Description
Technical Field
The invention relates to the technical field of digital electronic detonators, in particular to a digital electronic detonator powder head and a production method thereof.
Background
The digital electronic detonator is an electric detonator which utilizes an electronic control module to control the detonation process of the detonator. The electronic control module is arranged on a built-in chip of the digital electronic detonator, and performs the functions of self performance detection, initiation delay time control, ignition energy control, detection of an internal identity information code of the detonator and the like through external initiation equipment, so that the circuit module for communicating and controlling initiation of the detonator and the external control equipment is realized. In the detonation control process of the digital electronic detonator by the external detonation equipment, the electronic control module is firstly detected by the external equipment, and the built-in identity information code and the detonation password are determined to be correct. After the detection is correct, the device charges the patch capacitor on the built-in chip of the digital electronic detonator, and the capacitor discharges to ignite the bridge wire at the front part of the chip, so as to ignite the ignition powder head contacted with the bridge wire, thereby realizing the control on detonator initiation. The digital electronic detonator has the advantages of instrument inspection of the detonation network, high delay accuracy, controllable detonator information, controllable explosion time and the like due to the electronic control module.
After the detonator built-in chip is subjected to the ignition powder dipping and drying process, a water drop-shaped ignition powder head is formed at the head of the chip. And then the chip with the ignition powder head is transported to different sites, the working procedures of coating moisture-proof paint, welding leg wires, bayonet base detonators and the like are carried out, and finally the finished detonator is formed by binding three codes. However, when the ignition powder is dipped, gaps or small bubbles may exist at the contact points of the ignition powder and the bridge wire on the chip; meanwhile, in the working procedures of welding the leg wire and the like, the ignition powder head is possibly broken due to transportation and other factors, and the factors can lead to the defect of the ignition powder head. The size of the detonator built-in chip is limited by the size of the basic detonator, so that the volume of the detonator built-in chip is not excessively large. Therefore, the size of the capacitance on the chip is correspondingly limited, and only thin bridge wires which are easier to ignite can be selected. When a defective ignition plug is encountered, the energy released by the fine bridge wire is limited and the ignition plug cannot be effectively ignited. The digital electronic detonator containing the defective explosive head is still normal in circuit detection, and the internal condition is not easy to observe by naked eyes, so that the digital electronic detonator cannot be easily detected in production. However, when the explosive is used on site, the explosive cannot be detonated normally, engineering errors such as "blind gun" are generated, and huge economic loss is caused.
Aiming at some technical problems existing in the production of the ignition powder head of the existing digital electronic detonator, part of manufacturers sleeve the ignition powder head into a silica gel sleeve after the moisture-proof paint is coated on the ignition powder head in the production of the digital electronic detonator, and then remove the ignition powder head when the digital electronic detonator is bayonet-base. The method can effectively avoid the breaking of the ignition powder head in the production process, but increases the production steps, and can not avoid bubbles or gaps generated between the ignition powder head and the bridge wire in the dipping process. Some solutions are proposed in the prior patent literature, for example, a Chinese patent with the application number of 201020652696.3 discloses an electric detonator powder brushing machine, automatic mechanical equipment is selected to brush the detonator powder, and the consistency, the safety and the automation degree of the quality of products are improved. And has strong applicability and little change to the existing production mode and production process. The scheme is helpful for improving the quality of the ignition powder head, but the problem that the digital electronic detonator chip possibly generates a defective powder head in the powder dipping process is still to be improved, and meanwhile, the protection scheme of the ignition powder head in production is not mentioned.
