This application claims priority to and the benefit of co-pending U.S. Patent Application No. 62/830,956, entitled “NESTABLE DRUM SYSTEM, filed on Apr. 8, 2019, the entire contents of which are hereby incorporated herein by reference.
BACKGROUNDIn various facilities, mechanical components are cleaned using chemical solutions to remove grease, dirt, and other debris. The cleaning solutions used may include harmful elements. Typically, metal containers are used to store these chemical solutions during shipment and during the process of cleaning the mechanical components.
Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, with emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The present disclosure relates to a nestable drum assembly for storing potentially hazardous liquid and cleaning mechanical components. Within a facility, mechanical components may be cleaned using chemical solutions to remove oil, dirt, and other debris. The cleaning solutions used may include a surfactant blend, a caustic blend, or other harmful compounds. Typically, metal containers are used to store these chemical solutions during shipment and during the process of cleaning the mechanical components. For example, a typical metal container may be a fifty five gallon steel drum. However, these metal containers take up a considerable amount of space when shipped in bulk. Additionally, these metal containers can rust and leak eventually from exposure to chemicals, biologicals and moisture.
The embodiments of the present disclosure relate to a drum assembly that enables multiple drums to be nested. The nested arrangement of drums reduces the amount of space occupied by multiple drums in comparison to existing drums improving shipping, storage and cost of drum. A nested arrangement of the drums can represent at least a portion of a drum being placed within another drum. In contrast, stacking two drums may involve placing the bottom of a first drum on top of a second drum. The nested arrangement occupies less space than a stacked arrangement because the overall height of multiple drums is reduced in the nested arrangement. Further, the drum assembly include additional structural components that improve upon the storage and transportation of fluids. Depending on the contamination and ability to recycle contaminants in the drum, the drum can be cleaned out and reused or recycled.
With reference to
The drum 103 can be made from a variety of materials that can support the storage of harmful and non-harmful materials. For example, the drum 103 can be comprised of a variety of different plastic materials that are suitable for storing and transporting chemical cleaning solutions. Some non-limiting examples of plastic materials may include (PP) Polypropylene, (PE) Polyethylene (LDPE) Low Density Polyethylene, (LLDPE) Liniar Low Density Polyethylene, (HDPE) High Density Polyethylene or other suitable materials. In one non-limiting example, a wall of the drum 103 may have a thickness in a range of 3-10 mm. Additionally, the transparency of the material composition of the drum 103 can enable a liquid level within the drum 103 to be visible from its exterior. Further, the drum 103 can be sealed by placing the cover 106 on top of the first end 112 of the drum 103 and by fastening the cover 106 to the drum 103 with the ring clamp 109.
The drum 103 may also include additional structural features that can be used for a variety of purposes. As a non-limiting example, the drum 103 can be used in conjunction with liquid-based cleaning machinery, such as, for example, a pressure washer for industrial machinery or parts washing equipment. The drum 103 may comprise a first recessed platform 118, a second recessed platform 121, a first recessed port 124, a second recessed port 127, and liquid indicators 130.
The first recessed platform 118 can have a recessed area that extends inward toward an interior of the drum 103. The first recessed platform 118 can function as a handle for an operator and can also support another drum 103 in a nesting arrangement. The first recessed platform 118 has a first longitudinal length “L1.” The first recessed platform 118 may be closer to the first end 112 of the drum 103 than its second end 115.
The second recessed platform 121 can have a recessed area that extends inward toward an interior of the drum 103. The second recessed platform 121 can be used to connect with the first recessed platform 118 in a nested arrangement (
The first recessed port 124 can provide a side opening along the surface of the drum 103. The first recessed port 124 may be an upper recessed port that is closer to the first end 112 of the drum 103 than the second end 115. The first recessed port 124 can be configured as an inlet port or an outlet port for liquid to flow in or out of the drum 103. In some non-limiting examples, the first recessed port 124 can be coupled an insert 110 that can enable a fluid connector of a hose to attach the drum 103. As illustrated in
The second recessed port 127 can provide another side opening along the surface of the drum 103. The second recessed port 127 may be a lower recessed port that is closer to the second end 115 of the drum 103 than the first end 112. The second recessed port 127 can configured as an inlet port or an outlet port for liquid to flow in or out of the drum 103. In some non-limiting examples the recessed port 127 can be an outlet that connects to a pump and or strainer. In some examples, the second recessed port 127 can be located a certain distance from the bottom of the drum 103 to avoid a pump from picking up debris during a cleaning process.
As illustrated in
The liquid indicators 130 provide an indication of the quantity of liquid in the drum 103. The material composition and the thickness of the drum 103 can enable for the liquid level to be visible from the exterior of the drum 103. Because the liquid level can be visible through the surface of the drum 103, the liquid indicators 130 can provide an indication of the amount of liquid presently in the drum 103. Further, the drum 103 may also include a lip 133 that surrounds the first end 112 of the drum 103, as shown in
The inserts 110 can be attached to the recessed ports 124,127 of the drum 103. The inserts 110 can be used to seal the side opening of the recessed ports 124,127. Additionally, the inserts 110 can provide mechanical fastening components for attaching fluid connectors to the drum 103. In some embodiments, the inserts 110 may be omitted from the drum assembly 100. In other example scenarios, the inserts 110 may be attached to the drum 103 via a molding process. Multiple drums 103 can form a nested arrangement with or without the inserts 110 attached to the drums 103. The nestability of the drums 103 conserves space for multiple drums 103 placed in storage or transported to another location. Subsequently, the inserts 110 and associated components of a fluid connector can installed for use with a cleaning system.
The cover 106 can be used to seal the first end 112 of the drum 103 to prevent its contents from spilling out as the drum 103 is transported to another location. A portion of the cover 106 can be positioned adjacent to the lip 133 of the drum 103 or substantially near the lip 133 of the drum 103. The ring clamp 109 can be an annular clamp that has a clamp fastener 137. The ring clamp 109 can be used to fasten the cover 106 to the drum 103. Particularly, in some embodiments, the ring clamp 109 can physically secure or restrain a portion of the cover 106 against a portion of the lip 133. The clamp fastener 137 can open and close in order to expand and contract a diameter of the ring clamp 109.

