Description

Technical Field

[0001] The invention belongs to the technical field of ammonium perchlorate production, and in particular relates to an automatic pouring device and method for barreled ammonium perchlorate. Background Art

[0002] Ammonium perchlorate is an inorganic compound, a white crystalline powder, and is deliquescent. Ammonium perchlorate is a strong oxidant, and will explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powder. Contact with strong acids may cause combustion and explosion. It is used to make explosives, fireworks, and as an analytical reagent. The raw material of ammonium perchlorate needs to be crushed before it can flow to the next process. Before crushing, the ammonium perchlorate is poured into the feeder, and after screening, it is sucked into the hopper of the crusher through a vacuum conveying device. Ammonium perchlorate is a hazardous chemical that is sensitive to heat, temperature, impact, friction, static electricity, and sparks. It is also corrosive. Ammonium perchlorate was originally stored in a tin barrel. After manually opening the barrel cover, untie the cotton rope of the plastic bag in the barrel, take out the plastic bag, pour the ammonium perchlorate into the feeder, and close the barrel cover. At present, the opening and closing of the lid and pouring of ammonium perchlorate in barrels are all handled manually. Relatively speaking, the manual work intensity is very high, and in the process of manual pouring, the monotonous and cumbersome movements occasionally lead to improper operation, causing the ammonium perchlorate to fall to the ground during the pouring process, resulting in a waste of raw materials. The whole process is cumbersome and monotonous, and manual labor is prone to visual fatigue and consumes a lot of energy. In addition, during the process of opening and closing the lid and pouring the material, the human body is always exposed to a dangerous environment, which poses certain safety hazards.
