Abstract

A system for efficiently managing bulk material is provided. The description is directed to a portable support structure used to receive three portable containers of bulk material and output bulk material from the containers directly to a receiving hopper. The portable support structure includes a frame for holding three portable bulk material containers in an elevated position proximate the hopper, as well as a gravity feed outlet for routing the bulk material from the container directly to the hopper. The portable support structure is integrated into a trailer unit for easy transportation. The dimensions of the portable container and support structure are optimized for the following. • Maximum material mass per container while meeting DOT size and weight requirements without permit. • Maximum connected capacity on the support stand while staying within physical boundaries with respect to particulate flow. • 200 cubic foot per minute discharge rate. • Material with a bulk density in the range of 90 to 100 lbs per cubic foot.

OPTIMIZED BULK MATERIAL DELIVERY SYSTEM

ABSTRACT

A system for efficiently managing bulk material is provided. The description is directed to a portable support structure used to receive three portable containers of bulk material and output bulk material from the containers directly to a receiving hopper. The portable support structure includes a frame for holding three portable bulk material containers in an elevated position proximate the hopper, as well as a gravity feed outlet for routing the bulk material from the container directly to the hopper. The portable support structure is integrated into a trailer unit for easy transportation. The dimensions of the portable container and support structure are optimized for the following.

 Maximum material mass per container while meeting DOT size and weight requirements without permit.

 Maximum connected capacity on the support stand while staying within physical boundaries with respect to particulate flow.

 200 cubic foot per minute discharge rate.
 Material with a bulk density in the range of 90 to 100 lbs per cubic foot.

GENERAL DESCRIPTION OF THE BULK MATERIAL DELIVERY SYSTEM

In the past tank trucks have been frequently used to transport dry bulk material. Once the tank truck has reached the delivery site the material must be transferred from the tank truck into a supply tank. The bulk material is typically pneumatically transferred from the tank truck into the on-location supply tank (e.g., silo). The storage/delivery system may then deliver the bulk material into a hopper, from where it is metered into the process in which it is used.

Bulk material handling operations have increasingly began to use portable containers for transporting dry material instead of tank trucks. The containers can be brought in on trucks, unloaded, stored, and manipulated to when the material is needed. The containers are generally easier to manipulate than a large supply tank trailer, can be off loaded quicker since the material is not transferred from one tank to

another, and eliminates dusting and noise from pneumatic transfer. Once delivered to the site the containers are placed in a portable support structure for discharging the contents of the container.

The portable support structure provides an elevated location for three bulk material containers to be placed while the bulk material is transferred from the containers to the hopper. The support structure elevates the bulk material containers to a sufficient height above the hopper that there is enough potential energy available to transfer the bulk material directly from the containers to the hopper via gravity power. This eliminates the need for subsequent pneumatic or mechanical conveyance of the bulk material to deliver the material to the hopper. This improves the energy efficiency of bulk material handling operations at a job site, since no auxiliary power sources are needed to move the material from the containe...
