Definitions

  • the present invention relates to a method for mixing, a conditioner and a paddle rail according to the independent claims.
  • a mixer which consists essentially of a cylindrical housing and has an inlet at one end and an outlet at the other end.
  • a mixer shaft is arranged in the cylindrical housing and has a plurality of paddles for mixing the product introduced into the mixer.
  • the mixer shaft is operated with the outlet closed in an initial phase of operation in such a way that the material to be mixed accumulates in the area of the closed outlet.
  • the mixer shaft is operated in the opposite direction, so that the material to be mixed is again mixed, conditioned and conveyed towards the inlet.
  • the mixer shaft is driven again in the transport direction and the outlet is opened.
  • Such a method is problematic because the increased back pressure cannot ensure that the entire material is mixed and conditioned evenly becomes.
  • the mixer and the material to be mixed are undesirably loaded with pressure.
  • the U.S. 5,580,170 A describes a mixer with a mixer shaft with paddles that are wedge-shaped in cross section.
  • the paddles are arranged in such a way that when the mixer shaft rotates, depending on the paddle type, the product is conveyed in the direction of the outlet or the inlet, which is intended to promote mixing.
  • JP 2004 129519 A discloses a conditioner and a method for mixing a product to be conditioned in a conditioner, comprising the steps of partially filling the conditioner with the product rotating a mixer shaft of the conditioner in a first direction of rotation, so that at least one paddle arranged on the mixer shaft essentially no conveying of the product in the initial area in a direction parallel to the mixer shaft, - rotating the mixer shaft in a second direction of rotation so that the at least one paddle causes the product to be conveyed in a direction parallel to the mixer shaft, the product being conveyed by the conditioner above the Initial area adjacent section of the conditioner is conveyed to the outlet of the conditioner.
  • a method for mixing and a conditioner should be made available, which enable a loss-free start-up, i.e. that the disposal or recycling of the product becomes unnecessary when the mixer is started up.
  • mixer is understood to mean both a mixer for mixing different materials and a conditioner.
  • a paddle for a mixer comprises a flat element with a work surface and a rear surface. When used as intended, the paddle is arranged essentially on a plane perpendicular to an axis of rotation of a mixer shaft.
  • the paddle has a fastening means for fastening the paddle to the mixer shaft.
  • the working surface is inclined by a working angle on one side and the rear surface by a back angle on the other side of the plane perpendicular to the axis of rotation of the mixer shaft. The back angle is smaller than the working angle.
  • the back angle of the back surface is smaller than the working angle of the work surface ensures that when the paddle or mixer shaft is turned in the direction of the converging work and back surface, a material to be mixed is not only mixed by the paddle but also by the work surface away further to an outlet.
  • the inclination of the working surface to the rear surface enables the paddle to have a cutting edge on its front edge in the direction of rotation, which can be moved with little force through the material to be mixed.
  • the back angle of the back surface can be equal to the working angle of the work surface. This is particularly advantageous if an alignment of the paddle is adjustable so that the back angle or working angle can be changed.
  • the work surface and / or the rear surface can also be designed as a curved surface.
  • the corresponding working angle and back angle are then understood to be the angle between the vertical plane and an imaginary line through the end points of the corresponding surface in a cross section of the paddle. The same applies to a paddle, which is formed from a folded sheet metal.
  • the back angle can be greater than or equal to 0 °, preferably exactly 0 °. Because the back angle is greater than or equal to 0 °, when the mixer shaft rotates backwards, the product to be mixed is essentially not conveyed backwards, but only mixed.
  • a backward rotation is understood here and in the following to mean a rotation in which the paddle does not move in the direction of the cutting edge but in the opposite direction. Accordingly, when starting a mixer, for example, the mixer shaft can initially be rotated backwards so that the material filled into the mixer is only mixed and, if necessary, conditioned, but not conveyed in a direction parallel to the mixer shaft.
  • the sum of the working angle and the back angle can be between 4 ° and 50 °, preferably between 6 ° and 30 °, particularly preferably between 7 ° and 15 °. It has been shown that such an angle between the working surface and the rear surface represents an optimum both for conveying the product to be mixed and for mixing, in particular when the mixer shaft is rotated backwards.
  • the paddle can have a cutting edge or a cutting surface which, when used as intended, extends from an area adjacent to the mixer shaft to an essentially outermost dimension of the paddle.
