Description

Technical Field

[0001] The utility model belongs to the technical field of emulsification equipment, and in particular relates to a pesticide microemulsion configuration device. Background Art

[0002] Pesticide emulsion in water is a commonly used pesticide formulation. It is a water-insoluble solution obtained by dissolving a water-insoluble liquid API in an organic solvent, or by dissolving a solid API in an organic solvent after being crushed. The solution is dispersed in water to form an environmentally friendly pesticide formulation, which has an opaque white emulsion appearance and is an oil-in-water (O / W) emulsion.

[0003] Pesticide emulsifier is a device that converts raw materials into finished drugs. The existing pesticide emulsifier is to set a high-speed rotating shear head in the reactor to break up the raw materials and then dissolve them in the solvent. During the use of the existing pesticide emulsifier, the drug blocks cannot be effectively broken up, and the drug liquid is not mixed evenly, which affects the effectiveness and stability of the drug liquid. The high-speed rotation causes shaking, which affects the stability of the reactor. The traditional process equipment has a long oil-water emulsification time and low efficiency, and it is urgent to design a pesticide emulsification device. Utility Model Content
