Definitions

  • Transport mixers of the type mentioned include by the
  • the transport mixer described there has a cylindrical transport container, the longitudinal axis of which is arranged horizontally on the frame of a vehicle.
  • a drive motor is assigned to the transport container and can rotate the cylindrical transport container - guided by corresponding bearings on the frame - about its axis.
  • the transport container has a lockable on its cylinder wall approximately in the middle of its length
  • a mixing spiral is arranged on the cylindrical inner wall of the transport container, through which the viscous concrete in the transport container is axially conveyed and mixed in the process.
  • At the rear end of the transport container there is an opening on the face near the circumference of the transport container through which the mixture is passed into an annular discharge channel.
  • This discharge channel extends approximately over an angle of 240 °.
  • a second channel is assigned to it on the inside.
  • a spiral wall is arranged downstream of both channels, which leads the mixture which flows out of these channels as it rotates further back to the central discharge opening. This discharge opening is open to the rear of the transport container.
  • the object of the invention is to provide a transport mixer with a horizontal, cylindrical transport container,
  • the conveyor spiral does not have to be involved in the distribution process.
  • the height of the mixing spiral which has been reduced to a minimum, enables the mixture to be maintained even at a very high level with little energy consumption.
  • the design of the discharge channel ensures that large quantities of the mixture can be applied almost continuously in a very short time.
  • the discharge channel is simple in its design, allows an undisturbed flow of mixture on the one hand and on the other hand of the cleaning water into the space of the transport container.
  • the proposed combination enables large quantities of bulk material mixtures to be transported with short loading and unloading times.
  • a capacity of up to 15 can be achieved with such designs.
  • the limit of the capacity of the inclined, pear-shaped transport containers is 12m 3 .
  • the design of the opening mechanism according to claim 3 ensures the use of simple, proven and robust control elements which guarantee high functionality.
  • the control of the opening mechanism in three positions - according to claim 4 - enables repeated opening and snapping of the flap and helps to remove residues of the mixture from the seal of the flap.
  • the stationary funnel above the inlet opening and the arrangement of its support arms according to claim 5 ensure a low-loss introduction of the bulk material.
  • the support arms secure the transport container on the frame of the vehicle.
  • the design of the conveying spiral enables the mixture to be maintained during transport. However, it also ensures low-residual transport of the mixture to the discharge side and cleaning when the water level is low.
  • Claim 7 defines the optimal results obtained during testing.
  • the features of claim 8 bring advantages in maintaining the mixture without the energy required to rotate the transport container must be increased.
  • the placement of the discharge channel on the outside of the front side of the transport container enables the channel to be accessible from all sides for tapping off any remaining hardness in the interior of the channel.
  • the execution of the discharge channel according to claim 10 ensures consistently good sliding possibilities for the mixture.
  • Claim 11 optimizes the cleaning of the transport container.
  • the claim 12 uses the stabilizing effect of the end wall of the transport container for supporting the race.
  • the combination with a powerful vane cell thick matter pump is possible.
  • the mixture can be conveyed in a very short time and over great distances, even at heights of 30-40 m, with a low power requirement.
  • the transport mixer 2, 3 is mounted in the usual way on the frame 2 of a vehicle 1.
  • the cylindrical transport container 3 is rotatably mounted on this frame 2.
  • the axis of the transport container 3 is oriented essentially horizontally.
  • the drive motor 21 can be controlled in such a way that the transport container 3 can perform drive functions as a function of its respective angle of rotation.
  • the speed of this drive 21 should be freely adjustable within normal limits.
  • the transport container 3 is usually mounted on a pin on its drive side (not shown).
  • a conveyor spiral 311 is attached to the cylinder wall 31 of the transport container 3, the wing height H1 ... H5 of which increases continuously or step-wise from the end wall 32 on the drive side to the end wall 33 on the discharge side.
  • the leaf height H1 ... H5 is at least about 2% of the diameter of the transport container 3 and then rises to about 20% up to the end wall on the discharge side.
  • 3 mixing profiles 312 are arranged on the inner circumference of the transport container.
  • a filling opening 313 is provided on the cylinder wall 31 for filling the mixture of bulk material and liquid.
