Macerator pump apparatus with an integral waste valve assembly and a quick disconnect discharge assembly

摘要

A macerator pump apparatus (MPA) includes a waste valve assembly (WVA), a macerator assembly, a pumping assembly, and a quick disconnect discharge assembly (QDDA). An inlet port of the WVA receives waste matter from a waste holding tank (WHT). A valve member positioned within the WVA directs flow of the waste matter to the macerator assembly and isolates the waste matter within the WHT by closing the valve member before the MPA is disassembled for maintenance. The macerator assembly macerates the waste matter and transfers the macerated waste matter to the pumping assembly and to a discharge port of the QDDA. A quick disconnect member detachably connects an outlet plumbing pipe to the discharge port via a quick disconnect valve (QDV) for discharging the macerated waste matter. The QDV isolates the macerated waste matter within the outlet plumbing pipe by closing the QDV before the MPA is disassembled for maintenance.

1. A macerator pump apparatus, comprising:
a waste valve assembly, comprising:
an inlet port detachably connected to a waste holding tank, said inlet port configured to receive waste matter from said waste holding tank;a valve body defining a valve cavity, said valve cavity in fluid communication with said inlet port; anda valve member positioned within said valve cavity of said valve body, said valve member configured to direct flow of said waste matter from said valve cavity to a macerator cavity of a macerator assembly in fluid communication with said valve cavity via a macerator adaptor, said valve member further configured to isolate said waste matter within said waste holding tank by closing said valve member before said macerator pump apparatus is disassembled for a maintenance operation; said macerator assembly removably fastened to said waste valve assembly, said macerator assembly comprising a macerator housing defining said macerator cavity configured to receive said waste matter from said valve cavity of said waste valve assembly, said macerator assembly configured to macerate said waste matter in said macerator cavity and transfer said macerated waste matter to a pump cavity of a pumping assembly in fluid communication with said macerator cavity; said pumping assembly fixedly connected to said macerator assembly, said pumping assembly comprising a pump housing defining said pump cavity configured to receive said macerated waste matter from said macerator cavity of said macerator assembly, said pumping assembly configured to pump said macerated waste matter to a discharge port of a quick disconnect discharge assembly in fluid communication with said pump cavity; and said quick disconnect discharge assembly operably connected to said pumping assembly, said quick disconnect discharge assembly comprising:
said discharge port extending from said pump housing of said pumping assembly, said discharge port configured to receive said macerated waste matter from said pump cavity of said pumping assembly;a quick disconnect member operably connected to said discharge port, said quick disconnect member configured to detachably connect an outlet plumbing pipe to said discharge port via a quick disconnect valve for discharging said macerated waste matter; andsaid quick disconnect valve configured to detachably connect said quick disconnect member to said outlet plumbing pipe, said quick disconnect valve further configured to open and close said outlet plumbing pipe to direct flow of said macerated waste matter through said outlet plumbing pipe, said quick disconnect valve further configured to isolate said macerated waste matter within said outlet plumbing pipe by closing said quick disconnect valve before said macerator pump apparatus is disassembled for said maintenance operation.
