[0054] First, use the adjustment unit 7 to adjust the angle of the filter net 10, then use the support auxiliary part 85 to adjust the height of the two filter nets 10, and then make a connection. Let the vibration unit 8 vibrate on the filter net 10. The pulp enters from the A liquid inlet housing 4 and flows to the upper filter net 10. Let the filtered pulp flow to the guide plate 15 and finally enter the B liquid inlet housing 5. Then it flows from the B liquid inlet housing 5 to the lower filter net 10. The residue on the upper filter net 10 will flow to the collection housing 14 under the action of the angle of the filter net 10 and the liquid. The pulp filtered by the lower filter net 10 will fall into the space formed between the partition plate 17 and the outer housing 1. The pulp blocked by the lower filter net 10 will flow to the collection tank 6. Then collect and process the corresponding pulp. Regularly clean the filter net 10 through the cleaning unit 9 and the strip-shaped cleaning brush 3 to reduce the probability of the filter net 10 being blocked.
