50166867, May 21, 1991

Filed:

Oct 6, 1989

Appl. No.:

7/418064

Inventors:

Ralph Gerstenkorn - Garden Grove CA

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

B65G 6532

US Classification:

141 96

Abstract:

Methods and apparatus for loading particulate materials, in particular calcined coke, into a transport vehicle are disclosed, wherein the loading operation under steady state conditions is carried out in a "plugged chute" mode, so that a major portion of the loading chute is maintained in a filled condition with the particulate material being loaded. In this manner, the product drop height is maintained at an acceptably low level so as to reduce the velocity of the particulate material throughout the loading process below a damaging rate and thereby prevent significant degradation of the material. In a preferred embodiment, the major portion of the loading chute comprises a telescoping chute arrangement and level control means located above the major portion of the loading chute is employed to maintain the chute in the plugged or full condition by regulation of the discharge valve when the telescoping chute arrangement is fully extended. Conventional level control means located near the discharge end of the major portion of the chute may be employed during particular phases of the loading operation (in particular, when the telescoping chute arrangement is retracted). Switching means is suitably provided to permit instantaneous change from the plugged chute loading mode to conventional loading.

Abstract:

A rotary drum cooler for cooling particulate material (e. g. coke particles) having at least one cooling pocket which, in turn, includes a flexible vent pipe assembly which can slide in relation to the shell of the cooler. By making the vent pipe slidable, it can move in response to the expansion and contraction of the pocket within the shell. The vent pipe assembly is comprised of (a) a tube which is connected to the pocket and which slidably extends through an aperture in the shell and (b) a flexible means for sealingly connecting the outer end of the tube to the shell.

International Classification:

C10B 3910

US Classification:

202227

Abstract:

Apparatus for cooling granular material such as petroleum coke comprises an elongated drum characterized by a generally cylindrical shell wall having spaced apart circular segment pockets extending radially inwardly from the shell wall toward the central axis of the drum to provide extended heat transfer surfaces and flow spaces for cooling water. The cooling pockets are welded to the shell wall along the edges of opposed sidewalls of the pocket or conduit members themselves. The somewhat flexible drum shell resulting from the aforedescribed construction is strengthened and held substantially rigid for rotation about its central axis by a plurality of circumferentially spaced tension rods which extend from one end of the drum to the other and are engagable with a support plate. A plurality of coil springs are circumferentially spaced about the support plate and are compressed between the support plate and a flange of the drum to uniformly distribute compressive loads on the drum to minimize cyclical bending stresses on the drum during rotation thereof.

US Classification:

202229

Abstract:

A rotary drum cooler having a shell for cooling particulate material (e. g. coke particles) wherein the volumetric capacity of the lifters within the shell which lift the material from the bottom of the shell to the exit thereof can be adjusted to thereby affect the exit parameters (e. g. temperature, particle size, etc. ) of the cooled particulate material.

Appl. No.:

8/395057

Inventors:

Ralph Gerstenkorn - Bellingham WA
Leslie J. Okonek - Bellingham WA

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

C10B 3910

US Classification:

202227

Abstract:

A rotary coke cooling drum is formed of plural opposed folded plates welded together and having spaced apart openings for receiving an array of tubular cooling pockets which are separately formed and are insertable in the openings to provide heat transfer surfaces and auger flights for traversing material through the drum. The cooling pockets are formed by opposed trapezoidal shaped plate members which are welded to each other along mating edges leaving one end of the cooling pocket substantially open and the opposite end is closed over a major portion by an end cap and a short section of drain conduit adapted to project through the wall of the drum shell. The cooling pockets may each have a locating and mounting flange or doubler plate secured at the open end of the pockets and adapted to be welded to the wall of the drum shell. The pockets are easily inserted in and removed from the drum shell for repair or replacement as needed.
