The present invention belongs to the technical field of pesticide preparation quality management, and specifically discloses a pesticide preparation quality consistency management and evaluation method based on visualization. When performing appearance image acquisition on batch-produced pesticide preparations, the present invention first uses standard appearance colors to select background colors for image shooting, and performs image quality scoring after the appearance image acquisition, and then performs targeted image acquisition adjustment according to the scoring results, thereby realizing dynamic acquisition of appearance images of batch pesticide preparations, and being able to maximize the consistency of appearance image quality. Subsequently, when performing physical and chemical performance quality tests on batch pesticide preparations, test consistency evaluation is performed based on test results and test result stability time, and retesting is performed when the evaluation does not meet the standards, thereby ensuring that quality analysis results are obtained under stable and consistent conditions, and invisibly improving the accuracy and reliability of the analysis results.

This utility model relates to the field of lithium-ion battery powder manufacturing technology, and discloses a protective system to avoid material contamination in the filling silo. The system includes: a discharge pipe, one end of which is connected to an external silo via a first valve, and the other end of which is equipped with a second valve; the discharge end of the second valve is equipped with a flexible connection for connecting to the inlet of a high-speed mixer; the first valve is positioned higher than the second valve; and an observation component, installed on and connected to the discharge pipe, for observing whether material has fallen into the second valve. This system addresses the problem that when material is discharged from the silo, it easily accumulates at the discharge valve at the bottom of the silo, making it difficult to completely close. During mixing, material leakage from the discharge valve leads to inaccurate proportions and affects product quality.
