Application filed August 18, 1908. Serial No. 449,026.

To all whom it may concern:

Be it known that I, JOHN H. DUNCAN, of Ithaca, in the county of Tompkins and State of New York, have invented a certain new and useful Drying Apparatus, of which the following is a specificat on.

M invention has for its object the productlon of a simple and efiicicnt apparatus for dr ing precipitates, articularly applicable or drying salt; an it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in. all the views.

Figure l is an elevation of my apparatus, the sup orts for the vacuum pan, drying receptac e, and other parts being omitted.

Fig. 2 is a vertical sectional view of the drying receptacle.

As illustrated, this apparatus for drying precipitates comprises a vacuum pan, and a drying receptac e for the precipitate, the drying receptacle being connected to the vacuum pan so that the saturated-liquor is drawn from precipitate in the drying receptacle into the vacuum pan.

1 is a vacuum or evaporating pan in is placed. c

2 is a pipe in whichsuction is produced, this pipe being connected to the pan 1 to normally produce a vacuum therein, and to 35 a suction pump, 2 is provided with valves 3 and t spaced apart along the pipe, and is connected to the drying receptacle hereinafter described.

' The'vacuum or evaporating pan 1 may be supported in any suitable manner and may be of any desirable form, size and construction, and as the construction of said pan and its support forms no part of this invention, further description or illustration thereof is deemed unnecessary.

5 is a drying receptacle for the material,

as salt crystals, precipitated in the pan 1, and this means for conveying the preci 'itate from the pan 1 to the drying receptacle.

9 The. conveying means 6 may be of any desirable form, size and construction.

' The drying receptacle 5 is supported in any suitable manner, is preferably bellshaped or larger at its lower end than at its upper, and is formed with a neck 7 at its top-and with a movable bottom 8. Said which the liquor tojbe evaporated,.as brine,

not illustrated. Said pipe neck 7 is provided with a hopper 9, arranged beneath the exit 10 of the conveying means, and with a valve 11. Said receptacle is also provided with a'substantially horizontal perforated partition 12. As

shown this partition 12 is carried by the movable bottom 8 in order that when the bottom is moved out of its normal position, the partition will also be carried therewith. for permitting the salt or other precipitate to be removed from the receptacle.

The movable bottom 8 swings laterally out of its normal position on an upright pivot 13, the axis of which is located outside of, or eccentric to, the receptacle 5, and said bottom is formed with downwardly-converging Walls 14; arranged below and spaced apart from the partition 12 and with an outlet 15 at the lowest portion thereof, the axis of the outlet being substantially coincident with the axis of the pivot 13. Said bottom is held in its closed position by fastening members or clamps 1G, each'oi' which extended vertically'through alined cutouts 17,18 formed, respectively, in an outwardly-extending flange 19 at the lower end of the major partyof the receptacle 5 and in the margin 20 of the movable bottom, each fastening member 16 having a shoulder as a nut 21 at its lower end, which engages the lower face of the margin 20 of the bottom 5, and each. member 16 being connected at its upper end to cam 22 which bears on the upper face of the flange l9 and which operates to move said member 16 endwise. The pivot 13 is also provided with a nut 21 .at its lower end and with a cam 22 at its upper end. The bottom is also provided with rollers 23 which are carried by brackets 24; and which engage an arc-shaped track 25 when the bottom is moving into or out 0t its normal position this track 25 being, concentric with the pivot 13. The outlet 15 of the bottom is connected to the vacuum pan 1 in order that the saturated liquor in the receptacle may be drawn hrough the perforated partition 12 and returned to the vacuum pan 1 by the vacuum in said pan; and here illustrated, said outlet 15 is connected by a pipe 26 to the suction pipe it,

between the valves 3 and 4 in the suction pipe this outlet ppe 26 being provided with a valve 2?. The joint between. the outlet15 and the outletpipe 2G is of such construction as to permit the outlet 15 to turn or swivel in the outlet pipe 26, and as shown the out too bushing 30 is located between the outlet 11' into the receptacle ally and the dry precipitate is and the inner face of said outlet pipe.- Means as a. pipe 31, which is connected to a compressor tank 32, is provided, for co. uducting a drying fluid, as compressed err, to the receptacle ,5, said pipe being provhiled with a valve for controlling the {low of air therethrough, and being connected to the drying receptacle 5 at the top thereof.

In operation, when the receptaclebeing filled with the precipitate, the valves 3 and l-in the suction pipe are opened in order-that a'vacuum may be maintained in the evaporating pan 1, the valve 11 in the neck 7 of'the receptacle is opened, and the valves 27 and located, respectivr-sly, in the outlet pipe 26 of the receptacle 5 and in the compressed 'air pipe 31, are closed. When the receptacle 5 is filled, the valve ll is partly closed, the valve 27 in' the outlet. pipe .26 isopened, the valve. 25in the suction pipe 2 between the vacuumpan and the outlet pipe 26 is left open, and the valve at in the suction pipe 2 is closed, thereby permitting the moisture and saturated liquor to be drawn from the drying receptacle 5 intc the vacuun'r pan l by the vacuum in said pan.

The saturated liquor having," been drawn oil from the receptacle L the valve 37 in the outlet pipe 26 remains open, the valve 3 and the valve 11 are closed, and the valves t and 33 located, respectively, viln-tlie suction pijc 2 between the outlet pipe 2'? and the vineuiun pump, and in the compressed air pipe ll. are opened, so that comprcs l air, which usually has been previously heated, passes and through lhe pro- U cipitate therein, thus drying the 1::rcclpita and then passes out of the eceptaclc .3, through the outlet pipe to the pump. After the drying operation is pleted, the movable bottom swung lateruuiped into carts or other convcyers.

My apparat s is particularly advantageous in. that the sa tureted liquor is returned to the vacuum pan directly from the drying receptacle, and further in' that the salt or precipitate can be dried and prepared :t'cr shipment, much more quickly and eccnoi'uically than by methods hcilctofore in use.

1. The combination of a vacuum pan, a pipe in which suction is produced, con nected to said pan for creating a vacuum therein, a valve in said pipe, a drying receptacle for the material precipitated in said pan, means for conveying the precipitate from the vacuum pan to the drying receptacle, and an outlet pipe for the liquor drawn from the precipitate in the receptacle, said outlet pipe connecting the drying receptacle and the suction pipe, and communicating with the sucticnpipe at a point between said vacuum pen said valve, substantially as and for the purpose forth. l.
