Description

Technical Field

[0001] This utility model relates to the field of biomass combustion furnace technology, specifically to a blowing device for a biomass combustion furnace. Background Technology

[0002] Biomass refers to non-fossil energy and biodegradable organic matter, derived from plants, animals and microorganisms, including products, by-products, residues, wastes of agriculture, forestry and related industries, as well as organic components in non-fossil and biodegradable industrial and biological waste; Biomass combustion furnaces are important equipment that use biomass (such as wood chips, rice husks, straw, etc.) as fuel for thermal energy conversion. They play an important role in industrial and domestic heating, power generation, and other energy needs. In biomass combustion furnaces, blowing air into the furnace plays a crucial role during the combustion process, primarily providing air to support combustion and improve efficiency and stability. An existing blowing system for biomass combustion furnaces (publication number CN214891130U) uses a blower, driven by a motor output, to draw air in through the air inlet. The drawn air then passes through the air inlet pipe and is blown onto the burning biomass by the blower head, thereby increasing the flame intensity, reducing combustion time, and improving efficiency. However, in practice, due to the different properties of various biomasses, if the air velocity or volume cannot be easily adjusted, it will directly affect the completeness of combustion and the emission of flue gas. Therefore, we propose a blowing device for biomass combustion furnaces. Utility Model Content

[0003] The purpose of this utility model is to provide a blower for a biomass combustion furnace to solve the problem mentioned in the background art that, due to the different properties of different biomasses, if it is not convenient to adjust the wind speed or air volume, it will directly affect the completeness of combustion and the emission of flue gas.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a blower for a biomass combustion furnace, comprising a combustion furnace, an air inlet pipe installed on the surface of the combustion furnace, and further comprising an adjustment component and a protective component. The adjustment component is installed inside the air inlet pipe, and the protective component is installed at the air inlet of the air inlet pipe. When in use, the adjustment component adjusts the ventilation area inside the air inlet pipe to control the air volume and wind speed entering the combustion furnace.

[0005] Preferably, the adjusting assembly includes a limiting plate, bolts, and a movable baffle. The movable baffle is inserted into the surface of the air inlet pipe. Limiting plates are provided on both the upper and lower sides of the movable baffle outside the air inlet pipe. Bolts are threaded onto the surface of the limiting plates. The adjusting assembly also includes a scale strip, a pull ring, and a slide bar. The movable baffle has equidistant scale strips on its surface. A pull ring is fixedly connected to the outside of the movable baffle. Slide bars are provided on both sides of the movable baffle. The slide bars are slidably connected to a groove opened on the inner wall of the air inlet pipe.

[0006] Preferably, the protective component includes a roller, a dustproof net, and a support frame. The support frame is fixedly connected to the air inlet of the air inlet pipe. The dustproof net is movably connected inside the support frame via the roller. The protective component also includes a metal block and a magnetic block. The metal block is embedded inside the dustproof net. The metal block is connected in conjunction with the magnetic block embedded at the air inlet of the air inlet pipe. The cross-sectional area of ​​the dustproof net is larger than the cross-sectional area of ​​the air inlet of the air inlet pipe.

[0007] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features a movable baffle inside the air inlet pipe. By adjusting the position of the movable baffle within the air inlet pipe, the ventilation area inside the air inlet pipe can be adjusted, thereby controlling the air volume and velocity entering the combustion furnace. This facilitates the use of different biomass materials. Equidistant scale strips are provided on the surface of the movable baffle, allowing for quick adjustment of the ventilation area inside the air inlet pipe. Additionally, a limiting plate is provided outside the air inlet pipe in conjunction with bolts to secure the movable baffle after adjustment, ensuring its stability.

[0008] 2. This utility model features a support frame at the air inlet of the air inlet pipe, connected to a dustproof net via a roller. When the combustion furnace is in use, the dustproof net is rotated and adjusted to the side of the air inlet of the air inlet pipe, without affecting the air intake. When the combustion furnace is not in operation, the dustproof net is rotated and adjusted to the surface of the air inlet of the air inlet pipe. At the same time, the metal block inside the dustproof net is magnetically connected to the magnet block on the surface of the air inlet of the air inlet pipe, preventing dust and impurities from entering the air inlet pipe and the combustion furnace through the exposed air inlet, thus affecting the safe operation of the combustion furnace.

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.

