Bulk Material Storage And Reclaim System

US Patent:
2010027, Oct 28, 2010
Filed:
Apr 23, 2009
Appl. No.:
12/428888
Inventors:
Harold A. Walker - Jonesborough TN, US
International Classification:
B65G 47/00, B63B 27/00
US Classification:
414133, 4141409
Abstract:
Systems and methods for reclaiming bulk solid material from storage stockpiles or from watercraft. A storage and reclaim system includes a support surface for supporting a stockpile of bulk material. The support surface is defined by a plurality of individual material support structures geometrically arranged and positioned with reference to each other so that the support surface is essentially continuous. Each of the material support structures in turn includes a dish or funnel-like structure having a generally conical floor surface sloping towards an individual discharge opening fitted with a discharge control gate. An array of vibrators is mechanically connected to each of the material support structures so as to introduce vibrational energy into the dish or funnel-like structures sufficient to either avoid a stable reclaim cone or to destabilize a stable reclaim cone which may form in order to maintain material discharge flow.

Multiple Batch System And Method For Loading Railcars Of A Wide Range Of Capacities And Designs

US Patent:
7411136, Aug 12, 2008
Filed:
Jul 3, 2006
Appl. No.:
11/481174
Inventors:
Harold A. Walker - Jonesborough TN, US
International Classification:
B65G 67/04, B65G 67/06, B65G 67/22, G01G 13/00
US Classification:
177121, 177122, 414 21, 414328, 414809, 222 77, 141 83
Abstract:
Multiple-batch train loading systems and methods, for example for loading coal, which are capable of accommodating railcars of a wide range of capacities and designs. Each railcar is loaded with at least a relatively large initial weighed batch having a weight at least approximately equal to the maximum available capacity of a weigh bin, and a relatively small final weighed batch. The initial weighed batch and the final weighed batch are both made up with precision. If required, one or more intermediate weighed batches are loaded into the railcar. The intermediate batches, if required, are made up rapidly, but not necessarily with precision.
