Definitions

  • the invention relates to a device for treating, in particular bleaching, washing, dyeing, boiling, desizing, mercerizing or the like, a textile product with at least one application container in which the product to be treated is passed over a plurality of rollers and is exposed to the action of a liquor , at least one applicator arranged in the application container adjacent to the web of the goods, the at least one inlet for the liquor to be applied to the goods, a device for supplying thermal energy to form an aerosol of the liquor and at least one outlet device for applying the aerosol under high pressure has the textile product passed by the applicator, and at least one damper for steam treatment with the Fleet loaded textile goods, which is arranged spatially separated from the application container (s) receiving the applicator (s) after a lock, the application container (s) being provided with a device for steam rinsing the features of the The preamble of claim 1.
  • the liquor to be applied to the textile goods is mixed in a liquid bath.
  • a liquid bath Depending on the required process, volumes between approx. 50 l and approx. 1000 l are provided for this liquid bath.
  • the liquid bath consists of a homogeneous mixture of various individual components, i.e. the suitable chemicals and usually also water.
  • EP-A-0 362 591 it is known to arrange an applicator adjacent to the web of the goods, which has an inlet for the liquor to be applied to the goods, a device for supplying thermal energy to form an aerosol of the liquor and an outlet device for applying of the aerosol under high pressure on the textile goods passing by the applicator, furthermore a damper for steam treatment of the textile goods charged with the liquor, which is arranged after a lock spatially separated from the container (s) holding the applicator (s), the the applicator (s) receiving container is provided with a device for steam rinsing.
  • the liquor applied via the applicators is activated directly on the textile goods, so that an exact application can be carried out, as a result of which the required amount of liquor can be kept low.
  • a device of the initially named kind which is characterized in that the / the applicator (s) immediately means for mixing a number of individual components he d to the goods to be applied fleet is located upstream in an adjustable composition, wherein the volume the (n-1) th mixing section of the device is less than or equal to the volume of the downstream lines to the applicator (s).
  • the device for mixing the individual components comprises at least one mixing tube with a swirling device, the volume of which each defines a mixing section.
  • the invention also proposes that at least two of the individual components are brought together in a line in front of a mixing tube.
  • At least one of the individual components to be mixed is fed directly to the mixing tube.
  • a further embodiment of the invention is characterized in that the device for mixing the individual components comprises mixing tubes of different mixing qualities.
  • the invention further proposes that to minimize the total volume of the device for mixing the individual components, mixing tubes with a minimum volume are used.
  • the line pressure of at least one component is sufficient to operate the applicator (s).
  • the applicator (s) is immediately preceded by a device for mixing a number (n) of individual components of the fleet to be applied to the goods in an adjustable composition, the volume of the (n-1) th mixing section of the device being less than or equal to that Volume of the redesigned lines to the applicator (s).
  • the applicators which extend across the entire width of the goods, are located on both sides of the textile goods and are supplied by branches from a common pipeline. According to the invention, the chemicals are mixed in as small a volume as possible before they are separated. It has been found that the liquor volume to be exchanged when the formulation is changed in the device according to the invention is of the order of magnitude of approximately 5 l, that is to say at least a factor 10 below the value for conventional technologies.
  • the device for mixing the individual components comprises at least one mixing tube with a swirling device, the volume of which each defines a mixing section.
  • Mixing tubes as such are known. Appropriate internals can be used to swirl the liquid flow. Every conceivable design of a mixing tube is suitable for the invention, provided that the volume of the mixing section does not exceed the volume of the subsequent line the applicators.
  • At least two of the individual components can be brought together in a line in front of a mixing tube. Premixing then occurs in the line, while the actual swirling then takes place in the mixing tube. At least one of the individual components to be mixed in can also be fed directly to the mixing tube, the feeding being able to be carried out on the circumference of the mixing tube or also into the volume of the mixing tube via a puncturing tube.
  • the device for mixing the individual components advantageously comprises mixing tubes of different mixing qualities.
  • a different mixing quality can be specified for each of the mixing tubes, whereby mixing qualities between 30% and 99.9% have been found to be suitable.
  • mixing tubes each having a minimally designed volume are used.
  • the supply of the individual components can be regulated by a flow control, by means of which a number of pumps corresponding to the number of individual components can be operated, unless a corresponding line pressure of the respective component is already present.
  • the admixture is thus determined via the flow, a forced volume flow being applied by the pumps and / or the line pressure.
  • This forced volume flow also has the advantage that the liquor run does not have to be done by gravity alone when changing the recipe. Due to the higher volume flow forced by the pumps, the time required for draining significantly reduced.
  • the device according to the invention has a time for the recipe change of approximately 9 seconds. In known devices, these times are between 15 and 60 minutes.
  • Fig. 1 shows a schematic representation of a device according to the present invention, in which three individual components K1, K2 and K3 can be mixed with a carrier medium water.
  • the water is fed in through a supply line 5, a volume flow being generated by a pump 51.
  • the water is passed through a filter 55 to discharge dirt particles.
  • the amount of water is controlled by a flow meter 52, a control valve 54 and a controller 53.
  • the flow meter 52 detects the amount of water flowing through, passes this value to the controller 53, which in turn is a control valve 54 after sets the required flow rate.
  • a branch 56 is provided for checking the flow accuracy.
  • the supply of water can be blocked via a valve 57.
