Definitions

  • the separating device consists of several sieve cartridges which are arranged in the upper region of the grinding chamber.
  • the grinding chamber is connected to a regrind outlet flanged to the side of the grinding container by three parallel horizontal pipes.
  • a sieve cartridge is inserted into the grinding chamber in such a way that one of them extends radially to the agitator shaft and ends shortly before it, while two further, longer sieve cartridges are arranged on one side of the agitator shaft.
  • sieve cartridges are staggered parallel to the agitator shaft and connected to a grist outlet located above the grinding chamber. In both cases, the sieve cartridges are thoroughly washed around on all sides by the material to be ground, so that they do not clog. However, the sieve cartridges are constantly hit by grinding media during operation, which have been activated directly by the agitator shaft and therefore hit the sieve cartridges with great kinetic energy, so that they wear out quickly.
  • the invention is therefore based on the object of designing an agitator mill in such a way that its separating device is largely removed from the impact of grinding bodies activated directly by the agitator shaft and nevertheless does not tend to clog.
  • the invention has the advantage that the separating device, whatever it may be in the individual, is protected within the cavity open at the end in the end section of the agitator shaft, so that grinding media activated directly by the agitator shaft have hardly any possibility of impacting the separating device . Nevertheless, the risk of the separating device becoming clogged is avoided by the rotation of the agitator shaft.
  • At least one conveying element is preferably formed on the agitator shaft, which promotes an axial flow of grinding media and grinding stock from the inner shaft end through the cavity to the recesses.
  • the conveying element can be formed by the wall of the cavity itself, for example in that the cavity widens conically away from the inner shaft end.
  • the separating device is preferably arranged at least approximately coaxially with the agitator shaft. Depending on the position of the agitator shaft in the room and on the type and nature of the material to be ground, it may also be expedient if the separating device is arranged parallel or at an angle to the axis of the agitator shaft.
  • the separating device can be arranged on a tube which extends through part of the grinding chamber from the inner shaft end into the cavity.
  • the separating device can be installed and removed particularly easily together with the tube.
  • the pipe is expediently guided to be pulled outward in a pipe socket which extends from an end wall of the grinding container into the cavity.
  • the tube is guided to be pulled outwards in a sleeve which is arranged on an end wall of the grinding container and is adjustable between a normal operating position, in which it is arranged essentially outside the grinding chamber, and a position for exchanging the Separating device in which the sleeve protrudes into the cavity and seals off the agitator shaft in a manner that restricts the grinding media.
  • the separating device is connected through the generally hollow stirring shaft to the regrind outlet, which is arranged at an outer shaft end.
  • the separating device can have a tubular sieve cartridge.
  • the separating device can be fastened to the agitator shaft and circulate with it.
  • the separating device has two separating disks which are known per se and are arranged coaxially with the agitator shaft and form an annular gap, one of which is rotatable and the other is arranged in a stationary manner.
  • the lying agitator mill shown in Fig.l to 3 has a box-shaped frame 10 on which a substantially cylindrical grinding container 12 and axially next to this a bearing housing 14 are attached.
  • the frame 10 contains a drive motor, not shown, and is connected to the bearing housing 14 by a gear housing 16, in which a gear, also not shown, with an adjustable transmission ratio is arranged.
  • the grinding container 12 contains a circular cylindrical grinding chamber 18 in which an agitator 20 is arranged.
  • the agitator 20 consists essentially of an agitator shaft 22 which is mounted in the bearing housing 14 and extends coaxially with the grinding container 12 through almost the entire grinding chamber 18, and a number of rod-shaped stirring elements 24 which are attached to the agitator shaft 22 at equal axial intervals and protrude into spaces between counter-bars 26 attached to the grinding container 12.
  • a grinding material inlet 28 through which a suspension or slurry of grinding material and liquid is continuously pumped into the grinding chamber 18 during operation.
  • a grinding material outlet 30 is arranged through which the finished grinding material is continuously pumped out.
  • the regrind outlet 30 is formed by a threaded connector at the end of a tube 32 to which a flange 34 is attached. The flange 34 is screwed to a cover which forms an end wall 36 of the grinding container 12 facing away from the gear housing 16.
  • the tube 32 extends - coaxially with the stirring shaft 22 in the example shown - through the end wall 36 and the adjacent area of the grinding chamber 18 to an end section 38 of the stirring shaft 22.
  • the end section 38 is detachably screwed to the main part of the stirring shaft 22 and points a cavity 40 open at the end or end, in which a separating device 42 is arranged.
  • the separating device 42 is formed by a cylindrical sieve cartridge which has the same diameter as the tube 32 and consists of one piece with this.
  • the separator 42 extends coaxially with the agitator shaft 42 over the greater part of the length of the cavity 40 and has a closed end 44, the distance from the axially inner end of the cavity 40 as well as the radial width of the annular space between the cylindrical part of the filter cartridge and the Inner wall of the end portion 38 corresponds to approximately 15 to 20% of the diameter of the cavity 40.
  • slot-shaped, axially parallel recesses 46 are machined, each of which has an annular sector-shaped cross section and extend over the greater part of the length of the cavity 40, so that the filter cartridge 42 is enclosed by these recesses almost over its entire length.
  • the recesses 46 extend in the shape of an annular sector over an angular range of 45 ° in each case and allow webs 48 of the same cross-section to stand between them, so that the end section 38 as a whole resembles a cylindrical cage which is open at one end face.
