Definitions

  • a centrifugal drier of the top-loading, bottom-unloading type, as used for metal parts, has a conical stocking or loading hopper fixed above the top of a rotary basket.
  • a sliding drawer, actuated by a jack, with a semi-circular cut-out at the front facilitates even distribution of the load into the basket.
  • the bottom of the basket can be opened and closed by a jack arranged in the shaft suspending the basket. Pulsed hot air can be directed into the basket.
  • the present invention relates to centrifugal driers for metallic or other parts of small dimensions which must be centrifuged and dried, especially after various surface or thermal treatments to which the latter are subjected.
  • This centrifugal drier of the type loading through the top and unloading through the bottom is characterized in that it comprises a hopper for stocking or loading, of conical shape, fixed at the upper part of the drier and closed at its lower part by a drawer of suitable form enabling, on one hand, a regular distribution of the load to be dried in the basket of the drier, and on the other hand, the preparation of a second load while the first is in the course of treatment in the aforesaid basket, said basket having a bottom which may be retracted at the end of the centrifuging operation for removal of the treated load.
  • the means for opening and closing the bottom of the aforesaid basket is constituted by a jack, simple or double acting, hydraulic or pneumatic, advantageously incorporated in the suspension device of the basket thus reducing the mass.
  • the opening and closing of the loading drawer are also obtained by a jack, hydraulic or pneumatic, simple or double acting.
  • FIG. 1 is a vertical axial section view of a centrifugal drier according to the invention, taken along the line 11 of FIG. 2;
  • FIG. 2 is a plan view from above of this same loading device.
  • the drier is composed of a basket 2 receiving the parts 3 to be dried by centrifuging.
  • the basket '2 is fed from a hopper 4 for stocking the load 5 to be dried, capable if necessary of being raised as illustrated in chain-dotted lines in FIG. 1.
  • the hopper 4 is closed at its base by a drawer 6 capable of being displaced horizontally by a jack 7, simple or double acting, hydraulic or pneumatic, as desired.
  • the drawer 6 comprises, at its front part, a cut-out part 8 in the form of a semi-circle, which, upon opening the latter under the action of the jack 7, provides progressive exposure as illustrated in FIG. 2, of the loading opening in a manner to ensure a more regular distribution of the load 5 to be dried in the basket 2 thus avoiding the imbalances always troublesome in machines rotating at great speed.
  • the basket 2 is provided with a conical bottom capable of being brought into the position illustrated in chaindotted lines in FIG. 1, so as to release the load contained in the basket 2.
  • the means for the retraction of the bottom 9 is constituted especially, according to one preferred form of the invention, by a jack 10, advantageously incorporated in a suspension block 12 of the drier, the jack 10 having a piston 13 rigidly fixed to a shaft 14.
  • the shaft 14 is provided with ball-bearings 15 intended to avoid its rotation during the operation of the apparatus and it axially drives the bottom 9 through a box 16 capable of being displaced axially in a tubular shaft 17 supporting the basket 2, the said box being traversed by an axle 18 penetrating at two diametrically opposite locations in the walls of a cylindrical sleeve 9a extending upwardly from the bottom 9.
  • This axle 18 is capable of being displaced vertically in two slots 19 and 20 cut in the tubular shaft 17.
  • the load 5 to be treated is brought in any suitable manner, such as by conveyor belt, or by carriage, or the like and arranged in the stocking hopper 4.
  • the drawer 6 is then actuated by operation of the jack 7 and the load is distributed regularly in the basket 2.
  • the drawer is then closed again and the drier placed in operation.
  • a new load is introduced and stocked in the hopper 4.
  • the rotation of the basket is stopped, and the jack 10 is actuated, thus displacing the bottom 9 in the direction of the arrow 22 of FIG. 1, to bring it into the position illustrated in chain-dotted lines.
  • the dried parts then travel, along the direction of arrows 23 of FIG. 1, into a receptacle, not shown in the drawing, which directs them externally of the machine where they are received by a conveyor belt or carriage, or the like.
  • the bottom 9 is then raised again to contact the basket 2 and a new load is admitted into the latter after opening the drawer 6; the latter is then closed again and a new load is placed in the hopper 4.
  • the loading and unloading operations of the basket 2 are practically instantaneous and thus eliminate loss of time due to handling of the parts.
  • the various operations may be manually or automatically controlled.
  • a programmed automatic cycle which effects the various operations, the parts being evacuated after treatment by an other conveyor belt.
  • a centrifugal drier of the type having a rotary basket with suspension means and means for loading through the top and unloading through the bottom, used especially for the draining and drying of metallic or other parts
  • said drier comprises a loading hopper of conical shape fixed at the upper part of the drier, sliding closure means at the bottom of the hopper enabling regular distribution in the basket of a load to be dried and preparation of a further 3 load while-one load is being treated in the basket, and retracting means for opening and closing the bottom of the basket to enable emptying of the treated load at the end of the drying operation.
  • a centrifugal drier according to claim 1 including an inlet tube arranged to direct pulsed hot air into the basket.
