[0002] When the units in the heat source plant are in operation, they need to use a blower to provide air for the combustion of coal powder and other fuels in the furnace through the air supply duct. In order to prevent foreign objects from entering the duct during air transportation and damaging the fan blades of the blower, and to prevent a large amount of dust from entering the furnace during long-term operation and affecting the combustion effect in the furnace, a filter needs to be installed at the entrance of the air supply duct.

[0003] The utility model with the existing authorization announcement number CN219168001U discloses a filter replacement and cleaning device for the air supply duct of a heat source plant, including a frame and multiple lifting mechanisms. A pair of limit bars are arranged on the upper and lower inner walls of the frame. A filter is arranged in the frame and on the side of the limit bar close to the air supply duct. The filter is horizontally slidably connected to the frame.

[0004] By adopting the above technical solution, when the filter is replaced and cleaned, the filter is always in contact with the air inlet of the air supply duct, which can prevent foreign matter from entering the air supply duct during the cleaning process of the filter. The scraper is driven by the lifting mechanism to clean the surface of the filter, which saves the cleaning time of personnel and improves the overall work efficiency. However, when the filter is cleaned, the cleaned dust still floats in the surrounding air with the above technical solution, causing it to adhere to the surface of the filter again, and it does not have the ability to be easily replaced. After long-term use, when the filter is aged and needs to be replaced, it is very cumbersome, which not only reduces the cleanliness of the filter when cleaning, but also reduces the applicability of the device.
