Definitions

  • the invention relates to a method for producing a mixture of several components, for. B. a building material mixture or the like. Its individual components are woven and / or metered and then broken into a mixer, the mixing components being dry and of the same and / or different particle size, optionally at least partially powdery and at least one mixing component in relation to another is present in small quantities.
  • the invention further relates to a device for filling a mixer with mixing components, in particular a building material mixture, in which a mixture component is provided in only a small amount, the device preferably having funnel-shaped weighing and / or loading containers with metering devices or the like for the mixture components and has a feed from the feed container or containers to the mixer.
  • the above-mentioned method consists above all in that the mixture component, which is present in small quantities, is arranged under or in front of at least part of another mixing component when it is fed to the mixer and is covered by this other mixing component.
  • the component of the mixture that is completely in the mixer should occur, the connection between the weighing or loading container then passes through when the full cross section of this connection is still filled with material, so that an opposite flow of displaced air is not possible. Then, when the last material from a feed container filled in this way runs into the mixer, the component, the amount of which must not be falsified, is already completely in the mixer.
  • the mixing component is filled into a loading container, in particular a weighing container, and the mixture component present in small quantities and / or in powder or dust form or, if appropriate, lighter is covered by at least one further mixing component in the loading container. It is advantageous if at least a first layer of a mixture component, preferably in a larger amount, is poured into the feed container, if the mixed component of small amount and / or powder or dust form is then applied to this first layer and then at least one further layer of one Mixing component is layered over it. In this way, the mixture component to be dosed is enclosed on all sides and is filled into the mixture container all the more safely and mixed well. This additional substance is already arranged in a metered form between further mixture components. In addition, there is the additional advantage that, in the case in which the closure member of the weighing container is not dust-tight, a part of a mixture component which is only present in small quantities does not already exist can escape from this container or complex sealing measures are required.
  • the mixture component which is present in a small amount in particular, can be arranged within the loading container lower than half the height of its total filling and / or below at least half the total amount of the other mixture components. Even if the mixture runs out of one side of the weighing container into the mixing container, this ensures that parts of the mixture component, which is only present in small quantities, cannot be blown back in the last filling phase.
  • the method according to the invention can be used particularly advantageously if at least one additive, preferably in powder or dust form, is introduced as a mixture component in the feed container, which is covered and / or enclosed with preferably heavier and / or larger grains of other mixture components.
  • a powdery or dusty component would be particularly exposed to the risk of partial pressure back from the mixer container to be blown.
  • a device can be characterized in that, above at least one first loading or weighing container, a second weighing or loading container is preferably provided for the mixture component to be mixed in a preferably small amount, preferably an additive or the like, the outlet of which in the first Feeding container leads to the opening of the second loading container being able to be opened at least in part before the first loading container is loaded, with at least part of the further mixture constituent to be metered by the latter.
  • Such a device and the timing of the opening of the outlets of the charging container ensures that only a small amount or powdery additive or the like enters the main loading container before it has taken up all the mixture components present in large quantities, so that the aggregate or the like is covered in any case after the pre-metering with further mixture components.
  • the second loading container can be smaller than the loading container into which its outlet opens. This saves space and takes into account the fact that the mixture component to be covered is generally only provided in a small amount.
  • a device designated 1 as a whole is used to produce a mixture, e.g. B. a dry building material mixture, such as. B. dry mortar.
  • a mixture e.g. B. a dry building material mixture, such as. B. dry mortar.
  • it has a mixer 2 within a mixing container 3 and funnel-shaped weighing and loading containers 4 and 5 for metering the mixture components, and a feed 6 to the mixing container 3.
  • the second loading container 5 is for a mixed component present in a smaller amount, e.g. B. provided an aggregate, which, for. B. could be powdery.
  • the outlet 7 of the second hopper 5 opens into the first feed tank 4 and the opening of this outlet 7 of the second hopper 5 is effected temporally before the feed of the first feed container 4 with at least a part of the of this further to be metered blend components.
  • FIG. 1 It can be seen in FIG. 1 that further feed devices 8 and 9 open into the first loading container 4, by means of which substantially larger quantities of mixture constituents 10 can be fed.
  • the components 10 are shown schematically as relatively coarse parts, while the aggregate 11 is drawn as correspondingly small parts.
  • the control for the opening of the second feed container 5 and the control for the feed device Lines 8 and 9 for the remaining mixture components to the first loading container 4 is not shown in detail, but is provided in the form that the second loading container 5 is opened with the other components and, if possible, emptied before the end of the loading of the first container 4. This results in the storage of the mixture component 11 from this container 5 between the other components 10, as shown in FIG. 4.
  • this relatively easily swirlable component 11 is taken along and transferred into the container 3 before air in the last emptying phase of the container 4 according to the arrow Pf 1 in FIG. 3 against the filling direction can flow back into this container 4 and blow back components. This could happen when the container 4 is filled according to FIG. 2 and is avoided by the invention.
  • a ventilation nozzle 13 can be seen on the loading container 4, and a further nozzle 14 can also be seen directly on the mixing container 3, on which, if appropriate, a further balance or the like.
  • Loading device can be arranged.
  • a ventilation nozzle 15 with a filter 16 arranged above it, through which a large part of the air in the mixing container 3 is to escape when filling the mixture components 10 and 11. Due to the filter resistance, however, a certain overpressure is nevertheless built up in the mixing container 3, which in the last phase of the filling according to FIG. 3 results in a partial air flow leads into the feed container 4 against the filling direction.
  • the device according to the invention now makes it possible, when loading the mixer 2 and its container 3, with mixing components 10 and 11 in such a way that the component 11, which may be in the form of a dust or powder, is present in a smaller amount in the loading container 4, among other things, preferably heavier and / or larger components of at least one other mixing component 10 and is covered at the top by this mixing component.
  • Fig. 4 shows that the additive 11 is arranged within the loading container 4 on a base of other components of the mixture and the other mixture components are arranged both to the side of the additive 11 and above it, so that not only this component 11 is then completely in the container 3 is transferred when the air outlet according to FIG. 3 also takes place on the loading container 4, but mixing with the other constituents is also favored.
  • Fig. 4 also shows that the additive or mixture component 11 can be arranged within the first loading container 4 approximately under half the total volume of the other components.
