[0027] And when the need to recover these blocked solid impurities, start drive motor 2, through its output shaft, drive the rotating rod 21, so that the activity frame 33 in turn with each cavity 14 mutual alignment, when the two are mutually symmetrical, start the fan 34, through the air inlet pipe 3, can be guided to the outside air into the separation tank 1, and through the upper and lower two sides of the limiting rotary frame 32, through hole 36 and activity frame 33, can be the first filter screen 15 surface of the solid impurities blocked to the recovery pipe 31, realize the effect of recycling solid impurities.
