[0002] Oxygen supply blowers for sludge compound fertilizer production are mainly used in aerobic fermentation processes of sludge. By forcibly supplying oxygen, they promote the decomposition of organic matter by microorganisms, achieving sludge stabilization and harmless treatment. Their core function is to provide oxygen for the composting process. Simultaneously, they regulate the oxygen supply in real time through temperature and oxygen monitoring probes to ensure fermentation efficiency and safety. Oxygen supply blowers are primarily used to provide a stable oxygen supply for specific scenarios via compressed air or oxygen delivery equipment. However, existing oxygen supply blowers for sludge compound fertilizer production often produce gas containing particulate matter and other impurities, making filtration inconvenient and affecting usability.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] This embodiment is an oxygen supply fan for the production of sludge compound fertilizer with filtration function.

[0017] like Figure 1-3 As shown, the device includes a fan 1, an air inlet pipe 2 on the upper outer surface of the fan 1, an exhaust pipe 3 on one side of the outer surface of the fan 1, and a filter mechanism 4 on the upper outer surface of the air inlet pipe 2. The filter mechanism 4 includes an air guide hood 5, an annular hood 6, a filter screen 7, a mounting bracket 8, a scraper 9, a motor 10, a rotating shaft 11, a filter plate 12, a side plate 13, a sliding groove 14, an insert plate 15, a threaded groove 16, a threaded hole 17, and a threaded rod 18. The air guide hood 5 is fixedly installed on the upper outer surface of the air inlet pipe 2. The filter plate 12 is located at the upper end inside the air guide hood 5. Two sets of side plates 13 are located on the outer surfaces of the filter plate 12 on both sides respectively. Two sets of sliding grooves 14 are respectively opened at the upper ends of the inner surfaces of the air guide hood 5 on both sides.

[0018] A threaded hole 17 is opened at the upper end of the outer surface of one side of the slide groove 14. A threaded rod 18 is located in the middle of the threaded hole 17. An annular cover 6 is located at the upper end of the air guide cover 5. A filter screen 7 is located on the upper outer surface of the annular cover 6. A mounting bracket 8 is located at the lower end inside the annular cover 6. A motor 10 is located in the middle of the mounting bracket 8. A rotating shaft 11 is located on the upper outer surface of the motor 10. A scraper 9 is located at the upper end of the outer wall of the rotating shaft 11. Two sets of insert plates 15 are located on both sides of the lower outer surface of the annular cover 6. A threaded groove 16 is opened in the middle of the outer surface of one side of the insert plate 15. The side plate 13 and the slide groove 14 are slidably connected. The insert plate 15 and the slide groove 14 are also slidably connected. The threaded rod 18 is threadedly connected to the threaded hole 17 and the threaded groove 16.

[0019] It should be noted that this utility model is an oxygen supply fan for sludge compound fertilizer production with a filtration function. By starting the motor 10, the rotating shaft 11 is driven to rotate, which in turn drives the scraper 9 to rotate. The scraper 9 cleans the outside of the filter screen 7, reducing the accumulation of particulate impurities on the outside of the filter screen 7 and affecting gas flow. After being filtered again by the filter plate 12, the gas is discharged through the exhaust pipe 3 by the fan 1. This facilitates gas filtration and reduces the entry of particulate impurities into the fan 1, which affects its service life. By rotating the threaded rod 18, the threaded rod 18 can be removed. Then, the annular cover 6 can be pulled upwards, and the insert plate 15 can be slid along the slide groove 14. After removing the annular cover 6, the filter plate 12 can be pulled upwards, causing the side plate 13 to slide along the slide groove 14 and the filter plate 12 can be removed. This allows for easy installation, disassembly, and cleaning of the filter screen 7 and the filter plate 12.
