Problems solved by technology

[0004] Since the detonator products are required to have the characteristics of high charge density, high detonation sensitivity, fast detonation speed, and high power, the detonating main charge of the detonating device product is a mixture of two high-energy explosives, and the detonating main charge itself requires Has lightning sensitivity, resulting in high product cost
The existing detonator injection products are all pouring the main charge into the paper shell matched with the metal mold, which leads to a long cooling time for the product, increased unsafe factors for mold removal, and seriously affects the production efficiency of the product

Abstract

The invention concretely relates to a primer with structure safety and an assembling process thereof, and belongs to the technical field of blasting equipment. The invention aims to solve the technical problem so as to provide the primer with high essential safety, and the excellent assembling process with safety, high efficiency and low cost. The invention adopts the technical scheme that the primer with structure safety comprises a shell, a priming drug box, a main charge and an upper cover, wherein the shell structurally comprises a wire through pipe, a detonating fuse through pipe, a detonator blind tract, a support positioning plate and an energy gathering hole; the shell is of a columnar structure which is opened in the upper end and sealed in the lower end; the wire through pipe, the detonating fuse through pipe, the detonator blind tract and the support positioning plate of the shell are integrally formed; the upper cover and the shell form a sealed cavity; the main charge is filled in the cavity; and the priming drug box is arranged above the support positioning plate. According to the primer with structure safety and the assembling process thereof provided by the invention, through the structure design of the shell, high essential safety, high water resistance and favorable processability of the primer product are realized.

Description

technical field [0001] The invention relates to the technical field of blasting equipment, in particular to a structurally safe detonator and an assembly process thereof. Background technique [0002] The detonator is used as a detonating source for mine blasting, engineering blasting, underwater blasting and large-scale open-pit coal mine blasting. [0003] The structure of the detonator in the prior art is composed of three parts: the shell, the main charge of the detonator, and the detonator column. The product has a detonator hole and a wire hole. When excited, the detonator in the detonator hole is used to excite the detonator. The main charge achieves the effect of the overall explosion of the detonator, thereby detonating the insensitive explosive, so that it can quickly achieve the effect of stable detonation. [0004] Since the detonator products are required to have the characteristics of high charge density, high detonation sensitivity, fast detonation speed, and...
