[0009] Furthermore, the heating plate includes a connecting portion fixedly connected to the middle of the double-cone tank body, and both ends of the connecting portion are fixedly connected to guide portions corresponding to the two ends of the double-cone tank body.

[0010] Furthermore, a filter head is provided on the vacuum tube.

[0011] Furthermore, a feeding funnel is provided on the feeding pipe.

[0012] Furthermore, valves are provided on the feed pipe and the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