  • each of the components K1, K2 and K3 is supplied from a container 2, 3, 4 to a controlled system 20, 30, 40, which is constructed identically for each of the components.
  • a controlled system 20 consists of a pump 21 which promotes the corresponding component K1.
  • the quantity conveyed is determined by means of a flow meter 22. This value is transferred to a controller 23, which controls the speed of the pump 21 via a frequency converter 24.
  • the flow rate of the individual components is controlled by a speed-controlled pump, however, as described in connection with the water supply, control is also possible via a regulated valve.
  • a filter 25, 35, 45 is provided in order to remove dirt particles on the volume flow, then the flow accuracy is checked at a branch 26, 36, 46.
  • the supply of the respective component can be blocked by a valve 27, 37, 47 connected downstream of the branch, so that no component can get into the supply line 9 to the applicator if this is undesirable.
  • the first component K 1 is fed to the line 9 at a point behind the sight glass 58 for the water supply 5.
  • a partial premixing of component K 1 and water takes place before they get together into a mixing tube 6.
  • There is an intensive swirling so that a homogeneous mixture of water and component K 1 is present after leaving the mixing tube.
  • This mixture is through another sight glass 61 led with lamp, where the properties of the mixture can be checked.
  • the components K2 and K3 are mixed in a corresponding manner.
  • the component K2 is fed to the line 9 behind the sight glass 61 'so that, in turn, premixing with the mixture already prepared takes place before the component mixture enters a mixing tube 7.
  • the condition of the mixture can be checked in a sight glass 71 with a lamp.
  • the component K3 is fed, the final mixing taking place in a mixing tube 8.
  • the state of the finished mixture is checked in the sight glass 81, again provided with a lamp.
  • the finished mixture is fed to the system of applicators 1, which is designed according to the requirements that are specified by the textile wall to be processed.
  • the design of the mixing tubes 6, 7, 8 takes into account the requirements of the individual components to be mixed, that is, how much effort is required for mixing, what mixing quality should be sought, etc., the volume of which should be kept as low as possible and not that Volume of the downstream lines exceeds. It is advantageous to choose a mixing quality of 95% for the mixing tubes 6 and 7 and a mixing quality of 99% for the mixing tube 8.
  • Fig. 2 shows a further embodiment of the device according to the present invention, in which a plurality of individual components K1, K2, ..., K n are suitably combined to form a mixture. It is possible for each of the components to take on any portion of the volume flow. It is therefore not only possible to use one carrier medium - for example water in the case of the embodiment according to FIG. 1 - with the largest part of the volume flow to mix in a smaller proportion of chemicals. Since a pump delivery is provided for each component, they can be supplied from containers, from tanks or pipelines. The number of individual components to be processed is also arbitrary.
  • controlled system R Any type of volume flow generation or flow control is also possible, so that there are no restrictions here, this part of the pipeline is referred to below as the “controlled system” R.
  • a filter F which removes impurities from the liquid flow, is provided at the end of each controlled system R.
  • this filter F can also be omitted if liquids are free of impurities from the outset or if minor impurities are problem-free for the applicators 1. In the device shown in FIG. 2, such filtering for the component K5 is omitted.
  • the component K1 is fed from a container of the controlled system R and subsequently freed of impurities with the help of the filter F.
  • a volume of component K2 of a delivery line determined by the controlled system R is taken from this volume flow.
  • This component K2 is passed through a filter F and then placed on the main line L.
  • the supply can be introduced on the circumference of the pipe of the main line L, but also via puncture pipes with any immersion depth, so that the supply can take place at any point in the volume flow.
  • a third component K3 is supplied via controlled system R and filter F.
  • a mixing tube M is provided in which the intimate swirling of these components takes place. It is therefore not necessary to provide a mixing tube M after the merging of two components, but rather can Premixing takes place in the lines before the actual intimate mixing begins.
  • the components K2 and K3 do not have to be added one after the other, but the feeds can also be on the same scope (and thus simultaneously) the line of K1.
  • the components K n- 2 are finally fed from a container and K n-1 from a line via controlled system R and filter F to a mixing tube M which opens into the main line L, there to the already existing mixture of components given and again processed in a mixing tube M.
  • the component K n is fed from a container in the usual way and the final mixing is carried out in the last mixing tube M x .
  • the mixture that has now been produced is then applied to the system of applicators 1.
  • the volume to be replaced is between 1 l and 30 l depending on the device and process.
  • the entire device according to the invention can be controlled in the simplest way. Applying the chemicals to the Material web can be made several times in succession with different time intervals in between. Each of these loads can be carried out with different mixing ratios of the same or different chemicals.
  • the individual component doses presented allow a high flexibility of the system.
  • the controllers that are responsible for the flow control of the individual components preferably have an electrical setpoint input so that the setpoints can be controlled by a higher-level computer system for each component depending on the weight of the goods, the conveying speed, the width of the goods and the process to be used.
  • the recipe is therefore preferably stored in the computer system for each article number in addition to the goods weight, width, speed and fleet order data already mentioned.
  • the recipe can be taken over while the system is running.
  • the control can be carried out manually by an operator or semi-automatically by a barcode reader or fully automatically, for example by sensors located on the system. It is possible to ramp up to a maximum flow for a defined short time when changing articles, in order to further shorten the time for the arrival of the new recipe at the applicators.
  • the device according to the invention provides an environmentally friendly and efficient system for treatment of textiles available.
