Definitions

  • the invention relates to a centrifuge drum according to the preamble of independent claim 1.
  • centrifuges for drying wet substances or moist substance mixtures centrifuges in various embodiments are widely used and are used in a variety of fields.
  • discontinuous centrifuges such as peeler centrifuges
  • suitable means eg via a chute
  • the centrifuge is stopped after separation of the mixture and the deposited solid cake is removed manually from the drum.
  • centrifuges All of these types of centrifuge have long been well known to those skilled in the art and are e.g. in the standard work "Industrial Centrifuges", by Prof. W. Stahl, DrM PRESS, described in detail.
  • the centrifuge drum itself is usually designed as a hollow cylindrical basket having in its peripheral surface a plurality of drain holes through which the centrifuged liquid phase is discharged from the centrifuge drum to the outside. That is, the drum of filter centrifuges is in regular patterns, e.g. drilled at intervals of a few centimeters to discharge the filtrate, ie the liquid phase, through the drum shell.
  • the inner peripheral surface of the centrifuge drum is often provided with an additional filter medium, e.g. lined with a filter cloth on which the solids cake is sedimented during the centrifugation.
  • the filter medium initiates the cake formation by its blocking effect against the oncoming solid in the suspension. It is particularly important to ensure that the filter medium is secured against any circumferential displacement, for example, when filling or peeling tangential acceleration or cutting forces can occur, as well as a backup against axial displacements is provided so that the filter cloth against shifts along the axis of rotation of the centrifuge drum is reliably secured.
  • the filter cloth was laid by the meter on a support fabric and was laid in two half-circumference sections with respective overlaps so that the incoming suspension can not get between the two halves of the cover, thus showing the upper fabric against the running direction.
  • a disadvantage of this solution is, above all, that overlapping results in a double filter cloth resistance, which can lead to a reduced cake thickness at these overlapping points. Likewise, the dehumidification is worsened at these locations. In addition, a symmetrical design of the overlap is necessary to prevent imbalance at the joint.
  • a significant improvement over the overlapping wipes are the endless prefabricated filter cloths in cylindrical form which additionally provide some comfort, i. In particular, a simplification in installation or removal offer. In addition, they significantly alleviate the problems of overlapping filler cloths, especially in critical filtrations.
  • Such cylindrical, but also open filter cloths are heretofore fixed at both ends of the drum in a groove or groove, e.g. are milled circumferentially in the drum shell after production of the drum,
  • the filter medium for example, the filter cloth is thereby wrapped near the front and back of the centrifuge drum in the example dovetail-like circumferential grooves or grooves mentioned above, and the free supernatant of the filter cloth is then simply cut off.
  • the filter cloth is clamped into the groove or groove using a cord made of fine chrome-nickel steel or a round cord made of rubber with a circular cross-section.
  • a certain improvement bring inflatable seals, which are used in place of the Consstemmenden cord or round cords and allow rapid installation and removal of the filter medium.
  • the drum is provided at both ends with a dovetailed recess, in which the inflatable sealing rings are embedded.
  • Another known method is the attachment of the filter cloth by means of a quick release ring in a groove or groove.
  • Fig. 1 is exemplified a known from the prior art centrifuge drum 1 'shown schematically, in which a filter cloth 6' in a in the circumferential direction 8 'in the centrifuge drum 1' milled joint 700 'by means of a quick release ring 10' is fixed.
  • the centrifuge drum 1 ' comprises, in a well-known manner, a drum shell 3' forming the centrifuge drum 1 'and a drum cover 2', through which, for example, a suspension to be dehumidified can be introduced through the opening 21 '.
  • drum base 200 ' formed, which is coupled to drive the centrifuge drum 1' with a rotary drive, also not shown.
  • the drum shell 3 ' extends in a cylindrical manner along the longitudinal axis 4' of the centrifuge drum 1 'and the drum cover 2' and the drum base 200 'are arranged diametrically opposite the drum shell 3' perpendicular to the longitudinal axis 4 'and thus form the two end surfaces of the cylindrical centrifuge drum 1'.
  • a filter medium 6 ' On an inner circumferential surface 5 'of the centrifuge drum 1' is a filter medium 6 ', in the present case a textile filter cloth 6' is provided, for fixing the textile filter cloth 6 'on the inner peripheral surface 5' of the centrifuge drum 1 'is provided a groove 700', in the filter cloth 6 'is fixed by means of the clamping ring 10'.
  • a circumferential hemstitch 61' is provided at both ends of the filter cloth 6 'in the circumferential direction, into which the tensioning ring 10' is inserted in the centrifuge drum 1 'prior to assembly of the filter cloth 6'.
  • Fig. 2 is schematically shown such a clamping ring 10 ', which in the installed state concentric to the axial direction of the longitudinal axis 4' of in Fig. 2 not shown centrifuge drum 1 'is located.
  • the clamping ring 10 ' preferably has a quick-release device 101', which allows, for example, a known threaded mechanism to increase the circumference of the clamping ring 10 'in the groove 700', thereby clamping the clamping ring 10 'in the groove 700', whereby the Filter cloth 6 'in the centrifuge drum 1' is securely fixed.
  • Schnellspannvorrihchtungen 101 ' which have a ratchet 1011', in which, for example, two jagged surfaces interlock, which can be moved against each other so that the circumference of the clamping ring 10 'can be increased, and thereby the two jagged Coat surfaces with each other, so that the larger circumference, or the clamping or contact force generated thereby in the groove 700 ', is automatically maintained.
  • Such quick release devices 101 ' are well known in other fields of the art. For illustration is in Fig. 2a schematically a special embodiment of such a quick release device 101 'shown.
  • grooves 700 'running in the circumferential direction 8' can be differentiated in the prior art, which are designed differently depending on the requirement or depending on the specific type of fastening of the filter cloth 6 'or on different regions in the centrifuge drum 1' could be.
  • Fig. 3a to Fig. 3d schematically a selection of various known types of joints 700 'is shown.
  • the Fig. 3a and Fig. 3b show grooves 700 ', which at Fig. 3a in the drum cover 2 'or in the drum base 200' are provided, and in the example of Fig. 3b in the inner peripheral surface 5 'of the drum shell 3' are milled.
  • the Nutenkonfigurationen according Fig. 3a and Fig. 3b In this case, they are preferably used when the filter cloth 6 'is pressed into the groove by means of a cord or a round cord as described above.
  • Fig. 3c and Fig. 3d show groove configurations with grooves 700 ', which are preferably selected when, for example, one of the above-described clamping ring techniques for fixing the filter cloth 6' by means of a clamping ring 10 'in the centrifuge drum 1' is used.
  • attachment methods and fasteners described above may be for attaching a filter medium in a centrifuge drum, they all share a common problem associated with the use of a groove for securing the filter medium, e.g. of the filter cloth, as such arises.
  • the object of the invention is therefore to propose an improved centrifuge drum in which a filter medium, in particular a textile filter cloth, can be installed particularly simply, quickly and reliably in the centrifuge drum, or can be exchanged, the centrifuge drum having the highest mechanical stability and at the same time can be cleaned easily and with the greatest effectiveness according to the highest standards of hygiene, so that the disadvantages known from the prior art are largely avoided.
