Definitions

  • the invention relates to a device for conveying, crushing and mixing of conveyed material with a high solids content, with a cylindrical housing and a shaft stub projecting into the latter, an entry opening opposite the latter and at least one discharge opening provided perpendicularly, approximately perpendicularly or tangentially to the shaft stub axis and on Slats attached to the shaft, reaching to the entry opening.
  • a device for conveying, crushing and mixing of conveyed material with a high solids content with a cylindrical housing and a shaft stub projecting into the latter, an entry opening opposite the latter and at least one discharge opening provided perpendicularly, approximately perpendicularly or tangentially to the shaft stub axis and on Slats attached to the shaft, reaching to the entry opening.
  • a discharge opening provided perpendicularly, approximately perpendicularly or tangentially to the shaft stub axis and on Slats attached to the shaft, reaching to the entry opening.
  • blades
  • Such a device is known from DE-A-26 09 710.
  • the cylindrical housing of this known device has internal teeth which mesh with the correspondingly serrated lamellae.
  • the mixed material exits approximately radially through holes or slots and is directed to the discharge opening.
  • the inner wall of the housing is formed by partially cylindrical ring segments which are wedged together in the operative position.
  • the invention has for its object to increase and improve the screening of the crushed material with the crushing effect.
  • the object is achieved in that, according to the invention, individual rings are at least partially arranged on the inside, the distance between them determines the degree of comminution of the emerging material to be conveyed and that the lamellae or blades have an outer edge adapted to the cross section of the spaced rings.
  • This device is primarily suitable for a pulpy conveyed material containing a fluid; it is less suitable for dry goods.
  • the inner wall of the housing is thus divided into individual rings, between which the material to be conveyed can emerge; the latter is then conveyed to the discharge opening.
  • the rings are used, for example, at a distance of only two millimeters, in some cases only 1 mm, for. B. wedged, so that the comminuted material can emerge not only at a designated point, but at all ring gaps.
  • the material to be conveyed can be fine or coarse; it can be liquid, mushy or dry; however, it must be flowable at least on the discharge side.
  • the rings have a different cross section. This makes it possible to reduce the crushing effect z. B. compared to toothed, intermeshing surfaces and still not affect the sieving purpose brought about by the spacing of the rings.
  • the rings can have different thicknesses.
  • At least one ring is provided with projections directed inwards in the radial direction.
  • These inwardly projecting projections can be rectangular in cross-section and provided with recesses in the axial direction; the cutouts of a ring can also have different sizes.
  • the cutouts can be approximately rectangular.
  • At least one ring preferably has a round, smooth inner surface.
  • At least two fins or blades are provided, they expediently extend in a straight line in the radial direction; the fins or blades can also run in a straight line in the axial direction.
  • the outer edges of the lamellae are meandering.
  • the inner edges of the lamellae or blades and the end face of the stub shaft form a suction cavity which widens like a truncated cone toward the inlet opening and extends at least to half the length of the housing, preferably to two thirds to three quarters of the length of the housing.
  • the crushing effect is increased by the device according to the invention; in addition to this effect, however, the sieving is improved insofar as nd increases 4, can escape as the comminuted material not only in the area of holes of the root of the internal teeth of the housing, but to a certain extent in the sum of the spaces between the individual rings. If, for example, four radially extending straight lamellae or blades are offset by 90 °. Used, the conveying capacity of the device is also increased significantly and, for example, increased by approximately 30% compared to a shredding device with a swash plate and teeth.
  • At least some of the rings are attached to the lamellae or blades and lie opposite the outlet slots; in this way it is achieved that between the opposite surfaces «Grated or shredded conveyed material can exit radially immediately and be pressed to the discharge opening or « extracted.
  • This embodiment can be modified such that rings are arranged next to the rings on the fins or blades, which are arranged on the inside of the housing.
  • the individual z. B. arranged on the inside of the housing rings in a perpendicular to the axial direction plane have different profiles.
  • All rings preferably consist of at least two parts and can be placed on the fins or blades for installation.
  • Spacers can also be arranged between the rings locked on the inside of the housing.
  • the ring units can be installed in such a way that the fins or blades can be pushed into the cylindrical housing together with all the rings. Then the rings on the inside of the housing are locked at the height of the stub shaft and at the height of the entry opening. It is obvious that all of the rings, whether those on the lamellae or blades or those on the inside of the housing, must be connected to the associated parts in a rotationally fixed manner.
  • a total of nine individual rings are held in a rotationally fixed and centered manner via spacers 3, 4 and a feather key 5.
  • Two types of rings are provided, namely five rings 6 and four rings 7, the two ring types having a different clear diameter.
  • An approximately cylindrical cavity is formed between the tube 1 and the outer surface 11 of the rings, but it widens to the side opposite the feather key 5 and finally leads to the opening 2 in the tube.
  • the opening 2 leads to a tangential discharge opening 12 which has a rectangular cross section.
  • the rings 6 each have projections 14 provided with intervals 13 in the circular direction, which have a round inner surface 15 and a recess 16 running in the axial direction.
  • This recess 16 has approximately a rectangular cross section and extends over the full width of the respective rings 6.
