Abstract

The invention discloses a stirring device for mixing chemicals inside an initiation tool. The device comprises a stirring tank body, wherein a hydraulic motor which is connected with a stirring shaftin a transmission mode is arranged at the top of the stirring tank body, the stirring shaft is provided with a forward propeller blade, a reverse propeller blade and an anchor-type propeller blade sequentially from top to bottom, and a dust removing mouth, a liquid material feeding mouth and a powder material feeding mouth are formed in the top of the stirring tank body separately; the top of thestirring tank body is provided with a thermometer mounting pipe, a water interlayer is arranged on the outer wall of the stirring tank body, and a heat insulating layer is arranged on the outer wall of the water interlayer; and a material discharge pipe is arranged at the bottom of the stirring tank body. The forward propeller blade has good discharge performance and low shear force, is in a convective circulation state at low speed and in a turbulent dispersion state at high speed, and is capable of enabling a stirrer to reach a high flow field during transitional flow or even turbulence, andpowder which is put into the stirrer can be immediately pressed into a liquid material; and the input powder can be mixed thoroughly through the reverse propeller blade in the middle layer, and precipitation of the powder can be prevented through the lower-layer anchor-type blade.

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...
