Description

Apparatus for reducing vibration of mixer for manufacturing electrode paste Cross Reference to Related Applications The present application claims priority and benefit from korean patent application No. 10-2024-0156602 filed in the korean intellectual property office on month 11 and 6 of 2024, the entire disclosure of which is incorporated herein by reference. Technical Field Aspects of embodiments of the present disclosure relate to an apparatus for reducing vibration of a mixer for manufacturing of electrode slurry. Background Electrode pastes (e.g., positive electrode pastes) are mixtures that perform important functions in the manufacturing process of batteries (e.g., lithium ion batteries). Mixers are commonly used to manufacture electrode slurries. The mixer has a structure in which mixing blades called a rotor and a container containing electrode slurry are rotated to mix the electrode slurry. The mixing operation of such a mixer is performed according to a method of mixing electrode paste contained in a container while rotating a rotor and the container. During mixing, vibrations occur in the vessel due to the rheology of the electrode slurry. Such vibrations of the container may be large vibrations transmitted to the outside of the facility and the floor, resulting in the risk to workers in the vicinity. Vibrations increase with increasing workload, resulting in a reduced yield of product. Disclosure of Invention According to embodiments of the present disclosure, an apparatus is provided that may reduce vibrations of an inner vessel that occur during (or during) a mixing operation of a mixer for manufacturing an electrode slurry. Further, embodiments of the present disclosure provide an apparatus that can reduce vibration of an outer container occurring in a mixing operation of a mixer for manufacturing an electrode slurry. Further, embodiments of the present disclosure provide an apparatus that can reduce vibrations of the inner vessel and the outer vessel occurring in a mixing operation of a mixer for manufacturing electrode slurry. An apparatus for reducing vibration of an inner container occurring in a mixing operation of a mixer for manufacturing an electrode slurry includes a rotating roller member between the inner container and an outer container extending around the inner container, and a damping cylinder on the outer container and configured to absorb vibration transmitted through the rotating roller member to reduce vibration. According to another embodiment of the present disclosure, an apparatus for reducing vibration of an outer container occurring in a mixing operation of a mixer for manufacturing an electrode slurry includes a link member in contact with the outer container and configured to rotate based on the vibration of the outer container, and a hydraulic cylinder configured to absorb the vibration of the outer container transmitted by the rotation of the link member to reduce the vibration. According to another embodiment of the present disclosure, an apparatus for reducing vibrations of an inner container and an outer container occurring in a mixing operation of a mixer for manufacturing an electrode slurry includes a first vibration prevention apparatus configured to reduce vibrations of the inner container, and a second vibration prevention apparatus configured to reduce vibrations of the outer container extending around the inner container. The first vibration preventing apparatus includes a rotating roller member between the inner container and the outer container, and a damping cylinder on the outer container and configured to absorb vibration transmitted through the rotating roller member to reduce vibration, and the second vibration preventing apparatus includes a link member in contact with the outer container and configured to rotate based on the vibration of the outer container, and a hydraulic cylinder configured to absorb vibration of the outer container transmitted by the rotation of the link member to reduce vibration. According to the embodiments of the present disclosure, the rotating roller member may be interposed between the inner container and the outer container together constituting the container, and the damping cylinder on the outer surface of the outer container may receive and reduce vibration of the inner container, which occurs due to rheology of the slurry contained in the inner container, in the mixing operation of the mixer, by the rotating roller member, and thus vibration of the inner container may be effectively prevented. Further, the hydraulic cylinder provided on the outer periphery of the outer container can receive and reduce the vibration of the outer container, which occurs due to the rheology of the slurry occurring in the mixing operation of the mixer, through the link member, and thus the vibration of the outer container can be effectively prevented.
