Definitions

  • the invention relates to a device for the construction site Production of pumpable mortar compounds.
  • Such a device is known from DE 43 18 177 A1.
  • the device disclosed in this document comprises one Mixing device in which dry material and water Mortar masses are produced.
  • the mixer has on the feed side, a filling funnel with a connecting piece for the supply of the dry material.
  • the hopper also has an upward one Vent pipe.
  • the invention has for its object this dust development and the dry material outlet at the device to reduce the above-mentioned genus.
  • the Vent pipe contains a hose, the inflow, end pointing towards the funnel with a sudden increase in air speed closes and its outlet end with the jacket of the Vent pipe is connected.
  • the essence of the invention is that the hose in particular retains dust and dry matter, caused by air blasts, when the supply is uneven of the dry material arise, get into the ventilation pipe. This largely prevents the vent pipe Dust clouds and dry material leak out, which the Pollute the environment.
  • the hose has one essentially freely hanging, inflow end, which closes when the air speed increases. This The process is reversible, i.e. the hose end opens, as soon as the respective air blast has subsided. Since it is on the The hose can not be flexible e.g. also through a rigid pipe with at the inflow end attached tabs to be replaced. Lay these tabs when the air speed increases via the pipe opening and hold back the dry material.
  • the inlet end of the hose in is advantageous Incised longitudinal tube direction (claim 2). At least they are two cuts, the end of the hose has several Rag or lamella, which are caused by the effect of Air blast more or less on top of each other and through the dry material transported into the vent pipe hold back.
  • the tube is preferably from a fabric (claim 3).
  • the hose jacket is advantageously air-permeable 4). This allows excess air to escape from inside the device be discharged even if the hose end is closed is.
  • the Hose over 50 to 70% of the length of the vent pipe (Claim 5).
  • the outflow end of the hose is advantageous attached to a piece of pipe inserted in the vent pipe the other end of which is directed downwards (Claim 6). At the downward end, a Discharge for low-dust discharge from not through the Hose held dry material connected his.
  • the device shown in the drawing consists of a mixing device 1 with a mixing shaft 2 and one the screw device 3 connected downstream of the mixing device 1.
  • the mixing device 1 and the screw pump 3 are coaxial one behind the other along a line falling in the conveying direction Axis and are arranged with a drive unit 4th driven.
  • the screw pump 3 delivers in the direction of schematically indicated hose line 22.
  • the device has an only schematically indicated chassis 5.
  • the Mixing device 1 is dry material via a hopper 15 fed that from a connector 14 from a storage container 13, e.g. a silo.
  • the funnel 15 is equipped with a level sensor 9, one controller 10, 11, if necessary one on the storage container 13 attached ventilation aid 12 activated.
  • the mixing device 1 has a water connection piece 6 equipped, which is connected to a water supply line 23 is.
  • the water supply line 23 comprises a metering device 7, connected to the local water network via a valve 8 is.
  • the hopper 15 is through a transverse wall 24 in the Rooms 16 and 17 divided.
  • the connecting piece opens into room 16 14 for supplying the dry material; from the Room 17 opens a vent pipe 18 in which a Hose 19 made of an air-permeable fabric is.
  • This hose 19 has in Fig. 1 in the direction of the hopper pointing free, open end; the opposite The end of the hose 19 is at an angled pipe socket 20, which is inserted into the vent pipe 18, attached.
  • One leg of the angled pipe socket 20 points towards the ground. There is a derivative on this leg 21 attached via which is not retained by the hose 19 Material is discharged with little dust.
  • the hose 19 is on his free end slotted several times, so that the end of individual Rag or lamella 25 exists.
  • Fig. 2 the e.g. if the supply increases suddenly state of the inflow side of dry material In the end.
  • This blast of air causes that the tabs 25 of the hose 19 more or stack less. This largely prevents Dust and dry matter in and out of the hose the environment can leak.
