Pulse pump

a pump and pump body technology, applied in the direction of flexible member pumps, machines/engines, positive displacement liquid engines, etc., can solve the problems of preventing the flow of fluid from reaching the drainage network beneath the floor, the drain tube extending from this equipment to the drainage network can become blocked, and the buildup of fluid is difficult to eliminate within the relatively small drain tube passages

Benefits of technology

"The present invention is a pulse pump with various embodiments that operate the pump diaphragm using an electric drive motor controlled by a power switch. The pump has a diaphragm that is driven back and forth in a chamber by an eccentric rotor. The pump has one-way check valves at the inlet and outlet ports or passages. The diaphragm can be devoid of openings or have a toroid configuration. The invention provides a solution for pumps that need to operate in a controlled and efficient manner."

Problems solved by technology

As the accumulation increases, so does the potential for drain line blockage and resulting backup.
The drain tube extending from this equipment to the drainage network beneath the floor can become blocked with sugar “snakes,” i.e., buildup, in a relatively short period of time and it can be difficult to eliminate such buildup within the relatively small drain tube passages.

first embodiment

[0036]FIG. 4 of the drawings provides a view of the pump assembly 10 of the first embodiment with the cover of the actuator mechanism removed, to show more clearly the details of this mechanism. A non-circular output shaft 46 extends from the gear reduction drive 14, and extends into or through an axially offset mating passage in an eccentric rotor 48. As the output shaft 46 rotates, the rotor 48 oscillates eccentrically due to the non-concentric installation of the output shaft 46 therein. The rotor 48 resides within an oval-shaped passage 50 within the reciprocating diaphragm actuator 52, which in turn drives the diaphragm assembly 18 as explained further below. The rotor 48 is free to oscillate laterally within the oval passage 50 of the actuator 52, but the narrower vertical dimension (i.e., normal to the plane of the diaphragm) of the oval passage 50 results in the rotor 48 drawing the reciprocating actuator 52 upwardly and downwardly relative to the plane of the diaphragm (ill...

embodiment 210

[0060]The first inlet valve assembly 22a has an inlet line connector or fitting 26a extending therefrom, which would connect to the supply line 30 from the reservoir 42 if the pump assembly 210 were installed in lieu of the pump assembly 10 of FIG. 1. The opposite outlet line connector or fitting 28a communicates with the second inlet connector or fitting 26b of the second inlet valve assembly 22b via an intermediate tube 30a. In a like manner, the outlet fitting 28b of the second outlet valve assembly 24b communicates with the inlet fitting 26c of the third inlet valve assembly 22c via another intermediate tube 30b, with the third outlet fitting 28c of the third outlet valve assembly 24c communicating with the inlet fitting 26d of the fourth inlet valve assembly 22d. Finally, the outlet fitting 28d of the fourth outlet valve assembly 24d connects to an outlet line, e.g., the line 32 of the pump assembly shown in FIG. 1, if the multiple valve pump 210 were used in lieu of the single...

embodiment 10

[0061]Otherwise, it will be seen that the multiple diaphragm and valve pulse pump system includes various features found in the various embodiments of the single diaphragm assembly 10 of FIGS. 1 through 9B. For example, the fourth or final outlet valve 24d includes an anti-siphon valve assembly 114 extending therefrom, which function is identical to that described further above for the pulse pump embodiment 10. It will also be seen that while a series of four diaphragms 80a through 80d and corresponding valve bodies 20a through 20d, inlet valve assemblies 22a through 22d, and outlet valve assemblies 24a through 24d with their inlet and outlet valves 110a through 112d are shown in FIGS. 10 through 13, other arrangements or configurations may be constructed in keeping with the concept described above. For example, two of the four diaphragm actuator plates may be eliminated during assembly, with only two diaphragms and two inlet and outlet valve assemblies remaining operable and interc...

Abstract

The pulse pump is driven by an electric motor and gear reduction driving an eccentric rotor, which, in turn, oscillates a mechanism actuating a diaphragm to transfer fluid through one-way check valves. The pump may be used in a number of different applications, but is particularly useful in applying biodegradation material to consume grease and other biodegradable matter typically found in drainage systems of food processing facilities, converting such matter into carbon dioxide and water. The device includes a system for placing the mechanism in a neutral position when the pump is deactivated, to avoid causing the diaphragm to take a set toward either extreme of travel when parked for an extended time. One embodiment incorporates a multiple piece actuator assembly having a diaphragm sandwiched between components. Another embodiment uses a single piece actuator having a circumferential groove, with the diaphragm having a toroid configuration and attaching within the groove.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 272,559, filed Oct. 6, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to fluid transfer pumps. More specifically, the present invention is a reciprocating pulse pump driven by an eccentric rotor and incorporating an electronic system for neutralizing the position of the diaphragm when the pump is inoperative.[0004]2. Description of the Related Art[0005]Relatively small reciprocating pumps incorporating a flexible diaphragm and one-way check valves are used in a number of different fields and environments. In the food processing industry, e.g., restaurants, bakeries, canneries, and the like, processing activities result in the generation of byproducts such as grease, oil, flour, sugar, and other organic matter that tends to adhere to the inner surface of drain lines. As the accumulation increas...
