Directly pass through with the grains of sand and discharged outside the outlet of screening object, causes greatly to waste；When turning air inlet down, since negative pressure is excessive,
Dust and the grains of sand directly pass through dust conveying fan and are transported to drying duct, can not filter out the grains of sand completely.This sanding dusts
The screening effect of screening plant is poor, contains the grains of sand in the sanding dusts of recycling, when carrying out sanding processing to hair plates, surface is caused to go out
Existing sand grains trace, influences product quality.
Utility model content
The problem to be solved by the utility model is to provide a kind of sanding dusts screening plants, it can solve existing sand
The screening effect of light dust screening plant is poor, contains the grains of sand in the sanding dusts of recycling, when carrying out sanding processing to hair plates, causes
Surface has the problem of sand grains trace.
To solve the above-mentioned problems, the technical solution adopted in the utility model is: this sanding dusts screening plant, including
There are dust spiral conveyer and dust conveying fan, the discharge port of the dust spiral conveyer is connected with screening bellows, described
Screening bellows are connect by pipeline with the dust conveying fan, are equipped with the first screening object in the bottom of the screening bellows and are gone out
Mouthful, the top of the first screening object outlet is equipped with air inlet and air inlet adjustable plate is housed；In the dust spiral conveyer
Discharge outlet dust dispersing device is housed, the screening bellows are provided with spaced muti-piece water conservancy diversion adjusting along the vertical direction
Plate, the lower section of the water conservancy diversion adjustable plate are equipped with multiple second screening object outlets.
In above-mentioned sanding dusts screening plant technical solution, more specific technical solution may also is that the dispersing device
Include it is multiple break up roller, multiple rollers of breaing up are connect by transmission mechanism with engine.
Further, water conservancy diversion adjustable plate described in muti-piece is arranged close at the pipeline, and the water conservancy diversion adjustable plate is by muti-piece V
Shape plate is formed by connecting, and the length direction of the V shaped slab and the flow direction of sanding dusts are substantially vertical, multiple second screenings
Object outlet is located at the bottom position corresponding with the V shaped slab of the screening bellows.
Further, air blower is housed in the top of the air inlet.
Further, the air blower is driven using frequency control motor.
By adopting the above-described technical solution, the utility model has the following beneficial effects: compared with prior art
1, the utility model is equipped with dust dispersing device in the discharge outlet of dust spiral conveyer, and sanding dusts are by beating
In bulk set breaks up to form dispersion dust, in favor of subsequent screening.Screening bellows are provided with spaced more along the vertical direction
Block water conservancy diversion adjustable plate, the lower section of water conservancy diversion adjustable plate are equipped with multiple second screening object outlets, pass through water conservancy diversion adjustable plate and air inlet tune
Section board group, which is closed, to be adjusted to control flow velocity, flow direction and the flow of wind in screening bellows, and muti-piece water conservancy diversion adjustable plate carries out hierarchical screening,
Sand grains and bigger dust particles screen, and screening effect is good, the grains of sand are substantially free of in the sanding dusts of recycling, to hair plates
When carrying out sanding processing, surface is avoided sand grains trace occur, product quality increases substantially.
2, dispersing device include it is multiple break up roller, multiple rollers of breaing up are connect by transmission mechanism with engine；It is multiple to beat
It dissipates the sanding dusts that roller carrys out the transport of dust spiral conveyer to break up, so that sanding dusts is completely formed dispersion dust, more have
Conducive to the grains of sand screening in sanding dusts.
3, muti-piece water conservancy diversion adjustable plate is arranged close at pipeline, and water conservancy diversion adjustable plate is formed by connecting by muti-piece V shaped slab, V shaped slab
Length direction and sanding dusts flow direction it is substantially vertical, it is multiple second screening objects outlet be located at screening bellows bottom with
The corresponding position of V shaped slab.V shaped slab changes flow direction and the flowing velocity of sanding dusts, promotes the grains of sand from sanding dusts
It separates, filters out thinner more grains of sand.
4, air blower is housed in the top of air inlet, air blower is driven using frequency control motor.Air blower can basis
The velocity variations of dust spiral conveyer and adjust the speed automatically, with screening bellows in water conservancy diversion adjustable plate and air inlet adjustable plate it is mutual
Cooperation more effectively controls air quantity and flow velocity in screening bellows, the sand grains in Effective selection dust.
