8. The energy-saving and environmentally friendly civil engineering construction waste treatment device according to claim 1 is characterized by: The surface of the recovery tube (1) is fixedly connected to a water outlet box (2), the inner wall of the water outlet box (2) is fixedly connected to a plurality of atomizing nozzles (43), the inner wall of the recovery tube (1) is fixedly connected to a slag discharge tube (3), the bottom end of the atomizing nozzle (43) extends to the interior of the slag discharge tube (3), and the inner wall of the recovery tube (1) is fixedly connected to a placement tube (4).

9. A method for using an energy-saving and environmentally friendly civil engineering construction waste treatment device according to any one of claims 1 to 8, characterized in that: The method comprises the following steps: Step 1: When in use, the motor (5) is started, and the construction waste is placed into the recovery barrel (1) through the placement barrel (4). The output end of the motor (5) drives the driving shaft (6) and the spur column (16) to rotate. The rotation of the spur column (16) drives the second face gear (13) and the first face gear (7) to rotate inversely relative to each other, thereby driving the first crushing roller (11) and the second crushing roller (12) to rotate inversely to crush the construction waste. The driving shaft (6) rotates to drive the first driving wheel (40) to rotate. The first driving wheel (40) drives the first driven wheel (35) to rotate through the first belt (31). The first driven wheel (35) drives the rotating shaft (15) to rotate. The rotating shaft (15) drives the pair of annular wave grooves (26) to rotate, so that the pair of L-shaped plates (25) reciprocate under the guidance of the spherical protrusion (39) along the annular wave groove (26). Step 2: The crushed powder falls through the slag discharge hole (23) onto the inclined plate (32), the rotating shaft (15) rotates through the second driving wheel (33) to drive the second belt (36) to move, the second belt (36) drives the linkage shaft (38) to rotate through the second driven wheel (34), the linkage shaft (38) rotates to drive the first bevel gear (28) to rotate, the first bevel gear (28) rotates to drive the second bevel gear (29) to rotate, the second bevel gear (29) rotates to drive the sweeping brush (30) to rotate, the sweeping brush (30) rotates to clean the construction waste accumulated on the surface of the inclined plate (32), in this process, a plurality of atomizing nozzles (43) spray the clean water in the water outlet box (2) in an atomized form, and the water is adsorbed by dust in the air to reduce dust; Step 3: When it is necessary to adjust the distance between the first crushing roller (11) and the second crushing roller (12), the operator rotates the worm (42), the worm (42) drives the turbine (17) to rotate, the turbine (17) drives the bidirectional screw (18) to rotate, and then drives the second slider (8) and the first slider (19) to move closer to or farther away from each other, thereby controlling the distance between the first crushing roller (11) and the second crushing roller (12). At this time, after the second face gear (13) adjusts the distance, it is always meshed with the spur column (16), and after the first face gear (7) adjusts the distance, it is always meshed with the spur column (16), thereby ensuring the normal operation of the crushing operation.
