Abstract

The invention relates to the field of carbon dioxide blasting, and particularly discloses a carbon dioxide fracturing device. The carbon dioxide fracturing device comprises a pipe body, a heating device arranged in the pipe body, a first connecting end arranged at the top end of the pipe body and a second connecting end arranged at the bottom end of the pipe body, wherein a cavity communicating with the first connecting end and the second connecting end is formed in the pipe body, a supporting piece is arranged at the top end of the pipe body, a thermal expansion material is arranged on the supporting piece, a sealing piece is arranged at the top end of the thermal expansion material, and the second connecting end communicates with a liquid carbon dioxide filling device. According to the carbon dioxide fracturing device, the cavity is filled with liquid carbon dioxide, and after the liquid carbon dioxide fills upwards from the bottom end of the cavity and is close to the first connecting end, and the thermal expansion material can be shrunk, so that the sealing piece blocks one end of the first connecting end, the filling process is simplified, air in the cavity is remarkably reduced, and the filling quality is improved.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide blasting, in particular to a carbon dioxide cracker. Background technique [0002] The carbon dioxide cracker uses liquid carbon dioxide to be heated and gasified to expand, and quickly releases high-pressure gas to break rocks or drop coal, which overcomes the previous characteristics of explosive mining, pre-splitting, high destructiveness and high-risk ore body crushing. Different from traditional products, carbon dioxide crackers do not produce open flames, heat sources and various toxic and harmful gases produced by chemical reactions, and can be recycled and reused. Specifically, the carbon dioxide cracker includes a tube body for filling liquid carbon dioxide, a filling valve arranged at one end of the tube body, an energy discharge valve, a constant pressure shearing piece, a heating device and an exciter. Before using the carbon dioxide cracker, it is necessary to fill the tube bo...
