  • the invention relates to a mixer, comprising an elongated, substantially cylindrical, upright sleeve, which forms the wall of a mixing chamber, a supply inlet for solid material and a supply inlet for liquid debouching in said mixing chamber, said sleeve accommodating a central mixing shaft coupled to a drive means and bearing blade holders with blades fitted therein.
  • Mixers of this kind are already known and are applied, for example, for continuously mixing a powdered solid matter with a liquid or for granulating powdered products by mixing them with a liquid.
  • the wall of the mixing chamber of these known mixers may become more or less extensively encrusted, which impairs the mixing efficiency.
  • the blade holders are each rotatable through 360 about an axis of rotation which is perpendicular to the mixing shaft and may be fixed in any position by a locking member.
  • the residence time of the material supplied into the mixer can thus be effectively influenced.
  • At least one blade holder block may be mounted upon the mixing shaft, which block bears, distributed over its periphery, a plurality of said blade holders each having slots wherein the end of a blade is detachably lockable by means of a locking member, each blade holder being secured by bolt means to a retaining member which is rotatable through 360 about an axis of rotation perpendicularto the mixing shaft, said retaining member being accommodated in a chamber in the blade holder block and being secured against outward displacement by means ofa collar of the blade holder block, said retaining member being lockable with the aid of said bolt means in each angular position with respect to the blade holder block.
  • the blade holder block may have a cylindrical bore through which the mixing shaft extends, said blade holder block being lockable in each position with respect to said mixing shaft.
  • the blades may extend solely in the upper part of the sleeve and a free granulating space may be situated underneath these blades in the sleeve.
  • the zone of the blades which may rotate at high speed, such as, for example, 1,000 to 3,000 rpm.
  • the rapidly rotating particles of the mixture move in a helical path through the free space underneath the blades in the sleeve towards the lower end of the sleeve. Since the particles of the mixture perform a rolling motion in this free space in the sleeve during their helical downward course along the inner wall of the sleeve, the particles are at the same time built up to form a granulate.
  • the angle of inclination of this spiral is a function of a number of controllable factors of the mixer, such as the speed of rotation of the mixing shaft, the direction of rotation of the blades, the number and the angular positions of the blades, the quantities of powder and of liquid supplied per unit time, and the weight by volume of the mixture obtained.
  • the particles of the mixture will roll along the inner wall of the sleeve for a more prolonged period of time, causing their diameter to increase and their shape to become more regular.
  • the height of the free granulating space underneath the blades is related to and is therefore somewhat limited by the diameter of the sleeve.
  • the central axis of the sleeve may enclose an acute angle with the vertical instead of being vertical itself.
  • an adjusting device may be provided allowing this angle to be adjusted.
  • the sleeve is supported by a pivot plate which comprises a passage opening for said sleeve and which is pivotally supported on one side by stationary brackets so as to pivot about a horizontal swivel axis, while, on the opposite side of the pivot plate, supports which can pivot about an axis parallel to the swivel axis of the pivot plate are fitted in slots in the pivot plate, a screw spindle extending through each support, which screw spindle can pivot about an axis which is parallel to the swivel axis of the pivot plate, each screw spindle bearing a displaceable check nut underneath the support and a displaceable retaining nut above the support.
  • the effect of gravity upon the particles of the mixture may be reduced by properly adjusting the angle of inclination of the sleeve. This feature is of special significance if no high speed of the mixing shaft can be applied in view of the brittleness of the powder supplied into the mixing chamber.
  • Optimum granulating results can be attained by an angular displacement of the blade holders in combination with an inclined position of the sleeve.
  • the mixer may furthermore be provided with an elongated, substantially cylindrical, upright sleeve of flexible material, such as rubber, which forms the wall of the mixing chamber, deforming means being in contact with the outer surface of said sleeve and being displaceable by displacement means with respect to said sleeve in the longitudinal direction of the mixing shaft.
  • an elongated, substantially cylindrical, upright sleeve of flexible material such as rubber
  • FIG. 1 is a schematic vertical section through an embodiment of the mixer according to the invention.
  • FIG. 2 is a top view of a blade holder block with blade holders and blades of the mixer according to FIG. 1.

