The existing electric mechanical vibration table can only adjust the frequency during use, but cannot adjust the amplitude and waveform, and is gradually replaced by the hydraulic vibration table. However, the crystallizer hydraulic table, especially the vibration cylinder of the crystallizer hydraulic vibration, is difficult to inspect and maintain.

The rod heads of the first clamping pin and the second clamping pin 2322 are inclined, and the inclined notches of the first locking groove and the second locking groove 2323 are in opposite directions and are arranged symmetrically. The advantage of such an arrangement is that the clamping devices on both sides are self-centering, so that the arc-shaped crystallizer hydraulic vibration table 1 is firmly fixed.
