Gas exhaust valve type carbon dioxide cracking tube and parallel cracking device thereof

Abstract

The invention discloses a gas exhaust valve type carbon dioxide cracking tube and a parallel cracking device thereof. The gas exhaust valve type carbon dioxide cracking tube comprises gas exhaust typecracking tubes, a gas parallel device, an exploder and an electronic fuse wire. The parallel cracking device can be used for detonating while connecting multiple gas exhaust type cracking tubes in parallel, and improves blasting power of single gas exhaust type cracking tube better; while an electronic fuse is accessed to a power supply, a heating tube quickly acts for enabling carbon dioxide inthe outer tube to instantly gasify and expand, so that pressure in the tube is quickly increased, the outer tube is expanded to be broken, the whole detonation process is very quick, and production efficiency is high; and the gas exhaust valve type carbon dioxide cracking tube achieves once pulverizing, and is great in detonation power.

Description

Technical field: [0001] The invention relates to the technical field of blasting devices, in particular to an exhaust valve type carbon dioxide cracking tube and a parallel cracking device thereof. Background technique: [0002] In the existing blasting technology, most of the blasting tubes are used to replace the traditional explosives during the blasting operation. The existing carbon dioxide blasting device, such as the carbon dioxide blasting device in the invention patent with application number 201520141713.X, has a top end of the blasting tube. A filling head with a filling hole. The filling head is provided with a valve core matching the filling hole and a terminal post matching the detonating device. The terminal post covered with an insulating tube is connected to the terminal screw. The tail of the blasting tube There is a venting head with a blasting hole and a decompression hole at the end, a bursting disc is set between the venting head and the blasting tube, ...

[0002] In the existing blasting technology, most of the blasting tubes are used to replace the traditional explosives during the blasting operation. The existing carbon dioxide blasting device, such as the carbon dioxide blasting device in the invention patent with application number 201520141713.X, has a top end of the blasting tube. A filling head with a filling hole. The filling head is provided with a valve core matching the filling hole and a terminal post matching the detonating device. The terminal post covered with an insulating tube is connected to the terminal screw. The tail of the blasting tube There is a venting head with a blasting hole and a decompression hole at the end, a bursting disc is set between the venting head and the blasting tube, the first wire passing through the venting head, the blasting tube, and the filling head and the first wire connected to the shell of the blasting tube The two wires are respectively connected to the power supply and can be used repeatedly, but the directional blasting force is small, and it is difficult to meet the blasting requirements for large-scale external operations. If there is too much moisture, the cracking tube will not be fully inflated during the inflation process, resulting in a decrease in blasting power; moreover, the current carbon dioxide blasting tubes generally use a carbon dioxide cracking tube to independently blast the power is relatively small
