| abstract |
The present invention relates to a detonation cutter device for pumping explosives in bulk comprising: a tube 1 in the form of a loop delimited by 2 portions of tube 2,3 which intersect, a hammer 4 interposed between the 2 portions of tube 2,3 in contact with them, an anvil 5 located in contact with one (2) of the 2 tube portions 2,3 opposite the hammer 4, so that this tube portion 2 is sandwiched between the hammer 4 and the anvil 5. This device makes it possible to stop a detonation even for explosives of small critical diameter, less than 25 mm. The invention also relates to a circuit for pumping bulk explosives comprising such a device, loading cannulas, an explosives tank and a pump. |
