Definitions

  • the invention relates to the technical sector of devices used for mixing various materials arranged in bulk in a closed enclosure and which, using tools, scrapers and the like, allow the mixing of the different inserted products.
  • mixers for treating powdered materials, or in other applications, and which essentially comprise a closed enclosure receiving an upper opening for introducing the products and a lower emptying valve after mixing them.
  • mixers generally have a very long, cylindrical configuration, and receive, through their transverse ends by means of connection and rolling bearings, a very long axis passing through the mixer.
  • This axis is coupled with a known drive member of any suitable type, said axis receiving along its length support arms of tools of the plowshares type, scrapers, allowing the mixing of the materials collected and a homogenization of all the products contained. .
  • the low efficiency of the tools used to date is such as to reduce the quality of the work performed or therefore requires extremely long brewing times, which in some cases have been measured for capacities given at around 240 seconds.
  • the aim sought after according to the invention was therefore to remedy these drawbacks by proposing a new solution in the production of the tools associated with the mixer rotor, making it possible to obtain greater mixing efficiency, better recovery of the materials treated with inside the mixer to homogenize the diffusion and distribution of the different material compositions.
  • Another object sought after according to the invention was to produce tools which can be used both in mixers operating continuously, only discontinuously.
  • Continuous operation corresponds to an uninterrupted mixing of the materials composing the mixture which enter simultaneously at one end of the mixer at a given flow rate, progress in a continuous flow inside the tank and come out after homogenization at the other end, according to the same flow.
  • the batch operation is carried out charge by charge and comprises three successive phases: filling the tank, mixing, emptying the tank.
  • the mixer is of the type comprising a very long casing forming an interior chamber for the collection of different types of products to be mixed, having a filling opening and a product drain opening, and including a rotating shaft associated with a motor, said shaft being arranged along its length to receive stirring tools characterized in that said stirring tools fixed to each arm, are constituted by a blade having a profile combining a helical shape in its length according to a given angular sector, and a flared transverse shape allowing a lifting and gathering of the products to be brewed in the mixer.
  • the blades with a double helical and flared profile are metallic and receive an anti-corrosion treatment.
  • the blades with double helical and flared profile are arranged on the motor shaft in a particular configuration and in different angular orientations to allow complete and continuous mixing of the mass of materials inside the mixer.
  • the mixer is referenced as a whole by (1) and is of any known type, of any length and dimensions appropriate as required, and according to the mixing applications of the products.
  • These products can be powdered, granular or other.
  • the mixer is hollow internally with advantageously a cylindrical shape (1.1). It receives at its transverse ends bearings (2) allowing the support and the rolling guide of a shaft (3) of great length, said shaft being coupled to a drive member (4) arranged outside the mixer, being supported in any suitable manner.
  • the shaft (3) is arranged along its length with a plurality of supports (5) attached and welded or fixed in any suitable manner on the shaft.
  • these supports (5) are arranged to receive and allow the coupling of long radial arms (6), substantially less than a radius of the cylindrical mixer, and having tools at the end stirring (7) in the form of blades having a double helical and flared profile.
  • This particular double helical profile in its sense longitudinal and flared in its transverse plane, allows the blade to overturn in contact with the mixer tank.
  • the angulation given of the helical movement is established on variable angles from 30 to 45 ° and the vertical movement given by the reversal of the blade is accompanied by a suction effect given by the speed of rotation of the shaft. thus causing a takeoff of the products in contact with the tank, and restoring these products in an overall vortex movement.
  • the tools in the form of blades are thus arranged as close as possible to the inner wall of the tank.
  • the blades thus produced are established on appropriate lengths in correlation with the dimensions of the mixer and the applications of the products to be mixed.
  • the blades are metallic and receive an abrasion-resistant coating, and more particularly, it is arranged to the scraper end of the blade, an additional buffer layer (8) having an anti-abrasion effect.
  • the blades are fixed by welding in the middle part to their support arms, said arms possibly being able to receive a complementary transverse stirring fin (11).
  • the arms are fixed by bolting (9) to the support arranged on the shaft.
  • Elongated slots (10) can be provided at the connection zone of the arms on their supports, allowing adjustment in depth position of the stirring blades relative to the internal tank of the mixer.
  • the supports have a U-shaped profile (5.1) allowing self-centering of the arm fixing ends.
  • Some successive blades may partially overlap to have an effect of mixing the mass of materials collected in the mixer.
  • Some of the blades can be mounted on the right or left relative to the arms, giving a different inclination in opposition and thus allowing a combination of movements and swirling of the materials.
  • the anti-corrosion coatings of the blades are of any suitable nature.
  • the angular variation of the propeller pitch is established according to needs and applications.
