Uniform mixing and stirring apparatus of pesticide emulsion containing surfactant

Abstract

The invention discloses a uniform mixing and stirring apparatus of a pesticide emulsion containing a surfactant. A heat exchange coil tube is arranged on the inner wall of a stirring apparatus body, a heat insulation jacket is arranged on the outer wall of the stirring apparatus body, a high-shear emulsifying machine is arranged at the upper end of a gear device, and is in transmission connection with a driving shaft, a gear speed reducer is arranged at the left side of the upper end of the stirring device and is arranged at the left side of the gear device, an outer frame stirrer is arranged in the stirring apparatus body, a stirring shaft is arranged in the middle of the upper end of the outer frame stirrer, the output shaft of the high-shear emulsifying machine is arranged at the inner side of the stirring shaft, a propeller blade is fixedly connected with the output shaft of the high-shear emulsifying machine, and an emulsifying head is arranged at the lower end of the stirring shaft. The uniform mixing and stirring apparatus of the pesticide emulsion containing the surfactant has the advantages of good safety and reliability, production cost reduction, uniformity in stirring, no blind angles, and simplicity in operation.

Description

technical field [0001] The invention relates to the technical field of mixing and stirring, in particular to a mixing and stirring device for pesticide emulsion containing surfactant. Background technique [0002] Emulsification is a liquid-liquid interface phenomenon in which a liquid is uniformly dispersed in another immiscible liquid with tiny droplets. Two immiscible liquids are stirred vigorously after adding appropriate surfactants. This process is called emulsification. Emulsion is the most widely used dosage form in production. From watery fluid to viscous paste, it is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food, etc. field. [0003] The mixing drum of the existing pesticide emulsification reactor is equipped with a stirring device, which generally includes a stirring shaft driven by a motor, and the stirring shaft is arranged at the center of the mixing drum. In the emulsifier with this structure, only the middle stirring shaft is rot...

AI Technical Summary

Problems solved by technology

[0003] The mixing drum of the existing pesticide emulsification reactor is equipped with a stirring device, which generally includes a stirring shaft driven by a motor, and the stirring shaft is arranged at the center of the mixing drum. In the emulsifier with this structure, only the middle stirring shaft is rotating. The mixing effect is poor, the mixing is uneven, the stratification is obvious, the storage time is short, the product is unstable, and the medium near the side wall of the mixing drum cannot be well stirred

At the same time, it does not have an insulation jacket and a heating system, and cannot effectively heat and control the temperature of the reactor in time, and has no monitoring function.
