Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0022] see figure 1 , a kind of preparation technology of novel expanded ammonium nitrate explosive, its processing step is:

[0023] The first step is to dissolve in the water phase: add a certain amount of water to the water phase dissolution tank, and the ammonium nitrate and sodium nitrate that have been measured and crushed are transported to the water phase tank for dissolution by the screw conveyor, and the addition of ammonium nitrate, sodium nitrate and water The mass percent addition ratio based on the total amount of the water phase is: ammonium nitrate 92: sodium nitrate 0-3: water 8, the mass percent concentration of nitrate in the solution is controlled at 90-93%, and the temperature after dissolution is controlled at 110 ~ 120 ℃, and set up multiple water phase dissolution tanks for alternate use. Multiple water phase dissolving tanks can be used ...

Abstract

The invention relates to a process for preparing novel expanded ammonium nitrate explosive, which comprises the following steps: water-phase dissolving and oil-phase melting; mixing two phases; expanding crystallization; realizing uninterrupted discharging through alternately converting vacuum cavities; mixing expanded explosive with a functional additive which is subjected to measurement after a product is dropped into a cool mixed spiral through a feeding bin; dropping a prepared semifinished product of the expanded explosive into a suspension conveyer through a spiral conveying device; and conveying the semifinished product to a filling package workshop by the suspension conveyer for explosive filling to obtain a finished product of the expanded ammonium nitrate explosive through package. The invention is the process for preparing the expanded ammonium nitrate explosive with safety and environmental protection, zero discharge of pollutant, small online explosive amount, high operating safety and high automatic control.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of civil explosives, and relates to a preparation process of a novel expanded ammonium nitrate explosive with the characteristics of less processing and manufacturing links, short process route, few process facilities, compact equipment layout, safety and environmental protection. 【Background technique】 [0002] At present, the existing expanded ammonium nitrate explosive preparation process includes continuous expansion and continuous drug mixing. The continuous expansion part of the process is carried out in the ammonium nitrate continuous expansion device. Condenser, continuous crystallizer, storage tank, and discharge screw. The continuous expansion part process includes water phase material crushing, dissolution, vacuum crystallization and material transportation. The continuous mixing part process is in the continuous mixing device of expanded ammonium nitrate explosive The expanded am...
