CHEMICAL JUG WASHER AND DISPOSAL ASSEMBLY

Abstract

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 floor of the chamber has irregular surfaces to assist in deforming the jug during puncturing and outflow of contaminated fluid. 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 cleaned and punctured jug.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] With reference to the attached illustrations, the present invention teaches a combination cleaning and disposal assembly, see generally at 10 in FIG. 1, for safely cleaning and rendering unusable a jug containing a hazardous chemical residue. The assembly incorporates a body, such as without limitation a frame including welded aluminum supports including in plan cutaway vertical extending supports 12, 14, et seq. and interconnecting horizontally spaced supports 16, 18, et seq. As shown, the body exhibits a generally rectangular configuration if viewed in three dimension however can further have any suitable shape.

[0024] As further shown, the body (or frame) includes a horizontally extending grate or other support 20 which is located a distance below the horizontal support surface 18, the space defined therebetween being a jug receiving chamber 22 within which is inserted a residue contaminated jug 2. A first loading tray 24 provides for introduction of a succeeding contaminated jug 2 into the receiving chamber 22, with a second opposite extending loading or unloading tray 26 providing for removal of a preceding and cleaned/destroyed jug 2 which is safe for disposal or recycling.

[0025] Without limitation, the trays 24/26 can be utilized solely to place or remove jugs to and from the receiving chamber 22 or can be additionally used to support the jugs during pre or post rinsing thereof, such as in order to remove addition contaminants residing on the exterior of the jugs. The jug 2 depicted in FIGS. 2-3 is shown with a rectangular cross section, such defining a 2.5 gallon reservoir, however it is understood that these can exhibit any suitable shape or volumetric holding capacity.

[0026] A jug piercing manifold 26 is positioned above the jug 2 placed within the receiving chamber 22 and includes any number of hollowed and fluid communicating spikes, see further at 28, 30, 32, etc., in FIGS. 2-3, for successively impaling and pressure washing the jug 2 or other container. A high pressure pump 34 draws fresh water or other cleaning fluid from a first proximately located tank or reservoir 36, via an inlet line 38. An outlet line 38 extends to the manifold 26 and to the impaling spikes 28, 30, 32, et seq. forming the displacing manifold.

[0027] As further best shown in each of the intermediate piercing view of FIG. 2 and the fully pierced view of FIG. 3, the pressurized fluid flows across the contaminated interior of the jug 2 and then out through a bottom of the container (typically laying on its side) which has been completely through punctured by pointed tips, further at 40, 42, 44 et seq. of the spikes 28, 30, 32. As further previously described, the floor (again at 20) of the jug receiving chamber is exhibited by a spaced grid or other apertured support surface which allows the tips 40, 42, 44 et seq. of the spikes 28, 30, 32, et seq, to pass unimpeded through the floor support to facilitate through drainage of the contaminated fluid, see at 4 in FIG. 3.

[0028] The contaminated fluid subsequently drains, via an underneath located collection pan 46 and connecting drain 48 into a second proximately located chemical rinse and storage tank 50 for secure disposal. As further shown in FIG. 1, both the first fresh water tank 36 and the second rinse tank 50 include top screw cap ports, at 52 and 54, respectively, these providing respectively for refill of emptying of the tanks. A sump pump 56 is also incorporated into the frame in fluid communication with the contaminated rinse tank, see line 58, for controlled drain disposal of the collected fluid.

[0029] An on/off switch 60 is secured to a visible location of the frame and, via an associated power supply and wiring (not shown) is configured for reciprocatingly displacing in bi-directional linear motion the manifold 26 and spikes 28, 30, 32, et seq. into successive piercing and retracting motions relative to each successively loaded jug within the receiving chamber. To this end, the horizontal support 18 above the receiving chamber 22 in turn supports a fixed cylinder 62 associated with the bi-directional linear drive, a reciprocating shaft 64 projecting downwardly from the cylinder 62 and supporting at its end the manifold 26 and plurality spikes 28, 30, 32, et seq. in downwardly projecting fashion.

[0030] Although not shown, it is understood that the manifold 26 receiving the pressurized fluid via the internal fluid conveying network (see again pressurized fluid line 38) is in communication with a hollow interior of each projecting spike, and typically by the interior of the manifold having a channel network communicating fluid flow to a hollow top inlet location for each of the spikes 28, 30, 32, et seq., these in turn being internally hollowed with perforations there along (further individual pluralities of which are best shown at 66, 68, 70 et seq. for spikes 28, 30, 32. et. seq) and for issuing the pressurized fluid within at least an interior of the pierced container as depicted in each of FIGS. 2-3.

[0031] As further depicted in each of FIGS. 1 and 3, the second horizontal support 18 located below the (generally flattened and plate shape) manifold 26 and allows for a complete range of reciprocating (typically bi-directional vertical) motion of the manifold and spikes through the support 18, an underside surface of the support 18 being further understood to be employed so as to forcibly dislodge the container from the spikes during (upward) retraction of the spikes through the second support 18. Without limitation, it is understood that additional embodiments may contemplate an arrangement in which a repositioned and reconfigured manifold is displaced either sideways or upwardly, yet additional embodiments envisioning the manifold being fixed and the container and its associated support surface being bi-directionally displaced both toward and away from the manifold and spikes.

