Definitions

  • the invention relates to a device for dissolving the composite of feed material present in the composite according to the preamble of patent claim 1 and a corresponding method having the features of claim 23.
  • the subject of mechanical process engineering is the processing and processing of raw materials into a final product.
  • the subject of mechanical process engineering is the processing and processing of raw materials into a final product.
  • the treatment of waste materials and products is gaining in importance, which in this way will be reintroduced into the production cycle as secondary raw materials.
  • multi-stage processes and plants which are successively passed through by the input material.
  • the individual process steps are in each case formed by devices connected in series, the processing tools of which are adapted to the specific nature of the feed material originating from the upstream process device in terms of size, shape and composition.
  • shredding by cutting devices takes place in each stage.
  • one or more components of the composite material are removed from the feed material in each stage until, ideally, finally, the components of the composite material are completely separated from each other.
  • an apparatus for recycling used tires with a horizontal rotor which is rotatably mounted within a housing.
  • the rotor is equipped with shredding tools over its circumference, which interact with stator tools stationary on the housing.
  • the stator tools are followed by a continuous sieve surface over which the feed material, which has been sufficiently digested and comminuted, is drawn off.
  • the processing of the feed takes place after its task from above, first by its comminution between the rotor and stator and then by further dissolving the composite of the composite components involved between the rotor and Siebober Structure. Due to the constant constructional conditions in the area of the processing zone, a consistent processing of the feed material over the entire sieve length results. This has the consequence that such devices are only suitable for varying in shape and size within narrow limits feedstock, which is why this device is primarily suitable for use within a stage of the overall process described above.
  • the object of the invention is to further develop known devices and methods in order to improve both in terms of the largest possible application of the feed material and in terms of the achievable quality of the final product as well as in terms of economic operation to reach.
  • the basic idea of the invention is to achieve both the combination of the materials involved and their separation within a single device. This is achieved according to the invention by a multi-stage processing of the feedstock, to which the processing path is divided into several successive sections. Each subsection defines a processing zone, each with specific process parameters, which result in a very specific type of processing and are matched in their sequence to both the starting material and the final or intermediate product resulting from the processing.
  • the focus of the type of processing is not the crushing of the feedstock, but the dissolution of the composite material by shearing, tearing, bumping, squeezing, squeezing, rubbing, rolling, kneading, walking, compaction and the like or a combination or sub-combination of these types of processing.
  • the processing in the first section and second section are substantially similar, so that the feedstock is subjected to the same processing several times, with the result of more intensive processing and resulting in higher engine power.
  • another embodiment of the invention provides that constructively configure the successive sections differently.
  • the feedstock in the first section can first be exposed to intense tensile and shear forces, with the aim of coarse dissolution of the material composite, before it in the processing path of the first section shock, friction, kneading and / or compaction forces for further fine resolution of Material composite is subjected.
  • the focus of the processing can then be directed to a comminution of the feedstock.
  • the processing path of the first section produces a pure material digestion through the use of baffles and only in the second section of the deduction of the components of the composite material is performed on screen surfaces.
  • embodiments of the invention are particularly preferred in which the machining path of each section is formed by a screen.
  • a device according to the invention operates more effectively than the one mentioned above and therefore enables a more economical operation.
  • the subsections following one another in the circumferential direction in the circumferential direction of the rotor are the same size or larger.
  • Such a construction takes into account a processing mode in which the feedstock is digested very intensively in the first subsection in order to be removed separately in the subsequent subsection. Due to the increase in volume in the course of processing, more space and a larger sieve area are provided for the discharge in this way.
