Description

Technical Field

[0001] This invention belongs to the field of civil blasting, and specifically relates to a civil continuous detonation explosive canister and a method for blasting. Background Technology

[0002] my country's industrial explosives mainly include aqueous emulsion explosives, porous granular ammonium nitrate explosives, and expanded ammonium nitrate explosives. Their main components are high-energy compounds containing C, N, and O elements, including ammonium nitrate (AN), oils (R-CH3), trinitrotoluene (TNT), and cyclotrimethylenetrinitramine (RDX). Upon detonation, they produce a three-phase aerosol system with explosive particles and microdroplets as the dispersed phase and explosive gases as the dispersion medium. The gaseous components include large amounts of N2, CO2, H2O, as well as high-risk components such as NOx, CO, and volatile organic compounds (VOCs). The particles originate from mineral dust, blasting material fragments, and the solidification phase transition process of explosive products. The microdroplets originate from the condensation phase transition process of explosive water vapor and the water mist dust suppression measures typically implemented at the blasting site.

[0003] With the widespread application of engineering blasting technology in infrastructure construction and resource extraction, the extensive use of explosives inevitably brings health and environmental risks, among which aerosol pollution from blasting projects is particularly prominent. Furthermore, with the increasing demand for deep tunneling in infrastructure construction, underground blasting operations typically involve enclosed spaces and complex interface environments, thus making aerosol pollution from underground blasting projects increasingly risky, concentrated, and complex. Focusing on the identification and control technologies of key hazardous components of aerosols from blasting projects has significant scientific and social value, contributing to overcoming bottlenecks in the development of blasting engineering and related disciplines.

[0004] It is evident that how to solve the problem of the inability of existing small-volume detonation devices to continuously detonate and the research gap in the field of environmental science regarding reactors with three-phase interfaces of explosive pollutants are technical problems that urgently need to be solved by those skilled in the art.

Then close the lid of the vessel.

[0015] Open the valve system of the air intake and exhaust pipes to gradually expel the air from the blast space, so that the blast space reaches a vacuum state;

[0016] Once the blasting space reaches a vacuum state, the pressure sensor and temperature sensor are activated, and the valve system is closed.

[0046] Example 1:

[0047] like Figure 1As shown, this embodiment provides a civilian continuously detonating explosive container, which includes: a reaction vessel 10, which includes a vessel body and a vessel cover, the vessel body and the vessel cover being detachably and sealed together; the vessel body and the vessel cover together form an explosion space; a plurality of strong magnetic injectors, each of which includes a strong magnetic switch 1 and an explosion-proof cover 6, the tops of the plurality of strong magnetic switches 1 being evenly and fixed around the vessel cover, and the explosion-proof cover 6 being correspondingly and tightly fixed to the bottom of the strong magnetic switches 1, located within the explosion space; and an ignition device 4, which includes a plurality of electronic detonators adapted to the number of strong magnetic injectors, the plurality of electronic detonators being connected in series to form the ignition device 4; wherein, the plurality of electronic detonators are respectively inserted into the plurality of strong magnetic switches 1 and the explosion-proof cover 6.

[0048] Specifically, this embodiment provides a civilian continuous detonation explosive container, including: a reaction vessel 10, several strong magnetic samplers, and an ignition device 4; the reaction vessel 10 includes a vessel body and a vessel lid, which are detachably and sealed together; the vessel body and the vessel lid together form a blasting space, through which explosive detonation research is conducted; each of the several strong magnetic samplers includes a strong magnetic switch 1 and an explosion-proof cover 6, which can remotely and precisely control the detonation time; wherein, the explosion-proof cover reduces the pressure and temperature conduction efficiency during continuous detonation, and the strong magnetic switch controls the detonation time and the number of detonations. The detonation switch of the explosive is precisely controlled by the setting of the ignition device 4. As an achievable method, the explosion-proof cover 6 corresponding to the strong magnetic switch 1 will only detonate when the ignition device 4 and a certain strong magnetic switch 1 are simultaneously in the open and closed states, respectively. By controlling the detonation time and the number of detonations by setting the strong magnetic switch, multiple explosives in the existing small-volume detonation device can be detonated flexibly and continuously (they can be detonated simultaneously or sequentially). Since the effect of continuous explosion of small yield can be equivalent to a single explosion of large yield, the technical effect of conducting large yield explosion experiments in a small-pressure detonation container device can be achieved.

