Definitions

  • the invention relates to a batch mixer with a preferably horizontal mixing shaft in an approximately drum-shaped housing, the lower wall area of which is designed as at least one opening flap for emptying, the opening angle being greater than the angle of repose of the material to be mixed and the opening flap extending from the front to the front of the housing,
  • Such a batch mixer has been proposed in the main application and has the considerable advantage with regard to the mixing function and above all with regard to its emptying that cleaning after emptying the dry material to be mixed is not necessary. This is achieved by the large opening angle, which exceeds the angle of repose of dry bulk material, so that no mixture can remain within the open housing of this mixer. A different mixture can therefore be processed in the mixer after the opening has been closed without this being adversely affected or influenced by the preceding mixture. From FR-PS 1 329 058 a drum-shaped mixer with a polygonal cross-section and with two jaw-shaped slide valves that can be opened in the shape of a mouth is already known, the entire mixer housing being rotated for the mixture.
  • the mussel slide For their opening movement, the mussel slide must first be moved vertically downwards in order to be released from their sealing performance before they can then be folded sideways. On the one hand, this results in complex mechanics and, on the other hand, there is the risk that in this mixing drum, in which the opening angle is significantly smaller than the slope angle of dry mix, such material remains and, if necessary, even comes against the seal when the slide is closed.
  • upstanding strips are provided on the inside of the slides, which should be pressed against the seal. Together with the outside of the slider, these strips form a single space in which mixed material can remain.
  • Such a mixer is not suitable as a batch mixer for changing mixtures.
  • the solution to this problem consists essentially in that at least the upper horizontal narrow side of the narrow flap located in the articulation area of the pivotable opening flap is formed obliquely in cross section and encloses an acute angle between itself and the outside of the opening flap that the housing opening has a matching counter slope as an attachment for the has sloping narrow side of the flap when the opening flap is closed and that in the region of this narrow side of the housing at a point remote from the interior of the housing there is a seal that is operatively connected to the closed opening flap.
  • the oblique design of the upper horizontal narrow side of the opening flap ensures that when opening the flap this narrow side does not get into a horizontal, but rather a corresponding oblique position, so that no material can remain on it, which prevents the tight fitting when the flap is closed could.
  • such an oblique joint has an overall better sealing effect, which is further improved and supported by the sealing strip.
  • the sealing strip in the counter is inclined of the mixer housing, so that the oblique narrow side of the opening flap is in the closed position directly against this seal.
  • a particularly favorable embodiment of the invention in which a seal can also be achieved if the inclined surface on the narrow side of the flap should be worn out by draining material, can consist in that the sealing strip is arranged or embedded on the outside of the housing adjacent to the counter slope and on the outside of the flap a pressure and counter bar is attached to this seal in the closed position.
  • a corresponding sealing strip in particular, to be embedded in a groove both on the oblique narrow side and on the outside of the housing.
  • the sealing strip is located on the "shadow side" of the housing with respect to the mix, so that it is not acted upon by the mix when the mix is discharged.
  • the counter bar can be exchangeably and adjustably attached, in particular releasably, to the outside of the flap. This counter bar does not hinder the opening process if the pivot axis for the flap is arranged outside the housing and above the sealing joint. During the pivoting movement, the surfaces lying against one another then detach from one another before they are also pivoted away from one another. Conversely, when they close, they lay down practically without each other Friction against each other.
  • sealing strip is incorporated next to the inclined surface of the flap and the flap with the acute-angled bevel on the outside preferably carries a counter strip for engaging the sealing strip.
  • This counter bar in particular is exposed to a certain material closure when the flap is opened, so that it is advantageous if it can be replaced.
  • the narrow sides of the flap can in turn be designed obliquely in such a way that the outside of the flap forms an acute angle with the narrow side, and on the container housing, the end wall can have a matching oblique mating surface on the circumference, which is pointed between the outside and the oblique surface Angle.
  • a sealing strip arranged in the circumferential direction can be fastened between the inclined surface and the outer housing wall, and the flaps can preferably have interchangeable counter strips on their outer sides, which in the closed position bear against these sealing strips running in the circumferential direction.
  • sealing strips are arranged around the housing opening in places that are not touched by the outflowing material, preferably embedded, which are overlapped by counter strips on the flap (s) in the closed position and below in their receiving groove or the like seat directed sealing pressure are set.
  • the seals can also be interchangeably clamped in grooves.
  • the Flap shape is adjustable, in particular in the area of the sealing strips in the sense of a largely uniform sealing effect. This can compensate for the loads on the flap, which could lead to loosening of the seal seat in certain areas.
  • stiffening arms are arranged next to one another along the length of the flap, which have fastening points between them and the outside of the flap for spacer plates that can be used there.
  • more or less spacer plates can be placed on the individual arms in order to have a secure system everywhere, even with heavy loads or deformation.
  • the support arms for the flap have an angular or T-shaped cross-sectional profile, an angled leg or the T-crosspiece engaging the flap and allowing the spacer plates to be inserted between them and the flap.
  • a batch mixer designated as a whole has a horizontal mixing shaft 2 which is acted upon by a coaxial drive motor 3 and is accommodated in a drum-shaped housing 4 according to FIG. 2.
