Definitions

  • the subject of the invention is a device for manufacturing a self-hardening foam which finds its application in building, mining and the packaging industry.
  • This mixer of said known device also known as the dosing head, is connected to the pumps via various elements.
  • Changing the position of the piston of the distributors implies, on both sides, at the enclosure of the mixer, a simultaneous flow of the two components under recorded pressure which, under the effect of reciprocal shocks, mix and are discharged from this enclosure by a lower nozzle.
  • the air distributor opens the air valve, which allows the circulation of compressed air through the mixer enclosure.
  • the essence of the invention consists in changing the construction method of the mixer and the foam ejector.
  • the device according to the invention for manufacturing a self-hardening foam comprising a powertrain, two pumps equipped with suction and discharge lines connected to the mixer terminated by a foam ejector, is characterized in that the flow lines of the two components and air, are parallel to each other introduced into the bottom of the mixer, the rigid spumogenic part of which has the form of a tube, while the hardening part consists of a flexible pipe, advantageously of cloth with insert in plastic material, and in that the flow pipes for the spumogenic components and the area terminate at the bottom of the mixer, while the flow pipe for the foam curing agent passes through the entire rigid spumogenic part including the dispersing element, in particular the plastic wire strand, part of the enclosure of which is filled inside this part of the mixer, and finished only in the con soft pick.
  • FIG. 1 represents a view in longitudinal section through the mixer
  • FIG. 2 a view in transverse section through the rigid mixing part spumogenic.
  • the nozzles 1 and 2 of the flow pipes of the spumogenic components and of the air communicate with a metering part, not illustrated in the drawing, of the device for manufacturing the self-hardening foam, and fixed together in a parallel manner, and they emerge directly from a metallic bottom 3 of the mixer, the rigid spumogenic part 4 of which is constituted by a vynilite tube 5 with a length equal to approximately 10 diameters of the tube, aimed at the bottom 3.
  • a nozzle 6 of the curing agent flow line is also mounted parallel to the nozzles 1 and 2 also opens out at the bottom 3 of the mixer, but it is extended outside a dispersing element 7, in the form in particular of a plastic mesh strand, and it penetrates up to the hardening part 8 of this mixer, with a length of the order of 100 diameters, constituted by a flexible duct of canvas, fixed in a molded metal piece, being on one side the bottom of the tube 5 in vynilites, and on the other side e, a vacuum maintenance piece of the flexible pipe 9, the foam ejector of which is the end piece of this pipe 9.
