Definitions

  • the invention relates to a mixing machine for mixing a powdery dry substance, in particular dry mortar or dry color powder, with water, in particular with a funnel-shaped storage container for the powdery dry substance, and with a conveying and mixing device for discharging the powdery dry substance from the storage container with addition and mixing with water.
  • the particular field of application of the invention is a mixing machine for producing mortar and a mixing machine for producing paint.
  • a mixing machine for producing paint
  • water is added to the dry mortar and mixed with it, so that the required wet mortar is produced.
  • the paint mixing machine starts with dry paint powder, which is mixed with water to produce the wet paint.
  • the known mortar mixer has a funnel-shaped storage container for receiving the dry mortar.
  • a separate, tubular conveying and mixing device for discharging the dry mortar from the storage container while adding and mixing with water can be flanged to the lower discharge opening of the storage container.
  • a disadvantage of this known mortar mixing machine is that the conveying and mixing device must be attached to the silo container as a separate part. This means long set-up times, because each time the storage container for the dry mortar is changed, the conveying and mixing device dismantled and then flanged to the new reservoir.
  • the funnel-shaped silo outlet prevents evenly flowing bulk goods from slipping.
  • the object of the invention is to create a mixing machine of the type specified at the outset, which is easier to use.
  • the invention proposes that the conveying device is arranged inside the storage container in the bottom area and integrated in this, and that the mixing device is arranged outside of the storage container, the storage container having a corresponding, in particular lateral opening in which the Conveyor opens and from which the mixing device starts.
  • the mortar mixing machine is suitable for all factory-mixed ready-mixed mortars, for example for lime-cement plasters, cement plasters, scratching plasters, fine plasters, structural plasters, fillers, adhesive mortars, reinforcing mortars.
  • the advantage lies in the fact that the ready-mixed mortar can be fed directly to the mixing machine without the paper sacks previously used and having to be disposed of.
  • the wet mortar can be applied to any mortar container or pump.
  • the machine consists of one unit, which allows quick, convenient transportation with small, handy dimensions and low weight.
  • the basic idea is to integrate all the necessary parts in order to convert the stored dry mortar into the state of use as wet mortar.
  • the special design of the storage container with the conveying device ensures that the dry material continues to slide.
  • the water is admixed in a technically simple manner during the discharge of the dry mortar from the storage container.
  • the conveying device in particular in the form of a conveying helix, is led to the outside through a corresponding connection or discharge nozzle, the mixing helix of the mixing device forming the continuation of the conveying helix of the conveying device.
  • the conveyor device has a conveyor shaft with a screw conveyor. This represents a technically simple possibility for discharging the dry mortar stored in the storage container from the storage container and feeding it to the mixing device.
  • the conveying device preferably opens into a metering tube arranged in the region of the opening of the storage container.
  • the dry substance is thus fed through the screw conveyor located in the storage container to a metering screw which conveys a constant amount of dry substance into the flanged mixing device.
  • the mixing device has a mixer tube with a mixer shaft arranged therein and with a water supply.
  • the required amount of water is fed to the mixing tube through an installed water metering system.
  • the mixing shaft located therein then works up the mixture into the wet substance, for example wet mortar.
  • the water supply is preferably controlled by means of a solenoid valve which is coupled to the control of the drive motor. This integrated control of the water metering represents a further possibility for the fully automatic operation of the mixing machine, so that operating personnel can be saved accordingly.
  • the mixing device can preferably be fastened as a separate component to the opening of the storage container. For this it is only necessary to provide the mixing device and the storage container with a corresponding coupling device. This applies equally to the conveyor spiral and to the mixing shaft, which must be able to be coupled accordingly so that the conveyor spiral drives the mixing shaft. For example, locking clamps can be used to fasten the mixing device to the storage container. At the end of the work, only the mixing tube has to be removed from the storage container and rinsed with water. The dry matter in the container can remain or be discharged through an appropriate emptying opening.
  • the mixing device for the non-use state of the machine can be arranged below the hopper slope of the storage container in such a way that it does not protrude beyond the basic cross-sectional area limitation of the machine.
  • the type of arrangement and the length of the mixing device should be selected such that the mixing device does not protrude beyond the basic cross section of the machine and thus with regard to the pallet capacity of the Mixer doesn't bother. This creates a very compact machine that is also very easy to use.
  • a preferred development of the mixing machine according to the invention proposes that an additional, separate conveying and mixing device can be arranged essentially vertically at the mouth of the essentially horizontally arranged mixing device.
  • This development has the advantage that, if necessary, the additional conveying and mixing device can be attached to the basic mixing device, so that the wet substance produced is exposed to the mixing tools for a longer and more intensive exposure. The mixing intensity can thus be increased in the downward area.
  • there is a better supply of the prepared mixture to the pump because the supply to this pump is then supported in the downward region by gravity.
  • the additional conveying and mixing device runs essentially vertically, it increases the basic cross section of the mixing machine only insignificantly, so that it hardly disturbs.
