Efficient novel rotary drying device for mica pearlescent pigment processing

Abstract

The invention relates to the technical field of pearlescent pigment processing, and discloses an efficient novel rotary drying device for mica pearlescent pigment processing, which comprises a mounting frame, a metal roller capable of drying various pigments is rotatably mounted in the mounting frame, and an electromagnetic assembly capable of heating the metal roller is further arranged on the mounting frame. A revolution assembly and a rotation assembly which can drive the metal roller, the scattering drying cylinder and the pearlescent pigment drying cylinder to rotate are arranged in the mounting frame and the metal roller correspondingly, and a vibration assembly which can slow down the discharging speed of the mica pearlescent pigment is arranged in the kidney-shaped pipe. Compared with a traditional air blowing drying mode, the drying efficiency is improved, pigment scattering and waste are avoided, in addition, the length of a pigment drying channel is increased, the mutual extrusion influence between the pigments is relieved, the scratch influence on the surface of the mica pearlescent pigment is relieved, and the optical effect of the pigment is improved.

Description

technical field [0001] The invention relates to the technical field of pearlescent pigment processing, in particular to a high-efficiency novel rotary drying device for mica pearlescent pigment processing. Background technique [0002] Pearlescent pigments are micropowders made of natural mica flakes as the base material, which are continuously coated with one layer or alternately coated with multiple layers of metal compounds by a special preparation process. It is completely non-toxic and has many specifications and models. It has been widely used in coatings, plastics, textiles, papermaking, leather, glass, ceramics, cosmetics, decorations, building materials and automobile industries. It is deeply loved and favored by users. The development and application prospects are very broad. Pearlescent pigments need to be dried during production. [0003] In the prior art, when the pigment is dried, the mica pearlescent pigment and the light-scattering pigment are often dried u...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-efficiency new rotary drying device for mica pearlescent pigment processing, which has the advantages of uniform heating and is not easy to cause mechanical damage to the pigment, and solves the problem of high shear in the existing drying methods. The shearing drying method is easy to cause mechanical damage to the surface of the pigment particles and other problems
