Definitions

  • the invention concerns means and process for automatic color­ing of concrete, comprising at least one conveyor belt with balance, combined with batchers with hoppers, having its dis­charge side positioned on a container with mixer to which leads at least one water supply channel and at least one drain chan­nel on which at least one vacuum pump is positioned.
  • the first, which are used to obtain the colors red, yellow, black, brown and their shades, and the second, which are used to obtain green, and at any rate inorganic synthetic pigments in general, are substantially added to the cement and aggre­gates directly in the concrete mixers.
  • the dry oxides in powder are ad­ded by hand on the basis of volumetric evaluations and measure­ments. This method of proceeding is, however, very empiric and the chromatic result depends exclusively on the experience of the operator who prepares the mix.
  • Another problem consists in the fact that, in the dry mixes, it is impossible to completely and optimally exploit the oxides as the particles, besides dispersing easily in air, are not homogeneously fixed with those of the cement.
  • the ox­ides are prediluted in water by the producing companies; this system, although it permits a better yield and homogeneity of the mixes, also presents some particular problems, first of all the fact that the prediluted products are packed in drums, or at any rate very bulky containers, for which storage is necessary, with consequent increased costs of packing, trans­port, storage and of any recycling or disposal of the throw­away containers.
  • Another problem consists in the fact that the prediluted ox deeplyides create particular pollution problems, as, once a change of color is required, it is necessary to wash all the pipes, pumps and plants in general, with subsequent drainage of the water in sewer due to the fact that it is difficult to work in the presence of purification systems.
  • Another problem consists in the high costs of the products as fluidizing and deflocculating additives are present in them to prevent the decantation of the oxide particles and keep them suspended.
  • the object of the present invention is to elminate the above problems.
  • the invention solves the problem by means of means and process for automatic coloring of concrete, through which the following results are obtained: the oxide mixes are produced automatically, with precise, re­petitive batches; the predilution of the oxides is carried out inside a container with mixer in which the water has also the subsequent function of washing of all the parts that have come into contact with the products; the prediluted oxides are sent automatically to the concrete mixers in which the cement and aggregates are already being mixed; subsequently, after the mixing of the cement-aggregates with the prediluted oxides, a further batch of water is sent into the container with mixer, necessary to complete the total, final mixing, which operates a washing action of all parts.
  • the advantages of the present invention mainly consist in the fact that, besides the homogeneity and uniformity of the mi­xes, it is possible to vary automatically the quantity of coloring oxides and mix them together to obtain any special effect, e.g. streaks and imitation of colour which are ob­tained in the baking of brick products, and to obtain con­stant, optimal chromatic yields of colour.
  • Another advantage consists in the fact that the quantities of coloring oxides are accurately controllable by the pro­grammed weighing systems.
  • the microbatchers (2) can be programmed in opening and closure on the basis of the pre-established mixes.
  • the microbatchers (2) discharge in the underlying conveyor belt (3) the desired quantity of product contained in the corresponding loading hoppers (2′). Accor­ding to the color programmed, on the conveyor belt (3) can be discharged oxides from one or more microbatchers (2), whose opening and closure is governed by the quantity of pro­duct discharged, weighed directly by the underlying system (5).
  • the conveyor belt (3) discharges everything into a container (6), preferably constructed in stainless steel, in which is positioned a mechanical mixer (7) with motor (8).
  • the mixer (7) is equipped with a plurality of rotating blades positioned at different heights, preferably but unbindingly constructed in PVC or similar materials.
  • the oxide powder/powders are mixed and prediluted in a pre-established batch of water and re­gulated automatically according to the program established previously and inserted in the operator's control computer.
  • the water is inserted in the same container (6) through the channel (9).
  • the opening and closing of the feed valve (10) of the water is regulated automatically by means of the programmed computer.
  • the concrete mixer needs water and it reaches it through the drain pipe (11 ) of the container (6).
  • the first water that reaches the concrete mixer is that in which the coloring oxides have already been pre­diluted.
  • this second batch of water is discharged from the chan­nel (9) through the valve (10); before reaching the concrete mixer to complete preparation of the colored concrete, it is discharged in the container (6) exercising a washing action, which continues during discharge through the valve (12), the pump (13) and the drain pipe (11).
  • the feed valves (10) and drain valves (12) are preferably of pneumatic type, while the circulating pump (13) is preferably of pneumatic type with diaphragm.
  • the colored concrete is ready to be discharged from the concrete mixer on the belts, towards vibrating forms and to the presses for the formation of the finished products, while the mixing and predilution plant of the colored oxides is ready to be re-used according to any other formula and/or color or shade.
