Description

Technical Field

[0001] The utility model belongs to the technical field of emulsion explosives, and in particular relates to a water-oil phase feeding device for the production of emulsion explosives. Background Art

[0002] Emulsion explosives are new water-containing explosives developed in the 1960s and 1970s. They have excellent explosion, safety and water resistance and are widely used in engineering blasting. Emulsion explosives are usually composed of oxidants, reductants and other additives. They are a paste-like plastic body made by emulsification. When preparing this emulsion explosive, firstly, the oxygen-containing acid salt and the above-mentioned organic monomer that can undergo polymerization are dissolved in water to form an aqueous solution, and at the same time, hydrocarbon fuel and emulsifier are mixed to form an oily mixture, and then the above two substances are mixed and stirred to form an oil-in-water type emulsion explosive.

[0003] In the production process of emulsion explosives, the water phase must be prepared first. Water, ammonium nitrate, sodium nitrate and other raw materials need to be added to the water phase raw material tank, stirred and dissolved in the tank to form the water phase, and then emulsifiers, composite wax and other raw materials are added to the oil phase raw material tank, stirred in the tank to form the oil phase; the water phase and the oil phase are then extracted from their respective feed tanks, mixed and transported to the emulsifier for further processing. The water phase raw materials in the existing water phase raw material tanks are often not completely dissolved in water due to their large particle size, resulting in uneven mixing of the water phase raw materials and the oil phase raw materials, which in turn affects the reaction rate of the water and oil phases; and in the existing water-oil phase mixed feed tank, when the oil phase and the water phase are mixed in the existing mixed feed tank, some materials are prone to adhere to the inner wall of the mixed feed tank, which not only affects the accuracy of the water-oil phase batching, but also causes a waste of raw materials, thereby affecting the production quality of emulsion explosives.
