A screening device with a cyclic wave structure according to claim 1, characterized in that, the vibrating screen assembly (8) includes a vibrating motor (801), and the output end of the vibrating motor (801) is connected to There is an eccentric wheel (802), and the output end of the eccentric wheel (802) is provided with an eccentric shaft (803), the surface of the eccentric shaft (803) is covered with a vibrating rod (804), and one part of the vibrating rod (804) The side is connected with a screening plate (805). 9. A screening device with a cyclic undulation structure according to claim 8, characterized in that the size of the sieve hole on the top screening plate (805) is larger than that on the bottom screening plate (805) hole size. 10. A screening method provided with a cyclic wave structure, comprising the following steps: S1. Preliminary filtration: adjust the motor (401) to make the connecting rod (404) drive the bracket (403) to rotate through the drive shaft (405), so that the first filter plate (402) and the second filter plate (406) are tilted at the same time, and the right end and the screening The heights of the plates (805) are consistent, and industrial waste is put into the filter chamber (407) through the feed port (2) so that it can be filtered through the filter plate one (402) and the filter plate two (406) and then put into the screening plate (805) for screening point; S2. Vibration screening: the vibration motor (801) drives the vibration rod (804) to vibrate through the eccentric shaft (803) on the eccentric wheel (802), so that the screening plate (805) moves up and down, left and right, and vibrates the industrial waste Sieving, two sets of sieving plates (805) can classify and sieve garbage of different sizes; S3, cycle fluctuation: the 2D rubbish screened out initially moves to the left and re-enters the filter plate 1 (402) and the filter plate 2 (406), and puts the 2D garbage into the sieve plate (805) again after being filtered again, and the cycle is repeated several times until the screening work is completed; S4. Metal screening: the belt motor (606) drives the transmission rod (604) to move left and right through the driving wheel (605), the driven wheel (602) and the transmission belt (603), and the electromagnet (607) generates magnetism after being energized, which is beneficial to industrial The metal in the garbage is adsorbed and transported to the discharge port one (3), and the separation can be completed after the electromagnet (607) is powered off; S5, garbage discharge: adjust the motor (401) to make the connecting rod (404) drive the bracket (403) to rotate through the drive shaft (405), so that the filter plate one (402) and the filter plate two (406) rotate to the left, and the left end and The 2D outlets (15) are compatible with each other to discharge 2D garbage, while the particulate matter is discharged into the second outlet (12), and other large-sized garbage is respectively put into the third outlet (13) and the first outlet (3) according to the volume of garbage. ).
