Explosive material impact and debris recovery device

Abstract

The invention discloses an explosive material impact and debris recovery device; a cylinder is equipped with a gas-pressure meter and a pressure regulating valve; a gun valve is placed in the cylinder, one end of a gun valve throat pipe is inserted into a gun valve casing pipe, the gun valve casing pipe is equipped with a vent valve port which can be sealed by a gun valve piston, and one end of the gun valve casing pipe is connected with a gas inflation valve and a pressure relief valve; the gun valve casing pipe is also equipped with air holes which can communicate with the gun valve casing pipe and the cylinder; one end of a launching pipe is fixed on the cylinder, a sample holder is placed in the launching pipe, and the other end of the launching pipe is equipped with a baffle cap; a recovery box is fixed on a target plate, the side face of the recovery box is equipped with a through hole, and a test sample passes through the through hole on the side face of the recovery box and isimpacted to the target plate when the test sample is divorced from the sample holder and is ejected out from the launching pipe. The device conveniently recovers debris after explosive impacting, andhas simple structure and low cost.

Description

technical field [0001] The invention relates to the field of identification and detection of explosives, and more specifically, the invention relates to an explosive material impact and debris recovery device. Background technique [0002] Whether the powder produced by the pulverization of unknown materials during impact is easy to be ignited by flames and burns rapidly is an important indicator for judging whether a material has an explosion hazard. The brittleness test is one of the hazard identification items of explosives. The brittleness test is to smash the tested sample at a certain speed, and then collect the impacted and crushed residue powder to conduct an explosive ignition test to detect whether it is easy to ignite and deflagrate, so as to identify its explosion hazard class. Therefore, accelerating the sample to a certain speed and collapsing it into pieces, collecting the crushed powder residue is the main process of the brittleness test for explosive hazard...
