Description

Technical Field

[0001] The utility model relates to the technical field of biomass boilers, in particular to a rotating air guide device for a biomass boiler. Background Art

[0002] A biomass boiler is a type of boiler that uses biomass energy (such as wood chips, straw and other agricultural and forestry waste) as fuel for heating or power generation. According to different classification standards, biomass boilers can be divided into many types, such as biomass steam boilers, biomass hot water boilers, biomass hot air furnaces, biomass thermal oil furnaces, etc., as well as horizontal biomass boilers and vertical biomass boilers.

[0003] Biomass boilers are usually equipped with an air blowing system, which plays a significant role in improving the combustion efficiency of biomass fuel, optimizing the combustion process and reducing pollutant emissions. However, the existing air blowing system can only blow air into the boiler in a certain direction. Therefore, the air volume in the middle of the air inlet is greater than the air volume around it. The air entering the boiler is uneven, resulting in the air being unable to evenly penetrate the biomass fuel layer, which means that it cannot promote the full combustion of the fuel. Utility Model Content

[0004] In order to make up for the deficiencies of the existing technical problems, the purpose of the utility model is to provide an air guide assembly whose air guide box rotates to drive the air guide port above to rotate, solving the problem of uneven air entering the boiler because the air volume in the middle of the air inlet is greater than the air volume around it.

[0005] In order to solve the problems of the existing technology, the technical solution of the present invention is as follows: a rotating air guide device for a biomass boiler includes a boiler body, which is the main part of the biomass boiler and is used to accommodate burning biomass and perform heat exchange. A support plate is fixed on one side of the boiler body and is used to support a blower. The blower is fixed next to the boiler body through the support plate and is responsible for sending external air into the boiler. A vent is opened on one side of the boiler body and is connected to the air outlet of the blower, allowing the air blown by the blower to enter the boiler; an air guide assembly connected to the boiler body is used to evenly disperse the air entering the vent in the boiler body; a heating assembly respectively connected to the boiler body and the blower is used to heat the air entering the boiler body.

[0006] Preferably, the air guide assembly includes a rotating tube rotatably connected to the inner wall of the boiler body, and an air guide box is fixedly connected to one end of the rotating tube for receiving and dispersing the wind from the rotating tube. The air guide port is opened on one side of the air guide box, and there are multiple air guide ports that are evenly distributed to ensure that the wind can be evenly dispersed into the interior of the boiler.

[0007] Preferably, the rotating gear and the transmission gear are driven by the motor to rotate the transmission shaft, and the transmission gear on the transmission shaft is engaged with the rotating gear on the outer wall of the rotating tube, driving the rotating tube to rotate, thereby realizing the rotating air guiding effect of the air guide box. The motor is fixed on one side of the boiler body, and one end of the motor output shaft is fixedly connected to one end of the transmission shaft through a coupling to provide power for the rotating tube.

[0008] Preferably, the heating assembly includes a recovery pipe fixedly connected to the outer wall of the boiler body, which is used to recover the high-temperature flue gas or heat energy in the boiler. One end of the connecting pipe is connected to the recovery pipe, and the other end is connected to the air inlet of the blower. The air entering the boiler is preheated by the recovered high-temperature flue gas or heat energy, thereby improving the heating efficiency. The air inlet pipe serves as an extension of the blower air inlet and is connected to the connecting pipe to ensure that the preheated air can smoothly enter the blower and be sent to the boiler.

[0009] Compared with the prior art, the advantages of the present invention are as follows:

[0010] The utility model provides an air guide assembly, a starting motor drives the transmission gear to rotate, the transmission gear drives the rotating gear to rotate, the rotating gear drives the rotating tube to rotate, the rotating tube drives the air guide box to rotate, and the hot air entering the air guide box enters the boiler body through multiple air guide ports. At the same time, the rotation of the air guide box drives the upper air guide ports to rotate, thereby avoiding the situation where the air volume in the middle of the air inlet is greater than the air volume around it, and the air entering the boiler is uneven, so that the air can penetrate the biomass fuel layer more evenly, thereby promoting the full combustion of the fuel.