  • the lower wall area of this housing 4 can be opened for removal, two opening flaps 5 being wing-like to one another and pivotable away from one another.
  • These opening flaps 5 practically form the lower wall area of the housing 4. They are so large that the opening angle of the housing opening is greater than the slope angle of dry mix. 1, the opening flaps 5 run from the front to the front of the housing 4. In this way, complete emptying of a mixer is possible without additional cleaning measures, because when the opening flaps 5 are opened, the dry mix from the mixer, for example, initially falls into an intermediate funnel 6 can, without projections or the like. On which residues of mixed material could remain.
  • the swiveling opening flap 5 are located in the joint area or in the region of the pivot axis 7 according to FIG. 3 upper horizontal narrow flap sides 8 are formed obliquely in cross section, an acute angle being formed between the narrow side 8 and the outer side 9 of the opening flap 5, which can be, for example, in the order of 55 °.
  • the housing opening has a matching counter bevel 10 as a contact surface for the sloping flap narrow side 8 when the opening flap 5 is closed, as shown in FIG. 3.
  • a seal 11 that is operatively connected to the closed opening flap 5 is arranged.
  • the seal 11, which is designed as a sealing strip, could be embedded in the counter-bevels 10 of the mixer housing 4, so that the oblique narrow side 8 would contact the seal 11 in the closed position. With such an arrangement, the seal 11 is already on a "shadow side" opposite the outflowing mix.
  • the sealing strip 11 is arranged and embedded in a groove 12 a and on the outside 9 of the opening flap 5, a pressure and counter strip 12 which engages over this seal 11 in the closed position is fastened.
  • This counter bar 12 is detachable and replaceable and also adjustable by means of screws 13.
  • the counter bar 12 can not hinder the opening process of the opening flap 5, since the pivot axis 7 for this flap 5 is arranged outside the housing 4 and above the sealing joint formed by the inclined surfaces 8 and 10 on the one hand and the seal 11 and the counter bar 12.
  • the surfaces lying against one another first detach before they are swiveled away from one another. Conversely, when they close, they lay against each other practically without mutual friction.
  • the opening flaps also have sloping narrow sides 14 in their contact area, and the opening flap 5, the sloping surface 14 of which forms an obtuse angle with the outside 9, has a sealing strip 11 in an area facing away from the mix, which cooperates with the other opening flap and its sealing surface.
  • the sealing strip 11 is incorporated next to the inclined surface 14 of the flap 5 and the flap 5 with the acute-angled inclined surface 14 on its outside
  • Counter bar 12 bears against the sealing bar 11, which in turn is interchangeable and also adjustable by means of screws 13.
  • This counter bar 12 in the contact area of the two opening flaps 5 can be exposed to a certain flow of material when the flaps are opened, so that they may wear out faster, so that it is advantageous if they can be replaced quickly.
  • the seal in the area of the end faces of the mixer 1 is illustrated particularly in FIG. 4.
  • inclined surfaces 16 can be seen which form an acute angle with respect to the outside 17.
  • the opening flaps also have an inclined surface 18 in this area, which runs at an acute angle to their outside, the two inclined surfaces 16 and 18 matching each other in such a way that the closed opening flap 5 is mitred with this end wall region, as is the right part of FIG Fig. 4 illustrates.
  • an outer housing wall section 19 is also provided, which projects downward beyond the flap end faces. This can pass into the funnel 6.
  • Interchangeable mating strips, which bear against these sealing strips 20 in the closed position, can in turn be attached to the flap outer sides.
  • these counter strips running parallel to the end faces are not visible, since they run from the longitudinal section through the counter bar 12 are concealed at the opening area of the two flaps. However, they can be connected directly to this sealing strip 12 on the end faces.
  • sealing strips 11 and 20 are arranged and embedded around the very large housing opening at all points that are not touched by the outflowing material, which overlap with counter strips 12 on the flaps 5 in the closed position and under in their receiving groove 12 or 21 directional seal pressure. These sealing strips can also be replaced if they have aged or their sealing effect is weakening for other reasons. Elaborate labyrinth seals u. The like are avoided. This results in a mixer housing 4, which is dust-tight and maintains its tightness even at high pressures during the mixing process, but nevertheless has a very large outlet opening.
  • the flap shape can be adjusted in particular in the area of the sealing strips 12 and 21 in the sense of a largely uniform sealing effect.
  • stiffening arms 22 are arranged next to one another at a distance from the joint axis 7 over the length of the opening flaps 5. These are connected to the opening flaps 5 in a manner yet to be described and transmit the forces from working cylinders 23 to the flaps, these cylinders 23 each acting on the hinge axis 7 with a lever arm 24 according to FIG. 2.
  • spacer plates 25 that can be used there.
  • spacer plates 25 can be placed on the individual arms 22 in order to compensate for deformations of the opening flaps that occur during production or under load, and a secure system in particular everywhere effect in the sealing area.
  • the support arms 22 can have an angular or T-shaped cross-sectional profile, an angle leg or the T-crosspiece engaging the flap 5 and allowing the spacer plates 25 to be inserted between them and the flap.
  • This is a very simple and practical design for bracing and adapting the flaps to high loads or to compensate for any deformations that may occur.
