Carbon dioxide crackers and remote detonation carbon dioxide crackers

Abstract

The invention provides a carbon dioxide fracturer and a remote detonation carbon dioxide fracturer and relates to the technical field of blasting devices. The carbon dioxide fracturer comprises a tank body, an end cover, an activator and a seal member; the activator is connected to the end cover, the tank body is hermetically connected to the end cover, the tank body is provided with a pouring port, the end cover is provided with a pouring passage, the pouring port is communicated with the pouring passage, the pouring passage is hermetically connected to the seal member, and the tank body and the end cover are made of plastic; the technical problem that the prior structure is complex, high in mass and high in cost and has potential safety hazards is solved, better sealing is provided for the tank body, and the tank body is lighter and more environment-friendly, lower in cost. The remote detonation carbon dioxide fracturer comprises a remote detonation carbon dioxide fracturer, a remote detonation receiver and a remote detonator; remote detonation is achieved within a wider range, and in the case of simultaneous detonating of multiple carbon dioxide fracturers, safety of detonation staff is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of blasting devices, in particular to a carbon dioxide cracker and a remote detonation carbon dioxide cracker. Background technique [0002] The traditional method of coal mining is explosive blasting. Explosive blasting is powerful and powerful, and it is a typical open flame blasting. However, open flame blasting has many defects, and it has high requirements for use conditions, use environment, daily wear management, etc., especially when blasting in high-gas mines, it is very likely to cause explosions of gas and coal dust, bringing safety to coal mines Hidden danger. [0003] Due to the unsafety of explosive blasting, carbon dioxide detonation technology began to rise. This technology has been valued and developed as early as the 1950s, and it was specially developed for the coal mining face of high-gas mines. At present, carbon dioxide detonation technology has been extended to the rapid and safe bla...

AI Technical Summary

Problems solved by technology

[0004] However, the repeated use of cracking tubes in the prior art requires more than three people to operate when the single weight of the cracking tube reaches more than 30 kg. There are too many parts, the disassembly and assembly are too cumbersome, and it needs to be recycled and disassembled after use.

In addition, the existing disposable carbon dioxide cracking tube is made of iron, which is also of high quality and high cost, and the process is cumbersome. If the process is not high, leakage will occur. Too many iron sealing rings are easy to leak, which is not good for landfill. It will cause the flight tube to easily cause safety hazards, etc.
