Definitions

  • the invention relates to a device for separating the cotton waste from a conventional cotton cleaning machine into good fibers and dirt. Disposals are incurred when extracting cotton and cleaning cotton in the spinning mill. The exits contain a high percentage of spinnable good fibers, which are mostly lost but are to be recovered for the spinning mill.
  • the machine is known which is of simple construction and causes the outlets to be separated into good fibers and dirt.
  • the machine is known under the name Shirley device.
  • the task of the Shirley device is to completely separate the good fibers from the dirt, as is necessary for testing purposes.
  • the Shirley device consists of a feed device and an opening roller that carries the licker-in set. The separating effect is achieved by centrifugal force and a special air flow. The material accumulating at the separation points is repeatedly presented to the feed device for complete separation; this continues until complete separation is achieved.
  • DE-B-1 202195 shows a machine for opening and cleaning or mixing fiber material, in particular cotton and wool waste. It is a step opener and a shaft located in front of its inlet, the bottom of which is designed as a flap which is opened in each case when the shaft contains a predetermined amount of fiber material.
  • the outlet of the step opener is connected on the one hand via a pipe with a condenser feeding the shaft to a circuit into which the inlet of the fiber material opens, and on the other hand connected to an output line, one of one for an alternative connection to the condenser and the output line Switchgear controlled flap is provided. By appropriately controlling this flap, the fiber material runs through the step opener until a very uniform mixture is achieved, after which it is conveyed away via the tube mentioned.
  • GB-A-884245 shows a carding machine in which the drum roll, viewed in the direction of rotation, is cleaned behind the take-up roll by an axially reciprocating suction nozzle of a blower, the material removed in this way being removed by a nozzle in the area between the feed trough and a preliminary roll Carding process is fed again.
  • the long fibers that can still be used are to be reintroduced into the process, while the fibers and impurities that are too short are to be eliminated.
  • the exits that accumulate however, still have a considerable proportion of usable fibers, which is economically desirable to recover.
  • the invention is therefore based on the object of specifying a device which separates the exits from cotton processing processes in a particularly efficient manner into good fibers and dirt, which is to be achieved economically by providing a device which is matched in its throughput to the respective cotton processing process and which in Neighborhood to this main process can be operated, the resulting good fibers are reintroduced into the haptic process.
  • the separating device is provided with a plurality of dressing rollers which are connected to one another and which are used in the carding position with respect to one another and to which separating points for different fractions are assigned, the separating points for controlling the material flow in the separating device being designed so as to be lockable , and that the clothing rollers rotate in the same direction of rotation and produce an increasingly strong centrifugal force effect, d. H. have increasing peripheral speed and / or decreasing diameter.
  • the outlets are fed in portions to a separating device via a feed device and broken down into different fractions.
  • the Fractions contain different concentrations of good fibers and dirt compared to the exits presented.
  • Each fraction is collected separately and after passing through at least one portion in fractions it is again presented to the separating device.
  • the separating device is reversed, ie each fraction undergoes processing in accordance with its character. It was found that typical material consistencies always occur at the separation points of the individual fractions, which are then specifically processed further.
  • the special further treatment can be achieved by operating the separating elements at different speeds. It is also possible to temporarily close certain separating points and thereby bridge them, so that the material takes a different route internally through the separating elements. It is also possible to feed the material to other separators bypassing upstream separators. The material passes through the separator internally until it is economically separated. That doesn't have to be the maximum possible separation.
  • the good fibers which accumulate with a specific degree of purity at certain separation points, can be fed continuously to the main process, but it is also possible for them to pass through the separation device repeatedly.
  • the waste that remains in the end is excreted.
  • a modified embodiment of the device provides that the fractions returned to the feed device are subjected to screening.
  • the loose dirt particles are separated and no longer burden the process or the actual device. Air jet sieves and cyclones have proven to be particularly suitable for this. It has also been shown that the still coarse fraction obtained at the first separation point is advantageously continuously recycled.
  • the loose dirt is sieved off and the rest of the fraction is passed on to the feed device.
  • the device consists of a feeding device, a separating device with lockable separating points, the storage points assigned to the separating points for receiving the (differently cleaned) fractions and an internal transport device for returning the material to the feeding device, for removing the waste and for transporting the good fibers into the main process .
  • the internal transport is preferably carried out pneumatically.
  • a metering device which is effective for all stores is arranged. Its task is to dissolve the amorphous (contiguous) storage content in flakes that can be transported in the air flow.
  • a pin roller meets the requirements.
  • auxiliary air can be mixed in through a special opening, thereby stabilizing the flow of flakes in the air flow.
  • the feed device has feed means which allow a sequential feed of the separation device with the individual fractions without mixing beforehand.
  • the same purpose can be achieved by arranging several parallel filling chutes that work alternately on a feed roller.
  • Further feed rollers can be arranged for the purpose of the environment of separating elements.
