Description

Technical Field

[0001] The utility model belongs to the technical field of water suspension production, and specifically relates to a mixing device for water suspension production. Background Art

[0002] Pesticide aqueous suspension refers to a multiphase dispersion system formed by dispersing water-insoluble solid raw materials in water by certain mechanical means. The appearance of the aqueous suspension is an opaque suspension, and the particle size of the dispersed phase is generally 0.5-5μm, and the average particle size is 2-3μm. The aqueous suspension belongs to a multiphase coarse dispersion system. Any pesticide that can be stable in water for a long time without decomposition, insoluble in water or slightly soluble in water can be made into an aqueous suspension. Compared with traditional formulations, pesticide aqueous suspensions have the following advantages: no dust hazard; water is used as the dispersion medium, and there is no flammability and pesticide damage caused by organic solvents; high specific gravity and small packaging volume; the suspension has good dispersibility and adhesion, high suspension rate, strong ability to adhere to the surface of plants, and resistance to rain erosion, so the efficacy is more significant and more lasting than wettable powders; it has small particles, large active surface, strong permeability, low cost and high efficacy. Therefore, compared with other pesticide formulations, aqueous suspensions are safe and environmentally friendly, and have become a pesticide variety with a larger tonnage among new water-based pesticide formulations.

[0003] During the production and mixing process of water suspension, the position of the stirring mechanism inside the traditional mixing device is relatively fixed, which limits the stirring range and affects the stirring quality. It is easy to cause the granular medicine to settle at the bottom. In addition, the viscosity of the water suspension is relatively high, and some of it is easy to adhere to the inner wall of the mixing tank, which makes the water suspension not stirred and mixed sufficiently, affecting the quality of the finished product. For this reason, we propose a mixing device for the production of water suspension. Utility Model Content
