Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of seed processing machinery, specifically relates to a cotton seed processing device. BACKGROUND

[0002] Cotton seed processing is to remove the residual lint on the surface of cotton seed, so as to facilitate sowing and make the seed sprout more easily.

[0003] At present, the main cotton seed lint removal methods are dry grinding, flame and acid.

[0004] The dry grinding method removes the short lint on the surface of cotton seed through mutual friction between seeds, which has the advantages of simple operation and low cost, but the disadvantage is that the lint removal effect is uneven and the cotton seed is easily damaged.

[0005] The flame method burns the short lint on the surface of cotton seed, which has the advantages of fast lint removal speed and suitability for large-scale production, but the disadvantage is that high temperature may damage the cotton seed and the energy consumption is high.

[0006] The acid method first soaks the cotton seed in acid, then removes the acid on the surface of the cotton seed through a centrifuge, and finally dries the cotton seed using a dryer, which has the advantages of complete lint removal and smooth cotton seed surface, but the disadvantage is that chemical waste liquid needs to be treated, the operation is complex, and the cost is high.

[0007] The applicant provides a cotton seed processing device and a cotton seed lint removal method, which have good lint removal effect, and reduce the consumption of acid and the use amount of activator. SUMMARY

[0012] The horizontal stirring mechanism (6) comprises a horizontal pipe body, a stirring shaft is arranged in the pipe body, an inlet and an outlet are arranged on the pipe body, the inlet is arranged below the discharge port A (13) and can collect the material selected by the air outlet (7), an acid liquid nozzle (10) is arranged on the horizontal stirring mechanism (4), and the acid liquid nozzle (10) adds acid liquid into the pipe body of the horizontal stirring mechanism (4),

[0013] The vertical stirring mechanism comprises a cylinder body, the upper part of the cylinder body is a material inlet, the lower part is provided with a discharge port B (20), the inner wall surface of the cylinder body is provided with a protrusion (1), and the inner cavity of the cylinder body is provided with a stirring brush, the stirring brush comprises a rotating shaft and brush hairs (3) arranged on the surface of the rotating shaft,

[0014] 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 air selection of the air outlet (7), mixed with acid liquid, and then enters the vertical stirring mechanism for sufficient mixing of cotton seeds and acid, and finally is discharged from the discharge port B (20) of the vertical stirring mechanism.

[0015] 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).

[0016] 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.

[0017] The collected full cotton seeds enter the horizontal stirring mechanism (4), the acid liquid is sprayed in the horizontal stirring mechanism (4) to realize mixing of the cotton seeds and the acid liquid, then enter the cylinder body of the vertical stirring mechanism from the outlet of the horizontal stirring mechanism (4), and finally are discharged from the discharge port B (20) at the lower end of the cylinder body to the drying roller for drying.

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 closer, thus achieving cottonseed air separation.

[0025] 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%.

[0026] 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. Attached Figure Description

[0036] The air separation mechanism includes a J-shaped air duct (6), which includes an arc-shaped section (61) and a horizontal section (62). One end of the horizontal section (62) is connected to one end of the arc-shaped section (61), and the other end can be connected to the blower A (63). The arc-shaped section (61) is semi-circular, and the other end of the arc-shaped section (61) is provided with an air outlet (7). The air outlet (7) is located below the discharge port A (13).

[0037] The horizontal stirring mechanism (6) includes a horizontal tube with a stirring shaft inside. The tube has an inlet and an outlet. The inlet is located below the discharge port A (13) and can collect the material separated by the air outlet (7). The horizontal stirring mechanism (4) is equipped with an acid spray nozzle (10) which adds acid to the tube of the horizontal stirring mechanism (4).

[0038] The vertical stirring mechanism includes a cylinder, the upper part of which is a material inlet and the lower part is a discharge port B (20). The inner wall of the cylinder is provided with protrusions (1), and the inner cavity of the cylinder is provided with a stirring brush. The stirring brush includes a rotating shaft and brush bristles (3) disposed on the surface of the rotating shaft.