  • first section larger than the following, resulting in longer residence times in the first peripheral section, for example.
  • Such an embodiment can be used, for example, in the case of feedstock with the participation of brittle materials, where in the first Subsection after departure of the material composite, the brittle material components are deducted.
  • a particularly preferred embodiment of the invention has tool pairings which become smaller in the direction of rotation of the rotor. This sets up a machining process in which the feed material is first exposed to large crushing, shearing and / or breaking forces, while with each reduction in the gap between the stator and rotor tools, the proportion of cutting work is increased and thus the degree of Comminution of the feedstock.
  • suitable sizes of the working gap are without restricting it, for example between 8 mm and 10 mm in the first pair of rotations in the direction of rotation and between 0.3 mm and 2 mm in the direction of rotation last tool pairing.
  • the feed material experiences no cutting in the area of the first pair of tools, but a processing as described above. A predominantly cutting machining then takes place in the region of the second pair of tools, where the width of the working gap is significantly lower.
  • a radial pressure can additionally be generated, with the result of an intensification of the kneading, crushing, flexing, frictional and / or Compaction work and the result of a faster and more complete dissolution of the composite material and an increased Sieb trimgangs.
  • the radial distance between the rotor and the machining paths of the different sections or the machining path of a subsection not constant, but different form. This leads to an alternating sequence of compression and relaxation zones for the feed material, which leads to a particularly intensive digestion of the feed material. Also, the feed is held in areas with a greater distance longer time in this section.
  • the minimum distance between the machining path and the rotor can be 30 mm.
  • the free screen surface in the first section is smaller than the free screen surface in the second section.
  • the feedstock can be held in the first section until a component of the feed material is discharged through the local screen surface, while the second component can then be removed in the second section.
  • the harder component can be held in the first section by suitable sieve selection. There, as a result of forced friction, this component acts on each other like additional processing tools and thus additionally supports the dissolution process of the composite material. The resulting effect is a high degree of separation with low wear.
  • embodiments of the invention are also included, in which the free screen area in the first subsection is greater than in subsequent ones in order to be able to carry out the type of processing on the properties of the feedstock or the requirements of the end product.
  • the sieve forms a specifically adapted to the nature of the feed material processing of the feedstock is possible. Due to the shape and size of the screen perforations, it is possible, for example, to influence the passage of the sieve and the residence time of the feedstock in the respective subsection.
  • the use of so-called aggressive sieves with sharp edges supports the comminution of the feed material, while blunt sieve openings the residence time of the feed material in the enlarge relevant section of the machining path and above all exercise a screening function and less crushing function.
  • the sieves are advantageously designed to be symmetrical to counteract their one-sided wear by turning by 180 °.
  • a particularly preferred embodiment of the invention provides stator tools both at the beginning of the second peripheral portion and at the end thereof.
  • an operation with rotation of the rotor is optional in one or the other direction possible.
  • This initially has the advantage that wear-prone parts are stressed on both sides, that is to say symmetrically, and therefore have a longer service life.
  • asymmetric design of the device is also exchanged with a change in the direction of rotation and the sequence of processing zones, which leads to a different type of processing without modification of the device and in turn causes a change in the digestion of the feed.
  • the stator tools at the end of the processing path can cause additional post-processing of the feed material.
  • FIG. 1 to 3 shows the general structure of a device according to the invention.
  • the invention initially comprises an approximately rectangular housing 1 which rests on a basic structure indicated by 2.
  • the housing 1 has two spaced opposite end walls 3 and 4, which together with the end walls 3 and 4 connecting side walls 5 and 6 enclose a working space 7.

