Powder heating and drying device

Abstract

The invention discloses a powder heating and drying device. The powder heating and drying device comprises a drying furnace, a material conveying mechanism, and a heating mechanism, wherein a vacuum drying cavity is formed inside the drying furnace; the material conveying mechanism comprises a material conveying vehicle, material boxes and a first driving assembly, the material boxes are arrangedon the material conveying vehicle, and the first driving assembly is used for driving the material conveying vehicle to enter and exit the vacuum drying cavity in the material conveying direction; andthe heating mechanism comprises heating plates and a second driving assembly, the heating plates are contained in the vacuum drying cavity, and the second driving assembly is used for driving the heating plates to make contact with or be separated from the material boxes. The powder heating and drying device has the advantages of being fast in heating speed, high in heating efficiency and high inheat effective value utilization, and the rapid and effective drying treatment process of battery powder or medicine powder and the like in the material boxes is achieved; and moreover, a contact type heating and heat radiation heating dual-heating mode is adopted, and the material boxes are uniformly heated favorably, so that the heating uniformity of materials such as the battery powder or themedicine powder is improved, the performance consistency of batteries or medicines and the like is maintained favorably, and the product yield is improved.

Description

technical field [0001] The invention relates to the technical field of vacuum drying, in particular to a powder heating and drying device. Background technique [0002] There are three main methods of heat transmission: radiation, convection, and conduction. Among them, thermal radiation is a phenomenon in which an object emits electromagnetic waves to the surrounding due to its temperature, and the heat transfer efficiency is low; heat convection makes objects at different temperatures heat up through the flow of fluid. Exchange, the heat transfer efficiency is low; heat conduction spreads from a place with high temperature to a place with low temperature through solid heat, and the heat transfer efficiency is high. At present, in new energy batteries, medicines and other material powder heating and drying devices, a single heat transmission method is often used, which leads to uneven heating of batteries, medicines and other materials during the drying process. The perfor...
