The present invention relates generally to container cleaning and washing techniques. More particularly, the present invention discloses a washer assembly for cleaning used chemical jugs or containers of any size, the assembly including a lid accessible and water-tight interior compartment for inserting and positioning the empty container in an inverted manner over an upright supported spray tube or rod. Each of pressurized fluid supply and drain connections are provided for cleaning the jug interior prior to removal and reuse or disposal of the jug or container.
The prior art is documented with numerous examples of jug cleaning and washing assemblies. One common practice is to insert a conventional hose into the jug interior and prior to dumping the contents into the spray tank.
An example of a chemical jug washer and disposal assembly is disclosed in US 2016/0303624 and related U.S. Pat. No. 10,603,699, to Hitchens, which teaches a combination cleaning and disposal assembly for safely cleaning and rendering unusable a jug containing a hazardous chemical residue. A body supports a receiving chamber for receiving the jug. A manifold is supported by the body and has a plurality of spikes arrayed toward the jug. A pressurized fluid source is communicated to the manifold such that, upon an inter-displacement occurs between the manifold and the container, the spikes are caused to pierce the container, the pressurized fluid being caused to issue from the spikes to clean an interior of the container. A drain is located underneath the jug receiving chamber which collects and segregates the fluid contaminated with the chemical residue for securing disposal concurrent with removing and disposing of the now-cleaned and punctured jug.
The present invention discloses a washer assembly for cleaning used chemical containers, such as prior to eventual disposal however also having the option to reuse the jug. The assembly has a sealed chamber with a hingedly attached lid. A spray tube is supported in upright extending fashion upon a pan shaped basin of the sealed chamber. A fresh fluid inlet feeds pressurized fluid flow to the spray tube for spraying an inside of the chemical container placed over the tube, such that the fluid collects upon the basin. A drain is incorporated into the basin for removing contaminated fluid from the chamber.
The fluid can also include water with or without a chemical additive. A rinse pump feeds the pressurized fluid flow through an inlet line connecting to the spray tube.
A drain pump is incorporated into the drain for withdrawing the fluid. The spray tube further includes a plurality of jet nozzles for redirecting the pressurized fluid evenly across an interior area of the container.
A fresh fluid reservoir connects to the fresh fluid inlet, with a contaminated fluid reservoir connecting to the drain. A common fluid reservoir connects to the drain via an intermediately located filtration system, the common reservoir having an outlet connecting to the fluid inlet.
A drain pump is incorporated into an inlet to the common reservoir, a rinse pump incorporated into the common reservoir outlet. An aperture platform is positioned above the drain for supporting an inverted top of the container positioned over the spray tube.
Reference will now be made to the attached drawings, when read in combination with the following detailed description, wherein like reference numerals refer to like parts throughout the several views, and in which:
With reference to the attached illustrations, the present invention discloses a washer assembly for cleaning used chemical jugs or containers of any size, the assembly including a lid accessible and water-tight interior compartment for inserting and positioning the empty container in an inverted manner over an upright supported spray tube or rod. Each of pressurized fluid supply and drain connections are provided for cleaning the jug interior prior to removal and reuse or disposal of the same.
The washer assembly includes a body 12 defining a sealed inner chamber with a hingedly attached lid 14. The chamber can be constructed of any of a clear plexi-glass, other polycarbonate material, a metal or metal alloy including but not limited to aluminum. Upon rotating the lid 14 downwardly over the open top of the chamber, an interior enclosure of the chamber is sealed in order to be waterproof during subsequent operation.
A spray tube 16 is supported in upright extending fashion upon a pan shaped basin 19 within the sealed chamber 12. The spray tube 16 further exhibits a plurality of jet nozzles (also defined as slits) 18 for redirecting the pressurized fluid evenly across an interior area of the container 2 (and as further shown in
A fresh fluid inlet (or inlet line) 20 feeds pressurized fluid flow to the spray tube 16 for spraying an inside of the chemical container 2 placed over the tube 16 as referenced in either of
Without limitation, the fluid includes water with or without a chemical cleaning additive. In order to maintain pressurized fluid flow, a rinse pump 24 feeds the pressurized fluid flow through the inlet line 20 connecting to the upright affixed spray tube 16 (see further via a mounting nut 26 for upright affixing the tube within the enclosure.
A fresh fluid reservoir 28 is connected to the inlet line 20 and can include a removable cap 30 for ease of refilling and, if necessary, for mixing water with any desired chemical cleaning additive. Alternatively, the inlet 20 can connect directly to a separate pressurized fluid source such as a city water hooking, well water hookup or the like in which pressurized inlet fluid is provided without a separate inlet reservoir.
Upon washing the container and collecting the dirty/used fluid upon the pan shaped basin 19, the fluid is collected and drained via a drain pump 32. The dirty fluid can be connected to a dirty fluid reservoir 34, such also including a removable cap 36 for ease of emptying the reservoir. Alternatively, the dirty fluid reservoir can be substituted with a direct drain to any type of dirty water outlet. Also without limitation, the inlet 28 and outlet 34 reservoirs can either or both be incorporated into a housing containing the chamber or can be separately located.
An aperture platform 38 (not limited to a grill style grating, aperture plate or the like) is positioned above the drain for supporting an inverted top of the container 2 positioned over the spray tube 16. The sizing of the container 2 can again be varied up to any size, such as which will fit within the chamber interior 12.
