Definitions

  • the invention relates to a mixer according to the preamble of claim 1.
  • Mixers of the generic type which are also referred to as ring-layer mixers, are known in large numbers, for example from DE-C-20 57 594 (corresponding to US Pat. Nos. 3,734,471 and CH-A-525 702).
  • special measures have been taken in the form of mixing tools tapering towards the container wall in order to dissolve the fibers which tend to agglomerate after gluing, as described in DE-A-24 38 818 (corresponding to US-A -4 006 887) is known.
  • these measures did not lead to the desired success, ie the agglomerates were dissolved.
  • the residence time of the wetted material in the mixer was increased by providing adjustable or regulated outlet flaps at the outlet, through which an adjustable or adjustable back pressure was exerted on the material in order to prolong the dissolving effect to expose the special tools. This led to considerable material caking in the outlet area, which was also not desirable.
  • the invention has for its object to develop a mixer of the generic type so that agglomerates are specifically and reliably dissolved, while at the same time high throughput and high uniformity of wetting are to be achieved.
  • the measures according to the invention ensure that the wetted material, which has largely formed agglomerates, is passed through the cutting devices immediately before reaching the outlet, it being ensured that each agglomerate comes into contact with a knife at least once, but preferably several times and is dissolved.
  • the area of the cutting devices Leaving wetted non-agglomerated material particles are fed directly to the outlet and cannot agglomerate again.
  • the number of cutting devices depends on the size of the mixer and the ratio of the peripheral speed of the mixing tools the axial flow rate of the material. This ratio must be chosen so that all material particles are reliably grasped by them as they pass the cutting devices.
  • - fibrous material such as paper fibers or also wood fibers
  • powder such as lime
  • agglomerates ie agglomerations of several millimeters in diameter
  • the mixer shown in the drawing has a substantially cylindrical housing 1 which is divided in a horizontal plane which is laid through a horizontal central-longitudinal axis 2 of the housing. It consists of a semi-cylindrical housing lower part 3 and a likewise semi-cylindrical housing upper part 4, which are connected on one side by means of swivel joints 5 and which can be connected to one another on the opposite side by means of easily releasable toggle locks 6, so that after releasing these fasteners 6 which is balanced with a counterweight 7, the upper housing part 4 can easily be swung up and away from the lower part 3.
  • the housing 1 is closed at its end faces with end walls 8, 9, which also carry the lower part 3 and end in machine bearings 10, 11. These machine bearings 10, 11 are supported on a foundation 12.
  • a mixer 13 is arranged in the housing 1 concentrically to the central longitudinal axis 2, the shaft 14 of which is led out sealed through the end walls 8, 9 at both ends of the housing 1.
  • the shaft 14 is supported in shaft bearings 15, 16, which are also supported on the machine bearings 10, 11.
  • a pulley 17 is rotatably attached to the shaft, via which a drive belt 18 is guided, which in turn is guided via a belt drive pinion 19 of a drive motor 20, which is also supported and fastened on the foundation 12.
  • a material supply nozzle 22 which is attached to the upper part 4 and - as can be seen in Fig. 2 - opens approximately tangentially into the interior 21.
  • a material outlet connection 23 opens from the interior 21 thereof, which is also arranged approximately tangentially to the interior, as can be seen in FIG. 3.
  • the housing 1 is double-walled, i.e. it has a temperature control jacket 24 through which a temperature control medium, in particular thus cooling water, but also a heating medium, can be passed.
  • a feed zone a is formed, in which feed or acceleration tools 25 are attached to the shaft 14 are.
  • feed or acceleration tools 25 consist essentially of relatively large blades 26, which are set in the axial conveying direction 27 and in the direction of rotation 28 of the mixer 13, so that they accelerate the pourable material 29 fed through the feed pipe 22 in the direction of rotation 28 and set in motion in the axial conveying direction 27.
  • the blades 26 are fastened to the shaft 14 by means of arms 30. As can be seen in FIG. 1, the blades 26 completely overlap in the axial direction; they also extend close to the inner wall 31 of the housing 1, so that there are no dead spaces in which material 29 could be deposited.
  • the mixer 13 is driven at 20- to 40-times the critical speed, so that the material 29 lies directly behind the feed pipe 22 in the form of a material ring 32 on the inner wall 31 of the housing 1, on which it is helical through the interior 21 of the Housing 1 is promoted.
  • the critical speed is understood to be the speed of the mixer 13 at which gravitational acceleration occurs at the radially outer ends of the tools.
  • a wetting zone b adjoins the feed zone a in the conveying direction 27.
  • liquid addition and mixing tools 33 are attached to the shaft 14.
  • These tools 33 can be designed as approximately cylindrical mixing arms which are brought close to the inner wall 31 and which - as can also be seen in FIG. 1 - overlap one another in the axial direction, so that also in the Wetting zone b no dead spaces can arise in which material 29 is not acted upon intensively.
  • the liquid addition and mixing tools 33 are connected to a liquid supply pipe 34 which is guided concentrically to the axis 2 through a shaft cavity 35 of the hollow shaft 14.
