SEPARATING CONE FOR MATERIAL AND LIQUID SEPARATION Filed July 51, 1952 IN VEN TOR:
A TTORNE X United States Patent O SEPARATING CONE FOR MATERIAL AND LIQUID SEPARATION Harold B. Large, Los Angeles, Calif.
Application July 31, 1952, Serial N0. 301,945
6 Claims. (Cl; 209-211) This invention is a materials separator and the general object of the invention is to provide an apparatus for the purpose of separating materials, such as ores and liquids, and liquids of different specific gravities, by using centrifugal force as the separating medium engendered within a conical chamber.
Other objects and advantages of the invention will appear hereinafter as this specification progresses.
The invention is illustrated in the annexed drawing, which forms a part of this specification and in which:
Fig. 1 is a vertical longitudinal section of an apparatus embodying my invention taken on line 11 of Fig. 2.
Fig. 2 is a horizontal section of my invention taken on line 2--2 of Fig. 1.
Fig. 3 is a horizontal section of my invention taken on line 3-3 of Fig. 1.
Referring more particularly to the drawing, in which the same parts are designated by the same reference characters in all of the figures, my invention includes an inverted conical chamber 1 and an uppermostspiral duct guide housing 2, said chamber being formed in two sections, comprising a lower smaller frusto-conical section 3 and an upper larger frusto-conical section 4. On the upper edge of the lower section 3 is formed an external annular flange 5, and on the lower edge of the upper section 4 is formed an external annular flange 6, which coincides with and rests upon said flange 5, and said flanges 5 and 6 are detachably bolted together by bolts 7 and nuts 8, whereby the upper section 4 of the chamber 1 1S detachably secured at its lower end to the upper end of said lower chamber section 3.
To the lower end of the lower section 3 of the chamber 1 is secured a gland 9 formed with an external annular flange 10, through which flange a plurality of bolts 11 are extended downwardly in spaced circular relation around said flange 10. A slide gland 12 is formed with an external annular flange 13 disposed a short distance below said flange in vertical alignment therewith, through which flanges 10 and 13 the bolts 11 extend, and nuts 14 are fitted on the lower ends of said bolts against the lower side of the flange 13 of said lower gland 12, whereby said lower gland 12 is detachably suspended from the upper gland 9. An adjustable funnel 15 formed with an elongated depending outlet tube 16 is disposed within the lower part of the chamber 1, with said funnel tube slidably fitted in and extending through the glands 9 and 12 of the inverted lower conical chamber section 3. On the lower end of the funnel outlet tube 16 is located a middling outlet valve 17 for controlling the discharge of the separated material from said lower end of said funnel'outlet tube 15.
In the spiral duct guide chamber housing 2, above the upper end of the upper section 4 of the inverted conical chamber 1, is mounted a stationary spiral duct guide chamber 18 the spiral wall 19 of which is secured at its peripheral edge 20 to the inner side of said housing 2, preferably by welding said peripheral edge to said housing, while a central overflow pipe 21 extends upwardly centrally in the chamber 1 from a short distance above the funnel 15 through said spiral guide chamber 18, through the upper wall 22 of the housing 2 and through a pair of superimposed glands 22a and 23 above said upper wall 22. The glands 22a and 23 are formed with external annular flanges 24 and 25, respectively, and said glands are bolted together in superimposed spaced relation by bolts 26 and nuts 27. To the upper end of the overflow pipe 21 is connected an outwardly Patented Apr. 12, 1955 ice - end of a downwardly-extending waste overflow pipe section 31.
A tubular inlet 32 extends tangently into the upper end of the spiral duct guide chamber 18, and a downturned elbow 33 is connected to the outer end of said outlet, while the lower end of said elbow is connected to the upper end of feed inlet pipe 34.
From one side of the lower end of the lower conical section 3 of the inverted conical chamber 1 leads a tubular concentrate outlet 35, to the outer end of which is connected one end of a downturned elbow 36, the lower end of which is connected to the upper end of a concentrate outlet pipe 37, and to the lower end of which pipe is connected a middling outlet valve 38.
The operation of my invention is as follows:
The slurry or pulp is forced through the feed inlet 34 by a material pump (not shown) into the upper end of the spiral channel duct guide 18 and downwardly through said guide out of the lower end thereof into the inverted conical chamber 1, in which, by the velocity of the pulp attained, a centrifugal action is created that forces the heavier particles of the pulp to the outer perimeter of said conical chamber 1. The funnel 15 extends from the extreme lower end of the conical chamber 1 and is adjustable at the gland 9, so that the funnel may be placed in a position with relation to the lower end of the overflow pipe 21, where a desired separation of the materials can be made. The heavier particles of the material will by-pass the upper edge of the funnel and leave the conical chamber 1 through the concentrate outlet 35, elbow 36, concentrate outlet pipe 37 and middling outlet valve 38. The middlings of the slurry will leave the conical chamber 1 through the funnel 15, funnel outlet tube 16 and middling outlet valve 17. At the extreme lower end of the concentrate and middling outlets a molasses gate valve 38 is used to keep the products as lean of water as possible. The overflow is carried away from the conical chamber by the central overflow pipe 21 entering said chamber through the upper end thereof. The central overflow pipe 21 is adjustable at the upper gland 23, so that it can be raised or lowered to accomplish the desired result. The overflow is pulled up the overflow pipe 21 by suction created by elevating the conical chamber 1 a certain distance above the overflow outlet.
Applicant contends that his invention is better than any separator so far on the market, and that he has made an original invention in so far that he has three separations and particularly in the manner in which the concentrate is carried olf the side of the conical chamber at the bottom thereof. Then the use of the funnel that will make a closer separation as it can be brought to the extreme sides of the conical chamber, resulting in a very fine separation. A set of funnels that can be placed at higher elevations in the conical chamber are part of my invention.
I claim:
1. Apparatus for separating materials including an inverted conical chamber, a spiral guide duct located at the upper end of said chamber with its outlet end leading into said upper end of said chamber, and its inlet located at its opposite end to be connected to feed inlet means, a funnel formed with a depending outlet tube, said funnel being located in the lower part of said chamber with its said outlet tube slidably extending through the lower end of said chamber for adjusting said funnel up or down and the periphery of said funnel further away from or closer to the wall of said chamber, a concentrate outlet leading from ,the lower end of said chamber and an overflow pipe leading upwardly from a point above said funnel through said spiral guide duct and through the upper end of the apparatus.
2. Apparatus as claimed in claim 1 including glands on the lower end of said chamber through which the outlet tube of the funnel slidably extends.
