Description

[Technical Field]

[0001] The present invention relates to a jet assembly and jet system for fluid disbursement to a filtration screen. More particularly, the present invention relates to an asymmetric rotary jet nozzle assembly and a dewatering or filtration system that uses the asymmetric rotary jet nozzle assembly to jet fluid for cleaning and scouring a filtration or dewatering screen.

[0002] (Priority Claim) This application claims priority to U.S. Provisional Patent Application No. 63 / 421,053, filed October 31, 2022, the entire contents of which are incorporated by reference. [Background technology]

[0003] Many applications require systems configured to spray fluid outward from multiple nozzles onto surfaces requiring cleaning or scrubbing. Examples include dishwashers, slurry screens located in food processing plants, metal and mineral processing, and municipal or industrial waste disposal. Typically, cleaning processes are performed using automated systems configured to spray fluid automatically without the need for human intervention. Alternatively, cleaning processes are performed by one or more operators who physically manipulate a fluid spray system, such as a hose that is manually deployed as needed.

[0004] For automated jetting systems, several nozzles are typically arranged symmetrically around the axis of rotation, as shown in the conventional jetting system of Figures 1A-1C. In this configuration, each nozzle is paired with at least one other nozzle and has the same circular rotational path around the axis of rotation of the system. Other pairs of nozzles are arranged on different circular rotational paths, with each pair on its own path. This creates several circular paths along which the nozzle pairs rotate and then jet fluid onto the surface. Additionally, the even distribution of nozzle pairs balances the reactive forces that arise when the system operates.

[0005] One of the main drawbacks of using such a symmetrical nozzle configuration is that gaps that do not receive fluid can exist between each of the circular rotational paths, for example, when the surface being sprayed is close to the spray system or when the nozzles of the spray system have a narrow spray pattern. This typically results in some uncleaned areas on the surface being sprayed, necessitating manual operation of a separate fluid spray system to spray the remaining areas. Furthermore, symmetrical configurations typically use more nozzles than are actually needed to clean a particular surface, resulting in significant fluid waste. The introduction of excess fluid can be particularly disadvantageous in dewatering applications. Therefore, there is a need for a spray system that corrects the inefficiencies typically found in conventional symmetrical spray systems. Summary of the Invention [Problem to be solved by the invention]

[0006] In particular, the present disclosure provides a solution to the problem of nozzle overutilization and resulting fluid overutilization typically found in previously utilized symmetrical jetting systems. Specifically, embodiments of the present disclosure provide the same level of jetting coverage as conventional systems with fewer nozzles, or better jetting coverage with the same number of nozzles. [Means for solving the problem]

[0007] In an embodiment of the present invention, the asymmetric rotary spray nozzle system may be positioned adjacent to a filtering screen, such as a dewatering panel or a sieve panel.

[0014] Detailed Description of the Drawings 1A, 1B, and 1C, a conventional symmetrical rotary spray nozzle assembly in the prior art generally includes a plurality of arm combinations, each including two arms of equal length, each connected to a central hub that defines a central rotation axis for the symmetrical rotary spray nozzle assembly. Each arm generally includes a connector piece and a nozzle attached to the distal end of the arm, with the nozzles all facing the same fluid discharge ends and optionally angled to create rotation.

[0015] A key feature of conventional symmetrical rotary spray nozzle assemblies is that they are composed of various pairs of arms, each with equal or unequal lengths, rather than individual arms of different lengths. This creates circular paths around a central axis of rotation, and the arm pairs rotate along these paths, spraying fluid outward onto a surface. The primary drawback of such an arrangement is that gaps exist between each circular path that the fluid does not reach, leaving unsprayed areas on the surface to be sprayed (assuming the surface to be sprayed is close to the spray system or the spray system nozzles have a narrow spray pattern). Additionally, because each arm of each arm pair contains a similarly spaced nozzle assembly, such that each circular path is covered by two nozzle assemblies, excessive fluid may be sprayed into the same circular path.

