Furthermore, a water drain pipe is installed at the bottom of the dust removal air duct, an electric gate valve is installed on the water drain pipe, a water level sensor is further installed at an inlet of the water drain pipe, the water level sensor is electrically connected with a controller, and the controller is electrically connected with the electric gate valve.

The utility model has the advantages that: the utility model discloses simple structure installs the dust removal dryer on dust exhausting fan's dryer to design a plurality of groups shower nozzles in the dust removal dryer, meanwhile at the terminal installation dust removal net of dust removal dryer, form dual dust catching, the effectual dust collection efficiency that has improved designs intelligent drainage equipment simultaneously, makes the timely discharge of dust removal water, has improved the degree of automation of equipment, is worth using widely on a large scale.

Description of the drawings:

FIG. 1 is a schematic view of the usage state of the present invention;

fig. 2 is a perspective view of the present invention;

FIG. 3 is an enlarged view of part A of FIG. 2;

FIG. 4 is a view of the control element mounting of the present invention;

fig. 5 is a side view of the present invention;

in the figure, a driving roadway 1, a dust removal fan 2, a dust removal air duct 3, a dust removal net 4, a sliding column 5, a sliding block 6, a sliding groove 7, a limiting block 8, a water spraying ring pipe 9, a water spraying straight pipe 10, a spray head 11, a water inlet main pipe 12, a water discharge pipe 13, an electric gate valve 14, a water level sensor 15 and a controller 16.

The specific implementation mode is as follows:

as shown in fig. 1 to 5, a dust collecting device of a dust removing fan for driving a roadway comprises a dust removing fan 2 installed in a driving roadway 1, a wind barrel of the dust removing fan 2 is connected with a dust removing wind barrel 3, a circular dust removing net 4 is arranged at the other end of the dust removing wind barrel 3, a plurality of sliding columns 5 are horizontally and fixedly connected with the outer edge of the dust removing net 4, a sliding block 6 is fixedly installed at the other end of the sliding column 5, a plurality of sliding grooves 7 matched with the sliding block 6 are arranged on the outer circumferential surface of the dust removing wind barrel 3, the sliding block 6 is in sliding connection with the sliding grooves 7, a limiting block 8 is further arranged on the sliding grooves 7, the limiting block 8 is fixedly connected with the sliding grooves 7 through bolts, an annular water spray 9 is further sleeved on the dust removing wind barrel 3, a plurality of water spray straight pipes 10 are horizontally and uniformly distributed along the circumferential direction on the water spray annular pipe 9, a spray head 11 is arranged on the water spray straight pipe 10 in a radial inward mode, the spray head 11 penetrates through the wall thickness of the dust removal air duct 3, the water spray ring pipe 9 is communicated with a water inlet main pipe 12 in an outward mode, and a water valve is arranged on the water inlet main pipe 12; a water discharge pipe 13 is installed at the bottom of the dust removing air duct 3, an electric gate valve 14 is installed on the water discharge pipe 13, a water level sensor 15 is also installed at an inlet of the water discharge pipe 13, the water level sensor 15 is electrically connected with a controller 16, and the controller 16 is electrically connected with the electric gate valve 14.
