[0031] In the prefabricated screening building of this embodiment, its first floor module 1, second floor module 2, third floor module 3, fourth floor module 4 and vibrating screen 5 are all processed into finished products in the factory. When they are needed at the construction site, the first floor module 1, second floor module 2, third floor module 3, fourth floor module 4 and vibrating screen 5 are transported to the construction site in a split manner and hoisted and assembled on site. The specific hoisting and assembling method is as follows:

[0032] First, hoist the first floor module 1 to the designated position and fix its bottom to the foundation of the infrastructure. Then hoist the second floor module 2 above the first floor module 1, dock the vibrating screen discharge hopper 24 with the first layer discharge hopper 18, dock the vibrating screen feed hopper 23 with the belt conveyor distribution hopper 17, and dock the second layer exhaust air duct 21 with the first layer exhaust air duct. Then fix the second floor module 2 and the first floor module 1 by bolt connection. Next, hoist the third floor module 3 above the second floor module 2, dock the bottom of the dust collector box body 31 with the dust collector discharge hopper 22; dock the air inlet of the dust collector box body 31 with the second layer exhaust air duct 21. Then, fix the third floor module 3 and the second floor module 2 with bolts. Hoist the vibrating screen 5 into the vibrating screen installation space 33 of the third floor module 3, make the discharge port of the screen body dock with the vibrating screen feed hopper 23; make the bottom surface of the screen body and the vibrating screen discharge hopper 24 dock, and then fix the vibrating screen 5. Finally, hoist the fourth floor module 4 above the third floor module 3, make the vibrating screen distribution hopper 45 dock with the feed inlet of the vibrating screen 5, dock the lower port of the dust collector exhaust pipe 42 with the clean air outlet of the dust collector box body 31, and then fix the third floor module 3 and the fourth floor module 4 with bolts.

Finally, install the feeding belt conveyor on the feeding belt conveyor space 41 on the top surface of the fourth floor module 4.

[0033] When performing screening work, the sand and gravel aggregates to be processed are transported to the vibrating screening bin 45 on the top surface of the fourth floor module 4 through the feeding belt conveyor. Under the action of gravity, the sand and gravel aggregates to be processed enter the vibrating screen 5. The dust collector and the fan 43 in the dust collector box 31 and the vibrating screen motor 44 are turned on, and the vibrating screen 5 works. After the sand and gravel aggregates to be processed are screened, the coarse materials enter the belt conveyor distribution bin 17 through the pre-vibrating screen bin 23 and are then transported to the designated position through the finished product belt conveyor 12; the fine materials enter the vibrating screen discharge bin 24 from the bottom of the vibrating screen 5 and then fall into the first layer discharge bin 18, and are then transported to the designated position through the finished product belt conveyor 12. During the screening process, the dust generated in the first floor module 1 enters the dust collector box 31 through the first layer air extraction duct 11 and the second layer air extraction duct 21 for gas-solid separation. The clean gas is discharged through the dust collector exhaust duct 42, and the dust falls into the dust collector discharge bin 22 and then drops, and is sent to the finished product belt conveyor 12 by the screw conveyor 16 to be mixed with the fine materials.
