Definitions

  • the invention relates to a device according to the preamble of claim 1 and a method for operating this mixing and conveying device for mortar.
  • Compulsory mixers are superior to the so-called gravity mixers (standard concrete mixers) in that they provide a thorough mixing of the mixes by means of scrapers and motor-driven stirring rods or agitator blades.
  • An advantage of compulsory mixers is that not just combinations of water and a solid Miscible, but also the wet or even dry mixing of several solid components is possible (eg cement, sand and water). Forced mixers work batch by batch - meaning that loading with solid aggregates, adding water, mixing and spreading the mortar are not done simultaneously, but in succession. As a result, there are always interruptions to the work during mixing and pumping.
  • Another disadvantage is the lack of conveying function - in common machines, the material only falls out of the tub bottom or even remains in this.
  • Continuous mixers are suitable for all mortars that are ready for use and that are processed continuously in a continuous process in the same amount in the same consistency.
  • a metering screw for the solid components and a flow meter in a continuous mixing zone continuously in a constant ratio of water and mortar powder are brought together and immediately mixed by means of agitators and ejected from an outlet.
  • the high throughput is particularly advantageous.
  • the disadvantage is the unsatisfactory votingsituation, since no direct pumping is possible here.
  • the object of the invention is to bundle the functionalities of the common mortar processing machines such as pumps, discontinuously operating forced mixers, continuous-flow mixers, cleaning and screed machines in a single machine.
  • a mixing pump according to the invention one has thus basically four machines in a small, universally and flexibly usable. This lowers the investment costs of the target group, increases productivity and flexibility and, through this and its compact design, also appears to be suitable for ergonomic and health benefits in operation.
  • the invention is initially based on a mixing and conveying device for mortar with a mixing and storage container (2) and a drive unit (7) for a stirring device arranged in the mixing and storage container (3), wherein the mixing and storage container has an opening from which mortar material is ausbringbar, characterized characterized in that at the outlet opening a connecting device (17) for additional units is provided such that optionally no, one or more - matched additional units in the form of a pump (11) and a continuous mixing zone (14) is attachable /, so that depending on desired mode of use operation with and without additional unit (s) is possible, the mixing and storage tank is designed for wet operation with wet mortar material and a dry operation with dry mortar material, wherein in wet operation dry aggregates in the mixing and storage tank (2) with liquid Binders such as water can be mixed in batches.
  • Continuous means continuous mixing and, if necessary, pumping out of mortar in a continuous flow process
  • the liquid binders are automatically metered, eg by a flow meter, and added to the flow of material, eg metered by a metering screw conveyor, and mixed in by stirring elements
  • the water as a standard under the hydraulic binders, is automatically taken from a connected water pipe, which benefits from the high processing volumes per unit of time, the continuous flow of material, for example , during the spraying of plasters and the efficient
  • the continuous mixing process only takes place in a continuous mixing zone downstream of the mixing and storage container, so that only dry mortar powder is introduced into the mixing and storage container and always remains dry there This corresponds to the dry operation of the mixing and storage tank. It always gets only as much solid mortar material mixed with eg water, as needed.
  • one or more rotational direction dependent coupling elements e.g. Install freewheels, so that the attached auxiliary units and or the stirring device can be activated or deactivated depending on the direction of rotation.
  • This is particularly important, for example, with regard to the pump module, so that it can be turned off during the discontinuous mixing in the mixing and storage tank by changing the direction of rotation.
  • An eccentric screw pump proposed according to the invention in contrast to e.g. Radial pumps only in one direction of rotation away from the machine. Upon reversal of the direction of rotation of the drive motor, material otherwise contained in a hose, e.g. spray on the plaster, pumped back into the machine, so to speak, which would not make sense.
  • An activation of the stirring device during pumping is also conceivable, e.g. to provide the full engine power to the pumping process and thereby promote further and higher.
  • the pump is favored as an eccentric screw pump, but are also conceivable other constructions such. Piston pumps or other thick matter pumps.
  • the quick connection of the additional units should be e.g. by screwing, tightening, clamping, clamping etc. in or on the connecting device, in particular liquid-tight, done.
  • the Rajaggregate- continuous mixing zone and pump are driven by the drive unit for the stirring device.
  • the engine for the supply of material from the storage container as is usual with common machines, eliminated.
  • the machine is thus small and relatively light, due to the low construction with the engine under the mixing trough, in order to enable larger and more powerful machines but also the use of several motors for the stirrer or the auxiliary units kept open.
  • an electric motor but other drive units such as internal combustion engines come into question.
  • a preferred embodiment of the invention makes use of the common operation of stirring device and auxiliary units of an angle drive to space-saving to connect vertical and horizontal axes.
  • a bevel gear is used.
  • the mixing of large quantities of mortar in the mixing and storage tank requires a lower speed depending on the mixing use than e.g. the relatively high-revving progressive cavity pumps, which is why it is proposed in a further embodiment that a reduction ratio of the shaft for the additional units to the / the shaft (s) for the stirring means of greater than or equal 1: 1 prevails.
  • a screw conveyor For complete transport of the mortar from the mixing & storage tank to the additional aggregates a screw conveyor is provided.
  • the preferred embodiment of the invention is according to the figures 1-4 such that the axis for the stirring means is formed substantially perpendicular. This variant appears to be constructive, since it is particularly small and can do with the fewest parts. It is conceivable according to Figure 5 but also a type in which the driven axles are arranged only horizontally.
  • the cost-effective vertical design also allows a completely modular design, in which the basic unit consists essentially only of a base frame of the body and frame and other relevant parts such as the or the motors, the control electronics, the storage and mixing container, mixing inserts, and possibly Exhaust cover, liquid component flow meter, continuous mixing zone or pump parts can be mounted according to need and size.
  • An additional solenoid valve opens and closes the supply of liquid binder depending on the engine operation of the conveyor shafts.
  • the pump, continuous mixing zone and the outlet are adapted to the particular liquid-tight connection to the connecting device and each other accordingly.
  • the invention relates to a method for operating a mixing and conveying device for mortar, characterized • • characterized in that in the mixing and storage container in discontinuous mixing and conveying dry aggregates are directly processed with liquid binders such as water in batches, during continuous mixing and conveying to the mixing and storage container, however, only dry components are added, which are conveyed to a downstream continuous mixing zone and provided there via an inlet with the respective required amount of liquid binder and mixed with these, wherein the desired functionality with regard to continuous or discontinuous mixing and conveying and the application mode ejection or pumping is achieved by the selection of the cultivation modules or mixing inserts used.

  • mortar powder such as cement with water and possibly also with other additives such as sand is entered in the appropriate proportions and mixed by the (in the drawing stylized) mixing blades (28) of the interchangeable mixing insert (3) .
  • the speed of the motor (7) is reduced via the gear (25) and transmitted via the bevel gear (23, 24) to the mixing shaft receptacle (5).
  • the discontinuous mixing in the mixing and storage container (2) takes place in the opposite direction of application of the material, since in this the freewheel (22) releases as a direction of rotation dependent coupling element the connection from the engine to the attached additional units and thus prevents a possibly attached eccentric screw pump thereof to pump backwards.
