Definitions
- the present invention relates to an autonomous device for generating viscose foam.
- viscose foams that is to say enriched with a gelling agent which increases the physical stability of the foams and makes them less able to flow on even very inclined or vertical surfaces.
- a gelling agent which increases the physical stability of the foams and makes them less able to flow on even very inclined or vertical surfaces.
- WO 2013/067401 A2 An example of a foam generating device is described in WO 2013/067401 A2; this device is partially portable, but it is designed for ordinary foams used against fires.
- An object of the invention is to manufacture foams, in particular special high-expansion foams, reliably, at a high rate, by means of a suitable generator whose operation is stable.
- the invention relates to a device for generating foam, comprising a reservoir of a foaming liquid, a cylinder of compressed gas, a first pipe leaving the reservoir and passing through a pneumatic pump while being connected to suction and discharge ports of said pneumatic pump, a second conduit exiting from the bottle and passing through a regulator, the first conduit and the second conduit joining at a junction; a conduit for transporting a mixture of the foaming liquid and the compressed gas extending between the junction and an end (7) for ejecting the foam; a mixer of the foaming liquid and the compressed gas, at an inlet of which the first conduit and the second conduit end and in which the foam is formed, and located on the conduit for transporting the mixture between the junction and the ejection end; the second conduit comprising a bifurcation leading to a starting port of the pneumatic pump; characterized in that the mixer comprises a cylindrical wall open at the two axial ends and through which the mixture passes between the said axial ends, a cage formed in the cylindrical wall, and at
- This device where the compressed gas is used both to make the foam and to suck the foaming liquid out of its reservoir, makes it possible to dispense with the need for an electrical power supply to the device involving either the servitude of an external supply by cables, or a heavy battery.
- the flow rate of the liquid drawn in, conditioned by the energy supplied to the pump is proportional to the pressure of the compressed gas, and the flow rate of the compressed gas used to produce the foam is also proportional to this pressure.
- the stability of the expansion of the foam that is to say of the value of its liquid fraction, is therefore guaranteed without any adjustment.
- the mixer integrated into the device is well suited to produce a foam having the required qualities. Since the balls are few in number in the cage and of much smaller dimensions than the latter, they do not form superimposed layers there but on the contrary remain free and perform independent and significant movements, capable of giving a high expansion of the foam.
- the device comprises a manometer for measuring the pressure of the compressed gas in the bottle;
- the mixture transport conduit comprises a flexible lance
- the device comprises a single control lever, arranged on the lance, for opening the lance and ejecting the foam;
- the cage is delimited by two successive grids in the cylindrical wall; - the device is mounted on a portable frame or a rolling cart, and completely independent, in service, of external supplies, in particular electricity or fluids.
- FIG. 1 is a diagram of an embodiment of the invention
- FIG. 2 shows the mixer
- the device comprises a tank 1 of foaming solution in the liquid state, a bottle 2 of compressed air, a pressure gauge 3, a main regulator 4, a pneumatic pump 5, a mixer 6, a foam ejection end 7, and a frame 8.
- a first conduit 11 connects an outlet orifice of reservoir 1 to a suction orifice 12 of pneumatic pump 5; it emerges from the pneumatic pump 5 through its discharge orifice 13, passes through the mixer 6 and ends at the end 7.
- a second conduit 14 connects an outlet orifice of the bottle 2 to the main regulator 4, then joins the first conduit 11 at a junction 15 made between the discharge orifice of the pneumatic pump 5 and the mixer 6.
- a bifurcation 16 of the second conduit 14 leads to an orifice 17 for setting the rotor of the pneumatic pump 5 in motion (possibly via a second pressure reducer 43 to independently adjust the pressure there).
- the bifurcation 16 leaves the second conduit 14 just downstream of the main regulator 4 and therefore transports slightly compressed air at constant pressure (7 bars for example).
