Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The specific embodiment of the utility model will be described in further detail below in conjunction with the schematic diagram.

As shown in Figure 1, a spiral self-cleaning filter includes an upper cover 100, a filter cylinder 200, a transmission motor 1, a Y-shaped sealing ring 2, a filter screen fixing frame 3, a wedge-shaped filter screen 4, and a discharge port 5. The slag discharge chamber 6, the positioning bearing 7, the feed port 9, the screw shaft 11 and the slag collection chamber 12, the upper cover 100 is arranged on the upper part of the filter cylinder 200, and the transmission motor 1 is arranged on the upper part of the upper cover 100.

The feed port 9 is arranged on the side of the filter cylinder 200 top, the discharge port 5 is arranged on the side of the filter cylinder 200 bottom, and the wedge-shaped filter screen 4 is arranged on the bottom of the feed port 9 to the discharge port 5 The inner side of the filter cylinder 200 below.

The filter screen fixing frame 3 is arranged on the inner side of the filter cylinder 200 on the top of the wedge-shaped filter screen 4 , and the filter screen fixing frame 3 is supported on the bottom of the upper cover 100 .

The screw shaft 11 is inserted inside the wedge-shaped filter screen 4 , and the power rod of the screw shaft 11 passes through the filter screen fixing frame 3 and the upper cover 100 and is axially connected with the transmission motor 1 .

The slag collection chamber 12 is arranged inside the filter cylinder 200 at the bottom of the wedge-shaped filter screen 4 , and the inside of the slag collection chamber 12 communicates with the inside of the wedge-shaped filter screen 4 .
