Continuous drying device for powdery simple substance explosive

Abstract

The invention discloses a continuous drying device for powdery simple substance explosive. A drying station is placed on the upper end face of a hot water circulating jacket and supported by an inner support frame body, a static rotation connecting unit can drive the drying station under the action of a driving transmission unit to rotate at a proper rotational speed, and thermostatic hot water in a hot water storage tank can be circularly supplied to the hot water circulating jacket; and a distribution plate, a scraping plate and a rake feeder are arranged along the radial direction of the drying station through an outer support frame body. The powdery simple substance explosive is conveyed to the drying station between the distribution plate and the scraping plate by a feeder; the powdery explosive is subjected to processes of spreading, water evaporation, raking and water evaporation in turn along with the circular motion of the drying station; and when the drying station rotates for one circle, the dried powdery simple substance explosive is scraped into a hopper by the scraping plate. The device solves the problems of continuous operation and field isolation in the powdery simple substance explosive drying process, and has the predominant advantages of good inherent safety, short drying process period, low energy consumption, high efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of propellants and explosives, and mainly relates to a drying device for powdery single-substance explosives, in particular to a device capable of realizing continuous drying of powdery single-substance explosives in a relatively short period of time. Background technique [0002] The traditional drying process of elemental explosives is a manual oven drying method. In this method, the filtered powdery elemental explosives with a water content of 10% to 15% are loaded into aluminum trays, each tray is loaded with 5kg to 10kg, and multiple Place the aluminum plate in a vacuum drying oven, dry it for 4 hours at a vacuum degree of -0.07MPa and a temperature of 80°C to 90°C, turn off the vacuum switch, and manually turn the drug powder once; then, continue to dry for another 4h under the same conditions, and dry After completion, it will be moved out manually. The entire drying process is carried out under stat...