[0016] 2A, 2B, and 2C, an asymmetric rotary spray nozzle assembly 110 according to an embodiment of the present invention generally includes an arm 112, a plurality of fluid dispensing nozzles 114, and a central hub 116. The asymmetric rotary spray nozzle assembly 110 is designed to be inherently balanced without the need for counterweights in the arm 112, and can achieve the same spray range as a conventional symmetric rotary spray nozzle assembly with fewer nozzles, or a wider spray range with the same number of nozzles as a symmetric rotary spray nozzle assembly.

[0017] The arm 112 has an elongated cylindrical geometry, such as a length of conventional tubing or pipe, although other geometries are contemplated. The total length of the arm 112 will vary depending on the particular injection application for which the arm 112 is used, but lengths of 12 inches to 48 inches are contemplated, but are not limited to such. Similarly, the cross-sectional diameter of the arm 112 will vary depending on the particular injection application, but cross-sectional diameters of 0.5 inches to 3 inches are contemplated, but are not limited to such. The arm 112 essentially has two arm segments 112a, 112b, each defined on opposite sides of a central hub 116. The arm 112 is generally fabricated from a fluid-compatible material, such as metal, e.g., stainless steel or aluminum, polymeric material, e.g., PVC, ceramic, and other composite materials.

[0018] The plurality of fluid dispensing nozzles 114 are removably connectable to the arm 112 and are positioned generally toward the filtration or dewatering panel 150. In one embodiment, each of the plurality of fluid dispensing nozzles 114 can be positioned to spray in the same direction or plane. In another embodiment, the fluid dispensing nozzles 114 can be positioned in different directions (i.e., in different planes). The plurality of fluid dispensing nozzles 114 can be positioned along a common centerline extending from the top to the bottom of the arm 112, or can be positioned at different radial locations along the arm 112 to accommodate different spray patterns. Positioning some or all of the fluid dispensing nozzles 114 at spray angles relative to the common centerline allows the arm 112 to rotate during operation. Preferably, the fluid dispensing nozzles 114 have spray nozzles with a fan spray pattern defined by a spray angle between 20° and 60°, more preferably between 30° and 40°. Alternatively, the fluid dispensing nozzle 114 may have jet nozzles defining other jet patterns, such as cone and jet, and combinations thereof.

[0019] The central hub 116 is configured to mount the asymmetric rotary spray nozzle assembly to a surface when a jet is generated. The central hub 116 typically includes a sealed bearing assembly (not shown) that allows the arms 112 to rotate about the central hub 116. Additionally, the central hub 116 may include a fluid connection that allows the asymmetric rotary spray nozzle assembly 110 to be fluidly connected to an available source of fluid, which ultimately is jetted from the fluid dispensing nozzle 114. The connection system 116 may be directly connected to a central arm opening (not shown) to establish a fluid connection between the fluid source and the interior of the arm 112 to supply the fluid dispensing nozzle 114. As shown, the fluid jet from the fluid dispensing nozzle 114 provides a driving force that drives the arm 112 to rotate about the central hub 116. In other embodiments, a motor may be attached to the central hub 116 to rotate the arm 112 at a desired speed.

[0020] 3, the filtration or dewatering system 100 may include a filtration or dewatering panel 150 and an asymmetric rotary jet nozzle assembly 110 positioned toward a rear surface 152 of the filtration or dewatering panel 150. Typically, the asymmetric rotary jet nozzle assembly 110 is positioned approximately two inches away from the filtration or dewatering panel 150, although different distances are contemplated based on the needs and size limitations of a particular jetting application. While the asymmetric rotary jet nozzle assembly 110 is shown spraying toward the rear surface of the filtration or dewatering panel 150, it will be understood that it may be advantageous in certain applications to reverse the orientation of the asymmetric rotary jet nozzle assembly 110 to spray toward a front surface 154 of the filtration or dewatering panel 150.

