Definitions

  • the present invention relates to a method and a device for reducing the stickiness of the fibers of cotton flakes contaminated with honeydew by the supply of heat.
  • honeydew cotton flakes from some provinces are more or less infested with sugar-containing excretions from insects. These excretions containing sugar are commonly referred to as honeydew.
  • a laboratory method is known by means of which the honeydew is caramelized by heating cotton flake samples in an oven, with the aim of determining the degree of contamination with honeydew from the change in the color of the cotton flake that occurs. This is very important because the cotton flakes become sticky in the event of heavy infestation and tend to stick to different parts of the yarn production system or to form rolls on rollers or other rotatable organs, which is very undesirable since it leads to frequent interruptions in the yarn production process .
  • the object of the present invention is to provide a method and a device of the type mentioned at the outset, which selectively heats the honeydew component of the contaminated flakes with reduced energy expenditure.
  • the flakes in the form of a fleece fleece or a flock of cotton wool are placed on a conveyor belt and a microwave oven constructed as a tunnel is moved therein and heated in the latter by means of microwave energy.
  • the invention provides that the conveyor belt provided for the transport of the cotton flakes through the microwave oven consists of a means that absorbs little energy, in particular of polypropylene, and is deflected by two deflection rollers arranged at the entrance and exit of the tunnel-like oven, one of which can be driven. and that the roof of the housing of the microwave oven is designed as an extractor hood.
  • the present invention is based on the finding that the water molecules contained in sugar or honeydew are preferred in microwave radiation Vibrations are set, whereby a greater heating of the honeydew component takes place in comparison to the remaining components of the flake fleece, whereby the honeydew components are converted into the desired non-tacky state.
  • This selective heating of the honeydew component significantly reduces the amount of energy required for the process compared to other warming-up processes and prevents the temperature of the cotton flakes themselves from becoming too high, so that the risk of fire, which must always be taken into account when treating cotton flakes, is significantly reduced. This also largely avoids the risk of unwanted discoloration of the cotton flakes.
  • the energy supply to the cotton flakes can take place in intermittent operation, ie the conveyor belt stands still in the oven while the fiber flakes placed thereon are heated up.
  • the method is preferably carried out in continuous operation, ie the heating takes place during the movement of the conveyor belt through the tunnel.
  • this has the advantage that the method according to the invention can be optimally integrated into the yarn production, in which a continuous supply of the fiber flakes to the card is desired.
  • the fleece experiences a constant energy density and a correspondingly metered amount of energy in the tunnel due to the continuous movement, so that the honey dew constituents are heated up particularly uniformly, thereby avoiding local heating of the fleece to temperatures that would pose a fire hazard.
  • the leveling out achieved by the movement can also reduce the Energy density in the fleece eliminates any form of wave stirrer.
  • the vapors escaping during the supply of heat in the microwave oven are preferably drawn off during heating, as a result of which the fleece leaves the microwave oven in the dry state.
  • a particularly preferred embodiment of the method according to the invention is characterized in that the fiber flakes remain in the oven for a time in the range from 5 to 30 and in particular for about 20 seconds and with a fleece width in the range from 80 to 120 cm and fleece thickness from 5 to 15 cm, the energy supply in the range of 50-300 kJ per kg of cotton, preferably around 175 kJ per kg of cotton.
  • the values given are with conventional cotton processing equipment and with microwave generators available on the market, e.g. to reach the Gigatherm company.
  • microwave generators with an output power of 1.2 kW each are required, which are preferably arranged in two rows.
  • Control of the energy density can not only be achieved by controlling the output energy of each microwave generator, but it can also be varied within very broad limits by switching off one or more microwave generators. It is also possible to always equip the system with more microwave generators than for the highest degree of Contamination is necessary, so that if one or the other microwave generator fails, a new generator can be put into operation, which can significantly extend the period of use of the microwave oven.
  • the entire oven can be bypassed or put out of operation without this having any adverse effects on the processing of the cotton flakes. E.g. it is not necessary to make any changes to the design of the entire fiber processing system.
  • the microwave oven consists of several microwave generators which can be operated at the same time or individually, these, preferably if there are 10 to 14, in particular 12, microwave generators, are preferably arranged in two rows above the conveyor belt.
  • microwave generators of a width of about 40 cm available on the market to arrange them side by side in two rows such that a nonwoven with a width of about 100 cm can be irradiated uniformly with microwaves.
  • the width of 100 cm mentioned corresponds to the usual fleece width at the outlet of a mixer opener or flake feeder, as a result of which the microwave oven according to the invention can be easily integrated into an existing system.
  • the microwave oven according to the invention or the method according to the invention or the device according to the invention can also be used for ginning.
  • Ferrite rod assemblies arranged at the entrance and exit of the tunnel formed by the microwave oven. These ferrite rods protect the openings at the entrance and exit of the microwave oven, whose housing otherwise consists of continuous metal sheets, against any escape of microwave radiation.
  • shielding plates are preferably arranged on the input and output sides before and after the tunnel formed by the microwave generators, extending transversely to the movement of the fleece and ending immediately in front of its surface.
  • the flake is fed to the conveyor belt through a flake shaft arranged at the input end of the microwave oven with take-off rollers arranged at its lower end.
  • the fleece delivered at the outlet end of the microwave oven is preferably fed to a disintegration unit of a cleaning machine which feeds a flock feeder connected upstream of one or more cards.
