Explosion container for creating low-temperature negative-pressure environment

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.

Description

technical field [0001] The invention relates to a blasting container, in particular to an explosion container for creating a low-temperature negative pressure environment, and belongs to the technical field of blasting containers. Background technique [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.

[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
