Problems solved by technology

[0004] However, the water phase and oil phase produced in the current production method of expanded ammonium nitrate explosive are very easy to mix unevenly during mixing, resulting in unstable product quality after expansion
At the same time, in the process of mixing and puffing, it is easy to have incomplete puffing, which makes the detonation velocity and violent force of the explosive not up to the standard, and affects the quality of the finished explosive.

Embodiment 1

[0037] Such as figure 1 As shown, the present embodiment provides a kind of production method of expanded ammonium nitrate explosive, comprises the following processing steps:

[0038] S1. Preparation of water phase: After the ammonium nitrate is transported by the tanker, the ammonium nitrate is crushed by the crusher. After the crushed ammonium nitrate is measured, it is added to the dissolving tank, and steam is introduced into the dissolving tank, so that the ammonium nitrate is heated and dissolved in the steam In the condensed water, a liquid ammonium nitrate solution is obtained, and the liquid ammonium nitrate solution is transported to the water phase storage tank through the pump body. 0.25% of the total mass of the liquid ammonium nitrate solution in the phase storage tank is used to measure the expansion agent, and then add it to the water phase storage tank, so that the expansion agent is dissolved in the ammonium nitrate solution to obtain an aqueous phase liquid...

Embodiment 2

[0045] Such as figure 1 As shown, the present embodiment provides a kind of production method of expanded ammonium nitrate explosive, comprises the following processing steps:

[0046] S1. Preparation of water phase: After the ammonium nitrate is transported by the tanker, the ammonium nitrate is crushed by the crusher. After the crushed ammonium nitrate is measured, it is added to the dissolving tank, and steam is introduced into the dissolving tank, so that the ammonium nitrate is heated and dissolved in the steam In the condensed water, a liquid ammonium nitrate solution is obtained, and the liquid ammonium nitrate solution is transported to the water phase storage tank through the pump body. 0.27% of the total mass of the liquid ammonium nitrate solution in the phase storage tank is used to measure the expansion agent, and then add it to the water phase storage tank, so that the expansion agent is dissolved in the ammonium nitrate solution to obtain an aqueous phase liquid...

Embodiment 3

[0053] Such as figure 1 As shown, the present embodiment provides a kind of production method of expanded ammonium nitrate explosive, comprises the following processing steps:

[0054] S1. Preparation of water phase: After the ammonium nitrate is transported by the tanker, the ammonium nitrate is crushed by the crusher. After the crushed ammonium nitrate is measured, it is added to the dissolving tank, and steam is introduced into the dissolving tank, so that the ammonium nitrate is heated and dissolved in the steam In the condensed water, a liquid ammonium nitrate solution is obtained, and the liquid ammonium nitrate solution is transported to the water phase storage tank through the pump body. 0.3% of the total mass of the liquid ammonium nitrate solution in the phase storage tank is used to measure the expansion agent, and then add it to the water phase storage tank, so that the expansion agent is dissolved in the ammonium nitrate solution to obtain an aqueous phase liquid....

Abstract

The invention relates to a production method of expanded ammonium nitrate explosive, which belongs to the technical field of explosive production. The production method of the expanded ammonium nitrate explosive comprises the following steps: after the ammonium nitrate is crushed, steam is introduced to dissolve it to obtain a liquid ammonium nitrate solution; In the water phase storage tank; after the compound oil is melted, it is transported to the oil phase storage tank for heat preservation and storage; the water phase is mixed with the oil phase to obtain a premixed liquid; Feed into the storage tank; add the sensitizer into the storage tank, mix and transport it by screw, and transport it to the silo through hanging cold medicine to get the semi-finished product; pack it separately to get the finished product of expanded ammonium nitrate explosive. The effect of the invention is that it can effectively improve the mixing uniformity of the oil phase and the water phase, and at the same time improve the puffing uniformity in the puffing process, so that the quality of the prepared finished puffed ammonium nitrate explosive is stable.

Description

technical field [0001] The invention belongs to the technical field of explosive production, in particular to a production method of expanded ammonium nitrate explosive. Background technique [0002] Ammonium nitrate explosive is a powdery explosive mechanical mixture, which is one of the most widely used industrial explosive varieties, with medium power and certain sensitivity. [0003] At present, the existing preparation process of expanded ammonium nitrate explosive includes the preparation of ammonium nitrate water phase and the preparation of expansion agent oil phase, and then the prepared water phase and oil phase are mixed and expanded to prepare the finished ammonium nitrate explosive. [0004] However, the water phase and the oil phase produced in the current production method of expanded ammonium nitrate explosive are very easy to mix unevenly during mixing, resulting in unstable product quality after expansion. Simultaneously, in the process of mixing and puffi...
