Exciter for detonating tube

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 [0001] The invention belongs to the field of blasting, and in particular relates to a detonator exciter. Background technique [0002] Nonel, also known as non-electric nonel. A plastic hose whose inner walls are coated with mixed explosive powder (a mixture of explosive and metal powder). It is made of high-pressure polyethylene material with an inner diameter of 1.5 mm and an outer diameter of about 3 mm. The proportion of the mixed explosive is 91% of RDX, 9% of aluminum powder and other ingredients (the proportion of the detonating charge of the ordinary color-changing detonator is RDX75% : Al 25%), the coating dosage is 14-16 mg / m. It can be triggered by various detonators, detonating cords, firing guns, special firing guns and ignition components. After initiation, a special detonation is formed in the tube, and its detonation wave propagates at a constant speed. It can only detonate the detonator but not explosives. It has good propagation performa...

AI Technical Summary

Problems solved by technology

The arc excitation method, the instantaneous discharge of the positive and negative electrodes under high voltage often leads to the oxidation of the two tips, and the metal residue produced by the chemical reaction in the excitation adheres to the surface of the electrode, causing difficulties in re-use; using shock wave excitation, The shock wave generated after the explosion of the electric detonator or the detonating cord is mostly used to excite the nonel, resulting in an increase in the cost of blasting
