Abstract

The invention discloses a powder surface modification device which comprises a charging barrel composed of a barrel body, a barrel bottom and a barrel top and a stirrer arranged in the charging barrel, wherein the barrel top is provided with a gas outlet used for discharging gas, the barrel bottom is provided with a gas inlet, a permeable plate is arranged in the gas inlet, the permeable plate allows gas to enter the charging barrel and does not allow powder to flow out of the charging barrel, the gas inlet is communicated with an air source and is used for guiding inlet air into the charging barrel, and the stirrer comprises a first group of blades arranged in the bottom of the charging barrel and a second group of blades arranged in the top of the charging barrel. The invention also provides a method for conducting power surface modification by using the device. The powder surface modification device and method have the advantages of being uniform in modification temperature, rapid in temperature rising and cooling, small in powder breakage rate, high in modified powder yield, small in comprehensive energy consumption, small in equipment abrasion, free of particle attachment to the inner wall of equipment and the like.

Description

technical field [0001] The invention relates to the technical field of powder surface modification, in particular to a powder surface modification device and a method for surface modification of powder by using the powder surface modification device. Background technique [0002] In order to adapt to various applications, surface modification is widely used in various powders, such as inorganic, organic, metal and other powders. Among various surface modification methods, dry modification is one of the most commonly used methods, which mainly includes adding surface modifiers to dry powder, and coating the powder under specific equipment and process conditions. After treatment, the modified powder can be obtained. Examples of commonly used powder surface modification devices include: SLG type continuous powder surface modification machine, high-speed heating mixer, high-speed impact powder surface modification machine, PSC type powder surface modification machine, horizonta...
