Abstract
The invention belongs to sulfuric acid solution foamed and cottonseed delinting technology.
There is the foamed acid complex manufacturing technology at present in the cottonseed delinting technology, the raw material costliness, and the alkali neutralization of employing makes seed perishable, and device structure is because the stirring conveying is irregular, and the damage percentage of seedgermination influences the lint quality.Through after a large amount of repetition tests, with cheap industrial chemicals Ninol and OS-15 again with China market on the industrial concentrated sulfuric acid sold make foamed acid, and neutralize with ammonia, improved unreasonable structural device, not only reduce production costs, and improved percentage of seedgermination, guarantee the lint quality.
Description
The invention belongs to sulfuric acid solution foamed and cottonseed delinting technology.
In August, 1980, the U.S. obtained foamed acid delinting of cotton seed technology patent, this technology is because the foamed acid complex manufacturing technology, the raw material costliness, poor to the velveteen penetration, with the alkali neutralization, perishable to seed, it is inhomogeneous that the lint device structure exists stirring to carry, the damage percentage of seedgermination influences the lint quality, causes this patent not obtain fine application.
The objective of the invention is to prepare a kind of inexpensive, make easy, effective foamed acid, the structure that improves equipment guarantees the lint quality.
This lint technology is to utilize the dilute sulfuric acid solution that foams that cottonseed is processed to handle to make its surperficial short flannel carbonization, comes off into the light seed through friction, is convenient to seed selection and mixes the cartridge bag clothing.The foamed acid delinting of cotton seed operation principle is with sulfate foam, after directly mixing by a certain percentage, the industry concentrated sulfuric acid (96-98%) and water is transported to the foamed acid generator of band microporous foam element, feed compressed air generation foamed acid again and enter applicator, quantitative and even is covered in from the gross cottonseed surface that warehouse transports, under the cotton fiber capillarity, soak into cottonseed fluff, moisture content is evaporated in the oven dry of drying machine again, sulfuric acid concentration increases makes the velveteen carbonization, remove the carbonization velveteen and polish the cottonseed surface by rubbing machine and form the light seed, use then in the ammonia and the residual acid on cottonseed surface, treat to carry out the ammonia neutralization again after the cottonseed temperature reduces, reach the safe storage of light seed.
The foamed acid raw material of the present invention's preparation is extensive, and low price is made simple, with producing a kind of fine sulfate of ammoniac chemical fertilizer with residual acid in the ammonia, the secondary amine neutralisation has improved the reliability and the safety that neutralize greatly, and neutralization is good, improved lint equipment, can evenly stir cottonseed, reliable delivery makes foamed acid all evenly be coated on the velveteen, improve the lint effect, guarantee the cottonseed quality.
Fig. 1 warehouse structural representation
Fig. 2 applicator structural representation
Fig. 3 dryer, rubbing machine structural representation
Embodiment of the present invention is the improvement of foamed acid making and lint equipment.
The making of foamed acid is to use separately or mix by proportioning with industrial chemicals Ninol and OS-15, make sulfate foam earlier, adopt the industrial concentrated sulfuric acid (96-98%), sulfuric acid, blowing agent and the water sold on the China market to measure respectively again, in the industrial concentrated sulfuric acid: sulfate foam: water is 10: 0.1-1: the 50-150 ratio directly is mixed and made into foamed acid.
The warehouse architecture advances is seen Fig. 1, has set up two material togglings at an upper portion thereof and has rolled 1, prevents the built on stilts and not equidistant isometrical formula spiral 2 of bottom employing changing from small to big of cottonseed, accomplishes precise metering.
Applicator is seen Fig. 2, stirs conveying axis 3 and adds strong mixing at the cottonseed approach section with curved rod backpitch, and deferent segment further stirs and evenly conveying with forward interruption helical blade, and accomplishes cottonseed is stirred fully with stepless speed regulation, quantitatively carries.
Dryer, rubbing machine cylinder inner wall are arranged with segmentation flight 4 positive interlaces and are seen that Fig. 3 has improved the availability of hot-air like this, the cottonseed conveying is even, clear is convenient, lint is effective.
Claims (3)
1, a kind of band suede cottonseed enters applicator by warehouse and mixes with special foamed acid, forms the light seed by dryer, rubbing machine then, in averager and the technology of stripping fluff from cottonseed with foam acid of residual acid, it is characterized in that the foamed acid preparing process is again:
(1) directly mixes by independent use industrial chemicals Ninol and OS-15 or both and make sulfate foam earlier;
(2) adopt the industrial concentrated sulfuric acid (96-98%), sulfate foam, water to measure respectively, in the industrial concentrated sulfuric acid: sulfate foam: water is that 10: 0.1～1: 50～150 ratios directly are mixed and made into foamed acid.
2, the lint technology according to claim 1 is characterized in that having improved lint equipment:
(1) warehouse top is provided with two material togglings and rolls, and isometrical variable pitch type spiral metering is adopted in the bottom;
(2) the applicator axle is interrupted the helical blade combination with curved rod backpitch and forward, and uses inorganic speed governing;
(3) dryer, rubbing machine cylinder inner wall are arranged with segmentation flight positive interlace.
3, according to claim 1,2 lint technology, it is characterized in that adopting the secondary amine neutralisation.
