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 sid

Example Embodiment

[0053] Attached below figure 1 The present invention will be further described in detail with the specific embodiments. as the picture shows:

[0054] The static sensitization technical method and device of emulsion explosives of the present invention pass through a pipeline-type sensitization tube with interlayer, the front end is connected with the emulsification matrix and the sensitizer delivery pipeline, and the back end is connected to a charging machine of a certain length The injection pipe is connected, and the sensitization pipe is installed in a certain order with 2-6 cone-shaped sensitization cups with holes and 1-5 mixers. The capacity is 2t / h-8t / h, and the temperature is 50℃~70℃. Under the combined action of pressure 0.8MPa~1.5MPa and foaming agents A and B, the emulsified matrix is ​​continuously mixed and sensitized to form a stable emulsion explosive. It is characterized in that the emulsified base and the sensitizer are mixed in a certain ratio, and when they ...

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...
