Description

Technical Field

[0001] This utility model relates to the field of boilers, specifically a boiler with an air control mechanism. Background Technology

[0002] In industrial production and daily life, boilers are an important thermal energy equipment, widely used in many fields such as heating, power generation, and industrial heating. The combustion efficiency and operational stability of boilers directly affect energy consumption, operating costs, and production safety. Air volume control and air supply during the combustion process are among the key factors that determine the combustion performance of boilers.

[0003] Currently, traditional boilers generally suffer from insufficient air volume regulation precision during combustion. Most boilers have relatively simple air intake structures, making it difficult to accurately regulate the air volume based on the actual combustion conditions inside the combustion chamber. This often results in situations where excessive air volume leads to incomplete fuel combustion and wasted heat energy, or insufficient air volume causes incomplete combustion and the generation of harmful gases, seriously affecting the boiler's combustion efficiency and environmental performance.

[0004] Meanwhile, in terms of air supply, traditional boilers often lack effective air pretreatment measures. When external air enters the boiler, dust, impurities, and other contaminants it contains can easily enter the equipment. Long-term accumulation may cause pipe blockage, component wear, and reduce the service life and operational reliability of the equipment. Moreover, the air entering the boiler has poor mixing uniformity, and the air and fuel cannot fully contact each other, which further restricts the improvement of combustion efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a boiler with an air control mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a boiler with a wind control mechanism, including a boiler and a burner. The burner is fixed to the back of the boiler. A first wind box is fixed to one side wall of the burner. A wind vane is rotatably connected inside the first wind box. An adjusting component is fixed to one end of the wind vane that passes through the first wind box. A driving component is fixed to the adjusting component. Two air inlet pipes are inserted into the right side of the boiler. A second wind box is fixed to the outer wall of the boiler on one side of the air inlet pipe. A connecting pipe is fixed to the center of the outer wall of the second wind box. An air supply device is provided inside the connecting pipe.

[0007] Furthermore, the inner wall of the air inlet duct is fixed with multiple baffle rods, the shape of which can be cylindrical or conical.

[0008] Furthermore, the air supply device includes two impellers, which are rotatably connected inside the connecting pipe and mesh with each other. The bottom shaft of each impeller passes through the connecting pipe, and a gear is fixed to the end face of the bottom shaft. The gears on both sides are in contact with each other. The top shaft of one impeller passes through the connecting pipe, and a driver is fixed to the end face of the top shaft.

[0009] Furthermore, a filter screen is fixed to the end face of the connecting pipe away from the second air box.

[0010] Furthermore, a support plate is fixed to one side of the outer wall of the adjusting component, and the support plate has a hollow interior with a strip-shaped groove.

[0011] Furthermore, the driving component includes a hydraulic cylinder, which is fixed above the first air box near the adjusting component. A slider is fixed to the output end of the hydraulic cylinder, and the slider is slidably connected to the adjusting component.

[0012] Furthermore, a gear protective cover is fixed to the bottom end of the connecting pipe on the outside of the gear.

[0013] The beneficial effects of this utility model are:

[0014] Air control improves combustion efficiency: Through the cooperation of the rotatable air vane, adjustment components, and drive components in the first air box, the air intake near the burner can be precisely adjusted to meet the air volume requirements of different combustion stages. At the same time, the second air box and air supply device stably deliver the air required for combustion inside the boiler. The synergistic effect of the dual air supply paths effectively optimizes the air supply in the combustion chamber, promotes complete fuel combustion, and improves the thermal efficiency of the boiler.

[0015] Air pretreatment: The filter screen at the end of the connecting pipe can filter dust and impurities in the air, preventing them from entering the equipment and causing blockage or damage, thus ensuring the cleanliness of the air entering the boiler. Multiple baffles on the inner wall of the air inlet pipe can turbulentize the air, allowing the air to mix fully in the air inlet pipe. Among them, the cylindrical rods provide uniform and stable turbulence, while the conical rods have a stronger turbulence effect and can reduce wind resistance, further improving the mixing effect of air and fuel, which is conducive to the full combustion reaction.

[0016] Structural design: The two meshing impellers in the air supply device achieve synchronous counter-rotation, which improves the air supply efficiency and provides sufficient power for air delivery. The first and second air boxes respectively play the roles of concentrating the airflow and buffering the initial collection of incoming air, thus optimizing the air path design and improving the overall performance of the equipment.

[0023] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0024] See Figures 1-5 This is a schematic diagram of the structure of this utility model. A boiler with a wind control mechanism includes a boiler 1, a combustion chamber 2, an observation window 3, and a burner 4. The combustion chamber 2 is fixed inside the boiler. The combustion chamber 2 is the core area for fuel combustion and is made of high-temperature resistant material to withstand the high-temperature combustion environment. The burner 4 is fixed to the back of the boiler 1. The burner 4 is used to ignite the fuel and maintain the combustion state. The observation window 3 is fixed inside the front surface of the boiler 1. The observation window 3 is made of high-temperature resistant transparent glass material, which allows the operator to observe the combustion situation inside the combustion chamber 2 in real time. The observation window 3 is fixedly connected to the combustion chamber 2.