[0021] The filtration or dewatering panel 150 typically includes multiple screening elements attached to an underlying support structure. The filtration or dewatering panel 150 typically defines an upper screening surface extending between an upper end and a lower end. The upper screening surface typically defines a number of openings or "slots" through which slurry passes and is dewatered. The upper and lower ends may have attachments, such as angled bars or flanges, to connect and hold the filtration or dewatering panel 150 together during operation. In some embodiments, the screen surface may include what is conventionally referred to as a shaped-wire or Vee-wire screen surface. During operation, slurry is typically introduced at the upper end of the filtration or dewatering panel 150 and flows by gravity toward the lower end. As the slurry flows down the filtration or dewatering panel 150 and onto the upper screening surface, the fluid and any accompanying particles smaller than the openings / slots pass through the upper screening surface, while particles larger than the openings / slots travel along the upper screening surface and are collected at the bottom of the sieve panel for further processing. The asymmetric rotary jet nozzle assembly 110 is typically configured to jet on demand, typically for a few seconds or minutes every four to eight hours, depending on the application and load, to loosen, remove, and clean particles accumulated on the filtration or dewatering panel 150. As noted above, in some embodiments of the present invention, the asymmetric rotary jet nozzle assembly 110 may be configured to jet onto the front surface 154 of the filtration or dewatering panel 150 instead of the rear surface.

[0022] 4A, 4B, and 4C, the asymmetric rotary spray nozzle assembly 210 generally includes a central hub 216, a plurality of arm segments 212, a plurality of nozzle connectors 218, one or more fluid dispensing nozzles 214, and, optionally, a counterweight 222 attached to at least one of the arm segments 212. The central hub 216 generally defines a central axis of rotation for the asymmetric rotary spray nozzle assembly 210. Advantages of the asymmetric rotary spray nozzle assembly 210 over conventional assemblies include being driven by the force generated during spraying without a motor (although embodiments including a separate motor are also contemplated), and providing the same spray range with fewer nozzles or a wider spray range with the same number of nozzles.

[0023] The central hub 216 generally includes a main segment, typically having an elongated cylindrical geometry with upper, lower, and side surfaces between the upper and lower surfaces, and a connecting segment extruded from the lower surface of the main segment for attachment to a rotating assembly (not shown). The connecting segment generally has a cylindrical shape similar in design to the main segment, as most clearly shown in FIG. 4C, but may vary in size depending on design requirements. Other geometric shapes for the central hub 216 are contemplated, including rectangular, triangular, and spherical. The central hub 216 is generally fabricated from a metallic material, such as stainless steel or aluminum, although polymers, ceramics, and composite materials are also contemplated.

[0024] The arm segments 212 generally have a hollow, elongated cylindrical geometry, such as a conventional pipe or tube, although other geometries are contemplated. Each arm segment 212 of the arm segments 212 is coupled to a side surface of a central hub 216 and is typically detachable to allow the number of arm segments 212 to be varied or, alternatively, the number of arm segments 212 is fixed for a particular asymmetric rotary spray nozzle assembly 210. The arm segments 212 are typically fabricated from a metallic material, such as stainless steel or aluminum, although polymers, ceramics, and composite materials are also contemplated. In some embodiments, the arm segments 212 are positioned on opposite sides of the central hub 216 such that the opposing arm segments 212 are functionally similar and operate in a manner similar to the arm 112 shown and described above.

[0025] The nozzle connector 218 can be fixedly or removably coupled to the end of each arm segment 212. The nozzle connector 218 serves as an intermediate connection point between the arm segment 212 and each fluid dispensing nozzle 214, allowing fluid to flow uninterrupted through each arm segment 212 and exit through each fluid dispensing nozzle 214. The nozzle connector 218 generally has a cubical shape connected to an elongated cylindrical segment as a single unitary member, the cylindrical segment having an opening through the hollow center of each arm segment 212 that is large enough so that the outer surface of each arm segment 212 coincides with the inner surface of the opening. The nozzle connector 218 is typically fabricated from a metallic material such as stainless steel or aluminum, although polymers, ceramics, and composite materials are also contemplated.

[0026] One or more fluid dispensing nozzles 214 are fixedly connectable to each nozzle connector 218 and are typically oriented relative to the filtration or dewatering panel 250 or other target surface, although other orientations are contemplated. In embodiments, each of the one or more fluid dispensing nozzles 214 may be oriented toward the same direction or surface. Alternatively, the fluid dispensing nozzles 214 may be oriented in different directions (i.e., on different surfaces) to accommodate spraying of various filtration or dewatering panels 250 or to accommodate differences in the filtration or dewatering panels 250. The one or more fluid dispensing nozzles 214 may be positioned along a common centerline extending from the top to the bottom of each arm segment 212, or may be positioned at radial locations along each arm segment 212 to accommodate different spray patterns or different target areas.

