Definitions

  • the invention relates to a mixer according to the preamble of claim 1.
  • Such mixers are known from DE-PS 2o 57 594. Depending on the pressure of the mix against the throttle valve, it opens more or less. The distance of the counterweight from the pivot axis of the throttle valve can be adjusted so that a basic adaptation to certain predetermined operating conditions, such as the type of chips and the like, is possible.
  • the invention is therefore based on the object of designing a mixer of the generic type in such a way that it is possible to keep the load constant.
  • the embodiment according to claim 5 represents a very particularly preferred embodiment of the invention.
  • the mixer shown in the drawing has a cylindrical mixing container 1, which consists of an inner trough 2 forming the inner wall thereof and a cooling jacket 3 surrounding the inner trough.
  • the mixing container 1 is closed at its ends by end walls 4, 5.
  • end walls 4, 5 At one end of the mixing container 1, which is on the right in FIG.
  • end walls 4, 5 At the other end, which is on the left in FIG. 1, there is also a tangible discharge hopper 8.
  • the mixing container 1 is divided in half in the horizontal plane, the upper half 9 and the lower half 1-o of the mixing container 1 on one long side by hinge joints 11 and on the opposite long side by Toggle locks 12 are releasably and pivotally held together.
  • a mixer shaft 13 is arranged coaxially, which is mounted in bearings 14, 15 and can be driven by a motor 16 by means of V-belts 17 and a V-belt pulley 18 mounted on the mixer shaft 13 in a rotationally fixed manner. Balancing disks 19, 20 are attached to the mixer shaft 13.
  • a cooling water supply pipe 21 is arranged which rotates therewith.
  • threaded bushings 22 are attached, in which hollow mixing tools 23 are screwed.
  • a cooling water pipe 24 branches off from the cooling water supply pipe 21 into each hollow mixing tool 23, so that the cooling water flows through the cooling water supply pipe 21, the further cooling water pipes 24, through the interior of each mixing tool 23 into the annular space located between the cooling water supply pipe 21 and the mixer shaft 13 .
  • the cooling water passes through a cooling water connection 25 - provided on the left in FIG. 1 - into the mixer shaft 13, the cooling water inlet being designated a and the cooling water outlet being designated b.
  • the adjoining region in which the cooled mixing tools 23 are arranged on the mixer shaft 13 is one Post-mixing zone C.
  • Mixing container 1, including bearings 14, 15, is supported against floor 34 by a machine frame 33.
  • Such a mixer is known for example from DE-PS 2o 57 594 (corresponding to US-PS 3 734 471) or DE-OS 27 17 896.
  • glue addition tubes penetrate from the outside the cooling jacket 3 and the inner trough 2, which also end with their outlet openings in the mixing material ring 3o.
  • glue addition tubes penetrate from the outside the cooling jacket 3 and the inner trough 2, which also end with their outlet openings in the mixing material ring 3o.
  • a mixture outlet opening 35 opens into the mixture outlet hopper 8.
  • This outlet opening 35 is in a manner known per se by means of a throttle valve 36 which is adapted to the course of the inner trough 2 in the region of this outlet outlet opening 35 closable, which is articulated on its upper, axially parallel edge by means of swivel joints 37 on the mixing container 1 and swiveled downward and to the side (in FIG. 2 to the right) according to the swivel direction arrow 38 by the pressure of the mixed material from the closed position shown in FIG. 2 can be, so that the material outlet opening 35 is opened more or less, so that in turn the mixing tools 23 moving in the direction of rotation 39 eject the material through the material outlet opening 35, which is then more or less open, into the material outlet funnel 8.
  • a bracket 4o is attached, on the one.
  • the guide rod 41 which extends approximately horizontally outwards, is rigidly fastened.
  • the stator housing 43 of a commercially available spindle motor 44 is displaceably mounted on the guide rod 41 by means of a guide bush 42.
  • the spindle 45 of the spindle motor 44 is articulated with its end facing the mixing container 1 on the bracket 4o with play, the arrangement being such that the guide rod 41 on the one hand and the spinel 45 on the other hand run parallel to one another.
  • a current transformer 52 is connected which outputs a voltage proportional to the current consumption of the motor 16, which voltage is rectified in a bridge rectifier 53.
  • This DC voltage signal is then fed to a controller 54, where it is converted into a corresponding current in a resistor 55.
  • a potentiometer 56 is connected in parallel with the resistor 55 as a setpoint generator, the output of which is connected to the output of the resistor 55. At this interconnection point 57, the current coming from the setpoint generator and the current coming from the resistor 55 are added together.
  • a negative current is specified in each case from the setpoint generator, while a positive current is specified from potentiometer 55.
  • An operational amplifier 58 is connected downstream of the interconnection point 57 and, depending on whether a positive or negative current difference is applied to the operational amplifier from the interconnection point 57, pumps a corresponding signal to a power amplifier 59 connected downstream of the controller 54.
  • the spindle motor 44 is then controlled by the power amplifier 59 and its stator housing 43 is moved on the guide rod 41 until the current consumption of the motor 16 again corresponds to the target value specified on the potentiometer 56.
  • the power amplifier 59 is followed by a solenoid valve 6o, which switches the hydraulic supply either to the liquid line 49 or 5o, the other liquid line then serving as the unpressurized return line. Otherwise, the entire circuit is the same.
  • a counterweight can of course also be provided, which can be displaced on a guide rod by means of a spindle by a motor which is coupled to it, but separately and fixedly attached to the throttle valve 36.
  • the drive is expediently carried out via a countershaft transmission. Since in such a case it would be particularly expedient to provide the motor axially parallel to the swivel joints 37, a bevel drive would also have to be provided in such a case.
