Problems solved by technology

However, this method only provides a partial vacuum environment, and the process of explosive processing will still be affected by the surrounding air, and the expected explosive effect cannot be fully achieved.
[0005] CN201621118154.1 discloses an explosive welding device for metal composite materials in a vacuum state. Through this device, it is not necessary to go to an open-air explosion field far away from residential areas for explosive processing, and it is only carried out in the mining explosion field of the unit, and will not cause interference to surrounding residents. , but the device does not involve the monitoring and elimination of toxic and harmful gases produced by the explosion
CN201702039295.7 discloses a spherical explosion container, and designs an explosion container that can be photographed by X-rays, but the use of the explosion container is not in a vacuum environment, and at the same time, there is a lack of internal protective measures for the opened window

Embodiment 1

[0034] As a method of processing metal composites, explosive welding has a wide range of application scenarios. However, in the traditional production process, welding quality defects caused by air and noise generated by explosions will have many restrictions on the popularization and application of this technology. The vacuum production environment provided by the device of the invention can overcome the defects of the method.

[0035]Explosive welding main explosives use porous granular ammonium oil explosives or emulsion explosives, mixed with perlite, the general explosive detonation velocity is controlled at about 2200m / s, the double board is 304 board with a thickness of 3mm, the board surface is 500mm×500mm, and the substrate is 6mm thick 304 plate, the plate surface is 450mm×450mm, the end is detonated, according to the attached figure 2 Arrangement, put the explosive welding device into the vacuum device, close the chamber door, pump air through the exhaust port, me...

Embodiment 2

[0037] Due to the existence of a large number of asteroids in space, the reserves of rare metals such as palladium and platinum are quite abundant. Therefore, the establishment of an asteroid base to engage in related mining work is the only way for future development. The device can simulate the ore mining effect in the vacuum environment in space, thereby improving the production process.

[0038] Classification of blastability of rock mass is the basis of optimal design and construction of blasting parameters, so it is very important to study blasting funnels in vacuum environment. A cement concrete block of 1m×1m×1m is poured in the device, and a hole with a diameter of 34mm is arranged in the center. The charge depth is used to study the blastability of rock mass in vacuum environment. After the charge is filled, connect the wires, close the chamber door, draw air through the exhaust port, measure the negative pressure to -0.08MPa, and then detonate. After the explosio...

Abstract

The invention discloses a vacuum explosion effect testing device, which comprises a tank body; the upper end of the tank body is respectively connected to a vacuuming device and a smoke exhausting andgas exchanging device through pipelines; a spray device is arranged at the top of the tank body; a toxic and harmful gas monitoring device is also arranged in the tank body; a wiring sealing window and an observable window are arranged on both sides of the tank body; a double-layer sealing door is arranged at one end of the tank body; a detachable device table and a replaceable cushion are arranged at the bottom of the tank body. Due to the arrangement of a spray dust reduction system, a purification system, and the toxic and harmful gas monitoring device, toxic and harmful substances generated in explosion are monitored, prescribed, removed and absorbed, thereby ensuring the safety of operation personnel performing an explosion effect test in a vacuum environment to the greatest extent.In addition, a damping groove is formed outside the device, and a surface, connected with a base, of the device is filled with a vibration damping material, so that vibration hazards caused by an explosion effect are reduced.

Description

technical field [0001] The invention relates to the technical field of explosive processing, in particular to a vacuum explosion effect test device. Background technique [0002] Explosion refers to a physical and chemical process in which energy is transformed rapidly in a limited volume. Explosion effect refers to that in the process of change, along with the rapid conversion of energy, some form of internal energy of matter is transformed into mechanical compression energy, light, heat radiation, etc. influences. Explosive effects involve explosive processing (explosive synthesis, explosive forming, explosive compounding, explosion strengthening, explosion hardening, etc.), explosion shock wave propagation law, explosion reaction mechanism research, explosion product detection, and monitoring of explosive toxic and harmful gases. The explosive effect of this is of great significance to the development of social productivity. [0003] The existing application of the exp...