[0049] In some possible implementations, the civilian continuous detonation explosive canister also includes an inlet pipe 5 and an exhaust pipe 9, the tops of which are inserted into the canister cover and connected to a valve system; the detection ends of the inlet pipe 5 and the exhaust pipe 9 pass through the canister cover and are located within the blasting space.

[0050] Specifically, the civilian continuous detonation explosive container is also equipped with an air inlet pipe 5 and an exhaust pipe 9. The air inlet pipe 5, the exhaust pipe 9 and the valve system work together to control the entry and exit of gas in the reactor. When in use, air can be discharged to make the explosion space a vacuum state. After the explosion is completed, air can also be introduced into the explosion space to make the explosive, pure water and air three phases fully mixed, which is convenient for reaction research.

[0051] In some possible implementations, the explosive canister for continuous detonation in civilian applications also includes a pressure sensor 2 and a temperature sensor 3. The connection ends of the pressure sensor 2 and the temperature sensor 3 are fixedly mounted on the canister lid, and the detection ends of the pressure sensor 2 and the temperature sensor 3 pass through the canister lid and are located within the blasting space.

[0052] Specifically, by setting up pressure sensor 2 and temperature sensor 3, pressure and temperature data during blasting can be monitored, facilitating real-time detection and analysis of relevant data during the blasting process.

[0053] In some possible implementations, the electronic detonator includes a lead wire, a detonator, and a bayonet plug. Several electronic detonators are connected in series via the lead wire. The detonator passes through the strong magnetic switch 1 and is inserted into the explosion-proof cover 6, and is fixed to the explosion-proof cover 6 by the bayonet plug.

[0054] Specifically, the electronic detonator uses an electronic detonator module, which includes lead wire, detonator and bayonet plug, and is connected in series through lead wire to form the entire ignition device, thereby remotely and precisely controlling the detonation switch of the explosive.

[0055] In some possible implementations, the civilian continuous detonation explosive canister also includes a spray pipe 7, which is inserted into the canister lid. The input end of the spray pipe 7 is connected to the spray system, and the output end of the spray pipe 7 is located within the blasting space.

[0056] Specifically, water mist is sprayed into the blasting space through the spray pipe 7 to simulate a blasting dust removal device.

[0057] In some possible implementations, the civilian continuous detonation explosive canister also includes a gas sampling port 8, which is located on the canister lid.

[0058] Specifically, the gas sampling port 8 allows for the rapid extraction of gas from the reactor 10, facilitating environmental science research on the reaction at the three-phase interface of explosive pollutants.

[0059] In some possible implementations, several explosion-proof covers 6 are made of strong magnetic protective covers; and / or, pressure sensor 2 and temperature sensor 3 are made of stainless steel housings; and / or, air intake pipe 5 and exhaust pipe 9 are made of stainless steel alloy casting.

[0060] Specifically, several explosion-proof covers 6 are all highly magnetized strong magnetic protective covers, which can withstand the high temperature and high pressure generated by the explosion. The strong magnetic switch 1 is a highly magnetized electromagnetic switch, which can be magnetically fixed to the explosion-proof cover 6. The pressure sensor 2 and the temperature sensor 3 are both made of stainless steel shells, which can withstand the high temperature and high pressure of the explosion. The air inlet pipe 5 and the exhaust pipe 9 are made of stainless steel alloy casting. The body and lid of the reaction vessel 10 are made of stainless steel to withstand the explosion pressure of 10.1 MPa.

[0061] Example 2:

[0062] This invention provides a method for the blasting of a civilian continuously detonating explosive container, based on the civilian continuously detonating explosive container as described in the embodiment. The blasting method includes the following steps: opening the lid of the reaction vessel, sequentially loading explosives into several explosion-proof covers; turning on the strong magnetic switch, making the explosion-proof cover tightly fit the bottom of the strong magnetic switch, inserting several electronic detonators into several strong magnetic switches and explosion-proof covers respectively, and connecting the several electronic detonators in series to form an ignition device, and closing the lid;

[0063] Open the valve system of the air intake and exhaust pipes to gradually expel the air from the blast space, so that the blast space reaches a vacuum state;

[0064] Once the blasting space reaches a vacuum state, activate the pressure and temperature sensors and close the valve system.

[0065] The explosives are detonated sequentially until all explosives have been detonated.

