GRAVEL WASHER.
Application filed September 24, 1926.
This invention relates to improvements in gravel washers.
Gravel washers now in general use are open to the object-ion that they do not wash out sticlry clay from the gravel.
It is, therefore, the primary object of the present invention to provide a cylindrical screen gravel washer so constructedpas to efficiently wash out sticky clay and like foreign substances.
A further object ef the invention is to pro` vide a gravel washer having a scrubber in which the material is thoroughly churned up by lifting blades.
A further object of the invention is to provide a kgravel washer in which the larger boulders are retarded within a certain section and as the device revolves, the boulders perform a ball mill action to grind up any clay, shale, slate, or other soft rock in the aggregate.
A further object of the invention is to provide a gravel washer in which the sand and pebbles can not in any way retard and blanket the grinding agencies, or embed themselves in the clay to armor this material, and in any way retard or hinder the ball mill action. p
A further object of the invention is to provide a gravel washer designed to effec tively retain the large aggregate.
A further object of the invention is to provide a gravel washer in which sprays are introduced for the full length of the scrubbing section and the dirty water is flushed outas fast as it is used, and in which, as the material progresses toward the end of the scrubber, it is continuously flushed with clean water While the dirty water is flushed away.
A further object of the invention is to provide a gravel washer which is of very simple construction, is strong and durable, and is well adapted for the purposes described.
With the above and other objects in view, the invention consists of the improved gravel washer, and its parts and combinations as set forth in the claims and all equivalents thereof.
In the accompanying drawings in which the same reference characters indicate the same parts in all of the views:
Fig. 1 is a horizontal sectional view of the improved gravel washer;
Fig. 2, is a side view thereof;
Serial No. 137,494.
Fig. 3, is an end view thereof; Fig. 4, is an opposite end view;
Fig. 5, is a fragmentary detaill view partly p in section, and on a larger scale; and
Fig. 6, is another enlarged fragmentary detail view, partly in section.
Referring now more particularly tothe drawings, it will appear that the numeral 10, indicates a supporting structure having a bearing l1 at one end and a pair of bearing wheels 12 at the other end. The improved gravel washer, generally indicated by the numeral 13, is mounted longitudinally on said supporting structure and a shaft 14 mounted in a bearing 15 is journaled in the bearing 11 formed in the rear end of the gravel washer, The opposite end portion of the gravel washer carries an external, annular flange 16 adaptedy to ride on the bearing wheels 12. Hence, by means of the bearings and wheels, the gravel washer is revolubly mounted with respect to the supporting struct-ure.` i
The gravel washer `includes an inner elongated ycylindrical member 17 termed a washing screen and an outer cylindrical member 18 termed a jacket, the aclret being of less length than thewashing screen and mounted with respect thereto as shown in Fig. 2. The said members 17 and 18 are connected by means of angularv plates 19.
The inner or rear end of the washing screen is closed by means of a disc casting having attached thereto a bevel ring gear 2O adapted to mesh with a pinion gear 21 carried on a shaft 22 at right angles to the longitudinal plane of the screen, the shaft 22 being journaled in a bearing 23 carried by the end portion of the supporting structure 10. The outer end portion of the shaft 22 carries a pulley wheel 24 for connection with a source of power by means of a belt (not shown). Obviously, by means of the gears described, the gravel washer may be revolved. The forward or outer end of the washing screen is partially closed by a retainer ring 25 formed with a circular opening 26 of substantial size to permit the introduction of material into the screen. The interior of the screen is also divided by two or more retainer rings 27 and 28, forming a plurality of compartments 29, 30 and 31, the compartment 31 being of greater size than the other compartments.
The forward compartments 29 and 30 provide what is known as the scrubbing section and secured to the interior Walls of the screen forming the scrubbing section areY longitudinally extending lifting blades 32. The outermost portion of the screen forming the scrubbing section is unperforated, as at 88. The remaining portion of the screenv enclosing the compartments 29 and 8() is formed With a plurality of small apertures 34. The portion of the screen enclosing the large compartment 31, except for the extreme end portion thereof, is formed With a plurality of apertures 35 substantially larger than the apertures 84.
The outer acket 18 is formed in tWo sections 37 and 88 secured together by means of plates '36, as shown in Fig. 5. The portion 37' of the jacket Which covers the scrubbing sections of the Washing screen is provided with perforations 39 of a small size and this section of the member 18 provides a sand jacket. The section 38 of the member 18 is formed with larger perforations 40 to provide a fine gravel jacket.
The method of Washing gravel by means of the improved Washer is as follows:
rEhe improved gravel Washer is adapted for use in gravel plants and receives the material usually after it has passed through a Washing box. 'Ihe gravel Washer is revolved by means of the mechanism heretofore described and the material is introduced into the open end of the Washing screen into the compartment 29. It should also be understood that the material is subjected to sprays of ivater during its entire stay in the scrubbing section of the gravel Washer. In the scrubbing section or compartments 29 and 80, the material is thoroughly churned up by the lifting blades 32, and as it progresses toward the retainer rings 27 and 28, sand and dirty Water are flushed through the per forations of the scrubbing section and the sand jacket. The fine aggregate passes the sand jacket and is conveyed to other mechanism for further operations. The boulders and small pebbles are retained in the and the material is continually flushed With clean Water through the entire length of the scrubbingsection, provision being madel for the draining off of dirty Water. gravel Washer is of simple'and novel con- .truction, and is Weli adapted for the pur-y poses set forth.
What I claim as my invention is:
1. A revoluble gravel Washer, comprising a cylindrical perforated Washing screen, a cylindrical perforated jacket surrounding the screen, the perforations of both Ymembers being of graduated sizes and extending substantially the length of both members Whereby Water and material may be flushed therethrough at any point, transverse retainer rings Within the screen, and lifting blades Within a portion of the screen and extending longitudinally parallel with the axis of the screen.
2. In a revoluble gravel Wasl1er,'a cylindrical perforated washing screen having perforations of graduated sizes and extending substantially the length of said member whereby Water and material may be flushed therethrough at any point, transverse retainer rings Within the screen and dividing it into a scrubbing section and a gravel section, the Yrings serving to restrict the removal of large material from the scrubbing section to the gravel section, longitudinally extending lifting blades Within only theY scrubbing section and extending parallel with the axis of the screen, and means for revolving the gravel Washer. Y
In testimony whereof, I aiix my signature.
