Definitions

  • the subject of the invention is an apparatus for producing and applying foam, in particular intended for degreasing and disinfecting premises in the food industry, as well as for all applications where the presence of foam is desired, such as cleaning. and dyeing textiles, cements and others.
  • the apparatuses hitherto used to manufacture the foams in question are complicated, expensive and involve complex adjustments.
  • the object of the invention is, above all, to remedy these drawbacks and to provide the user with simple, robust apparatus which is easy to adjust.
  • the mixing chamber is formed by two pipes forming "T", the bar of the "T” materializing the supply pipe for the compressed gas and the leg, the supply pipe for the liquid treatment product. , the diaphragm which is arranged in the supply pipe of the liquid treatment product being constituted by a washer.
  • a single enclosure is equipped with several sets of pipes forming the mixing chamber, these sets making it possible to simultaneously treat several rooms using foam produced using the liquid treatment product. kept under pressure in the aforementioned single enclosure.
  • This apparatus is made to understand an enclosure 1 comprising a filling opening 2 closed by a cover 3 and intended to contain under a determined pressure a liquid treatment product from which the foam to be prepared must be prepared, in particular on the parts of premises in the food industry to be degreased and / or disinfected.
  • the enclosure can be made of steel, stainless steel or any other metallic or non-resistant material, in particular the corrosive action of the liquids which it must contain.
  • the liquid treatment products contain one or more foaming surfactants adapted to the base or to the acid chosen and necessary for the generation of the foam.
  • liquid products can be prepared by dilution from concentrates containing the constituent substances except possibly the foaming agent which is added at the time of dilution.
  • They can also be prepared by dissolving the constituent substances in water in suitable proportions.
  • the liquid treatment product 4 is placed in the mobile enclosure 1 on rollers la and comprising a drain valve 16.
  • a pipe 5 comprising pressure reducing means 6 and adaptable to a source 8 of compressed gas.
  • the pipe 5 forms, downstream of the means 6, first and second pipes 9 and 10 respectively equipped with non-return means, in particular with non-return valves 11 and 12, and suitable for conveying the compressed gas respectively inside from the enclosure and to a mixing chamber 13.
  • the tubing 9 penetrates inside the enclosure through a sealed opening 14 and preferably opens at the bottom of the enclosure within the liquid 4.
  • the mixing chamber 13 is connected within the liquid 4, preferably at a location near the bottom of the enclosure, by a third tube 15 on which) is placed a diaphragm 16 forming a hole 16a, this tubing entering chamber 13 through a sealed opening 15a; thanks to the diaphragm, a pressure drop is created in this tubing.
  • the mixing chamber is arranged in such a way that the stream of compressed gas conveyed by the second tubing there encounters the stream of treatment liquid supplied by the third tubing thus generating the foam which is conveyed by a fourth tubing 17 to means of application thereof, for example a lance 18 comprising a tap 19.
  • the value of the diameter d of the hole formed by the diaphragm 16 is chosen as a function of the value of the pressure p applied downstream of the expansion means 6 so that, for a given liquid treatment product, the foam is formed by injection.
  • liquid product in the stream of compressed gas inside the mixing chamber constituted in particular by the space delimited by the pipes 10, 15 and 17 at their meeting point.
  • the mixing chamber 13 is formed by the meeting point of two tubes 20 and 21 arranged in "T" shape, as shown in FIG. 2.
  • the tube 20 which forms the bar of the "T” is connected to the pipes 10 and 17 ;
  • the tube 21 which forms the leg of the "T” is connected to the tube 15 by a nozzle 22;
  • the latter comprises at its end a flange 23 by which the diaphragm 16 which may be in the form of a washer, for example made of synthetic plastic material, is applied against the end of the tube 21.
  • the tightening of the washer 16 between the flange 23 and the end of the tube 21 can be carried out using a nut 24 cooperating with a thread 25 formed by the tube 21 and comprising a flange 25 which, when the nut is clamped on the tube, is applied against the flange 23.
  • the enclosure is filled for example three-quarters of the liquid treatment product prepared for example from a concentrate by dilution.
  • the cover 3 is then closed, the pipe 5 is adapted to the source of compressed gas 8 and the enclosure is placed under the desired pressure p by acting on the expansion device 6, the tap 19 of the lance 18 being closed.
  • the product in the form of foam can be sprayed onto the parts of the installation to be treated.
  • chambers with a capacity of approximately 100 liters making it possible to manufacture, for a charge, in particular of one or the other aforementioned product, a sufficient quantity of foam. to treat around 400 m- of surface.
