Abstract

The device has stator tools (26) oppositely arranged by adherence of a work gap (35) of rotor sided machining tools (24). The stator tools work together with the machining tools, and are adjusted by an adjuster (31) in a radial direction for positioning the work gap. The adjuster comprises an inclined storage space, which forms a contact area directly or indirectly. The storage space is relatively relocated against the stator tools, and the stator tools are guided into a guide during a relative displacement.

Description

  • The invention relates to a device for processing feedstock according to the preamble of independent claim 1.
  • Generic devices are used for the comminution of feed material and / or in together of different components composed of feed material, which may also be present in the composite, for the separation of the components with each other to recover them as recyclables for new production operations. Examples of eligible feedstock include the collections of recyclables carried out in the course of disposing of domestic waste, in which plastics are mixed with sheet metal in large quantities. Likewise, an inventive device for processing electrical and electronic waste, such. As vacuum cleaners, telephones, computers, kitchen appliances and the like, whose essential components are plastics and metals. Other applications include the processing of cable scraps of plastic-coated copper or aluminum wires or the processing of scrap tires made of rubber, steel and fabric, or the processing of recycled wood, which is often contaminated with foreign matter such as iron ,
  • In the foreground of the processing of the feedstock is the goal to solve the components present in the feedstock from each other in order to make their separation in subsequent processing steps can. In most cases, this will also be accompanied by comminution of at least one component of the feedstock. Regardless of this, a device according to the invention is also suitable for the exclusive comminution of feed material, which can be present, for example, in unmixed form.
  • The basic construction of a generic device provides a rotor-stator system. Its rotor is equipped with machining tools over its circumference, which are guided past stationary stator tools in the course of the rotation and interact with them. Depending on the type of processing tools while the feed material is subjected to a cutting, shearing, deformation, tearing, chopping or beating process.
  • Depending on the mechanical properties of the feed material, in particular its hardness, tensile strength and silicate content, the processing operation entails that the processing tools are subjected to more or less severe wear, which increasingly leads to a deterioration of the processing result and an increase in energy consumption. The reason for this is the wear-related increase in the working gap between the processing tools, which is counteracted by the fact that from time to time the intended distance between rotor tools and Statorwerkzeugen is restored by radial readjustment of the stator. However, this is possible only to a certain extent, so that at regular intervals there is a need to replace the tools, be it for regrinding their effective edges or their replacement.
  • Since both the readjustment and the change of the processing tools disturbs the operation significantly and the latter even caused a downtime, it is always endeavored in the sense of an economic approach to make the necessary for the readjustment or changing the tools times as short as possible.
  • From the DE 20 2005 013 719 U1 is a granulator known with a rotor occupied with cutting blades, the stator side by means of clamping on the housing fixed counter blade are assigned. A wear-induced radial readjustment of the counter knife is carried out after the clamping and operation of radial screws. Since the counter blades extend over the entire length of the stator and often consist of several juxtaposed individual blades, a great deal of time and effort is associated with the alignment of all counter knife by pressing the individual clamping and adjusting screws. This leads to undesirably long stoppages, which add up over time to a considerable economic disadvantage.
  • Furthermore, from the DE 200 09 718 U1 a sliding shear known, which has a rotatably mounted and driven within a housing rotor, on the lateral surface of a plurality of chopping knives is arranged. On the stator side counter knives are fixed in knife holders, which are mounted around the axis of rotation axis-parallel pivot axes. On a knife holder, two are diametrically opposed attached opposite counter knives, which can be moved and fixed in each case by pivoting the knife holder in the cutting position. In this way, a knife change-related downtime is limited only to the duration of the pivoting operation of the knife holder. The replacement of the consumed counter knife, however, can be done during the crushing operation. Moreover, in the DE 200 09 718 U1 a device for adjusting the cutting gap is addressed, in which the width of the cutting gap is adjusted by a small pivoting movement of the knife holder. However, this type of kerf adjustment brings with it that the counter blade changes its spatial position not only in the radial direction, but also in the direction perpendicular thereto, whereby a total of an optimal cutting geometry is deviated.
  • Against this background, the object of the invention is to provide a device in which the stator tools can be radially readjusted or changed with the least possible obstruction of the machining operation.
  • This object is achieved by a device having the features of patent claim 1.
  • Advantageous embodiments will be apparent from the dependent claims.
