Description

Technical Field

[0001] This utility model belongs to the field of boiler technology, and in particular relates to a high-efficiency combustion-supporting air distribution mechanism for biomass boilers. Background Technology

[0002] In the biomass boiler industry, efficient combustion air distribution is crucial for improving combustion efficiency, reducing energy consumption, and minimizing pollutant emissions. Traditional combustion air distribution mechanisms for biomass boilers have long been used in this field, and to a certain extent, they can meet the basic combustion air distribution requirements of biomass boilers and maintain their normal operation.

[0003] A thorough analysis of the structure and function reveals numerous shortcomings in the combustion air distribution mechanisms of traditional biomass boilers. Regarding air uniformity, traditional mechanisms often lack the ability to distribute air evenly, failing to ensure uniform delivery of combustion air into the boiler. This results in uneven combustion within the boiler, with some areas experiencing incomplete combustion. This not only reduces combustion efficiency but may also increase the emission of incomplete combustion products, placing greater pressure on the environment. In terms of air purification, traditional mechanisms lack dust removal capabilities, failing to effectively remove dust and other impurities from the air. These impurities, once inside the boiler, not only affect combustion performance but, over time, can damage internal components, shorten the boiler's lifespan, and increase maintenance costs.

[0004] To address these issues, we have developed a high-efficiency combustion-supporting air distribution mechanism for biomass boilers. Utility Model Content

One side of the high-power industrial fan 4 is connected to the dust collection box 5. The uniform air outlet mechanism 3 includes springs 31 fixed to both sides of the inner cavity of the shell 2, an air outlet hood 32 fixedly connected to one end of the springs 31, a sliding groove 33 fixedly connected to one side of the air outlet hood 32, an elliptical plate 34 slidably connected to the inner wall of the sliding groove 33, a vertical plate 35 fixedly connected to the inner wall of the shell 2, a rotating rod 36 movably connected to the surface of the vertical plate 35 through a bearing, one end of the rotating rod 36 fixedly connected to the elliptical plate 34, and the other end of the rotating rod 36 fixedly connected to a worm gear 37, a motor 38 fixedly connected to the top of the shell 2, and a worm 39 that works with the worm gear 37 fixedly connected to the output end of the motor 38.

[0028] Specifically, the uniform air outlet mechanism 3 utilizes the motor 38 to drive the elliptical plate 34 in conjunction with the spring 31 and the air outlet hood 32, thereby achieving uniform output of combustion air and significantly improving the combustion efficiency of the biomass boiler. At the same time, the dust collector 5 can effectively filter dust in the air, reduce dust damage to the internal components of the boiler, extend the service life of the boiler, and improve the stability and environmental friendliness of the boiler operation.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, a horizontal pipe 401 is connected to the other side of the high-power industrial fan 4. One end of the horizontal pipe 401 extends into the inner cavity of the housing 2 and is connected to a corrugated pipe 402. The end of the corrugated pipe 402 away from the horizontal pipe 401 is connected to the air outlet hood 32. A fixing frame is fixedly connected to the top of the base plate 1. The top of the fixing frame is fixedly connected to the bottom of the high-power industrial fan 4. The top of the dust collector 5 away from the high-power industrial fan 4 has evenly distributed air inlet slots. A cleaning plate is fixedly connected to the bottom of the dust collector 5 away from the high-power industrial fan 4 by bolts. A sealing plate 501 is provided on the top of the dust collector 5. A filter element 502 is fixedly connected to the bottom of the sealing plate 501. The bottom of the filter element 502 extends... At the bottom of the inner cavity of the dust collector 5, a fixing member 503 is provided between the sealing plate 501 and the dust collector 5. The fixing member 503 includes a first support plate and a second support plate. One side of the first support plate is fixedly connected to the sealing plate 501, and one side of the second support plate is fixedly connected to the dust collector 5. A fixing bolt is provided through the top of the first support plate, and the threaded end of the fixing bolt passes through to the bottom of the second support plate and is threadedly connected to a fixing nut. A slot is provided at the bottom of the filter element 502, and an insert plate 504 is provided in the inner cavity of the slot. The bottom of the insert plate 504 is fixedly connected to the bottom of the inner cavity of the dust collector 5. A mounting plate 6 is fixedly connected to the side of the housing 2 away from the high-power industrial fan 4. Mounting holes are symmetrically provided on the surface of the mounting plate 6.

