Description

Technical Field

[0001] The present application relates to the technical field of boilers, and more specifically, to a boiler with an automatic descaling function. Background Art

[0002] A boiler is a device that inputs fuel and, after energy conversion, outputs steam, high-temperature water or an organic heat carrier with a certain amount of thermal energy. Most boilers in our daily lives convert the cold water inside into hot water through energy conversion. Scale is the minerals in hard water that adhere to the inside of the container after boiling, in the form of white lumps or powder. The thermal conductivity of scale is low. If the scale formed in the boiler is too thick, the boiler efficiency will be reduced.

[0003] The document with the prior art publication number CN115435497A provides a boiler with an automatic descaling function, including a base, a furnace body, a top cover, a water inlet pipe and a pressure relief pipe. A sealing plate is fixedly installed on the top of the base, an exhaust pipe is fixedly installed on the right end of the sealing plate, and a bearing is fixedly installed in the middle of the sealing plate. Through the cooperation of the sealing plate, rotating shaft and fan blades and other structures, when the boiler is boiling water, the fan blades are blown by the generated hot steam and the rotating shaft is driven to rotate. When the rotating shaft rotates, the first descaling component and the second descaling component are driven to rotate. The first descaling component contacts the inner wall of the furnace body, and the second descaling component contacts the top of the base. When the water boils and scale is attached to the inner wall of the furnace body and the top of the base, the scale is scratched to prevent the attachment of the scale. The impact of the water vapor is used as the power, which saves energy and automatically cleans the scale without manual cleaning.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] 1. The driving force of the fan blades driven by steam is low, and when the scale is relatively solid, it is difficult to drive the scraper to scrape off the scale;

[0006] 2. The scraping direction is only along the inner wall of the boiler in the circumferential direction, the path is single, and the scraping effect is poor.

[0007] Regarding the above-mentioned related technologies, the inventor believes that the driving force used to drive the fan blades to rotate by steam is low. When the scale is relatively solidified, it is difficult to drive the scraper to scrape off the scale. The scraping direction is only along the circumferential direction of the boiler's inner wall. The path is single and the scraping effect is poor.

[0008] In view of this, we propose a boiler with automatic descaling function. Utility Model Content

[0017] Through the above scheme, when the rotating frame rotates, the gear rolls along the gear ring, thereby driving the rotating shaft to rotate.