  • The basic idea of the invention is to be able to carry out the readjustment or replacement of the stator tools in as short a time as possible. To implement this idea according to the invention, it is provided for the stator tools to be radially displaceable indirectly via a knife holder or directly with the interposition of an inclined footprint. By a relative displacement of the footprint relative to the stator tools, there is a sliding of the stator on the footprint, which brings a lifting or lowering of the stator with respect to the footprint with it. This lifting and lowering movement uses the invention for the radial readjustment of the stator tools, both for adjusting the width of the working gap and for changing the stator.
  • Preferably, the execution of the relative movement between the footprint and Statorwerkzeugen within the device, since in this way the readjustment in extremely short time. Embodiments in which the stator tools are adjusted outside the device to a predetermined radial position are also included in the invention.
  • The invention encompasses all types of relative displacement between the stator tools and the footprint. Thus, it is conceivable to provide the footprint of the peripheral surface of a rotating disc or roller, which is arranged eccentrically to the axis of rotation. Likewise, the footprint may be formed by a flat or curved surface which is displaced tangentially or parallel to the axis of rotation of the rotor. All types of relative displacement lead according to the invention to a conversion of the displacement movement in a radial movement of the stator relative to the rotor axis.
  • Preferred by the invention is an axially directed displacement movement of the footprint, for which purpose corresponding linear guides can be provided within the device. In this way, a relatively large displacement path can be realized, which makes it possible to form the shelves with relatively low inclination. As a result, a sensitive radial adjustment of the stator tools with high precision is possible.
  • In a simple and therefore preferred embodiment of the invention, the footprint of the wedge surface of a wedge member is formed, wherein the base of the wedge member is mounted in a relative displacement enabling guide. In addition to the possibility to provide a single long wedge element along the stator, a further preferred embodiment has two or more successive wedge elements in the axial direction, which allows a compact design of a device according to the invention as a result of the staggering of the footprint thereby achieved.
  • When arranging a plurality of wedge elements, it is advantageous to arrange them on a common base plate, which inevitably results in a synchronization of the relative displacement of the individual wedge elements.
  • In an advantageous embodiment of the invention, a spindle drive or rack drive is provided as a drive for the relative displacement, advantageously a Reduction gear is connected upstream. These drives thus allow a sensitive control of the relative displacement, which can be done both by hand and by means of a motor.
  • In order to decouple the adjusting mechanism from the large forces acting on the stator tools during operation, a clamping device for fixing the stator tools to the stator is provided in an advantageous development of the invention. Preferably, the clamping device consists of two along both longitudinal sides of the stator tools extending clamping bar, one or both of which can be pressed by means of clamping wedges to the stator. Such a tensioning device can be tightened or loosened quickly and therefore contributes to a further reduction of tool change-related downtimes.
  • It is also preferable to combine individual components into an assembly or a package. This assembly or this package may, for example, belong to the parts of the adjusting device to remove the entire assembly as a whole the housing with only one Ausschubbewegung or to use this again. This further shortens the change of the processing tools. This embodiment of the invention is particularly suitable in cases where the stator tools are set outside the housing to a certain supernatant.
  • In this sense, a mechanical ejection of the modules or packages from the housing, for which, according to a particularly preferred embodiment of the invention, a continuation of the linear guide is provided outside of the housing acts. In this way, the individual assemblies are mechanically moved out through openings in the end walls of the housing, where they can be easily, safely and quickly removed and replaced by new due to the thus achieved good accessibility.

  • The Fig. 1 to 3 give an overview of a device according to the invention with the sections and a plan view shown therein. The invention initially comprises an approximately rectangular housing 1, which rests on a frame 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. Down the housing 1 is open through a material outlet 8 for the material deduction. Above the housing 1 is closed, with a central over the entire length of the housing 1 extending rectangular opening 9, to which a vertical, aligned with the opening 9 bay-shaped material inlet 10 connects.
  • On the outer sides of the end walls 3 and 4 each have a center console 11 and 12 welded, which serves to receive horizontal pivot bearing 13 and 14 respectively. In the Bearings 13 and 14, a horizontal drive shaft 15 is mounted, which extends through openings in the end walls 3 and 4 over the entire length of the housing 1 and beyond and whose longitudinal axis forms the axis of rotation 16. Via a coupling 17, a gear 18 and V-belt 19, one end of the drive shaft 15 is connected to a drive 20 in the form of an electric motor.
