Description

technical field [0001] The invention relates to bulk emulsion explosive production equipment, in particular to a preparation device for latex matrix transporting drag reducer. Background technique [0002] At present, the annual use of bulk emulsion explosives in my country only accounts for 17% of the total, while the use of bulk emulsion explosives in developed countries in Europe and the United States has reached 80%. The shortage of bulk emulsion explosives has been gradually accepted by blasting engineering, and the development of bulk emulsion explosives has also received policy support from the state and the industry, and its market demand is becoming more and more obvious. [0003] Due to the complex terrain of mines in my country and the diversity of mining operating conditions, most mines are dominated by small and medium-diameter blastholes (blasting hole diameters below φ200), and due to terrain reasons, many blastholes at blasting sites, on-site mixed trucks It c...

AI Technical Summary

Problems solved by technology

However, the on-site mixing trucks that have been developed and applied to blasting operations in the Chinese market currently have the following deficiencies when transporting latex substrates: they can only be used for large-diameter blast holes (blast hole diameters above φ200, and delivery pipe diameters above φ50), The latex matrix (within 50 meters) is conveyed for blasting operations in a short distance, and the conveying pressure is above 1.0MPa. The conveying pressure is too high, which poses a safety hazard. Because the resistance is too high during conveying, the conveying pressure is too high, which is easy to cause an explosion accident. As a result, it is impossible to transport small-diameter blastholes and long-distance blastholes. These cannot meet the needs of mine blasting in my country, which seriously restricts the application and development of bulk emulsion explosives. To meet the needs of mine blasting, small tubes for mixed vehicles are required. Long-distance low-pressure transport of latex matrix for blasting operations. To meet this requirement, the key technology to be solved urgently is to develop a device for preparing drag reducing agent. Mix and stir at a certain process temperature, pressure and speed to form a uniform and stable mixed solution of drag reducer

[0004] Deficiencies in existing technical solutions: At present, because there is no drag reducing agent preparation device, the way of lubricating and reducing drag when latex is transported is to use water as drag reducing agent for lubrication. This kind of water is used as drag reducing agent. It is easy to demulsify the matrix in the medium, which seriously affects the blasting performance of the explosive. At the same time, the drag reduction effect is very poor, which makes the delivery pressure too high (the delivery pressure is above 1.0MPa), and explosion accidents are easy to occur during the delivery process, and there are potential safety hazards. Long-distance transportation with small pipe diameters
