Abstract
The invention discloses a pressure collecting type detonating pill. The detonating pill comprises a shell and initial explosive received inside the shell; and the initial explosive consists of 8 to 12 weight portions of potassium nitrate, 1 to 3 weight portions of sulfur and 2 to 5 weight portions of aluminium powder. The shell is one of a paper cylinder or a plastic cylinder; the inside diameter of the shell is between phi 6 and 15 mm; the length of the shell is between 50 and 60 mm; and the weight of the initial explosive in the shell is between 3 and 10 grams. In use, the pressure collecting type detonating pill and an ignition device are connected and are put into a closed space with the explosive together; the explosive is filled in the space; and the ignition device is ignited and can detonate the explosive. The detonating pill is the pressure collecting type ignition device and does not explode by self in an unsealed space at normal atmosphere; even if the detonating pill and loose explosive are put together and the detonating pill is ignited, the loose explosive cannot be detonated. Therefore, the pressure collecting type detonating pill is quite safe in the process of manufacture, storage, transportation and use, has low cost, avoids the possibility that common detonator is accidentally impacted and possibly causes explosion when the explosive and the detonator are mounted.
Description
Technical field
The present invention relates to a kind of device of fired charge, and the making and use method of this device.
Background technology
At present, cutting into a mountain for quarrying in the society all is to stamp borehole on the rock of massif in advance, the detonator of explosive and fired charge is filled out to be put in the borehole then.Light the shock wave that causes by blasting cap detonation behind the detonator with explosive initiation.So be unable to do without detonator in the civilian igniter.The detonator of prior art has copper detonator, paper case detonator etc.Detonator belongs to explosives, when it is subjected to bump, vibrations, all may blast, itself just have very big lethal, from producing detonator, transportation detonator to using detonator, each link is all abnormally dangerous, and is careless slightly, will lead to huge disaster, will threaten to composition of society if allow the lawless person control these class article.
Chinese patent 86102717 once disclosed a kind of industrial detonator using no priming charge, and used alms giver's medicine is not for containing the pyrotechnic composition of priming explosive.Variety of ways such as available safety fuse, electric igniter, primacord or delay powder are ignited.It includes housing, have the interior pipe of flash hole, alms giver's medicine, transitional medicine, secondary explosive, damp-proof membranes, fixing in the lacquer or the glue of pipe.Alms giver's medicine is by two kinds or three kinds of three kinds of components of combustiblematerials (comprising magnesium powder, aluminium powder, boron powder, zirconium powder, plumbous rhodanate, lead ferrocyanide etc.), oxygenant (comprise potassium perchlorate, cross chloric acid by, tri-lead tetroxide, lead peroxide, barium peroxide, zinc peroxide, saltpetre etc.) and high explosive (comprise melanocyte gold, too the metal-salt of peace, octogen, modification 662 explosives or explosive), adds priming charge and tackiness agent and feels a kind of in the agent or two kinds immediately and mix.Its priming charge is the boracic priming charge or contains the zirconium priming charge or siliceous priming charge or contain the magnesium priming charge or titaniferous priming charge or black powder.
Chinese patent 87104857.4 is disclosed also to be the detonator of fired charge, they by the shell of metal or nonmetal (paper or plastics) with in igniting pipe form.Its used medicine comprises priming charge and high explosive (PETN or RDX), can adopt primacord, electric igniter and fuse detonation.Chinese patent 86207685 also discloses a kind of polyvinyl chloride shell detonator of fired charge.Replace existing capsular shell to make detonator with polyvinyl chloride pipe, in the polyvinyl chloride raw material, add additive by weight ratio and produce shell, keep the stability of polrvinyl chloride structure, shell is applied the SN finish, eliminate its static hazard, a powder charge directly is pressed into the hexogen powder column in shell.
These the above-mentioned capsular structures and the proportioning of medicine be more complicated all, and detonator itself all has very strong blast ability, has very big lethally, all has unsafe factor in manufacturing, transportation, storage, the use.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of safe, device and using method thereof of not having the fired charge of blast ability and lethality at conventional environment.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
Pressure collection type detonation apparatus, as well comprises housing, is contained in the intravital priming charge of shell, and wherein priming charge comprises saltpetre, sulphur and aluminium powder.
The weight proportion of above-mentioned priming charge is: 8～12 parts in saltpetre, 1～3 part in sulphur, 2～5 parts of aluminium powders.Its best proportioning is 10 parts in saltpetre, 2 parts in sulphur, 3 parts of aluminium powders.
Above-mentioned housing is the wherein a kind of of paper web or plastic barrel, and it is of a size of internal diameter Φ 6～15mm, and length is 50～60mm.
The manufacture method of pressure collection type detonation apparatus, as well is: paper web or the plastic barrel of making corresponding size, each composition of weighing priming charge and mixing in proportion, priming charge is packed in paper web or the plastics tubing, and with the sealed at both ends packing of housing, wherein an end will seal with building paper then.Pack into about priming charge 3～10g in each tube.
The using method of pressure collection type detonation apparatus, as well is: connect portfire during use in pressure collection type detonation apparatus, as well, then pressure collection type detonation apparatus, as well and explosive are placed in the enclosed space (as borehole of accomplishing fluently) together, and tamp, the portfire of igniting outside safe distance gets final product fired charge.
Owing to adopted technique scheme, the obtained technical progress of the present invention is:
General detonator is by vibrations and fired charge, so just may cause the capsular blast if any accidental impact when laying explosive and detonator, and fired charge.Detonation apparatus, as well of the present invention is a kind of igniter of pressure collection type, is by the pressure after the priming charge burning explosive to be fired in enclosed space.It is under normal pressure, and in the unsealed space, self can not explode, even this detonation apparatus, as well and loose explosive put together and light this detonation apparatus, as well, and can not be with loose explosive initiation.Therefore manufacturing of the present invention, storage, transportation and use are all as safe as a house, and cost is very low.
Each composition low price of the priming charge that it is used, the source is sufficient; It only needs to use paper web or plastic barrel needn't use metal shell splendid attire priming charge, has therefore further reduced production cost.And manufacturing processed of the present invention is simple, and is easy to use.
