Wettable powder mixer

Abstract

The invention discloses a wettable powder mixer which comprises a mixer base and a U-shaped mixing tank arranged on the base, wherein the mixing tank comprises a feeding hole formed in the top and a stirring shaft arranged insides; the mixing tank is connected onto the base through the stirring shaft; a sealing cover is arranged at the feeding hole; a hollow pipe is arranged in the stirring shaft;the hollow pipe is filled with cooling liquid; the stirring shaft is connected with a motor; stirring paddles are arranged on the stirring shaft; and the outer walls of the stirring paddles are connected with a scraper. The wettable powder mixer disclosed by the invention is high in material shearing and stirring speed and uniform in mixing; and a heating phenomenon in the material mixing processis reduced, the materials are prevented from being agglomerated when heated, and materials adhered onto the stirring shaft are reduced. The mixer disclosed by the invention is novel in structure, small in occupied area, low in cost, convenient to maintain and suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of wettable powder preparation, in particular to a wettable powder mixer. Background technique [0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. In the process of mixing, it can also increase the contact surface area of ​​materials to promote chemical reactions; it can also accelerate physical changes. [0003] Commonly used mixers are divided into four categories: gas and low-viscosity liquid mixers, medium-high viscosity liquid and paste mixers, and powder and granular solid material mixing machines. [0004] Pesticide formulations mainly include powders, wettable powders, emulsifiers, emulsifiable concentrates, suspension concentrates, granules, water formulations, etc. Most of the original medicines in my country are processed into wettable powders and emulsifiable concentrates. It is convenient for storage and transportation, and is a new and st...

AI Technical Summary

Problems solved by technology

[0005] The use of wettable powder in the prior art has the following problems: uneven particle size distribution and uneven particle size, resulting in unstable performance of the prepared suspension, prone to precipitation, suspension, stratification and other phenomena; therefore, in the mixing process of materials Mix evenly and fully in the middle, so that the final crushed particles are uniform

[0006] Existing material mixers have the following problems when mixing wettable powder raw materials: 1. The existing ribbon mixing speed is slow. When mixing wettable powder, due to the exothermic mixing of raw materials, the exothermic process causes agglomeration, It affects the performance of the material. At the same time, the agglomerated material affects the particle size distribution of the subsequent wettable powder. 2. The material is easily adsorbed to the tank wall of the mixing tank, which affects the mixing efficiency. At the same time, the adhered material is mixed unevenly ; Therefore, fast mixing is required to reduce the agglomeration caused by exothermic mixing of raw materials
