Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, in particular to a carbon dioxide phase-change expansion excitation tube charging machine. Background Art

[0002] Carbon dioxide phase change expansion technology is a rock breaking method based on physical explosion. This technology mainly uses carbon dioxide to exist mainly as liquid carbon dioxide molecules when the pressure is higher than 7.38MPa and the temperature is lower than 31.1℃. When electricity is turned on to trigger the carbon dioxide phase change expansion excitation tube (also called activator, heater, etc.) to produce chemical reaction and heat release, making the ambient temperature instantly higher than 31.1℃, the liquid carbon dioxide in the fracturing tube will undergo phase change to generate high pressure and break the rock. This technology has the advantages of no sparks, low vibration, low noise, and less flying rocks during the blasting process. It has outstanding advantages in the field of engineering blasting under complex environments and has been widely used at home and abroad in recent years.

[0003] The carbon dioxide phase change expansion excitation tube is the core component of this technology. The excitation tube mainly uses powdered agents such as potassium perchlorate, ammonium oxalate, salicylic acid, etc. as the main raw materials. The excitation tube needs to be formed into a finished product by mixing the agents evenly and filling them into an excitation tube shell with an electric ignition head.

[0004] Since the excitation tube is equipped with an electric ignition powder head that runs through the entire tube shell, the commonly used powder loading methods such as spiral pressing or cylinder-pushing punch pressing are easy to damage the electric ignition powder head in the excitation tube, so it is difficult to achieve mechanized charging. At present, the excitation tube is mainly loaded manually by placing a funnel on the excitation tube shell, pouring the weighed medicine into the funnel, and knocking the excitation tube shell back and forth to achieve quantitative charging of the excitation tube. This manual charging method mainly has the following problems: first, the degree of mechanization is low, and a single person can only charge a single excitation tube at a time, which is inefficient and the labor intensity of the workers is high; second, a large amount of dust and noise are generated during the knocking process, which is not conducive to the physical and mental health of the workers, and there is a risk of dust explosion.