[0066] Open the spray pipe and spray a certain amount of purified water into the blasting space; open the valve system and introduce air into the blasting space; so that the explosive, purified water and air are fully mixed after the blast.

[0067] Gas is extracted from the blast space through a gas sampling port.

[0068] Specifically, Embodiment 2 of the present invention proposes a method for the use of a civilian continuously detonating explosive canister, which is used to operate the method for the use of the civilian continuously detonating explosive canister provided in Embodiment 1. In use, the explosives are first loaded sequentially into several explosion-proof covers, and the explosion-proof covers are magnetically and tightly fixed to the bottom of the strong magnetic switches using strong magnetic switches. Simultaneously, several electronic detonators are respectively connected to several strong magnetic switches and explosion-proof covers, and these electronic detonators are connected in series to form an ignition device. The canister lid is then sealed onto the canister body. Next, the valve system of the air inlet and exhaust pipes is opened to achieve a vacuum state in the blasting space. The vacuum degree in the blasting space can be changed by adjusting parameters, and numerical simulation studies of the blasting process characteristics are conducted under different vacuum degrees. After the blasting space reaches a vacuum state... The valve system is closed, and the pressure and temperature sensors are activated to monitor the pressure and temperature changes in the blasting space in real time. Explosives are then detonated sequentially until all explosives have detonated. Finally, a spray pipe is opened to spray a certain amount of purified water into the blasting space, simulating a dust removal device. The valve system is then opened to introduce air into the blasting space, ensuring thorough mixing of the explosives, purified water, and air. Gas is extracted from the blasting space through a gas sampling port to study post-blast pollutants. This research aims to study the three-phase interface of blasting pollutants in environmental science, and to demonstrate the technical effectiveness of existing small-volume detonation devices for flexible and continuous detonation of multiple explosives and high-yield explosion experiments in low-pressure detonation containers.

[0069] In some possible implementations, the steps of sequentially detonating explosives until all explosives have been detonated include: turning off a strong magnetic switch, causing its corresponding explosion-proof cover to detach and suspend in the explosion space, turning on the ignition device, and detonating the explosives in the corresponding explosion-proof cover;

[0070] The pressure and temperature inside the blasting space are collected by pressure and temperature sensors to determine whether the pressure and temperature inside the blasting space have decreased to a preset range.

[0071] When the pressure and temperature within the blasting space are within the preset range, repeat the above steps until all explosives are detonated in sequence.

[0072] Regarding the sequential detonation of explosives until all explosives have been detonated, this second embodiment proposes another implementation method. When detonating an explosive, the strong magnetic switch corresponding to that explosive should first be turned off, and the magnetic connection between the strong magnetic switch and the explosion-proof cover used to hold the explosive should be released, causing the explosion-proof cover to detach and be suspended in the blast space through the connection of the electronic detonator, in a ready-to-detonate state. In addition, before each explosive is detonated, it should be determined whether the pressure and temperature in the current blast space have dropped to a preset range. The continuous detonation experiment should only continue when the pressure and temperature in the blast space are within the preset range, thereby controlling the environment in the blast space and creating a stable and sustainable blasting environment.

[0073] In some possible implementations, the steps of connecting several electronic detonators to several strong magnetic switches and explosion-proof covers respectively, and connecting several electronic detonators in series to form an ignition device include:

[0074] The detonator in each electronic detonator is inserted into the explosion-proof cover through the corresponding strong magnetic switch and comes into contact with the explosive, and is fixed to the explosion-proof cover by the bayonet plug in the electronic detonator.

[0075] The leads of several electronic detonators are connected in series to form an ignition device.

[0076] Regarding the steps of connecting several electronic detonators to several strong magnetic switches and explosion-proof covers respectively, and connecting several electronic detonators in series to form an ignition device, this embodiment two proposes another implementation method. The electronic detonator adopts an electronic detonator module, including lead wire, detonator and bayonet plug, and is connected in series through lead wire to form the entire ignition device, thereby remotely and accurately controlling the detonation switch of the explosive. As an achievable method, the explosion-proof cover 6 corresponding to the strong magnetic switch 1 will only detonate when the ignition device 4 and a certain strong magnetic switch 1 are simultaneously in the open state and the closed state respectively. By setting the strong magnetic switch to control the detonation time and the number of detonations, multiple explosives in the existing small-volume detonation device can be flexibly and continuously detonated.
