Problems solved by technology
[0004] The above-mentioned first sensitization method has the following disadvantages: the mixing of the latex matrix and the sensitizer in the mixer causes a part of the matrix to foam to form an explosive, which has a certain sensitivity. The mixer is a forced stirring device. When objects such as metal impurities enter the mixing After the device, there is a possibility of danger due to heat accumulation due to friction; the medium pumped by the screw pump to the drug delivery hose is already an emulsion explosive. From the structural principle of the screw pump and the long-term use experience of the screw pump in the civil explosive industry, it can be known that the pump There are great potential safety hazards in the delivery process; currently most of the screw pumps used in mixed trucks are imported from abroad, and their cost is relatively high. Two screw pumps are needed to complete the delivery of latex matrix and sensitized emulsion explosives
But its disadvantages are: the inside of the static mixer is easy to block; the sensitization effect is not good; the drug delivery efficiency is low; the sensitized emulsion explosive enters the blast hole in a jet state, and the excessive flow rate will cause the emulsion explosive must destroy

Description
technical field [0001] The invention relates to a mixing device, in particular to a sensitization device for emulsion explosive mixing vehicles. Background technique [0002] At present, there are two main ways of sensitizing the latex matrix in the domestic emulsion explosive mixing vehicle technology. One is to transport the latex matrix and sensitizer to a sensitizing device on the mixing vehicle for mixing and stirring. The slurry is transported to the drug delivery hose with a screw pump and loaded into the blast hole; the other is to use the sensitizer as a drag-reducing lubricant for the drug delivery hose, and use a screw pump to pump the latex matrix into the drug delivery hose. A static mixer is arranged at the end of the hose, and the latex matrix and the sensitizer are mixed at the end of the delivery hose, that is, at the bottom of the blasthole, by the static mixer, thereby completing the latex matrix sensitization process. [0003] The above-mentioned first s...
