Disposable carbon dioxide cracking device and manufacturing method thereof

Abstract

The invention discloses a disposable carbon dioxide cracking device and a manufacturing method thereof, and belongs to the field of carbon dioxide cracking devices and the manufacturing methods of the carbon dioxide cracking devices. The disposable carbon dioxide cracking device comprises an expansion pipe, an activator, an upper plug and a locking device, wherein the expansion pipe and the upper plug form a closed container, and the activator is located in the closed container; a mounting opening for mounting the activator is formed in the upper plug, and the locking device is used for sealing the mounting opening; a liquid filling hole is formed in the expansion pipe or the upper plug; a locking valve for controlling the on-off of liquid filling is arranged at the liquid filling hole; the expansion pipe mainly comprises a pipe body and a lower end cover, and when the liquid filling hole is formed in the expansion pipe, the liquid filling hole is formed in the lower end cover of the expansion pipe. According to the invention, a cut long groove is formed in the expansion pipe and a constant pressure energy relief sheet is removed to reduce the material consumption; tedious recycling is reduced, and the material cost is low.

Description

technical field [0001] The technology of the invention relates to a carbon dioxide cracker and a manufacturing method thereof, in particular to a disposable carbon dioxide cracker for rock mass blasting and a manufacturing method thereof. Background technique [0002] Carbon dioxide gas explosion technology began to be valued and developed by the United Kingdom in the 1950s. It was originally developed specifically for the coal mining face of high-gas mines. At present, it has been extended to the rapid and safe blasting of rocks, concrete and other substances, and is widely used in the steel and cement industries. Because it only produces low noise and low vibration, it has the advantages of low price, safety, and ease of use compared with explosives. At present, most of them are recyclable and reusable carbon dioxide crackers, the structure of which is: one end of the liquid storage pipe made of high-strength alloy steel is equipped with a constant pressure energy release...

AI Technical Summary

Problems solved by technology

However, there are also the following shortcomings and deficiencies in actual production: because the gas explosion tube is subjected to high pressure during blasting, it is made of molybdenum steel with excellent fatigue resistance after heat treatment, so that the material cost remains high, and the design is to ensure its Intensity and repeated use, the thickness of the pipe arm reaches more than 14mm, resulting in heavy weight and laborious transportation; after blasting, due to rock mass movement and other reasons, the pipe body is tightly pressed, causing bending and broken pipes, making it difficult to recycle. It needs to be used with an excavator at the same time, and the production cost is high; because it is an external wire, three to four people are required to connect the pipe manually on site, which increases the labor cost; The originally safe gas expansion has become unsafe; it is easy to squib, because the terminal post on the nonel tube is easily shorted with the lifting sling, and the defect in the original design of the leaking head leads to non-conduction and gas leakage failures; the original structure There are fatal design flaws, the deflated head is easy to break; every time you fill the tube, you need to wash the tube, wasting carbon dioxide
