Definitions

  • the invention relates to a method and a device for sorting waste glass.
  • Waste glass is usually in a mixture of different colored glass. A separation into the different color components is necessary for an economical recycling of the old glass. This applies in particular to colorless waste glass, since even small amounts of colored glass, such as green or brown glass, preclude recycling for the production of objects made of colorless glass. It is also important that when sorting waste glass, the non-glass components such as porcelain, earthenware or ceramic parts are also safely sorted out.
  • EP 0 328 126 A2 discloses a method and a device for sorting waste glass, in which fragments with an edge length between 5 and 50 mm are produced by means of a crusher. These fragments are separated and then supplied to color recognition units, preferably on light transmitters and receivers that measure absorption. Depending on the value of the light flow, the fragments are then transferred by flaps or other swiveling parts to certain slides in a switch-like manner and passed through the slides sorted into colors into assigned sorting containers.
  • any number of glass fragments per time can be sorted by arranging any number of slides leading to the color recognition units in parallel.
  • the object of the invention is therefore to propose a method and a device for sorting waste glass, with which a greater throughput of waste glass can be achieved while the quality of the white glass being produced remains undiminished.
  • This object is achieved in a generic method in that the isolated fragments run over a slide as they pass the color recognition device, that they are acted upon by the pneumatic separating device on the slide in the plane of the slide, but perpendicular to the raceway, and are collected next to the slide.
  • a device is characterized in that a sliding chute is provided, on which the color recognition device and the pneumatic separating device are arranged, and in that the pneumatic separating device has compressed air nozzles, which allow the passing fragments to be pressurized with compressed air in the plane of the slide, but perpendicular to the track.
  • flaps or swivel parts from the prior art is therefore replaced by a pneumatic separating device.
  • this has the advantage that the mechanical parts which are subject to natural wear and tear and which have previously come into contact with the glass fragments are eliminated.
  • pneumatics with compressed air nozzles can also be provided for the separation of the glass fragments, in particular one such as is known from the subsequently published DE 39 14 360.
  • a central supply of compressed air can then be used jointly for both parts of the waste glass processing system, which significantly reduces costs and space.
  • a pneumatic separation device with compressed air nozzles enables a very quick reaction to the measurement results of the upstream color detection device. It follows that the separating device can be arranged relatively close to the measuring point of the color detection device. It should be taken into account that the glass fragments move at a certain speed and the color detection device and then the pneumatic separation device require a finite time to process the measurement and to be able to react accordingly. This average response time must be multiplied by an average speed by the minimum distance the measuring point of the color recognition device and the position for the ejection of the glass fragment from its unobstructed direction of movement.
  • the distance from the measuring point to the discharge can be reduced to a size of about 20 cm.
  • This deviation which in extreme cases leads to a particle to be discharged not being correctly detected, is kept very small if the distance between the measuring point and the discharge position is kept as short as possible.
  • a blowout in free fall has the disadvantage that the very irregularly shaped and different heavy glass fragments react very differently to the exposure to compressed air depending on their respective position in the trajectory. Glass fragments that are not acted upon also have very different trajectories depending on their size and shape and the resulting air resistance, since different parabolas are described in each case. This affects the accuracy of the system and leads to a higher frequency of errors and thus to a reduction in the quality of the white glass or - with a corresponding increase in requirements - to an increase in the number of incorrectly undetected white glasses, which are sorted as colored glass and thus lead to a reduction in the white glass yield.
  • the solution according to the invention carries out the pneumatic removal of the particles from their path in a clearer positional state of the fragments, namely when sliding on an inclined slide. They are pressurized with the compressed air within the plane of the slide, essentially perpendicular to their path, that is, approximately horizontally.
  • the particles can be collected directly next to the actual path in collecting shafts, so that misorientation by swirling or rotating fragments is completely excluded. As soon as the fragments have left the actual slide, they can already be assigned.
  • the invention enables a further improvement step which also allows brown or green glass to be separated from the white glass in the same operation.
  • the color recognition device was equipped in such a way that it recognized from its measurement whether it was white, green or amber glass or traded an undefined color.
  • This measuring device then set all subsequent swivel parts, flaps and other soft-like elements in such a way that at the end the glass fragments separated by color were fed to certain sorting containers.