[0011] The utility model provides a heating component, and the hot air flow in the biomass boiler enters the connecting pipe through the recovery pipe, and then enters the air inlet pipe through the connecting pipe. The blower is started, and the blower draws hot air through the air inlet pipe, and then the hot air enters the rotating pipe through the vent, and then enters the air guide box, so that part of the flue gas can be mixed with fresh air and then sent into the boiler body, and the waste heat of the flue gas is used to preheat the air. The combustion temperature is increased by preheating the air, which is conducive to the rapid ignition and full combustion of the fuel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figure 1-4 The rotary air guide device of the biomass boiler includes a boiler body 1. The boiler body 1 is the main structure of the biomass boiler. It accommodates all components for burning biomass and performing heat exchange. The boiler body 1 provides sufficient space and conditions to enable the biomass to be fully burned and release heat energy. The support plate 2 is fixed to one side of the boiler body 1. Its main function is to support the blower 3 and ensure that the blower 3 can operate stably. Through the support plate 2, the blower 3 can be firmly installed next to the boiler body 1, thereby conveniently sending external air into the boiler. The blower 3 is connected to an external power supply and is one of the core components in the rotary air guide device. It is responsible for sending fresh air from the outside into the boiler. Through the action of the blower 3, sufficient oxygen can be obtained in the boiler to support the full combustion of biomass. The air volume and pressure of the blower 3 can be controlled by adjustment to achieve stable and efficient combustion in the furnace. The vent 4 is opened on one side of the boiler body 1 and is connected to the air outlet of the blower 3. It allows the air blown by the blower 3 to smoothly enter the boiler and provide the necessary oxygen for the combustion process.

[0019] See also Figure 3-4The air guide assembly includes components such as a rotating tube 5, an air guide box 6 and an air guide port 7. Its main function is to evenly disperse the air entering from the vent 4 in the boiler body 1. Through the rotation of the rotating tube 5 and the air guide box 6, the air is evenly distributed to all corners of the boiler, avoiding the problem of local overheating or uneven temperature. The design of the air guide port 7 allows the air to enter the boiler at an appropriate angle and speed, further improving the uniformity of the air distribution. The rotating tube 5 is rotatably connected to the inner wall of the boiler body 1. Its rotation is driven by a motor 11 through a transmission shaft 9 and a gear. The air guide box 6 is fixedly connected to one end of the rotating tube 5 and rotates as the rotating tube 5 rotates. The synergistic effect of the rotating tube 5 and the air guide box 6 achieves the function of uniform dispersion and guidance of the air. The motor 11 is fixed to one side of the boiler body 1 and is connected to the transmission shaft 9 through a coupling. The motor 11 provides power to drive the transmission shaft 9 to rotate, thereby driving the rotating tube 5 and the air guide box 6 to rotate. The transmission mechanism (including the transmission shaft 9, the transmission gear 10 and the rotating gear 8) ensures the effective transmission of the power of the motor 11 and the smooth progress of the rotational motion.

[0020] See also Figure 1-2 The heating assembly includes components such as a recovery pipe 12, a connecting pipe 13 and an air inlet pipe 14. Its main function is to use the high-temperature flue gas or heat energy in the boiler to preheat the air entering the boiler. The recovery pipe 12 is fixedly connected to the outer wall of the boiler body 1 for recovering high-temperature flue gas or heat energy. The connecting pipe 13 introduces the recovered high-temperature flue gas or heat energy into the air inlet of the blower 3. The air inlet pipe 14 serves as an extension of the air inlet of the blower 3, and sends the preheated air into the blower 3 and finally into the boiler. Through the action of the heating assembly, the temperature of the air entering the boiler is increased, thereby improving the heating efficiency and heat energy utilization rate of the boiler.

[0021] During use, the hot air flow in the biomass boiler enters the connecting pipe 13 through the recovery pipe 12, and then enters the air inlet pipe 14 through the connecting pipe 13, and starts the blower 3. The blower 3 draws in hot air through the air inlet pipe 14, and then the hot air enters the rotating tube 5 through the vent 4, and then enters the air guide box 6. The motor 11 is started, and the motor 11 drives the transmission shaft 9 to rotate, and the transmission shaft 9 drives the transmission gear 10 to rotate, and the transmission gear 10 drives the rotating gear 8 to rotate, and the rotating gear 8 drives the rotating tube 5 to rotate, and the rotating tube 5 drives the air guide box 6 to rotate. The hot air entering the air guide box 6 enters the boiler body 1 through multiple air guide ports 7. At the same time, the rotation of the air guide box 6 drives the upper air guide port 7 to rotate, so that the hot air is evenly blown into the boiler.
