Description

IDAIDKA - DETONATOR

The inventive utility model relates to the field of industrial blasting explosives. A checker detonator is intended to initiate borehole charges of industrial explosives.

The experience of using detonator drafts in blasting operations at mining enterprises inevitably showed the need to use a plastic or cardboard case to protect the drafts from mechanical and thermal influences when loading a well and to preserve its integrity in the event of cracking. Such cases were introduced into the design of domestic cast detectors, for example, TG-P6 OS and TG-P850 TU 72G6-С02-07510000-99, TG-1ССОЛ-ПО, ТГ 1СССЛ-ПО ТУ 7288-Об6-0751050а-20С In such cases molded checkers-detonators are produced pits and companies Wltzo-Wo§e (/ (Sweden) and TeoLctn Cd po-gatlon (USA). These detonator drafts are already as a single unit - a case with an explosive charge placed in it.

The closest to the claimed Utility model is 1666 according to the application 2000117382/20 dated 03.07.2000 (the applicant is Biysk Oleum Plant). It, like all foreign and domestic detonator drafts. It provides for the explosives to be loaded directly into the case. As with all of them, it has on the end surface there is a recess connecting the channel and the socket, the purpose of which is to protect the waveguide with the cambric from damage during operation when it is bent.

However, casting a charge into a case with a small heat storage capacity from a material with low thermal conductivity (Polyethylene, cardboard) significantly lengthens the molding cycle in comparison with casting in a metal mold.

The recess in the checker, while protecting the waveguide, nevertheless does not protect the detonating cord from below when tying the detonator checker. At the same time, the recess is molded by the tool part, the most complex and labor-intensive to manufacture, which significantly increases the cost of filling equipment.

The purpose of the claimed utility model is to increase the productivity of the process of manufacturing checkers, simplify the process equipment and protect the detonating skin and waveguide by

the side is equipped with an annular protrusion (skirt) with cutouts for the detonating cord, and the lower end of the charge is made flat, with the inlet holes of the socket and channel, i.e. devoid of recess.

The charge can be made from any mixed explosive (TG, THF, pentolite).

Figure 1 shows the design of the inventive checker-detonator $ 1 where I is the body (glass with a lid), 2 is the explosive charge, 3 is the channel, 4 is the socket, 5 is the body skirt 3 here, an example shows a threaded connection of the body with the cover.

In Fig. 2 shows a diagram of the installation of the inventive checkers-detonator with detnyuyu cord, where I - checker-detonator, 2 - detonating cord.

The claimed design allows casting a charge in a metal mold, which, experiments show, reduces the molding cycle by 25 ... 30 compared to pouring directly into a non-metallic body. After that, the charge is inserted into the glass, which is closed by a lid.

The height of the skirt IC ... I2MK is quite sufficient to protect both the waveguide and the detonating cord loops.

At the same time, if necessary, the traditional technological option is not excluded - pouring explosives directly into the body.
