Automatic deslagging device of lithium iron phosphate jet mill

The utility model relates to the technical field of lithium iron phosphate production equipment, in particular to an automatic deslagging device of a lithium iron phosphate jet mill. The device comprises a jet mill, an air milling cavity, a lithium iron phosphate feed port, a lithium iron phosphate discharge port, a crushed slag discharge assembly and a slag collection vehicle, in an actual production process, a part of particles which are extremely difficult to crush and foreign matter residues which are not intercepted by screening and discharging and the like always remain, and the existence of the residues is very unfavorable for the whole crushing process, so that only a jet mill needs to be stopped, and then the residues are manually cleaned; according to the utility model, when slag appears in the air mill cavity, the crushed slag discharging assembly is started, the upper and lower automatic butterfly valves automatically discharge the slag in a closed and open alternate opening and closing mode, and
