The arms are connected to each other; the bottom end of the longitudinal valve stem 4 is provided with a tapered sealing plug 9;

[0033] The bottom surface of the medicament chamber 7 is provided with a number of injection nozzles 8 communicating with it, and the injection nozzles 8 and the tapered sealing plugs 9 are longitudinally fitted a...

Embodiment 2

[0043] As another embodiment of the present invention, the surface of the inner wall of the medicament chamber is provided with an antistatic coating to avoid static electricity and friction ignition; the surface of the longitudinal valve stem is also provided with an antistatic coating; the antistatic coating The first layer is obtained by spraying antistatic paint, and the thickness of the coating is controlled to be 0.5-1.0mm.

Embodiment 3

[0045]An antistatic coating, which is prepared according to the following process:

[0046] 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;

[0047] 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;

[0048] 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 filling device for a mixed agent in an initiator. The filling device comprises a support frame; the top of the support frame is provided with an agent chamber, and one end ofthe agent chamber is provided with a feed inlet; an insulating interlayer is arranged on the outer wall of the agent chamber; a longitudinal valve rod is arranged inside the agent chamber; the top end of the longitudinal valve rod is connected with a telescopic arm of an adjustable stroke cylinder; conical sealing plugs are arranged at the bottom end of the longitudinal valve rod; and the bottomsurface of the agent chamber is provided with an agent injection nozzle, and the agent injection nozzles are respectively longitudinally attached and correspond to the conical sealing plugs. Accordingto the filling device, the working temperature of the agent can be ensured, and the flowability is ensured to be beneficial to the flow of the agent injection. A corrugated rubber sleeve is arrangedat the joint of the longitudinal valve rod and the inner wall of the agent chamber, so that when the longitudinal valve rod moves up and down, the leakage of the liquid agent is effectively prevented,and the safety is improved. The agent chamber and the longitudinal valve rod are made of stainless steel, so that the filling device has the beneficial effects of not firing, conducting electricity or generating static electricity, and the safety of the agent in the operation process is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of explosive filling equipment, and in particular relates to a filling 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 t...
