R. G. LUNDY STEAM JET ATTORNEYS Patented Nov. 8, 1938 UNITED STATES PATENT OFFICE STEAM JET Roy G. Lundy, St. Louis, Mo.
Application September 20, 1937, Serial No. 164,790
2 Claims.
This invention relates to steam jets for lifts especially adapted for conveying particles of solid matter in water to a desired height and has for the primary object the provision of a device of this character which will reduce to a minimum the chances of clogging by particles of solid matter and will utilize a smaller amount of steam for the successful elevation of materials to a maximum height than required by jets now in use.
With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a vertical sectional view illustrating a steam jet constructed in accordance with my invention.
Figure 2 is a sectional view taken on the line 2-2 of Figure 1.
Referring in detail to the drawing, the numerals l and 2 indicate conveyor tubes, the tube 2 being located at right angles and in a plane above the tube l. The tube 1 acts to receive liquid and particles of solid matter and the tube 2 acts to discharge said liquid and particles of solid matter to a desired height. In order to cause the liquids and particles of solid matter to pass from the tube l and through the tube 2 my invention is employed which consists of a steam jet so constructed that a minimum amount of steam will develop sumcient lifting action to successfully assure the discharge of the matter and liquid at a maximum height.
The steam jet consists of a housing 3 having detachably secured thereto by bolts 4 fittings 5 and 6. The fitting 5 threads onto the tube 2 while the fitting 6 bolts onto the tube l and includes angularly related portions A and B. The portion B aligns with the tube I,v while the portion A aligns with the tube 2.
A sleeve 1 forming an orifice of a selected diameter is mounted. in the housing 3 with its uppermost end terminating within the tube 2 and the lower end has formed thereon an enlargement 8 of adiameter slightly smaller than the internal diameter of the housing 3 and is equipped with an adjustable packing gland 9 to establish a leak-proof connection between the housing 3 and the sleeve 1. A spider I is detachably secured on the housing and is adjustably connected to the sleeve 1 whereby said sleeve may be raised and lowered in the housing.
a steam chamber l 2 fed by steam from a supply,
pipe I3. The lower end of, the sleeve 1 is beveled and spaced from the cone-shaped member II a selected distance to form an annular steam orifice M which places the steam chamber l2 in communication with the interior of the sleeve 1. The steam from the chamber l2 escapes into the sleeve 1 in substantially conical formation exerting the greatest pressure next to the walls of the sleeve 1 and less pressure within the space centrally of the walls of the sleeve 1. A steam nozzle I is carried by the fitting 6 and has its discharge end terminating in the conical shaped member H and is arranged in axial alignment with the passage defined by the sleeve 1 and the orifice [2 of the conical shaped member ll so that a stream of steam will be discharged centrally through the sleeve 1 which with the conical shaped flow of steam by the orifice M will produce a maximum amount of suction in the fitting 6 and tube l for conveying the liquid and solid matter upwardly through the sleeve 1 into the tube I where the pressure of the steam carries said liquid and solid matter entirely through the tube 2 to a selected height without danger of the solid matter clogging the sleeve 1 or orifice l2 of the conical shaped member I l. Steam introduced into the sleeve 1 by the orifice l4 and the nozzle l5 requires a less amount of steam for the lifting of the'liquid and solid matter than fittings now in use with the chances of clogging reduced to a minimum.
The orifice l4 may be increased and decreased in size by adjusting the sleeve I relative to the conical shaped member II. The nozzle I5 is detachable from the fitting and different size nozzles may be employed to meet variable working conditions. It is preferable that the discharge end of the nozzle I5 terminate a distance from the orifice [4 which will equal the internal diameter of the sleeve 1.
What is claimed is:
1. A steam jet for lifts comprising a housing adapted to be connected into a conveyor tube and having an annular steam chamber connected to a steam supply, a sleeve having a uniform internal diameter extending downwardly in said housing and closing the upper portion of the housing, said sleeve being located centrally of the steam chamber, an inverted substantially conical-shaped member mounted in said housing and extending into the steam chamber from the lower end of the housing and having an orifice in alignment with the sleeve and spaced from the lower end of said sleeve to provide a conical-shaped passage between the steam chamber and the sleeve whereby steam discharging from the steam chamber into said sleeve will be in a conical-shaped flow for producing greater pressure adjacent the walls of said sleeve than axially thereof, and a steam nozzle for discharging steam axially through said conical-shaped member and axially through said sleeve with its discharge end located below the orifice of the inverted substantially conicalshaped member.
2. A steam jet for lifts comprising a housing adapted to be connected into a conveyor tube and having an annular steam chamber connected to a steam supply, a sleeve having a uniform internal diameter extending downwardly in said housing and closing the upper portion of the housing, said sleeve being located centrally of the steam chamber, an inverted substantially conical-shaped member mounted in said housing and extending into the steam chamber from the lower end of the housing and having an orifice in alignment with the sleeve and spaced from the lower end of said sleeve to provide a conical-shaped passage between the steam chamber and the sleeve whereby steam discharging from the steam chamber into said sleeve will be in a conical-shaped flow for producing greater pressure adjacent the Walls of said sleeve than axially thereof, a steam nozzle for discharging steam axially through said conical-- shaped member and axially through said sleeve with its discharge end located below the orifice of the inverted substantially conical-shaped member, a spider mounted in the housing and having the sleeve extending therethrough, and means for adjustably connecting the sleeve on the spider whereby the sleeve may be adjusted relative to the inverted substantially conical-shaped member to increase and decrease the size of the steam passage between the sleeve and the steam chamber.
