Description

Technical Field

[0001] This utility model relates to the field of solution preparation technology, and in particular to a solid reagent addition device. Background Technology

[0002] Coal dust is generated during tunneling or mining, severely polluting the underground working environment. Conducting coal dust control experiments and controlling dust concentration at the working face are of great significance for improving the working environment and protecting the health of workers. Spray dust suppression technology is one of the most economical and efficient dust suppression technologies and is widely used in mine dust control. Adding surfactants to water and spraying them can improve dust control efficiency. However, the most effective surfactants currently available are all solid reagents. Therefore, it is particularly important to develop a continuous preparation technology for solutions made from solid dust suppression reagents.

[0003] Currently, there are two main methods for adding surfactants or other liquids. One method is to prepare a surfactant solution of a certain concentration in a solution tank, mix it evenly, and then use it directly for spraying or water injection. The disadvantage of this method is that it requires the preparation of surfactant solutions of different concentrations, which requires a large amount of work. Moreover, the supply of surfactant solution will be intermittent during the preparation process, and the supply process cannot be continuous. The second method is to pressurize the solution with an injection pump and inject the reagent into the water supply pipeline to achieve a continuous supply of dust-suppressing reagent. However, this method is not suitable for solid reagents. Utility Model Content
