Definitions

  • FEEDER VALVES This invention relates to so-called feeder valves used for periodically discharging a quantity of material from a storage hopper.
  • the invention is concerned more especially, but not exclusively, with a feeder valve for use in the periodical discharge of a powdered or granular material from a storage hopper.
  • the known forms of feeder valves of the kind above described comprise a slidable plate for opening or closing the valve aperture.
  • Slide valves of this known kind have certain disadvantages and present certain prob lems.
  • the slidable plate can be subjected to considerable pressure from the material to be discharged from the storage hopper and therefore must be supported in such a manner as to reduce friction during at least the opening movement of the valve plate.
  • One known way of doing this is to support the valve plate on rollers but this complicates construction and therefore considerably increases cost of manufacture.
  • a still further disadvantage of the known form of slide valve is that during the opening movement of the valve plate the valve aperture is opened only progressively from one side to the other so that material is not discharged through the whole area of the valve aperture during the initial opening of the valve.
  • the object of the present invention is to provide an improved construction of feeder valve which does not suffer from the above stated disadvantages of the known construction of slide valve.
  • the feeder valve comprises a valve body having a valve aperture extending therethrough and a plurality of vanes or blades mounted across said valve aperture and rotatable about their axes from a substantially horizontal plane, in which they close the valve aperture, to a substantially vertical plane in which they open said valve aperture.
  • FIG. 1 is a cross-section through the feeder valve
  • FIG. 2 is a section on the line lI-ll of FIG. 1;
  • FIG. 3 is a side elevation of the feeder valve
  • FIG. 4 is a section on the line IVIV of FIG. 3;
  • FIG. 5 is a section on the line V V of FIG. 3.
  • the feeder valve comprises a valve body including an outer valve housing 6 provided at top and bottom with flanges 6a and 6b respectively for connection with a feed hopper or other equipment.
  • an inner casing 7 mounted within said outer valve housing 6 is an inner casing 7 having two of its opposite side walls spaced from the housing 6, as indicated in FIG. 1, and its two other opposite side walls in contact with the adjacent side walls of the outer housing 6.
  • the inner casing 7 may be made of any suitable material but is preferably made of nylon.
  • a vibrator frame Surrounding the outer valve housing 6 is a vibrator frame comprising end plates 8 and side plates 9, the end and side plates being connected at the comers of the vibrator frame by bolts 10.
  • the vibrator frame is spaced from and supported around the outer valve housing by means of laminated leaf springs 11, the vibrator frame being connected to the bottom flange 6b of the valve housing at one end and the top flange 6a at the other end by angle brackets 12 and bolts 13 respectively.
  • Rotatably mounted in bushes 20 or other suitable bearings in the side plates 9 are three spindles 14, 14a and 14b which extend transversely across the valve aperture in said inner casing 7 and pass freely through slots l5 in the side walls of the outer valve housing 6 and with a close fit in holes in said inner casing 7 whereby the inner casing 7 is vibrated by said vibrator frame 8, 9 whilst the outer housing 6 remains stationary.
  • a v'ane or blade 16 Fixedly mounted on each of said spindles 14, 14a and 14b within the inner valve casing 7 is a v'ane or blade 16, the construction and arrangement of which is such that they can be turned, by rotation of the spindles 14, into a substantially horizontal plane as indicated in dotted lines in FIG. 1, in which they close the valve aperture, or into a substantially vertical plane, as indicated in full lines in FIG. 1, in which they open the valve aperture.
  • the spindles of all of the vanes or blades are coupled together, whereby all of said vanes or blades can be rotated in unison.
  • one end of each of the spindles 14, 14a and 14b has fixedly mounted thereon a gear wheel 17 and between and meshing with each adjacent pair of said gear wheels 17 is a pinion l8 freely rotatable on a pin 19 fixed to the side plate 9 (FIG. 5).
  • the spindle 14b (FIG. 2) forms a drive shaft and is connected to suitable manual, mechanical, electrical or other drive means (not shown).
  • the means for rotating the spindles 14, 14a and 14b are such that the position of the blades 16 can be preset at any angle through to give the required feed from zero to maximum at which the feeder valve is rated.
  • the vibrator frame 8, 9 can be vibrated in any known manner, for example by means of a known form of pneumatic or electrically operated linear vibrator fixed on one of the end plates 8.
  • a shield or screen 21 is provided at the upper inlet end of the feeder valve.
  • gearing l7, 18 is arranged to cause the vanes or blades 16 to be rotated in the direction of the arrows in FIG. 1; said gearing may, however, be arranged so as to cause the vanes or blades on both spindles 14a and 14c to be turned downwards instead of one turning upwards and one downwards, as illustrated.
  • Other modifications can of course be made without departing from the scope of the invention.
  • the blades or vanes 16 may be of any suitable crosssectional shape but are preferably of such a shape that when in position to close the valve aperture provide a flat upper surface across said aperture.
  • a feeder valve for discharging fluent material from a storage hopper to a lower hopper comprising a valve body adapted to be fixed to said hoppers and defining a valve aperture, a vibrator, a plurality of spindles journaled in said vibrator and extending with clearance through openings in said body across said valve aperture, a vane carried by each of said spindles, means for rotating said spindles to move said vanes from a horizontal plane closing said apertures to vertical planes opening said aperture, and means resiliently connecting said vibrator to said body so that said spindles and vanes may be vibrated by said vibrator independently of said body.
  • a feeder valve according to claim 1 wherein said spindles are coupled together for rotation in unison by gearing comprising a gear wheel mounted on one end of each spindle and freely rotatable pinions disposed between and meshing with adjacent pairs of gear wheels and wherein one of said spindles is a drive shaft connected to suitable drive means.
  • valve body comprises an outer valve housing and an inner casing having two opposite side walls spaced from said outer housing and the two other opposite side walls in contact with adjacent side walls of said outer housing.
  • a feeder valve according to claim 3 wherein said vibrator comprises frame surrounding said outer housing in spaced relationship therewith said resilient means comprising spring means disposed one at each of two opposite ends of said housing, one of said spring means being connected between said vibrator frame and the top of said housing and the other spring means being connected between said vibrator frame and the bottom of said housing.
