Description

Technical Field

[0002] Emulsion explosives are new water-containing explosives developed in the 1960s and 1970s. They have excellent explosion, safety and water resistance and have been widely used in engineering blasting. When producing emulsion explosives, workers need to mix powdered raw materials and react them with liquid solvents in a reactor to produce explosives. In this process, accurate control of the amount of powdered raw materials is crucial to the production quality of emulsion explosives. At present, when producing emulsion explosives, a scale is usually used to weigh the powdered raw materials, and then the powdered raw materials are fed into the mixing equipment by manual feeding. In this process, since the scale is not a special metering device, it is not possible to accurately weigh the powdered raw materials when using it, resulting in too much or too little powdered raw materials being fed, resulting in large errors, which further affects the production quality of emulsion explosives. In addition, manual feeding is not only labor-intensive, but also time-consuming and labor-intensive, and has low production efficiency.

[0003] Therefore, it is particularly important to design an automatic and quantitative feeding device for the production of powdered emulsion explosives. Utility Model Content