[0031] Specifically: The horizontal pipe 401 and the corrugated pipe 402 ensure that the air generated by the high-power industrial fan 4 can be stably and smoothly delivered to the air outlet hood 32. The horizontal pipe 401 provides a stable air duct connection, while the corrugated pipe 402, while ensuring the connection seal, can adapt to the reciprocating motion of the air outlet hood 32, avoiding airflow loss or leakage due to pipe connection problems. The mounting bracket firmly fixes the high-power industrial fan 4 to the base plate 1, providing stable support for the fan. The air inlet slots are evenly distributed on the top of the dust collector 5, ensuring that the air contains... Dust-laden air can enter the dust collection chamber 5 evenly, allowing the filter element 502 to fully perform its filtering function and improving dust removal efficiency. The cleaning plate is fixed to the bottom of the dust collection chamber 5 with bolts. This design makes cleaning the dust accumulated on the filter element 502 very convenient. When cleaning is required, simply unscrew the bolts and remove the cleaning plate to clean the dust from the filter element 502 and the inner cavity of the dust collection chamber 5. The combined design of the sealing plate 501, filter element 502, and fixing component 503 ensures that the filter element 502 is firmly installed and well-sealed inside the dust collection chamber 5. The sealing plate 501 ensures the airtightness of the dust collector 5, preventing unfiltered air leakage; the filter element 502 effectively filters dust from the air; the fastener 503 firmly connects the sealing plate 501 to the dust collector 5, ensuring that the filter element 502 will not loosen during long-term use. The fastener 503 adopts a structure of a first support plate, a second support plate, fixing bolts, and fixing nuts, which is simple and practical. This structure allows for convenient and quick fixation of the sealing plate 501 to the dust collector 5, and also facilitates easy operation when the filter element 502 needs to be disassembled for maintenance or replacement. The slot at the bottom of the filter element 502 cooperates with the insertion plate 504, further enhancing the stability of the filter element 502 installation. The insertion plate 504 is inserted into the slot, making the position of the filter element 502 more stable in the dust collector 5, and less prone to displacement due to vibration or other external forces. The mounting plate 6 and mounting holes greatly improve the convenience and flexibility of the entire combustion air distribution mechanism installation. Through the mounting plate 6 and mounting holes, the mechanism can be easily installed and fixed in various suitable positions.

[0032] The working principle of this utility model is as follows: A high-power industrial fan 4 sends air into a dust collector 5. After being filtered by the dust collector 5, the air is then transported to a uniform air outlet mechanism 3 inside the housing 2, ultimately providing uniform combustion air to the biomass boiler. The motor 38 at the top of the housing 2 is started, and the output end of the motor 38 drives the worm gear 39 to rotate. Since the worm gear 39 and the worm wheel 37 mesh with each other, the worm wheel 37 rotates accordingly, thereby driving the rotating rod 36 connected to it to rotate on the bearing on the surface of the vertical plate 35. The elliptical plate 34 fixed at one end of the rotating rod 36 slides in the groove 33 on the opposite side of the air outlet hood 32. As the elliptical plate 34 rotates, it pushes the air outlet hood 32 within the housing. 2. Under the elastic action of the springs 31 on both sides of the inner cavity, the air reciprocates. The air generated by the high-power industrial fan 4 enters the air outlet hood 32 through the horizontal pipe 401 and the corrugated pipe 402. During the reciprocating motion of the air outlet hood 32, uniform air is achieved, providing stable and uniform combustion air for the biomass boiler. The high-power industrial fan 4 delivers the dust-containing air to the dust collector 5. The dust collector 5 has evenly distributed air inlet slots on the top side away from the fan, so that the air can enter the dust collector 5 evenly. The air is filtered by the filter element 502 in the dust collector 5, and the dust is intercepted by the filter element 502. The purified air is delivered from the other side of the dust collector 5 to the shell 2 for combustion air distribution.
