A kind of granular ammonium oil explosives production equipment

Abstract

The invention discloses a granular ammonium nitrate fuel oil explosive production device. The granular ammonium nitrate fuel oil explosive production equipment comprises a hopper pipe type screw conveyor arranged on a rack. The tubular screw conveyor consists of a first tubular screw conveyor and a second tubular screw conveyor; the first tubular screw conveyor is connected with a diesel sprayingsystem; wherein a feed port of the first tubular screw conveyor is connected with a discharge port of the hopper, a discharge port of the first tubular screw conveyor is connected with a distributor,the distributor is provided with a first outlet and a second outlet, the first outlet is connected with a feed port of the second tubular screw conveyor, and the first outlet and the second outlet isopened alternatively. When the second outlet is opened, the porous granular ammonium nitrate fuel oil explosive is output to the outside. The second tubular screw conveyor is connected with an emulsion matrix pipeline, and a discharge port of the second tubular screw conveyor outputs emulsified granular ammonium nitrate fuel oil explosives. The production equipment has the production capacity of two kinds of granular explosives, is compact in layout, facilitates overall carrying and site transferring and can achieve continuous production.

Description

technical field [0001] The invention belongs to the technical field of civil explosives, and in particular relates to production equipment for granular ammonium oil explosives. Background technique [0002] At present, there are two main production methods for granular ammonium oil explosives. One is to use ground auxiliary facilities, such as water-oil phase preparation system, emulsification system, porous granular ammonium nitrate feeding system, etc., to cooperate with the production of on-site mixed explosives trucks, and on-site mixed explosives Although the mobility of the car is strong, the investment is large and the production cost is high; the second is to use the tank-type mixing method to produce in the fixed factory building, use the screw feeder to transfer the material, and use the powder filling machine for packaging. This method has the problem of not being able to produce continuously, as well as the disadvantages of large investment in production equipmen...