  • a cutting edge is understood to mean that edge at which the working surface and the rear surface intersect. Such a cutting edge does not necessarily have to be sharp-edged but can also have a certain radius or be truncated so that a cutting surface is formed. It is also conceivable that the cutting edge, or possibly the cutting surface, in the area of the paddle, which is close to the mixer shaft, is made wider or narrower than in the area of the outermost dimension of the paddle. The fact that the cutting edge or cutting surface extends to the outermost dimension of the paddle ensures that the paddle can be guided through the material to be mixed with as little effort as possible.
  • a mixing surface can lie opposite the cutting edge which, when used as intended, extends from an area adjacent to the mixer shaft to an essentially outermost dimension of the paddle.
  • Such a mixing surface brings about an optimal mixing of the material to be mixed, especially when the mixer shaft rotates backwards.
  • Such a mixing surface has increased resistance when the mixer shaft is rotated backwards when passing through the material to be mixed, on the other hand it enables optimal mixing.
  • the cutting edge and / or the mixing surface can be arranged essentially radially with respect to an axis of rotation of the mixer shaft. Such a radial alignment of the cutting edge and / or the mixing surface ensures that the working surface in the outermost end of the paddle is made wider and accordingly develops a greater conveying effect and / or mixing effect.
  • the mixing surface with the rear surface can include a mixing angle between 40 ° and 86 °, preferably between 60 ° and 84 °, particularly preferably between 75 ° and 83 °.
  • a mixing surface which has a slight inclination with respect to an axis of rotation of a mixing shaft, reduces the resistance when the paddle is guided through the product to be mixed when the mixer shaft rotates backwards.
  • the paddle can be formed from a square profile with a welded sheet metal angled in a V-shape in cross section.
  • the tip of the V-shaped plate forms the cutting edge, while the mixing surface is formed by a surface of the square profile opposite the cutting edge.
  • two sheet metal plates can alternatively be connected to one another at an angle. The advantage here is that standard components can be used.
  • the paddle can be designed as a simple guide plate, which, however, is rotatably mounted so that the working angle and back angle can be adjusted. In this way, depending on the direction of rotation, the paddle can be aligned in such a way that conveyance and / or mixing takes place.
  • the paddle from a flexible material and to arrange it in such a way that the paddle is essentially rigid when it is moved in the direction of rotation and causes conveyance, while when it is turned backwards the paddle is flexible and deformed by the product to be mixed and consequently no promotion but only a mixture.
  • Such a mode of operation can also be achieved in that, instead of the flexible material, the paddle is articulated to the mixer shaft in such a way that it is held in a working position by the product to be mixed when it moves in the direction of rotation and causes a conveyance, while with a Reverse rotation the paddle is swiveled out of the working position by the product to be mixed and consequently no conveyance but only a mixture effects.
  • the articulation can take place radially, tangentially or in any orientation with respect to the mixer shaft. It can also be provided that stop elements are present which limit the pivoting movement of the paddle, the limitation being more preferably adjustable.
  • paddles made of a rubber-like material can be used here, which function like a dough scraper.
  • the paddle can also at least partially consist of articulated or rotatably mounted elements in the manner of a blind, which are adjusted in their position depending on the direction of rotation in order to effect a conveyance or mixing.
  • the paddle can furthermore have at least partially pneumatically or hydraulically actuated areas which enable the working angle and / or the back angle to be changed.
  • the paddle can also be formed entirely from an inflatable element.
  • the paddle can have an opening extending from the working surface to the rear surface. Such an opening through the work or rear surface allows the product to be mixed to flow through, so that optimal mixing takes place.
  • the paddle can alternatively be formed from two elongated elements which are arranged radially on the mixer shaft and with one another at their end remote from the shaft arc-shaped connecting element are connected.
  • the connecting element can also serve as a stripper.
  • the opening can also be provided with rotatable and / or foldable elements, which open the opening only in a certain direction of rotation (direction of rotation or reverse rotation).
  • the paddle can also be formed as a brush, i.e. from a plurality of bristles or bristle-like elements, preferably arranged radially with respect to the mixer shaft.
  • a paddle rail for a mixer comprises a paddle holder and one or more paddles as described above. Such a paddle rail allows a simple assembly of several paddles at the same time on a mixer shaft of a mixer.
