Definitions

  • the invention relates to a device for continuously mixing a mortar, in particular a plastering mortar or self-leveling screed, with water and pumping the mixture, which has a mortar container, a mixer, a pump and a delivery hose in succession.
  • the dry mortar In order to make the plaster mortar more productive and to introduce porosity into the plaster to improve the thermal insulation, the dry mortar usually already contains surface-active agents. These are intended to promote the mixing of the air entering the mixer with the dry mortar into the mixture. The proportion of air mixed in remains low. Most of the air escapes upwards.
  • the invention has for its object to better control the air content of the mortar-water mixture in a device of the type mentioned.
  • this purpose is achieved in that a vessel provided with a stirring tool is connected between the mixer and the pump, in which the mixture has a free surface in the air which is moved by the stirring tool.
  • the same mortar-water mixture absorbs far more finely divided air over the free surface in the air than is possible with the aforementioned types of air introduction.
  • the agitator does not even need to blow in the air. It can stay under the surface and only needs to create movement on the surface.
  • the addition of surface-active agents as pore formers can even be reduced.
  • the liquid screed provided with defoamers defoams on the free surface. Most of the unwanted air escapes.
  • the vessel has in its lower part the shape of a cylinder section, the jacket of which merges into upwardly diverging side walls on both sides, and the lower part is supplemented at its two ends to form a circular cross section, so that connection openings are formed here are to which on the one hand a drive for the stirring tool or a feed for the mixture with a drive for the stirring tool and on the other hand the pump can be attached, and above the connection openings there are diverging end walls; axially between the connection openings extends a shaft which forms the stirring tool and is equipped with stirring arms.
  • the vessel is designed not only for the immediate fulfillment of its task, but also for the handling of the device.
  • the device can be assembled from the vessel, the pump, the mortar container and the mixer, the latter two individually or as a unit.
  • a silo as a mortar container to which a mixer is attached.
  • the height ratios will then make it convenient to empty the mixer from above into the lower vessel.
  • the drive for the stirring tool is then attached directly to one of the connection openings.
  • a funnel-shaped mortar container made of sacks or pneumatically conveyed is carried out as a unit with the mixer and be attached to the connection opening of the vessel via the aforementioned feed for the mixture, the drive for the stirring tool reaching through it.
  • the above-mentioned shaft equipped with agitator arms expediently extends further through the feed and is equipped with agitator and / or conveyor blades within it.
  • the agitator arms can also be designed as conveyor blades at the same time.
  • the shaft forming the stirring tool with the stirring arms is at the same time the drive shaft of the pump and on the one hand by its coupling with the pump and on the other hand by its coupling to the drive.
  • the pump will generally be an eccentric screw pump, the rotor ends of which move somewhat eccentrically, the shaft coupled to the front rotor end, which is only supported by this and by its other coupling, can follow the eccentric movement. This applies to the case of the drive directly attached to the vessel as well as the case of the feed through which the shaft extends to the drive.
  • the drive for the stirring tool or the feed on one side and the pump on the other side can expediently be attached to the vessel, preferably mirror-symmetrical with respect to its central cross section, by means of clamps.
  • the drawing shows an embodiment of the invention. It shows a vertical longitudinal section through a device for mixing a mortar with water and pumping the mixture.
  • a horizontal cylinder 1 and a T-shaped vertical cylinder 2 assembled with it with a funnel 3 on upper end form a rigid unit that can be moved on two wheels 4.
  • a funnel upper part 6 is seated on the funnel 4 with an easily detachable flange connection 5.
  • a geared motor 8 is attached to the cylinder 1 by means of clamps 7 at one end of the horizontal cylinder 1.
  • the cylinder 1 is connected to a vessel 10 by brackets (not visible), at the other end of which a cam screw pump 12 is attached by brackets 11.
  • the entire device is supported on two feet 13 of the vessel 10.
  • the funnel 3 and the upper funnel part 6 form a mortar container 14.
  • a mixer 15 is set up with a mixing tool designed as a basket 16, from which a loosening spiral 17 projects upwards into the funnel 3.
  • the lower end of the basket is formed by a ring 18 on its underside which is designed as a toothed ring.
  • a correspondingly designed drive ring 19 of the geared motor 8 meshes with this.
  • the geared motor 8 also has a coupling 20 for connection to a shaft 21, in the form of a slot with a central broadening of a round cross section.
  • the shaft 21 is in the slot with a correspondingly round thickening of the tongue in cross section.
  • the shaft 21 is equipped with stirring and conveying blades 22 in the area of the horizontal cylinder 1 and with stirring and conveying blades 23 in the area of the vessel 10.
  • the vessel 10 has the shape of a cylinder section below the shaft 21. This is followed by diverging upwards Sidewalls. Together with end walls 24 which also diverg upwards, they give the upper part of the vessel 10 the shape of an inverted truncated pyramid. The end walls 24 are folded outwards at the bottom. There are connection openings 25 formed on both sides with a circular cross-section at the end. in addition to two mandrels 40 projecting rigidly from the vessel 10, on which the flange is suspended,
  • bow-shaped handles 33, a hose connection 34 at the end of the eccentric screw pump 12, an electrical connection 35 of the geared motor 8 and a water connection 39 of the mixer 15 are mentioned on the flanges 26, 28 and 32.
  • the mortar constantly refilled in the mortar container 14 is gripped in the funnel 3 by the loosening spiral 17, which prevents bridging here and at the same time pushes the mortar down into the mixer 15.
  • the water connection 39 entering water mixed through the basket 16 as a mixing tool.
  • a further mixing then takes place in the part of the horizontal cylinder 1 forming the feed 36 to the vessel 10 through the stirring and conveying blades 22.
  • the mixture is set into strong motion by the stirring and conveying blades 23. This continues up to surface 37.
  • air is taken up there.
  • foam is deposited.
  • the bend of the end walls 34 at the lower end forms a short tunnel 38 which becomes lower towards the connection opening 25 and in which the material can be attracted by the eccentric screw pump 12 without air being sucked in.
  • the pumping of the mixture through a hose attached to the hose connection 34 is then the usual one.
