Definitions

  • My invention relates to mixer apparatus, and
  • the oscillatory axis-- of the container is usually the same as the axis of" one 01' thesai'd mixer screws.
  • the container is adapted to be rotated through 90- about said axis in order to allowdischargingthe mixed products therefrom.
  • balancing means such as counterweights.
  • the container in order to be more readily oscillated, is provided with balancing means, such as counterweights.
  • the container has associated withit the drive means for the mixer screws, said drive means being generally arranged to one side of the container.
  • Another object is to'provide a mixing machine of that type in which the geometric and mechani cal relationships between the parts of the structure with respect to the centre of'g-ravity thereof are such as-to make it possible to dispense with the usual balancing means such as counterweights orthe like, while maintaining the desirable facility in the oscillational movements thereof;
  • a furtherobject is to provide such a mixing machine which maybe directly installed on asuitable foundation block without requiring a supporting frame: structure.
  • a related object is to provide an oscillating mixing machine in which the oscillating con-. tainer is adapted to be swung to a completely overturned position fordischarging purposes, thus facilitating evacuation of its contents.
  • Another object is to provide a mixer machine having the above-defined improved characteristics and in which the drive motor is mounted in a fixed position.
  • the container carrying the mixerscrews is mounted for oscillation on; a. central: axis independent from the screw shafts. and spaced therefrom, said. axis passing, substantial ly: through the centre. of. ravity of; the. cents" or when f-u-IL.
  • The. said container r g-i a pair of circular side flanges resting; on. till-Hr porting roller members.v
  • the mixerscrews aredriv on from a motor'notsunnorted. ozrthe. container but on one. of the sidefianees thereof and from which the movement; supplied through; a. Suit:- able, transmission comprising meshing gears: mounted at; the end. of the container, this are rangement. reducing the. overall dimensions of the; apparatus. It. is desirable to: provide said gears. in such a way that; they" willimpart tothe, screws reverseand idifierential rates; of rotation,. thus improving the conditions of the mixing opera;- tion.
  • the shafts of the; mixer screws are connected through meshing. gears mounted on one of the end flanges to a. o nnon. central shaft coaxial. with the, container and. driven through. asuitable. ansmis ion fr m. a fixed motor...
  • Fig.7 1 is .a view in longitudinal elevation of the mixer, with parts in section:
  • Fig. 2 is a side view-on line I'Ii-I'I of Fig. ,1;
  • Fig: 3 is a transversesection on line- III- 4131. of Fig. 1*.
  • the mixer essentially comprises a container I in which are disposed two oppositely-rotating revolving mixer means or mixer screws 2 and 3.
  • the container I is rigid with two fixed shafts 4 and 5, the common geometric axis of which is arranged substantially to pass through the centre of gravity G of the container when full.
  • Said shafts 4 and 5 are independent from the screw shafts 2 and 3 and serve as shafts for mounting the lay pinions referred to later.
  • Said shafts land 5 are respectively secured to the centres of two circular side flanged discs 6 and 'I.
  • the flanges 6 and I bear along the outer periphery thereof upon two pairs of rollers 8 and 9 preferably comprising ball bearings mounted on supports I! and II which directly rest on the concrete base I2. It will thus be seen that the mixer does not require any metal frame.
  • the rocking movement of the container is effected by rotation of the flanged discs 6 and I on the rollers 8 and 9, and said rocking movement may extend throughout an entire half-circle, so that the container assumes a vertical position reversed from its charging position, and the dis-. charge of the mixed products is facilitated.
  • the motor I8 which controls the movement of the screws is mounted.
  • the motor. shaft I8 carries a sheave l9 whose movement is transmitted through the belt to another similar sheave 2I driving the shaft 22.
  • Said shaft extends throughout the entire length of the mixer, passing through the flanges 6 and TI and being journalled in bearings 23, 24 carried thereon.
  • the container is perfectly balanced while it does not include any counterweight or similar means. It may be designed for large capacities without any difiiculty and without undue weight and bulk. It is especially easy and economical to make and to mount.
  • the gear trains at the end of the structure corresponding to flange I are enclosed in a housing 33 carried by this flange.
  • the drive mechanism for the shaft 22 comprises a gear 35 mounted on an extension of the shaft 22 beyond the pinions 25 and enclosed in a housing 34 secured 0n the housing 33.
  • the gear 35 is connected through an intermediate gear 36 to a pinion 31 secured on a shaft 33 mounted on the housing 34 in alignment with the shaft 5 and consequently in coaxial relationship with the oscillational axis of the mixer,
  • Said shaft 38 is connected through a suitable drive with a fixed drive motor 39 which may, as
  • said drive may comprise as shown a belt transmission to cooperating with a drive sheave 42 on the shaft of the fixed motor 39 and a driven sheave 4
  • the motor will at all times be capable of driving the screw shafts to produce the desired mixing effect; regardless of the position imparted to the container, and it is unnecessary that the motor be provided movable with the container as in thefirst-disclosed embodiment.
  • the shaft 38 may be directly coupled with a fixed motor disposed with its driveshaft in alignment with the shaft 38.
  • rollers 8 To produce therequisite oscillatory movements of the container, at fixed motor 43 is provided on aframe 44 supported on the floor and connected through a reducer gearing 45 to a shaft 43 having thereon a worm engaging a worm gear On a shaft 48 which is common to both rollers 8.; To improve the-"adherence characteristics thereof, said rollersare'formed with a -shaped ortrapezoidal groove in which the complementari-ly formed trapezoidal peripheral margins of the flanges are wedgingly'engaged.
  • the continuously-rotating motor 43 will be adapted to impart the desired oscillatory motion to the container, with the rollers 8 driving the flanges through friction.
  • the remaining two rollers 9 merely serve the function of bearing or supporting rollers as in the first-described embodiment.
  • a mixer comprising in combination a base, rollers supported on the base, a pair of spaced coaxial vertical flanged discs resting on said rollers, a horizontal container open at its top and rigidly disposed wholly between said discs; revolving mixer means mounted in the bottom ofsaid container parallel 'tosaid axis and journalled in said flanged discs, a longitudinal drive ing shaft'journalled in said fiangeddiscs, gearing;
  • a mixer according to claim 1 in which the shaft driving means comprise a motor fixed on one of said flanged discs and drive connecting means between said motor and said shaft.
