Definitions

  • the invention relates to a separation drum for the separation of ferrous parts from a Materialgutstrom.
  • This contains a rotating unit with a drive shaft and a drum shell held against rotation on side discs with an internal, revolving permanent magnet arrangement for guiding the Materialgutstromes.
  • the permanent magnet arrangement has an integer number of pole rods extending axially relative to the drive shaft, preferably four. Their radially outwardly directed magnetic surfaces are alternately magnetized in the circumferential direction of the drum mantle.
  • the pole rods are arranged radially symmetrically on the drive shaft and their magnetic surfaces directed to the inside of the drum shell, that results on the outside of a magnetic adhesion region for iron-containing parts in Materialgutstrom.
  • the invention further relates to a device for the separation of ferrous parts from a Materialgutstrom.
  • both solids with a high iron content and solids containing only a small or without an iron content e.g. Insulators such as glass, silicate, clay, porcelain, plastic, pulp and organic residue.
  • the iron-containing solids can be large in area, e.g. Sheets, etc., have a compact shape, e.g. Iron cores of electric motors, support pieces, etc., or be compact, e.g. Screws, bolts etc.
  • FE-separator For the separation of such iron-containing parts in a mechanical way from a Materialgutstrom, which also contains insulators and particles of non-ferrous metals, such as aluminum and copper, this is fed to a so-called FE-separator.
  • This has a separation drum with an arrangement made of permanent magnets inside and a rotating drum shell.
  • the permanent magnets By the permanent magnets an adhesion region for iron-containing parts is generated on a part of the drum shell. If a material material flow is supplied to the drum shell, the iron-containing parts are held on the adhesion region. This has the consequence that they are led further around the drum shell as insulators or non-ferrous particles, and thus fall due to the decrease of the magnetic attraction forces of the permanent magnet assembly and the action of gravity in other angular segments of the drum shell.
  • the number and strength of the permanent magnets used and the number of poles are usually designed so that iron-containing parts detected in all sizes, shapes and densities of Anhaft Scheme and on the drum shell until reaching the for throwing entrained by FE parts.
  • iron-containing constituents should be well attracted in a material flow despite a high dead weight in relation to a small surface area.
  • These should adhere well to the mantle of the drum and be able to be pulled around the drum far enough. They are thus due to their own weight and the decrease of the magnetic field effect, e.g. delayed on the underside of a conveyor belt guided around the separation drum, i. safely fall off on the side of a separating vertex intended for collecting iron-containing constituents.
  • a bulk material flow has, for example, predominantly compact metallic components and if the force of attraction exerted thereon by the magnet arrangement in the separation drum is too great, the problem arises that foreign substances, between the parts, eg sheet metal pieces, and the drum shell or a conveyor belt guided thereon, For example, pieces of plastic, trapped and taken, ie kidnapped, be. These Only fall together with the iron-containing components in the appropriate discharge zone and contaminate the rejected FE fraction.
  • the magnetic attraction force exerted by the permanent magnet assembly can be mitigated.
  • this is possible by selecting and installing a correspondingly designed separation drum, in which the permanent magnet arrangement has less strong or a smaller number of permanent magnets and / or a small number of poles.
  • this would require considerable time and cost-consuming reconstruction measures in practice, such retrofitting in recycling plants is usually not performed.
  • electromagnets inside the separation drum.
  • An arrangement with electromagnets is structurally complex, since the electromagnets from the outside, e.g. via sliding contacts must be powered by a separate power supply.
  • high running costs occur due to the constant power consumption and increased maintenance measures.
  • a drum magnet separator known from the DE 963 322 B.
  • a fixed permanent magnet system is disposed on arcuate support strips within a rotating drum, which extends over a portion of the drum circumference.
  • a change in the field strength of the magnets too this makes it possible for a frame carrying the magnetic pieces to be suspended in a pivotable manner at a point eccentric to the axis of rotation of the drum and to be adjustable by means of a gear which can be operated through the hollow axis of rotation of the separator.
