Description

Technical Field

[0001] The present application relates to the technical field of chemical production feeding equipment, and in particular to a semi-automatic bagged ammonium nitrate feeding device. Background Art

[0002] The production of mixed porous granular ammonium nitrate oil explosives utilizes ammonium nitrate, an ammonium salt that appears as colorless, odorless, transparent or white crystals. It is highly soluble in water, easily absorbs moisture and agglomerates, absorbs large amounts of heat when dissolved, and decomposes explosively upon impact or heat, as well as upon contact with alkali. It is an oxidizing agent and is used as a fertilizer and chemical raw material. Ammonium nitrate packaging bags are typically made from polyester fibers such as polypropylene and polyethylene and are cube-shaped with a rectangular base.

[0003] In chemical production, the feeding process of hazardous chemicals such as ammonium nitrate usually relies on manual operation. The ammonium nitrate is first manually transported to the feeding table, and then the on-site operator manually cuts the packaging bag to feed the material. This not only increases the labor intensity of the operator, but also poses a major safety hazard. Therefore, improvements are now being made to the semi-automatic bagged ammonium nitrate feeding device. Utility Model Content
