[0029] When the present embodiment is used, when the centrifuge is needed in the preparation of acetic acid, the staff connects the external power cord 4 to the power supply, pulls the movable cover 6 to rotate it through the hinge 7, thereby opening the centrifuge housing 1, places the vessel in the rotating frame assembly 3, then pulls the movable cover 6 back to the original position, unscrews the sealing cover 572 in the closing assembly 57 in the filtering and heating device 5, pours the acetic acid into the connecting box 51, and then installs the sealing cover 572 back through the thread, and the filter cloth 56 filters the acetic acid.

The filtered acetic acid falls to the inner bottom of the connecting box 51. When necessary, the staff can start the electric heating rod 52 to heat the acetic acid, and then open each valve 55. The acetic acid enters the centrifuge housing 1 through each connecting pipe 54 and then falls into the vessel. The motor assembly 2 is operated to drive the rotating frame assembly 3 to rotate, thereby driving the vessel and the acetic acid therein to rotate, thereby performing centrifugal work. The staff can observe the internal situation of the connecting box 51 through the observation window 571 when necessary.

[0030] Example 2
