[0028] The air in the crushing cylinder 1 is pumped into the gas storage tank 4 through the air guiding ring 2 and the air duct 3, so that the inside of the crushing cylinder 1 is in a negative pressure state, avoiding the powder generated by crushing from entering the external air. At the same time, a liquid is filled in the lower part of the air duct 3, and the powder contained in the air pumped out by the air duct 3 will stay in the liquid, which is convenient for subsequent treatment.

[0029] In order to reduce the entry of powder into the air guide ring 2 and generate a downward impact force during exhaust, the top surface of the air guide ring 2 is an inclined surface with an outer high and inner low shape. A plurality of through holes are evenly distributed on the circumference of the top surface of the air guide ring 2. The two ends of each through hole are respectively communicated with the air guide ring 2 and the crushing cylinder 1. A baffle 5 is fixedly arranged above the air guide ring 2. The baffle 5 is annular and is arranged parallel and at intervals with the top surface of the air guide ring 2. The outer wall of the baffle 5 is hermetically connected to the inner wall of the crushing cylinder 1. The through holes are located on one side of the top plate of the air guide ring 2 close to the inner wall of the crushing cylinder 1.

[0030] In order to facilitate the treatment of liquid containing toxic powder, an inlet and outlet pipe 6 is communicated and arranged at the bottom of the air guide pipe 3, and a valve is arranged on the inlet and outlet pipe 6.
