Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims benefit to provisional patent application Ser. No. 62/012,526, filed 16 Jun. 2014, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a pump for providing fluid and particulate; and more particularly relates to a diaphragm pump having a manifold assembly for pumping viscous fluid having solids and particulates.
2. Brief Description of Related Art
FIG. 1 shows a diaphragm pump having a pump manifold with spring-loaded or ‘umbrella’ valves, which is known in the art. In FIG. 1, the spring is arranged between upper and lower umbrella valves. Pump are also known in the art having fixed wiring. Shortcomings of the known diaphragm pump configurations may include one or more of the following:
a. Valve Types—Spring loaded and umbrella style valves are limited to pumping low viscosity and “debris free” fluids. Liquids with high viscosity and/or particulates cause priming and performance issues on existing valve types.

- i. Umbrella type valves—Consistent with that shown in FIG. 1, these umbrella type valves typically easily clog due to particulates in the fluid. When the umbrella type valves are clogged/fouled, they will not seal properly and this prevents the pump from priming and building pressure.
- ii. Spring loaded valves—Consistent with that shown in FIG. 1, the solids in the liquid being pumped typically become entangled in the spring mechanism and prevent the valve from opening and closing.

b. Pumps having fixed wiring do not have the flexibility to quick connect/disconnect for servicing. Typical pumps have fixed wiring extending from the motor. If the user requires a connector that must be attached to the existing wires.
c. Most pumps in the marketplace today usually have 1 inlet and 1 discharge ports from the left and right side of pump head. Therefore, they are limited to only 1 way of connecting the inlet/outlet fittings.
In view of this, there is a need in the industry for a pump that solves these shortcomings in the pumps that are known in art.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 2-8: The Dual Diaphragm and Manifold Assembly

FIGS. 2-8 show a dual diaphragm pump generally indicated as 10, according to some embodiments of the present invention. FIGS. 1-5 show the dual diaphragm pump generally indicated as 10 having a single inlet/outlet configuration. In contrast, FIGS. 6-8 show configurations for a dual diaphragm pump having a multiple inlet/outlet configuration. In either case, the dual diaphragm pump may be configured with a multipart pump housing, e.g., having a motor housing 11 a and a removable front cover 11 b, and may also include a pump stand or mount 11 c. FIG. 2A shows a motor 13 and a motor shaft/diaphragm actuator assembly 15 arranged in the multipart pump housing, which couples to upper and lower diaphragm pumping assemblies generally indicated as 12, 14 (see FIGS. 7A, 7B and 7C), e.g., that cooperate consistent with that described below. FIGS. 7A, 7B, 7C also shows the dual diaphragm pump configured with a pressure sensor or switch module 50 (see also FIG. 9B) that senses the pressure of the fluid being pumped, and provides a suitable pressure sensing signal containing information about the pressure sensed. Pressure sensors and/or switches are known in the art, and the scope of the invention is not intended to be limited to any particular type or kind thereof either now known or later developed in the future. In FIGS. 7A, 7B and 7C, the front pump housing for covering the configuration of the multiport manifold assembly is not shown, e.g., which is analogous to element 11 b in FIGS. 1-5. The scope of the invention is not intended to be limited to how the multipart pump housing may be configured, combined or assembled together, etc., e.g., including the number of discrete parts in the configuration, combination or assembly.
Moreover, FIGS. 2 through 4A and 8 show that the dual diaphragm pump may also be configured with a quick connector 60 (see also FIG. 9B) for coupling to a corresponding connector for providing electrical power to the pump, e.g., including from a wall mounted transformer (not shown). The quick connector 60 configured on the pump wiring allows a user to specify the connector they require, and the wiring from their system would be configured with a suitable mating connector and plug for coupling directly into the pump. This quick connector configuration 60 allows for a quick and safe removal of a pump for a power source for the purpose of servicing. Flexible wiring options may also be configured that also allow for remote mounting of signal input/output devices and a power input.
The Manifold Assembly 20, 20′
The diaphragm pump may include a manifold assembly like elements 20 and 20′, e.g., as shown in FIGS. 6 and 7.
By way of example, FIG. 7 shows the manifold assembly 20 equipped with internal input and output duckbill valves 30, 32, 40, 42 that allow for the passing of solids and particulate in the liquid being pumped without fouling or clogging the internal duckbill valves 30, 32, 40, 42. The integration of the internal duckbill valves 30, 32, 40, 42 allows the diaphragm pump 10 to handle higher viscosity fluids with less restriction and is capable of passing a larger particle medium of sizes up to 4 millimeters (mm) in diameter, especially when compared to the prior art pump shown in FIG. 1. The internal input and output duckbill valves 30, 32, 40, 42 can be reinforced with an internal support to prevent the respective valve from collapsing in applications that will generate higher back pressures during operation or when the pump is not running, e.g., consistent with that disclosed in U.S. Pat. No. 8,276,616 (Atty docket no. M-FLJ-0902//911-5.49-2) and U.S. Pat. No. 8,690,554 (Atty docket no.

