Description

A windproof device for a heating furnace burner Technical Field

[0001] This utility model relates to the field of heating furnace technology, and in particular to a windproof device for heating furnace burners. Background Technology

[0002] A natural gas heater is an industrial heating device that uses natural gas as fuel. It is mainly used in metal heat treatment, forging, smelting, annealing, and other processes, heating workpieces to the target temperature by burning natural gas to generate high-temperature heat energy. The burner (also known as a gas burner) is the core component of a natural gas heater, responsible for mixing and igniting natural gas with combustion air to form a stable flame. It typically consists of a gas cap, air cyclone vanes, ignition electrodes, and a flame stabilizer plate. Its modular design facilitates maintenance. Natural gas heaters rely on burners to achieve efficient fuel combustion, and the burner's performance (such as flame stability, control ratio, and emission levels) directly determines the heater's energy efficiency, temperature uniformity, and environmental performance. The main purpose of using windproof devices on the burners in natural gas heaters is to prevent external wind from interfering with the combustion process, ensuring flame stability and combustion efficiency. These windproof devices are usually installed around the burner's flame nozzle, directly blocking the influence of external wind on the flame.

[0003] Traditional windproof devices for furnace burners generally suffer from the following drawbacks: their windproof covers are usually fixed structures, which cannot flexibly adjust the coverage area according to actual working conditions, making it easy for external airflow to interfere with flame stability, especially when wind speed changes or equipment position is adjusted, it is difficult to effectively shield against disturbances; the connection between the windproof cover and the shell mostly relies on welding or complex bolt fixing, which makes installation and disassembly cumbersome and difficult to repeatedly adjust the position, and maintenance requires a lot of time and manpower. Therefore, we propose a windproof device for furnace burners. Summary of the Invention

[0004] The purpose of this invention is to provide a windproof device for the burner of a heating furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A windproof device for a heating furnace burner includes a housing, a nozzle installed at the front port of the housing, a windproof cover housing provided on the outer arm of the housing near the front port, a high-temperature resistant layer provided inside the windproof cover housing, and a connecting component provided between the windproof cover housing and the housing.

[0007] The connecting assembly includes multiple symmetrically distributed mounting limiting grooves around the outer surface of the housing. The front end of the mounting limiting groove penetrates the port of the housing. The windproof cover housing has a corresponding mounting limiting slider inside the housing that matches the groove.

[0008] As a preferred embodiment of this utility model, the windproof cover shell is made of heat-resistant cast steel to improve the structural strength and high-temperature resistance of the windproof cover.

[0009] The technical effect of adopting the above-mentioned further solutions is that heat-resistant cast steel has good high-temperature stability and mechanical strength, which can effectively resist thermal deformation and mechanical impact in the working environment of the heating furnace and extend the service life of the windproof cover.

[0010] As a preferred embodiment of this utility model, the high-temperature resistant layer is made of refractory ceramic fiber material, which is used to enhance the heat insulation effect and prevent the influence of high-temperature heat radiation on the windproof cover shell.

[0011] The technical effects of adopting the above-mentioned further solutions are: refractory ceramic fiber materials have excellent heat insulation and high temperature resistance, which can effectively block the high temperature heat radiation generated by the burner, reduce the heating temperature of the windproof cover shell, avoid damage to the shell due to overheating, and at the same time improve energy utilization efficiency and reduce heat loss.

[0012] As a preferred embodiment of this utility model, threaded holes are provided on all four sides of the outer surface of the windproof cover housing, and the threaded holes penetrate the bottom of the mounting limit slider.

[0013] As a preferred embodiment of this utility model, each of the threaded holes is threaded with a fixing bolt.

[0014] As a preferred embodiment of this utility model, a handle is connected to one top end of the fixing bolt, and an abutment block is connected to one bottom end of the fixing bolt.

[0015] As a preferred embodiment of this utility model, the outer surface of the windproof cover housing is provided with a plurality of heat dissipation fins.

[0016] As a preferred embodiment of this invention, the heat sink is made of aluminum alloy to enhance heat dissipation and reduce the overall structural weight.

[0017] The technical effect of adopting the above-mentioned further solution is that aluminum alloy material has excellent thermal conductivity and lightweight characteristics, which can quickly conduct heat from the surface of the windshield shell to the outside. By increasing the contact area with the outside air, the heat dissipation efficiency is improved, thereby effectively reducing the temperature of the windshield shell and avoiding the impact of overheating on its structural stability and service life.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this invention, the design of the windproof cover effectively blocks external airflow, preventing it from interfering with the burner flame, ensuring stable flame combustion, and avoiding flame extinguishing or uneven combustion caused by airflow fluctuations. With the cooperation of the connecting components, the windproof cover can be flexibly adjusted along the direction of the installation limit slide groove to cover the nozzle position. During operation, simply loosening the fixing bolts is enough to push the windproof cover to the target position and then re-locking it, achieving rapid adjustment to meet the windproof requirements under different working conditions. It is also easy to install and disassemble quickly, with a simple and quick operation process, and reduced maintenance intensity. Attached Figure Description

