The invention discloses a cleaning device for an air inlet of a moisture removing fan. The cleaning device comprises an air inlet nozzle (1), a cleaning wheel (6) and a bearing I (4). The air inlet nozzle (1) is fixed at the air inlet of the moisture removing fan. The bearing I (4) is sleeved at the upper end of the air inlet nozzle (1). The lower end of the air inlet nozzle (1) is provided with an end cover (3) and a seal strip (2). The cleaning wheel (6) comprises blades (7), a loop (8) and cleaning pipes (9). One end of each blade (7) is movably connected to a bearing II (11), and the other end of each blade (7) is fixed on the inner surface of the loop (8). The cleaning pipes (9) are evenly distributed on the outer surface of the loop (8). A slot (10) is reserved in the bottom of each cleaning pipe (9). The loop (8) is in close fit with the bearing I (4). The cleaning device has the advantages that cut tobacco on a screen can be cleaned automatically, continuous and effective operation of the moisture removing fan is guaranteed, frequency of manual screen maintenance is reduced, and production cost is lowered.
Description
technical field [0001] The invention relates to a cleaning device, in particular to a cleaning device for the air inlet of a moisture exhaust fan, and belongs to the technical field of tobacco machinery. Background technique [0002] At present, in the production process, after the expanded shredded tobacco is expanded by the expansion tower, it needs to be dampened by the dampening drum again. The re-moisture drum uses the method of air-compressed air atomization to soften the water to re-moisten the shredded tobacco. During the atomization, water mist will be formed in the re-moisture drum, and the shredded tobacco will absorb part of it. Due to the crushing of tobacco leaves in the drum, the shredded tobacco components will be gelled in the water mist. In order to prevent the pipeline of the exhaust fan from being blocked, a filter screen should be installed at the inlet of the exhaust fan. The conventional filter screen has no self-cleaning function, and the filter scr...
