Definitions

  • the present invention relates to the mixing of viscous and / or fluid product. It concerns first place a device for mixing viscous products and / or fluids comprising a sealed container provided with at least one outlet. Said container is intended to receive products to be mixed and contains an agitator for mixing said products.
  • Patent FR-A-1 208 222 describes a device comprising a cylindrical container in the axis of which is mounted agitator shaft, radially provided with wires or patch bars, etc.
  • the agitator's training is done by any motor, for example electric or compressed air.
  • the first mixing chamber leads to a product supply duct, as well as an air duct compressed.
  • a passage connects the mixing chamber to the expansion chamber.
  • the expansion chamber is in turn connected by means of an expansion valve and a diaphragm elongated, for example a narrow tube, to the mixing, where normal pressure prevails.
  • a mixing chamber is also fitted with an agitator, which is integral with that which is mounted in the cylinder of mixing.
  • an extension for example a pipe that can fill the function of an elongated nozzle, lead several conduits such as an agent introduction conduit hardening, comprising a metering and setting.
  • the device produced according to patent FR-A-1 208 222 uses dynamic seals between the agitator shaft and the container which limits the operating pressure at 100 bars.
  • the pressure generates a friction force important seal on the shaft and it follows heating sometimes harmful to the products. This generates also higher engine power.
  • the seal As the products are not necessarily lubricating, the seal has a limited life. It always happens leaks at the joint, which can be unacceptable with dangerous products, or gases.
  • the present invention overcomes these drawbacks and brings various advantages consisting essentially of this the product flows in the same direction, either systematically scanned and crosses the entire device without pressure drop variation whatever the position of the agitator stopped or in operation.
  • the invention relates to a device according to claim 1.
  • the invention also relates to an installation for manufacturing parts made of foamed material of the type comprising a tray in contact with a sealed barrel provided with minus one compressed gas supply pipe, one purge and an outlet pipe fitted with at least one pump, said outlet conduit being connected to a device mixer feeding an extrusion nozzle, the device being as defined above.
  • the invention also relates to the use of a device corresponding to the device described above to mix, under pressures ranging up to 300 bar, products to form parts out of material foamed such as static seals deposited in situ or by transfer.
  • the installation shown in FIG. 1 has a drum 1 forming a reserve of viscous thermoplastic product 2 and a lifting table 3.
  • the barrel is closed by a heating plate 4.
  • the lifting table is in contact with product 2 and the heating plate 4 by means of a hydraulic cylinder 5.
  • a double-acting pump 6 actuated by a jack hydraulic 7 with double rod 8 is mounted on the plate 4.
  • the heating plate 4 is connected by a pipe 9 to a mixing device 10 comprising a container waterproof 11 provided with a product supply duct 12a viscous 2, a nitrogen inlet pipe 12b 13 and a outlet 14.
  • the container 11 contains a agitator 15.
  • a flexible tube 16 disposed substantially parallel to the bottom of the agitator is connected to the outlet 14.
  • the flexible tube 16 is connected to a gun 17 by a duct 18.
  • the gun 17 has a nozzle extrusion 19.
  • Nitrogen 13 is contained in a bottle 20 connected to a compressor 21, itself connected to the supply duct 12b.
  • the operation of the installation is as follows: the barrel 1 is placed and centered on the lifting table 3 which keeps product 2 and tray 4 in contact with a constant force thanks to cylinder 7. Via line 9 and the supply duct 12a, the product is directly admitted into the mixing device 10.
  • Nitrogen 13 from bottle 20 is admitted in the hydropneumatic compressor 21 which raises the pressure at 300 bars. Nitrogen under pressure is introduced in the mixer device 10 via the supply duct 12b. By a movement of the agitator 15 in the container 11, the product 2 and nitrogen 13 are mixed. Under the effect of temperature and pressure, product 2 containing the dissolved nitrogen is conveyed through line 18 to pistol 17 which extrudes it to form a seal crosslinking with humidity on the part where it adheres.
  • the mixing device 10 can be used in the installation described above and shown in Fig. 2 comprises a container 11 provided with a supply conduit (12) comprising a part rigid upper 22 and flexible lower part 23 linked by a fixing ring 24 to an eccentric 26 by through a support 27 having a protuberance cylindrical 28 housed eccentrically and slightly inclined with respect to the axis of the eccentric.
  • the eccentric is mounted free to rotate in a chassis 29.
  • a motor 30 placed under the chassis 29 is connected at eccentric 26.
  • the support 27 has a pipe 31 coming from from the bottom of the container 11 and opening into the flexible tube 16.
  • the rigid part 22 of the container is consisting of two superimposed parts 32, 33 closed by a cover 34.
  • the internal part 35 of the part 33 has partly a frustoconical shape flared towards the cover 34.
  • the agitator 15 comprises a part cylindrical 36 fixed to an operating arm 37.
  • the part cylindrical 36 is housed in the internal part of the part 33.
  • the operating arm 37 is partially housed in the flexible part of the container 11.
  • a washer elastic 38 presenting days is interposed in the internal part of the rigid part of the container 11 at level of the junction between the operating arm 37 and the part 36.
  • the arm of maneuver 37 is linked to the support 27 by means of a ball joint 40 housed in a hollow cylindrical part 41.
  • the ball 40 has through holes 42 open in the room hollow 41.