  • the paddle holder can have receiving positions for receiving the fastening means of the paddles.
  • Such receiving positions are, for example, simple bores into which a correspondingly configured fastening means of the paddle can be inserted.
  • the paddles are welded in the paddle holder.
  • the fastening is ensured by means of a press fit or by means of a screw connection.
  • the paddle rail can have a plurality of fastening means for fastening the paddle rail to a mixer shaft.
  • the paddle rail can be screwed onto the mixer shaft.
  • the fastening means would preferably be through bores through which the paddle rail can be fastened to the mixer shaft by means of a corresponding screw.
  • the paddle rail engages in corresponding latching hooks of the mixer shaft and is only secured with a securing means, for example in the form of a pin or a screw.
  • a simple detachable fastening allows in particular a quick replacement of worn paddle rails or worn paddles.
  • different paddle rails can be used depending on the product to be mixed and can be exchanged quickly.
  • the paddle holder is preferably designed as a profile with a U-shaped cross section and is dimensioned in such a way that two paddle holders can encompass the mixer shaft.
  • the mixer shaft can have a substantially square cross-section. Both paddle holders, when connected to one another, also form an essentially quadrangular profile arrangement with an interior, the dimensions of which essentially correspond to the outer dimensions of the mixer shaft.
  • the mixer shaft can be designed, for example, as a spline or spline shaft. A frictional connection with the mixer shaft is also conceivable.
  • a stripper for stripping a material to be mixed when used as intended can be arranged from a housing wall of a mixer.
  • different strippers can be used so that a distance between the stripper and the housing wall of the mixer can be individually adjusted.
  • the wiper can have the shape of a ring segment.
  • the stripper can each have a connecting means at its ends, which are arranged in the direction of rotation when used as intended, with which the stripper of a paddle with the Stripper of a following and / or preceding paddle in the direction of rotation can be connected. Because the strippers of the individual paddles can be connected to one another, the strippers can be designed in a correspondingly filigree manner without, however, losing the required stability.
  • the strippers can be designed as a separate component for retrofitting and, in particular, have connecting means which simultaneously serve both to connect the strippers to the paddle and to connect the strippers to one another. This creates a more cost-effective and easily retrofittable alternative.
  • a mixer shaft of a mixer has a plurality of paddles or a plurality of paddle rails, as described above, at least in a starting area of the mixer shaft. Accordingly, such a mixer shaft is suitable for simultaneously conveying and mixing the product to be mixed in one direction of rotation, while the mixer shaft merely mixes the product to be mixed in the other direction of rotation.
  • the paddles which are arranged one after the other in the direction of rotation when used as intended, can be connected to one another by means of straps.
  • Such strippers serve, on the one hand, to strip off any material adhering to the housing wall of the mixer and, on the other hand, the strippers increase the stability of the individual paddles and the strippers with one another.
  • the stripper can alternatively be designed as a wire rope which is fastened or guided along the mixer shaft in corresponding receiving sections of the paddles. This also creates a simpler and cheaper variant for forming a stripper.
  • the pitch (pitch) of the helical structure which is formed by the interconnected strippers, can be selected as required. It is thus conceivable, for example, that not every paddle arranged in the direction of rotation is connected to the following or preceding paddle by means of stripes, so that a greater slope is created. Furthermore, the strippers can be connected to one another in such a way that several helical structures are created.
  • the helical structure prefferably has a direction of rotation opposite to the direction of rotation of the paddles. This means that paddles arranged in the direction of rotation are arranged, for example, along an imaginary right-hand helix, while the helical structure is left-hand.
  • the paddles or the paddle rails can only be arranged in the starting area of the mixer shaft.
  • Such a mixer shaft is accordingly equipped with different conveying and mixing means. Because the correspondingly shaped paddles are only arranged in the starting area, various mixing and conveying operations can be implemented with one and the same mixer shaft. In particular, however, it is still possible, when starting up the mixer, to keep the product to be mixed in the starting area of the mixer shaft until the required mixing is ensured.
  • the paddles and the paddle rail can also be arranged as desired along the mixer shaft.
  • a mixer according to the invention has a mixer shaft as described above. Such a mixer enables problem-free start-up without the product required to start up the mixer being disposed of or recycled.
  • essentially no conveyance of the product is effected when the mixer shaft rotates in the first direction of rotation.
