Embodiment 2

[0037] As another embodiment of the present invention, the inner wall surface of the stirring tank is provided with an antistatic coating to avoid static electricity and friction ignition; the surfaces of the parts in contact with the mixed medicament are provided with an antistatic coating; the The antistatic coating is obtained by spraying the antistatic coating, and the thickness of the coating is controlled to be 0.5-1.0mm.

Embodiment 3

[0039] An antistatic coating, which is prepared according to the following process:

[0040]Dissolve acrylic resin and polyarylsulfone in dimethyl sulfoxide, stir at room temperature for 30 minutes, then add dimethyl silicone oil, and continue stirring for 15 minutes to obtain the main ingredient; acrylic resin, polyarylsulfone, dimethyl sulfoxide and dimethyl silicone oil The mass ratio is 2:1:10:3;

[0041] Mix nano-talc powder, nano-graphite and nano-boron carbide evenly to obtain a mixture, then add it to twice the weight of purified water, stir evenly, then add hexamethylcyclotrisiloxane, heat up to 60°C, ultrasonic (frequency 20KHz ) was dispersed for 5 minutes to obtain auxiliary materials; the mass ratio of nano-talc powder, nano-graphite, nano-boron carbide and hexamethylcyclotrisiloxane was 1:2:1:10;

[0042] Add the auxiliary materials to the main material at a mass ratio of 1:4, stir at a speed of 500rpm for 10 minutes, make it evenly mixed, and seal the package. ...

Abstract

The invention discloses a stirring device for mixing medicaments inside the detonator, which comprises a stirring tank; the top of the stirring tank is provided with a hydraulic motor connected to the stirring shaft; the stirring shaft is sequentially provided with positive Propeller blades, reverse propeller blades and anchor paddles; the top of the stirring tank is provided with a dust removal port, a liquid material feed port and a powder material feed port respectively; the top of the stirring tank is provided with a thermometer installation pipe; the stirring tank The outer wall of the body is provided with a water interlayer; the outer wall of the water interlayer is provided with an insulating layer; the bottom of the stirring tank is provided with a discharge pipe. The discharge performance of forward propeller blades is good, the shear force is low, it is in a convective circulation state at low speed, and it is in a turbulent dispersion state at high speed, which can make the agitator reach a higher flow field in transitional flow or even turbulent flow, and can put the input The powder material is immediately pressed into the liquid material. The reverse propeller blades in the middle layer fully mix the input powder. The lower layer is an anchor paddle to prevent powder from settling.

Description

technical field [0001] The invention belongs to the technical field of stirring equipment, and in particular relates to a stirring device for mixing medicaments inside a detonator. Background technique [0002] In the prior art, the priming charge refers to a sensitive explosive that burns under the action of relatively weak external excitation energy and can rapidly transform into a detonation. Its high sensitivity and short detonation growth period are used to detonate strong explosives, so it is also called primary explosives. It can be divided into single substance primer, mixed primer and double salt primer; according to the excitation mode, it can be divided into acupuncture medicine, percussion medicine, friction medicine and conductive medicine. It is used to fill various detonating devices and as the initial charge of explosive devices. [0003] The primary explosives inside the current detonators are mostly made of TNT and RDX mixed with each other, and the mixin...