  • the permanent magnet arrangement is arranged fixed in the interior of the drum.
  • the strength of the magnetic field over a region of the drum shell can not be changed uniformly by the pivoting of the frame with the magnet pieces.
  • the invention is based on the object, a rotating separation drum with a revolving permanent magnet assembly inside and equipped with such a separation drum deposition device so that an adjustment of iron-containing parts in a Materialgutstrom applied magnetic attraction in a simple and drum shell uniform manner is possible ,
  • the pole rods in the drum shell of the separation drum are radially symmetrical to the drive shaft in the direction of the inside of the drum shell off or from the inside away in the direction of the drive shaft retractable.
  • the inventive design of the separation drum makes it possible that the distance between the radially upper magnetic surfaces of the pole rods to the inside of the drum shell and thus the density of the outward magnetic field lines in the adhesion region for iron-containing parts on the outside of the drum shell is in particular continuously adjustable.
  • a further, particularly advantageous embodiment of the invention has adjustment means for retracting or extending the pole rods, which can be operated from outside the side windows.
  • the adhesion effect can be adjusted to different large iron-containing parts, eg during a short standstill without the need for reconstruction or substantial interventions.
  • this offers the advantage that the separation drum can be quickly changed over to changed compositions of a supplied Materialgutstromes, and optimizations of the system can be made without significant downtime during operation.
  • a device designed according to the invention for the separation of iron-containing parts from a material material flow has such a separation drum and means for feeding the stream of material material to the drum shell.
  • the invention offers the particular advantage that the magnetic attraction force emanating from the separation drum can be adapted in a simple manner to the current composition of a material material flow and to changed requirements of the application-dependent desired deposition results.
  • the desired separation result is thus adjustable.
  • the magnetic attraction force can be determined by means of the invention e.g. be set so that poorly magnetizable parts with a low FE content and small, e.g. spherical parts are less attracted. These then fall earlier from the drum shell and enter the fraction with non-ferrous components. This, in turn, results in a higher purity of the fraction intended for ferrous constituents. In addition, less by-catch occurs due to carry-over of undesirable components, e.g. Plastics in this fraction.
  • the magnetic flux density required for generating a magnetic attraction on the outside of the separation drum can now also be adjusted in an application-dependent manner in the case of a robust, low-maintenance separator with an internal, revolving permanent magnet arrangement without costly conversion measures. It can thus be dispensed with the use of electromagnets.
  • the separation drum T of the invention is used for the separation of ferrous parts from a Materialgutstrom M. This is in the example of Fig. 1 introduced via an additional conveyor belt E. These are exemplified by different forms such as large solids M1 with high FE content, eg sheets, compact solid M2 with high FE content, eg iron cores, small solids M3 with high FE content, eg screws, small solids M4 without FE share , eg broken glass, and large solid M5 without FE-component, eg insulators or particles of a non-ferrous metal, symbolizes.
  • the separation drum T includes a rotating drum shell T1 with a drive shaft T2 made of a non-magnetizable material, eg stainless steel V4A or manganese steel.
  • the separation drum T according to the invention thus makes it possible, for example, to indirectly guide a material material flow M via an additional conveyor belt E, as in the example of FIG Figures 1 and 2 is shown.
  • the use of the separation drum T according to the invention is not limited to this application. This can also be used, for example, as a separate component in a complex technical system.
  • the permanent magnet arrangement P has four pole bars P1, P2, P3, P4 mounted radially symmetrically on the drive shaft and mutually magnetized in the circumferential direction of the drum shell T1.
  • Their radially symmetrically outwardly directed lateral surfaces P19, P29, P39, P49 thus have alternately a magnetic south or north pole, ie over the circumference of the drum shell T1, the magnetizations N, S, N and S are evenly distributed.
