Definitions

  • the present invention relates to a dimensionally stable ring element for a heat exchange jacket, a heat exchange jacket with a plurality of such ring elements, and a stirred ball mill with such a heat exchange jacket.
  • Agitator ball mills are used in many fields, but above all in those areas in which a ground material is to be ground especially fine, such as. in pigment processing in the paint and coatings industry.
  • An agitating ball mill is used to crush and disperse color pigments and fillers to a very small particle size (such as nanoparticles).
  • the milling process generates heat in the grinding container of the agitator ball mill.
  • agitator ball mills can be provided with a heat exchange jacket, through which a heat transfer medium can flow, whereby a desired temperature control of the milling process is possible. Controlled temperature control of processes in containers may also be desirable in many other applications and is therefore not limited to grinding processes or stirred ball mills.
  • DE-202015101859-U1 discloses a fluid guide mat for directionally directing fluid flow in an agitated ball mill.
  • the heat exchanger shell is formed as a one-piece hollow cylindrical sleeve (eg stainless steel), which extends over the entire length of the grinding container and encloses it.
  • the inner wall of the hollow cylindrical sleeve is provided with a groove which extends helically from one end of the sleeve to the other end of the sleeve.
  • a flexible partition is attached, the inner end of the grinding container is applied, so that a helically extending around the grinding container running channel is formed.
  • a heat transfer medium e.g., water
  • deposits may occur over time that may be detrimental to temperature control and therefore must be removed.
  • the partition may wear out over time, so they must be replaced, otherwise the heat transfer medium no longer flows uniformly through the helical channel around the grinding container.
  • Both the removal of such deposits as well as an exchange of the partition wall is very complex, because first the over the entire length of the grinding container extending hollow cylindrical sleeve must be completely stripped from the grinding container, which can be difficult because the deposits such stripping of Hollow cylinder difficult or even impossible, without causing the partition is damaged.
  • the invention is intended to remedy the situation and eliminate the disadvantages mentioned above.
  • the sleeve comprises at its first end a parallel to the cylinder axis extending projection which is arranged in a predetermined circumferential position on the sleeve.
  • the sleeve comprises a recess extending parallel to the cylinder axis and having a shape complementary to the projection and being disposed in the same predetermined circumferential position on the sleeve as the projection.
  • dimensionally stable with respect to the ring member means that the ring element as a whole, ie considered as a whole component is not changed in a proper use of the ring member in its outer shape, so it is stable in shape. This does not mean that individual parts of the ring element can not be deformable (for example, the partition may have a flexible and thus deformable sealing lip, but it need not, see discussion below), but the ring element as a whole is in intended use of the ring element in stable in its outer form.
  • Such a dimensionally stable ring element allows a particularly simple assembly and disassembly of a quasi-modular heat exchange jacket, which is formed of several individual successively arranged in a row dimensionally stable ring elements, and also makes the complex replacement of the partition obsolete.
  • a positioning aid is created during assembly. This positioning aid allows a simple, error-free, fast and correct position assembly of several such ring elements in a row in a row to one Form heat exchange jacket.
  • the projection and the recess since they are complementary in shape, allow a positive engagement between a plurality of such successively arranged in a row ring elements. As a result, a rotation of the individual ring elements of the heat exchanger jacket relative to each other can be prevented.
  • the projection at the first end of the sleeve has a tooth with a tooth length and a tooth width
  • the recess at the second end of the sleeve has a gap with a gap depth and a gap width.
  • the tooth has a complementary shape to the gap, the tooth length corresponds to the gap depth and the tooth width of the gap width.
  • the tooth and the complementary gap allow a simple and reliable fit of successively arranged in a row ring elements. A possible rotation of two successively arranged in a row ring elements relative to each other is prevented in this way.
  • the gap is dimensioned so that the tooth can be inserted into the gap during assembly and pulled out of the gap during disassembly.
  • the combination of tooth and gap allows easy and quick recognition of the correct mounting position.
  • the projection at the first end of the sleeve has a projection extending along the circumference of the sleeve, which has a projection length in the direction of the sleeve circumference and has a projection width in the direction of the cylinder axis.
