Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of seed processing machinery, and in particular relates to a cotton seed processing device. Background Art
[0002] Cotton seed processing is the process of removing the residual lint on the surface of cotton seeds to facilitate sowing and make the seeds easier to germinate.
[0003] The main methods for delinting cottonseed are dry grinding delinting, flame delinting and acid delinting.
[0004] Dry grinding delinting is a method of removing the short lint on the surface of cotton seeds by rubbing the seeds against each other. Its advantages are simple operation and low cost, but its disadvantages are uneven delinting effect and easy damage to cotton seeds.
[0005] Flame delinting uses flame combustion to burn off the short lint on the surface of cotton seeds. Its advantages are fast delinting speed and suitability for large-scale production, but its disadvantages are that high temperature may damage cotton seeds and high energy consumption.
[0006] The acid delinting method is to soak the cotton seeds in acid solution first, then use a centrifuge to remove the acid on the surface of the cotton seeds, and finally use a dryer to dry the cotton seeds. Its advantages are thorough delinting and a smooth surface of the cotton seeds, but its disadvantages are that it requires the treatment of chemical waste liquid, complicated operation and high cost.
[0007] The applicant has proposed a cotton seed processing device and a cotton seed delinting method with good delinting effect and reduced acid consumption and activator usage. Summary of the invention

The horizontal stirring mechanism (6) comprises a horizontal tube body, a stirring shaft is arranged in the tube body, an inlet and an outlet are arranged on the tube body, the inlet is arranged below the discharge port A (13), and the inlet can collect the material selected by the air outlet (7), the horizontal stirring mechanism (4) is provided with an acid liquid spray head (10), and the acid liquid spray head (10) adds acid liquid into the tube body of the horizontal stirring mechanism (4), The vertical stirring mechanism comprises a cylinder, the upper part of the cylinder is a material inlet, the lower part is provided with a material outlet B (20), the surface of the inner wall of the cylinder is provided with a protrusion (1), the inner cavity of the cylinder is provided with a stirring brush, and the stirring brush comprises a rotating shaft and bristles (3) arranged on the surface of the rotating shaft. After the material is discharged from the discharge port A (13) of the material box (8), it is collected into the horizontal stirring mechanism (6) through the wind selection of the air outlet (7), mixed with the acid solution, and then enters the vertical stirring mechanism to fully mix the cottonseed and the acid, and finally discharged from the discharge port B (20) of the vertical stirring mechanism.
[0010] As an improvement, a drying drum (19) is provided, and the material in the vertical stirring mechanism enters the drying drum (19) through a discharge port B (20).
[0011] In actual use: first pre-delint the cotton seeds produced by the cotton ginning mill, and use the dry grinding method to delint the cotton seeds with a down content of about 16% to 5%-7%, and store the cotton seeds with a down content of 5-7% in a material box. After being discharged from the material box, the full cotton seeds are collected together through the air separation mechanism, and impurities and other useless materials are removed.
[0012] The collected full cotton seeds enter the horizontal stirring mechanism (4), where acid liquid is sprayed to mix the cotton seeds and the acid liquid. The cotton seeds then enter the cylinder of the vertical stirring mechanism from the outlet of the horizontal stirring mechanism (4), where they are then fully mixed with the acid through the interaction of the rotation of the stirring brush and the protrusions on the inner surface of the cylinder. The cotton seeds are finally discharged from the discharge port B (20) at the lower end of the cylinder to the drying drum for drying.
[0013] As an improvement, the air outlet direction of the air outlet (7) is parallel to the horizontal section (62) of the air duct, and the horizontal section (62) of the air duct is arranged horizontally.

[0018] The invention has the advantages of simple structure, good use effect and the like.
[0019] The pre-delinted cotton seeds are discharged from the discharge port of the material box, and pass through the air outlet of the air duct after vertically falling. Under the action of the wind force from the air outlet, the lighter impurities or cotton shells are blown to a farther place for mobile phone collection, and the heavier cotton seeds are collected at a closer place, finally realizing the cotton seed winnowing.
[0020] Pre-delinted cotton seeds refer to cotton seeds with a lint content of about 16% that have been delinted to a lint content of 5%-7% by dry grinding. That is, this air separation mechanism air separates the dry-grinded cotton seeds, and the lint content obtained by air separation is between 5% and 7%.
[0021] Since a semicircular arc track is provided in front of the air outlet of the air duct, the airflow will change when it passes through the horizontal section of the air duct and enters the arc section. Finally, the airflow out of the air outlet has different flow rates in different horizontal layers, achieving a better air selection effect.
[0022] The present invention also discloses a cotton seed delinting method, which is characterized in that: using the above-mentioned cotton seed processing device, the specific delinting method is as follows: dry grinding and delinting the cotton seeds to obtain cotton seeds with a lint content of 5-8% and collect them in a material box (8), then air-selecting them through an air-selecting mechanism, collecting the cotton seeds in a horizontal stirring mechanism, and adding acid according to a mass ratio of acid to cotton seeds of 5-8:100, that is, using 5-8 kg of acid for 100 kg of cotton seeds, preliminarily mixing them in the horizontal stirring mechanism, fully mixing them in the vertical stirring mechanism, and then drying them in a drying drum.
[0023] The acid is dilute sulfuric acid.
[0024] 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.
[0025] In actual use, the cotton seeds that have undergone preliminary delinting enter the horizontal stirring mechanism (4), acid is added to the horizontal stirring mechanism (4), and preliminary stirring and mixing is performed through the horizontal stirring mechanism (4). The cotton seeds enter the cylinder of the stirring device from the outlet of the horizontal stirring mechanism (4), and then the cotton seeds and the acid are fully mixed through the interaction of the rotation of the stirring brush and the protrusions on the inner surface of the cylinder. Finally, the cotton seeds are discharged from the discharge port B (20) at the lower end of the cylinder to the drying drum for drying.
[0026] The preliminarily delinted cotton seeds refer to cotton seeds with a lint content of about 16% that have been delinted to a lint content of 5%-7% by dry grinding. That is, the cotton seeds stored in the material box have a lint content of 5%-7%. After being discharged from the material box, the full cotton seeds are collected together by the air selection mechanism, that is, the cotton seeds entering the horizontal stirring mechanism are all full cotton seeds, and the lint content of the cotton seeds is between 5%-7%. Acid is sprayed in the horizontal stirring mechanism (4) to achieve mixing of the cotton seeds and the acid.
[0027] The winnowing process is as follows: the pre-delinted cotton seeds are discharged from the discharge port of the material box, and after vertically falling, they pass through the air outlet of the air duct. Under the action of the wind force at the air outlet, the lighter impurities or cotton shells are blown to a farther place for mobile phone collection, and the heavier cotton seeds are collected at a closer place, finally realizing the winnowing of cotton seeds.
[0028] Since a semicircular arc track is provided in front of the air outlet of the air duct, the airflow will change when it passes through the horizontal section of the air duct and enters the arc section. Finally, the airflow out of the air outlet has different flow rates in different horizontal layers, achieving a better air selection effect. BRIEF DESCRIPTION OF THE DRAWINGS