  • This liquid supply pipe 34 has liquid outlet openings 36 in the region of the wetting zone b. From these outlet openings 36, liquid supplied by a pump, not shown, enters the shaft cavity 35 through the supply pipe 34. Due to the high speed and the resulting centrifugal forces, this liquid becomes in flung the individual tools 33, flows through them and is dispensed by them at their radially outer end in the form of finely divided liquid 37 into the material ring 32, which is also maintained in the wetting zone b by the tools 33.
  • the rotational speed of the material ring 32 in the direction of rotation 28 is approximately half the rotational speed of the tools 33 in the radially outer region.
  • the design of the liquid addition and mixing tools 33 can also be in terms of the liquid flow as described and described in DE-A-24 38 818 (corresponding to US-A-4 006 887).
  • the wetting zone b is followed by a post-mixing zone c which extends to the outlet nozzle 23, that is to say approximately to the axial end of the interior 21.
  • Mixing tools 38 are arranged in this post-mixing zone c, the outer structure of which is the same as that of the tools 33 can, but are no longer used for hydration.
  • approximately hook-shaped mixing tools 39 can also be attached, which have a cylindrical tubular, radially extending section 40 and a tapering hook section 41 that leads in the direction of rotation 28 and is bent relative to the section 40 and extends close to the inner wall 31 .
  • These tools 39 can be designed in detail, for example, as is shown and described in DE-A-27 31 767 (corresponding to US-C-4 183 676).
  • the hook-shaped mixing tools 39 can also be replaced by other mixing tools, in particular those which exert an increased axial impulse or a deceleration on the material 29 by changing the angle of attack.
  • mixing tools are known for example from DE-C-20 57 594 (corresponding to US-A-3 734 471).
  • a plurality of — in the present case four — cutting devices 44 are arranged in a common radial plane 43 to the central longitudinal axis 2. As can be seen in FIG. 4, they are each arranged at equal angular intervals, for example 90 °, and offset because of the separation of the housing 1 in a horizontal plane to this plane.
  • Each cutting device 44 has an electric motor 45 which is screwed to a holder 46 which is attached to the housing 1 and passes through it.
  • the holder 46 is penetrated by a knife shaft 47 driven by the electric motor 45, which is directed radially into the interior 21.
  • the axes 48 of the knife shafts 47 thus lie in the radial plane 43 and intersect the axis 2.
  • a plurality of knives 49, 50 are attached to each knife shaft 47 at an axial distance - based on the axes 48.
  • the knives 49 are identical to one another; only the knives 50 directly adjacent to the inner wall 31 have wipers 51 bent toward the inner wall 31, by means of which material 29 which may settle between this knife 50 and the inner wall 31 is thrown back into the material ring 32.
  • the axial extent e of knives 49, 50 corresponds approximately to the thickness f of the material ring 32.
  • the diameter g of the knives 49 and 50 is only slightly smaller than the distance h between the mixing tools 39 which are axially adjacent to one another in this area 27 can cause the material 29 conveyed as the material ring 32 to remain longer in the area of the cutting devices 44, in other words by exerting an impulse acting against the conveying direction 27 on the material 29.
  • the measures described ensure that all not very small material particles inevitably pass through a knife 49 or 50 at least once.
  • the knife shafts are driven at a speed such that the peripheral speed on the outer diameter of the knives 49 and 50 is approximately 10 to 40 m / s.
  • the diameter g of the knives 49.50 is approximately 50 to 250 mm, depending on the size of the mixer, ie depending on the diameter d of the interior 21 of the housing 1.
  • the mixing tools 25 and 39 are designed and set in relation to the axial conveying direction 27 that, taking into account the speed of the mixer 13, an axial feed rate of the material in the mixer between 0.02 m / s and 0.2 m / s is achieved.
  • a thickness f of the material ring 32 of 30 to 120 mm is used.
  • the axial extent e of the knives 49, 50 in the direction of the axes 48 should be between 40 and 130 mm, so that there can be no material particles in the radially inner region of the material ring 32 that are not separated by at least one knife 49 or 50 can be detected.
  • the ratio of the thickness f of the material ring 32 to the diameter d of the housing 1 is 0.06 ⁇ f / d ⁇ 0.24.
  • FIG. 5 shows the shape of the knives, only the knife 50 adjacent to the inner wall 31 being shown. Starting from a hub 52, this has two cutting edges 54 leading in the direction of rotation 53 of the cutting devices 44. In the case of the knives 50, the stripper 51 is formed in each case in the region of the rear edge 55 lagging in the direction of rotation 53 by bending the flat knife 50.
  • the knives 49 look exactly the same in principle; they only have no wipers.
  • Materials 29 that tend to agglomerate are preferably wetted with liquid binder in the mixer. These agglomerates formed in the wetting zone b after the supply of the binder are completely dissolved by the cutting devices 44.
  • paper fibers can be wetted with glue, which are then used to manufacture plasterboard.
  • other materials that agglomerate after wetting can be wetted with a liquid as part of a so-called material ring mixture.