  • the fleece can be cooled in a cooling zone operated with cooling air before being fed to the dissolving unit, as a result of which the stickiness of the honey dew is reduced even further.
  • a particularly preferred embodiment of the device according to the invention is characterized in that alarm sensors are arranged inside the housing of the microwave oven and via a control system with a halon gas Fire extinguishing system are coupled. Should a fire arise in the microwave oven from any unforeseeable circumstances, the fire extinguishing system is able to extinguish this fire while switching off the microwave generator. This enables effective fire fighting within the quasi-closed microwave oven.
  • reference numeral 13 denotes the outlet shaft of a combined mixing and cleaning machine 10, e.g. Rieter Unimix B 7/3 or mixer opener B 3/3, which is arranged in front of the microwave oven 11 according to the invention, which is followed by a dissolving unit 12.
  • This disintegration unit can be the disintegration unit of a fine cleaning machine, e.g. of the Rieter ERM cleaner.
  • the first deflecting roller 19 is already arranged shortly after the pair of draw rollers 15, 16 of the combined cleaner 10 and is separated from it by means of a guide plate 22 for the fleece 17.
  • the driven deflection roller 21 is located immediately after the exit of the microwave oven 11 in front of the feed rollers 23, 24 of the opening unit 12, which in the further course of the nonwoven fabric 17 consists of feed rollers 25, 26, a cleaning roller 27 and a grate 28.
  • the fleece 17 obtained from the conveyor belt is dissolved and cleaned by the cleaning roller 27 and the dissolved flakes are then fed into a shaft 29 rising vertically upwards, which leads to a flake feeder (not shown).
  • the microwave oven 11 consists of two rows 30.1, 30.2 of six microwave generators 31 each.
  • the fleece 17 deposited on the conveyor belt which has a width of 1 m and a thickness of approximately 10 cm, is approximately 15 cm below the lower ends of the microwave generators 31, so that the microwaves emitted by these microwave generators have the possibility of being distributed evenly over the width of the fleece. This distribution is started by multiple reflections on the metallic walls 32 of the microwave housing 33 or on a metallic support plate 35 provided below the upper run 34 of the conveyor belt 18 increases.
  • shielding plates 36 are provided which are attached on the input and output sides and extend from the underside of the microwave generator to just above the surface of the fleece 17. Furthermore, around the rectangular inlet 37 and around the rectangular outlet 38 of the microwave oven, respective parallel arrangements of ferrite rods 39, 41 are arranged, which absorb any microwaves that are still present and thus prevent these microwaves from entering the housing of the combined cleaning machine 10 or in this way get to the dissolving unit 12. This keeps the radiation away from the operating personnel.
  • the top of the microwave oven housing 33 is designed as an extractor hood 42, a fan (not shown) extracting the vapors generated by the microwave heating via a nozzle 43 provided at the upper end of the hood 42.
  • Various IR detection sensors 44 are provided within the housing 33 and are connected to a control system. If local overheating occurs during operation, the system, especially the microwave generator 31, is switched off via the control system and a halon extinguishing gas is introduced into the housing via the nozzles 45, which displaces oxygen and prevents a fire or an emerging fire is extinguished immediately.
  • the heat supply can be easily adjusted to the moisture content of the cotton and the honeydew contamination.
  • the microwave devices themselves work with a 12 cm wavelength at a frequency of 2.45 gigahertz.
  • the energy supply to the fleece should be dimensioned such that, taking into account the throughput speed of the conveyor belt, the honeydew deposits are warmed up to approximately 140 ° C., which is sufficient to extract approximately 80% of the water contained therein and the deposits in a readily processable, non-sticky state to convict.
  • deflectors 46 which can be controlled within the microwave oven housing for controlling the microwaves, such deflectors 46 being shown in FIG. 2 between the adjacent rows 30.1, 30.2 by microwave generators. These deflectors can be controlled in such a way that a uniform energy distribution over the entire width of the fleece is obtained without the radiation obtained in the middle of the fleece from the two neighboring microwave generators leading to local overheating of the fleece or the honeydew deposits there.
  • This Ab Wise are normally set once and for all in the manufacture of the microwave oven, taking into account the properties of the microwave generators installed there.
  • FIG. 3 shows a variant of the device of FIG. 1 in that a cooling zone 70 is provided between the deflection roller 21 of the conveyor belt 18 and the feed rollers 23 and 24 in order to cool the heated fiber wadding between two cooling conveyor belts 71 and 72.
  • the cooling zone 70 is covered by a suction hood 73, on which a connecting piece 74 is provided.
  • This connection piece 74 is connected to a suction fan (not shown) in order to generate the air flow L through the cooling conveyor belts 71 and 72.
  • Air inlet openings are provided in the walls which surround the cooling zone and the dissolving unit 12, to which the feed rollers 23 and 24 belong, in order to allow the aforementioned air flow L and the air for the shaft 29 to flow in.
  • an air conditioning device (not shown) can be connected upstream of the aforementioned air inlet openings.
  • the conveyor belts 71 and 72 are driven synchronously by a single drive (not shown) and convey the fiber wadding on the conveyor belt 18 at the output speed of the fiber wadding.
  • the shaft 29 has a cross section and a length which enables cooling during the conveyance.
  • the air speed in the shaft 29 will be slightly above the floating speed of the fiber flakes in order to allow a sufficient dwell time without too great a height of the shaft.
  • conditioning the air sucked into the shaft 29 beforehand is also possible.