  • a rotor 21 sit within the housing 1 coaxially and rotationally fixed on the drive shaft 15 five with their faces contiguous rotor disks 22.
  • Each of the rotor disks 22 has evenly distributed over the circumference of the processing tools 24.
  • the peripheral regions between the processing tools 24 have a closed approximately cylindrical surface on.
  • the machining tools 24 of the rotor 21 of adjacent rotor disks 22 are arranged at an angular offset from the axis of rotation and describe a uniform circumferential circle 25 during rotation about the axis 16 (FIG. Fig. 2 ).
  • the direction of rotation is indicated by the arrow 23.
  • the processing tools 24 are formed by cutters which have a zigzag or wave course along their active edge and mesh with correspondingly formed stator tools 26 while maintaining a working gap 35.

  • the first section 43 initially comprises in the direction of rotation 23 directly adjoining the feed shaft 10 stator tools 26 which extend in the axial direction over the entire length of the rotor 21 and, while maintaining a working gap 35, the processing tools 24 radially opposite. Due to the width of the tools 24 and 26 extending in the direction of rotation, the working gap 35 has a three-dimensional shape which promotes the processing of the feedstock. As already described, the stator tools 26 have a profile that is complementary to the machining tools 24 of the rotor 21 and cooperate therewith for processing the feedstock.
  • the stator tools 26 are detachably held over their entire length in holders 27.
  • the brackets 27 can be radially adjusted by means of adjustment devices 31 fastened to the housing in order to be able to set the width of the working gap 35 to the desired dimension, for example to a dimension ⁇ 10 mm, preferably ⁇ 8 mm.
  • the stator 26 following in the direction of rotation 23 and extending to about the lower vertex of the rotor 21 strainer 33, which consists essentially of a frame or rust-like filter holder 34 and by means of clamping elements 39 assembled thereon sieve elements 36 composed.
  • the screen 33 is pivotally mounted about an axis 38 to perform maintenance and repair work by opening the strainer 33 better.
  • the working gap 35 'in the region of the stator tools 26' has the same width as the working gap 35 in the area of the stator tools 26.

  • the stator tools 26, 26 'and 26 " have a wave or zigzag-shaped profile which cooperates with the complementarily formed machining tools 24 in the course of the rotation of the rotor 21.
  • Other configurations of the stator and machining tools are also possible, for example straight edges
  • the working gap 35 of each pair of tools can be adjusted individually, with larger working gaps 35 leading to machining of the feedstock mainly by way of cracking and / or shearing, while sufficiently small working gaps 35 'mainly result in a cutting processing.
  • a corresponding gradation of the working column can thus be achieved a gradual transition from a tearing and / or shearing machining to a cutting machining.
  • FIG. 4 embodiment of the invention shown differs from the above essentially only by the nature of the division of the second peripheral portion 42 in the sections 43 and 44 and the abandonment of third stator 26 ".
  • a division of the second peripheral portion 42 takes place in favor of the second portion 44, that is, the second portion 44 has a greater length and thus a larger screen area in the direction of rotation 23.

  • FIGS. 5a to 5g and 6a to 6e show possible embodiments of the sieve elements 36, 36 'of the sieves 33, 33', which can be selected depending on the nature of the feedstock and depending on the desired processing and the nature and properties of the final product to be produced and combined in the sections 43 and 44 with each other.

  • a device according to the invention can be operated by combining and varying the features described above in a variety of configurations.
  • the device is operated with identical sieve elements 36, 36 'in all subsections 43, 44 and with uniform working gaps 35 between the stator tools 26 and the processing tools 24. This initially results in the advantage of greater machine performance already by the provision of additional stator tools 26 'and a better utilization of the screens 33, 33'.
  • an embodiment of the invention is suitable for this, in which the working gap 35 between the stator tools 26 and the machining tools 24 is greater than the working gap 35 'between the stator tools 26' and the machining tools 24, which by means of the adjusting devices 31 and clamping devices 28 fast and can be easily adjusted.
  • a screen 33 is selected with a smaller free screen area than in the second section 44. Due to the width of the working gap 35, this combination results in the beginning of processing to a dissolution of the composite material between the stator 26 and rotor tools 24 by tearing, Shearing, bruising and bumping, exposing the steel inserts.
  • the proportion of the rubber, which has already been sufficiently comminuted, can already be drawn off via the sieve elements 36, 36 'at this early point in time.

If necessary, the working gap 35 'to less than 0.5 mm, for example, 0.3 mm, are set, with the result of a cutting crushing of the feed. With a comparatively larger working gap 35 ', for example between 1 mm and 3 mm, the proportion of cutting work is reduced and the proportion of shearing and tearing increases.
  • Partial partition wall 40 which separates the first section 43 from the second section 44 in the region of the material outlet 8, ensures that the components obtained in this way in the individual sections 43, 44 are not mixed with one another.
  • Embodiments of the invention are also suitable for separating the components of used tires, in which the device has a construction which is symmetrical in cross-section, that is to say that the first section 43 and second section 44 are identical and thus two identical method sequences take place immediately one after the other.