[0011] Example Please see Figures 1-4 The illustration shows a blowing device for a biomass combustion furnace, including a combustion furnace 1, an air inlet pipe 2 installed on the surface of the combustion furnace 1, an adjustment component and a protective component. The adjustment component is installed inside the air inlet pipe 2, and the protective component is installed at the air inlet of the air inlet pipe 2. When in use, the adjustment component adjusts the ventilation area inside the air inlet pipe 2 to control the air volume and air velocity entering the combustion furnace 1. Based on the aforementioned scheme, the adjustment assembly includes a limiting plate 3, bolts 4, and a movable baffle 5. The movable baffle 5 is inserted into the surface of the air inlet pipe 2. Limiting plates 3 are provided on both the upper and lower sides of the movable baffle 5 outside the air inlet pipe 2. Bolts 4 are threadedly connected to the surface of the limiting plate 3. The adjustment assembly also includes a scale strip 6, a pull ring 7, and a slide bar 8. The movable baffle 5 is provided with equidistant scale strips 6 on its surface. Pull rings 7 are fixedly connected to the outside of the movable baffle 5. Slide bars 8 are provided on both sides of the movable baffle 5. The slide bars 8 are slidably connected to the sliding groove opened on the inner wall of the air inlet pipe 2. A movable baffle 5 is installed inside the air inlet duct 2. By adjusting the position of the movable baffle 5 inside the air inlet duct 2, the ventilation area inside the air inlet duct 2 can be adjusted, thereby controlling the air volume and wind speed entering the combustion furnace 1. This facilitates the use of different biomass materials. Equidistant scale strips 6 are set on the surface of the movable baffle 5, which can quickly adjust the ventilation area inside the air inlet duct 2. In addition, a limiting plate 3 is set on the outside of the air inlet duct 2 in conjunction with bolts 4 to facilitate the fixing of the adjusted movable baffle 5 and ensure the stability of the movable baffle 5 after adjustment.

[0012] As a further embodiment of this invention, the protective assembly includes a roller 9, a dustproof net 10, and a support frame 11. The support frame 11 is fixedly connected to the air inlet of the air inlet pipe 2. The dustproof net 10 is movably connected inside the support frame 11 via the roller 9. The protective assembly also includes a metal block 12 and a magnet block 13. The metal block 12 is embedded inside the dustproof net 10. The metal block 12 is connected in conjunction with the magnet block 13 embedded at the air inlet of the air inlet pipe 2. The cross-sectional area of ​​the dustproof net 10 is larger than the cross-sectional area of ​​the air inlet of the air inlet pipe 2. A support frame 11 is installed at the air inlet of the air inlet pipe 2 and connected to a dustproof net 10 by a roller 9. When the combustion furnace 1 is in use, the dustproof net 10 is rotated and adjusted to the side of the air inlet of the air inlet pipe 2 so as not to affect the air intake of the air inlet pipe 2. In addition, when the combustion furnace 1 is not working, the dustproof net 10 is rotated and adjusted to the surface of the air inlet of the air inlet pipe 2. At the same time, the metal block 12 on the inside of the dustproof net 10 is magnetically connected to the magnet block 13 on the surface of the air inlet of the air inlet pipe 2 to prevent dust and impurities from entering the air inlet pipe 2 and the combustion furnace 1 through the exposed air inlet and affecting the safe use of the combustion furnace.

[0013] It should be noted that this utility model is a blower device for a biomass combustion furnace. First, the dustproof net 10 is rotated and adjusted to a position beside the air inlet of the air inlet pipe 2, so as not to affect the air intake of the air inlet pipe 2. Then, the biomass to be burned is placed inside the combustion furnace 1. When the biomass is burning, the motor is operated so that the blower, under the action of the motor output end, causes the air entering the air inlet through the air inlet pipe 2 into the combustion furnace 1, thereby increasing the flame during biomass combustion. According to the properties of different biomass, the position of the movable baffle 5 inside the air inlet pipe 2 is adjusted to adjust the ventilation area inside the air inlet pipe 2, so as to realize the air entering the combustion furnace 1. The volume and wind speed are controlled by setting equidistant scale strips 6 on the surface of the movable baffle 5, which can quickly adjust the ventilation area inside the air inlet pipe 2. In addition, a limiting plate 3 is set on the outside of the air inlet pipe 2 in conjunction with bolts 4 to facilitate the fixing of the movable baffle 5 after adjustment, ensuring the stability of the movable baffle 5 after adjustment. When the combustion furnace 1 is not working, the dust screen 10 is rotated and adjusted to the surface of the air inlet of the air inlet pipe 2. At the same time, the metal block 12 on the inner side of the dust screen 10 is magnetically connected to the magnetic block 13 on the surface of the air inlet of the air inlet pipe 2, preventing dust and impurities from entering the air inlet pipe 2 and the combustion furnace 1 through the exposed air inlet, which would affect the safe use of the combustion furnace.
