Method and device for static sensitization of emulsion explosives

Abstract

The invention provides a method and device for static sensitization of emulsion explosives. According to the invention, a tubular sensitizing pipe with an interlayer is arranged; the front end of the tubular sensitizing pipe is connected with an emulsifying matrix and sensitizer conveying pipe; the rear end of the tubular sensitizing pipe is connected with an explosive injecting pipe of a charging machine and with a certain length; the interior of the tubular sensitizing pipe is provided with, according to a certain sequence, 2 to 6 cone-type sensitization cups with holes and 1 to 5 mixers; and under the conditions of production capacity of 2-8 t / h, a temperature of 50-70 DEG C, a pressure of 0.8-1.5 MPa and co-action of foaming agents A and B, the emulsifying matrix is continuously mixed and sensitized so as to form a stable emulsion explosive.

Description

1. Technical field: [0001] The invention relates to the production field of emulsion explosives, in particular to a static sensitization technology of emulsion explosives, in particular to a static sensitization technology method and device of emulsion explosives. 2. Background technology: [0002] Water-in-oil emulsion explosive has become the main variety of domestic industrial explosives due to its remarkable explosive performance and safety performance. The sensitization method is divided into mechanical stirring and non-mechanical stirring, namely dynamic sensitization and static sensitization. There are two types of sensitization: physical sensitization and chemical sensitization. Because physical sensitization uses porous solid particulate matter as the sensitizing substance, it is affected by the cost or strength of the material, and it is an inert substance that does not participate in the explosive reaction and affects the explosive force. Chemical sensitization is...

Problems solved by technology

However, the structure of the device is complicated, it is honeycomb-shaped, it is easy to block and shut down, and it is inconvenient to disassemble and clean. The shearing of the cutting blade body easily destroys the sensitization bubbles, which affects the sensitization effect. There is no hot water circulation layer, and the low-temperature sensitization effect is insufficient. Good, easy to form waste medicine when starting up

[0004] Chinese patent CN103304348A also discloses "A Static Sensitization Method and Equipment for Packing Emulsion Explosives", in which the latex matrix and sensitizer are sprayed to the side wall through multiple rows of injection holes through the action of external force, resulting in collision and mixing to form an emulsion explosive , but the structure of the device is complicated, multi-stage sensitization is connected in sections, it is not easy to disassemble and wash, there is no hot water interlayer, the initial sensitization time is long, waste medicine is easy to be formed in the early stage of starting up, and the production process is easy to block and cause shutdown. The actual use effect of the device is very good Unsatisfactory, its inventors no longer use this method in technology transfer
