Abstract

The utility model discloses a split assembly type detonator, which comprises detonator casings, brisance explosive, initiating explosive, delay powder and powder, wherein the brisance explosive, the initiating explosive, the delay powder and the powder are buried in the detonator casings. The powder is connected with a pin line led out of the detonator casing, the initiating explosive, the delay powder and the powder serve as an initiation section, and the brisance explosive serves as a detonating section of the detonator. The split assembly type detonator is characterized in that the initiation section and the detonating section are respectively buried in two separated detonator casings, and a connection matching structure is arranged between the two separated detonator casings. By adopting split design of the initiation section and the detonating section, the initiation section and the detonating section are separated during production, transport and storage, so that the problem of major accidents caused by integrality of the initiation section and the detonating section of the existing detonator is solved. During initiation, the initiation section and the detonating section are assembled to achieve connection, and then the split assembly type detonator can be used as the traditional detonator. The split assembly type detonator has a stable initiation function.

Description

The packaging detonator of a kind of split

Technical field

The utility model relates to the ignition equipment, the packaging detonator of particularly a kind of split.

Background technology

Detonator is widely used as the main apparatus to cause bursting of explosive; Its primary structure is in Can, to bury high explosive, priming, delay powder and medicine head successively underground; The medicine head connects payment to a porter and draws Can; Wherein priming, delay powder and medicine head are as priming device, and high explosive is the primer of detonator; Light the medicine head through the payment to a porter energising during use; The medicine head is lighted delay powder, and delay powder is lighted priming, and priming is ignited and produced detonation wave; Detonation wave propagates into high explosive and makes the high explosive detonating primer; Existing detonator is integral type, and its high explosive, priming, delay powder and medicine head are placed in the same shell simultaneously, is producing, can cause security incident because of safe sensitivity problem such as bump, static or friction in transportation and the process of storing; When the electrostatic breakdown metal shell, can make the high explosive of the high quick-fried ability of the interior low sensitivity of priming detonating primer of the low quick-fried ability of high sensitivity cause huge personnel, property loss.That is to say that the priming in the detonator very easily is detonated, but the energy that detonates is low especially; If the priming blast just in the detonator, power is very little so, and is very little to people's injury; Can not cause big loss, the power of high explosive is very big, but it is difficult for self-destruction; Have only the external world to give just can make its blast when sizable energy stimulates, if priming and high explosive effect then can cause heavy losses by the very big energy of abrupt release.

The utility model content

The purpose of the utility model is to provide a kind of packaging detonator of split of the function-stable that detonates, and is intended to solve traditional detonator high problem of risk factor when producing, transporting and storing.

The purpose of the utility model is achieved through following technical scheme; The packaging detonator of a kind of split comprises shell and buries high explosive, priming, delay powder and the medicine head in the shell underground that the medicine head connects payment to a porter fairlead shell; Wherein priming, delay powder and medicine head are as the section of detonating; High explosive is characterized in that as the ignition section of detonator: the said section of detonating is embedded in respectively in two shells that separate with the ignition section, is provided with the connection fit structure between said two separation shells.

Connection fit structure between said two separation shells is for being threaded.

Said two connection fit structures that separate between the shell connect for engaging.

The utility model is taked the section of detonating and is ignited section split design; Two parts separate in production, transportation and storage process; Solved the problem that two sections one of existing detonator cause major accident easily well; When igniting two sections assemblings are connected just used the same with traditional detonator of back, function-stable detonates.

The specific embodiment

As shown in Figure 1, the detonator that the utility model provided is divided into the section of detonating and ignites section, and two sections are separated in production, transportation and the storage process; Two sections connect use during ignition, and connected mode is taked to be threaded, and the section of detonating comprises payment to a porter 1, bayonet socket plug 2, medicine head 3, delay powder 4, priming 5, inner casing 7 and shell 8; Ignite section and be made up of shell 9 and high explosive 6, delay powder 4 is compressed on earlier in the inner casing 7 with priming 5, inner casing is packed into detonate in the shell 8 then; The end of payment to a porter 1 connects medicine head 3, and payment to a porter 1 is set in the bayonet socket plug 2, at last bayonet socket plug 2 is packed in the shell 8; Compacting is reinforced to bayonet socket then, and in conjunction with shown in Figure 2, the lower end of shell 7 is provided with external screw thread 10 with an ignition section junction; In conjunction with shown in Figure 3, high explosive 6 is pressed into column in advance, and a powder charge and two times powder charges are pressed into solid standard body respectively; Shell 9 inner sealings of packing into, shell 9 epimere inwalls are furnished with and are connected the internal thread 12 that cooperates with external screw thread 10.The section of detonating can also take to engage connected mode with being connected of ignition section.Shell 8 can use according to conventional detonator after reinforcing with PVC tape 11 with shell 9

junctions.Shell

8,9 adopts nonmetallic materials (like safety glass) to be processed to form the thick hard shell of about 2mm, and its hardness satisfies the tying requirements of detonator, guarantees the binding character of detonator, and thin excessively then binding character is not strong, the blocked up effect of detonating that then influences detonator.

The utility model takes in production, transportation and the storage process two sections to separate; Two sections connect use during ignition; Guarantee binding character; Detonator is normally detonated, the safety problem that risk factor is high, destructiveness is strong when high explosive co-production, the transportation, the storage that have solved the priming of the low quick-fried ability of high sensitivity in the existing detonator and the high quick-fried ability of low sensitivity; Use anti-electrical property better and relatively to replace traditional metal shell than cheap nonmetallic materials shell; Improve security, practiced thrift production cost; And non-metal shell is compared than metal shell; It is antistatic, strays, thunder and lightning, electromagnetic wave and high-frequency signal ability significantly improve, and has improved intrinsic safety.

The section of detonating is used for detonating and prangs the high explosive in the powder column, reaches the stable ignition effect of detonator, when detonating; The medicine head is lighted in the payment to a porter energising; The medicine head produces focus combustion delay powder, and delay powder is lighted priming, and priming detonation generation detonation wave propagates into high explosive makes the high explosive detonating primer.

The foregoing description only is the preferred embodiments of the utility model; The technical conceive and the essential implementation of the utility model have been specified; Be not to be that protection domain to the utility model limits; All any simple modification and equivalent structure transformation or modifications of being done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
