Description

Technical Field

[0001] The utility model relates to the technical field of boiler cleaning, and more specifically to a device for cleaning dust accumulation in a steam boiler. Background Art

[0002] As a key equipment for energy conversion, boilers can generate hot water or steam to provide the required heat energy for industrial production and life. At the same time, they can also convert thermal energy into mechanical energy through steam power devices, or convert mechanical energy into electrical energy through generators. However, during operation, the flue gas generated by the boiler contains harmful gases and tiny particles, which will cause pollution if directly discharged into the air. Therefore, purification devices are usually used to treat these flue gases.

[0003] However, the problem that still occurs during the purification process is that the collected flue gas usually contains a mixture of dust and oil, which are easy to remain and adhere to the inner wall of the pipe connecting the boiler and the purification device. When the smoke in the flue pipe reaches a certain amount, it will cause the flue gas circulation efficiency of the flue pipe to decrease, thereby affecting the purification device's treatment rate of the flue gas and reducing the practicality of the purification device.

[0027] The dust cleaning component 4 is arranged inside the flue pipe 2. The dust cleaning component 4 includes a limiting shell 40, a motor 41, a threaded rod 42, a movable block 43, and a scraper ring 44. The outer surface of the limiting shell 40 is fixedly installed on the inner surface of the flue pipe 2, the surface of the motor 41 is fixedly installed on the outer wall of the end of the limiting shell 40, the threaded rod 42 is arranged inside the limiting shell 40, and the side end is fixedly connected to the output end of the motor 41, the inner surface of the movable block 43 is threadedly connected to the outer surface of the threaded rod 42, and the outer surface is slidably installed on the inner surface of the limiting shell 40, and the outer surface of the middle part of the scraper ring 44 is fixedly installed on the side of the movable block 43.

[0028] It also includes a dust collecting component 5, the top of the dust collecting component 5 and the inner surface of the flue pipe 2 are detachably mounted.

[0029] The dust cleaning assembly 4 further includes a filter plate 45 and an auxiliary dust cleaning mechanism 46.

The outer surface of the auxiliary dust cleaning mechanism 46 is movably mounted on the inner surface of the scraper ring 44 and is arranged below the filter plate 45.

[0030] By setting a filter plate 45, which is a fan-shaped filter plate and is fixedly installed on the inner wall of the upper half of the scraper ring 44, the scraper ring 44 can prevent the dust and impurities near the top from falling from the inside of the scraper ring 44 to the opposite position of the moving direction of the scraper ring 44 during the process of scraping along the inner wall of the flue pipe 2, thereby improving the cleaning effect of the inner wall of the flue pipe 2.

After completing the collection of the accumulated dust and impurities, the staff can move the movable plate 52 slidably installed on the surface of the flue pipe 2, so that the movable plate 52 slides along the surface of the limit block 51 and separates from each other. After that, the dust collecting box 50 fixed to the flue pipe 2 by the movable plate 52 can be taken out, and the collected accumulated dust and impurities can be processed.
