A preferred embodiment of a version of the invention refers to a container offload system for offloading commodities from a container.
Storing and transporting goods is essential to modern life. However, current methods leave much to be desired. Various types of containers and storage methods are used at different points in the process of loading, transporting, unloading, and storing commodities. This process takes significant time, puts the commodities at risk of contamination at each transfer point, decreases overall yield, and decreases profitability and productivity due to lost time and goods.
Many goods are shipped via intermodal containers (also known as ISO containers). Generally, there are several basic types of ISO containers. These include flat racks, open-top, insulated, reefer, and tank containers. Loading these containers is generally done by dumping material into the top, loading material into the front doors, or filling the container through an inlet pipe. Tank containers are built to the same standard dimensions as other ISO containers, but are made up of one or more vessels mounted inside of a rectangular steel framework (also known as an exoskeleton). Generally, these containers have been used to transport liquid or bulk materials. Presently, tank containers are rarely utilized for shipping or storing dry commodities.
Offload systems, particularly relating to those in shipping containers, storage containers, and silos, are responsible for offloading material or commodities from the shipping container, storage tank, or silo to another container or end user. The methods currently used for offloading shipping containers and silos are time consuming, expensive, and dangerous.
For example, manual offloading of sacked or bagged commodities is one method for offloading bulk commodities. This process takes a great deal of time, requires significant labor, and is susceptible to product contamination by dropping, tearing, or otherwise compromising the sacked commodities. Another method is tipping a loaded container. Tipping open-top and dry freight containers is the primary method used to offload bulk commodities from shipping containers. However, leveraging a fully loaded container high above the ground presents dangerous conditions. If a mechanical error takes place, especially when the container is lifted high off the ground, the results could be devastating. Additionally, in inclement weather it is difficult or impossible to keep the commodities from being contaminated by rain, wind, and other debris falling from the container doors, truck mud flaps, or top of container.
Once the commodities are offloaded from the shipping container, the bulk commodity may remain in a pit, or may be loaded into some other storage tank, such as a silo or bin. If remaining in a pit until needed, the commodity is exposed to wind, rain, and other elements, thus putting the product at risk of contamination. If the bulk commodity is loaded into a storage bin or tank, a great deal of time and effort must again be expended to load the material into the final storage container. Additionally, the process of loading bulk material into silos and other storage tanks requires large, heavy, and expensive equipment. Furthermore, the process of loading and subsequently unloading a silo or storage tank is dangerous.
Therefore, a needs exists in the art for an offloading system for shipping containers, storage containers, silos and other storage tanks that is safer, faster, and less expensive than current methods. Furthermore, there is a need for a container offloading system that simplifies product offload, increases shipping efficiency, and protects commodities from exposure to the elements. Additionally, there is a need for a system and method for loading, shipping, storing, and unloading dry bulk commodities in the same container. There is a further need for an intermodal (ISO) container capable of transport and onsite storage.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter. Nor is this Summary intended to be used to limit the claimed subject matter's scope.
A preferred embodiment of a version of the present invention is directed to a container offload system that satisfies the need to simplify product offload, increase shipping efficiency, and protect commodities. A further purpose of one embodiment of the present invention is to simplify the offload process based on a more efficient apparatus and process.
Nevertheless, embodiments of the invention are not limited to shipping containers, silos, and other storage tanks A version of the invention will generally find utility in any application that requires an efficient offload system for dry goods.
Generally, a preferred embodiment of a version of the invention comprises an offload system. Preferably, the offload system is made up of an upper section and a lower section. The lower section has a plurality of spacers connected thereto. The spacers are in contact with the commodity and allow controlled amounts of the commodity to pass through a gap between the spacers into a channel. The commodity is then offloaded from the container via the channel.
Some of the dry bulk goods consist of, but are not limited to, bauxite, bulk minerals (such as sand, gravel, copper, limestone, and salt), cement, chemicals (such as fertilizer, plastic granules, plastic pellets, citrus pellets, resin powder, and synthetic fiber), coal, dry edibles (such as alfalfa pellets, citrus pellets, livestock feed, flour, peanuts, raw or refined sugar, seeds, and starches), grain (such as wheat, corn, rice, barley, oats, rye, sorghum, and soybeans), iron (such as ferrous and non-ferrous ores, ferroalloys, and scrap metal) and wood chips.
Versions of the invention have many advantages over current systems. The following is a short set of advantages and is not meant to define all of the advantages of the versions of the present invention. One advantage of a preferred embodiment of a version of the invention is decreased contamination of commodity. Another advantage is that the commodity does not need to be transported from a shipping container to a storage container. Still another is decreased labor cost and time. Furthermore, the system has versatility in offloading various commodities. Additionally, the offload system can be retrofitted into existing containers. Furthermore, versions of the offload system may be retrofitted to fit in the hull of a marine vessel. Finally, the offload system of the present invention is safer than many current offload systems and methods.

In one embodiment of a version of the invention, a container offload system comprising a combination of at least two container offload systems is disclosed. As illustrated in
A preferred method of unloading a shipping container comprises filling a shipping container equipped with a container offload system described and claimed herein with a commodity. The filled shipping container is transported to an offload destination. At the offload destination, in one embodiment, a hose is attached to the offload system. Preferably, the hose is attached to a valve, which is in turn connected to the offload system. Once the hose is attached, a pressure change is created in the offload system. This pressure change may occur as a result of a wind velocity or vacuum. In one embodiment applying vacuum creates a pressure change. In another embodiment, a wind velocity, such as with a fan, creates a pressure change. The pressure change causes the commodity to move from the container to the offload system, from the offload system to the hose, and from the hose to the unloading area.
The offload system may be constructed from a wide variety of materials. Thus, it is understood that the invention covers the use of all materials. Preferably, the offload system will be comprised of strong metal such as steel. However, versions of the invention may be made of other metals. Additionally, versions of the invention are made of strong plastics and resins. It is understood that versions of the invention may be comprised of other materials, both natural and synthetic.
Furthermore, it is understood that the spacers may be made from any material. Preferably, the spacers are made of hardened rubber, metal, or plastic.
