TH584B - Mass production of oil-water-based explosives - Google Patents

Abstract

Methods and equipment are determined for the efficient and safe production of periodic volumes of non-insensitive oil-water-mixed explosives. Such methods do not use superfluous mixing or emulsification techniques. The method consists of pouring the oil of the mixture into a rotating mixer with internal blades and gradually adding the explosive liquid. The oil type is mixed with explosive water by supporting a large diameter charge.

Claims (8)

1.Method of production of oil-blended explosives components With water-in-oil with a high ratio Which is not sensitive to Stimulated with an explosive strainer consists of a procedure of (a) inserting a specified amount of oil / skin puller into a cylinder with an internal blade. Drum-like mixer can rotate It has an internal diameter of at least 1.5 m and preferably 1.5 to 2.5 m. (B) Rotating the drum-like mixer around its longitudinal axis at between 8-16 rpm while filling the volume. Of the liquid.The filling of such liquid is done continuously under For a period of not less than 10 minutes or allow free fall of the material Inside the mixer at a drop velocity of 5 to 7 m / s to produce the blended explosives with a distribution of droplet sizes from 1-10 μm (um). 2. The method as requested by claim 1 consists of steps The episode of adding to the specified volume of aqueous explosives It is mixed with such water of a particular solid material. 3. The method as requested by claim 1 consists of steps The moment of insertion of the blended explosives with a density reducer. 4. The method of claiming the right according to claim 2, which solid materials Specifically, they are selected from oxygen-rich salts, light metals and are self-explosive. 5. Method as requested by claim 3 which the thickness reducer Such tightness contains gas bubbles. Specific materials that avoid packing 6.Round mixer for the production of oil-mixed explosives. With water-in-oil insensitive water, consisting of (a) a cylindrical shell with a longitudinal axis, closed end and open end. For the material to be blended and for transferring the mixed material to the shell They have an internal diameter of at least 1.5 m and prefer more than 1.5 to 2.5 m. They can be rotated around the axis and (b) large numbers of blades that are tilted and placed at a distance from each other. On the inner wall of the shell, the blades were placed in line. Across the said core The blade is positioned So that when the shell's clockwise rotation, the flowing material inside the shell is moved towards the closed end. Of such shell And by turning counterclockwise, the material is moved And through the open end of the shell above the said protrusion The blade of the blade makes it possible to lift the material inside the shell to the top of the shell and drop the material by gravity. At the base of the shell at a drop velocity of 5 to 7 m / s 7. The mixer, as requested by claim 6, consists of a receiver adjacent to the open end of the shell for collecting oil-based explosives with water moving from the open end of the shell. Such shell The receiver has a steering device on the base. For delivering the collected ingredients to the need 8. Mixers as requested by claim, 6 lines, the inner diameter is 1.5 to 2.5 meters.