  • Within the housing 1 can be seen a horizontally disposed rotor 21, which is formed by non-rotatably mounted on the drive shaft 15 rotor disks 22. Each of the rotor disks 22 has uniformly distributed over the circumference of processing tools 24, which are formed in the present example of Schermesserern. All of the machining tools 24 of the rotor 21 describe a uniform circumferential circle 25 during the rotation about the axis 16.
  • In the peripheral region of the rotor 21 below the material inlet 10, one can see stator tools 26 which extend over the entire length of the rotor 21 and which, while maintaining a small working gap 35 (FIG. FIG. 4 ) are radially opposed to the machining tools 24. The stator tools 26 have a profile complementary to the machining tools 24 of the rotor 21 and cooperate with them.
  • The stator tools 26 are arranged in trough-shaped from the end wall 3 to end wall 4 extending knife holders 27, which in turn are each held in clamping devices 28 rigidly relative to the housing 1. Each clamping device 28 is formed by two with a lateral distance paraxial clamping beam 29 and 30, which receive the knife holder 27 in the middle. In this case, the beam 29 is rigidly connected to the end walls 3 and 4, while the opposite beam 30 can be pressed against the knife attitude 27 via a clamping wedge, which in detail even closer from the description Fig. 6 evident.
  • Each stator tool 26 or each tool holder 27 is associated with a radially outwardly adjoining adjustment device 31. The adjusting device 31 is used to adjust or wear-related adjustment of the stator 26, to maintain the predetermined width of the working gap 35 to the rotor side To ensure editing tools 24. The exact structure and function of the adjusting device 31 is among the Fig. 4 and 5 explained in more detail.
  • The lying between the stator 26 lower circumferential portion of the rotor 21 is covered by a semi-cylindrical screen member 32, which is provided with flanges longitudinal edges of longitudinal members 33 and 34 releasably secured. The sufficiently processed feed material leaves the processing zone via the sieve surface of the sieve element 32.
  • To adjust the width of the gap 35, it is necessary to adjust the stator 26 mounted in the knife holders 27 radially, which according to the invention with the in the Fig. 4 and 5 shown adjusting device 31 takes place. In Fig. 4 If one sees a corresponding section of the end walls 3 and 4, between which an axially parallel to the axis of rotation 16 extending linear guide 36 is rigidly secured. The rotor 21 facing side of the linear guide 36 has a encompassing groove 37, so that there is a C-shaped cross-sectional profile of the linear guide 36. The linear guide 36 forms in this way a track for a carriage 38th
  • The carriage 38 is composed of a base plate 39 which corresponds in cross section to the profile of the groove 37. The base plate 39 is significantly shorter than the mutual distance of the end walls 3 and 4, resulting in a displacement in the axial direction. Otherwise, the base plate 39 is held in the longitudinal guide 36 on all sides, so also against tilting or lifting.
  • The carriage 38 further comprises two wedges 40 and 41 which are fixed in the free area between the encompassing longitudinal edges of the linear guide 36 at an axial distance from one another in each case finally with the end of the base plate 39 and rigidly therewith. The extending in the axial direction wedge surfaces 42 and 43 of the wedges 40 and 41 close with an imaginary Lotebene 44 emanating from the axis of rotation 16 extending through the wedge surface 42 radial beam 45 an inclination angle α. The two wedge surfaces 42 and 43 are plane-parallel to each other and together form the footprint 46 for adjustment of the stator 26. For this purpose, the wedge surfaces 42, 43 each have a longitudinal groove 47, 48 corresponding to the base plate 39 encompassing longitudinal edges for receiving the to complementarily trained knife holder 27 has. At the lower end of the longitudinal groove 47, 48 defines a stop 57 the displacement path for the knife holder 27th
  • A drive 49 provides the movement of the carriage 38 within the linear guide 36. The drive 49 includes a pull and push rod 50 which is connected at one end to the back of the wedge 41 frictionally and with its other end axially parallel through an opening 51st extends in an insert part 52, which is inserted in the area in question in a larger opening 53 of the end wall 4 and there forms the end wall 4.
  • In the region of the opening 51 on the outside of the insert part 52, a gear 54 is fixed, which is in engagement with the pull and push rod 50. By actuating the hand wheel 55, the rotational movement is converted into an axial movement of the pull and push rod 50 and thus of the carriage 38 or the footprint 46 in the gear 54.
