Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical preparation technology in waterworks, and in particular to an intelligent chemical preparation and intelligent stirring system. Background Technology
[0002] The process of preparing pesticides is applied in various technical fields. In agriculture and forestry, pesticide concentrations need to be precisely controlled; in medicine, especially traditional Chinese medicine, the concentration of herbal decoctions needs to be precisely controlled; and in industrial production, various pharmaceutical preparations also need to be prepared during the production process. However, current pesticide preparation processes rely primarily on human experience and are done manually. Clearly, this complete dependence on manual preparation not only results in inaccurate concentrations and a fixed, unchanging ratio of pesticides, but also leads to variations in pesticide concentration over time during use.
