[0025] Embodiment

[0026] As Figures 1 to 5As shown in the figure, a steam boiler heating device for a public area is provided. Inside the housing 1, there is a heating mechanism 7 and a cleaning mechanism. The heating mechanism 7 includes: a combustion chamber 10 and a furnace drum 9; the cleaning mechanism includes: a furnace drum cleaning component and a housing cleaning component. The combustion chamber 10 is arranged and fixed inside the housing 1, connected to the gas port 6 on the housing 1 through a pipeline, and externally connected to a gas pipeline through the gas port 6; the first smoke box 2 and the second smoke box 5 are respectively arranged at both ends of the housing 1. The top of the first smoke box 2 is fixedly connected to the exhaust port 3. The combustion chamber 10 and the second smoke box 5 are connected through the first smoke pipe 11 and the second smoke pipe 12. The first smoke box 2 and the second smoke box 5 are connected through the second smoke pipe 12. The smoke boxes are used to increase the flow length of the high-temperature flue gas on the heating surface, thereby improving the heat exchange efficiency; the top of the housing 1 is fixedly connected to the steam port 4, and the front end is provided with a gas port 6; the furnace drum 9 serves as the direct heating surface and space for the flame in the combustion chamber 10. The furnace drum 9 directly transfers the heat generated by fuel combustion to water, causing the water to be heated and ultimately converted into steam. The furnace drum 9 is made of high-temperature resistant materials to withstand the high temperature generated during the combustion process and is arranged inside the housing 1. The combustion chamber 10 is used to place fuel and burn the fuel through a configured ignition device. The gas port 6 is a pipeline interface leading to the combustion chamber and is used to transport gas to the combustion chamber 10. The furnace drum 9 is connected to the combustion chamber 10, and the other end is connected to the inner wall of the housing 1; as Figure 2 As shown in the figure, the furnace drum cleaning component includes: a driven gear 16 and a scraper 17. A circular hole is opened at the central position of the driven gear 16. The inner side of the circular hole is rotatably connected to the front end of the furnace drum 9, and the driven gear 16 is externally connected to a driving member for rotation; one end of the scraper 17 is connected to a position offset from the center of the circle on the side of the driven gear 16. The side of the scraper 17 close to the furnace drum 9 is in sliding contact with the furnace drum 9. By rotating the driven gear 16, the scraper 17 is enabled to rotate along the outer peripheral side of the furnace drum 9 and clean the outer side of the furnace drum 9 during rotation, thereby preventing scale accumulation; as Figure 3 As shown in the figure, the housing cleaning component includes: a toothed ring 14, a plurality of connecting rods 15 and a circular ring. The toothed ring 14 is rotatably sleeved on one end inside the housing 1 and is driven to rotate by a driving member; the circular ring is rotatably sleeved on the other end inside the housing 1; a plurality of connecting rods 15 are connected between the circular ring and the toothed ring 14. A raised scraping blade is provided on the side of the connecting rod 15 close to the inner wall of the housing 1.

[0027] There is room for improvement in the heat exchange efficiency of the existing heating device. During the process of the boiler heating water into steam, heat transfer is not always efficient, and some heat may be lost, resulting in energy waste and affecting the overall heating effect. In this embodiment, as Figure 5 As shown in the figure, a plurality of fins 18 are provided on the furnace drum 9. Each fin 18 is provided with a through circular hole, and the diameter of the circular hole matches the diameter of the furnace drum 9. The fins 18 can increase the contact area between the furnace drum 9 and water, thereby improving the heat exchange efficiency.

[0028] As Figure 4As shown, a plurality of channels are provided on one side of the scraping plate 17 close to the furnace lining 9. The positions of the plurality of channels respectively correspond to the positions of the plurality of fins 18, and the thickness of the channels matches the thickness of the fins 18, so that the fins 18 can pass through the inside of the channels. By the cooperation of the slots of the scraping plate 17 and the fins 18, when the scraping plate 17 rotates, the scale on the surface of the fins 18 can be cleaned through the channels.

[0029] Preferably, the plurality of fins 18 are arranged at equal intervals to improve the uniformity of heat exchange.

[0030] As Figure 2 shown, the driving member includes: a motor 8 and a driving gear 13. The bottom of the motor 8 is fixedly connected to the housing 1; the driving gear 13 is sleeved on the output shaft of the motor 8. The top of the driving gear 13 meshes with the driven gear 16, and the bottom meshes with the toothed ring 14.

[0031] In some embodiments, the scraping blade is inclined. For example, the inclination direction of the scraping blade is opposite to the rotation direction of the housing cleaning component, which has a better cleaning effect on the inner side wall of the housing 1.

[0032] In this embodiment, a through hole is provided at the front of the driven gear 16, and the diameter matches the diameter of the front part of the furnace lining 9. The driven gear 16 is connected to the furnace lining 9 through the round hole and can only rotate in place under the action of the furnace lining 9 and the scraping plate 17.

[0033] In this embodiment, the outer diameter of the toothed ring 14 matches the inner diameter of the housing 1. The toothed ring 14 is restricted by the inner wall of the housing 1 and can only rotate in place.

[0034] During use, by starting the motor 8, the motor 8 drives the driving gear 13 to rotate synchronously while rotating. While the driving gear 13 rotates, it drives the toothed ring 14 to rotate. The toothed ring 14 drives the plurality of connecting rods 15 thereon to rotate. The scraping blades provided on the connecting rods rub against the inner wall of the housing 1, so as to clean the scale attached to the inner wall of the housing 1 and keep the inner wall of the housing 1 clean;

[0035] While the driving gear 13 rotates, it will drive the driven gear 16 to rotate together. After the driven gear 16 rotates, it drives the scraping plate 17 connected thereto to rotate. While the scraping plate 17 rotates, it rubs against the outer sides of the furnace lining 9 and the fins 18, so as to clean the scale attached to the furnace lining 9 and the fins 18 and avoid affecting the effect of heating water;

[0036] While the fuel gas burns inside the furnace liner 9, heat is transferred to the furnace liner 9. The furnace liner 9 transfers the heat to the water inside the outer shell 1, heating the water and causing it to boil and generate steam. While the furnace liner 9 is being heated, a part of the heat is transferred to the fins 18, raising the temperature of the fins 18. The fins 18 will heat the water around them. The fins 18 increase the contact area between the furnace liner 9 and the water, improving the efficiency of heat exchange.

[0037] The above-disclosed are only several preferred specific embodiments of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