[0032] Additional features include at least one extending side of the sealed enclosure defining the jug receiving chamber further including a transparent window (see partial designation at 72 in each of FIGS. 2-3). In a specific non-limiting embodiment, the at least one window can further be provided as a multi-sided plexi glass enclosure surrounding the jug receiving chamber, with first and second doors (these further depicted in non-limiting fashion as slide-up doors 74 and 76 in FIG. 1) configured within associated enclosure defining panels and communicating with the first 24 and second 26 trays.

[0033] FIG. 4 is an illustration similar to FIG. 1 of the chemical jug washing and disposal assembly 100 according to a further embodiment which is largely identical to that shown in FIG. 1, with the exception that the grid style floor of the jug receiving chamber is redesigned at 102 to exhibit a planar outer perimeter 104 bounding an interior and irregular surface profile for facilitating puncturing and deformation of the jug 2 and to expedite flushing of the chemical residue from the jug interior by the fluid spray issuing spikes 28, 30, 32, et seq. with expedited drainage of the contaminated fluid through the lower located tray and outlet.

[0034] FIG. 7 is an illustration of the floor of the receiving chamber in the embodiment of FIGS. 4-6 and better shows the configuration of a plurality of individual drainage pockets, at 106, 108, 110, et seq., formed into the chamber floor 102 and associated with each of the descending spikes. As shown, the pockets each exhibiting recessed angled surfaces (by example shown by interconnected surfaces 112, 114, 116, et seq. for selected pocket 106) and for facilitating outflow and drainage of contaminated fluid resulting from spraying of pressurized fluid/water from the spikes within the interior of the jugs.

[0035] The contaminated fluid drains through the puncture locations in the jug initiated by the tips of the spikes, this action causing the jug to deform against the pockets to further expedite drainage (as shown in FIGS. 4 and 6). Apertures are defined centrally within the recessed pocket of each of the non-planar angled surfaces, these defined by interior rim edges 118, 120, 122, et seq. for pockets 106, 108, 110, et seq. The diameter of the inner perimeter edge defining apertures is such that the tips 40, 42, 44 of the spikes (an optionally the full diameter of each spike) can project a distance beyond the floor 102 for assisting in quick cleaning and draining of the fluid from the jug compartment.

[0036] FIG. 5 is an enlarged plan view of the receiving chamber of FIG. 4 and illustrating the spike manifold in an intermediate puncturing position, with FIG. 6 providing a succeeding illustration to FIG. 5 showing the spikes in a fully descended and jug impaling condition in which the outflow drainage of contaminated fluid is shown descending through the irregular floor profile associated with the receiving chamber prior to draining through the underneath located tray and collecting within the rinse tank. The diameter of the floor apertures 118, 120, 122, et seq. is again in alignment with the tips of the spikes to ensure that the jugs 2 are each fully impaled and deformed as shown in FIG. 6 and further that the result is that the contaminated interior is adequately cleaned for normal disposal, with the jug being ensured not to be reusable. The tips of the spikes are further understood to travel any intermediate distance between the floor 102 and the underneath located receiving pan or tray 46, the design of which is intended to prevent puncturing or damage to the tray.

[0037] Without limitation, the recessed or other irregular configuration of the floor of the jug receiving chamber can be further modified from that shown so as to include any other envisioned non-planar configuration (including other than individual receiving pockets) which assists in deforming the jug, such as at the point of the spike tips puncturing through the jug. This can include the formation of concave or angled surfaces from the pocket version shown to one which extends the entire length or width of the floor.

[0038] The diameter and profile of the individual apertures in the floor is again further capable of being varied from that shown to facilitate flow through drainage of the contaminated fluid once washed out through the jug interior. This can include the apertures having a non-circular pattern to enhance flow through once the spike tips project therethrough (again FIG. 6).

[0039] Without limitation, the floor 102 (such as including a rigid metal or other suitable durable material) can be provided in combination the vertical supports 20 located under the floor grid in the variant of FIGS. 1-3. It is envisioned that the floor 102 is adequately durable to be provided without any underneath reinforcement beyond that associated with the anchoring of the floor to the inner facing rim edges of the jug receiving compartment 22.

[0040] Having described our invention, other and additional preferred embodiments will become apparent to those skilled in the art to which it pertains, and without deviating from the scope of the appended claims. This can include reconfiguring the frame and manifold such that the manifold can be caused to be fixed (thus dispensing with the need of a linear reciprocating drive), such instead being integrated into an elevator type arrangement associated with the floor grate or other support of the contaminated jug receiving chamber, and so that it can be caused to be vertically displaced into each of a first (elevating) contact with the downwardly arrayed spikes, following which the subsequent descending of the floor grate or support ensures that the jug is extracted from the spikes (this further accomplished by otherwise temporarily affixing or securing the jug to the floor grate in some secure manner.

[0041] Other variants can be provided without either or both of the first supply and second contaminated rinse collection tanks. This can include a city water inlet being directly communicated to the high pressure water pump and/or an outlet extending from the drain and to some other secure contaminated collection sink or reservoir (either with or without a sump pump as shown).
