Description

Technical Field

[0001] The utility model relates to the field of ammonium nitrate explosive processing, and more specifically, to an automatic device for continuously mixing high-fluidity expanded ammonium nitrate explosive. Background Art

[0002] Ammonium nitrate explosive is a powdered explosive mechanical mixture, one of the most widely used industrial explosives, with medium power and certain sensitivity. It is hygroscopic and agglomerated, and its sensitivity and power are significantly reduced after being damp, while it produces poisonous gas. Under the action of weak external excitation energy (such as mechanical, thermal, electrical, and optical), the detonator can burn and quickly turn into a sensitive explosive that detonates. During the production of ammonium nitrate explosive, production personnel need to mix the ammonium nitrate explosive, so an automatic device for continuous mixing of highly fluid expanded ammonium nitrate explosive is needed;

The advantages of this utility model are: ammonium nitrate and wood powder are continuously fed to the premixer according to the set flow rate, thereby ensuring the continuity and stability of the mixed medicine; the feeding system uses a precise metering device, which not only ensures the accuracy of the ratio, but also reduces manual operation, greatly reducing the unsafe factors in the production process; the mixing is uniform, the cooling medicine is sufficient, and the product quality and performance are guaranteed.
