Definitions

  • the invention relates to a mixing dryer and / or reactor according to the preamble of claim 1.
  • cone screw mixers which are formed in that a conically shaped mixing screw driven in a cone-shaped product space is arranged to rotate
  • a conical screw mixer consists of a conical jacket, which has a lower, central central outlet and from a top floor closing off the product space, at which different inlet and other openings are arranged.
  • the mixing screw in its radially outer region must have a substantial radial distance from the inner wall of the cone shell, wherein this distance is about 20 mm, depending on the length of the mixing screw.
  • the high design is undesirable for installations in a chemical plant and leads to unnecessarily high construction costs, because it is common practice to arrange the individual devices in chemical production plants by the tube.
  • the reaction vessels are arranged, the outlet is connected to a centrifuge, which centrifuges are arranged on the first floor of the production plant and the outlet of the centrifuge in turn runs in a arranged on the ground floor mixing dryer. If such mixing dryers are designed as undesirably high cone screw mixing dryers, there is the disadvantage that construction volume is lost and said three-level arrangement of a chemical plant is necessary.
  • ball mixers It is also known to use so-called ball mixers. It is full-bodied mixing body, in the interior of which the product is mixed, because the ball dryer is penetrated by a mixing shaft, which is rotatably connected to mixing blades, which achieve a thorough mixing of the product.
  • the invention is based on the problem of proposing a more cost-effective mixer dryer with significantly lower overall height, lower production costs and improved product drying and mixing degree.
  • the invention is characterized by the features of independent claim 1.
  • Claim 1 provides as essential features that the mixing dryer according to the invention in its upper region has a truncated cone shortened compared to the prior art and in its lower region a curved bottom, such as. spherical ball section bottom or a basket bottom or dished bottom.
  • Claim 2 provides as essential features that at least two axially spaced-apart mixing elements are arranged radially asymmetrically on the agitator shaft of the agitator, each having at least two differently long armature blades.
  • This is according to claim 2 has the advantage that now in this outlet area, which is in particular designed as a ball bottom, an excellent mixing is given because in this outlet area (ball bottom) a special floor mixer can be arranged very close to the wall with low tolerance at the Along the wall can run without the risk - which was given the conical screw mixer - that this mixing screw escapes into this area due to acting transverse torques and the mixing screw helix run on the wall side.
  • the invention thus consists in that one essentially uses a shortened conical jacket in the upper region and in the lower region uses in particular a spherical bottom, and this results in a bell shape of a novel mixing dryer, which is therefore referred to in the context of the present invention as a "bell dryer" becomes.
  • Characteristic feature of this bell dryer is that the product space has the shape of a bell, namely a spherical bell bottom, which is also referred to below as a ball bottom and an overlying cone sheath, which corresponds in its cone sheath angle the ball shroud angle of the conventional cone screw mixer.
  • the bell dryer according to the invention has a flange height of 78 cm for the same diameter and for the same product volume. It is therefore a 40% reduced overall height of the entire mixer dryer with the same volume and the same diameter. This is a decisive advantage that the bell dryer according to the invention has over the prior art. Its height is thus reduced compared to a similar conical screw mixer by 40%. Due to the fact that in the lower area - approximately in the range of one third of the total height of the mixer dryer a spherical bottom is applied, resulting in lower manufacturing tolerances, because such a spherical bottom can be made very easily. It is dimensionally stable and can be made very accurately, resulting in better roundness. For this reason, it is - as previously mentioned - possible to use the soil mixer used in this area with a small radial distance of z. B. 5 mm to the inner wall of the ball bottom run.
  • the bell dryer is formed vertically aligned and has a central lower outlet opening.
  • the mixing screw occupies an angle to the vertical and z. B. has an angle in the range of 5 to 15 degrees. Then it is thus provided that the entire container is formed inclined in this range of 5 to 15 degrees, which leads to the advantage that the lower, bottom-side spout can now be aligned exactly in the vertical, so that the product due to gravity exactly in the Vertical can be discharged. A lateral discharge of the product is therefore not given, and therefore there is no risk of caking of the product in the outlet area.
  • the bottom-side mixer (bottom mixer) has two anchor vanes of different lengths.
  • anchor bucket is therefore chosen because the blades approximately correspond to the shape of an anchor and are also formed differently long. This results in obliquely positioned product space and inclined floor mixer with inclined mixing shaft, the product is first detected by the lower lower bottom blade and conveyed in the direction obliquely upward and there experiences a quiet zone, namely where the radially outer length of the armature blade ceases. The product remains there in the product space and, after a short rotation of the bottom-side mixing element, is caught by the longer armature blade and conveyed further upwards. Therefore, there is an intermittent mixing of the product, because the product temporarily remains in the product space due to the differently long trained mixing blades, to then be further mixed in the product space into it.
  • this product is caught by an organ arranged approximately in the middle region of the product space, this mixing element once again having unevenly long blade paddles, which in turn perform the same mixing effect, ie. H. when conveying the product by the shorter paddle paddle obliquely upward initially define a rest zone for the product at the radially outer boundary of the shorter paddle paddle, after which then takes the half-turn the longer paddle paddle the product remaining there and further promotes obliquely upwards.
