Description
Technical Field
[0001] The utility model relates to the technical field of drying equipment, in particular to a static pyrotechnic powder dehumidification and drying system. Background Art
[0002] At present, the pyrotechnic powder industry uses fixed gunpowder drying rooms to dry powder. Usually, a cart is placed in a fixed brick and tile house or a fireproof foam wall house, and a multi-layer tray is placed on the cart. The tray contains the pyrotechnic powder to be dried, and then the materials in the drying room are dried through low-temperature heat circulation of air energy. The current fixed gunpowder drying room, but this method has limited drying efficiency and is prone to various problems:
[0003] 1) During the drying process in the drying room, the hot air directly touches the powder in the cart. As the hot air flows, the drug dust is deposited in the drying room and the air duct, which easily creates a safety hazard. When static electricity is generated in the drying room and encounters friction from the movement of objects, it will cause an explosion hazard;
[0004] 2) The low-temperature heat cycle of air energy will form air circulation in the drying room, which will cause part of the pyrotechnic powder dust to enter the hot air circulation channel, which is very likely to cause safety accidents;
[0005] 3) The drying room only relies on heat circulation, which can easily cause uneven drying and zoning of drying degrees in the upper and lower parts and the front and back of the drying room. Some drying rooms add floor heating on the ground or install heat sinks on the walls, but this only enhances the drying effect in certain directions and still cannot solve the problem of overall drying uniformity in the drying room.
