Problems solved by technology
[0002] At present, when the screw unloader is unloading, only open bellows are installed on both sides of the mine trough to extract wind and dust. Since they are all open, a large amount of air is required, and the dust removal effect is not good. Especially when unloading dry materials such as limestone, the pollution is serious and very serious. Affect the health of unloading workers

The invention relates to the field of dust extraction of unloaders, in particular to a mobile dust extraction method and device for a screw unloader. The mobile dust extraction method is characterized by including: arranging a mobile dust extraction unloader cover between the screw unloader and a mine groove, connecting a top cover of the dust extraction unloader cover with a lifting frame of the screw unloader through multiple layers of foldable sealing slide plates, keeping sealed between the screw unloader and the dust extraction unloader cover by the foldable sealing slide plates, covering two sides and top side of a carriage to be unloaded and an inlet of the mine groove to form a local sealed space when the carriage to be unloaded travels to the upper side of the mine groove, vacuumizing the sealed space during unloading, keeping the screw unloader moving back and forth from end to end along the carriage while keeping sealed by depending on retracting and stretching of the foldable sealing slide plates until unloading and dust extracting of the carriage are completed. Compared with the prior art, the mobile dust extraction method and device have the advantages that the device can move to a carriage unloading position, local air suction can be formed during unloading, dust extraction effect is improved, and manufacturing posts and working environment meet national standard requirements.
Description
technical field [0001] The invention relates to the field of dust removal for car unloaders, in particular to a mobile dust removal method and device for a screw car unloader. Background technique [0002] At present, when the screw unloader is unloading, only open bellows are installed on both sides of the mine trough to extract wind and dust. Since they are all open, a large amount of air is required, and the dust removal effect is not good. Especially when unloading dry materials such as limestone, the pollution is serious and very serious. Affect the health of unloading workers. Contents of the invention [0003] The purpose of the present invention is to provide a mobile dust removal method and device for a screw unloader, which overcomes the deficiencies in the prior art, and can follow the unloader to move to the position of each carriage, and form a local draft when unloading, improve the dust removal effect, and make production posts more efficient. The amount of...
