gas purification structure, the mounting ring is further provided with a snap-fit ​​assembly for fixing the mounting ring, and a retaining ring is installed on the filter housing at a position corresponding to the snap-fit ​​assembly.

[0013] In the aforementioned burner with a gas purification structure, the snap-fit ​​assembly includes a sliding snap rod fixedly connected to the side of the mounting ring. The top and bottom of the sliding snap rod are provided with mounting grooves. A connecting spring is fixedly connected to the inner wall of the mounting groove. The other end of the connecting spring is fixedly connected to a sliding snap block that matches the snap ring.

[0014] In the aforementioned burner with a gas purification structure, both sides of the sliding block are fixedly connected to limit sliders, and a limit groove is formed on the inner wall of the mounting groove corresponding to the position of the limit slider.

[0015] In the aforementioned burner with a gas purification structure, a spring and a slip ring are sequentially fitted onto the sliding lever.

[0016] In the aforementioned burner with a gas purification structure, one end of the sleeve spring is fixedly connected to the side of the mounting ring, and the other end of the sleeve spring is fixedly connected to the side of the slip ring.

[0017] This utility model has at least the following beneficial effects:

[0018] 1. This utility model realizes a burner with a gas purification structure, which achieves air purification through a filter screen and facilitates easy disassembly and assembly of the mounting ring through a snap-fit ​​component and snap ring. While improving the combustion efficiency of the burner and reducing pollutant emissions, it significantly simplifies the maintenance process and reduces maintenance costs, resulting in significant economic and environmental benefits and bringing a new breakthrough to the development and application of burner technology.

[0019] 2. To improve the quality of the burner's intake air and optimize the combustion process, this invention filters the intake air of the burner body using a filter screen. This filter screen effectively intercepts harmful substances such as dust, particulate impurities, and oil in the intake air, significantly improving its quality. After the purified gas enters the burner, the fuel mixes more thoroughly with the air, improving atomization and resulting in a more stable and efficient combustion process. This not only improves fuel combustion efficiency, reduces energy waste, and lowers production costs, but also significantly reduces the generation of harmful substances due to more complete combustion, resulting in a substantial decrease in pollutant concentrations in exhaust emissions. This strongly promotes the development of burners towards green and environmentally friendly practices, meets increasingly stringent environmental regulations, and provides strong support for the sustainable development of enterprises.

[0020] 3. To simplify the maintenance process and reduce costs of burner purification components, this invention utilizes a snap-fit ​​assembly and a retaining ring to facilitate easy installation and removal of the mounting ring. The ingenious design of the snap-fit ​​assembly and retaining ring makes the installation and removal of the mounting ring extremely simple. During daily use, when the filter screen needs cleaning or maintenance due to excessive accumulation of impurities, workers can quickly remove the mounting ring from the burner body without the need for specialized tools, using only a simple snap-fit ​​operation to thoroughly clean or replace the filter screen. After cleaning or maintenance, the mounting ring can be quickly reinstalled, restoring the burner to normal operation. This convenient installation and removal method significantly shortens burner maintenance time, reduces equipment downtime, and effectively improves production continuity and efficiency. Furthermore, since no specialized technicians are required for complex disassembly and installation operations, maintenance and labor costs are reduced, making burner maintenance more economical and efficient.

[0036] Please refer to Figures 1 to 5. An embodiment of this utility model provides a burner with a gas purification structure, including: a burner body 1 and a burner inlet pipe 2 installed on the air inlet of the burner body 1. A filter assembly 3 for filtering is installed at the air inlet end of the burner inlet pipe 2. The filter assembly 3 includes a filter shell 301 installed at the end of the burner inlet pipe 2. A detachable mounting ring 3011 is installed on the side of the filter shell 301. A filter screen 3012 is fixedly connected to the inner wall of the mounting ring 3011.

[0037] By adopting the above technical solutions, the intake air is purified through the filter screen 3012, and the installation ring 3011 is designed for easy disassembly and assembly through the snap-fit ​​component 302 and the snap ring 303. At the same time, the combustion efficiency of the burner is improved and the pollutant emissions are reduced, the maintenance process is significantly simplified and the maintenance cost is reduced. It has significant economic and environmental benefits and brings new breakthroughs to the development and application of burner technology.

[0038] In order to increase the sealing performance of the connection between the mounting ring 3011 and the filter housing 301, in this embodiment, a sealing ring 30111 matching the filter housing 301 is provided on the side of the mounting ring 3011.

[0039] To facilitate the fixed installation of the mounting ring 3011 on the side of the filter housing 301, in this embodiment: the mounting ring 3011 is also provided with a snap-fit ​​component 302 for fixing the mounting ring 3011, and a retaining ring 303 is installed on the filter housing 301 at the position corresponding to the snap-fit ​​component 302. The snap-fit ​​component 302 includes a sliding retaining rod 3021 fixedly connected to the side of the mounting ring 3011. The top and bottom of the sliding retaining rod 3021 are provided with mounting grooves 3022. A connecting spring 3023 is fixedly connected to the inner wall of the mounting groove 3022, and a sliding retaining block 3024 matching the retaining ring 303 is fixedly connected to the other end of the connecting spring 3023.

[0040] In order to limit the sliding block 3024 and increase the stability of the engagement between the sliding block 3024 and the retaining ring 303, in this embodiment: limit sliders 30241 are fixedly connected to both sides of the sliding block 3024, and limit grooves 30242 are formed on the inner wall of the mounting groove 3022 at the position corresponding to the limit sliders 30241.