  • FIG. 4 also shows the between the two end walls 3 and 4 axially parallel to the axis of rotation 16 extending trough-shaped knife holder 27, in which the stator 26 are positively received. One sees the radially inwardly facing the stator 21 facing effective edges 56 of the stator 26, the radially opposite the only indicated machining tools 24 of the rotor 21 while maintaining a narrow working gap 35. Support elements 58 and 59 protrude from the underside of the trough-shaped knife holder 27, whose foot region 60, 61 is formed with a contact surface inclined correspondingly to the inclination of the wedge surface 42, 43 and otherwise complementary to the longitudinal grooves 47, 48. In this way, a longitudinal displacement of the foot portions 60, 61 in the longitudinal grooves 47, 48 given. Not shown, but also within the scope of the invention are embodiments in which the machining tools are carried and adjusted directly without the interposition of a tool holder by the adjusting device 31.
  • For a guide in the radial direction, the knife holder 27 is held between the inner sides of the end walls 3 and 4, where it rests with loose contact. In addition, the two form parallel to the axis of rotation 16 beams 29 and 30 as part of the clamping device 28 more guide surfaces. In the open state of the clamping device 28, the knife holder 27 is thus loose between the clamping bar 29 and 30, thereby allowing a radial adjustment of the stator 26th
  • The radial adjustment is carried out by actuation of the handwheel 55, which initiates an axial displacement of the pull and push rod 50 and thus of the wedges 40 and 41 and, further, the footprint 46. The knife holder 27, however, is prevented from axial movement through the end walls 3 and 4. Instead, there is a relative movement between the footprint 46 and the knife holder 27, in which the foot portions 60, 61 in the longitudinal grooves 47, 48 slide. Due to the inclination of the footprint 46, this leads to a raising or lowering of the knife holder 27 with Statorwerkzeugen 26th
  • The inclination of the footprint 46 thus converts an axial movement of the footprint 46 into a radial movement of the knife holder 27 and thus the stator tools 26. The degree of inclination and the degree of reduction of the gear 54 ensure a precise and sensitive readjustment of the stator 26.
  • The fixation of the stator 26 during processing of the feed takes place via the clamping device 28, the more accurate structure of all of the Fig. 5 and 6 evident. The clamping device 28 comprises the already mentioned clamping bars 29 and 30, of which the clamping bar 29 is rigidly connected to the inner sides of the end walls 3 and 4. In contrast, the clamping bar 30 extends through corresponding openings in the end walls 3 and 4 to the area outside the housing 1. The outside of the end walls 3 and 4 lying end portions of the clamping bar 30 are each bevelled to form a wedge surface 62. This wedge surface 62 at a distance opposite one sees in each case a bearing block 63 which is fixedly secured to the outside of the end wall 3 and 4 respectively. The bearing block 63 also has a wedge surface 64 which encloses a conically extending intermediate space 65 with the wedge surface 63 of the clamping bar 30. In the intermediate space 65, a spring-loaded clamping wedge 66 extends to the wedge surfaces 62 and 63 opposite wedge surfaces 67. Due to the spring bias of the clamping wedge 66 is continuously pressed into the intermediate space 65, whereby a clamping effect of Clamping bar 31 causing lateral compressive force on the clamping bar 31 is exercised. The release of the clamping takes place by a force against the spring bias, which is applied for example by a hydraulic cylinder piston unit 71.
  • In addition, the invention is characterized by the possibility of a simple and rapid change of the stator 26. Like from the Fig. 1 . 2 and 4 As can be seen, the linear guide 36 for this purpose a continuation by arranging a structurally aligned linear guide 68 on the outside of the housing 1. Since the lower edge of the opening 53 is flush with the bottom of the groove 37, it is possible after loosening the insert 52 the Slide 38 including knife holder 27 with stator 26 to pull through the vacant opening 43 axially outward.
  • How out Fig. 4 can be seen, for this purpose, a cylinder piston unit 69 is provided, the cylinder is fixed to the end wall 3 and / or 4, while the movable piston extends through an opening in the end wall 4 and is connected there to a rigidly attached to the insert 52 connecting plate 70. As an alternative to the cylinder piston unit 69, for example, a rack and pinion drive is possible, the force resulting parallel to the guides 36 and 68 acts as close to the carriage 38. For example, the rack may be formed by the underside of the base plate 39.