- the pressure gauge 3 is connected by a pressure tapping conduit 20 to the second conduit 14, upstream of the main regulator 4, and it therefore makes it possible to measure the pressure of the gas at the outlet of the bottle 2 and to evaluate the filling of that -this.
- the frame 8 carries the tank 1, the bottle 2, the main regulator 4, the pneumatic pump 5, the first pipe 11 and the second pipe 14.
- the frame 8 can be vertical and belong to a bag backpack carried by the operator of the device; the frame 8 can also be a trolley, for example.
- the foam ejection end 7 is not attached to the frame 8, but is located at the end of a flexible lance 21, held by the operator.
- the lance 21 extends between the end 7 on the one hand, and the junction 15 on the other hand.
- the mixer 6 is located on the path of the mixture of liquid and compressed air between the junction 15 and the end 7, and it is represented in FIG. a cylindrical wall and occupying its entire section, two seals 29 to which the grids 28 are respectively fixed and which serve as their support for the wall of the bore 24, and spherical and rigid balls 30 free to move between the grids 28.
- the seals 29 serve to hold the grids 28 in place and to form between them a cage 31, further delimited by the wall of the bore 24, and in which the balls 30 are retained. They also force all the fluids circulating in the bore 24 to pass through the inside of the cage 31.
- This type of mixer comprising balls, or more generally solid bodies, free in a cage through which the previously mixed fluids pass has proven to be very effective in producing foams whose expansion is well determined and possibly high, i.e. ie low liquid fraction. It is particularly suitable for the manufacture of viscose foams.
- the cage 31 can be 10 to 400 mm in length, 10 to 100 mm in diameter, and the balls 30 from 2 to 20 mm in diameter. Free and independent movements, of great amplitude, of the balls 30 being sought to give a high expansion, a very low filling of the cage 31 by the balls 30 is sought.
- the balls 30 do not form superimposed layers at rest.
- They are 1 to 40 in number, with a diameter 2 to 10 times smaller than the diameter (or the dimensions transverse to the X-X axis) of the cage 31; more advantageously, from 4 to 8 times smaller than this diameter; and at best, about 5 times lower.
- Figure 3 shows that the end 7 is attached to the front end of a barrel of a gun 32 held by the operator, the rear end of which is joined to the lance 21. The operator opens the lance 21 and triggers the projection of foam by pressing a trigger 35 of the gun 32.
- Figure 4 illustrates a possible arrangement of the equipment on the frame 8, where there is still shown a spare tank used when the first (tank 1) has been emptied.
- the device is devoid of any servitude, that is to say any supply from the outside, the operator can put it on or transport it without constraint in remote or inaccessible places. He seizes the lance 21 by the gun 32 and presses the trigger 35 when he is in front of the surface to be covered with foam.
- the opening of the lance 21 allows the compressed air to flow through the second conduit 14. Part of the flow passes through the pneumatic pump 5, starts it up and serves to suck in an invariable flow, proportional to the flow of air passing through the pump 5, of the foaming solution out of the tank 1.
- the pumped foaming solution and the main flow of compressed air, which is directed to the lance 21, come together at the junction 15, upstream of the mixer 6.
- the flow rate of the foaming solution and that of the compressed air which mixes with it are proportional and therefore have an invariable ratio, determined by the physical characteristics of the fluids and of the device.
- the foam is formed by the mixing of the air and the foaming solution, passing through the mixer 6, which is very effective in obtaining a high expansion foam, sought among other things for viscose foams.
- Bottle 2 capacity of 31, starting pressure of 300 bar;
- Main regulator 4 reduces the pressure to 7 bar
- Second regulator 43 reduces the pressure to 4 bars
- Rigid balls 30 from 1 to 40, from 2 to 20 mm in diameter;
- Foaming solution water, with Glucopon 215UP [BASF] at 10g/l, and Xanthan Gum (G1253) [Sigma Aldrich] at 3g/l;
- the foam holding time is at least 120 min.
- the balls 30 could be replaced by another freely movable solid body in the cage 31, and their number could also be different, a single solid body being possible.
