Definitions

  • the present invention relates to an agitator intended to homogenize a mixture of products, at least one of which is in the liquid phase.
  • the agitator is mainly intended to be used for resuspension and for maintaining the basic colors used in bodywork, with a view to achieving the colors corresponding to the various vehicles in circulation.
  • this agitator is rotated by a mechanical device, the axis of which passes through a cover securely fixed to the base shade box.
  • stirrers have a serious drawback when stirring base colors having significant decantations, for example in the case of metallized bases for which there is a deposit of several centimeters of concentrated aluminum powder. Indeed, none of these agitators has been shown to be sufficiently effective, the operator then having to carry out manual stirring before putting into service on the stirring machine.
  • the invention therefore aims to eliminate this drawback. It therefore proposes an agitator having an efficiency greater than that of the three types previously mentioned and which is suitable for environments with strong settling.
  • the agitator according to the invention comprises a helical blade rotatably mounted by means of a vertical axis pivoting at its upper part, in a bearing carried by the removable cover of said container, so as to create a mixing in the direction vertical and means making it possible to animate said blade with a vibratory movement of small vertical amplitude, this vibratory movement being generated from the rotational movement of the axis of the agitator.
  • the helical blade has at its base a scraping device constituted by a spring, or round wire, exerting constant pressure on the bottom and the side of the box containing the mixture to be stirred, this spring being able to or not participate in the development of the above vibratory movement.
  • the above scraping device is independent of the means ensuring the vibratory movement of the helical blade.
  • the scraping device can advantageously consist of a pin or the like coming to be mounted radially on the lower edge of the helical blade so as to be able to slide radially and pivot relative to the latter.
  • This pin further comprises an inclined portion intended to receive, during rotation, a hydrodynamic thrust F caused by the viscosity of the mixture to be homogenized, the radial component of which relative to the axis of rotation of the agitator F2 tends to slide. the pin so as to apply it against the side wall of the container causing a reaction R 1 and a scraping effect of the lateral deposit, and whose axial component 1 relative to said axis causes a moment of rotation M and a reaction R 2 on the bottom of the container ensuring the scraping of the bottom.
  • the agitator firstly comprises a vertical axis 1 pivotally mounted at its upper part in a bearing 2 formed integrally with a molded cover 3 of the type of those usually used by machines. body paint stirring.
  • a helical ramp 4 whose pitch has been determined experimentally in order to produce the most efficient stirring possible without the introduction of air during stirring.
  • the width of the strip of the ramp 4 is determined in such a way that there is sufficient volume around the axis 1 so that the paint which is quickly transported to the upper part can descend through the center and then repeat its movement indefinitely.
  • the helical ramp 4 is extended to the axis so that there is no unexplored area in the bottom of the box.
  • the invention has therefore provided a device making it possible to generate on the axis 1 and, consequently, on the ramp 4, vertical pulses of small amplitude and of determined frequency which manage to split the deposit and facilitate its sliding on the slide until it is dispersed in the solvent medium.
  • this device involves a tubular sleeve 7 which fits into the bearing 2 of the cover 3 and the lower edge of which forms a notched crown 8 having a sinusoidal shape.
  • This sleeve 7 can consist, for example, of a molded plastic part of a special composition resistant to wear and to solvents. It may also comprise a flexible circular lip 9 intended to provide a seal around the axis 1.
  • This assembly allows both to exert on the axis 1 the axial stress necessary to obtain the vibratory effect and to ensure scraping of the bottom 5 and the side wall of the box 6 over part of its height.
  • the helical blade of the agitator is fixed to a tubular sleeve 14 fitted at the end of the axis 1.
  • this sleeve engages the upper spiral part of the spring as well as, coaxially with this spring, the rod of a bearing stud 15 whose head 16, preferably rounded, is intended to come in stop against the bottom 5 of the box 6.
  • a quick coupling device to a motor member.
  • This device consists of a U-shaped fork 17 which cooperates with a rotary paddle of the drive member (not shown).
  • the axes of the agitator and the axis of the drive member are coaxial and the pallet is engaged between the two branches 18, 19 of the fork 17.
  • Such a coupling has the advantage of allowing a axial clearance of the agitator axis relative to the motor axis.
  • the bearing 20, in which the axis 1 is pivotally mounted projects on each side of the cover 3.
  • a tubular element 21 provided with a circular internal lip 22 intended to seal between the axis 1 and the cover 3.
  • a tubular sleeve 23 comprising, in its upper part , a bottom 24 provided with a coaxial bore 25 through which the axis 1 passes and, in its lower part, a collar 26. provided with holes 27 for fixing by screwing the sleeve 23 to the cover 3.
  • this agitator is substantially the same as that previously described. However, it should be noted that in this embodiment, the assembly producing the axial oscillations of the axis 1 is isolated from the products to be mixed thanks to the seal produced by the tubular element 21 and the lip 22.
  • the agitator first of all comprises a vertical axis 31 pivotally mounted at its upper part in a bearing 32 integrally formed with a molded cover 33. At the lower part of this axis 31 is fixed a helical ramp 34 of the type of that previously described.
  • a bushing 35 carrying in its upper part a drive pinion 36 and the lower part of which has a flared shape 37 in the shape of a bell in which the upper part 38 is introduced. of the bearing 32.
  • the lower edge 39 of this flared part forms a notched crown, for example of sinusoidal shape which comes to bear on at least one cleat 40 integral with the cover 33.
  • This notched crown 39 is held in contact with the cleat during the rotation of the axis 31 by means of a helical spring 41 arranged coaxially with the axis 31, c8-tee container 42, and which comes to bear, on the one hand at the lower part, on a self-locking metal ring 43 and secondly, at its upper part, on the cover 33 by means of a washer 44 made of non-stick plastic material such as, for example, polytetrafluoroethylene (PTFE) intended for seal between the outside of the container and the inside, with automatic wear adjustment thanks to spring 11.
  • This helical spring 41 is located inside a protective bellows 45 made of elastomer or plastic resistant to the various chemicals used in paints, and which is clamped on the axis 1 at the level of the washer 13.
  • the vibrator system (notching 39 / cleat 40) is located outside of the cover 33 in order to avoid the wear caused by certain paints whose pigments are abrasive.
  • the flared part 37 of the sleeve 35 may consist of a separate part, for example made of plastic, which carries in its lower part the above notching 39 (sinusoidal ramp).
  • the aforementioned cleats 40 which cause, by their action on the notch 39, the axial vibrations of the axis 31 can advantageously consist of two protuberances formed on a piece of stamped steel treated mounted on the cover 33 so as to be easily interchangeable in case of wear.
  • the scraper device consists of a pin 47 which slides very freely in two supports 48, 49 coming from molding with the base 50 of the helical ramp 34, or even possibly, produced by two clips coming to engage in two slots rectangular formed on said base.
  • this pin 47 comprises, at its upper part, an inclined part 51 which receives during rotation, a hydrodynamic thrust caused by the viscosity of the paint.
  • This strength can decompose into a force parallel to the axis of the supports 48, 49 so that the pin 47 is applied against the side wall of the container 42, causing a reaction R 1 and a scraping effect of the lateral deposit, and by a force perpendicular to one of the supports 48, 49 which causes a moment of rotation M and a reaction R 2 on the bottom 52 of the container 42, reaction whose value is more important than the force, given the relatively small distance.
