[0035] Working principle:

[0036] First, the mounting frame 23 and the auxiliary support frame 24 are stably placed in the working environment, the fermentation kettle 11 is installed on the surface of the mounting frame 23 by welding, the top cover 21 is installed on the upper end of the fermentation kettle 11 by the mounting mode of flange and bolt, the tightness of installation is ensured, the stirring motor is arranged on the upper end of the top cover 21, the inlet and outlet are arranged in the fermentation kettle 11, when carrying out the fermentation work, the material is put into the fermentation kettle 11 along the inlet of the fermentation kettle 11, the material is sealed and fermented in the fermentation kettle 11, the motor arranged on the upper end of the top cover 21 can drive the stirring rod to rotate and stir to assist the fermentation work in the fermentation process, the material treated by fermentation is discharged through the outlet of the fermentation kettle 11 for subsequent treatment.

When the first circular ring clamp 12 and the second circular ring clamp 13 are slidably close to each other, the cylindrical block 18 connected to the upper end of the second circular ring clamp 13 is slidably attached to the surface of the first clamping ring 15 and the second clamping ring 16, and when continuously sliding close, the cylindrical block 18 is extruded to rotate the first clamping ring 15 and the second clamping ring 16 through the arc surface of the cylindrical block 18.
