Application February 26, 1931, Serial No. 518,583 Renewed April 26, 1934 1 Claim.
The present invention relates to a coal cleaning machine and has for an important object to provide, in .a manner as hereinafter set forth, a machine of this character embodying a novel construction and arrangement of parts whereby water is utilized to effectively remove or separate slate, rock and other foreign matter from the coal.
Other objects of the invention are to provide a coal washing machine of the character described which will be simple in construction, strong, durable, efficient and reliable in operation and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a View in front elevation of a coal cleaning machine constructed in accordance with this invention.
Figure 2 isa View in top plan thereof.
Figure 3 is a view in end elevation of the machine.
Figured is a View in vertical cross section through the cleaning or separating table.
Figure 5 is a detail View in perspective of one of the baffles.
Figure 6 is a detail view in perspective showing the adjustable means for movably supporting the table.
Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a supporting structure or frame upon which the transverse rods 2 are journaled in the bearings 3 adjacent the ends of said supporting structure or frame 1. Links 4 are mounted on the end portions of the rods 2 and are adapted for swinging movement in a vertical plane, said links being disposed in transversely aligned pairs and having extending therebetween the rods 5. The rods 5 extend through the vertically disposed metallic bars 6 having hingedly connected to their upper edges the elongated fiat metallic plates 7 having slots 8 at spaced points therein (see Figure 1) in which are operable bolts which project from the adjacent sides of a hopper 9 which is supported between the plates '7. The bolts which project from the hopper 9 are operable in the slots 8 to permit adjustment of the hopper. Nuts are, of course, threaded on the hopper securing bolts as clearly seenin Figures 1 and 3 of the -drawings for securing the hopper in adjusted position, said nuts being engageable with the plates 7. The plates 7 are hingedly connected to the bars 6 as at 10.
A diagonally inclined perforated plate or table 11 is detachably bolted, as at 12 on the top of the 1 hopper '7 and saidplate or table projects beyond the marginal edges of the hopper, as illustrated to advantage in Figure 4 of the drawings. A trough 13 is provided at one end of the table 11, said trough being transversely disposed and inclined and said trough further progressively increasing in size toward the said discharge end. The side portion of the table 11 which is adjacent the discharge end of the trough 13 is directed downwardly in a mamier to provide a lip 14. The 701;; other end and the adjacent portion of the longitudinal sides of the table 11 are provided with upstanding walls 15 and 16, respectively, the walls 16 terminating in spaced relation to the end of the table 11 at which the trough 13 is disposed. L. An intake chute 17 is provided at the uppermost corner portion of the table 11.
Diagonal bafiies 18 are mounted on the perforated table 11 and are disposed as best seen in Figure 2 of the drawings. The baifies18 comprise a base portion 19 and an upstanding blade 21 which, as seen in Figure 5, progressively increases in height from one end to its other end. This progressive increase in height of the upstanding blades 20 of the baffles 18 is to partially compen- 35 sate for inclination of the table 11 from the intake end of said table to the discharge end thereof.
A diagonally extending plate 22 is provided above the bafiies l8 and extends from the free end of the upper portion wall 16 to a point adjacent the 901. inner side of the trough 13 and adjacent the discharge end of said trough 13.
A pair of chutes 23 and 24 are mounted on the supporting structure or frame 1 and disposed beneath the trough 13 and the discharge lip 14 951': respectively. Screen sections 25 are provided in the chutes 23 and 24 for a purpose which will be presently set forth.
As illustrated to advantage in Figure 6 of the drawings, the links 4 are each in sections which are oppositely threaded and connected together by a turn buckle 26 through the medium of which the links may be lengthened or shortened to raise or lower either end of the table 11. The mounting of the hopper 9 on the plates 7 through the medium of the slots 8 is designed to permit either side of the table 11 to be raised or lowered. It will thus be seen that the table is mounted in a manner to permit universal adjustment thereof for disposing the same at any angle or inclination desired.
The reference numeral 27 designates an electric motor having its armature shaft extending from the opposite ends thereof, said armature shaft being designated by the reference numeral 28. A pulley 29 is fixed on one end portion of the shaft of the motor 27. A crank shaft 30 is journaled for rotation in the bearings 31 which are mounted on the supporting structure or frame 1 and said crank shaft is operatively connected to the adjacent rod 5 by a pitman 32. A pulley 33 is fixed on one end portion of the crank shaft 30 and an endless drive belt 34 is trained over the pulleys 29 and 33 for operatively connecting the crank shaft 30 to the electric motor 27. The motor 27 also drives a centrifugal water pump 35 having connection with a suitable source of supply through the conduit 36. An outlet pipe 3'7 is connected with the discharge of the pump 35 and has interposed therein a control valve 38. As best seen in Figure 4 of the drawings, the outlet or delivery pipe 37 is connected with the lower end of the hopper 9 and has connected thereto a spray head 39 which is disposed in the hopper 9. A flexible hose section 40 is also interposed in the outlet or delivery pipe 37 to permit shaking of the cleaning or separating table.
In operation, the coal in an uncleaned state or condition is deposited on the perforated table 11 at the uppermost corner portion of said table where the intake chute 17 is located. The electric motor drives the crank shaft 30 which, in turn, shakes the table 11 through the medium of the pitman 32, as will be readily understood and the uncleaned coal is distributed by gravity on the table 11. Water under pressure is discharged into the hopper 9 by the pump 35 and said water passes upwardly through the perforations in the table 11 with sufficient force to above the baffles 18 from passing into the trough 23 and 24 and, if desired, a suitable receptacle may be disposed beneath the screen sections 25 to receive the water and return said water to the pump 35 or to a suitable tank from which the water may be drawn by the pump 35. The perforations in the table 11 may be of any size suitable for the coal which is being handled in the machine.
It is believed that the many advantages of a coal cleaning machine in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall within the scope of the invention as claimed.
What is claimed is:
A cleaning device of the class described comprising a table sloping downwardly from its inlet end to its discharge end and also sloping downwardly from one side to the other side, a chute for delivering material to be cleaned at the high corner of the table at the inlet end thereof, a trough at the discharge end of the table, an upstanding flange at the high side of the table and extending from the high side of the trough to the discharge end of the table, said flange having its rear part of less height than its front part to form a shoulder at the junction of the low part with the high part, said shoulder being located an appreciable distance from the discharge end of the table, a diagonally arranged upstanding plate having its upper end connected to the shoulder and said plate extending to the low corner of the discharge end of the table, with its lower edge spaced from the table, an upstanding flange at the low side of the table terminating an appreciable distance from the discharge end thereof, a downwardly sloping lip or chute connected to the low side of the table and extending from the rear end of the last-mentioned flange to the discharge end of the table and diagonally arranged spaced bafiles on the table extending from a point adjacent the inlet end to a point adjacent the discharge end, and sloping upwardly towards the high side of the table, said table having perforations therein and means for forcing fluid through said perforations, each bafile gradually increasing in height towards the discharge end of the table, and passing under the plate.