In some examples, the raised flange perimeter 308 can be visible from the exterior of the drum, and the lowered flange perimeter 307 can be positioned against a perimeter of the first recessed port 124 or the second recessed port 127 of the drum 103. The attachment between the flange 303 and the perimeter of the first recessed port 124 or the second recessed port 127 of the drum 103 may be performed by a molding technique, such as injection molding, blow molding, or other suitable molding techniques. The inserts 110 form a fluid-tight seal at the first recessed port 124 and/or the second recessed port 127. The inner ring 306 extends a first length “L1” from the exterior side 304 of the flange 303, and extends a second length “L2” from the interior side 305 of the flange 303. The inner ring 306 can includes one or more inner threads 309 for coupling to a fluid connector.

Additionally,
Next, a general description of the operation of the various components of the drum assembly 100 is provided. To begin, the various embodiments allow for multiple drums 103 to be positioned in a nested arrangement 200 (
In one exemplary scenario, multiple drums 103 may need to be transported to another location or placed in storage. To conserve space, a nested arrangement 200 of the drums 103 may be implemented. As a non-limiting example, the second end 115 of a second drum 103b (
A gasket 612 is positioned between the flange 609 and the insert 110b. The gasket 612 can be used to fill in spaces between components and to help with seal area for fluid leaks. The gasket 612 can be comprised of rubber, EPDM, Silicone, or some other suitable flexible material that is chemically resistant. In the non-limiting example of
Further, the recessed bung adapter 603 has a threaded connection with the inner threads 309 of the insert 110, and the fluid connector 606 is coupled to a recessed opening 615 of the recessed bung adapter 603. The fluid connector 606 can have a threaded engagement with the recessed opening 615. As a reference, reference 618 represents a length of the recessed bung adapter 603 that extends beyond the insert 110b and into the interior of the drum 103.

With reference to
As illustrated, the recessed bung adapter 603 comprises a first cylinder 701 that extends to a second cylinder 702 with a smaller diameter. It should be noted that the recessed bung adapter 603 may have other shapes, such as a conical shape, a concave shape, or other suitable shapes. The flange 609 extends from the first cylinder 701. The recessed bung adapter 603 has an exterior opening 703 for the first cylinder 701 on one end and a recessed opening 615 for the second cylinder 702. The recessed bung adapter 603 comprises exterior threads 706 on its exterior surface. The exterior threads 706 can be used to form a threaded engagement with the interior threads 309 (

Next, another description of the operation of the various components of the drum assembly 100 is provided. In another exemplary scenario, the drum 103 can be assembled for use with various liquid-based cleaning machinery. In one exemplary assembly configuration, the first insert 110a can be coupled to the first recessed port 124 and the second insert 110b can coupled to the second recessed port 127. In some examples, the inserts 110 may be molded or welded into the first recessed port 124 and the second recessed port 127. The inserts 110 can seal a perimeter of the first recessed port 124 and the second recessed port 127 as liquid passes through the first recessed port 124 and the second recessed port 127. Then, the recessed bung adapters 603 (
As a non-limiting example, the various embodiments of the drum 103 can be coupled to an industrial pressure washer for degreasing mechanical components. In this example, the drum 103 has been assembled with the inserts 110 and hoses are attached to the first recessed port 124 and the second recessed port 127. The drum 103 may be filled with a cleaning solution that contains harmful chemical compounds to an operator. The cleaning solution can be pumped out of the second recessed port 127 and to a pressure sprayer configured to removing oil, grease, and other debris. Drainage from a wash bin for the industrial pressure washer can be funneled back to the first end 112 of the drum 103. Overtime, oil and other chemical residue substances may build up within the liquid in the drum 103. The second hose attached to the second recessed port 124 can be used for draining the oil and other chemical residue substances from the drum 103.
In another exemplary scenario, the drum 103 may need to be transported filled with liquid after being used with the industrial pressure washer. In some scenarios, the cleaning solution in the drum 103 may be thoroughly contaminated with oil and other residues after a period of time of cleaning one or more parts. At this point, the drum 103 can be configured to safely transport the harmful mixture. For example, the cover 106 can be placed over the first end 112 of the drum 103. The cover 106 can be positioned such that the lowered rim 155 is adjacent to the lip 133 of the drum 103. Then, the clamp fastener 137 can be manipulated to an open position in order to expand a diameter of the ring clamp 109. The ring clamp 109 can be positioned around the first end 112 of the drum 103, such that the lip 133 and the lowered rim 155 of the cover 106 are positioned within the annular slot 403 of the ring clamp 109. The clamp fastener 137 can be manipulated to a close open, which contracts the diameter of the ring clamp 109. By reducing the diameter, the ring clamp 109 can be tightened around the lip 133 of the drum 103 and the lowered rim 155 of the cover 106. Thus, the ring clamp 109 fastens the lowered rim 155 to the lip 133 of the drum. Also, the hose connectors 903 and their attached hoses may be detached from the fluid connectors 606 attached to the drum 103. Accordingly, the drum 103 with a fastened cover 109 can be safely transported to another location containing harmful chemical compounds.
