AGITATom APPLICATION FILED AUG.10, 1910. I 981,098. v Patented Jau. 10, 1911.
JASPER A. MCCASKELL, OF SALT LAKE CITY, UTAH.
y'Specication of Letters Patent.
Application filed August 10, 19'1'0. Serial No. 576,496.
T o all whom itmay concern:
Be it known tha't I, J AsrEn A. MCCASKELL, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented vcertain new and useful Improvements in Agitators, of which the following is a specification.
This invention relatesto slimes agitators, and particularly to apparatus designed to impart a circular motion to the slimes or solutions in a tank, caused by the tangential impetus given the solutions, by admitting the solutions under pressure at different points in the tank and in such a direction, as to cause a revolving of the solutions in the tank; at the same time admitting air under pressure around Ysubstantially the inner circumference of the tank and throughout the body of the solutions in the tank in an opfposi'te direction to that of the motion 0f the solutions, thus causing a most efficientaeration of the slimes in solution.
The invention consists of the parts and the constructions and arrangements and combinations of parts which I will hereinafter describe and claim.
In the accompanying drawings forming a part of this speciication and in which similar reference characters indicate like parts in the several views, Figure 1 is a vertical sectional View of a slimes containing tank embodying the salient features of my in-` vention, showingthe slimes circulating pipes" and air conducting pipes in side elevation. Fig. 2 1s a top plan view of Fig. 1.'
In carrying out my invent-ion I construct a tank, l0, of,` suitable shape, dimensions and capacity into! which tank the slimes or s0lutions to b e treated are conducted and are designed to be kept in constant motion by means which .I will now describe. These means include ia centrifugal or other pump, 11, having its discharge connecting with the lower portion of the tank, said pump con necting through its center with a pipe, 12, which leads to the upper end of the tank and is designed to conduct the voverflow from the tank to the pump so that said overflow may be pumped back into the tank through the distributing pipe at the bottom thereof,l
This distributing pipe, 13, is herein shown as being circularly arranged in or near the bottom of the tank, the inlet end of the pipe being coupled or otherwise connected to the discharge end of the pump and said pipe be- Patented Jaa-1o, '1911,
ing 'provided with a number of nozzles or I outlets, 14, placed to discharge tangential to the direction of the pipe, so that the whole mass of solution lin the tank is given a circular motion and th-e contents of the said tank are maintained in a constant state of agitation.
As shown in Fig. 1, an air pipe, 15, connects with the overovsr pipe, 12, thus admitting air from this pipe to the suction end of the pump for delivery with the luid'contents into the bottom of the tank.
A second pipe, 16, of circular or other form is placed Within the tank I above and substantially close t0 the first-named circular pipe, said secon-d pipe connecting with an air pipe,
17, which pierces the side of the tank, said,
second circular pipe being provided with a' series of tan'gentially arranged outlets,- which may be in the form of nozzles, 18, adapted to admit air in substantially an opposite di rection to the motion of the revolving slirnes in the tank, thus inducin a thorough aeratio'n of the whole mass o slimes.
As shown in Fig. 2, at the discharge end of the nozzles, 18, leading from the circular 'air pipe, 16', there is placed 'a small flap or of the invent-ion. It is also true that the circular character of the pipes, 13 and 16, may be changed and thesepipes iven a different j formation Without material y modifying the action of said pipes, but the circular arrangement shown and particularly the opposlte disposition of the discharges and the tangential discharge are thought to give the best results.
From the foregoing, it will be apparent that when the apparatus'is in action the solutions in the tank are given a circular motion caused by the tangential impetus induced by the arrangement of the outlets or nozzles and by admitting the solutions under pressure at. different points in the tank; and by admitting air under pressure around the periphery of the tank and` throughoutthe body of the solutions in said tank, and in an oppositev direction to that of the motion of the solutions, a most etlicient aeration and agitation of the slimes is effected.r
After the slimes are agitated in the tank, they are drawn ,olf and run through an a ppropriate lter press, not shown.
Having thus described my invention what I claim as new and desireto secure by Letters Patent is:
l. In an agitatin mechanism` for solutions, the combination of a solution-containing'tank, a solution-conducting pipe in the lower portion of said tank having outlets adapted to discharge the solutions tangentially at different points around the tank, to thereby induce a circular motion to the solutions, and a pipe extending around the tank having tangentially' arranged nozzles substantially opposite said outlets Afor admitting air to the lower portion of the tank at dlferent points, and tangentially -in a direction substantially opposite to the discharge 'of the solutions into the tank, and means tor circulating the solutions through said tank.
v 2. In an apparatus of the character described, the combination of a tank and a pipe in the lower portion thereof having loutlets arranged to discharge tangentially to thereby induce a circular motion to the Contents of the tank, and an air pipe within the tank having outlets at numerous points in the tank arranged tangentially with one substantially opposite a corresponding outlet in the tiret-named plpe, said second outlets adapted to discharge air under pressure in a direction substantially opposite to the delivery of the solutions into the tank, whereby the mass of material is thoroughly agitated andaerated, and means ,tion to the circular motion `with the pipe and with the upper portion of the tank, and an air-pipe above and proximate vto the solutions pipe, said air# pipe having outlets at various points adapted to discharge the air tangentially into the tank and substantially in opposiof the solutions, whereby the fluid contents of thoroughly agitated and atv the same time aerated.
4. In an apparatus of the character described, the combination of a tank, a cirthe tank are cular pipe in the lower portion thereof havn ing nozzles arranged at different points in its length, said nozzles adapted to discharge tangentially to thereby give a circular motion to the solutions, a pump connecting with the pipe and with the upper portion of the tank, and an air-pipe above and pipe having outlets at various points adaptedto lischarge lthe air tangentially into the tank and substantially in opposition'to the circular motion of the solutions, whereby the fluid contents of the tank are thoroughly agitatedand aerated, and valves carried by the nozzles ofthe air-pipe adapted to automatically close the outer ends ot the nozzles when `air pressure in the said pipe ceases.
-In testimon whereof I affix my signature in'presence o two witnesses.
