Cracking device for filling hole with carbon dioxide at one time and method for mounting cracking device in drill hole

Abstract

The embodiment of the invention provides a cracking device capable of filling a hole with carbon dioxide at one time and a method for mounting the cracking device in the drill hole, and relates to the technical field of blasting apparatuses. The carbon dioxide cracking device comprises a pipe body, a heating rod, a filling head, a one-way air inlet valve and an external air pipe, an energy release opening is formed in the pipe body, and the filling head is connected to the open end of the pipe body; the filling head is provided with a filling channel used for filling the interior of the main pipe with carbon dioxide, the one-way air inlet valve used for opening and closing the filling channel is arranged in the filling channel, the one-way air inlet valve is provided with an air inlet and an air outlet, and the external air pipe is connected to the air inlet of the one-way air inlet valve; and the air outlet communicates with the interior of the pipe body. When the cracking device is mounted in the drill hole, the interior of the pipe body of the cracking device can be filled with liquid carbon dioxide through the external air pipe, and compared with the prior art that carbon dioxide needs to be filled outside the hole in advance, the use safety of the carbon dioxide cracking device is improved conveniently.

Description

technical field [0001] The invention relates to the technical field of blasting equipment, in particular to a method for filling a carbon dioxide cracker in a disposable hole and installing it in a drill hole. Background technique [0002] The carbon dioxide cracker is a new type of blasting equipment that uses liquid carbon dioxide to instantly increase the gasification pressure of phase change in a limited space, break through the constant pressure shear sheet, form high-pressure high-energy gas, and achieve a directional blasting effect. The blasting is a process of physical transformation. There is no open flame or electric arc during the blasting process. It is widely used in various industries in China due to its advantages of high blasting power, no need for gun inspection, and simple operation. [0003] However, due to structural limitations, the traditional carbon dioxide cracker needs to be filled with liquid carbon dioxide outside the hole, and then the cracker is...

Problems solved by technology

[0003] However, due to structural limitations, the traditional carbon dioxide cracker needs to be filled with liquid carbon dioxide outside the hole, and then the cracker is sent into the drill hole; The cracker is always under pressure. Sometimes, due to changes in the external environment temperature, the internal pressure of the cracker may increase, and air leakage may occur. At the same time, the cracker may self-explode, causing injury accidents and posing safety hazards.
