Definitions

  • the invention relates to a method for the provision of pasty building materials, in particular mortar on construction sites. - The invention further relates to a device for performing the method according to the preamble of (device) claim 3.
  • Factory-made mortar (or similar pasty substances) is transported from the production site to the construction site to be processed using mortar silos.
  • the production facilities can only produce the mortar with a standard consistency and the respective processing method is not known (e.g. the temperature of the substrate, the processing mentality of the craftsmen, etc.)
  • the consistency of the mortar supplied must be worked on site. This can result in poor plaster quality.
  • additional water can be fed into the container beforehand by means of a bucket or hose, but afterwards a laborious stirring with a hand mixer must be carried out. If too much water is accidentally added, the mortar becomes unusable.
  • the object of the invention is to create a method for the provision of pasty building materials, in particular mortar on construction sites, with which the consistency of the pasty building material to be processed can be improved; a device for carrying out the method is also to be created.
  • the paste-like building materials in particular paste-like mortar
  • the idea of the invention is to additionally add water at the location of the processing of the mortar, so as to ensure the consistency of the mortar readjust and so to ensure the fine logistics from the mortar silo to the facade through this subsequent water supply on the construction site.
  • the mortar produced in a standard consistency can be adapted to the respective processing method by subsequently adding water, for example the temperature of the mortar substrate and the processing mentality of the craftsmen.
  • the desired mortar consistency can be produced automatically and with little effort.
  • the development according to claim 2 has the advantage that a continuous process with a continuous supply of pasty building material, in particular mortar in the desired consistency is possible.
  • the device-related technical solution to the problem is characterized by the features in the characterizing part of claim 3.
  • the pasty building materials in particular pasty mortar
  • the idea of the invention consists in the fact that the mortar is processed at the place of processing in the course of removal from the storage container additionally with water to adjust the consistency of the mortar.
  • the integrated mortar pump unit thus has an additional water injection with an upstream water metering system in order to ensure the fine logistics from the mortar silo to the facade through this subsequent water supply on the construction site.
  • the development according to claim 4 has the advantage that the pasty building material can flow down directly into the feed and mixing pump, where the additional water is then added.
  • All units of the feed and mixing pump are accommodated in the elongated, tubular part of the development according to claim 5.
  • the electric motor is preferably located at the end of the tube opposite the outlet end.
  • the feed and mixing pump is located below the storage container and does not exceed its basic dimensions, transport damage is avoided and easier handling is ensured.
  • the conveying and mixing elements according to claim 7 can be optimized with regard to their application.
  • the conveying and mixing elements can have a common shaft, which overall results in a simple construction.
  • the mixing zone is approximately in the last third of the total zone.
  • the mixing elements can be designed in a hedgehog shape.
  • the feed and mixing pump has a specially designed mixing zone, to which the mortar to be changed is fed out of the delivery zone.
  • the hedgehog-shaped mixing tools on the hedgehog shaft in the last third of the total zone formed from the conveying zone and the mixing zone ensure that the water is quickly mixed into the mortar.
  • the mortar which has a different consistency, leaves the feed and mixing pumps with a high degree of uniformity and can be processed from there.
  • the consistency-modified mortar is pressed through the third discharge zone, thereby increasing its uniform consistency.
  • the discharge for the pasty mortar then follows the discharge zone. For example, it can be removed via a hose.
  • a further preferred development of the invention proposes claim 12.
  • the requirement in the method according to the invention for optimizing the consistency of the mortar is that in a mortar silo with a volume of 1 to 2 m 3, only very small amounts of water of approximately 10 to 20 l / hour are required.
  • the installed water metering system is equipped with very small needle valves on flow meters, with which it is possible to supply the small amounts of water to the mortar passing through the feed and mixing pump.
  • the water is automatically fed through a hose through the water metering system and a switching unit during the pumping process.
  • the silo for mortar has a square frame 1, in the interior of which a funnel-shaped storage container 2 is arranged. This reservoir 2 can be loaded with the mortar 1 from above. At the bottom there is a round outlet opening, which can be closed by means of a flap,
  • a feed and mixing pump 3 is attached to this lower outlet opening of the storage container 2 for the mortar.
  • This feed and mixing pump 3 has a trough-shaped housing 4 with an essentially V-shaped cross-sectional profile below the outlet area of the storage container 2, which tangentially merges into a partial cylinder jacket surface in the lower area, starting from the inclined side walls.
  • a tube 5 connects to one end of the housing 4.
  • Another tube 6 is flanged to this.
  • a discharge opening 7 is located at the front end thereof.
  • a shaft 8 is located inside the housing 4 and the two tubes 5, 6. This shaft is driven by an electric motor 9, which is located on the other side of the housing 4.
  • the feed and mixing pump 3 is divided into three zones, namely first into a first delivery zone 10 in the area of the funnel-shaped housing 4, a mixing area 11 in the area of the tube 5 and a discharge zone 12 in the area of the second tube 6.
  • the shaft 8 of the delivery zone 10 carries wing-shaped conveying elements 13 which are inclined with respect to the transverse plane. These wing-like conveying elements 13 have a relatively large width, ie they extend over the entire diameter of the shaft 8, as can be seen in FIGS. 3 and 4.
  • the shaft 8 has mixing elements 14 which are designed as hedgehog-shaped wings. These wings are narrower than the wings of the conveyor elements 13. The width is approximately half the diameter of the shaft 8.
  • the blades of the mixing elements 14 are inclined with respect to the transverse plane of the shaft 8.
  • the special thing is that for some of the mixing elements 14 the angle of attack is directed in the opposite direction. This can be seen in FIG. 4 for those mixing elements 14 which are directed towards the viewer from the viewing plane. It can be seen that, seen in the direction of transport, the first three wing-like mixing elements 14 are positioned opposite to the conveying elements 13, while the remaining two mixing elements 14 have the same angle of attack as the conveying elements 13.
  • the tube 5 of the mixing zone 11 also has a water supply 15 on the upper side with an upstream water metering device 16.
  • the housing 4 has a further water supply opening 17 for cleaning purposes.
  • the mortar silo works as follows:
  • the mortar produced in the manufacturer's plant with a fixed standard consistency is transported to the construction site in storage container 2.
  • the mortar is discharged from the storage container 2 by means of the feed and mixing pump 3.
  • a very small amount of water is supplied to the mortar in the mixing zone 11 via the water feed 15.
  • the upstream water metering device 16 is used, which is equipped with very small needle valves on flow meters. The reason is that a very small amount of water of about 10 to 20 l / hour is required. This small amount of water is injected into the mixing zone 11 via the water feed 15 and is thus fed into the mortar. Mixing takes place by means of the hedgehog-shaped mixing elements 14.
  • the mixing elements 14 are oriented in the opposite direction to the wing-like conveying elements 13 on the shaft 8, so that they produce a slightly opposing conveying effect, which overall increases the degree of mixing.
  • the mortar with the desired consistency After passing through the discharge zone 12, the mortar with the desired consistency then reaches the outlet opening 7. From there, the mortar can be discharged via a hose at the desired location.
  • the method according to the invention ensures that the mortar delivered in a standard consistency can be optimized in terms of its mortar consistency in a technically simple manner.
