In the present embodiment, the cleaning surface of the cleaning mechanism is in contact with the trap mechanism 2 when the cleaning operation is not performed. Adopt foretell middle recovery mechanism 100 that can generate electricity, when clearing up the recovery to one-level recovery unit 200, the plastic powder on sack filter core 201 enters into passageway 10 through the opening of retrieving body 1 one end through the exit end of one-level recovery unit 200 and holds back through the mechanism 2 that holds back of retrieving the body 1 other end again, make the plastic powder be held back on the terminal surface towards passageway 10 who holds back mechanism 2, rethread driving piece drive drives cleaning component 3 and cleans the plastic powder on holding back mechanism 2, make the plastic powder fall under the action of gravity in collecting mechanism 4, thereby make the plastic powder obtain further recovery, avoid the direct economic loss and the environmental pollution problem that cause in reaching second grade recovery unit 300 through pipeline 400 of a large amount of different colours plastic powder, improve the recycle ratio of plastic powder greatly. Because the fan forms the wind current in pipeline 400 when second grade recovery unit 300 starts, the wind current drives aerogenerator work and generates electricity and drives simultaneously and clean part 3 and rotate, that is to say, aerogenerator work need not to rely on the power, only rely on the wind current that the fan formed in pipeline 400 when starting can rotate automatically, the consumption of electric energy has been practiced thrift greatly, the manufacturing cost of enterprise has been reduced, the generator electricity generation can supply power for lighting device and the plastic spraying machine of spraying plastics equipment in the workshop simultaneously, the consumption of electric energy has further been reduced.