  • the separating members of the separating device consist of clothing rollers of known type. Several rollers can be arranged which are in the removal or carding position with respect to one another. The number of tips and the peripheral speed of the rollers expediently increase, the diameters decreasing.
  • the scraper rollers have separating points of a known type. They are designed so that they can be closed, so that in connection with an internal transport device different material guides can result or be realized by the device.
  • the fiber guiding surfaces of the separating members can also carry garnishes.
  • a garnish can be arranged on the first separating member between the feed roller and the first separating point, which is not, as usual, in the carding position for garnishing the separating member.
  • the material is dedusted together with ventilation openings that alternate between blowing and suction air.
  • the garnish acts as an intensive swirl field that loosens the dust. The special orientation of the tips prevents the garnish from filling and, unlike the dust particles, the fibers are prevented from following the air flow.
  • an opening device is used in addition to a metering device. This causes an intensive mixing of the outlets and the transport air.
  • the opening device is close to the inlet connection. It consists of garnished, rapidly rotating rollers. The axes of rotation of the garnished rollers are advantageously parallel to the axis of rotation of the vortex in the cyclone. The removal of the material is facilitated by streamlined baffles, with additional auxiliary air being supplied.
  • the device can have a programmable controller.
  • the program contains all the information necessary to implement a portion or a work cycle with all material runs, speeds of the separating elements and various possible ways. Programming is based on experience. Because of the great possibilities in the implementation of the method, the device can be converted without ver by simply reversing to ver different outlet types can be set. A more complete design of the device provides for the installation of sensors which react to relevant parameters of outlets or their fractions. Together with a process control system of known type, the device can adjust itself to an optimal mode of operation.
  • the main process 1, i. H. outlet 2 originating from a conventional cotton cleaning machine is fed to a feed device 3.
  • the feeding device 3 feeds the separating device 4.
  • the separating device 4 here consists of three separating members 41, 42 and 43, which have four separating points 51, 52, 53 and 54, three of which are closable. As a result, the material flow in the separating device 4 can be controlled differently.
  • the separating points 51, 52 and 53 are assigned memories 61, 62 and 63. They take up the resulting fractions and deliver them to an internal transport system 7.
  • the internal transport system 7 includes a metering device 71, which produces flakes from an amorphous (connected) fraction 81, 82, 83. The flakes can be transported pneumatically to the feed device 3, for example.
  • the feed device 3 has parallel filling shafts 31, 32 and 33, into which the individual fractions are fed to a feed roller without intermixing.
  • the fractions 81, 82 and 83 occurring at the separation points 5 pass through the separation device 4 in different ways and with different, ie. H. Working speeds of the separating members 41, 42 and 43 matched to the respective fraction.
  • the good fibers 9 are returned to the main working process 1, while after a certain number of runs the exploited waste 10 is separated out. This is continued in portions.
  • FIG. 2 A modification of the device is shown in FIG. 2.
  • a screening device is inserted within the internal transport system 7. It has been shown that in the first fraction 81 many loose, i.e. H. Debris that is not related to fibers is contained and can be removed immediately. This relieves the separation device 4. A fraction can be continuously screened and fed back. It is also possible for all fractions 81, 82 and 83 to be screened and fed back in succession.
  • a known cyclone 101 is used here as the screening device, which has an additional opening device 102 from its inlet connection. It creates an intensive mixture of material and air, whereby the flakes are broken down down to their individual components. The sufficiently large amount of air required for this is supplied by auxiliary air ducts 104, which open both at the opening device 102 and at the metering device 71. At the same time, they make it easier to deliver materials to these workplaces.
  • the cyclone 101 is followed by the feed device 3.
  • the device according to FIG. 1 can be expanded to include the devices from FIG. 2 if necessary.
  • FIG. 3 a simple embodiment of a device according to the invention is shown semi-schematically.
  • Interconnecting clothing rollers 411, 422 and 433 are used here as separating elements. They have lockable separation points 511, 522 and 533.
  • the clothing rollers 411, 422 and 433 are used in carding position with respect to each other. They have an increasing number of peaks and a gradually increasing centrifugal force effect, i. H. that the centrifugal force on the clothing rollers should increase from left to right.
  • the material can be removed, for example, by suction air and by blowing air, as well as by a take-off roller 554 shown here, which works together with a knock-off roller 555.
  • Pickup roller and chopper roller 555 are quiet and energy-saving.
  • FIG. 4 shows a specially designed fiber guide surface 600, as is used in particular behind a feed roller 300.
  • the roller 300 in FIG. 4 corresponds to the roller over the clothing roller 411 in FIG. 3. 4 serves to generate an intense friction and vortex field.
  • the tips 601 are not in carding position to the tips of the clothing roller 411.
  • Blown air guides 603 and suction air guides 604 open in alternating sequence between the tips 601. Filter outlets with a high dust content, for example, can be dedusted in this way.
  • the fibrous components cannot follow the suction air flow 604 due to the special orientation of the tips 601 of the garnish.
  • the suction air guides are opposite to the direction of movement predetermined by the centrifugal force.
