[0031] After the material is discharged from the discharge port A (13) of the material box (8), the material is collected into the horizontal stirring mechanism (6) by the air force of the air outlet (7), mixed with the acid liquid, and then enters the vertical stirring mechanism to be fully mixed with the acid, and finally is discharged from the discharge port B (20) of the vertical stirring mechanism.

[0032] As an improvement, a drying roller (19) is provided, and the material in the vertical stirring mechanism enters the drying roller (19) through the discharge port B (20).

[0033] In actual use, the cotton seeds produced by the ginning factory are first subjected to pre-doffing treatment, and 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.

[0034] The collected full cotton seeds enter the horizontal stirring mechanism (4), and the acid liquid is sprayed in the horizontal stirring mechanism (4) to realize the mixing of the cotton seeds and the acid liquid, and then enters the cylinder of the vertical stirring mechanism from the outlet of the horizontal stirring mechanism (4), and then is fully mixed with the acid through the rotation of the stirring brush and the interaction of the protrusions on the inner surface of the cylinder, and finally is discharged from the discharge port B (20) at the lower end of the cylinder to the drying roller for drying.

[0039] As an improvement, the air outlet (7) is a rectangular strip-shaped opening.

[0040] The utility model has the advantages of simple structure, good use effect and the like.

[0041] The cotton seeds subjected to pre-doffing are discharged from the discharge port of the material box, vertically fall, pass through the air outlet of the air duct, and are blown to a far place by the air force of the air outlet to realize the collection of the relatively heavy cotton seeds, so that the cotton seeds are air selected.

[0042] The pre-doffed cotton seed refers to the cotton seed with a lint content of about 16% after being defibred by dry milling to a lint content of 5-7%. That is, the wind selection mechanism is used to perform wind selection on the dry-milled cotton seed, and the wind selection is performed to obtain a lint content of 5-7%.

[0043] Due to the fact that the front part of the air outlet of the air duct is provided with a semicircular arc-shaped track, the air flow changes when passing through the horizontal section of the air duct and entering the arc-shaped section, and finally the air flow out of the air outlet has different flow rates at different horizontal layers, so that better wind selection effect is achieved.

[0044] In this embodiment, the brush (3) is one of a nylon brush, a steel brush and an iron brush.

[0045] In this embodiment, the brush (3) is one of a nylon brush, a steel brush and an iron brush.

[0046] In this embodiment, the distance between the end of the brush (3) and the protrusion (1) is 2-30 mm.

[0047] In this embodiment, the shaft of the stirring brush is coaxially arranged with the cylinder.

[0048] In this embodiment, a motor B (21) is arranged, which drives the shaft of the stirring brush to rotate.

[0049] In this embodiment, a horizontal stirring mechanism (4) is arranged, which comprises a horizontal pipe body, a stirring shaft arranged in the pipe body, an inlet and an outlet arranged on the pipe body, the outlet being connected to the material inlet of the cylinder, and an acid liquid nozzle (10) arranged on the horizontal stirring mechanism (4) and adding acid liquid into the pipe body of the horizontal stirring mechanism (4).

[0050] In actual use, the cotton seed after preliminary defibering is fed into the horizontal stirring mechanism (4), and acid is added in the horizontal stirring mechanism (4), and the cotton seed is preliminarily stirred and mixed in the horizontal stirring mechanism (4), and then is fed into the cylinder of the stirring device from the outlet of the horizontal stirring mechanism (4), and finally is discharged from the discharge port B (20) at the lower end of the cylinder to the drying drum for drying.

[0051] 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.

[0052] Example 3: This example discloses a cotton seed delinting and air separation mechanism, which includes an air duct (6). The air duct (6) is "J" shaped, that is, the air duct (6) includes an arc section (61) and a horizontal section (62). One end of the horizontal section (62) is connected to one end of the arc section (61), and the other end can be connected to a fan A (63). The arc section (61) is a semi-circular ring. The other end of the arc section (61) is provided with an air outlet (7). The air outlet (7) is parallel to the air horizontal section (62).

[0053] In this embodiment, the horizontal section (62) of the air duct is set horizontally.

[0054] In this embodiment, the air outlet (7) is a rectangular strip-shaped outlet.

[0055] In this embodiment, a material box (8) is also provided. The material box is provided with a discharge port A (13). The discharge port A (13) is located above the air outlet (7). After the material in the material box (8) is discharged from the discharge port A (13), it can be air-separated by the wind force of the air outlet (7).

[0056] 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.

[0057] 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. In other words, this air-separation mechanism performs air separation on the dry-milled cottonseed, resulting in a down content between 5% and 7%.

[0058] Because the air outlet of the air duct has a semi-circular arc track at the front, the airflow changes when it enters the arc section after passing through the horizontal section of the air duct. As a result, the airflow velocity at different horizontal levels is different when it exits the air outlet, thus achieving a better air separation effect.

[0059] Embodiment 4: The embodiment discloses a cotton seed de-fuzzing method, characterized by using the cotton seed processing device, and the specific de-fuzzing method is as follows: cotton seeds are subjected to dry grinding de-fuzzing treatment, and cotton seeds with a floss content of 5-8% are collected into the material box (8), then the cotton seeds are subjected to air separation by the air separation mechanism, the cotton seeds are collected in the horizontal stirring mechanism, and acid is added according to a mass ratio of 5-8:100, that is, 5-8 kg of acid is added to 100 kg of cotton seeds, the cotton seeds are preliminarily mixed in the horizontal stirring mechanism, and the cotton seeds are fully mixed in the vertical stirring mechanism, and then the cotton seeds are dried in the drying roller.

[0060] The acid is dilute sulfuric acid.

[0061] The stirring time of the horizontal stirring mechanism is 10s-600s, the stirring time of the vertical stirring mechanism is 10s-600s, and the drying time in the drying roller is 10s-600s.

[0062] In actual use, the cotton seeds subjected to preliminary de-fuzzing enter the horizontal stirring mechanism (4), acid is added in the horizontal stirring mechanism (4), the cotton seeds are preliminarily stirred and mixed in the horizontal stirring mechanism (4), the cotton seeds are discharged from the outlet of the horizontal stirring mechanism (4) into the cylinder of the stirring device, the cotton seeds are fully mixed with the acid under the interaction of the rotation of the stirring brush and the protrusions on the inner surface of the cylinder, and finally the cotton seeds are discharged from the discharge port B (20) at the lower end of the cylinder to the drying roller for drying.

[0063] The cotton seeds subjected to preliminary de-fuzzing refer to cotton seeds with a floss content of 5%-7% obtained by dry grinding de-fuzzing of cotton seeds with a floss content of about 16%. That is, the air separation mechanism is used to air separate the cotton seeds after dry grinding, and the cotton seeds with a floss content of 5%-7% are obtained.

[0064] The cotton seeds subjected to preliminary de-fuzzing are discharged from the discharge port of the material box, vertically fall, pass through the air outlet of the air duct, and are blown to a far place for hand collection under the action of the air flow of the air outlet, and the heavier cotton seeds are collected at a close place, so that the cotton seeds are air separated.

[0065] The cotton seeds subjected to preliminary de-fuzzing refer to cotton seeds with a floss content of 5%-7% obtained by dry grinding de-fuzzing of cotton seeds with a floss content of about 16%.

[0066] Since the front part of the air outlet of the air duct is provided with a semicircular arc-shaped track, the air flow changes when passing through the horizontal section of the air duct and entering the arc-shaped section, and the air flow out of the air outlet has different flow rates at different horizontal layers, so that better air separation effect is achieved.