  • the additional, separate conveying and mixing device can preferably be suspended. This has the advantage that the additional conveying and mixing device can be attached to the basic mixing device and then dismantled again without major technical measures.
  • the mouth of the mixing device is on the underside. This has the advantage that the basic mixing device can also be operated without the additional conveying and mixing device. If the separate conveying and mixing device is then suspended in the basic mixing device, a corresponding feed connector comes to lie below the mouth of the basic mixing device, which feeds the wet substance to the actual conveying and mixing pipe.
  • a further development of the mixing machine according to the invention proposes that for the production of paint, whereby dry paint powder is mixed with water, the mixing device has a dough zone with a mixing and conveying device for the supplied dry paint powder and with a water supply arranged on the mixing and conveying device, furthermore has a grinding zone downstream of the dough zone for grinding the color powder mixed with the water and finally has an outlet downstream of the grinding zone for the finished color.
  • the mixing device has a dough zone with a mixing and conveying device for the supplied dry paint powder and with a water supply arranged on the mixing and conveying device, furthermore has a grinding zone downstream of the dough zone for grinding the color powder mixed with the water and finally has an outlet downstream of the grinding zone for the finished color.
  • the known production process has the disadvantage that it is not possible to produce the liquid paint continuously, since so far the paint can only be mixed in portions.
  • the development of the mixing machine according to the invention creates an automatically operating color mixer, by means of which a continuous production of color is possible, so that the supplied dry color powder can be applied continuously and without interruption, for example on a facade, after mixing with water.
  • the basic idea of the manufacturing device according to the invention is that the dry color powder to be processed is first fed to the manufacturing device by means of an appropriate device.
  • the dry color powder is first mixed with water in the dough zone, so that a type of dough or porridge is formed, which is simultaneously fed to the downstream grinding zone during the mixing process, where the dough or porridge is then ground and thus homogenized in order to in this way to obtain the finished liquid color with the usual conventional consistency.
  • This finished paint can then be discharged through the outlet, for example by pumping off the liquid paint and processing it immediately.
  • this is a multi-stage system in which a dough or porridge is first produced, which is then made more uniform by a grinding process.
  • the dough zone preferably has a mixing and conveying tube with a shaft arranged therein and with the water supply.
  • the shaft is thus rotatably mounted within the mixing and conveying tube and has corresponding mixing paddles or comparable devices for the mixing process and transport paddles for conveying the dough or slurry, for example in the form of inclined blades.
  • this transport paddle it is of course also conceivable to use other transport devices, for example a screw conveyor.
  • a further development of the manufacturing device according to the invention proposes that the water supply quantity can be controlled as a function of the color powder delivery quantity. This means that a well-dosed and fixed amount of water is always added to the conveyed paint powder, so that the paint automatically receives the desired water content.
  • this consists of a A large number of bodies which are moved toward one another and lie in a tight packing against one another, through which the pasted paint can be passed.
  • the basic idea of the grinding device designed in this way is to provide a large number of loose bodies, which are moved against one another in particular by moving a corresponding receptacle.
  • the bodies sliding against one another and rolling on one another thus define small grinding and mixing units between them, with the result that the colored paste or pulp is ground and mixed between the bodies, so that the liquid color is ultimately produced in a homogeneously uniform consistency.
  • the degree of grinding and mixing naturally depends on the length of the grinding zone and the speed at which the paint passes.
  • the bodies are preferably spheres and consist, for example, of glass, metal, ceramic or another suitable solid material.
  • the balls have the advantage that they can roll on each other very well and thus achieve an optimal grinding efficiency.
  • the bodies are arranged in a rotatable, cylindrical drum, the two end walls each being formed by a perforated plate or sieve.
  • the basic idea is therefore to fill such a drum with balls in particular and to set this drum in a rotational movement so that the balls are constantly moved and shifted and thus enable the grinding process.
  • the drum will have a closed cylinder jacket, while the two end faces have openings, one end face serving as an inlet for the pasted paint and the other end face serving as an outlet for the finished liquid paint.
  • the perforated plates or screens for the end walls have corresponding openings, the diameter of which is of course smaller than the diameter of the balls.
  • a preferred constructive design of the drum suggests that it is fixedly arranged on the shaft within the mixing and delivery pipe. This means that when the shaft in the dough zone rotates and the color paste or pulp is formed, the drum in the grinding zone rotates simultaneously and synchronously.
  • the advantage is that the shaft forms a structural unit together with the drum, as does the mixing and conveying pipe, which is not only in the dough zone, but also in the grinding zone, where it is, however, compared to the dough zone for receiving the Drum has a significantly larger diameter.
  • the drum suggests that it be divided into segments, the partitions preferably consist of a perforated plate or sieve.
  • the drum thus has radial partition walls with respect to the central axis, which divide the drum into individual chambers, in each of which there is a ball packing.
  • the partitions can be provided with openings which allow the paint to pass through, but not through the balls.
  • the advantage of the drum segments is that the balls have a certain spatial limitation in their respective segments. Above all, however, the drum segments have the advantage that the paint does not collect in the lower area due to gravity. Due to the segmentation, the drum is evenly filled with paint.