  • Another problem here is that there is a longer period of time with the above-described disadvantages between the measuring point and exceeding the last switch to be traversed. Although these disadvantages could be limited by a particularly favorable arrangement and relative assignment of the individual switch positions, the problem remains in principle.
  • this is done in that the fragments pass several measuring positions of the color recognition device while running over the slide, depending on the color recognized the fragment between the positions of the color recognition device is discharged by the pneumatic separating device to an assigned collecting shaft.
  • a device suitable for carrying out this method is characterized in that positions of the color detection device and compressed air nozzles of the pneumatic separation device are provided in succession and alternation on the slide, the positions of the color detection device each recognizing differently colored glass portions.
  • each individual measuring position is now only responsible for recognizing a very specific color component; one measurement only has to be concluded whether, for example a piece of glass is green or not. From the fact that a piece of glass has reached a certain measuring position, the corresponding measuring results at the previous measuring points can already be inferred automatically. This can be taken into account by suitable programming of the data processing which controls the pneumatic separating device.
  • the order in which the color recognition device detects the different colors at the individual measuring positions can be selected according to optimal criteria. Since the requirements for the optical purity of white glass are highest, it is advisable to discard this component first. Particularly high demands can be made.
  • This component is made up of certain, relatively rarely occurring colors, such as blue glass, heavily soiled glass fragments that can no longer be clearly identified, and those that, for example, could not be classified due to their size or shape. These glass fragments can either be collected separately or, if appropriate, previously some other of the components are supplied for which less high purity requirements apply.
  • a magnetic sensor or the like is used as the measuring point instead of the optical sensors of the color recognition device.
  • a device for optically classifying and separating non-glass parts is known from FR 25 76 008 A1 or DE 36 12 076 A1.
  • a device is not suitable for the color recognition of the individual Gles fragments and separates ceramic material.
  • light barriers are provided behind the compressed air nozzles of the pneumatic separating device and in front of the following measuring position of the color detection device transversely to the slide chute. These light barriers detect the passage of fragments of glass.
  • This measurement together with the data of the measurement positions of the color recognition device, provides a possibility for checking whether a glass fragment that has just been recognized in color has actually been removed. If this is not the case, a corresponding signal can be sent to the following measuring positions are transmitted to allow certain predetermined reactions to take place. For example, it can be specified that a color-recognized but not ejected glass fragment is assigned to the next qualitatively desired quantity of glass fragments.
  • a piece of metal that has not been discharged can run through to the end of the slide, etc.
  • conclusions can be drawn about malfunctions of the blow nozzles of the pneumatic separating device, the system can be stopped if necessary, or other measures can be initiated.
  • collecting shafts are provided in addition to the slide chute, in which the discharged glass fragments are collected.
  • Such a construction primarily reduces the overall size of the entire system, since no additional space is required in the horizontal direction, since the shafts are essentially below the slide chutes.
  • the walls of the collecting pipe, on which the glass fragments that have been discharged hit, are designed in such a way that they prevent the glass fragments that hit them from being reflected back onto the slide. This is made possible by a suitable choice of material and also by a bevel, which forces the glass fragments to reflect downwards, i.e. in the direction below the plane of the slide chute. At the same time, these walls of the collecting shafts are held interchangeably, because they are exposed to the greatest material stress.
  • the collecting cross-section or the size of the collecting area of the collecting shafts in the slide chute level can be dimensioned extremely small, since the impact area of the glass fragments can be determined very precisely by the very targeted and precise discharge. This is a further advantage of the very short distance and above all the defined position of the glass fragments on the slide at the moment of discharge.
  • the small dimensions, particularly in the plane of the slide chute, have the advantage that a relatively large number of slide chutes can be arranged next to one another in a space-saving manner without requiring a great deal of space for the collecting shafts, which in this case are between the various slide chutes.
  • the waste glass obtained is moved in the direction of arrow 1 via a Hopper 2 fed to a crusher 3, in which the waste glass is crushed in such a way that mainly fragments with an edge length of 5 to 50 mm are formed.
  • the waste glass leaving the crusher 3 arrives at a conveyor 4 to which a cleaning device 5 is assigned.
  • This cleaning device 5 can for example work with air or sandblasting or possibly also with water jets 5a and act on the waste glass located on the conveyor 4. This cleaning process removes the paper parts adhering to the fragments as well as the adhering dust and also sweeps away smaller fragments.