  • “essentially no conveyance” means that the product remains in the area and is possibly circulated there in which the paddles are arranged.
  • this does not rule out that the product is conveyed back and forth within the area, for example in a direction parallel to the mixer shaft, without, however, overall conveying of product in the direction of an outlet of the mixer and out of the area in which the paddles are arranged takes place out when the mixer shaft rotates in the first direction of rotation.
  • other elements are attached to the mixer shaft which either cause no conveyance or reverse conveyance, which means conveying in the direction of the inlet of the mixer.
  • the mixer can be arranged with a slope. This means, for example, that the mixer shaft is not arranged essentially horizontally but inclined slightly downwards.
  • the starting area of the mixer shaft is arranged lower than an outlet area, so that when the mixer is started up, gravity is used to hold the product to be mixed in the starting area of the mixer.
  • an outlet area can be arranged lower than the initial area become.
  • paddles or paddle-like elements can be arranged on the inner surface of the shell of the mixer in order to further improve the mixing.
  • damming means can be arranged in the mixer, which hold the product to be mixed in the starting area of the mixer shaft when starting up.
  • One possible embodiment of the damming means is a pneumatic damming disk which is arranged circumferentially on the inner surface of the jacket of the mixer and can be inflated if necessary.
  • a baffle plate in the manner of an iris diaphragm can also be implemented.
  • the stowage means can also be arranged on the mixer shaft, for example as hinged elements which can be opened and closed like an umbrella.
  • CFRP and / or GFRP carbon fiber reinforced and / or glass fiber reinforced plastics
  • plastics as well as ceramic materials are possible.
  • the steps of rotating in the first direction of rotation and in the second direction of rotation can be repeated several times. By changing the direction of rotation several times, it is even possible to influence the mixing or conditioning while the mixer is in operation.
  • a preconditioning or premixing can be carried out upstream of the process according to the invention.
  • the mixing area along the shaft can be changed by changing the orientation of the paddles.
  • the mixing area can be made shorter or longer depending on the throughput.
  • Another alternative or additional possibility is to mix and heat the product to be mixed with compressed air and / or steam (additionally) while the mixer shaft is stationary or rotating.
  • the nozzles for introducing compressed air and / or steam can be both on the inner surface of the Shell of the mixer as well as be arranged on the mixer shaft.
  • rotating nozzles which are set in rotation by the outflow of compressed air and / or steam, can be provided.

  • the paddles 30 are each connected to one another with the corresponding strippers 40.
  • the individual paddles 30 are each arranged on a paddle holder 21.
  • the paddles 30, the strippers 40 and the paddle holder 21 together form a paddle rail 20, which can easily be exchanged if necessary.
  • the mixer shaft 10 rotates about the axis of rotation 11.
  • the Figures 4a and 4b show a mixer 1 according to the invention, the Figure 4a a view and the Figure 4b shows a perspective view of the mixer 1 with an open housing wall 2.
  • the mixer 1 has an inlet 15 and an outlet 16.
  • the mixer shaft 10 arranged in the interior of the mixer 1 is provided with wedge-shaped paddles 30, as described above. These wedge-shaped paddles 30 ensure that in a direction of rotation R (see Figure 1a ) the product filled into the mixer 1 is mixed and conveyed, while the product is merely mixed when the mixer shaft 10 rotates in the opposite direction R '.
  • the individual paddles 30 are each connected to one another via strippers 40.
  • the paddles 30 are each arranged on a paddle holder 21.
  • the strippers 40 have connecting means 41 at their ends, which enable the connection to a subsequent stripper 40.
  • the wedge-shaped paddles 30 are on the side opposite to the direction of rotation R (see Figure 1a ) have a mixing surface 38, while a cutting edge 37 is arranged on the other side.
  • Such a mixer 1 can now, for example, at least partially when starting up with a product to be mixed via the inlet 15 be filled.
  • the mixer shaft 10 can then be rotated in such a way that the mixing surfaces 38 of the paddles 30 mix the product to be mixed. Only when the product to be mixed has reached the desired consistency, for example by adding steam and / or by heating, can the direction of rotation of the mixer shaft 10 be changed so that the individual paddles 30 with their work surface 33 mix the product to be mixed and at the same time in Promote direction to outlet 16. If necessary, the direction of rotation of the mixer shaft 10 can be changed again if the product to be mixed and conditioned does not yet meet the required conditions.
