Description

Technical Field

[0001] The utility model relates to the technical field of ammonium nitrate oil explosives, in particular to equipment for preparing emulsified granular ammonium nitrate oil explosives. Background Art

[0002] Ammonium nitrate oil explosive is a common explosive. Because of its low cost, simple preparation and relatively insensitive, it is often suitable for use in open-air large-scale blasting occasions with large apertures and large charges. When producing modified ammonium nitrate oil explosive, it is often necessary to prepare the water phase by configuring equipment so as to compound with the oil phase solution later to improve production efficiency. Ammonium nitrate needs to be continuously heated when mixed with water. Since the mixing temperature needs to be regulated during operation (the specific temperature range is up to 72°C), electric heating pipe fittings are required to heat the solution in time. At present, when the existing water phase solution configuration equipment is in use, the electric heating pipe fittings are generally installed on the side wall of the warehouse body, resulting in the temperature near the side wall in the warehouse body being greater than the temperature in the center of the warehouse body, and the heating effect is not ideal, which affects the mixing effect of the water phase solution. At the same time, when the electric heating pipe fittings are damaged, the overall heating pipe needs to be replaced, which increases the cost of repair or maintenance.

[0003] For example, the utility model patent with publication number CN217549596U discloses a device for preparing an aqueous phase solution for the production of modified ammonium nitrate explosives, the structure of which includes a bin body, a stirring assembly, an electric heating pipe, a push cylinder, a protective member, a shell, a sliding door, an insulating layer, and a support. When the device is in use, the electric heating pipe fittings are generally installed on the side walls of the bin body, resulting in the temperature near the side walls in the bin body being greater than the temperature in the center of the bin body, resulting in an unsatisfactory heating effect, which affects the mixing effect of the aqueous phase solution. At the same time, when the electric heating pipe fittings are damaged, the overall heating pipe needs to be replaced, which increases the cost of repair or maintenance. Utility Model Content