  • the grinding zone can have an additional water supply in order to further dilute the colored dough produced in the dough zone with water.
  • This additional water supply can also be used to continuously clean the inlet face of the drum.
  • this additional water input can also be dispensed with.
  • a further development of the manufacturing device for paint according to the invention proposes that an outlet nozzle of the outlet is rotatably mounted and the required fill level in the mixer can thereby be adjusted.
  • a further development suggests that an additional conveyor for the pasted paint powder is arranged between the dough zone and the grinding zone. This has the advantage that the colored powder pasted in the dough zone is fed to the grinding zone without the formation of dust, so that the pasted color powder is continuously removed.
  • the conveyor preferably consists of fixed and inclined shear blades.
  • a shear zone with at least four shear blades is additionally created between the dough zone and the grinding zone.
  • the pasted paint powder which is rotating, experiences an axial component as a result of the shear blades, which are inclined with respect to the longitudinal axis of the shaft, which ensures that the pasted paint powder is transported forward.
  • the shear blades are preferably evenly distributed around the entire circumference.
  • the already mentioned additional water supply can also be located in the area of these shear blades.
  • This mixing and transport device can be formed by the continuous shaft, which is equipped with corresponding mixing and transport paddles.
  • a further development of the mixing machine according to the invention proposes that the water supply quantity can be controlled as a function of the dry substance delivery quantity. This means that the conveyed dry matter is always supplied with a well-dosed and fixed amount of water, so that by means of this integrated control the wet matter automatically receives the desired water content.
  • a further preferred development of the mixing machine according to the invention proposes that a refill container can be arranged above the storage container, the upper side of the storage container and the underside of the refill container having corresponding openings which can be connected to one another via a connecting line.
  • This is a technically simple way to easily expand the dry matter supply to, for example, more than 2 tons, without the storage container (with its conveying and mixing device) having to be replaced with a new one.
  • the reservoir can be refilled directly at the construction site by placing the full refill container on the reservoir, so that after opening the connecting line, the dry substance of the refill container can flow into the reservoir. After the refill container has been emptied and the storage container has been filled, the empty refill container can be removed again.
  • the refill container is a container with fixed walls.
  • the connecting line is preferably a hose or an accordion-like tube. This represents a technically simple possibility to establish a connection between the refill container and the storage container by flanging the connecting pipe accordingly after opening the corresponding openings. This enables a jam-free transfer from the refill container to the storage container.
  • the refill container can also be a flexible container which can be suspended in a frame which can be fastened above the storage container.
  • a flexible container which can be suspended in a frame which can be fastened above the storage container.
  • Such "big bags" for bulk goods are used as refill units or replenishment units from the production site, for example to a construction site.
  • the advantage of these flexible containers is that they weigh very little, so that they only cause very low return costs for refilling when folded.
  • the useful life of such a flexible container is approximately 5 years.
  • the flexible container is suspended in a holder above the actual mixing machine. If necessary, the outlet hose of the container can then be opened to allow the material to flow into the storage container.

  • a transition piece is preferably placed on the top opening of the storage container.
  • the double outlet hose of the container protrudes into the interior of this transition piece and, on the other hand, it is placed over the transition piece on the outside. Slipping is prevented by means of a so-called bag buckle.

  • This means that the mixing machine can be used on pallets and in high storage. It is accessible on all four sides with a forklift and can be handled with a hand pallet truck.
  • the mixing machine can be transported with all common lifting trucks, forklifts or cranes. Due to the Euro pallet dimensions (80 x 120 cm), the truck loading areas and high-bay storage areas can be optimally used.

The diameter of these balls 66 is of course larger than the diameter of the openings in the end walls 63 and in the partition walls 64. Finally, the mixing and delivery pipe 55 in the area of the grinding zone 53 also has two water feeds 67, which, however, do not necessarily have to be present.
  • the outlet 54 is formed by a flanged outlet nozzle 68 which is rotatably mounted so that the required fill level in the mixer can be adjusted.
  • the outlet 54 is equipped with a hitch for a pump.
  • the shaft 56 is provided with mixing and transport paddles 69 which define an additional mixing and transport device 70.
  • the color mixer works as follows:
  • the shaft 56 with its mixing and conveying paddles 57, 69 and with its drum 62 is rotated so that the paint mixer is in the operating state.
  • Dry paint powder is supplied to the dough zone 51, which is indicated schematically by the arrow P.
  • the dry paint powder is gripped by the mixing and conveying paddles 57 and mixed with the water supplied through the water supply 58 and thereby fed to the shear zone 52.
  • the metered amount of color powder is fed with so much water that a dough is formed which is mixed by the mixing and conveying paddles 57.
  • This slurry enters the shear zone 52 and is conveyed forward by the fixedly arranged and inclined shear blades 60, so that the slurry passes through the end wall 63 in the form of the perforated plate into the segments 65 of the drum 62. Water can be fed in further via the water feeds 67, so that a slurry is formed.
