[0024] Among them, a second water pump 15 is arranged in the raw material tank 4. The brand of the second water pump 15 is Tiffany, model JSSB-0328. By setting the second water pump 15, the separation liquid remaining after separation in the centrifugal drum 9 is pumped to the reflux pipe 16. The water outlet end of the second water pump 15 is installed with a transport pipe 3.

[0025] Among them, one end of the transport pipe 3 passes through the separation shell 2 and the side wall of the centrifugal drum 9 and is fixedly connected to a first water pump 12. The brand of the first water pump 12 is Tiffany, model JSSB-0328. By setting the first water pump 12, the separation liquid can be pumped into the centrifugal drum 9 for centrifugal separation.
