Definitions
- the invention relates to a ring trough positive mixer, consisting from a trough with a central dome-shaped part, in which in the middle the mixer shaft driven by an agitator motor is mounted from a with the upper end of the mixer shaft non-rotatably connected hub-shaped part, on which several mixing blade ends Arms are arranged that the between the outer support wall and the dome-shaped part of the ring channel pass through, and from a connectable to the hub-shaped part radial arm, one at its outer end Vortex carries the one that runs parallel to the agitator shaft Vortex shaft is provided with a rotary drive.
- a ring trough positive mixer known from practice this
- the rotary drive of the vortex shaft consists of a hydraulic motor, via a separate hydraulic pump with servo adjustment is driven and, depending on the mixing recipe, continuously between 0 is controllable up to 200 rpm.
- This hydraulic drive the Vortex shaft is not only due to the required hydraulic motor associated hydraulic pump is expensive, but it is additional still more expensive due to the required rotary union. task the invention is therefore a ring trough positive mixer to create the type specified at the beginning with a cheaper Drive for the swirler is provided.
- this object is achieved with a ring trough positive mixer of the generic type solved in that with the hub-shaped Part of a flat one enclosing a radial arm Housing is connectable, in the middle part of a central, with the agitator shaft aligned shaft is mounted on the rotatable a central gear is keyed up and its top out the shaft end led out through a torque arm is supported against the trough, and that in the arm-shaped Part of the housing at least one pinion is mounted, that transfers the drive from the central gear to the swirler and with a gear wheel wedged onto the vortex shaft combs.
- the drive according to the invention is characterized by large Robustness and economy because it has no additional Drive motor needed, but via the gear means of that Agitator drive is derived. Even those already in operation Ring trough compulsory mixers without swirlers can be used in simple Be retrofitted with the swirler according to the invention.
- a ring trough positive mixer is known, at which is the drive of the whirlers via spur gear stages from the mixer drive is derived.
- This well-known ring trough mixer however, has a complex construction than in the interior of the ring trough with a gearbox provided gear and inserted in the space between the gear housing and the inner wall of the trough with an internal toothing provided ring gear is arranged trough-proof, with the To derive the vortex drive, a gear meshes a shaft bearing a pinion of the spur gear set which is the bottom plate of the rotor housing of the ring trough positive mixer enforced.
- the flat housing can have two swivel-bearing arms.
- a gear chain consisting of spur gears which is one sprocket more than the other's gear chain Arms has, so that the vortexes rotate in opposite directions can and thereby an even better mixing effect is achieved.
- a sprocket is provided that over the vortex shaft drives a sprocket on this by a chain.
- the hub-shaped part expediently has an upper part flat annular edge, with the end face the lower wall the middle part of the flat housing can be screwed.
- the vortex shaft can be in a bearing tube connected to the arm be stored, which enables good encapsulation.
- Vortexes are attached to a ring on the end of the vortex shaft freely rotatable and opposite to the vortex shaft is held against rotation by shear pins. Should the swirler due to stones or other resistances in the mix blocked, damage to the ring trough compulsory mixer thereby avoided that the shear pins are sheared off and the vortex despite the continued rotation of the vortex shaft stop.
- the torque arm expediently consists of a rotationally fixed radial connected to the shaft of the central gear Lever, the outer end of which is supported by springs against the trough is. This is preferably provided in both directions of rotation Resilient support allows strikes to occur resiliently flexible to absorb and dampen.
- the ring trough mixer (1) shown in FIG. 1 consists from a trough (2) with in the illustrated embodiment cylindrical outer wall (3) and a flat circular disk-shaped Floor (4), which is supported on the floor via support feet (5) is.
- the trough (2) has a dome-shaped interior Part with a cylindrical peripheral wall (6), the lower edge connected to the circular disc-shaped bottom (4) is.
- the dome-shaped part is covered by an upper cover wall (7) closed that with a medium circular breakthrough is provided, through which the mixer shaft (8) passes which is sealed against the top wall (7) by a seal (9) is sealed and with the output shaft of a geared motor (10) is coupled, the brackets (11) rotatably with the cylindrical wall (6) of the cathedral is connected.
- a hub-shaped part (12) is wedged, the is sealed against the cylindrical wall part (6) and angled arms (13) distributed over its circumference mixing blades stroking the ends of them over the bottom of the ring trough (14) are arranged .
- a shaft (18) is, which led out of the housing upwards and is sealed against this.
- the shaft (18) carries on lower end of a central gear (20) which is on a common Diameter line on both sides of these Pinions (21 and 22, 23) combs the gears (24, 25) of the Drive the vortex shafts (26, 27).
- a central gear (20) which is on a common Diameter line on both sides of these Pinions (21 and 22, 23) combs the gears (24, 25) of the Drive the vortex shafts (26, 27).
- the Shaft (18) rotatably with a radial lever (29) existing radial torque arm connected, its free End over compression springs (30) on trough-resistant abutments (31) is supported.
- the upper end of the shaft (18) can be used instead of the torque arm (29) with the output shaft one in its speed controllable and reversible gear motor (33) be coupled, also by a carrier, not shown is kept trough-proof.
- FIG. 3 shows another embodiment of the ring trough compulsory mixer basically corresponds the embodiment of FIG. 1, so that the same for the same parts Reference numbers are used.
- the vortex shafts (26, 27) are in bearing tubes (37) through roller bearings stored. There are disks on the ends of the vortex shafts (26) (38,39) non-rotatably, with a circumferential one between them limit annular groove in which an annular disc (40) is freely rotatable with an outer flange (41) is provided with one that carries the swirl elements (42) Ring (43) is screwed.
- the freely rotatable in the ring groove mounted disc (40) is by shear pins (44) with the lower ring (39) connected to the swirl shaft, connected in a rotationally fixed manner, so that the vortex elements (42) rotate with the vortex shaft, as long as the cross pins (44) as a result of the swirl elements blocking resistors have not been sheared off.
