The invention relates to a temperature and pressure control system and control method for dry ice cracking devices, and belongs to the technical field of engineering blasting. The temperature and pressure control system comprises a portable moving power source, a dry ice cracking cylinder with an air pipe, a pressure sensing system, a circuit control system and an indicating system. The dry ice cracking cylinder comprises a cracking cylinder body and a cracking cylinder end portion. The cracking cylinder end portion comprises a U-shaped screwing sealing screw block, the air pipe and a plasticgasket. The plastic gasket, the air pipe and a nut form an air pipe connecting system. A pressure sensor is arranged on the extended air pipe. A heating bar, heating powder and an exciter are arrangedin the dry ice cracking cylinder. According to the system, precise control over pre-cracking and detonating of all the dry ice cracking devices can be achieved, the delay detonating function is achieved, and operation safety, reliability, efficiency and the rock breaking effect are improved fundamentally.
Description
technical field [0001] The invention relates to a temperature and pressure control system and a control method of a dry ice cracker, belonging to the technical field of engineering blasting. Background technique [0002] Dry ice cracking tube blasting is a new type of blasting method. First, the dry ice is heated and melted to a liquid state through the heating rod system, and then the rapid heating of the internal chemical causes CO 2 The phase transition makes CO 2 The volume of the pipe increases sharply and breaks through the steel pipe to cause an explosion, achieving the purpose of blasting. [0003] The heating agent in the dry ice cracking cylinder will not cause an explosion, and there is no safety hazard in the process of production and transportation. However, during the process of heating the dry ice with the heating rod system, there will be excessive heating that will cause the iron pipe to burst and insufficient heating to cause the cracking effect to be inef...
