Abstract

The present invention relates to a blade that prevents excessive shifting of powder in a rotating reactor and induces smooth passing of powder to ensure uniform powder coating, and to a reactor for a powder coating device equipped with the same. The blade is formed such that a plurality of blades are spaced apart from one another along the circumference of the inner surface of a cylindrical reactor body that receives powder, are formed to be long from left to right and installed along the length direction of the reactor, and have a shape in which the cross-sectional width gradually narrows from the lower surface that is in close contact with the inner surface of the reactor body toward the upper part, thereby enabling smooth passing of powder as the reactor rotates.

Description

Blade for uniform coating of powder and reactor with the same The present invention relates to a blade and a reactor for a powder coating device equipped with the same, and in particular, to a blade and a reactor for a powder coating device equipped with the same that prevents excessive shifting of powder in a rotating reactor while inducing smooth flow of powder so that powder coating is performed uniformly. With the recent expansion of the market for ultrafine nanoscale powders, various methods are being researched and developed to form high-quality thin films on large volumes of powder. For example, thin-film coated powder can improve the electrochemical and mechanical properties of batteries, and is therefore receiving attention as a technology that can lead the advanced semiconductor/battery market, such as active materials for cathode/anode materials and slurries for CMP (Chemical Mechanical Polishing). To coat such nanoscale thin films, processes such as CVD (chemical vapor deposition) and ALD (atomic layer deposition) can be applied. Among these, the P-ALD (Powder-Atomic Layer Deposition) method includes a reactor optimized for powder coating and is a technology that enables atomic layer deposition on the particle surface by maximizing the dispersion of the loaded powder. However, conventional rotary thin film deposition processes have several drawbacks. Due to the small internal volume of conventional reactors, the amount of powder that can be loaded per process is relatively small, resulting in a lower yield required for actual mass production. Additionally, manual connection between the reactor and chamber is required for each process, which limits the reduction of production time. To address these issues, mass production coating technologies and equipment structures that do not require manual connection of the reactor are being proposed. However, while these conventional technologies allow for a certain degree of automation in the connection between the reactor and the chamber, the problem of requiring human labor and manual operation during the powder recovery process still persists. In particular, although existing ultrafine nano-level powder coating technologies have faced difficulties in commercial production, efficient automated mass production technologies capable of continuous large-scale production—considering the unique nature of the coating target being powder—have not yet been proposed. In particular, for the reactor, a key component in powder coating systems, improvements were required to enhance the uniform coating capability of the powder.
