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.
  • a mixing machine in the form of a mortar mixing machine of the type specified at the beginning using a small silo of, for example, 1.2 tons or larger is used to produce the required wet mortar at the respective place of use.
  • 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 mixing machine is that, in the case of an empty storage container, it is only possible to continue working if it is exchanged for a full storage container. But this means an interruption of work.
  • the object of the invention is to create a mixing machine of the type specified at the beginning, with which continuous work is possible without interrupting work.
  • the invention proposes that a refill container can be arranged above the reservoir, the top of the reservoir and the underside of the refill having corresponding openings which can be connected to one another via a connecting line.
  • the storage container can be refilled directly at the construction site by placing the full refilling container on the storage container, so that after opening the connecting line, the dry substance of the refilling container can flow into the storage container. After the refill container has been emptied and the storage container has been filled, the empty refill container can be removed again. This makes it possible to work continuously without interrupting work.
  • the refill container is a container with fixed walls.
  • the refill container can preferably be placed on the frame. This is a simple way to arrange the refill container on the storage container.
  • the refill container has a corresponding cross-sectional shape suitable for pallets, such as the frame. This results in easy transportation options.
  • 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 connecting line is fixedly arranged at the opening of the refill container and can be pulled downward for flanging on the opening of the storage container.
  • the connecting line is permanently arranged on the refill container and only needs to be pulled down to fill 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.
  • 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.
  • the refill container preferably has an outlet hose for attachment to the opening of the storage container.
  • An additional connecting device can thus be dispensed with.
  • outlet hose of the refill container is double and protrudes on the one hand into the interior of a transition piece and on the other hand is put over the transition piece on the outside.
  • 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.
  • the frame can preferably be adapted to the length of the container by means of extendable feet.
  • the machine has a frame with a uniformly rectangular cross section over its entire height.
  • This means that the mixing machine can be used on pallets and in high storage. She is with a forklift accessible on all four sides 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. Extendable feet of the frame must be pushed in for transport on a truck or a trailer. This eliminates the need for an additional transport lock due to the low center of gravity.
  • FIGS. 7 and 8 show the basic version of a mortar mixing machine, while in FIGS. 7 and 8 the extension form according to the invention with a refill container is shown in two embodiments.
  • the basic version of the mortar mixing machine shown in FIGS. 1 to 6 has a rectangular frame 1 in Euro-pallet size (80 x 120 cm) and is stackable.
  • This Frame 1 has feet 2 which can be pulled out to different heights and which are shown in broken lines. This means that any standard mortar pump and other vessels of different heights can be loaded.
  • Inside the frame there is a funnel-shaped storage container 3, which tapers conically downwards, as can be seen in particular from the illustrations in FIGS. 2 to 4.
  • the two inclined walls have a different angle of inclination. The slipping of the dry mortar is guaranteed.
  • the storage container 3 has a level indicator.
  • This storage container 3 also serves as a transport container.
  • a conveyor device 4 with a screw conveyor 5 is arranged in the bottom region of this storage container 3.
  • This screw conveyor 5 is driven by an electric motor 6, which is located in the axial direction of the screw conveyor 5 below the hopper slope of the storage container 3 and in particular is located within the circumferential contour of the frame 1.
  • This screw conveyor 5 opens into an interchangeable metering tube 7 with a metering screw 8, specifically following an opening 9 formed laterally in the storage container 3.
  • a mixing device 10 with a mixer tube 11 with a mixer shaft 12 therein is fastened to the opening 9.
  • the mixer tube 11 is further provided with two water inlets 13. The corresponding water connection lines are not shown.
  • the upper side of the storage container 3 also has a cover 14 which closes a corresponding opening 15 on the upper side of the storage container 3.
  • the mixing device 10 with the mixer tube 11 and the mixer shaft 12 located therein is removed and fastened below the hopper slope of the storage container 3, as indicated in FIG. 3. All necessary components are therefore housed in the device with e-pallet size for transport or operation. In particular, there are no protrusions during transport. In addition, optimal space and weight utilization on transport vehicles is guaranteed. Due to a low center of gravity and a constant cross-section, no transport lock is necessary.
