Abstract
The invention discloses an exciter for a detonating tube. The exciter for the detonating tube comprises a fixed part and an inserting part, wherein an inner thread is arranged at one end of the fixed part, and a fixed hole is formed in the other end of the fixed part. The fixed hole and the inner thread are communicated through a cavity. The inserting part is a circular cylinder, wherein an axis core is provided with a through hole. An outer thread which corresponds to the inner thread is arranged outside the inserting part, and the through hole of the inserting part is communicated with the cavity. According to the exciter for the detonating tube, a shock wave principle is utilized, and an electric firing component is placed inside a sealed cavity. A high-temperature shock wave is generated in the cavity by detonating the electric firing component, and thereby the detonating tube is detonated, and a detonator is set off. The exciter for the detonating tube is easy to achieve and capable of being reused, and thereby the detonating cost can be lowered.
Description
Technical field
The invention belongs to the explosion field, be specifically related to a kind of detonator exciter.
Background technology
Detonator claims again nonel tube.Scribble the plastic flexible pipe of composite explosives powder (explosive and metal powder mixture) for inwall.High-pressure polyethylene material by 1.5 millimeters of internal diameters, external diameter 3 millimeter is made, and the composite explosives proportioning is hexogen 91%, and aluminium powder and the common variable color detonator of other compositions 9%(primer proportioning are RDX75%:Al 25%), 14~16 milligrams/meter of coating doses.Can excite the initiations such as rifle and fire element by various detonators, primacord, percussion rifle, special use.Form a kind of special detonation after causing in pipe, its detonation wave is propagated with constant speed.It can only detonating primer and can not ignition charge, and propagation performance is good, and meet the fire burning and be not excited, strong shock resistance, water resistant and resistance to voltage are all good, and the tool some strength, and cost is low, generally uses.
At present, detonator is excited and mainly adopts electric arc or shock wave dual mode.The arc excitation method, under high pressure positive and negative electrode sparks, and often can cause two most advanced and sophisticated oxidations, and the metallic residue that produces at the chemical reaction that excites middle generation sticks to electrode surface, causes the difficulty in reusing; The employing shock-wave excitation, the shock wave that produces after existing multiplex electric cap or primacord blast excites detonator, causes cost increase in explosion.
Summary of the invention
The purpose of this invention is to provide a kind of being easy to and realize, can reuse, and the cheap detonator exciter of blasting cost.
Detonator exciter of the present invention comprises fixed part and insertion parts, and an end of described fixed part is provided with internal thread, and the other end of fixed part is provided with fixing hole, is communicated with by a cavity between described fixing hole and described internal thread; Described insertion parts is the cylinder that there is through hole in an axle center, and the insertion parts arranged outside has the external screw thread corresponding with described internal thread, and the through hole of described insertion parts is communicated with described cavity.
As optimization, described fixing hole is a bellmouth, and its aperture, outside is less than medial aperture.Its aperture, outside less than the diameter of fire element, can be fixed on fire element on fixing hole with fire element by its injection moulding part slightly.
Be provided with cyclic lug in the through hole of described insertion parts near an end of described cavity.Guarantee that detonator can not pass insertion parts, can prevent that detonator is slotting broken with the medicine head of fire element.
Be provided with spacing preiection section near the internal thread of described fixed part and described cavity junction.In the time of can guaranteeing that insertion parts is screwed into fixed part, can not touch the medicine head of fire element.The detonator exciter can adopt steel material to make.
During use, detonator is inserted in the through hole of insertion parts, fire element is fixed on fixed part, insertion parts is screwed into by its external screw thread in the internal thread of fixed part, insertion parts keeps certain distance near between the medicine head of an end with fire element of fixed part.Excite the medicine head of fire element by detonating power supply, the burning of medicine head produces the high temperature impact ripple, detonator can be excited.
Detonator exciter of the present invention utilizes the shock wave principle, and electric igniting assembly is placed in a closed cavity, by igniting electric igniting assembly, produces the high temperature impact ripple in cavity, thereby ignites detonator, band crash of thunder pipe.The present invention is easy to realize, can reuses, thereby can reduce blasting cost.

The detonator exciter as shown in Figure 1 and Figure 2, comprises fixed part 2 and insertion parts 1, and an end of fixed part 2 is provided with internal thread 4, and the other end of fixed part 2 is provided with fixing hole 5, is communicated with by a cavity 6 between fixing hole 5 and internal thread 4; Insertion parts 1 is the cylinder that there is through hole in an axle center, and insertion parts 1 arranged outside has the external screw thread 3 corresponding with described internal thread 4, and the through hole of insertion parts 1 is communicated with cavity 6.
Be provided with cyclic lug 9 in the through hole of insertion parts 1 near an end of cavity 6.Guarantee that detonator 7 can not pass insertion parts 1, can prevent that detonator 7 is slotting broken with the medicine head of fire element 8.
Be provided with spacing preiection section 10 near the internal thread 4 of fixed part 2 and cavity 6 junctions.In the time of can guaranteeing that insertion parts 1 is screwed into fixed part 2, can not touch the medicine head of fire element 8.
During use, detonator 7 is inserted in the through hole of insertion parts 1, fire element 8 is fixed on fixed part 2, insertion parts 1 is screwed into by its external screw thread 3 in the internal thread 4 of fixed part 2, insertion parts 1 keeps certain distance near between the medicine head of an end with fire element 8 of fixed part 2.Excite the medicine head of fire element 8 by detonating power supply, the burning of medicine head produces the high temperature impact ripple, detonator 7 can be excited.The detonator exciter can adopt steel material to make.
Detonator exciter of the present invention utilizes the shock wave principle, and electric igniting assembly is placed in a closed cavity, by igniting electric igniting assembly, produces the high temperature impact ripple in cavity, thereby ignites detonator, band crash of thunder pipe.The present invention is easy to realize, can reuses, thereby can reduce blasting cost.
