Description

Technical Field

[0001] This utility model relates to the field of biomass combustion equipment technology, and more specifically, to a temperature control and energy-saving component for a biomass burner. Background Technology

[0002] With the adjustment of energy structure and the increasing environmental protection requirements, biomass burners, as a type of equipment that uses biomass fuels (such as straw, wood chips, etc.) for combustion and heating, have been widely used due to their advantages such as being renewable and environmentally friendly. However, existing biomass burners have some problems in use, such as the inability to effectively recover and utilize the heat generated during combustion, which further reduces energy efficiency.

[0003] Utility model patent CN219389812U discloses an ignition device for an environmentally friendly biomass boiler, including a base. A controller is fixedly mounted on the top of the base, and a biomass boiler assembly is located on the top of the base. The biomass boiler assembly includes a main body, and an insulation layer is fixedly mounted on the inner wall of the main body. This environmentally friendly biomass boiler ignition device, through a signal emitted by the controller, starts a motor connected to the inner wall of a connecting column, causing a pressure plate to rotate and compress the biomass pellets on the inner wall of the front smoke box. This prevents the biomass pellets from accumulating on the inner wall of the front smoke box. The ventilation slots allow for sufficient contact between oxygen in the air and the biomass pellets, ensuring complete combustion. The controller then starts the burner, completing the ignition of the device. This accelerates the ignition speed, reduces biomass pellet loss, improves combustion efficiency, and saves on biomass pellet waste, thereby achieving the goal of environmental protection and energy conservation.

[0004] While this technical solution reduces biomass pellet waste and achieves environmental protection and energy conservation goals, this type of biomass burner still has some shortcomings in practical use. Relying on ventilation slots to ensure sufficient contact between the material and oxygen for more complete combustion still results in some drawbacks. First, the size of the ventilation slots cannot be adjusted, thus limiting the air intake. This makes it difficult to control the temperature by adjusting the flame size within the combustion chamber. Furthermore, if the biomass pellets continue to burn at the corresponding rate, a significant amount of biomass pellets will be consumed, hindering the achievement of temperature control and energy conservation. Therefore, we propose a temperature control and energy-saving component for biomass burners. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 This utility model provides a technical solution: a temperature control and energy-saving component for a biomass burner, including a biomass burner body 1 and a combustion chamber 10 disposed on the biomass burner body 1. An air intake regulating component 3 for adjusting the amount of incoming air is disposed on the combustion chamber 10. The air intake regulating component 3 includes a ventilation pipe 30 fixedly installed on the side plate of the combustion chamber 10. An internal pipe 31 is fixedly installed at the inner end of the ventilation pipe 30, and a first heat insulation collar 32 is fixedly installed at the outer end of the ventilation pipe 30. The end flange of the first heat insulation collar 32 is connected to a heat exchanger. The end flange of the thermal compensation pipe 33 is connected to a second thermal insulation collar 34. An electric butterfly valve 35 is fixedly installed at the end of the second thermal insulation collar 34. An air intake hood 36 is connected to the end flange of the electric butterfly valve 35. A fan 37 for air intake is provided at the end of the air intake hood 36. The electric butterfly valve 35 can flexibly change its opening degree and precisely adjust the air intake of the ventilation pipe 30 so that the amount of air entering the combustion chamber 10 can match the combustion requirements, thereby effectively controlling the combustion intensity and temperature, avoiding fuel waste due to improper air intake, and achieving efficient temperature control and energy saving.

[0031] like Figure 4 As shown, a blower pipe 371 is fixedly installed at the air outlet end of the blower 37. The end flange of the blower pipe 371 is connected to the air inlet hood 36, which facilitates fixing, installation and disassembly operations.

[0032] like Figure 1 and Figure 2 As shown, a feed hopper 11 is fixedly installed on the top of the combustion chamber 10. The inner wall of the feed hopper 11 is inclined downward at 45°~60°, so that biomass fuel can slide more smoothly from the feed hopper 11 into the combustion chamber 10 by its own gravity and the inclination angle, reducing the accumulation and blockage of materials in the feed hopper 11, ensuring the continuity of fuel supply, and thus improving combustion efficiency.