With the improvement of the reliability requirement of the digital electronic detonator, the reliability requirement of the ignition powder head of the digital detonator is also increased. The problems that an air gap or small bubbles exist between an electric bridge wire and ignition powder, and the powder head is broken due to factors such as transportation and the like possibly caused by the traditional medicine dipping mode are to be solved better. Therefore, development of a novel digital electronic detonator head and a production method thereof are urgently needed to effectively solve the problem that the digital electronic detonator ignition head may have defects.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention provides the digital electronic detonator powder head and the production method thereof, which can provide a protective layer for the ignition powder head, improve the ignition capability of the ignition powder head on a basic detonator and improve the delay precision while improving the contact performance of the ignition powder and an electric bridge wire, and solve the problems of air gaps or small bubbles between the electric bridge wire and the ignition powder generated in the traditional ignition powder head during powder dipping. Meanwhile, the problems of crushing of the explosive head caused by factors such as transportation and the like and the quality of detonator products caused by ignition of the explosive head are reduced, and the defects of the prior art can be effectively overcome.
The technical problems to be solved by the invention are realized by adopting the following technical scheme.
A digital electronic detonator head and its production method comprises a drug injection device and a hose. The injection device comprises a main body part and a pressing plug, and is used for injecting ignition powder into the hose. The main body part is provided with a pressing plug inlet, a charging chamber and an ignition powder outlet. The said pressing plug inlet is correspondingly connected with the pressing plug, and is used for providing the inlet of the pressing plug into the main body part, so that the pressing plug provides the pressure for igniting the explosive in the explosive charging chamber. The upper part of the powder charging chamber is provided with a pressing plug inlet and a lower part connecting point powder outlet, and the powder charging chamber is provided with a large cavity for temporary storage of ignition powder. The ignition powder outlet has smaller caliber and is used for discharging the ignition powder in the charging chamber. The pressing plug is connected with the upper part of the main body part and can do reciprocating motion in the charging chamber, and is used for providing pressure for ignition powder in the charging chamber to flow out.
The hose can be connected with the gunpowder outlet and is used for storing ignition powder. After being cut into sections, the hose can deform under pressure to be connected with the built-in chip of the digital electronic detonator, so as to reduce the impact pressure applied to the ignition powder head and restrict the formation of the ignition powder head. Can provide restraint when the chip is inserted, ensure that the ignition powder does not spread around, and restrain the flame direction generated by the ignition powder after ignition.
When in use, the ignition powder is placed in the charging chamber of the main body part. The amount of pressure provided by the tamponade is determined by the nature of the powder formulation. According to the working requirement, the acquisition mode of the plug pressing power is determined, and manpower, electric energy and other forms of energy sources can be selected. And selecting the inner diameter size of the hose according to the size of the built-in chip of the digital electronic detonator. Under the pressure provided by the plunger, the temporarily stored ignition charge in the charging chamber is pressed out from the ignition charge outlet and into the hose. Then cutting the hose to a proper length according to the formula of the ignition powder and the conditions of the required ignition powder quantity. Inserting the built-in chip of the digital electronic detonator from the top of the cut hose until the bridge wire on the chip is close to the bottom of the hose.
Compared with the prior art, the invention has the beneficial effects that when the ignition powder in the hose enters the hose from the ignition powder outlet, the ignition powder is more effectively attached to the bridge wire due to the constraint of the hose wall, so that the formation probability of gaps and small bubbles is effectively reduced. Meanwhile, when the bridge wire on the built-in chip of the digital electronic detonator is inserted into the hose, the bridge wire can be fully contacted with the ignition powder, so that an air gap and small bubbles can be effectively reduced, the ignition powder can be effectively ignited by the bridge wire, and a defect ignition powder head is avoided. At the same time the bridge wires fire from the bottom of the hose, the flame propagation direction will propagate towards the primary under the constraints provided by the hose to better detonate the primary in the base detonator. Compared with the traditional drop-shaped explosive head, the hose can restrict the flame direction, and plays a better role in detonating the primary explosive in the basic detonator. Meanwhile, the quantity of the ignition powder can be adjusted by changing the size of the hose cut, so that the quantity of the ignition powder can be controlled more accurately than that of the traditional powder, and the second quantity of the digital electronic detonator is more accurate. The hose does not need to be removed, and the hose is detonated and destroyed together with the digital electronic detonator, so that the operation steps are fewer, and the production cost is reduced.
