Definitions
- the cleaning of lint in the gin is a well known process in fiber preparation. Basically. the process includes snagging the lint upon a saw cylinder and then flaying the lint against mote bars to remove the trash therefrom. After the lint has been beaten against the mote bars, it is doffed from the saw cylinder by doffing brushes.
- the cotton is customarily delivered to the lint cleaning unit as particles of lint located Within an air blast; therefore. it is necessary to condense' the cotton. i.e.. to remove the air from the lint and to form cotton into a batt, after which time the cotton batt is fed to the saw cylinder.
- course screens are used upon the condenser cylinders and at least three sets of directional rollers are used to feed the cotton to the saw cylinder. Also, under present technology. the speed of the saw cylinder compared to the speed of the roller. prior to this time, was traditionally less than to l.
- An object of this invention is to clean lint while keeping air poluti'on at a minimum.
- the cotton first encounters condenser drum 10.
- the cotton lint is fed to the bottom of the drum in an air stream.
- the drum is 50 inches in diameter. 14 feet in length and constructed by conventional techniques. except that it is covered first by an 8 mesh screen (8 wires per inch) and this 8 mesh screen is then covered by the 100 mesh screen 1 100 wires per inch).
- the 8 mesh screen is necessary because the 100 mesh screen is so fine that it lacks the property of being self-supporting unless it is supportd by the courser screen behind it.
- An mesh screen is operable although for ecological reasons at least a mesh is preferred.
- the cotton is fed to the screen in an air stream of about 17.000 cu. ft. per minute and there are 82 sq. ft. of the screen exposed to the air stream. Therefore. the velocity of the air through the screen is about 200 feet per minute or calculated exactly at 207 feet per minute. I have measured the pressure drop across the condenser screen to be 5 lbs. per square foot. At this rate. I have found that I am able to handle about 50 lbs. of cotton per minute. The cotton will have a density on the screen of about 0.017 lb. per square foot.
- the condenser is rotated in the direction as shown in the drawing and then the lint is doffed from the screen by the doffing roller '12,- which is rotated in the direction of the arrow thereon.
- the smoothing roll 14 bears against the condenser roll. I choose to have the main drive to the mechanism through the smoothing roll 14.
- the smoothing roll 14 is a smooth wooden roller 9 inches in diameter and is driven by a variable speed mechanism.
- This mechanism may be either a step pulley or a variable speed electric motor. however. I prefer to use a ⁇ ariable spccd electric motor. It is driven between 40 rpm and 90 rpm.
- the surface speed of all of the equipment has been calculated in feet per minute, assuming that the smoothing roll 14 is driven at 60 rpm. However, it is emphasized that the speeds are only relative and that if the cotton is fed to the condenser at afaster rate. the speed of the smoothing roller will be increased and all of the speeds will be increased, except for the speed of the saw cylinder 16 and its doffing brush- 18. These are driven by a separate drive source and their speed will remain the same regardless of the speed at which the other equipment is being driven.
- smoothing roller 14 will have a surface speed of 141 ft. per minute.
- the chain drive is such that the doffing roll 12 will have a speed of 141 ft. per minute, and the condenser will have a speed of 216 ft. per minute.
- the doffing roller is a 9 in. diameter roll with 20 flights of rubber doffing material.
- the batt Immediately after passing the doffing roller 12 and the smoothing roller 14, the batt is guided or supported by the transfer roller 20 which is a 5 in. smooth aluminum roller driven at a surface speed of 143 ft. per minute. From the transfer roller. the cotton batt passes through the first directional rollers 22 and 24. These directional rollers are 6 in. diameter smooth aluminum rollers and they each have a surface speed of 148 ft. per minute. Immediately after passing through the first directional rollers, the batt passes through the second directional rollers 26 and 28. Roller 26, in this case, is a 4.5 in. splined aluminum roller and the directional roller 28 is a 4.5 in. smooth aluminum roller. The rollers are rotated at a surface speed of 174 ft. per minute.
- the batt After passing through the second directional rollers 26 and 28, the batt is immediately fed to feed roller 30, which is a 4.5 in. splined steel roller having as surface speed 174 ft. per minute. It works against a quarter moon-shaped aluminum feeding plate 32. From there the fatt is fed to the saw cylinder 16 which has a 16 inch diameter and rotates at a surface speed of 4,180 ft. per minute. While the cotton is on the saw cylinder, it is beat against three mote bars 34 as is conventional in cotton cleaning equipment. The cotton is doffed from the saw cylinder by the brush cylinder 18 with hair brushes 18 in. diameter from tip to tip and having a surface speed of 7,500 ft. per minute.
- the spacing between the different rollers and drums is all conventional and, in some cases, the drums are spring biased. E.g., the feed roller 30 and the feed plate 32 are biased toward one another.
- the drive for the equipment is conventional and] prefer to use a chain drive throughout so the relative speed between the different drums is maintained accurately.
- the spacing between the rollers. from one roller to the other and their mounting and housing is all conventional and well understood by those people having ordinary skill in the lint cleaning art.