[0033] like Figure 1 As shown, multiple support blocks 12 are fixedly installed at the bottom of the biomass burner body 1. The height of the support blocks 12 is between 8cm and 12cm, which effectively raises the bottom of the equipment and enhances the air circulation at the bottom of the equipment.

[0034] In this embodiment, a side plate 16 is fixedly installed on the top side plate of the feed hopper 11. A sealing assembly 2 for sealing the feed hopper 11 is provided on the top of the feed hopper 11. The sealing assembly 2 includes a servo motor 20 fixedly installed on the bottom surface of the side plate 16. The output shaft end of the servo motor 20 is connected to a sealing cover plate 24 through a connecting rod 23. After the sealing cover plate 24 is closed, it covers the top surface of the feed hopper 11. The lower projection of the sealing cover plate 24 coincides with the lower projection of the feed hopper 11. The sealing cover plate 24 can be used to cover the top position of the feed hopper 11, reducing heat loss and achieving energy saving effect.

[0035] like Figure 5 As shown, a rectangular protrusion 21 is fixedly installed at the end of the output shaft of the servo motor 20, and a rectangular sleeve 22 is fixedly installed at the end of the connecting rod 23. The rectangular sleeve 22 is fitted onto the rectangular protrusion 21 and is fixedly connected to the rectangular protrusion 21 by multiple fastening bolts. The rectangular sleeve 22 and the rectangular protrusion 21 are detachably connected, which facilitates fixed installation and disassembly operations.

[0036] Furthermore, an electrical control box 13 is installed on one side of the biomass burner body 1, and a control host 14 is installed inside the electrical control box 13. A temperature sensor 15 is installed on one side of the electrical control box 13. The temperature sensor 15 is placed in the heat exchange pipe inside the biomass burner body 1. The temperature sensor 15 monitors the temperature data in the heat exchange pipe in real time and transmits it to the control host 14. The control host 14 analyzes and processes the data according to a preset program, accurately regulates the equipment operating status, and realizes intelligent temperature control and equipment management. Specifically, the temperature data detected by the temperature sensor 15 is transmitted to the control host 14. Inside, the control host 14 processes the data and determines whether the temperature is too low or too high compared to the set temperature. If the temperature is too low, the control host 14 controls the electric butterfly valve 35 to open wider, and at the same time, the control host 14 controls the fan 37 to increase its speed to achieve rapid air intake, promote rapid combustion of biomass fuel, and achieve rapid heating. If the temperature is too high, the control host 14 controls the electric butterfly valve 35 to close narrower, and at the same time, the control host 14 controls the fan 37 to decrease its speed to achieve slow air intake, further adjusting the size of the combustion flame to achieve temperature control and energy saving.

[0037] Finally, it should be noted that the electric butterfly valve 35, fan 37, control host 14, and temperature sensor 15 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0038] When the temperature control and energy-saving component of the biomass burner of this utility model is in use, the temperature range is preset in the control host 14, the fan 37 is turned on, and the air enters the combustion chamber 10 through the air inlet hood 36, electric butterfly valve 35, heat compensation pipe 33, ventilation pipe 30 and built-in pipe 31. The sealing cover 24 is opened, and the biomass fuel is poured into the feed hopper 11 with the inner wall inclined. The fuel slides into the combustion chamber 10 under the action of gravity for combustion.

[0039] During operation, the temperature sensor 15 monitors the temperature of the heat exchange pipes inside the biomass burner body 1 in real time and transmits the data to the control host 14. If the temperature is lower than the set value, the control host 14 controls the electric butterfly valve 35 to increase the opening and simultaneously increases the speed of the blower 37 to increase the air intake and promote rapid combustion and heating of the fuel. If the temperature is too high, the electric butterfly valve 35 is controlled to close the opening and the speed of the blower 37 is reduced to decrease the air intake and achieve temperature control. At the same time, the servo motor 20 drives the sealing cover plate 24 to close the feed hopper 11 to reduce heat loss.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
