2) starting a rotating motor, rotating a shaft of the rotating motor, wherein the rotating direction of the shaft of the rotating motor is opposite to the spiral direction of the hollow spiral plate, the shaft of the rotating motor drives a rotating conveying pipe to rotate, the rotating conveying pipe drives the hollow spiral plate to rotate, and the rotating direction of the hollow spiral plate is opposite to the spiral direction of the shaft of the rotating motor, so that tail gas can flow along the hollow spiral plate;
3) under the action of the weak magnet sheet, metal powder in the tail gas and a small amount of airflow enter the hollow spiral plate through the guide hole, the metal powder gets rid of the attraction of the weak magnet sheet under the rotation action, enters the rotary conveying pipe along the hollow spiral plate in a spiral manner, flows to the other end of the rotary conveying pipe under the action of the airflow, and then enters the separation pipe;
4) under the action of the adsorption force of the aggregate electromagnet, metal powder enters a collection cavity in the collection box through the first collection pipe, the metal powder which does not enter the first collection pipe enters the second collection pipe through the further attraction of the guide electromagnet, and the magnetism of the aggregate electromagnet is greater than that of the guide electromagnet, so that the metal powder in the second collection pipe also enters the collection cavity in the collection box for collection;
5) the residual airflow enters the tail discharge pipeline again through the filter screen to be discharged, and meanwhile, the guide electromagnet and the aggregate electromagnet can adsorb a small amount of metal powder on the filter screen to prevent the metal powder from blocking the filter screen;
6) the staff can observe the collection condition of the metal powder in the case that gathers materials, and after the metal powder in the case that gathers materials accumulated to a certain degree, open the shutoff stopper, with discharging pipe and powder collecting vessel intercommunication, retrieve the metal powder.
