Definitions

  • the invention relates to a device according to the Preamble of claim 1.
  • a device is known from EP-0051224.
  • the disadvantage of the known The device consists in the too short dwell time of the Mortar in the mixing chamber after adding water, whereby the mixing is incomplete. This is especially undesirable for finer mortars such as for example lime mortar, because then the mortar does not sufficient adhesive force developed.
  • This disadvantage is said to be resolved with the invention and the device therefore corresponds to the characterizing part of claim 1. This ensures that the Transport speed through the mixing chamber the supply of dry mortar is determined, whereby the mixing chamber fills up completely and the uniform mixing of the dry mortar with water is promoted.
  • the device is like described in claim 2. So that will achieves the torque required for mixing is as low as possible, so no difficult electrical connection for the drive means of the Mixer is needed.
  • the Device executed as described in claim 3. This ensures that the supply of Torque required by dry mortar as low as possible is what is beneficial.
  • the Device executed as described in claim 4. This ensures that the material that is in shape a strand is pressed through the mixing chamber from Wiper is turned off and through the discharge opening falls down.
  • the Device as described in claim 5 executed. This means that even with an irregular water supply achieved a constant water supply in the mixing room, which improves the quality of the mixed mortar becomes.
  • the Device as described in claim 6 executed. This allows the moisture in the mortar to stick to the The wishes of the user can be adjusted.
  • the device executed as defined in claim 7. This will an easily adjustable water supply in a simple manner reached.
  • Figure 1 shows a silo 4, in the dry mortar is stored, the dry mortar after Turn on mixed with water and to a place is transferred to which the mortar is used.
  • silos 4 are set up on building sites, and in situations where the water and Power supply simple in most cases is executed.
  • the dry mortar is in one closable funnel 7, which is sealed airtight can be stored to prevent the Dry mortar gets wet through the air humidity.
  • the closable funnel 7 has a lid 6 and stands on extendable feet 9.
  • the dry mortar is if necessary in a metering chamber 11 and from there into a Mixing chamber 12 transfers where the mortar by mixing is made ready for use with water. For the Transport from the funnel 7 into the metering chamber 11 a vibrator 3 can be used.
  • the mortar mixed with water is made from the Mixing chamber 12 pressed and falls through the Discharge opening 13 in a wheelbarrow, which under the Discharge opening 13 is made.

  • Inner diameter of the tubular mixing space 24 from The strips 23 have an area of 28 x 8 and 175 mm a mutual distance a of about 50 mm, wherein in each average two strips 23 on each Shaft 22 are attached opposite.
  • a Scraper 25 attached to the shaft 22, the out the same strip is formed and that on the plane the axis of rotation is mounted so that it turns on runs along the inner wall of the mixing space 24.
  • the Scraper 25 scrapes this through the mixing chamber 24 Discharge opening 13 pressed material, so that this can fall down through the discharge opening 13.
  • the dry mortar is in the funnel 7, the with Lid 6 (see Figure 1) and closure 14 closed can be. After opening the closure 14 and possibly after activating the vibrator 3 falls the dry mortar in the dosing room 15.
  • the drive 10 is turned on and turns the shaft 22 for example at a speed of 20 Revolutions per minute.
  • the dry mortar is then in pressed the mixing room 24. In the mixing room 24 there is water through a located in the vicinity of the metering opening 21 Water connection 29 metered.
  • dosing chamber 11 and mixing chamber 12 cleaned.
  • the closure 14 is opened with a lever 35 closed, and as much material as possible with the Metering vanes 18 from the metering chamber 15 transported.
  • a lid 19 is opened and the dosing chamber 15 cleaned.
  • FIG 4 shows schematically how this is realized.
  • a Water supply 32 fills a water tank 31 over Valve 33.
  • Valve 33 has a float 34 connected, whereby the water level in the water tank 31st can be kept more or less constant.
  • the Water supply 32 pressure may fluctuate for example between 1.0 and 2.0 bar.
  • the water tank 31 is with the Suction side of a control pump 30 connected Pressure side is connected to the water connection 29.
  • the output of the control pump 30 is with that on the Switch box 8 attached adjustment knob 8a (see Figure 1) set.
  • the pump 30 has a fixed one Funding volume up and becomes adjustable Speed driven by an electric motor that is fed by a frequency converter.
