Problems solved by technology

[0002] With the rising level of national economic development, the demand for industrial production is also increasing. The western regions of my country, such as Tibet and Xinjiang, are rich in various resources. Therefore, it is necessary to build railways and develop minerals in these high-altitude areas to promote The economic development of the western region has also brought convenience to the lives of local people. Many of these projects require blasting operations. The low population density of the local area is also suitable for the development of blasting operations. However, the high altitude of these areas leads to atmospheric pressure and environmental pollution. The temperature is relatively low, so there are new requirements for the selection of blasting equipment and the adjustment of blasting technology. For now, there are few studies on explosion experiments in low-temperature and low-pressure environments. The use of explosion containers that create a low-temperature negative pressure environment can be effective. The simulated blasting operation under plateau conditions has important reference and practical value for the study of explosive performance and other parameters in plateau environment and the selection of blasting equipment, and has a high guiding significance for the damage performance test of ammunition in high-altitude low-temperature and low-pressure environment

Embodiment 1

[0044] An explosion container for creating a low-temperature negative pressure environment, comprising the following steps:

[0045] Step 1: Open the entrance 1 of the explosion container, turn on the smoke exhaust fan 11 above the tank, fully circulate the internal air and the outside world, and then turn off the smoke exhaust fan;

[0046] Step 2: The operator enters the interior of the explosion container, places the explosives, the detonator and other devices, and connects the detonator to the internal detonating wire B8 and the internal detonating wire A7 after short-circuiting the external wires;

[0047] Step 3: Connect the line of the detonation velocity meter to the interface of the equipment and the thermometer. After testing the normal operation of the detonation velocity instrument, tighten the knob and seal the interface with vacuum mud;

[0048] Step 4: After confirming that it is correct, the operator leaves the explosion vessel and closes the entrance to ensure...

Embodiment 2

[0056] The operation steps of an explosion container for creating a low-temperature negative-pressure environment are roughly the same as those in Example 1, except that in Example 2, the detonation wave curve of the explosive is tested in a low-temperature negative-pressure environment, and the connected instruments are replaced with sensors and oscilloscopes.

[0057] Step 1: Open the entrance of the explosion container, turn on the smoke exhaust fan 11 above the tank, fully circulate the internal air and the outside world, and then close the smoke exhaust fan.

[0058] Step 2: The operator enters the inside of the explosion container, places the explosives, the detonator and other devices, and connects the detonator to the internal detonating wire B8 and the internal detonating wire A7 after short-circuiting the external wires.

[0059] Step 3: Connect the sensor to the interface of the equipment line and the thermometer, and connect the sensor to the oscilloscope to test wh...

Embodiment 3

[0068] The operation steps of an explosion container for creating a low-temperature negative-pressure environment are roughly the same as those in Example 1, except that Example 3 tests the explosiveness of explosives in a low-temperature negative-pressure environment without connecting an instrument.

[0069] Step 1: Open the entrance of the explosion container, turn on the smoke exhaust fan 11 above the tank, fully circulate the internal air and the outside world, and then turn off the smoke exhaust fan;

[0070] Step 2: The operator enters the interior of the explosion container, and places the explosives, detonator, test lead post and other devices in place, and connects the detonator with the internal detonating wire B8 and the internal detonating wire A7 after short-circuiting the external wires;

[0071] Step 3: After confirming that it is correct, the operator leaves the explosion vessel and closes the entrance to ensure that the airtightness of the explosion vessel mee...

Abstract

The invention discloses an explosion container for creating a low-temperature negative-pressure environment, and belongs to the technical field of explosion containers. The explosion container comprises a tank body, a water-cooled vacuum pump mounted on one side of the tank body, a liquid cooling machine mounted on the other side of the tank body and a smoke exhaust fan mounted on the top of the tank body, wherein a cooling water tower is mounted on the other side of the liquid cooling machine, a vacuum pump operation box is arranged on one side of the water-cooled vacuum pump, the tank wall of the tank body is sequentially provided with a tank body inner wall, a tank body middle layer and a tank body outer wall from inside to outside, and an anti-explosion vacuum door is arranged on the tank body. According to the invention, a heat conduction mode is adopted for cooling, air exchange with the interior is not needed, and the cooling process and the vacuumizing process can be carried out at the same time, so that the preparation time needed by an experiment is greatly shortened, and experiment errors caused by multiple times of operation are reduced; and variables can be conveniently changed, explosion parameters under different pressures can be conveniently researched, and due to the constant-temperature design, the next experiment can be quickly carried out only by changing the vacuum degree.