  • the impurities and glass fragments and, if applicable, the sand or water used are passed through a separating or separating device which is not shown in the drawing.
  • the fragments remaining on the conveyor reach a classifier 6, which is designed as a screen classifier and through which the supplied glass fragments are sorted into several fractions of different sizes. From the classifier, the fragments with an edge length of less than 5 mm reach the collecting container 7, from which they can be removed as mixing glass for further processing.
  • Sorted fragments with edge lengths of 5 to 50 mm are collected separately in the remaining collection containers 8a-8c, so that 3 fractions Shards of different sizes are obtained, with different colored glass fragments as well as porcelain, clay and ceramic shards and possibly also metal parts being mixed in each fraction.
  • each collecting container 8a-8c is assigned such a conveying device 9, via which the glass fragments which arrive in each case on this conveying device are transferred to a storage container 10.
  • Each storage container 10 is equipped with a device for separating the glass fragments fed to it.
  • a separating device 11 is shown in FIG. 1 in the form of a slide connected to the storage container 10.
  • the separation of the fragments can take place, for example, in that the storage container 10 is designed as a vibrating vibration container with correspondingly installed baffles, which ensure that the glass fragments reach the slide 11 designed as a separation device and are then separated on the slide.
  • the glass fragments pass from the separating device 11 onto the inclined slide 12.
  • the slide 12 is equipped with as little friction as possible against glass-causing material, for example also a glass bottom.
  • Various devices are provided along the slide 12. These are various elements of a color recognition device 14 and a pneumatic separation device 15.
  • the color recognition device 14 has a plurality of measuring points 14a, 14b, 14c, which in turn consist, for example, of light transmitters and receivers. This enables, for example, an absorption measurement.
  • Each of these measuring positions 14a, 14b, 14c of the color recognition device 14 recognizes a different color property of the passing glass fragments.
  • either the sensitivity of the sensor or the color spectrum of the light transmitter can already be set accordingly, but it is also possible, in addition or instead of this measure, to equip or program a connected data processing device accordingly.
  • the color recognition device 14a is, for example, able to recognize colorless glass, the measurement position 14b recognizes green glass and the measurement position 14c brown glass.
  • Compressed air nozzles 15a, 15b, 15c of the pneumatic separation device 15 are arranged between the measurement positions of the color detection device 14. These are located in the side wall of the slide 12 and are able to deliver compressed air in the plane of the slide, but perpendicular to the track of the glass fragments. If such a compressed air jet hits a passing piece of glass, it becomes his Web deflected, to the wall opposite the wall equipped with the compressed air nozzles 15a, 15b, 15c. This can best be seen in the perspective illustration in FIG. 2.
  • Collecting shafts 16 are provided in this wall. These have openings into which the glass fragments enter, provided that they are deflected from their path by exposure to compressed air.
  • Each measuring position 14a, 14b, 14c of the color detection device 14 is followed by a compressed air nozzle 15a, 15b, 15c of the pneumatic separation device 15. If a measuring position detects a glass fragment of the color to be recognized by it, it instructs the compressed air nozzle downstream of the pneumatic separating device 15 to discharge this glass fragment by applying compressed air to it. Since the distance between the elements 14a, 15a, etc.
  • the removed glass fragment hits due to the very precisely predictable external conditions exactly in the opening of the collecting shaft 16, from which it does not bounce back on the slide, since this is prevented by the corresponding geometric shape and material properties of the walls of the collecting shaft 16.
  • a light barrier 18a, 18b, 18c is provided behind the compressed air nozzle 15a, 15b, 15c of the pneumatic separating device, which checks whether the particle to be discharged is actually no longer on the slide 12 or vice versa, whether a particle that cannot be discharged is also was actually not removed. This can be achieved by a suitable electronic connection of the light barrier to the color recognition device 14. The corresponding parts of the data processing unit are not shown.
  • a further measuring position 19 is provided in front of the measuring positions of the color detection device 14 for a metal detector, which can work, for example, on an inductive and magnetic basis. He checks whether a passing fragment is possibly metallic and discharges such metallic fragments in advance via a compressed air nozzle 15d, likewise via a collecting shaft 16.
