A layer of sieve is covered on the supporting rod.

The beneficial effects of the utility model are as follows: the utility model includes a frame, and a tapered drum screen is arranged in the frame, and the tapered drum screen is arranged horizontally. One end of the small diameter is a material inlet, and the end of the large diameter is a discharge port. Mouth; the lower part of the tapered drum screen is provided with a flow groove, the flow groove is inclined, and it is higher at the large-diameter end of the tapered drum. Through the above structural settings, driven by the driving device, the tapered trommel can be driven to rotate in situ. By injecting the mixed material at the small-diameter end, the liquid will be filtered through the screen while the material is rolling toward the large-diameter end. The final liquid is discharged to the outside through the flow tank, and the solid material is discharged at the discharge port with the rotation of the tapered drum screen.

The utility model uses the entire tapered drum screen as a filtering stroke, and the solid material and the liquid material travel in opposite directions, and the solid material and the liquid material can be effectively separated when the tapered drum screen rotates. The utility model has the advantages of simple and novel structural design, convenient use and high filtering efficiency, and is an ideal filter for plastic impurities.
