Uni e St Patent APPARATUS FOR PUMPING SOLIDS Application August 24, 1953, Serial No. 376,215
4'Claims. (Cl. 302-37 My invention relates to pumps and equivalent devices which are capable of handling liquids and other fluent substances carrying considerable quantities of solids in suspension. It includes a novel kind of such apparatus and novel elements thereof, all of which cooperate to efliciently handle solids in suspension with a minimum of violent contact with the apparatus.
In an apparatus made'according to the principle of ,my. invention, the shaft on which the impeller is mounted .is hollowand serves to conduct the material thru the impeller-eye into the casing. The casing-wall opposite 'the one thru which the material enters the casing acts as a deflector, aids in guiding the material thru the casing, and this wall may be made removable, to permit easy access and removal of the impeller. The hollow shaft may be built in sections, to permit partial disassembly, for the convenient installation of belts, pulleys or other means of power-application.
This kind of apparatus is intended to be used primarily for handling solids in suspension. It can profitably be used in draining sumps and disposing of sewage, tailings,
storm-waters and waste-liquids generally, despite the suspension therein of considerable quantities of solids, e. g., trash, litter, manure and general refuse which would be more likely to clog and damage any pumps now used for such purposes. Such apparatus, made according to my invention, can with equal profit be used to handle solids by means of their suspension in more fluent media, e. g., such solids as sand, gravel, coal, mineral ores in process and many others. Because of its simplicity, it is easily adapted to provide ready access to the interior for cleaning and inspection and therefore particularly adapted to the handling of food-stuffs and foods in process of preparation, such as fruits, vegetables, fish, soups and innumerable others.
Some of the objects of my invention are to provide a kind of apparatus which will handle solids in suspension with less wear of internal parts, less clogging and less damage to apparatus or solids than is possible with conventional pumps now used for such purposes, and to provide such apparatus which is also eflicient, simple and easily built and maintained.
The principle of my invention is illustrated by the embodiment now described, with the aid of the drawings. My invention is of course not limited to such specific details as are here set forth, except by the claims themselves and any prior art. This embodiment is a pump, a longitudinal vertical section of which is shown in Figure 1. Figure 2 is an end-elevation.
Referring first to Figure 1, the hollow shaft is in two sections 10, 11. One end of the section enters the pump-casing 12 and has mounted on that end an impeller 13, held in place with the key 14 and the impellerloek-nut 15. The section 10 of the hollow shaft 10, 11 is mounted on a bearing 16 which is in turn supported by the bearing-support 17. Leakage of liquid from within the casing 12 during operation is prevented by the 2,785,930 re t r Mar .9. 95,?
. 2 packing 18, which is held in position by the adjustable packing-nut '19. a
In this embodiment, a drive-pulley 20 is integrally formed on one end of the section 10 of the hollow shaft 10, 11 and another pulley 21 is integrally formed on the adjacent end of the section 11, to transmit the necessary power for the rotation of the hollow shaft 10, 11 and the impeller 13. These pulleys 20, 21 are separably joined by means of circumferentially spaced bolts 22. The two sections of the hollow shaft 10, 11 and the two pulleys 20, 21 are separated by the gasket 23 to prevent leakage.
The hollow-shaft section 11 is mounted on the bearing 24, which is held by the bearing-support 25. Both of the bearings 16, 24 are automatically cooled by the liquid in the material being handled. The bearing-supports 17, 25 are mounted on a base-plate '26 and secured for alignment by the suitably-placed bolts 27.
The conveyance of the material into the rotating, hollow shaft10, 11 is achieved by means of an adjustable, stationary hollow-shaft-extension 28. This extension 28 is threaded to permit its being screwed into the bearingsupport 25 and against a packing 29. Clearance is provided between the stationary hollow-shaft-extension 28 and the rotating, hollow shaft 10, 11, and leakage thru this clearance is prevented by screwing the said extension 28 against the packing 29.
To facilitate the connection of the hollow-shaft-extension 28 with a fixed supply-line, not shown, without impairing the adjustability of the hollow-shaft-extension 28, a flange 30 is slidably mounted on the extension 28. The flange 30 is provided with a packing 31, held in place by the packing-nut 32, by which means leakage between the flange 30 and the hollow-shaft-extension is prevented.
The perimeter of the casing 12 is volute in form and is provided with two opposing walls 33, 34. The wall 33, thru which the hollow-shaft section 10 enters the casing 12, is recessed to receive the impeller 13. This wall 33, I will call the entrance-wall 33. The endwall 34, opposite the entrance-wall 33, is removable and substantially conical in form, with the cones apex 35 toward the center of the entrance-wall 33. The end-wall 34 is secured in position by circumferentially-spaced bolts 36. The opening created by the removal of the end-wall 34 is large enough to permit the removal of the impeller 13.
The said end-wall 34 serves as a deflector and tends to confine the flow of the material to its natural course, toward the eduction-channel 37. The apex 35 is spaced from the impeller 13 sufliciently to permit the passage of solids clear of the impeller 13. The end-wall 34 takes the wear that would be taken by the impeller of a conventional, centrifugal pump. Being simple in construction, the removable end-wall 34 can be cheaply replaced.
In Figure 2 are shown the casing 12, with its eductionport-fiange 38, the end-wall 34, with the bolts 36 securing it to the casing 12, and partially broken away to show the end of the hollow-shaft section 10, with the impeller 13 mounted thereon, the impeller vanes 39, the webbing 40 and the impeller-lock-nut 15, which is provided with holes for the insertion of the prongs of a wrench with which to remove the impeller-lock-nut 15.
