Definitions

  • the present invention relates to an improved concrete-mixing process and a relative plant with the mixing of components.
  • the known existing concrete-mixing plants are generally characterized by the use of pre-established quantities of components by weight or volume, which are such as to provide a reasonable quantity of mix at the end of the mixing process.
  • the established quantities of components are provided and are then introduced into the main machine called “mixer” in order to homogenize the mixture of components as much as possible with water to obtain the final mixture, called concrete mix.
  • Both the inert starting materials and their proportions can vary, as also the sequence, i.e. the order with which the components are put together, but above all the homogenization of the mix must be well supervised before the mixing water is added.
  • the general objective of the present invention is therefore to provide an extremely simple plant with easy control of the specific variables in order to obtain a continuous and reliable mixing system.
  • objectives of the invention are to identify a plant and process for obtaining optimum characteristics of the product obtained, easy calibration, simple handling of the start-up and shut-down, to be effected rapidly and/or instantaneously.
  • the embodiment, object of the present invention is substantially characterized in having identified means and systems for the production of a controlled, constant and perfectly homogeneous mix of all the starting components except for water, and subsequently obtaining, by means of a continuous mixer with an open Archimedean screw, the continuous mixing of the product, mixed in the dry state with water in the desired ratio and proportions.
  • the preferred industrial application thus described also consists in availing of a plant provided with all the necessary means for the variable weight measurement of the single materials in order to calibrate the proportions and ratios, with particular reference to the water/cement weight ratio, as desired.
  • the plant described consists of a series of containers 11, 12, 13, 14, etc. or deposit areas 15, 15', etc. in which the various raw materials in the form of dry powder, such as pigments, fibres, accelerators, fluidifiers, cement, sand, other materials suitable for the cement mix, are contained or added.
  • the containers 11, 12, 13, 14, etc. are equipped with extraction screws 16 (alternatively belts) which selectively feed them into a weighing and/or dosing area 17 and subsequently into a main hopper 18.
  • extraction screws 16 alternatively belts
  • the various raw materials are fed by gravity fall from the Archimedean screws 16 in the weighing and/or dosing areas 17 or directly by means of conveyor belts 19, 19', etc. for the sand or one or more Archimedean screws 20 for the cement to the main hopper 18.
  • the feeding to the main loading hopper 18 is effected, for example, in a time order according to the following sequence.
  • Sand having various particle-sizes, is fed first, followed by cement and subsequently various basic components such as colour, fibres (to give the mix tensile strength).
  • said sequence can also envisage the addition of other additives such as fluidifiers, accelerators (which, always in the dry state, can be useful for the final mix in relation to the uses and end-product desired).
  • additives such as fluidifiers, accelerators (which, always in the dry state, can be useful for the final mix in relation to the uses and end-product desired).
  • the whole combination of components is discharged from the loading hopper 18 into a mixer 21 which is in continuous movement.
  • the discharging is effected by the opening of one or more outlet mouths 22 whose opening is controlled by rapid opening valves 23, for example of the snare type.
  • the continuous mixer 21 is produced, for example, with high speed rotating blades 24, always in motion, so as to homogenize and uniformly disperse the combination of various components discharged. Once the weighed or volume dosed single components have been charged into the mixer, they are amalgamated in the dry state for a certain period corresponding to the required cycle time.
  • the continuous mixer 21 unloads the homogenous compound obtained by the opening of a door 25, for example of the twin-valve type, which allows the material to drop into a further hopper 26.
  • This compound or mix, contained in a further hopper 26, is fed in continuous by means of a belt 27 to a simple continuous screw mixer-feeder 28.
  • the mixing water is also introduced into the continuous screw mixer 28, by means of pulverizing nozzles 29, and can be continuously controlled and regulated by the plant operator by means of a control device 30 equipped with instantaneous visible control of the quantity of water supplied.
  • the only part of the mix, in fact, which must be rapidly eliminated is that which is already wet and contained in the continuous screw mixer 28.
  • This elimination can be effected by means of an opening 32, selectively openable, which allows the discharge of the mix contained in the mixer 28 into a trolley or container 33.
  • the whole mixer 28 can be moved with one of its outlet openings 34 from the position above the extruder 31 to a position above the trolley 33, as it is situated on a trolley equipped with wheels 35.
  • a first area or dry mixing phase of the components batchwise with doses of the components which can be easily established in relation to the demands.
  • a second area or hydration phase of the compound thus obtained in continuous, with water inserted to obtain the mix only at the last moment.
  • the present invention is consequently particularly important in the field of automatic mixing plants for the production of extruded products, such as, for example, tiles made of coloured cement.
