[0003] At present, the main cotton seed de-carding methods are dry grinding, flame and acid.
[0004] The dry grinding method removes the short lint on the surface of cotton seeds through mutual friction between the seeds, and has the advantages of simple operation and low cost, but has the disadvantage of uneven de-carding effect and easy damage to the cotton seeds.
[0005] The flame method burns the short lint on the surface of cotton seeds, and has the advantages of fast de-carding speed and suitability for large-scale production, but has the disadvantages of possible damage to the cotton seeds and high energy consumption.
[0006] The acid method first soaks the cotton seeds in acid, then removes the acid on the surface of the cotton seeds through a centrifugal machine, and finally dries the cotton seeds using a dryer, and has the advantages of complete de-carding and smooth surface of the cotton seeds, but has the disadvantages of chemical waste liquid treatment, complex operation and high cost.
[0007] In the acid de-carding method, under the premise of reducing the acid consumption, the same de-carding effect is achieved, the production cost is reduced, the pollution of acid waste liquid is reduced, and the reduction of acid consumption under the premise of meeting the de-carding effect is the goal that the technical personnel constantly explore and pursue.
[0008] The applicant proposes a winnowing device, which can remove the cotton shells and impurities in the pretreated cotton seeds, and screen out the full cotton seeds, and the screened full cotton seeds are subjected to acid treatment, and since the cotton shells and impurities have been removed, the acid consumption is reduced, and the purpose of reducing the acid consumption is achieved.

[0033] As an improvement, a drying roller (19) is arranged, and the material in the vertical stirring mechanism enters the drying roller (19) through the discharge port B (20).
[0034] In actual use, the cotton seeds produced by the ginning factory are first subjected to pre-doffing treatment, the cotton seeds with a down content of about 16% are defatted to cotton seeds with a down content of 5%-7% by dry grinding, and the cotton seeds with a down content of 5%-7% are stored in the material box. After being discharged from the material box, the full cotton seeds are collected together by the air selection mechanism, and the impurities and other useless things are removed.

[0048] In this embodiment, the rotating shaft of the stirring brush is coaxial with the cylinder.
[0049] In this embodiment, a motor B (21) is provided, which drives the rotating shaft of the stirring brush to rotate.
[0050] In this embodiment, a horizontal stirring mechanism (4) is provided. The horizontal stirring mechanism (4) includes a horizontal tube body with a stirring shaft inside. The tube body has an inlet and an outlet. The outlet is connected to the material inlet of the cylinder. The horizontal stirring mechanism (4) is provided with an acid spray nozzle (10). The acid spray nozzle (10) adds acid to the tube body of the horizontal stirring mechanism (4).
[0051] In actual use: the cotton seeds that have undergone preliminary delinting enter the horizontal stirring mechanism (4), and acid is added in the horizontal stirring mechanism (4). The seeds are initially stirred and mixed through the horizontal stirring mechanism (4), and enter the cylinder of the stirring device from the outlet of the horizontal stirring mechanism (4).

[0052] Cottonseed that has undergone preliminary delinting refers to cottonseed with a down content of about 16% that has been delinted to a down content of 5%-7% by dry grinding. That is, this air separation mechanism performs air separation on the dry-ground cottonseed, and the down content obtained by air separation is between 5%-7%. The cottonseed with a down content between 5%-7% is sent into the horizontal stirring mechanism (4) and acid is sprayed to mix the cottonseed and the acid.

[0057] In actual use, the pre-delinted cottonseeds are discharged from the outlet of the feed box and fall vertically through the air outlet of the air duct. Under the action of the air force at the air outlet, the lighter impurities or cotton hulls are blown to a farther distance for collection, while the heavier cottonseeds are collected at a closer distance, thus achieving cottonseed air separation.
[0058] Pre-delinted cottonseed refers to cottonseed with a down content of approximately 16% that has been delinted to 5%-7% through a dry milling process.