[0027] The fluid distribution nozzle(s) 214 may comprise a fan nozzle defining a fan-shaped spray pattern with a spray angle between 20° and 60°, preferably between 30° and 40°. Alternatively, the fluid distribution nozzle 214 may comprise a spray nozzle defining other spray patterns, such as conical and linear, and combinations thereof.

[0028] One or more fluid dispensing nozzles 214 are fixedly connectable to at least one of the arm segments 212 and can be positioned in a combination of different symmetrical and asymmetrical positions suitable for a particular jetting application. In an embodiment, the fluid dispensing nozzles 214 are releasably connectable to either the upper or lower surface of the central hub 216 in a direction toward or away from the one or more fluid dispensing nozzles 214 connectable with each nozzle connector 218.

[0029] In embodiments, a counterweight 222 may be attached to one or more arm segments 212 to balance the reactive forces resulting from the asymmetric rotary spray nozzle assembly 210. The counterweight 222 generally has an elongated cylindrical geometry with an opening extending through its central portion, the opening being large enough so that the outer surface of the arm segment 212 coincides with the inner surface of the opening. Other geometries for the counterweight 222 suitable for attachment to one or more arm segments 212 are contemplated and may be more practical depending on the particular configuration in which the asymmetric rotary spray nozzle assembly 210 is used. The counterweight 222 may vary in mass depending on the particular spray application and the structural requirements of the asymmetric rotary spray nozzle assembly 210. For example, multiple counterweights 222, each with a different mass, may be used to balance the reactive forces resulting from the asymmetric rotary spray nozzle assembly 210. The counterweight 222 is typically fabricated from a metallic material such as stainless steel or aluminum, although polymers, ceramics, and composite materials are also contemplated. In an embodiment, the counterweight 222 and nozzle connector 218 may be manufactured as a single unitary member for simplicity.

[0030] Referring to the filtration or dewatering panel 250, during operation, fluid enters the central hub 216 from a fluid source and passes through each arm segment 212 and the nozzle connectors 218 of the asymmetric rotary jet nozzle assembly 210. The fluid flow rate may be the same or different for each arm segment 212. The fluid then flows out one or more fluid distribution nozzles 214 and is sprayed onto the filtration or dewatering panel 250. Depending on the application, the asymmetric rotary jet nozzle assembly 210 can be operated continuously, although in many applications the asymmetric rotary jet nozzle assembly 210 will be operated intermittently, for example, for a few seconds or minutes every 4 to 8 hours, to avoid introducing too much fluid into the process.

[0031] 5, an asymmetric rotary spray nozzle assembly system 200 may include a filtration or dewatering panel 250 and an asymmetric rotary spray nozzle assembly 210 having, for example, six arm segments 212 and positioned toward the rear surface 152 of the filtration or dewatering panel 250 as shown and described herein. While operation of the asymmetric rotary spray nozzle assembly 210 with the filtration or dewatering panel 250 may be continuous, in many applications operation is intermittent, for example, for a few seconds or minutes every 4 to 8 hours, to avoid introducing excessive fluid into the process. In other embodiments, the asymmetric rotary spray nozzle assembly 210 may be positioned to face the front surface 154 of the filtration or dewatering panel 250 instead of the rear surface 152.

[0032] 6A, 6B, and 6C, an asymmetric rotary spray nozzle assembly 310 according to another embodiment of the present invention is shown. The asymmetric rotary spray nozzle assembly 310 is structurally similar to the asymmetric rotary spray nozzle assembly 210, except that it has three arm segments 312 instead of six. For simplicity, like-numbered elements of the asymmetric rotary spray nozzle assembly 310 are considered identical to the corresponding elements of the asymmetric rotary spray nozzle assembly 210 (e.g., arm segment 312 is equivalent to arm segment 212, nozzle connector 318 is equivalent to nozzle connector 218, and so on). As with the previously described embodiments, the asymmetric rotary spray nozzle assembly 310 may utilize a driving force to rotate the arm segments 312 about a central hub 316 provided by a jet from a fluid dispensing nozzle 314, although in some embodiments, a motor may be utilized to provide rotation of the asymmetric rotary spray nozzle assembly 310 at a desired speed.