  • these recesses 16 running in the axial direction have a different depth, specifically within the ring type 6. The depth can be at the illustrated embodiment vary between one and five millimeters, the width of the recess can be the same.
  • the four rings 7 have a cylindrical inner surface 20 and also distribute rectangular recesses 21; these recesses 21 in the rings also extend over the entire width of the rings and can be rectangular; the depth of the recesses 21 can also vary, for example, between one and five millimeters.
  • a space 22 is provided between the rings 6 and 7, which leads to the approximately cylindrical cavity, so that - as explained in more detail below - the discharged material is pressed out through the spaces between the rings and to the discharge opening 12 hikes.
  • the degree of comminution of the conveyed material emerging from the total of eight spaces 22 is thus determined by these spaces; Since the gaps are the same over the entire housing, a material to be conveyed that is crushed uniformly with the greatest accuracy is fed to the discharge opening.
  • lamellae 30 are attached to the stub shaft 9, each radially offset by 90 ° and also extending in a straight line in the axial direction.
  • the slats 30 each have a meandering outer edge 31, which corresponds to the profile of the spaced individual rings.
  • the inner edge 32 of the individual lamellas opens in the shape of a truncated cone to the discharge opening 33, as a result of which the material to be conveyed entering the suction cavity 34 is thrown or pressed essentially in the radial direction and can exit through the discharge opening 12 after the desired size reduction.
  • the individual rings are moved along the spacers 3 and 4 when inserted and then locked by the key 5.
  • the ring 8 has an internal toothing 36, onto which a ring 37 can be pushed, which holds the individual rings 6 and 7 in the axial direction via a spacer ring 38.
  • the space 22 between the individual rings can be produced, for example, by projections provided on the side surfaces 39 of the respective rings.
  • outer edges of the slats 30 are meandering, another profile, for. B. an approximation to a tooth-shaped profile can be chosen; it is also possible to increase the number of ring types, to increase the distances between the individual rings and also to provide recesses 16 or 21 of different shape in the axial direction instead of the rectangular recesses.
  • the rings 7 have a smooth inner surface, so that no recesses 21 are provided in these rings.
  • the profile of the rings 7 in the illustrated embodiment is approximately T-shaped; Instead of this profile, a rectangular profile can of course also be provided, so that the space 22 for the comminution extends over the entire axial depth of the ring 7.
  • the embodiment described below in connection with FIGS. 3 and 4 is one which is particularly essential and with which a degree of comminution of up to 0.6, if necessary less than 0.4 mm. B. 0.2 mm can be achieved. While the device described in connection with FIGS. 1 and 2 is primarily suitable for pulpy or very viscous materials and essentially dry material to be conveyed can only be crushed with difficulty, the embodiment described below is suitable for much more material to be comminuted, possibly also in the dry state ; the only important thing is that a liquid substance is formed or is present at the discharge opening.
  • FIGS. 3 and 4 While the basic structure of the embodiment shown in FIGS. 3 and 4 is the same as that according to the previous embodiment, four slats 41 are attached to the stub shaft 40; these slats each extend in a straight line in the axial direction and in the radial direction; however, they can also be curved in one or both directions.
  • two types of rings 43 and 44 are provided, the rings 42 in the illustrated embodiment being attached to the slats 41 with a rectangular cross-section, e.g. B. are wedged and the rings 44 are rotatably connected to the inner wall 45 of the housing 46.
  • the rings 44 consist of a wide base 47 and a rectangular projection 48.
  • the rectangular projections 48 are similar to the projections 14 in the embodiment according to FIGS. 1 and 2 and have recesses of different sizes which run in the axial direction.
  • the coarse-grained or very small-sized conveyed material entering the funnel-shaped inlet opening is guided radially outward, if necessary after a previous comminution with a screw conveyor, so that it comes into the edge region of the lamellae.
  • the material to be conveyed is then further comminuted in the slots 50, 51 and 52 between the projections 48 and the lamellae and then passes through the slots 53 and 54 into the annular slot-like cavity 55, from which the finally comminuted material to be conveyed via the annular slot 60 into the Discharge opening 61 is promoted.
  • the grain size of the conveyed material is determined by the distances 53 and 54 between the radial walls of the rings 43 and 44.
  • FIGS. 3 and 4 The embodiment described in connection with FIGS. 3 and 4 is assembled in such a way that the individual ring units 43, 44 are placed alternately on the lamellae connected to the stub shaft 40, namely in that all rings are designed as half rings and thus radially on the Slats can be placed or pushed on.
  • the rings 44 also have the precisely provided spacing - of the order of a few fractions of a millimeter - at least three or more strip-shaped spacers 61 are provided between the rings 44 over the circumference of the two half rings, which are half the depth of the ring slots 55 and thus ensure that the rings 43 wedged onto the slats assume their precisely defined position between the rings 44, which are wedged to the housing wall.
  • the conveyed material to be comminuted can be crushed relatively quickly and to a relatively large extent and conveyed radially outward, so that it can leave the device via the discharge opening 61; a pump may be switched on at the latter to increase the conveying effect.
