Abstract

The invention provides acoustic resonance mixing equipment with a labyrinth-shaped mixing channel and an explosive mixing technology.The equipment comprises an equipment support and an acoustic resonance platform, a plurality of solid-liquid feeding devices are installed on a cross beam of the equipment support, and the labyrinth-shaped mixing channel is installed on the upper platform face of the acoustic resonance platform; a labyrinth-shaped mixing channel is formed in the upper platform surface, a feeding channel is detachably formed in the center of the labyrinth-shaped mixing channel, a discharging device is mounted in the middle of the upper platform surface, the top end of the discharging device is adjacent to the labyrinth-shaped mixing channel, and a receiving device is arranged below the bottom end of the discharging device. When the acoustic resonance mixing equipment with the labyrinth-shaped mixing channel is used for mixing, the flowing direction of an explosive material can be repeatedly changed by the labyrinth-shaped structure, so that a relatively large velocity gradient and turbulent pulsation are formed in the explosive material, and the explosive material is separated from the explosive material under the action of shear force formed by the velocity gradient and the turbulent pulsation. The optimal mixing effect can be realized.

Description

technical field [0001] The invention belongs to the technical field of explosive mixing, and relates to explosive mixing equipment and an explosive mixing process, in particular to an acoustic resonance mixing equipment with a labyrinth-shaped mixing channel and an explosive mixing process. Background technique [0002] Explosives, as the power and energy for weapon propulsion, launch, and damage, are one of the important parts common to all kinds of weapons and equipment, and are the key factors for weapons and equipment to achieve efficient damage. They are still irreplaceable at present and in the foreseeable future. From the earliest invention of black powder to the birth of Hessogen at the end of the 19th century, and to the mid-20th century when Oktokin entered the practical stage, with the continuous improvement of explosives in terms of energy, performance, and safety, its components It is also becoming more diverse. PBX is a kind of mixed explosive with special req...
