Embodiment 1

[0021] A carbon dioxide expander designed in this embodiment includes: a tail end cap, a snap ring, an energy release sheet, an energy release hole, an arrow indicating the direction of the energy release hole, a heating tube, a sealing gasket, an expander cylinder, and a filling head , Sealed insulating terminal, liquid storage tank.

[0022] The expander cylinder body 4 is threadedly connected with the tail head 3, the tail head 3 has a connecting ring 2, and the center of the connecting ring 2 has a bolt hole 1. The cover 17 has a sealed and insulated terminal 15 and a terminal 16, the sealed and insulated terminal 15 penetrates the cover 17 and is sealed and insulated therewith, and the terminal 16 is connected to the cover and is electrically connected thereto. The clasp 6 is threadedly connected with the expander cylinder 4 for fixing the energy dissipation sheet 7, and the inner side of the clasp 6 is hexagonal for easy tightening. There are insulating sealing rings 18...

Embodiment 2

[0025] The carbon dioxide expander designed in this embodiment is basically the same as that in Embodiment 1, the difference is that the filling head 13 of the two expansion tubes and the tail end head 3 are connected by bolts through the connecting ring 2, and at the same time, the cylinder body 4 of the two expansion tubes is ensured. The direction of the energy release hole indicates that the arrow 19 is in the same direction. Connect the sealed and insulated terminal 15 on the cover 17 of the last carbon dioxide expander with the sealed and insulated terminal 15 on the filling head 13 of the next carbon dioxide expander with a wire, and connect the cover 17 of the previous expander with a wire The terminal post 16 on the top is connected with the terminal post 16 on the filling head 13 of the next expander to form a passage. Connect the terminal 16 on the cover 17 of the next expander with the sealed and insulated terminal 15 to form a path with wiring, and connect the sea...

Abstract

The invention aims to provide a carbon dioxide expander to overcome the defects of the prior art. Wires on the upper side and lower side of a heating pipe are both longer than the total length of a liquid storage bin, the direction of an energy relief hole can be seen obviously through an energy relief hole direction indication arrow after the expander is embedded, energy relief holes of different expansion pipes can still be made in the same direction through the energy relief hole direction indication arrow when multiple expanders are connected in series, and the multiple expanders connected in series can be put down or lifted at the same time. The carbon dioxide expander not only can be used vertically, but also can be used horizontally or in other directions, it can be ensured that explosion of energy relief holes can be conducted in a predetermined direction for a single expander or when multiple expanders are connected in series, and the multiple expanders connected in series can be put down or lifted conveniently at the same time. Therefore, the carbon dioxide expander has better adaptability, better directionality, higher using efficiency and the like.

Description

technical field [0001] The invention relates to a blasting device, in particular to an expander using carbon dioxide as a detonating material, and belongs to the technical field of blasting. Background technique [0002] China is a country rich in various mineral reserves and complex topography. With the rapid development in recent years, the demand for ore mining, terrain modification and demolition of dilapidated houses has further increased. And existing blasting technology is based on explosive blasting. Explosives are powerful and have a short action time, which belongs to open flame blasting. However, open flame blasting has defects such as high noise and easy fire hazards, and has relatively high requirements for storage conditions, transportation conditions, and use conditions. [0003] Carbon dioxide blasting is a physical blasting that uses liquid carbon dioxide to rapidly gasify when heated and impact the outside world. Carbon dioxide blasting will not produce...