[0039] After the material is discharged from the outlet A (13) of the material box (8), it is collected by the wind separation of the air outlet (7) into the horizontal stirring mechanism (6), mixed with the acid solution, and then enters the vertical stirring mechanism to fully mix the cottonseed and acid, and finally discharged from the outlet B (20) of the vertical stirring mechanism.

[0040] As an improvement, a drying drum (19) is provided, and the material in the vertical stirring mechanism enters the drying drum (19) through the discharge port B (20).

[0041] In actual use: First, the cottonseed produced by the cotton ginning plant is pre-delinted. The cottonseed with a down content of about 16% is delinted to a down content of 5%-7% by dry grinding. The cottonseed with a down content of 5-7% is stored in the feed hopper. After being discharged from the feed hopper, the plump cottonseed is collected together by the air separation mechanism, and impurities and other useless materials are removed.

[0042] The collected plump cottonseeds enter the horizontal stirring mechanism (4). Acid is sprayed in the horizontal stirring mechanism (4) to mix the cottonseeds and acid. Then, the cottonseeds enter the cylinder of the vertical stirring mechanism from the outlet of the horizontal stirring mechanism (4). The cottonseeds and acid are fully mixed by the interaction of the rotating stirring brush and the protrusions on the inner surface of the cylinder. Finally, the cottonseeds are discharged from the discharge port B (20) at the bottom of the cylinder to the drying drum for drying.

[0046] As an improvement, the rotating shaft of the stirring brush is coaxial with the cylinder.

[0047] As an improvement, the air outlet (7) is a rectangular strip-shaped outlet.

[0048] This utility model has the advantages of simple structure and good performance.

[0049] 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 closer, thus achieving cottonseed air separation.

[0050] 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%.

[0051] 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.

[0052] Example 2: This example discloses a stirring device for cotton seed delinting, which includes a cylinder. The upper part of the cylinder is a material inlet and the lower part is a discharge port B (20). The inner wall of the cylinder is provided with a protrusion (1).

[0054] In this embodiment, the distance between the end of the bristles (3) and the protrusion (1) is between 2mm and 30mm.

[0055] In this embodiment, the rotating shaft of the stirring brush is coaxial with the cylinder.

[0056] In this embodiment, a motor B (21) is provided, which drives the rotating shaft of the stirring brush to rotate.

[0057] 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).

[0058] 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). The cotton seeds and acid are fully mixed through the interaction of the rotating stirring brush and the protrusions on the inner surface of the cylinder. Finally, the seeds are discharged from the discharge port B (20) at the bottom of the cylinder to the drying drum for drying.

[0059] 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.

[0060] Example 3: This example discloses a cotton seed delinting and air separation mechanism, which includes an air duct (6).

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).

[0061] In this embodiment, the horizontal section (62) of the air duct is set horizontally.

[0062] In this embodiment, the air outlet (7) is a rectangular strip-shaped outlet.

[0063] 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).

[0064] 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.

[0065] 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%.

[0066] 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.

[0067] Example 4: This example discloses a cotton seed delinting method, characterized in that: the above-mentioned cotton seed processing device is used, and the specific delinting method is as follows: the cotton seeds are dry-ground to delint, and the cotton seeds with a down content of 5-8% are collected in the material box (8). Then, the cotton seeds are collected in the horizontal stirring mechanism by the air separation mechanism, and acid is added according to the ratio of acid to cotton seed mass of 5-8:100, that is, 5-8 kg of acid is used for 100 kg of cotton seeds. The mixture is initially mixed in the horizontal stirring mechanism, and then fully mixed in the vertical stirring mechanism before being dried in the drying drum.

[0068] The acid used is dilute sulfuric acid.

[0069] The stirring time in the horizontal stirring mechanism is 10s-600s; the stirring time in the vertical stirring mechanism is 10s-600s; and the drying time in the drying drum is 10s-600s.

[0070] 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). The cotton seeds and acid are fully mixed through the interaction of the rotating stirring brush and the protrusions on the inner surface of the cylinder. Finally, the seeds are discharged from the discharge port B (20) at the bottom of the cylinder to the drying drum for drying.

[0071] 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.

[0072] The pre-delinted cottonseeds are discharged from the outlet of the feed box and fall vertically through the air outlet of the air duct.