  • Three of the rod-shaped stirring elements 24 are fastened to each of the webs 48, so that the end section 38 is completely comparable with the main part of the stirring shaft 22 with regard to the fitting with stirring elements.
  • the agitator shaft 22 rotates, depending on its diameter and the nature of the material to be ground, at a speed which is customary in agitator mills in the order of magnitude of, for example, 200 to 3000 revolutions per minute, as a result of which the mixture of grinding media 50 and grinding material contained in the grinding chamber 18 52 is activated.
  • a negative pressure is generated in the pipe 32 by a pump device, not shown, which allows the grinding media 50 and the material to be ground 52 to flow from the grinding chamber 18 into the cavity 40.
  • the finished regrind passes through the sieve cartridge 42 into the pipe 32, while the grinding media 50 are retained and flow back through the recesses 46 into the grinding chamber 18. This backflow is promoted by centrifugal forces which result from the action of the webs 48 and the stirring elements 24 attached to them on the grinding media 50.
  • FIG. 4 shows a simplified axial section of an embodiment in which the separating device 42 is also designed as a sieve cartridge and is arranged in the cavity 40 of the end section 38 of the agitator shaft 22.
  • the separating device 42 is fastened to the end of a tube 54, which extends through the bearing housing 14 (FIG. 1) within the overall hollow stirrer shaft 22 and is connected there to a regrind outlet which replaces the regrind outlet 30 shown.
  • FIGS. 5 and 6 are comparable in their overall arrangement with FIG. 2; here too, the separating device 42 is arranged on a tube 32 which extends through part of the grinding chamber 18. However, the separating device 42 is formed by two annular cutting disks 56 and 58, which are arranged coaxially with the agitator shaft 22 and delimit a cylindrical annular gap 60 between them.
  • the cutting disc 56 is attached to the agitator shaft 22 and rotates with it; the cutting disc 58 is attached to the tube 32 and is therefore stationary.
  • the stationary cutting wheel 58 is arranged radially outside the rotating cutting wheel 56; according to Figure 6 it is the other way round.
  • Fig. 7 shows a modification that differs from Fig. 5 and 6 in that the two cutting discs 56 and 58 are approximately the same size and axially against each other project so that they form a substantially flat, radial annular gap 60.
  • the cutting discs 56 and 58 could also be conical and delimit a conical annular gap between them.
  • FIG. 8 and 9 show two further embodiments in which the separating device 42, which is likewise formed by two separating disks 56 and 58 and is arranged in the cavity 40, has no component rotating with the agitator shaft 22.
  • the rotatable cutting disc 56 is fastened to a shaft 62 which is arranged coaxially within the tube 32 with the agitator shaft 22 and can be driven by its own motor 64 which is flanged to the wall 36.
  • the stationary cutting disc 58 is in each case attached to the tube 32, according to FIG. 8 radially outside the rotating disc 56; 9, however, axially next to this.
  • a conveying element 66 is arranged around the separating device 42, which is again formed here by a sieve cartridge, which has the shape of a spiral and is fastened within the cavity 40 to the end section 38 of the agitator shaft 22.
  • the conveying element 66 is coiled in such a way that it conveys grinding media 50 and regrind 52 within the cavity 40 from its open end, ie to the left in FIG. 10, when the agitator shaft 22 is driven in its operating direction of rotation.
  • the sieve cartridge which forms the separating device 42, is flowed around substantially uniformly by grinding media 50 and grinding stock 52.
  • the inner wall of the hollow end portion 38 widens away from the open end of the cavity 40 in the shape of a truncated cone.
  • this design causes the centrifugal forces acting on the grinding element 50 and the material to be ground 52 to drive propulsive forces in the direction of the expansion of the cavity 40, that is to say from the away from the open end.
  • the inner wall of the end section 38 thus itself forms a conveying element 66.
  • the separating device 42 which in turn is formed by a sieve cartridge, expands in a manner corresponding to the cavity 40, but only to a diameter which is somewhat smaller than the smallest inner diameter of the cavity 40, so that as in all other embodiments, the separating device 42 can be pulled axially out of the end section 38 and replaced.
  • the conveyor elements 66 shown in FIGS. 10 and 11 can be combined with one another.
  • a pipe socket 68 is arranged on the end wall 36 or a comparable end part of the grinding container 12 according to FIG Screening cartridge trained separator 42 is pulled out.
  • the pipe socket 68 projects into an extension 70 of the cavity 40, but ends at or shortly before the start of the recesses 46, so that it does not hinder the flow of grinding media 50 and regrind 52 through the cavity 40 and the recesses 46 during normal operation .
  • a sleeve 72 can be provided according to FIGS. 13 and 14, which is axially adjustably guided on the end wall 36 and / or a holder 74 fastened to it.
  • Fig. 13 shows the normal operating position, in which the sleeve 72 does not or only slightly protrudes into the grinding chamber 18.
  • the sleeve 72 can be moved into a position in which it engages in a recess 76 of the end portion 38, whereby the interior of the Sleeve 72 is completely sealed off from the surrounding cavity 40 and from the grinding chamber 18. In this position, the sleeve 72 can be fastened so that the separating device 42 can be replaced while the agitator shaft 22 is running, without grinding media 50 or grinding stock 52 being able to flow out.
