Definitions

  • the present invention relates to certain new and useful improvements in mixing machines and more particularly refers to fully automated mixing apparatus with continuous action for the production of portland cement mortars and foam concretes with different qualities and volumetric weights.
  • portland cement mortars mixers The use of portland cement mortars mixers is known in the prior art. Initially they were manually operated, and later with motor drive. Currently, there are many varieties of mortar mixers with intermittent /USD534551S1/ and with continuous action / US2756975A /. The production of foam concrete is carried out by mixing in various machines of pre-prepared mortars and foam. Mortar mixers are used to prepare special portland cement mixtures for 3D printing of buildings. Currently available mixers with continuous action of mortars have disadvantages, such as manual adjustment of raw material parameters, difficult and slow or impossible change of the recipe and a high probability of human error.
  • the first object of the present invention is to provide a fully automated continuous mixer of portland cement mortars with different qualities and volumetric weights. It uses several types of dry materials and several types of liquid chemicals. In its hull, there is a foam generator to add foam to the mortars for the production of foam concrete.
  • Another object of the present invention is for the mixer to continuously change the production of various recipes of mortars and foams, as well as automatically switching from portland cement mortar production to foam concrete production and back to portland cement mortars.
  • the present invention aims at eliminating the aforementioned disadvantages in the prior art and its main object is to provide a fully automated mixer, characterized by a new mixer for portland cement mortars and foam concrete having at least two hoppers for bulk dry materials, for example Portland cement, gypsum, lime, ready-made dry mixes and dry sand.
  • a dispensing auger driven by a stepper motor, which feeds a set amount of dry materials from the hoppers into a new dry mixer with wetting injection nozzles located around it.
  • the wetted mixture is stirred in a new mixer and enters a mixer of the construction mixture and a mixer with foam concrete.
  • Peristaltic hose pumps driven by stepper motors, precisely supply water needed for portland cement mortars and foam.
  • the object of the invention is the uninterrupted production of various recipes of mortars and foam concrete and is solved by changing the revolutions of stepper motors driving the augers and peristaltic hose pumps.
  • FIGS. 1-4 a preferred embodiment of the automated mixing apparatus for the production of portland cement mortars and foam concrete, which the present invention is shown.
  • FIG. 1 shows the new apparatus. It has a self-supporting structure of three parallel vertical sheet metal planes, which are reinforced from above by three frames to form a first hopper (1) and a second hopper (2), which is smaller and has space for a control unit box (3). At the lower end, the structure is reinforced by two sector-cut support pipes (4), which are auger beds.
  • FIG. 2 shows the new dry mixer (6) and a mixer for dry mixture with water (9).
  • the two augers (5) and (7) mix the dry materials from the hoppers (1) and (2) in the common body of the dry mixer (6), dropping down the dry mixture is wetted by circumferentially located nozzles.
  • the closest known patent for such wetting is WO2018112561 .
  • a stirrer mixes wet material in the mixer for dry mixture with water (9), and in a mortar mixer (10) and foam from a foam injector (11).
  • the mortar mixer (10) is disassembled from the mixer for dry mixture with water (9), leaving the stirrer in place to be easily cleaned.
  • FIG. 3 shows a new drawer-type cantilever structure (13).
  • the mixer for dry mixture with water (9) and the mortar mixer (10) is attached to the cantilever structure (13).
  • the new cantilever structure (13) moves along the lower edge of the self-supporting structure of the mixer for Portland cement mortars and foam concrete (10). This allows the mixer for dry mixture with water (9) and the mortar mixer (10) to be removed from the housing to be cleaned, as well as to remove remaining dry material from the hopper (1) only by starting the auger (5) as well as from the hopper (2) by starting the auger (7).
  • FIG. 4 shows a cooler (14) of the control unit (3), which is made of a ribbed aluminum plate (15) with attached serpentines and on which computer processors and a cooling radiator (16) are mounted directly.
  • the cooler is mounted on the rear wall of the control unit box (3).
  • a peristaltic hose pump (17) introduces the water for the production of solutions through the cooler (14), and part of the water passes through a pump into the cooling radiator (16) and returns back to the cooler (14).
  • a system of peristaltic hose pumps (17) are installed in the space next to the sloping side wall of the hoppers.
  • the main pump supplies water to wetting injection nozzles, separate peristaltic hose pumps (17), pour chemicals into the water through a soothing vessel of the main pump and to a foam generator (18). All chemical additives are in separate containers mounted on the housing.