[0029] As shown in Figures 1-4, this utility model provides a technical solution: a windproof device for a heating furnace burner. The device includes a housing 1, with a nozzle 101 installed at the front port of the housing 1. A windproof cover housing 2 is provided on the outer arm of the housing 1 near the front port. The windproof cover housing 2 effectively blocks external airflow, preventing interference with the burner flame, ensuring stable flame combustion, and avoiding flame extinguishing or uneven combustion caused by airflow fluctuations. A connecting component 3 is provided between the windproof cover housing 2 and the housing 1. The connecting component 3 includes multiple symmetrically distributed mounting limiting grooves 301 on the outer surface of the housing 1. The front end of the mounting limiting groove 301 penetrates the port of the housing 1. A mounting limiting slider 302 matching the groove is provided at a corresponding position inside the windproof cover housing 2. Threaded holes 4 are provided on all four sides of the outer surface of the windproof cover housing 2, penetrating the bottom of the mounting limiting slider 302. All threaded holes 4 are threaded connections. A fixing bolt 303 is provided, with a handle 3031 connected to one top end and an abutment block 3032 connected to one bottom end. The windproof cover housing 2 is aligned with the mounting limiting slider 302 inside the housing 1 and the mounting limiting groove 301 on the outer surface of the housing 1. The windproof cover housing 2 is pushed in along the groove until it completely covers the nozzle 101 at the front port of the housing 1. The fixing bolt 303 is then screwed in through the threaded holes 4 around the outer surface of the windproof cover housing 2, ensuring that the abutment block 3032 is in close contact with the bottom of the mounting limiting groove 301 on the surface of the housing 1, thus ensuring a stable installation of the windproof cover housing 2.

The position of the windproof cover housing 2 can be adjusted as needed. The overall installation and disassembly process is simple and quick, facilitating daily maintenance and repair, and reducing maintenance costs and workload. Example 2

[0030] As shown in Figures 1-4, this utility model provides a technical solution: a windproof device for a heating furnace burner. The windproof cover shell 2 has a high-temperature resistant layer 201 inside. The windproof cover shell 2 is made of heat-resistant cast steel, which has good high-temperature stability and mechanical strength, effectively resisting thermal deformation and mechanical impact under the working environment of the heating furnace, extending the service life of the windproof cover. The high-temperature resistant layer 201 is made of refractory ceramic fiber material, which has excellent heat insulation and high-temperature resistance, effectively blocking the high-temperature heat radiation generated by the burner, reducing the heating temperature of the windproof cover shell 2, preventing damage to the shell 1 due to overheating, and improving energy utilization efficiency while reducing heat loss. The heat sink 5 is made of aluminum alloy to enhance heat dissipation and reduce the overall structural weight. Aluminum alloy has excellent thermal conductivity and lightweight characteristics, enabling it to quickly conduct heat from the surface of the windproof cover shell 2 to the outside. By increasing the contact area with the outside air, heat dissipation efficiency is improved, thereby effectively reducing the temperature of the windproof cover shell 2 and preventing overheating from affecting its structural stability and service life.

[0031] The working process of this utility model is as follows: When using a windproof device for a heating furnace burner, first align the installation limiting slider 302 inside the windproof cover housing 2 with the installation limiting grooves 301 symmetrically distributed around the outer surface of the housing 1. Push the windproof cover housing 2 along the direction of the installation limiting grooves 301 until it completely covers the nozzle 101 at the front end of the housing 1. Then, screw in the fixing bolts 303 through the threaded holes 4 around the outer surface of the windproof cover housing 2. One end of the fixing bolt 303 is connected to a handle 3031, and one end of the fixing bolt 303 is connected to an abutment block 3032. By rotating the handle 3031, the fixing bolt 303 is driven to move downward, so that the abutment block 3032 at the bottom tightly abuts against the bottom of the installation limiting groove 301. The windproof cover housing 2 is securely connected to the housing 1 using the axial pressure of bolts. Simultaneously, with the cooperation of the installation limiting groove 301 and the installation limiting slider 302, the position of the windproof cover can be adjusted as needed. This can be done by reversing the operation: loosening the fixing bolt 303, moving the windproof cover housing 2 along the groove to the target position, and then tightening the bolt again, thus quickly completing the position fine-tuning to adapt to different working conditions. The windproof cover housing 2 is made of heat-resistant cast steel, with an internal composite refractory ceramic fiber high-temperature resistant layer 201, which can block high-temperature heat radiation from the burner and resist thermal deformation. Combined with the lightweight design of the external aluminum alloy heat sink 5, it rapidly dissipates heat in high-temperature environments by increasing the heat dissipation area, ensuring structural stability and the reliability of adjustable operation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
