Description

Apparatus for reducing the vibration of a mixer used in manufacturing an electrode slurry The present invention relates to a mixer for manufacturing an electrode slurry, and more specifically, to a device for reducing vibration of the mixer. Electrode slurry (e.g., positive electrode slurry) is a mixture that plays an important role in the manufacturing process of batteries (e.g., lithium-ion batteries). To manufacture such electrode slurries, a mixer is generally used. The mixer consists of a structure in which a mixing blade called a rotor rotates to mix the electrode slurry, and a vessel, which is a container for holding the electrode slurry, rotates. The mixing operation of this mixer proceeds by mixing the electrode slurry inside the vessel as the rotor and the vessel rotate. At this time, vibration occurs in the vessel due to the rheology of the electrode slurry. The vibrations from these vessels are transmitted not only to the exterior of the equipment but also to the floor, being strong enough to threaten workers. This intensifies as the working volume increases, leading to a decrease in production output. The following drawings attached to this specification illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the detailed description of the invention provided below; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings.
