Powder dispersion and drying device

Abstract

The invention discloses a powder dispersion and drying device. The powder dispersion and drying device comprises a bottom frame, a powder inlet, a dispersion chamber, a stirrer, an automatic valve, adrying chamber, a first conveying belt, a second conveying belt, heating devices, a thermal insulating plate and a powder outlet. The bottom frame is connected with the drying chamber, the dispersionchamber is located right above the drying chamber, the automatic valve is located below the stirrer, the first conveying belt is located above the second conveying belt, the heating devices are arranged on the left side and the right side of the drying chamber, and the powder outlet is located below the left end of the second conveying belt. According to the powder dispersion and drying device, the stirrer is transversely installed to avoid dispersion dead angles, and the first conveying belt and the second conveying belt are used for conveying materials in the drying chamber to ensure the complete drying of the powder. The powder dispersion and drying device integrates dispersion and drying functions, greatly simplifies production and processing procedures of the powder, has the advantages of being simple in structure, simple and convenient to operate and good in process continuity, and is easy to popularize and use industrially.

Description

technical field [0001] The invention relates to a powder dispersing and drying device, which belongs to the technical field of powder equipment. Background technique [0002] For single-component powders, excessive water content will increase powder agglomeration, affecting product performance when used as fillers or directly; for deep-processing or modified powders, complete removal of solvents can ensure product stability. Therefore, in the actual production process, especially for micronano-scale and easily agglomerated powders, the dispersion and drying process is particularly important for the service life and performance of the product. [0003] Existing powder dispersion adopts cylinder type and box type agitator to disperse the powder, the stirring is prone to dead angle, and it needs to be shut down to take out after stirring and dispersing, the process continuity is poor and the efficiency is low; the drying process adopts centrifugal spray dryer or flash evaporati...
