Definitions

  • the invention relates to a transport mixer for bulk liquid / liquid mixtures, consisting of a cylindrical transport container mounted on a frame with an approximately horizontal axis and a reversible, controllable drive for the transport container depending on the angle of rotation, the transport container being provided with a closable filling opening on its circumference is on the inside of its cylinder wall has a conveyor spiral and in the area of its rear end wall has an annular discharge channel with an inward discharge opening.
  • Transport mixers of the type mentioned have become known, inter alia, from US Pat. No. 2,038,158.
  • 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 closable fill opening on its cylinder wall approximately in the middle of its length, which can be opened when it is located on the top of the transport container.
  • 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.
  • the filling opening arranged in the middle of the transport container ensures that the mixture flows in and is distributed quickly in the transport container.
  • the conveyor spiral does not have to be involved in the distribution process.
  • the position and arrangement of the flap ensures that the transport container is sealed tightly during transport.
  • 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 the transport of large quantities of bulk material mixtures with short loading and unloading times.
  • a capacity of up to 15 m 3 can be achieved with such designs.
  • the capacity of the inclined, pear-shaped transport containers is limited to 12m 3 .
  • the design of the opening mechanism according to claim 3 ensures the use of simple, proven and robust controls that 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 conveyor spiral enables the mixture to be maintained during transport. But it also ensures the low-residual transport of the mixture to the discharge side and cleaning when the water level is low.
  • Claim 7 defines the optimal results determined during the test.
  • 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 thick matter pump is possible.
  • the mixture can be pumped at low power requirements in a very short time over long distances - even at heights of 30 - 40 m.
  • 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 aligned 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). In the area of the discharge elements there is an additional support bearing 23 which interacts with a race 34 on the circumference of the transport container 3.
  • a conveyor spiral 311 is attached, 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 introduced mixture 4 itself is evenly distributed 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.
  • a flap 315 is assigned to the filling opening for the purpose of tight sealing.
  • This flap 315 has a swivel arm 3151, which around a bearing 3152, which is attached to the outer wall of the transport container 3, can swing.
  • 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 actuating piston 261 and a pivotable stop 262, which can assume three different positions with respect to the orbit of the roller 3153. In a first position, the stop 262 never reaches the area of the roller 3153. The flap remains closed. In a second position, the so-called Snap position, the role 3153 is only shifted by no amount. The flap 315 is opened only briefly in order to immediately return to the closed position under the action of the spring 316. This method of operation is necessary in order to remove mixture residues from the seal 3131 on the frame 314 of the filling opening 313 before the flap 315 is finally closed by impact.
  • 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. In this position, mixture residues slide off the flap 315 without resistance.
  • 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 At the rear end of the transport container 3, at the so-called. Discharge side, the transport container 3 is closed by 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 outside of the end wall 33. 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 a corresponding direction of rotation B into the region of the discharge opening 331 will first reach the discharge channel 332 and via the guide channel 333 and the funnel 334 in this direction of rotation.
  • the concrete can be taken to where it is to be processed.
  • the mode of operation of the discharge device is again shown in FIGS. 2 and 3 in different positions - with reference to a direction of rotation of the transport container.
  • FIG. 2 shows the mode of operation in the direction of rotation A, which is used 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 direction A (90 °), this opening 331 dips into 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 that is significantly greater than 180 °. If this discharge has ended with the first rotation, 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 into the stationary transport container 3 at high speed through the opened filling opening. It distributes itself instantly without the need for further aids for the distribution in the transport container.
  • the flap 315 is finally closed after repeated slamming (overlapping). The seal 3131 is freed of mixture residues. The flap 315 closes tightly.
  • the transport container 3 is now rotated in 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 direction of rotation of the transport container 3 is changed to direction B for the purpose of emptying.
  • the discharge speed can be determined by regulating the discharge speed B.
  • vane pumps which can be used to pump thick matter - such as lightweight concrete or screed - quickly and reliably over long distances, even at great heights.
  • such a pump 6 - which has a relatively small mass - is directly attached to the transport mixer 3.
  • a corresponding, necessary drive movement can be derived from the engine of the vehicle or from another engine.
  • a collecting container 61 for the discharged mixture on the suction channel of the pump may compensate for different delivery rates and serves as a known buffer.
  • 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.
