Abstract: An oscillating spray nozzle and related methods for providing spray patterns in a variety of oscillating patterns by driving movement of the nozzle with a progressing cavity displacement motor. By varying the design of the progressing cavity displacement motor, a variety of spray pattern geometries can be generated and a speed of the nozzle as it travels through the spray pattern geometries can be controlled. The oscillating spray nozzle can include a housing enclosing a progressing cavity motor that is operably connected to a spray nozzle. The progressing cavity motor includes a rotor member that is caused to rotate and oscillate within a stator member. The rotor member is operably linked to the spray nozzle, whereby the movement of the rotor member is communicated to the spray nozzle.

Abstract: A chemical dispensing system including a rack based system that can hold a plurality of chemical dispensing containers. The chemical dispensing containers can make use of concentrates or hyper concentrates of chemicals allowing smaller capacity containers. The rack based system can include a modular rack that is configurable to hold a desired number of containers. Using the modular rack, the containers can be easily ganged together to increase capacity or build in redundancy for one or more of the chemicals through the configuration of a rack manifold constructed of individual manifold segments. Within the manifold, various flow paths can be linked or terminated between adjacent manifold segments and chemical containers.

Abstract: A system for controlling and monitoring the chemical usage in a car wash systems that form an aqueous cleaning solution by diluting a cleaning chemical concentrate in a process water stream to form. Level sensors are mounted to the bulk containers containing the chemical concentrate to measure and track the usage of the chemical concentrates. The usage data is collected and used to adjust flow rate controllers controlling the dilution of the concentrate into the process water stream. The system can be integrated into continuous processes where the aqueous cleaning solution is dispensed immediately after production and batch processes where the cleaning solution is stored temporarily before being dispensed onto a vehicle.

Abstract: A chemical delivery system that delivers concentrated liquid chemical using a non-liquid motive fluid to deliver the concentrated liquid chemical in an undiluted form to a point of use. The concentrated chemical is delivered by the motive fluid by way of the aggressive interaction of a high-pressure jet stream of motive fluid causing a nearly complete local vacuum such that the concentrated chemical is drawn under low pressure into a jet vortex to form a chemical dispersion. Forming the chemical dispersion by way of this venturi eduction process occurs in a substantially continuous real-time manner allowing for multiple methods of controlling the total amount of chemical delivered and the rate in which it is delivered to the application device.

Abstract: A chemical dispensing assembly having injector assemblies that combine a solvent stream with a concentrate stream within a Venturi injector assembly to produce a chemical solution outlet stream. Each injector assembly has an interchangeable metering assembly that limits the flow of concentrate into the Venturi injector assembly to change the resulting concentration of the concentrate within the solution outlet stream. The chemical dispensing assembly also has a keyed connector system that prevents the connection of the wrong concentrate container to the wrong injector assembly.

Abstract: A chemical delivery system capable of handling a variety of concentrated chemicals in such a manner as to reduce the amount of service required to maintain the system. The system should be able to accurately and consistently deliver an appropriate quantity of concentrated chemicals as needed by the application where the system is utilized. Additionally, the system is configured such that the system occupies as little space as necessary.

Abstract: An improved venturi-style eductor apparatus for dispensing chemicals into a motive fluid stream where an eductor body FIG. 3 is manufactured by molding a chemically inert polymer material FIG. 2 around and inside a metallic insert FIG. 1. Opposing ends of the metallic insert may be threaded, flanged, or machined for push-in connection to facilitate mating with a motive fluid source and a dispensing device. By manufacturing an eductor assembly using a single-piece metal insert over-molded with an inert polymer provides improved chemical resistance for aggressive applications and allows improvements in venturi geometry not achievable using traditional machined components. This apparatus reduces manufacturing cost over current state-of-the-art eductor assemblies by using a single molding step to create flow-path geometry in the eductor body while retaining mechanical strength with the metallic insert FIG. 1.

Abstract: Chemical dispensing systems and related methods for precision handling of fluids including water and bulk chemicals. Representative chemical dispensing system can include wall mounted dispensing panels or portable, frame mounted dispensing units. These chemical dispensing systems provide easy access to all required interfaces including water, chemical, air, electrical and solution. The wall mounted dispensing panel can include a molded routing panel having molded recesses for mounting and managing specific air, fluid and control modules. The portable, frame mounted dispensing unit can include an onboard pump assembly for pressurizing a motive fluid. The frame assembly can include one or more lifting handles and adjustable feet to allow for easy transportation and placement of the portable dispensing unit.

Abstract: Apparatus and related methods for continually measuring and dispensing precise amounts of bulk chemical in a car wash application. A gravimetric dispensing assembly can include a load cell and a syringe dosing pump that is suspended below the load cell such that an entire mass of the syringe dosing pump is communicated to the load cell. In this manner, the load cell can measure the actual mass of chemical being dispensed from the syringe dosing pump on a continuous basis without solely relying on the rated volumetric capacity of the syringe dosing pump. The syringe dosing pump can be driven by a stepper motor that can be pulsed as directed by a controller so as to maintain, increase or decrease an amount of bulk chemical being dispensed from the syringe dosing pump.

Abstract: A configurable rotary spray nozzle having lower manufacturing and maintenance costs through the use of an external shell providing strength and resistance to damage such that molded internal components can be utilized to provide the desired spray characteristics. The molded internal wet components can comprise molded polymeric structures that allow for the formation of complex flow geometries and structures that are either impossible or economically impractical to achieve with conventional tooling and machining operations. The use of an external shell provides for use of replacement kits to maintain or otherwise replace worn and/or damaged internal wet components while reusing the external housing. The use of the external shell also allows a user to customize and change spray performance of the configurable rotary spray nozzle by swapping internal wet components having selected flow geometries and characteristics so as to provide a desired spray performance.

Abstract: An expandable chemical delivery system sharing a common bulk fluid inlet and bulk fluid flow path to direct a bulk fluid through one or more selected chemical eductors. Each chemical eductor is slidably insertable into an eductor port on the manifold body such that rotation of the chemical eductor is not required for installation. After installation, the orientation of the chemical eductor can be rotatably adjusted so as to avoid interference with adjacent chemical eductors. Delivery of a bulk fluid to each chemical eductor is controlled via a corresponding valve assembly that selectively allows or blocks flow of the bulk fluid from the bulk fluid flow path to the corresponding chemical eductor. The manifold body can include a plurality of individual manifold bodies approximated with a coupling system to define the bulk fluid flow path. Alternatively, the manifold body can comprise a single fabricated body for high pressure operation.
