Definitions

  • the present invention relates to a continuous process or device for reducing the stickiness of the fibers of cotton fibers contaminated with honeydew by heating with microwave energy, thereby converting the honeydew into a substantially non-sticky substance.
  • honeydew cotton flakes from some provenances 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, in the event of heavy infestation, the cotton flakes become sticky and tend to stick to different parts of the yarn production system or 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 up the honeydew component of the contaminated flakes by means of microwave energy with reduced energy expenditure.
  • the flakes are pressed into a flake fleece or a flake wadding and then placed on a conveyor belt and moved thereon by a microwave oven constructed as a tunnel and heated therein by means of the microwave energy mentioned.
  • a dissolving unit for dissolving the flake fleece As a dissolving unit for dissolving the flake fleece, a dissolving unit with a cleaning roller and a grate arranged at least partially around it is advantageously provided next to the feed rollers.
  • a further preferred embodiment consists in that means for cooling the flake cotton wool emerging from the microwave oven are subsequently provided at the output end of the conveyor belt, these means being two superimposed cooling conveyor belts that convey the flake wool between them.
  • 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 are coupled to a halon gas fire extinguishing system via a control system. Should a fire arise in the microwave oven due to 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, for example 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, for example 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 therefrom 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 promoted 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.
  • 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. Should local overheating occur 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 adapted 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 such that, taking into account the throughput speed of the conveyor belt, the honeydew deposits are warmed up to about 140 ° C, which is sufficient to remove about 80% of the water contained therein and the deposits in a well 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. These bumpers 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 at the output speed of the fiber wadding on the conveyor belt 18.
  • 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.
