IMPROVED MIXER SUSPENSION SYSTEM

摘要

Suspension apparatus and method for balancing and damping vibration in liquid vortex mixers pivotably supporting a mixing frame assembly and suspending the assembly by at least one spring for mixing a liquid, including adjusting the lowest rotational resonant frequencies of the mixing frame assembly to be substantially below the lower of a pair of forcing function frequencies corresponding to spin and orbit velocities. A pivoting support is located between the mixing frame assembly and a base. A damper in the form of an annular ring is used to damp pivoting movement of the mixing frame assembly. A bushing provides accommodation of a misaligned spring mounting end turn using a V-groove to retain the spring mounting end turn, and may include an eccentric feature to allow adjustment of the spring mounting length.