  • This filling opening 313 is located on the top of the transport container 3 during the filling process. It is arranged approximately in the middle so that the mixture 4 introduced is itself distributed evenly in the interior of the transport container. This avoids the need to use the conveyor spiral 311 during the filling process by rotating the transport container 3.
  • the swivel arm 3151 also carries a roller 3153 which can be influenced by a controllable stop 262.
  • the flap 315 is held in the closed position by a spring 316.
  • An opening mechanism 26 is arranged on the funnel 25.
  • This opening mechanism 26 has an adjusting piston 261 and a pivotable stop 262, which can assume three different positions with respect to the orbit of the roller 3153.
  • the third position of the stop 262 ensures that the filling opening 313 is completely opened.
  • the flap 315 then assumes the vertical position shown in FIG. 5.
  • the transport container 3 can be sealed sufficiently tightly.
  • the mass of the mixture 4 in the transport container 3 additionally supports the sealing.
  • the transport container 3 is closed by the end wall 33.
  • the end wall 33 In the end wall 33 there is a discharge opening 331 through which the mixture 4 can flow into the discharge channel 332.
  • the discharge channel 332 is arranged in the peripheral region of the transport container and is placed on the end wall 33 on the outside. This discharge channel 332 extends over an angle that is greater than 220 °, concentrically to the transport container 3.
  • this discharge channel 332 At the end of this discharge channel 332 facing away from the discharge opening 331, it merges tangentially and in an arc into the guide channel 333, which guides the mixture 4 into the plane of the axis of rotation of the transport container 3.
  • This guide channel 333 has an opening 3331 on the inside, which opens into the wall of the discharge funnel 334.
  • the mixture 4 conveyed by the conveying spiral 311 with the corresponding direction of rotation B into the region of the discharge opening 331 is first in this direction of rotation into the discharge channel 332 and via the guide channel 333 and the funnel 334 to the outside.
  • the concrete can be led to where it is to be processed by means of a slide or other suitable aids.
  • FIG. 2 shows the mode of operation in the direction of rotation A, which serves to mix the mixture 4 in the transport container 3.
  • the conveyor spiral 331 conveys the mixture 4 in the direction of the end wall 32 on the drive side.
  • the filling process takes place in the position at 0 ° (FIG. 2).
  • the discharge opening 331 is located in the upper region of the transport container 3. Upon further rotation in the direction A (90 °), this opening 331 is immersed in the mixture 4. The liquid mixture 4 can thereby collect in the discharge channel.
  • Viscous mixtures 4 will only penetrate slowly into the discharge channel during this process. If the discharge opening 331 lifts out of the mixture 4 (180 ° to approximately 300 °), the discharge channel 332 is empty again. An overflow of the transport container 3 via the discharge channel 332 is practically impossible.
  • the discharge process is shown in FIG. 3 in four different angular positions.
  • the discharge channel is initially empty (0 °).
  • the discharge channel 332 fills (180 °).
  • the mixture 4 in the discharge channel reaches the same filling level 41 as the mixture 4 in the transport container.
  • This discharge of the mixture takes place at a high fill level 41 over an angular range which is significantly greater than 180 °.
  • the discharge channel 332 has already taken up mixture 4 again via its opening 331 and, after only a short pause, feeds it to the discharge funnel 334.
  • the mixture can be discharged continuously and the discharge speed can be regulated as desired by regulating the drive speed.
  • the bulk material is first mixed dry and shortly before the loading process with water.
  • the finished mixture 4 is introduced at high speed through the opened filling opening into the stationary transport container 3. It distributes itself instantly without the need for further aids for the distribution in the transport container.
  • the flap 315 is finally closed after being slammed shut several times.
  • the seal 3131 is freed of mixture residues.
  • the flap 315 closes tightly.
  • the transport container 3 is now turned in the direction A. The transport can begin.
  • the mixture can be maintained during transport by the low wing height H1 ... H5 and by the mixing profiles 312 with low energy consumption at low speed A.
  • the discharge speed can be determined by regulating the discharge speed B.
  • a corresponding, necessary drive movement can be either from the engine of the vehicle or from another
  • the suction channel of the pump may be different
  • the hose 62 can be attached to the transport vehicle 1 and carried along. At the construction site, he is manipulated with the crane there. List of the reference symbols used