[0033] 7, an asymmetric rotary spray nozzle assembly system 300 may include a filtration or dewatering panel 350 and an asymmetric rotary spray nozzle assembly 310 having three arm segments 312 and positioned toward the rear surface 152 of the filtration or dewatering panel 350 as shown and described herein. Operation of the asymmetric rotary spray nozzle assembly 310 with the filtration or dewatering panel 350 may be continuous, although in many applications operation is intermittent, for example, for a few seconds or minutes every 4 to 8 hours, to avoid introducing excessive fluid into the process. In other embodiments, the asymmetric rotary spray nozzle assembly 310 may be positioned to face the front surface 154 of the filtration or dewatering panel 350 instead of the rear surface 152.

[0034] In operation, the fluid dispensing nozzles 114, 214, 314 used with the asymmetric rotary spray nozzle assemblies 110, 210, 310 may operate with spray pressures of 1,000 to 2,000 psi. In certain applications, such as continuous spray applications or spray applications for longer periods of time (i.e., more than a few minutes at a time), lower spray pressures may be beneficial.

[0035] As shown in FIG. 8, an asymmetric rotary spray nozzle assembly 410 according to another embodiment of the present invention is illustrated. The asymmetric rotary spray nozzle assembly 410 may include an arm 412, a plurality of fluid dispensing nozzles 414, and a central hub 416. The arm 412 is defined by a pair of arm segments 412a, 412b located on opposite sides of the central hub 416. Each of the arm segments 412a, 412b is further defined by an inner segment 413a and an outer segment 413b, with inner and outer being referred to relative to their proximity to the central hub 416. The inner segment 413a and outer segment 413b are fluidly connected at a bend 415 such that each of the arm segments 412a, 412b defines a non-linear arm segment 417a, 417b. Alternatively, the non-linear arm segments 417a, 417b may have a curved configuration. 8, multiple fluid dispensing nozzles 414 are spaced at different lengths from a central hub 416. By spacing the fluid dispensing nozzles 414 at appropriate distances, the asymmetric arrangement provides an increased spray range while essentially balancing the asymmetric rotary spray nozzle assembly 410. Alternatively, one or more counterweights may be attached to one or both ends of the arm segments 412a, 412b to balance the asymmetric rotary spray assembly 410.

[0036] 9, the non-linear arm segments 417a, 417b of the asymmetric rotary spray nozzle assembly 410 may be positioned to spray against the inner curved surface portion of the filtration or dewatering panel 150, providing greater functionality as part of the filtration or dewatering system 400. As shown, the asymmetric rotary spray nozzle assembly 410 is attached to the filtration or dewatering panel 150 to spray the front surface 154. Alternatively, the asymmetric rotary spray nozzle assembly 410 is attached to the filtration or dewatering panel 150 to spray the rear surface 152. The number and spacing of the fluid dispensing nozzles 414 on the non-linear arm segments 417a, 417b is specifically selected and spaced depending on the application.

[0037] Referring now to FIG. 10 , a method 500 of controlled fluid delivery to a filtration or dewatering panel 250 is outlined. In step 502, an asymmetric rotary jet nozzle assembly 210 is configured to distribute fluid through one or more fluid distribution nozzles 214. In step 504, the asymmetric rotary jet nozzle assembly 210 is positioned adjacent to the filtration or dewatering panel 250. In step 504, the asymmetric rotary jet nozzle assembly 210 may be positioned adjacent to the rear surface of the filtration or dewatering panel 250, or alternatively, the front surface. In step 506, fluid is directed from the asymmetric rotary jet nozzle assembly 210 and sprayed against the exterior filtration or dewatering panel 250. In step 506, the process may be continuous or intermittent, depending on the process. In step 508, the fluid is removed from the filtration or dewatering panel 250 through a set of slots defined in the sieve panel 250.