  • the entire mortar mixing machine is set up at the required location, and the mixing device 10 is fastened to the opening 9 of the storage container 3 by means of a closure clamp 16, as can be seen in particular in FIG. 6.
  • the mixer shaft 12 is also coupled to the screw conveyor 5.
  • the water pipe is connected to the water supply 13.
  • the screw conveyor 5 is set into a rotary movement by means of the electric motor 6.
  • the drive motor can be removed via a quick release and a swivel joint.
  • the dry mortar is fed through the screw conveyor 5 to the metering screw 8.
  • the metering screw 8 conveys a constant amount of dry mortar into the flanged mixer pipe 11 of the mixing device 10.
  • the required amount of water is supplied to the mixer pipe 11 through the installed water metering system.
  • the mixer shaft 12 located therein works the mixture into wet mortar, which is discharged through the mixer pipe opening.
  • the water supply is controlled by means of a solenoid valve which is coupled to the control of the electric motor 6.
  • the mortar mixing machine can work fully automatically, with a sensor / pushbutton taking control of the required wet mortar, which can be placed in any mortar container or pump. Operating personnel are therefore not required.
  • the mixer pipe 11 has to be dismantled and rinsed with water.
  • the dry mortar in the storage container can remain there or is spread out through an emptying opening. If only dry mortar is required for processing, only the water supply has to be switched off.
  • the mortar mixing machine can be transported with all standard lifting trucks, forklifts and cranes.
  • the adherence to the Euro pallet dimensions (80 x 120 cm) ensures optimal utilization of the truck loading areas as well as high shelf storage capacity.
  • the mixer can be transported from all sides with all industrial trucks. In internal logistics, it can be transported with a roller conveyor and chain conveyor for automatic filling. Due to the low center of gravity, an additional transport lock is not necessary.
  • the mixing and electric drive can be easily dismantled for quick cleaning and emptying. Finally, the mixer can also be used in the rain without additional cover.
  • FIG. 7 shows the further development of the mortar mixing machine according to the invention.
  • the mortar mixing machine itself does not differ from that as has been shown in FIGS. 1 to 6 and has been described accordingly.
  • the difference consists in an additional refill container 17, which can be placed on the frame 1 of the actual mortar mixing machine, as can be seen in FIG. 7.
  • This refill container 17 has a corresponding cross-sectional shape suitable for pallets.
  • the refill container 17 has an opening 18 on the underside. This lies above the opening 15 of the storage container 3 after the corresponding cover 14 has been opened.
  • the connection between the refill container 17 and the storage container 3 takes place via a connecting line in the form of an accordion-like tube. This is fixed at the opening 18 of the refill container 17 and is flanged accordingly after pulling down on the opening 15 of the storage container 3.
  • This embodiment of the mortar mixing machine in FIG. 7 with the extension according to the invention with a refill container 17 in a first version works as follows:
  • the refill container 17 can be placed on the frame 1 in the manner shown. The connection is made via the connecting line 19 to the storage container 3. If necessary, the dry mortar located in the refill container 17 can then be opened into the storage container 3 by opening a corresponding flap. After the refill container 17 is empty, it is removed and, if necessary, replaced by a filled one. Thus, by combining the storage container 3 with the refill container 17, the supply of dry mortar can be expanded to over 2 tons.
  • the refill container 17 is designed as a flexible container which can be suspended in a frame 20 which can be fastened above the storage container 3.
  • This flexible container for bulk goods is usually used as a replenishment unit from the production site to the construction site, whereby it consists of a light-resistant and waterproof material and has the great advantage that it has only low return transport costs for refilling when folded, the useful life being about 5 years lies.
  • a transition piece 21 is placed on the storage container 3.
  • the outlet hose 22 of the flexible refill container 17 is double and protrudes into the interior of the transition piece 21 and on the other hand it is placed over the transition piece 21 on the outside. Slipping of the outlet hose 22 on the transition piece 21 is prevented by means of a bag buckle 23.