  • FIG. 4 illustrates schematically a number of blade holder blocks with various designs of blade holders and blades.
  • FIG. 1 illustrates an embodiment of the mixer according to the invention by way of example.
  • This mixer comprises a mixing chamber 1, the wall of which is constituted by an elongated, substantially cylindrical sleeve 2 of flexible material, such as rubber.

  • the liquid component is supplied on a lower level into the upper portion of the mixing chamber 1 through one or more supply pipes 10 which end in spray openings 11.
  • a mounting plate 12 attached to the upper member 8, supports a bearing sleeve 13 for a mixing shaft 14 which protrudes centrally into the sleeve 2 and which is connected at its upper end by an elastic coupling 15 to a drive shaft 16.
  • This drive shaft 16 passes through the mounting plate 12 and through a bushing 17 fixed thereon.
  • the drive shaft 16 is connected to a rope pulley 18 which may be driven by means of ropes (not shown) by a driving means, for example an electromotor. As an alternative, this motor can also be connected directly to the drive shaft 16.
  • the bearing sleeve 13 accommodates bearings 19, 20 for the mixing shaft 14.
  • the mixing shaft 14 carries a number two, in the embodiment shown of downwardly spaced blade holder blocks 21, each of which is equipped with four blade holders 22 into which blades 23 are fitted.
  • the bottom plate 6 is mounted on a pivot plate 24, likewise provided with a passage opening for the sleeve 2 which is in line with the passage opening in the bottom plate 6.
  • the pivot plate 24 is supported on one side in a pivotal manner by stationary brackets 25 and may pivot about a horizontal swivel axis.
  • supports 26, which may pivot about an axis which is parallel to the swivel axis of the pivot plate 24, are fitted in slots 27 in the pivot plate 24, which slots 27 are perpendicular to this swivel axis.
  • a screw spindle 28 extends through each support 26 and may pivot at 29 about an axis which is parallel to the swivel axis of the pivot plate 24.

  • the pivot plate 24 may be pivoted with the aid of the check nut 30 and the retaining nut 31, allowing the angle which the central axis of the sleeve 2 makes with the vertical to be set between, for example, 0 and
  • the blade holder blocks 21 with the blade holders 22 and the blades 23 fitted therein extend solely in the upper zone of the sleeve 2, a free granulating space 32 being thus provided underneath these blades 23 in the sleeve 2.
  • the rapidly rotating particles of the mixture move in the free space 32 underneath the blades 23 in such a way as to follow a helical course towards the lower zone of the sleeve 2, the particles performing a rolling motion along the wall of the sleeve 2 and being built up to form a granulate.
  • the granulated particles which leave the sleeve 2 at the underside are still moist and, in many cases still possess insufficient strength. Therefore, these particles may be conveyed to a dryer (not shown).
  • the blade holder blocks 21 mounted on the mixing shaft 14 have an at least substantially square outer circumference.
  • this outer circumference may also have the form of an equilateral triangle or of another equilateral polygon.
  • a blade holder 22 is fixed to each side of each blade holder block 21.
  • Each blade holder 22 has two slots 33, wherein the end portion of a blade 23 is detachably locked with the aid of a bolt 34 having a smooth end which fittingly projects through a hole in the end portion of the blade.
  • Each blade holder 22 is secured by means of two bolts 35 to a retaining member 37 which is rotatable through 360 about an axis of rotation perpendicular to the mixing shaft 14.
  • This retaining member 37 is accommodated in a chamber in the corresponding blade holder block 21 and is secured against outward displacement by means of a collar 36 of the blade holder block 21.
  • the retaining member 37 may be locked in each angular position with respect to the corresponding blade holder block 21 with the aid of the bolts 35.
  • Each retaining member 37 fits with a central centering ring 39, which projects from the end face 38, in a recess 40 in the corresponding blade holder 22.
  • Each side of each blade holder block 21 is provided with a cylindrical recess 41, the central axis of which is perpendicular to the mixing shaft 14 and into which a cylindrical end of the corresponding blade holder 22 is fittingly inserted.
  • filling rings 42 are arranged between the bottom of the cylindrical recess 41 in the blade holder block 21 and a projecting outer annular flange 43 of the corresponding blade holder 22.
  • the filling rings 42 can be used, for example, when the blades 23 have become shorter under the influence of wear and the amount of play between their end and the sleeve 2 has become too large, which has a harmful effect upon the mixing quality.
  • Each blade holder block 21 has a cylindrical bore through which the mixing shaft 14 extends. Each blade holder block 21 is displaceable along the mixing shaft 14 and can be fixed in each position with respect to this mixing shaft 14 by means of bolts 44.
  • FIGS. 4a-d At most two blades 23 can be fastened in each blade holder 22. Several blade positions are shown in FIGS. 4a-d.
  • the blade holders 22 bear, in the position shown, one blade 23 pointing obliquely upwards and one blade 23 pointing obliquely downwards.

