Dec 20, 2001

Appl. No.:

10/027500

Inventors:

Merton L. Dibble - Kingsport TN
Ronald K. Dailey - Johnson City TN
Robert R. Stanley - Church Hill TN

Assignee:

Eastman Chemical Company - Kingsport TN

International Classification:

B65G 5358

US Classification:

406 83

Abstract:

A device for establishing an optimal material flow rate through a material convey line in which a pressurized fluid flow is used to convey material entrained within the fluid passed through the convey line is disclosed. The device includes a plate defining an orifice therein, and a latching mechanism for detachably connecting the plate to an o discharge opening of the material convey line. A gasket is disposed on a first side of the plate and extends along the periphery thereof, and is adapted to be received on and sealed to the discharge end of the material convey line when connected thereto by the latching mechanism such that the fluid flow may pass through only the orifice within the plate. The orifice is sized and shaped to establish a fluid flow backpressure within the material convey line, when the plate is connected to the material convey line, which equates generally to the transport of material therethrough for optimizing the fluid flow parameters within the material convey line without having to otherwise pass the entrained materials therethrough. The device also includes an elongate tubular body having a first end and a spaced second end, the orifice plate being affixed along its first side to the second end of the tubular body.

International Classification:

US Classification:

209638, 209631, 209637, 209640, 209133, 209135

Abstract:

A classifier for classifying particulates entrained in a flowing stream of gas is configured such that a change of direction of gas flow causes particles to impinge upon a target, heavier particles being trapped in a downwardly extending fluidized trap. The classifier is easily constructed, has no moving parts, and can take the place of sifters and other equipment traditionally used for classifying such product streams.

International Classification:

B65G 5300

US Classification:

406197

Abstract:

A method and apparatus for establishing the proper gas flow to pneumatically convey materials from a storage location. The device includes a plate of a size to be complementarily received over a discharge end of a convey line and connected thereto. The plate defines an orifice extending therethrough so that the orifice allows fluid communication between the convey line and atmosphere. The system blower then is used and the speed of the blower is set to establish a predetermined pressure. The blower is stopped, the device is removed, and the blower is restarted at the same speed as set using the device, which is the optimal unloading gas flow for that material.
