Description

Technical Field

[0001] This utility model relates to the field of biomass boilers, and in particular to a slag recovery device for biomass boilers. Background Technology

[0002] A biomass boiler is a heating device that uses biomass energy (such as straw, sawdust, rice husks, biogas, and other renewable organic materials) as fuel. Its working principle is to generate heat energy by burning biomass fuel to heat water or steam for industrial processing, heating, or power generation. Compared to traditional coal-fired boilers, biomass boilers have advantages such as low carbon emissions (CO2 emissions after combustion can be absorbed by plants, resulting in near-zero net emissions), renewable energy (utilizing agricultural / forestry waste), and economic efficiency (low fuel costs). They are widely used in factories, farms, and district heating systems and are one of the important technologies for the green energy transition.

[0003] While existing technologies can achieve a certain degree of slag cleaning effect in biomass boilers, they also have drawbacks: the slag cleaning of existing biomass boilers is inconvenient, resulting in long cleaning cycles and affecting the overall work progress. In view of this, we propose a slag recycling device for biomass boilers, which solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a slag recovery device for biomass boilers.

[0005] The technical solution of this utility model is as follows: A slag recycling device for a biomass boiler includes a base, a rotating column, a collection trough, a body and a scraper. The body is fixed at the upper end of the base, and a collection trough is inserted into the inside of the base. A mounting frame is fixed on one side of the upper end of the collection trough, and a rotating column is provided on one side of the mounting frame. The outer wall of the rotating column is provided with scrapers with elastic elements arranged in a ring array, and a scraper with elastic elements is provided on one side of the rotating column.

[0006] When using this device, the rotating cover can be opened, and then the collection trough can be inserted into the groove at the bottom of the base. The rotating column can be inserted into the body until it reaches the bottom. After reaching the bottom, the base and body can be lifted a short distance using a jack. Then, the motor can be started, and the handle can be manually and slowly pulled outward. As the scraper moves outward, it scrapes off the dirt on the inner wall of the body. The scraped residue will be carried out of the body by the lower half of the scraper and fall into the collection trough. This device can achieve convenient and efficient removal of biomass boiler slag and has high practicality.

[0007] Preferably, a handle is fixed to one side of the outer wall of the collection tank, and a groove is provided at the lower end of the base. The groove can simplify the loading and unloading process, avoid the risk of leakage caused by the displacement of the collection tank, and improve operational safety.

[0008] Preferably, the groove is designed with an open side facing the collection slot, and a roller is fixed at the lower end of the collection slot. The roller is inserted into the groove, and the groove opening cooperates with the roller to achieve smooth insertion and removal of the collection slot, reduce frictional resistance, reduce labor consumption, and extend the service life of the component.

[0009] Preferably, a fixing frame is fixed on one side of the mounting frame, and a rotating shaft is rotatably installed inside the fixing frame. One side of the rotating shaft is fixedly connected to one end of the rotating column to prevent the rotating column from swaying, ensure the stability of the scraper operation, and avoid damage to the inner wall.

[0010] Preferably, a motor is fixed to one side of the outer wall of the mounting bracket, and the output shaft of the motor is fixedly connected to one end of the rotating shaft. The motor drives the rotating shaft to achieve automatic rotation, replacing manual operation, improving scraping efficiency and reducing labor intensity.

[0011] Preferably, a telescopic rod is inserted into the outside of the rotating column, and a second spring is provided at the bottom of the telescopic rod and the inside of the mounting column. The scraper is fixedly connected to one end of the telescopic rod. The telescopic rod and the second spring enable the scraper to have adaptive telescopic capability, adapt to the unevenness of the inner wall, enhance the thoroughness of dirt removal, avoid missed scraping, and protect the inner wall of the boiler.

[0012] Preferably, a rod is provided on one side of the scraper, and a limiting key is provided on the outer wall of the rod. The rod is inserted into the interior of one end of the rotating column. A spring is provided between the scraper and the rotating column. The rod and the limiting key ensure that the scraper elastically presses against the inner wall, and the spring provides buffer pressure, effectively scraping away stubborn residue and preventing scraper wear, thereby improving the residue collection rate.

[0013] Preferably, a rotating cover is provided on one side of the main body, and multiple pipes are provided on the outer wall of the main body. The rotating cover facilitates maintenance and component replacement, and the pipe design meets the multi-functional needs of the boiler, taking into account both maintenance convenience and equipment expandability, reducing the overall operation and maintenance cost. The main body is a commonly used biomass boiler.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model can utilize a combination of manual and electric drive, along with scrapers and scraper discs, to clean and scrape away ash from inside the boiler, achieving a highly efficient and convenient cleaning effect. After cleaning, the ash can fall directly into the collection tank for collection and processing.

[0016] Second, based on the first beneficial effect, this device integrates motor drive and elastic scraper to achieve rapid and thorough cleaning. The roller guide and handle pull-out design simplify the operation process. The adaptive extension and buffer mechanism protects the equipment and extends its service life. With these three advantages, it is suitable for the regular maintenance of various biomass boilers and has broad market prospects.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