  • the recess at the second end of the sleeve comprises a recess extending in the direction of the sleeve circumference, which has a recess length in the direction of the sleeve circumference and a recess depth in the direction of the cylinder axis.
  • the supernatant has a complementary shape to the recess, and the protrusion length corresponds to the recess length and the protrusion width of the recess depth.
  • the protrusion extending along the sleeve circumference and the recess complementary in shape and likewise extending along the circumference of the sleeve also enable a torsion-proof positive connection of ring elements arranged one behind the other in a row and also determine the positionally correct arrangement of the individual ring elements relative to one another.
  • the partition wall extends from the projection at the first end of the sleeve to the recess at the second end of the sleeve helically around the cylinder axis, wherein the partition has a parallel to the cylinder axis extending partition wall width, which is smaller or equal is like the overhang width.
  • a partition width predetermined in this way relative to the projection width (or correspondingly to the recess depth) makes it possible for the dividing wall of a ring element to abut congruently with its partition wall beginning at the dividing wall end against the recess of a ring element arranged immediately adjacent in the row, so that a quasi-spiral, Continuously continuous partition is formed.
  • the dividing wall has a flexible sealing lip on its end facing away from the inner wall of the sleeve.
  • the flexible sealing lip can create the container wall of the process container or grinding container, whereby an optimal sealing effect is achieved.
  • the sleeve is made of a first material having a first modulus of elasticity and the partition of a second material having a second modulus of elasticity, wherein the first modulus of elasticity of the material of the sleeve is greater than the second modulus of elasticity of the material of the partition ,
  • the partition can be bent and thus firmly abut the process container or grinding container, while the sleeve and thus the ring element considered as a whole remains stable in its outer shape.
  • the first material from which the sleeve is made may be polyamide or fiber reinforced polyamide.
  • the second material from which the partition wall is made may be, for example, a thermoplastic elastomer. Both the first material, from which the sleeve is made, and the second material, from which the partition wall is made, are for example injection-moldable materials.
  • the sleeve of the first material with the dividing wall of the second material is produced by a two-component injection molding process.
  • a partition wall produced in this way has a contour adapted to the contour of the container wall of the process container or grinding container.
  • the partition does not need to be installed in a separate step in the sleeve, but the ring member can be made using a two-component injection molding same as a complete component. Accordingly, when a replacement is required, only the ring element to be exchanged according to the invention is replaced by a new ring element, which is cost-effective (favorable production of the ring element, time-saving and simple replacement of a worn ring element by a new ring element). In addition, this also the time required for the exchange, during which the process container is unused, comparatively short.
  • the dividing wall is formed as a helically shaped, dimensionally stable bead which surrounds the cylinder axis and projects inwards from the inner wall of the sleeve.
  • the term "dimensionally stable" in relation to the bead again means that in a proper use of the ring member of the bead does not change in shape, so is stable in shape.
  • a partition with such a dimensionally stable bead is robust and resistant to wear.
  • the dimensionally stable bead must be prepared so that it can not rest against the container wall, but a small radial gap between the container wall and the partition wall remains. Otherwise, at the Mounting the dimensionally stable bead to be damaged (he can break, for example).
  • the sleeve and the dividing wall can be made of the same material by means of a one-component injection molding process.
  • the one-component injection molding process is a particularly cost-effective, reliable and time-saving way of producing the dimensionally stable ring element according to the invention.
  • a heat exchange jacket is furthermore proposed, in which a plurality of dimensionally stable ring elements according to the invention, as described above, are arranged one behind the other in a row, wherein the projection of a subsequently arranged in the row ring element positively into the recess of the respective preceding in the row ring element intervenes.
  • the ring elements arranged one behind the other in a row can not rotate relative to one another, they are thus arranged rotationally fixed. This is achieved by a positive connection between the projection of a respective front ring element in the row and the recess of the respective subsequent rear ring element.
  • Such a heat exchange jacket is further cost-effective to maintain, since not necessarily all ring elements of the heat exchange jacket must be replaced, but only those ring elements can be replaced, which actually require a replacement.
  • Such a heat exchange jacket can also be installed quickly, since the partition wall of the ring elements does not have to be laboriously drawn into the heat exchange jacket, but is already integrated in the ring elements.
