Furthermore, the filter plate adopts high-strength filter cloth which is detachably connected with the bin walls of the grinding bin and the mixing bin respectively. The connecting parts of the high-strength filter cloth, the grinding bin and the mixing bin can be provided with extension ears which are connected by bolts.
Further, the ultrasonic generator is connected with the screw propeller.
