Definitions

  • the present invention relates to a mixing device in liquid and / or powdery products.
  • the outer tube 10 having a open end 12 for mixing outlet and one open end 14 for the introduction into compounds of one of the products to be mixed.
  • the system for introducing the second product to mix.
  • Inside the tube 10 there is a rotary mixing member 18 which has the shape of a helix extending over a large part of the length of the tube.
  • the mixing member 18 is rotated around of the axis x, x 'of the tube by a motor 20.
  • the rotation of the propeller 18 ensures that both the mixture of liquid and / or powdery products as well as driving the mixture produced towards the outlet end 12.
  • Document US-A-3.381.801 describes a tubular device of powdery products.
  • This device includes a drive propeller and an axial rod mounted inside the propeller.
  • One end of the rod is integral with the tubular casing of the device and this rod extends over the entire length of the product path pulverulent in order to limit the free volume for the pulverulent product.
  • a such a device can in no way solve the problem posed.
  • An object of the present invention is to provide a device for mixture of liquid products and / or powdery products which allow to avoid the risk of rocking the mixture on the mixer propeller without reducing the efficiency of the mixer, nor reducing its flow.
  • the mixing device continuous liquid and / or powdery products including at least one external tube, means for supplying products to mix, arranged at one end of the tube, the second end of the tube being open for the outlet of the mixture, a mixture in the form of a helix with internal diameter D arranged at inside the tube, and means for rotating the member mixture around the axis of said tube, further comprises an elongated part and closed at its two ends, of diameter d, with d ⁇ D, and of length I less than the length L of the mixing member, said piece being mounted free radially inside the mixer member and being free radially with respect to said external tube to form an unbalance, and means for axially holding said cylindrical part inside of said mixing member.
  • the elongated cylindrical part which is mounted free inside the whorl forming a mixing member constitutes the equivalent of an unbalance. Due to the rotation of the propeller and the absence mechanical connection, the cylindrical part hits the internal face of the turns of the propeller preventing the armouring of the mixture or causing its detachment of the propeller. In addition, it is understood that the cylindrical part is immobilized in translation on the one hand, by the holding means arranged at the outlet end of the mixer and on the other hand, by the effect products to mix driven by the mixing member.
  • the elongated piece freely mounted in the mixing element will have different dimensions and suitable weights.
  • the ends of the elongated part are profiled.
  • the mixer includes, in addition to the elements already described in connection with the Figure 1, an elongated piece 22, preferably of substantially shaped cylindrical which is freely mounted inside the mixing member 18 in propeller shape. In particular, it can move freely inside of the propeller in the radial directions thereof.
  • the elongated part 12 is closed at its two ends 22a and 22b. It has a length I and a diameter d.
  • a axial holding device for the elongated part 22 near the outlet end 12 of the mixer and at the end 18a of the mixing propeller 18, there is provided a axial holding device for the elongated part 22.
  • This device 24 can be a perforated plate placed across the tubular pipe 10 in such a way that it lets the mixture pass but retains the part elongated 22 by its end 22b.
  • the part 22 is mounted free radially inside the propeller 18, this part will behave as an imbalance inside the propeller 18.
  • the part 22 is kept inside the propeller 18 beyond the zone 16 for introducing one of the products to be mixed.
  • the part 22 undergoes a force F which tends to move it towards the outlet end 12 of the tube and, so antagonist, the part 22 is retained by the holding member 24.
  • the part 22 is completely free inside the propeller 18 according to the radial directions of it and it is only held by the organ holding 24 in the longitudinal direction without however being mechanically linked to this organ.
  • the length I of the part 22 is such that the part 22 is entirely disposed between the introduction zone 16 of one of the products to be mixed and the end of the turn 18.
  • Its diameter d is, of course, dependent on the diameter internal D of the propeller 18 and also dependent on the nature of the products to be mixed. In the case of products liable to form lumps, a small value d will be chosen so that the part 22 behaving like an unbalance, beats the propeller and the material to be mixed as much as possible and grinds the lumps in the mixer.
  • the diameter d also depends on the viscosity of the products to be mixed. The higher the viscosity, the smaller the diameter d to avoid blockage of the mixer.
  • the clearance between the internal face of the propeller when the latter has a diameter of 100 mm and the part 22 will be between 5 mm and 20 mm at the radius. In other words, the total play is between 10 mm and 40 mm. More generally, this clearance is between 10 and 50% of the internal diameter D of the propeller 18, that is to say that the diameter d of the part 22 is between 90% of D and 50% of D.
  • the weight of the piece 22 must also be adapted to the nature materials to mix. Generally, room 22 will be made in such a way that it is as light as possible. Through example, for a propeller with an internal diameter of 100 mm, its weight will vary from 500 g to 1,500 g. The more viscous the product, the more the weight will be important to keep the phenomenon of unbalance. However, the less the product will be viscous and the lighter the part 22 to avoid the introduction of vibration phenomena.
  • the ends 22a and 22b of the part 22 are shaped to promote the flow of the mixture. They can have the shaped like a cone or warhead.
  • the part 22 is advantageously made with a material flexible and light such as plastic materials and / or materials composites in order to avoid excessive shocks between part 22 and the mixing propeller 18 and to prevent the creation of vibrations in the whole device.
  • the part 22 preferably has a cross section substantially circular.
  • this cross section could be a polygon for that the part 22 has edges capable, in certain cases, of favor action on riprap.
  • Exhibit 22 can also be equipped with a propeller on its external face whose pitch is opposite to that of the mixing propeller 18. This arrangement favors the mixing of products to be mixed.
  • the mixer includes a second tube 30 in diameter lower than the tube 10. Its end 30a stops at the level of the device 16 of introduction of the second product to be mixed. Its second end 30b is enlarged and is provided with a hopper 32 for introducing the first product.
  • a second propeller 34 for driving the first product extends over the entire length of the second tube 30. The second propeller is rotated by a second motor 36. Between the end 30a of the second tube and the open end 12 of the first tube 10, we therefore finds the mixing chamber 38.
  • the cylindrical elongated part 22 which is identical to that of the Figure 2 shows a length I which is less than the length of the mixing chamber 38.
  • This second embodiment presents all the advantages of the first embodiment of FIG. 2.