  • the heat exchange jacket is arranged around the container wall, so that a helical channel is formed by the helically extending around the cylinder axis around partitions of the ring elements of the heat exchange jacket and through the container wall.
  • the agitator ball mill according to the invention further comprises an inlet and an outlet for a heat transfer medium, the inlet being connected to a first end of the helical channel and the outlet being connected to a second end of the helical channel of the heat exchange jacket facing away from the first end.
  • Such an agitating ball mill has the advantage that it can be mounted and maintained in a simple manner. Furthermore, this agitator ball mill allows efficient temperature control of the process in the grinding container.
  • the heat exchanger sheath can be easily attached to the grinding container by the grinding container is introduced into the heat exchanger shell of the composite and in series successively arranged ring elements or the heat exchanger sheath is pushed over the grinding container.
  • the heat exchanger jacket can be disassembled in the reverse manner from the grinding container (pulling out the grinding container from the heat exchanger jacket or removing the heat exchanger jacket from the grinding container).
  • the heat exchange jacket By placing the heat exchange jacket around the container wall, optimum heat exchange between the grinding container and allows a heat transfer medium flowing through the heat exchange jacket, since the channel for guiding the heat transfer medium is formed so that the heat transfer medium comes into direct contact with the container wall of the grinding container.
  • the heat transfer medium can serve as a cooling medium or as a heating medium.
  • this further comprises a cylindrical outer shell, which encloses the heat exchange jacket.
  • the cylindrical outer shell makes it possible to increase the stability of the heat exchange jacket in addition, since it encloses the heat exchange jacket and thus holds the individual ring elements in addition in position.
  • there is preferably a slight radial play which allows the ring elements of the heat exchanger sheath to be inserted into the cylindrical outer sheath and then to insert the grinding container into the heat exchanger sheath with the cylindrical outer sheath enclosing it or the heat sheath arranged in the cylindrical outer sheath to slide over the grinding container.
  • this comprises a heat exchange jacket of ring elements according to the invention with a partition wall with a flexible sealing lip as described above.
  • the flexible sealing lip has an inner edge with an inner diameter and the container wall of the grinding container an outer diameter.
  • the inner diameter of the sealing lip is smaller than the outer diameter of the container wall of the grinding container, so that the flexible sealing lip is bent and rests against the container wall of the grinding container.
  • the sealing lip is bent in a direction opposite to the flow direction of the heat transfer medium through the helical channel. Characterized the sealing lip is pressed by the heat transfer medium even more firmly against the container wall, whereby the helical channel is well sealed and thus can flow during operation, the heat transfer medium without leakage evenly through the helical channel, which in turn provides a good and uniform heat exchange between the container wall and heat transfer medium can be done.

Accordingly, the heat exchange jacket can be easily removed from the grinding container during disassembly.
  • the assembly of the heat exchange jacket on the agitator ball mill can be carried out, for example, as follows. First, all ring elements are aligned in the same circumferential position with respect to the cylindrical outer shell and inserted in a row in a form-fitting manner in a row in the cylindrical outer shell. The projection and the recess of the respective ring element serve as positioning aids. The lead of each one rear ring element in the series engages after insertion of the ring elements in the cylindrical outer shell form-fitting manner in the recess of a respective immediately before this rear ring element arranged front ring element in the series. The successively arranged in series ring elements thus form the heat exchange jacket.
  • the grinding container in the heat exchange jacket which is surrounded by the cylindrical outer shell, introduced, or the arranged in the cylindrical outer shell heat transfer jacket is pushed over the grinding container.
  • the flexible sealing lip of the respective ring element is bent and abuts against the container wall of the grinding container, so that a dense helical channel is formed.

  • the heat transfer medium nevertheless flows through the helical channel, similar to the first embodiment except for this slight leakage, so that the mode of operation is basically the same as in the first exemplary embodiment.
  • the assembly of the heat exchange jacket 3 with dimensionally stable ring elements 2 according to the second embodiment is identical to the mounting of the heat exchange jacket 3 with dimensionally stable ring elements 1 according to the first embodiment.
