Definitions

  • the present invention concerns an agitator, particularly to an agitator assembly comprising of stirrers which can be replaced without emptying the liquid in the assembly.
  • agitator consists of a shaft fitted with stirring blades or paddles, mounted on a bearing in a base of a vessel wall, so that it can rotate.
  • a disadvantage of common agitators is that they can only be removed from a vessel when that vessel is empty and thus when the base is accessible.
  • GB915326 A teaches a batch mixing machine which has a shaft carrying a detachable stirrer comprising a hub and a ring with spokes having their leading edges above their trailing edges so that when the stirrer is rotated clockwise as seen from above, the spokes cause the mix to flow down- wards.
  • the trailing edges of the spokes are sharpened in order to prevent the mix from forming deposits thereon.
  • the ring also carries two pairs of vanes having their leading edges below their trailing edges to deflect the mix upwards.
  • the scraper vanes have sharp leading edges to scrape the base of the vessel and curved ends to co-operate with and scrape the curved portion joining the walls and the base ; the blades are straight and inclined upwardly towards the tip, their leading edges also being sharp.
  • the spokes and the vanes are twisted in opposite directions.
  • the stirrer shaft rotates in a hollow shaft which carries an arm from which depends an adjustable scraper blade .
  • the stirrer and the scraper blade are rotated in opposite directions and at different speeds by the motors.
  • the mixing implements can be raised clear of the container by means of the telescopic column ; the container is mounted on trunnions and can be emptied by tilting.
  • the mixer is intended primarily for the mixing of certain dry powder or graular thermoplastic substances of which one may become sticky due to the heat generated by the mixing.
  • this setup does not permit changing or removing the stirrers when the machine is with the material to be mixed.
  • US2012516 A teaches a motor driven beater comprising a motor, a gear casing rigidly connected to the motor, a motor shaft extending into said gear casing, a pair of rotatable shafts journalled in the gear casing and operatively connected to the motor shaft, and a quickly detachable agitator unit, including a pair of agitator rods having beater elements thereon, the upper end of each agitator rod extending into the gear casing into axial alignment and operative engagement with one of said rotatable shafts, said agitator rods being quickly removable from operative engagement with the shafts, in the gear casing by moving the agitator rods axially in a direction away from the gear casing.
  • the gear assembly results in a complicated machinery to remove and deal with.
  • the present invention aims at providing a solution to the aforementioned and other disadvantages.
  • the present invention concerns an agitator that mainly consists of a shaft fitted with stirring blades or paddles, mounted on a bearing in a base, so that it can rotate axially and be detached.
  • the base is fixed to an end of an arm that is fitted with links on its other end that allow fixing the arm in a vessel or the like in such a way that it can rotate.
  • An advantage of the present invention is that the shaft and the base of the agitator can, at least partially and by preference entirely, be removed from the vessel by rotating the agitator, so that the shaft can be removed from the base and can be replaced by another shaft, for example.
  • the present invention allows removing the functional part of the agitator, i.e. the shaft with the stirring blades or paddles, from a vessel and replacing it without having to empty the vessel.
  • the arm's length preferably equals or exceeds the distance between the point where the arm is fixed to the vessel and the maximum liquid level B in the vessel, so that the base of the shaft can be moved above liquid level B in case the vessel is filled.
  • Figure 1 shows a vessel in which an agitator is fitted according to the invention
  • Figure 2 shows another embodiment of the present invention.
  • FIG. 1 shows a vessel 1 in which an agitator 2 is fitted according to the invention.
  • the agitator 2 mainly consists of a shaft 3 which is mounted in a base 4 so that it can rotate axially and be detached.
  • a drive 6 is fitted on the free end of the shaft 3 that allows the axial rotation of the shaft 3.
  • the aforementioned base 4 is fitted to an arm's end 7 so that it can rotate, while the free end of this arm is fixed to links 8 that allow fixing the arm 7 to a wall so that it can rotate.
  • the wall is a bottom wall 9 of the vessel 1.
  • the length A of the arm 7 preferably exceeds or equals the maximum liquid level B in the vessel 1.
  • the vessel 1 contains a side wall 10 in which an opening 11 is provided, through which the free end of the shaft 3 of the agitator 2 extends.
  • the length of the aforementioned arm 7 equals the distance of the aforementioned links 8 in the vessel up to the opening 11 in the side wall 10.
  • the bottom wall 9 of the vessel 1 is provided with a device, in the shape of a clip or the like, which allows fixing the base 4 to the vessel 1 in such a way that it can be detached.
  • the base 4 can be removed from the clip by pulling the free end of the shaft.
  • the base 4 In a position, as shown by the continuous lines in figure 1, the base 4 is located on the bottom wall 9 of the vessel 1 and the stirring blades or paddles are located below the maximum liquid level B in the vessel 1.
  • the agitator 2 can be driven in order to stir or mix a liquid in the vessel 1.
  • the free end of the shaft 3 should be further pulled out of the vessel 1.
  • the base 4 is then lifted from the bottom wall 9 of the vessel and the arm 7 rotates around the links 8 until the link of the shaft 3 and the base 4 is easily accessible through the opening 11.
  • the shaft 3 can be removed from the base 4 and possibly be replaced by another shaft 3 with other stirring blades or paddles 5.
  • the arm 7 rotates down into the vessel 1 until the base 4 rests again against the bottom wall 9 at the same location as before removing the agitator 2 from the vessel 1.
  • the agitator 2 can also be driven in an intermediary position, in order to stir or mix a liquid in the vessel 1.
  • Figure 2 shows an embodiment, in which the arm 7 is fixed to a side 10 of the vessel 1 in such a way that it can rotate, while the aforementioned opening 11 is fitted in an upper wall 12 of this vessel 1.
  • agitator 2 is analogous to the operation described above.
  • the base 4 can also be fixed to various arms 7 that extend obliquely one from the other, and each of which are provided with links 8 that allow fixing the arms 7 in the vessel 1 in such a way that they can rotate.
  • arm or arms 7 can be composed of various arm parts that can rotate mutually, in order to increase the scope of the shaft 3 while moving the agitator 2 in or out of the vessel 1.

Abstract

La présente invention concerne un agitateur qui est essentiellement constitué d'un arbre (3) équipé d'aubes (5) ou palettes agitatrices, monté sur des paliers dans une base (4), de sorte qu'il puisse tourner de façon axiale et soit détaché. Elle est caractérisée par le fait que la base (4) est fixée à une extrémité d'un bras (7) qui est pourvu de liens (8) sur son autre extrémité qui permettent la fixation du bras (7) dans un récipient (1) ou analogue afin qu'il puisse tourner.
