Specification of Letters Patent.
lpplication filed November {3, 181?. $erial 1l1'o.200,$8l3.
To all whom it may con cern I Be it known that 1, CHARLES Tunes, a citizen of the United States, residing at Nogales, in the county of Santa Cruz and State of Arizona, have invented. new and useful improvements in Devices for the Aeration and Emulsifying of Pulp for Flotation, of Which the following is a specification.
This invention relates to a device for the aeration and emulsifying of pulp for fiotation.
An object of the present invention is to provide a simple, compact easily operated and cheaply manufactured, efiicient device for the aeration and emulsifying of pulp for flotation and particularly a form of apparatus which will eliminate the use of/power agitators, air pumps, and the like. Further objects will hereinafter appear.
The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed having reference to the accompanying drawings, in which Figure 3. is a side elevation, partly in section showing the form of apparatus employed.-
Fig. 2 is a front view. partly broken away and partly in section.
Fig. 3 shows a modified form of the distrihuter.
' Fig. 4 is a detail viewjshowing means for adjusting the naille plates.
Referring to the drawings in detail", A indicates a hopper or other suitable receptacle, to which the pulp to es treated is penstocl; 2. This penstocl; may be directly connected with a tube or other mill, or pulp from. a mill may be delivered directly to the hopper by a sand pump or other suitable form of elevator.
ing ol the pulp through the pipe 3 creates hopper a sufficient vacuum to draw air through the tubes 5 and thereby form a perfect mixture of air-and p111 I The pipe thus provided not only serves 11mcan be quickly erected and cheaply irled in a minimum of space in any p The oil or acid 1s added to the pulp wnile it is ground or it may be delive or may be adniittx 5, and a pert eznul :tiou and aeration takes place, it can rely be seen that the oil or other agent admitted. will be then oughly mixed. before the pulp enters the Spitzkasten where the froth is separated from the pulp and tailings.
While the pipe 3 may deliver the pulp directly to the Spitzlcasten, I prefer to interpose a combination distribute! and agitator constructed substantially shown in Figs. 1 and 2. This distributer consists of a iangular-shaped iii-ember including a pair of side walls 6 and 'l between which are suitably secured a number oi staggered baflle plates 8, the distributor being so proportioned arranged that no resistance when ever is impressed upon the pipe 3 through which the pulp flows. The Walls of the distributer preferably taper from the lower end to the top, being Wider at the top than more or less, below the surface level or overflow line in the $pihrasten.
While the distributes is here she ing triangular shape in front vious that any other suitable tributer may be employed. 'ture of importance tohe con' nection with the distribi that it has a capacity suificiently lar L} prevent any resistance to the discharge pulp through the pipe 8.
Any form of Spitzlrasiien may be employed for the separation. of the froth and tailings, a alve 8" being provided to regulate the discharge of the tailings and the overflow of the froth. 'Where composite ores are-handled it is obvious that the pulp may be run over or l'9'l.-Z.B&l8\l as often as necessary the presentapparatus being of considerable adtan 01s in that case as the simplicity of the construction and 3111*: gcment permits re-"reatment oi? the pulp to be readily taken care of. A ballle such as i in conshown at 9, may beemployed if desired,
, but it does not form any important feature of the present arrangement,
While the pipe 3 has here been shown as constructed of planks which are assembled to produce a pipe square'in cross section, it is obvious that itrmay be constructed of metal or any other material desired. I also struction may or break the joints,
to its fellow strip on the opposite side. An
- len th thereof so as to cause inixture of air escaped coating wish it understood that various changes in form, proportions and minor details of con be resorted to within the scope of the a pended claims and that I do not wish to imit myselfto the specific design and construction here shown.
By referring to Fig.3 it will be seen that the battles or distributing plates employed are secured alternately, one to each side wall ofthe j distributing box. This is of importance as when they are fastened to-' gather in this manner they will interlock. each strip with relation other feature shown in the modification is that each. strip is so secured, as shown at 1, that it may be manipulated or adjusted from the outside it the device should not distribute properly, therebg permitting the pulp falling (i 4 distributed and thoroughly agitated. Agithrough the xto be evenly tation at this point is of considerable im-j portance as it insures a perfect coating of all the metallic particles which may have during the previous steps of the operation.
Having thus described my invention, what I claim and desire to secureby Letters Patcut is'---- r 1. An aerator and emulsifier for flotation through which adapted to pass, air totthe pipe at points concentration comprising a pipe the pulp to be treated is and means for. admitting throughout the with the pulp throughout the entire passage "through the pipe otthe latter through the pipe.
2. An aerator and emulsifier for flotation concentration. comprising a vertically. positioned pipe through which the pulp to be treated is passed, and a plurality of tubes connected with the pipe throughout the length thereof through which air is admitted to aerate the pulp during its passage 3, An aerator and emulsifier for flotationconcentration comprising a vertically positioned pipe through which the pulp to and a plurality of up be treatedis assed, wardly eaten .ing, singularly disposed tubes connected with the ipe throughout the length thereof throulgl which air is admitted to aerate the p p during its passage through the pipe said tubes extending .said tubes extending" through the pipe sides and having their innerend's substantially flush with the inner face of the pipe, f
through the pipe sides and having their inner endssubstantially flush with the inner face of the pipe.
4. An aerator and emulsifier for flotation concentration comprising a hopper adapted to receive the pulp to be treated, a vertically positioned pipe connected with the bottom of the hopper, said tube having a plurality of air inlet openings formed therein ,throughout its length, and a pulp distributing and agitating member-connected with the lower end of thetube.
5. An aerator and. emulsifier for flotation concentration comprising a hopper adapted to receive the-pulp to be treated, a vertically positioned pipe connected with -the bottom of the hopper, said pipe having a plurality of air inlet openings formed therein throughout its length, a pulp distributing and agitating member connected with the lower end of the tube, said member comprising a pair of spaced plates, and a plurality of staggered superposed deflecting plates secured between the first named plates.
6. An aerator and emulsifier for flotation concentration comprising a. hopper adapted to receive the pulp to be treated,
a vertically positioned pipe connected with the bottom of the hopper, said pipe having air inlet openings formed" a plurality of thereinthroughout its length,a pulp distributmg and agitating member connected comprising a pair of spaced triangulartion to each. other, side members conne ct ing the triangular plates, and a plurality of staggered superposed deflecting plates secured between the triangular plates.
7, Adistributcr and agitator for flotation concentration composing a pair of spaced triangularshaped plates, distributing plates secured to each plate and ofi'set with relation to each other, and means for ad ustmgcharge, means to admit air to the pipe so as.
to cause mixture of air with the pulp throughout the passage of the latter through the pipe, and'a combined distributor and agitator connected to the discharge of the pipe. I
- with the lower end of the tube, said member 100 shaped plates disposed on angles with rela-' 4 10. In an aerator and'emulsifier for fi0 tation concentration, a puip conveying pipe, andmeans to admit air to said pipe by Suetion created by the pulp moving through 5 thepipe, said means being eonnected to the pipe so that the interior bf the latter 05ers no obstruction to the free passage of the pulp thereehrough. y
In testimony whereof I have hereunto set my'hand in the presence of two subscribmg 10 witnesses.