  • the blade holders 22 bear two horizontal blades 23, and in FIG. 4d the blade holders 22 are equipped with only one blade 23 in horizontal position.
  • the other slot 33 of the blade holders 22 receives a filling piece 45 which is detachably locked with a bolt 34 in the same manner as a blade 23.
  • a blade holder block 21 It is possible to equip a blade holder block 21 with two blade holders according to FIG. 4a or FIG. 4b, and with two blade holders according to FIG. 40 or FIG. 4d. Use can also be made of other combinations of different sets of blades 23 for each blade holder block 21.
  • the downwardly moving material is brought into turbulence by the rotating blades 23.
  • the measure of this turbulence can be influenced by such factors as the choice of the blades 23, their shape and their angular position.
  • the obliquely positioned blades 23 convey the product to the centre of the mixing chamber 1, while the horizontal blades 23 mainly have a centrifugal effect and convey the material to the wall of the sleeve 2.
  • the material thus assumes the aforementioned helical course along the wall of the mixing chamber 1.
  • the pitch of the spiral can be adjusted in several ways, 21.0. by rotating the blade holders 22 with respect to the corresponding blade holder blocks 21.
  • the mixing chamber 1 will generally be filled only partially with the initial material and the mixture obtained therefrom, the balance being made up by turbulent air which contributes toward cooling the product.
  • the particles can float freely in the turbulent air, in which way it is reached that the liquid particles are not rubbed into the powder particles but are enveloped by the powder particles. A mixture is thus obtained which consists of externally dry particles.

  • This support 46 bears a plurality of rollers 49, each of which has an axis of rotation which crosses the mixing shaft 14 perpendicularly.
  • the support rings 48 which are coaxial with the sleeve 2, are each equipped with two roller groups comprising a plurality of rollers 49 that are uniformly distributed over the circumference of the wall of the sleeve 2.
  • the rollers 49 in successive roller groups are arranged in staggered and overlapping positions with respect to each other.
  • Each roller 49 is journalled on a bearing strip 50 which is secured to the corresponding support ring 48.
  • the support 46 comprises guide bushings 51 which are fastened to upright strips 47 and which are slidably mounted on guide rods 52 that are parallel to the mixing shaft 14. These guide rods 52 are rigidly secured between the top plate 5 and the bottom plate 6.
  • the support 46 is provided with lateral strips 53 which are engaged by the piston rods of a number of cylinder and piston assemblies 54 which are mounted on the bottom plate 6 and which can impart a reciprocating movement to the support 46 and therefore to the rollers 49.
  • rollers 49 the circumference of which may be adapted to the shape of the wall of the sleeve 2 and which are in contact with the sleeve 2, bring about a local inward bend in the flexible sleeve 2 during their reciprocating movement.
  • the cylinder and piston assemblies 54 are so controlled that they impart a continuous reciprocating movement to the support 46 and to the attached roller groups.
  • Each roller 49 induces at its location of contact with the sleeve 2 an inward bend in the sleeve 2. Since the flexible material, specifically rubber, of which the sleeve 2 is made, although deformable is virtually not compressible, the sleeve 2 will slightly protrude immediately above and below the inward bend that has been formed.
  • Protruding ridges are further formed in the flexible sleeve 2 between the rollers 49 of the groups. Since the rollers 49 in successive groups are mutually staggered in the manner described, the protruding ridges and the inward bends of the flexible sleeve 2 are always staggered in the same way with respect to each other.
