UNITED STATES EDMUND SHAW, or
satin CLEANING AND Application filed Ma an,
My invention relates to a sand de-watering and cleaning device and particularly to such a device that is also adapted to classify or grade the sand.
It is a purpose of my invention to provide a sand cleaning device having a sand cleaning chamber that -is provided with means for supplying water thereto and which has an outlet for the sand near the bottom thereof, the-chamber being provided with means for controlling the discharge of the cleaned sand through said out-let which is operated automatically to assume different positions as the level of the sand in the cleaning chamber varies. The arrangement is preferably such that the clean water is supplied from a fioat chamber, located above the cleaning chamber, in which a float is located that controls the position of a valve at the outlet from the cleaning chamber through which the cleaned sand passes.
The water supply pipe is preferably flared at the bottom thereof and thus restricts the space between the walls of the cleaning chamber and the water supply pipe, whereby when the. sand reaches such a level that it fills in between the pipe and the wall of the cleaning chamber adjoining the pipe, the normal flow of the water upwardly out of the cleaning chamber is decreased, thus causing the float chamber to fill, due to the fact that aconstant supply of water is passing into the same, whereupon the float rises and the valve controlling the discharge of the sand is raised, causing the sand to be discharged from the bottom of the cleaning chamber.
It is another object of the invention to rovide a plurality of such cleaning chamhers wherein one chamber discharges the overflow from itself into a second chamber, and in view of the fact that the smaller particles will flow along with the water while the larger particles will settle to the bottom, this results in a grading or classifying of the sand so that the coarser sand will collect in the first of said chambers at the bottom thereof and the finer sand in the second chamber.- Obviously the number of chambers to be used may be varied in accordance with the number of grades desired.
Other objects and advantages of the mvention will appear as the description of the drawing proceeds. However, I desire to have it distinctly understood that I do not intend to limit myself to the exact details the rod 12.
1926. Serial No. 11Q,4,03.
shown or described, but that I intend to include as part of my invention. all such obvious changes and modifications of parts as would occur to a person skilled in the art' and as would fall within the scope claim. I In the drawing, the figure is a view partly n section and partly in perspective of my nnprovedsand cleaning and'classifying apparatus." Referring in detail to the drawings: A conduit 1 is shown, to which is secured a cleaning chamber 2 having an outwardly flared wall portion 3 and an inwardly ta-.
of the pe'red wall portion t forming a conical bottom for the charnben. The chamber is supported upon any suitable supporting means such as the legs and the conduit 1 is supported from the chamber 2. Mounted upon the top of the conduit 1 and supported by means of the legs (5 is a float chamber 7. A water supply pipe 8, having a valve 9, leads into said chamber 7 near the bottom thereof and a pipe 10 leads from the bottom of the chamber 7 into the cleaning chamber 2, said pipe having a flaring or conical lower end portion 11 which is open at the bottom thereof.
Mounted within the pipe 10 is a valve rod 12 on the upper end of which is mounted a float member 13, the same being adjustably secured in position on the rod 12 by means of the set s'crew 14. A guide bracket 15 is provided in the flaring part 11 of the pipe 10 for the rod 12 and a valve member 16 is mounted on the extreme lower end of The bottom 17 of the chamber 2 is provided with an opening 18 into which the valve 16 may seat so as to close the same.
A water pipe 19 having a valve 20 is also provided, leading into the chamber 2 near the bottom thereof, whereby the chamber may be washed when this is desired. the flushing operation being accomplished by opening the valve 21 in the flush pipe through which the water and contents of the chamber 2 may be discharged when desired.
Ordinarily the water flowing through the pipe 8 will pass into the float chamber 7 and down through the pipe 10 into the conical portion t of the chamber 2, mixing with the sand and water indicated by thenumeral 23 flowing in through the conduit 1 from the left of the chamber 2, and passing down- Wardly toward the conical bottom of said chamber. Thus the clean water passing awny throug the, P p will tend "t wash any mud or other undesirable matter out of the sand. At the same time the particles: of sand, particularly the coarser particles, will collect in the conical bottom 4 of the chamber 2 and will finally build up to the position shown in the drawing, the sand being indicated by the numeral 24. lVhen this occurs, the space between the flaring mouth 11 of the pipe 10 and the side wall portion 3 of the chamber 2 will be reduced and the flow of the water will be impeded, causing the level of the water, indicated by the numeral 25, in the tank 7 to rise, lifting the float 13 to the dotted position shown in the drawing, and raisingthe valve off its seat. to the dotted position shown therein, whereupon the sand 2% will discharge more rapidly through the opening 18.
After enough of the sand has discharged to increase the space between the flaring portion 11 of the pipe 10 and the wall portion 3,
the water will resume its original flow, and the float 13 w1ll go down, decreasing the 'discharge through the opening 18. The water with the particles of sand remaining therein passes upwardly through the upper portion pletely is when the sand carrying waterceases to How, or has a very small proportion of sand therein.
'1 he number of cleaning chambers may be increased if desired to catch still finer particles ot' the sand, although this may sometimes uot be necessary and is dependent upon the amount of grading of sand that it is desired to do.
It will be obvious that the sand collected in the bottom ol the chamber 2 will be coarser than that collected in the bottom of the chamber 2, and so on.
What 1 claim and desire to secure by Letters Patent is:-
1n a'device of the character described, a receptacle tor material to be cleaned, having a lower valved outlet and an upper overflow outlet, a cleaning lluidtank having a supply intake, a conduit leading from the tank into the receptacle and having a flared terminus above the valved outlet co-operative with material accumulated in the receptacle to variably restrict'ilow from said conduit to the overflow outlet, a lloat in said tank, a valve for the valved outlet, and a rod extending throughsaid conduit and connecting the float and the valve, whereby operation of the valve is effected by variation of level in the tank.
In testimony whereof I afiix my signature.
