[0002] In the operation of kiln-head boilers, the air outlet device is a critical component, and its performance directly affects the boiler's operating efficiency and stability. Traditional kiln-head boiler air outlet devices have many problems in practical applications, seriously affecting the overall performance and user experience of the kiln-head boiler.

[0003] Traditional air outlet devices have relatively simple filtration structures, typically using fixed filter screens. Over long-term use, a large amount of dust, particulate matter, and other impurities gradually accumulate on the filter screen surface. These impurities not only clog the filter screen pores, increasing ventilation resistance, reducing air outlet efficiency, and increasing the energy consumption of the kiln head boiler; but also, because the filter screen is fixedly installed, cleaning requires disassembling the entire air outlet device or filter screen section, which is cumbersome, time-consuming, and labor-intensive. Frequent disassembly can also damage the device's sealing and structural stability, shortening its service life. Utility Model Content