  • the permanent magnet assembly P may also have a different, integer number of pole rods, for example, 2, 6, 8 ..., ie higher or lower pole.
  • the drum shell T1 together with the side windows T3, T4 and the internal, revolving permanent magnet arrangement P and the drive shaft T2 of the separation drum T form a rotating unit. All elements are held against rotation on the drive shaft T2.
  • the permanent magnet arrangement P fills the drum jacket T1 radially symmetrically.
  • the means for feeding the Materialgutstromes M also have a conveyor belt G.
  • This provides a Auf well Scheme G1 for Materialgutstrom M, is performed to form an adhesion region G2 for iron-containing parts M1, M2, M3 to a portion of the drum shell T1, and advantageously outside the display areas of Fig. 1, 2 closed in a ring.
  • the pole rods P1, P2, P3, P4 of the permanent magnet arrangement P in the drum shell T1 radially to the drive shaft T2 towards the inside TI of the drum mantle T1 extendable or again away from the inside TI toward the drive shaft T2 retractable.
  • the radial distance A of the top magnetic surfaces P19, P29, P39, P49 of the pole bars P1, P2, P3, P4 to the inside TI of the drum shell T1 and thus the density of the magnetic field lines in the adhesion region G2 for the ferrous parts M1, M2, M3 the outside TA is currently adjustable by a plant operator depending on the respective degree of utilization of the deposition device.
  • FIG. 2 So shows Fig. 2 the separation drum T of Fig. 1 in a state in which the pole rods P1-P4 of the permanent magnet arrangement P are retracted according to the invention in the direction of the drive shaft T2.
  • the magnetic flux density and thus the force exerted on iron-containing parts on the drum shell attraction are thus reduced.
  • Fig. 2 This can be seen from the fact that the magnetic surfaces P19, P29, P39, P49 are withdrawn with the alternating magnetic north and south poles N, S in the interior of the drum shell T1 and take a much greater distance A to the inside TI.
  • This adjustability according to the invention allows an application-dependent adaptability of the deposition effect exerted on iron-containing parts M1, M2, M3 in a material material flow M, and thus a controllability of the composition of the respective discharge streams.
  • both small solid particles M4 without FE component, eg broken glass, and large solid particles M5 without FE component, for example insulators or particles of a non-ferrous metal slide off the drum shell T1 in a first discharge zone G3. They form a first discharge stream B1, which is in Fig.
  • the local second discharge stream B2 contains solid M1, M2, M3 with FE-share and accumulates to the left of the separating vertex BS.
  • Fig. 2 However, only large solids M1 are held with high Fe ratios, such as sheets, in the adhesion region G2 and taken on the conveyor belt E far to the drum shell T1. These thus form a fourth discharge stream B4 of large-area solids with FE content, which in the example of Fig. 2 accumulates to the left of the separating vertex BS.
  • both compact solids M2 with high Fe contents, eg iron cores, and small solids M3 with a high FE content, eg screws, are less strongly attracted in the adhesion region G2.
  • These thus fall earlier from the drum shell T1 and form with the small solids M4 without FE-share, eg glass splinters, and the large solids M5 without FE-share, such as insulators or particles of non-ferrous metal, a third discharge stream B3.
  • This accumulates in the example of Fig. 2 to the right of the separating vertex BS.
  • a less pronounced separation of solids with or without iron content is effected, but large solids with a possibly high FE content are preferred and thus separated separately.
  • the attraction effect on iron-containing parts and thus the respectively desired degree of separation of the separation drum according to the invention can be optimally adjusted.
  • a machine operator can adjust in such a case any application-dependent desired intermediate position between the fully extended or retracted state of the pole rods.
  • a quantity of material may be collected by a user e.g. be fed several times in succession to the separator C. If the adjustment of the separator according to the invention is adjusted between these runs, i. the distance A of the magnetic surfaces of the pole rods adjusted from the inner wall, so specific specific particles can be obtained from the Materialgutstrom.