  • For the replacement of the stator tools 26, first the clamping wedges 66 are relieved at both ends of the clamping bar 30. The light sideways movement of the clamping bar 30, which sets in, releases the knife holder 27. By operating the handwheel 55, the stator tools 26 are lowered until their effective edges 56 are no longer in engagement with the machining tools 24. After loosening the insert 52 and extending the cylinder piston unit 69 is then the entire assembly, consisting of the base plate 39, the wedges 40 and 41 and the knife holder 27 with support members 58 and 59 including the stator 26 through the liberated opening 53 to the outside in the Area of the linear guide 68 shifted. The stops 57 act at the base of the longitudinal grooves 47 and 48 as a driver for the knife holder 27. In the linear guides 68 outside of the housing 1, the stator 26 are good accessible for their removal from the knife holders 27. After replacement of the stator 26 against unused, the new stator tools are placed in the reverse order in processing position and fixed after adjustment of the working gap 35 in this position by means of the clamping device 28.
  • The Fig. 7, 8 . 9 and 10 show further embodiments of the invention for the radial adjustment of the stator 26. For the same features, the same reference numerals of the embodiments described above are used in the following.
  • In Fig. 7 one first sees a base plate 39 which, within a device according to the invention, is guided by the linear guide 36 (FIG. Fig. 4 ) is recorded. The upper side 65 of the base plate 39 is provided with profilings 66, for example in the form of transverse strip-shaped waves or edges (FIG. Fig. 10 ). On the base plate 39 sits with its base surface 68 loosely a wedge 67. The base surface 68 also has profiles 69 which are complementary to the profilings 66 of the base plate 39 are formed. The base surface 68 opposite top of the wedge 67 forms the footprint 46th
  • The footprint 46 carries a knife holder 27 with a trough-shaped receptacle for the stator 26. On the underside of the knife holder 27 is a wedge-shaped projection 70 integrally formed over the entire length. The inclined bottom 71 of the wedge-shaped projection 70 forms with the footprint 46 from a contact joint, whereby it is also possible to provide this contact joint with complementary profiles.
  • The described components form a stator packet or an assembly, which is held together by means of a radial clamping screw 72. In this case, the clamping screw 72 extends from the base plate 39 through the wedge 67, which has an axially aligned slot 73 for this purpose, in a threaded bore 74 in the wedge-shaped projection 70 of the knife holder 27th
  • The setting of the stator 26 is done by pre-setting the height H of the stator, for which the clamping screw 72 is released and the wedge 67 is axially displaced in the context of provided by the slot 73 game relative to the wedge-shaped projection 70 and the base plate 39, wherein the Height H in Dependence of the direction and the measure of the displacement changed. After presetting the desired height H, the clamping screw 72 is tightened, wherein the profilings 66 and 69 and optionally the profiles in the contact joint between the wedge 67 and lug 70 positively engage with each other. Such a preset stator core can then be inserted within the linear guide 36 in a device according to the invention, wherein the stator 26 easily get into their intended position.
  • In the Fig. 8 illustrated embodiment largely corresponds to the already in Fig. 7 described, so that said there applies mutatis mutandis. The only difference is that instead of the wedge-shaped projection 70, which is integrally connected to the knife holder 27, a counter-wedge 75 is welded or screwed to the underside of the knife holder 27. The interacting with the footprint 46 of the wedge 67 wedge surface 76 corresponds to the inclined bottom 71 of the projection 70. Otherwise, there is agreement with the below FIG. 7 described embodiment.
  • In the Fig. 9 described embodiment of an adjusting device comprises two wedges 80 and 80 ', the structural design of which in principle in the FIGS. 7 and 8 described wedge 67 is similar, except that the wedges 80 and 80 'are much shorter in the axial direction. Each wedge 80, 80 'sits loosely on the base plate 39, wherein the contact surface can in turn be formed with complementary profiles 66, 69 ( Fig. 10 ). The footprint 46 is formed by the two upper sides of the wedges 80, 80 ', on which in turn rest the counter wedges 81 and 81' with their inclined undersides 83, 83 '. The counter wedges 81, 81 'are in turn connected to the underside of the knife holder 27, in which finally the stator tools 26 are received. About only with the lines 85, 85 'indicated clamping screws, which extend within the slots 86, 86', the stator is held together.
  • The in the FIGS. 7 to 10 illustrated embodiments of the invention are particularly suitable for the manual removal of the stator from the housing 1 to replace or radially adjust. In this case, the setting of the height H of the stator can be made to a predetermined size outside the device, which advantageously in each case in the course of the change of Stator tools 26 happens. These embodiments are characterized due to the lower design effort, especially in economic terms.
  • The invention is not limited to the feature combinations described in the individual embodiments. Rather, embodiments are also within the scope of the invention, which result from a combination of individual features of different embodiments that is linked to the purpose of the invention.