[0025] A first air box 5 is fixed on one side wall of the burner 4. The first air box 5 serves to concentrate and guide the airflow. An air vane 6 is rotatably connected inside the first air box 5. The air vane 6 can adjust the air intake by changing its angle through rotation. An adjusting member 7 is fixed at one end of the air vane 6 that passes through the first air box 5. The adjusting member 7 is used to drive the air vane 6 to adjust its angle. A driving member is fixed on the adjusting member 7. The driving member is used to drive the adjusting member 7 to rotate. Two air inlet pipes 9 are inserted into the right side of the boiler 1. The air inlet pipes 9 supply the air required for combustion inside the boiler. A second air box 11 is fixed on the outer wall of the boiler 1 on one side of the air inlet pipes 9. The second air box 11 can initially collect and buffer the incoming air. A connecting pipe 12 is fixed at the center of the outer wall of the second air box 11. The connecting pipe 12 is used to introduce external air into the second air box 11. An air supply device is installed inside the connecting pipe 12. The air supply device provides power for air supply.

[0026] Multiple baffle rods 10 are fixed on the inner wall of the air inlet duct 9. The baffle rods 10 can turbulent the incoming air, so that the air is fully mixed in the air inlet duct 9. The shape of the baffle rods 10 can be cylindrical or conical. Cylindrical rods provide uniform and stable turbulence, while conical rods have a stronger turbulence effect and can reduce wind resistance.

[0027] The air supply device includes two impellers 14, which are rotatably connected inside the connecting pipe 12. The impellers generate air supply power through rotation. The two impellers 14 mesh with each other and can rotate synchronously in opposite directions to improve air supply efficiency. The bottom shaft of the impeller 14 passes through the connecting pipe 12, and a gear 16 is fixed to the end face of the bottom shaft. The gear 16 plays a transmission role. The gears 16 on both sides are in contact to ensure stable power transmission. The top shaft of one impeller 14 passes through the connecting pipe 12, and a driver 15 is fixed to the end face of the top shaft. The driver 15 provides power output for the rotation of the impeller.

[0028] A filter screen 13 is fixed to the end face of the connecting pipe 12 away from the second air box 11. The filter screen 13 is made of fine metal mesh material, which can filter dust, impurities and other substances in the air to prevent them from entering the equipment and causing blockage or damage.

[0029] A support plate is fixed to one side of the outer wall of the adjusting component 7. The support plate has a hollow interior with a strip-shaped slot. The driving component includes a hydraulic cylinder 8, which serves as a power source and can provide a stable linear driving force. The hydraulic cylinder 8 is fixed above the first air box 5 near the adjusting component 7. A slider is fixed to the output end of the hydraulic cylinder 8. The slider is slidably connected to the adjusting component 7. The adjusting component 7 is rotated by sliding the slider on the adjusting component 7.

[0030] The bottom end of the connecting pipe 12 is fixed with a gear protective cover on the outside of the gear 16. The protective cover is made of metal and can effectively prevent dust, moisture and other substances from entering the gear 16.

[0031] When using this utility model:

[0032] During operation, the boiler with the air control mechanism ignites the fuel in the combustion start-up phase. The flame burns continuously within the combustion chamber 2. Operators can monitor the combustion status in the combustion chamber 2 in real time through the observation window 3 made of high-temperature resistant transparent glass. The air required for combustion enters the boiler 1 through a dual air supply path. External air enters through the connecting pipe 12, where the filter screen 13 at the end of the connecting pipe 12 first filters the air, removing dust and impurities. Then, the driver 15 drives one side impeller 14 to rotate. Since the two impellers 14 mesh and the bottom shaft is driven by the gear 16, the two impellers 14 rotate synchronously in opposite directions, generating air supply power to send air into the second air supply system. The second air box 11 collects and buffers the air before introducing it into the right side of the boiler 1 through two air inlet pipes 9. Multiple cylindrical or conical baffles 10 on the inner wall of the air inlet pipes 9 create turbulence in the airflow, ensuring thorough mixing of the air to improve subsequent combustion efficiency. The first air box 5 is responsible for supplementing air near the burner 4. Air volume control is achieved through the cooperation of the adjusting component 7 and the driving component. Specifically, the hydraulic cylinder 8 acts as the driving component, outputting linear power. The slider at its end slides on the adjusting component 7, causing the air vane 6 to rotate inside the first air box 5. The air volume is adjusted by changing the angle of the air vane 6. The hollow support plate on the outer wall of the adjusting component 7 can assist in fixing or threading pipelines to ensure stable adjustment.
