Dust removal device with screening function

The utility model discloses a dust removal device with a screening function, which comprises an air inlet box, an air inlet is arranged at one end of the air inlet box, a slope is arranged inside the air inlet box, and limiting grooves are symmetrically arranged at one end of the air inlet box. The dust in the air can be quickly absorbed by the dust collector, at the moment, a first pump machine and a second pump machine are started, water in the water tank is pumped into a flow dividing box and then sprayed out through a spray head, the entering dust is removed, and after the water doped with the dust enters a water tank, the water is filtered through filter cotton in a fixing frame, and then the dust in the water tank is discharged. And dust in water is filtered and screened out, so that the water, located on one side of the filter cotton, in the water tank can be repeatedly used, then the water is pumped into the water tank through the first pump machine, the cyclic utilization effect is achieved, and the
