Zusammenfassung:	The utility model provides an automatic alarm device for a fluidized bed. The device comprises the fluidized bed, an air source, an air cylinder, a manual mechanical valve, a dual-pressure valve (1), a dual-pressure valve (2), a mechanical valve, a material tank, a plug and a whistle. The manual mechanical valve is connected with the first dual-pressure valve through a gas pipeline, and the first dual-pressure valve is connected with the air cylinder through a gas pipeline. The cylinder is connected with the mechanical valve through a gas pipeline; the air cylinder is connected with the dual-pressure valve (2) through a gas pipeline, and the mechanical valve is connected with the dual-pressure valve (2) through a gas pipeline; and the dual-pressure valve (2) is connected with the plug and the whistle through gas pipelines. According to the utility model, the problem of material leakage in the fluidized bed is solved, and the waste of materials is reduced, so that the utilization rate of the materials is impro