  • Another advantage is that due to the selected spherical shape of the spherical base now for the first time there is the advantage that with the same material use (wall thickness of the bell dryer compared to a conical screw mixer) a significantly improved Beulstabiltician, distortion resistance and dimensional stability is guaranteed. Due to this fact, it is now possible for the first time to operate such a bell dryer with overpressure, which is possible with conventional cone screw mixers only with increased use of material and deteriorated efficiency.
  • FIG. 1 shows the main advantages of the present invention.
  • a conical screw mixer 30 is shown with the same product volume and at the same container diameter 28 has a much greater height, as can be seen on the Konusmantel arrest 26.
  • the Konusmantel arrest 26 is defined by the fact that it corresponds to the height of the product space to the boundary of the flange seal 23.
  • a comparison with the FIG. 1 and the novel bell dryer 1 shows that the bell shell height 27 used there is reduced by 30% compared to the cone shell height 26.
  • the product space also has a product amount of about 500 liters. The amount of product is in this case filled as far as the boundary line 22.
  • a topsoil 2 is arranged in the conical worm mixer and a top stirrer flange, through which an agitator shaft, not shown, extends through.
  • the cone sheath angle 24 of the cone sheath 38 corresponds exactly to the cone sheath angle 24 of the bell dryer 1 and has approximately the value of 45 degrees.
  • a ball bottom 34 is now attached to the cone shell 38 in this area and connected in one piece with the material. It can, for. B. take place a direct welding. Also, of course, releasable connection means (e.g., hinged hinges) may also be placed in this area. This leads to the fact that you can convert a conventional conical screw mixer at any time by cutting the conical surface 38 in the region of the third height 29 and the ball bottom 34 attaches, resulting in total to the bell shape of said bell dryer 1.
  • a pivotally hinged to the cone sheath 38 ball bottom 34 is that a good inspectability of the agitator and the outlet can be done in the lower area, in contrast to conventional conical screw mixers 30.
  • Another advantage is that by a hinged from the cone sheath 38 ball bottom 34, the agitator of can be introduced below the open lower end face of the cone shell 38 in the bell dryer 1, which then the expensive flange connection between the upper floor 2 and cone sheath 38 can be omitted.
  • the ball bottom height 33 is significantly reduced compared to the third height 29, because by this reduction the actual Savings the height is achieved. This is indicated by the dimension line 32 in FIG. 1 displayed.
  • the mixing screw 25 of a conical screw mixer 30 can also be used in a bell dryer 1 according to the invention.
  • the invention is not limited to this, because the invention is based on the FIGS. 2 to 4 describes other mixing organs, which should enjoy protection in their own right but also in combination with the new spherical bottom 34.
  • FIG. 2 Further details of the bell dryer 1 according to the invention are shown.
  • the agitator drive 9 drives a stirring shaft 11, which is inserted through a bearing and sealing lantern 10 in the region of the upper bottom 2 in the product space 48.
  • a stirring shaft 11 which is inserted through a bearing and sealing lantern 10 in the region of the upper bottom 2 in the product space 48.
  • an inlet pipe 3 is arranged for the entry of solid and also a manhole 4 for the inspection of the product space 48th
  • heating stub 5, 6 are arranged for the heating of the upper floor 2.
  • the conical jacket 38 is heated by the heating stub 7, 8 and incidentally has an outer insulating jacket 12 on.
  • Two mixing elements 13, 14 arranged vertically one above the other are provided, wherein it is important that the total of the bell dryer 1 is inclined and in this case has the mixing axis 35 at an angle of inclination 37 in the range of 5 to 25 ° in the direction of the vertical 36.
  • the lower mixing element is designed as a bottom mixer 14 and has two unequal length armature vanes 15, 16.
  • the agitator shaft 11 is rotatably supported in a lower thrust bearing 17.
  • the outlet opening 18 has a small angle in the direction of the vertical 36th
  • the outlet opening 18 is controlled by an outlet valve 20, which is associated with a valve drive 21.
  • the bell shape of the bell dryer 1 thus results from the fact that along the dimension line 31 (FIG. A) the lower part of a conical screw mixer 30 is cut off and is replaced by a ball bottom 34 (FIG. Fig. 1 . 2 . 4 ) is replaced.
  • FIG. 3 the details of the two mixing organs are shown in more detail.
  • the upper mixing member 13 consists of two unequal length blade paddles 39, 40 which are arranged symmetrically at the same angle to the mixing axis 35 and in this case consist of two inclined paddle blades 39, 40 which are non-rotatably connected via connecting webs 41 of the agitator shaft 11.
  • bottom mixer 14 An identical mixing process also takes place with the bottom-side mixing element (bottom mixer 14). This consists - as mentioned - from two unequal length anchor blades 15, 16, the in FIG. 3 are shown again in plan view. Again, the product of the lowest lowest point of the ball bottom 34th taken, wherein each anchor blade only has a distance from the bottom of the ball of about 5 mm, is taken up by the armature blade in the direction of arrow 42 and in the direction of the radially outer inclined obliquely curved in the circumferential direction anchor vanes 15, 16.