FIGS. 7, 7A, 7B and 7C
FIGS. 7, 7A, 7B and 7C show multi-directional port configurations. In effect, the present invention allows for many different inlet/outlet port connections which provide for flexibility in certain tight, fixed spaces. By way of example, with the dual inlet ports, mixing of two (2) different fluids may be made possible as well; and the dual discharge ports allow for two (2) dispensing valves/faucets.
As shown, the dual inlet ports 20 a(1), 20 a(2) may be configured or oriented orthogonal to one another; and the dual outlet ports 20 b(1), 20 b(2) are configured or oriented orthogonal to one another, although embodiments are envisioned using other types or kinds of geometric relationship between the dual inlet ports, the dual output ports, or both.
The dual inlet ports 20 a(1), 20 a(2) and the inlet chamber 20 a may be configured to receive the fluid from two fluid sources (not shown) for mixing together in the inlet chamber 20 a; and the dual outlet ports 20 b(1), 20 b(2) and the outlet chamber 20 b are configured to provide a mixed fluid to at least one fluid outlet source (not shown).
The inlet duckbill check valve assembly 20 d and the outlet duckbill check valve assembly 20 e may be configured to process a particle medium having up to 4 millimeters (mm) in diameter.
Either the dual inlet ports 20 a(1), 20 a(2), or the dual outlet ports 20 b(1), 20 b(2), or both the dual inlet ports 20 a(1), 20 a(2) and the dual outlet ports 20 b(1), 20 b(2), may be configured to receive different port fitting connections.
It is noted that in FIGS. 7A, 7B and 7C the part of the pump shown does not include, by way of example, the front pump housing analogous to element 11 b in FIG. 2. A person skilled in the art would appreciate how to configured such a front pump housing without undue experimentation, e.g., based on that disclosed herein.
FIG. 6 shows an alternative embodiment of the manifold assembly 20′, having parts and components thereof labeled similar to the parts and components of the manifold assembly 20 in FIG. 7 with the additional of a single quote “′”. The manifold assembly 20′ is configured to operate in a manner substantially similar to the manifold assembly 20 (FIG. 7).
FIGS. 9A and 9B: The Controller
FIG. 9A shows a flowchart generally indicated as 100 having steps 100 a through 100 k for implementing control functionality according to the present invention for operating a pump, e.g., having at least some combination of the components shown in FIG. 9B, consistent with that set forth herein.
Controller 52—The electronics controller may include, or take the form of, an electronic PCBA 52, e.g., that may be internal to the pump, as shown in FIG. 9B.

- i. Steps 100 a and 100 b: Power may be applied to the pump via a power supply jack or an integral connector 60, which allows for direct power to the pump via the end user's source or from a wall mount transformer (not shown), so the On/Off switch 54 can be turned On.
- ii. Steps 100 c and 100 d: The control circuit 52 then applies power to the motor 13 and allows a pre-designated time for priming. If the pump exceeds that time and there is a low/no current draw condition, then the control circuit 52 shuts the power off. The control circuit 52 then sends a signal indicating that the pump has shut down due to a run dry/no power condition. By way of example, the signal may take the form of an audio or visual alarm, as well as a wireless signal provided to a remote location, including a wifi signal transferred via the Internet to a remote (e.g., off site) access point.
- iii. Steps 100 d, 100 e, 100 f: If the pump primes and is running, then the control circuit 52 monitors the current draw on the pump, and if the pump unit's current draw drops beneath a designated current range, whether by the fluid being pumped being exhausted or by some other issue, then the control circuit 52 will remove power to the motor 13. The control circuit 52 then sends a signal indicating that the pump has shut down due to a run dry/no power condition or an out-of-product being dispensed condition.
- iv. Steps 100 h, 100 i, 100 j: If the pump experience a high current draw, e.g., exceeding a pre-designated range, then the control circuit 52 will remove power to the motor 13 and then sends a signal indicating that the pump has shut down due to an over-current condition.
- v. By way of further example, if the power to the circuit board 52 should be removed by the pressure switch 50, e.g., due to an outlet (not shown) being shut off, then the control circuit 52 may be configured to remove power form the pump until the pressure is relieved at which time the control circuit 52 may be configured to automatically turn the pump back on and supply fluid.
- vi. By way of further example, if the pump runs continuously for a specified period of time, then the circuit board 52 may be configured to remove the power from the motor and sends a signal indicating the pump has shut down due to a continuous running or time-out condition.
- vii. By way of further example, the control circuit 52 may also be configured to precisely control the dispense amount and flow rate, e.g., by controlling the time and/or varying the voltage to the motor 13 using a pulse wave modulation (PWM) technique, or other method of motor speed control, including techniques both known in the art or later developed in the future.
- viii. By way of further example, the control circuit 52 may also be used for storing, communicating, and/or remotely adjusting the pump operating parameters/settings, pump performance profiles with various fluids and media, error codes, flow rate, and dispensed quantity information, power consumption, etc.

Possible Applications:
Food and Beverage dispensing/processing, Fluid and chemical transfer and mixing, any application that may require moving liquid with high viscosity, particulates and/or solids.
