Abstract

The invention relates to a method and a device for continuously feeding and mixing dry powder. The device comprises a plurality of feeding devices, a vertical mixer and a horizontal mixer. The feedingdevices are communicated with a plurality of first feed inlets in a side wall of the vertical mixer; a first discharge hole of the vertical stirrer is communicated with a second feed inlet of the horizontal mixer; a plurality of first feed inlets upwards inclined at a preset angle are formed in the side wall of the vertical mixer; a circulation feed inlet of a circulating device is communicated with the bottom part of the horizontal mixer; a circulation discharge hole of the circulating device is communicated with the upper part of the horizontal mixer. According to the method and the devicefor continuously feeding and mixing the dry powder provided by the invention, the feeding devices, the vertical mixer and the horizontal mixer are adopted, and during a mixing process, the circulatingdevice conveys mixed dry powder located on the bottom part of the horizontal mixer to the upper part of the horizontal mixer, so that continuous feeding can be realized; after the various dry powderare fully mixed through the vertical mixer and the horizontal mixer, the advantages of uniformity in mixing, high mixing efficiency, capability of continuously feeding and the like are realized.

Description

technical field [0001] The invention relates to a dry powder continuous feeding and stirring method and equipment, in particular to a dry powder continuous feeding and stirring method and equipment suitable for lithium battery electrode dry powder thermal composite coating. Background technique [0002] The coating of the existing lithium-ion electrodes all adopts wet coating. This wet coating is to mix the active material of the lithium-ion battery with the corresponding organic solvent, and then transfer coating or extrusion coating. In the form of a cloth, it is applied to the substrate. After coating in this coating method, a very long baking device is required to dry and bake the coated electrode to remove the organic solvent and water in the electrode active material. If the baked organic solvent is not recycled and discharged directly into the air, it will cause air pollution. If it is recycled, it will increase the user's fixed asset investment and operating costs. ...
