A'pplication filed April 26, 1916. Serial No. 93,5542
provements in Comover-Elbows, of which the following is a specification.
This invention relates m pneumatic conveyers for the conveyance of ashes, sand and other abrasive and disintegrated materials, and more especially to the conveyor conduit elbow carrying the nozzle for the introduction of st mm or fluid under pressure to the conveyor conduit interior.
An object of the invention is the etl'ectual and complete protection of the suction elbow against wear by the use of improved tubular wear liners. A further object is the provision of improved 11 cans to enablethe ready replacement of worn wear linerswithout the removal of the elbow itself from the conduit. line. A still furtherobject is the production of an elbow having an apcrtured wear liner through which the fluid under pressure is introduced. Other objects will be. mentioned and described herein from time to time.
The preferred ei'nbodinient of the invention is disclosed in-the accompanying drawings. wherein Figure 1 is a longitudinal section in elevation; Fig. 2 is a section on the. line 2-2 of Fig, 1; Fig. 3 is a view in side elevation of the cover plate in reduced sizc; Fig. l is a side view oi theelbow showing all wear liners and the cover plate removed; and Fig. 5 a section showing a slight modification.
Similar numerals refer to similar members and parts of members throughout the several views on the drawings.
Referring tr the drawings in detail. the numeral 1 indicates the elbow bod provided with intake and discharge openings 2 and 3, respectively the former having the conventional flange 4. The numeral 5 indicates a wear liner insertion opening formed in the side "of the elbow body and extending from a point therein adjacent the intake flange 4 around the elbow bend to a point intermediate. the. elbow bend terminus and the dis charge openin The opening 5 is normally divided into the bend portion 6 and the straight portion -'7, the latter being somewhat larger diametrically than the portion 6. The numeral ,8 indicates the lateral flange of the insertion opening 5, substantially cothe elbow bend extensive therewith and provided. with the flat face, or surface, 9 the bolt holes 10,
10. The numeral 11 indicates a cover plate for sealing the opening 5 and adapted to be held in position against the face 9 by the bolts 12, 12 detachablv engaging the flange 8.. The numeral 13 indicates a boss formed at the bend of the elbow exterior substantially midway thereof and provided with a nozzle aperture ll which is substantially in axial alinenient with the discharge opening 3. The numeral. 15 indicates a nozzle for fluid under pressure. preferably steam, rigidly but detachabl a rranged within the aperture 14. having its issuing: end substantially in axial alinemcnt with discharge opening and connected with pipe 16 leading to a source of steam supp y.
The numeral 17. indicates a tubular removable weai liner at 'anged within the elbow bend at the intake and extending tor a fraction of the bond length to the end of the removable tubular medial liner 18. the latter covering length. The numeral 19 indicates an inlet aperture formed in the outer wall ot the tubular liner il and in registry with the boss aperturc ll to. permit the steam blast from the nozzle 15 to enter the elbow interior. The nunnt als 20 and 21 indicate. tubular wear liners removably arranged within the elbow enlargement and forward of the bend terminus. :h of which is somewhat thicker than the liner members 17 and 18. To accommodate liner member 21 the elbow extension bore is diametrically substantially the same as the enlargement T. In micration. the liners 20 and 21 take the impact of the steam blast and the abrasive action of the materials cast or projected by the steam before the latter is blown out of the discharge opening it therchv causing excessive wear within the longitudinal limits of said wear liners. For this reason, it is desirable to thicken the liners 20 and 21 to The liner 18- the cove:- plat= ll in position, the plate 11 is in position, after tastening provided with tion 22, o a series l er, each of winch thereof for ea engages a lnwr. obvious that other to for this accomt i n'icans may be resorted plislnnenl, such as a set. screw, or the like. At Fig. 5 a plain nnaperiured liner 18 is shown for use when the elbow is utilized merely as a lined elbow and without the nozzle 15.
