The first air suction pipe 630 is used for sucking out impurities inside the ash bucket 742, and the second air suction pipe 640 is used for sucking out floating objects inside the first trash removal chamber 200 and the second trash removal chamber 300.

One side of the bellows 610 is provided with a box door 611, the filter plate 612 is arranged on the inner side, the suction fan 620 is positioned on one side of the filter plate 612, the first suction pipeline 630 and the second suction pipeline 640 are positioned on the other side, and after the box door 611 is opened, the impurities and the filter screen 741 inside can be cleaned. At intervals, the bellows 610 is opened to clean the interior of the housing of the trash.

A bulk hopper 150 and a collection hopper 160 are provided under the second partition 140.

The bulk hopper 150 is connected to the stirring shaft 410, and the bulk hopper 150 is formed in a conical shape, and has a smaller cross-sectional area at one end close to the second partition plate 140 and a larger cross-sectional area at the end far away from the second partition plate 140.

The collecting hopper 160 is fixed on the box body 100, the vertical section of the collecting hopper 160 is W-shaped, and the middle part of the collecting hopper is provided with a second shaft hole 161 for the stirring shaft 410 to pass through; the material collecting hopper 160 forms a concave material collecting groove 162 in the middle; a material collecting opening 163 is formed in the bottom of the material collecting groove 162, and a material discharging pipeline 170 is connected between the material collecting opening 163 and the material discharging opening 120. The raw material dropped from the second feed port 141 can be guided to the inside of the collecting hopper 160 by the bulk hopper 150.

Be provided with fixedly on (mixing) shaft 410 and scrape flitch 180, scrape flitch 180 butt inside silo 162 that the rotatory in-process of (mixing) shaft 410 drives and scrapes flitch 180 and rotate, rotates the in-process, scrapes the raw materials in the collecting hopper 160 into in the mouth 163 that gathers materials, and then carries out through ejection of compact pipeline 170.

When the dust removing device is used, firstly, raw materials to be screened are added into the feeding hopper 710, after the raw materials in the feeding hopper 710 enter the feeding bin 700, the feeding motor 722 works to drive the rotating shaft 721 to rotate, and then the auger blade 723 is driven to rotate, the materials are conveyed in the rotating process, the materials are synchronously stirred in the conveying process, so that dust and small-diameter impurities in the materials fall into the dust collecting hopper 742, and then the impurities are sucked into the air box 610 through the first air suction pipeline 630, so that the dust removing work is completed. The raw materials after the dust removal get into first edulcoration cavity 200 through feed inlet 110 and tentatively get rid of the floater in, in this process, last the air-blast through air-blower 520, there is certain amount of wind in first edulcoration cavity 200, and then can blow up the easy floated impurity in the raw materials, later get into bellows 610 inside through second air suction pipeline 640, raw materials after the preliminary edulcoration are under puddler 420's stirring effect, continuously get into in second edulcoration cavity 300 by first feed opening 131, get into the inside raw materials of second edulcoration cavity 300, under the effect of air-blast mechanism 500 and second air suction pipeline 640, wherein remaining floater screening breaks away from the raw materials. The screened raw material passes through the second feed opening 141, the bulk hopper 150, and the collecting hopper 160 and is discharged.

The invention provides a raw material impurity removing and screening device for grain and oil processing, which can remove impurities of raw materials passing through a first impurity removing cavity 200 and a second impurity removing cavity 300 in sequence and screen floaters mixed with the raw materials by an air blowing mechanism 500 and an air suction mechanism 600. Because the screening is carried out in the closed container, the influence of floaters on the air environment is avoided. Simultaneously, in the screening process, the raw materials in first edulcoration cavity 200 is stirred through the rabbling mechanism 400 that sets up, and is first, play the stirring effect, and the stirring in-process for the raw materials separates more thoroughly with the floater, and the second plays the purpose of unloading, pushes away the raw materials on first baffle 130 to first feed opening 131 in. Simultaneously, because first feed opening 131 is located first baffle 130, play the effect of keeping out the wind through the raw materials, can avoid in the floater gets into second edulcoration cavity 300 in step, and then, inside second edulcoration cavity 300, the floater is less relatively, after the inside further screening floater of second edulcoration cavity 300, floater impurity is less in the raw materials. The screening effect is better.
