  • Patent number: 10926207
    Abstract: When a liquid flows into a case along a tangential direction at an arbitrary point on a side surface of a filter case from an inflow pipe provided substantially around an outer periphery, at the side surface of the filter case, a swirling flow is produced in the liquid flowed and air contained in a fluid is collected in a center portion of the swirling flow to generate bubbles. The inflow pipe and a filter element are positioned not to overlap each other in a height direction, whereby the liquid flows into a hollow portion of a filter element from a case while swirling. The bubbles generated in the center portion of the swirling flow are released to a space above a liquid surface of the fluid retained in a tank through an air outlet portion formed in an upper end surface or the side surface of the filter case.

  • Patent number: 7934606
    Abstract: The induced vortex particle separator is a device for separating solid particulate matter from a liquid containing such particulate matter. The liquid enters a housing through an inlet port and is driven about a helical vane to form a helical flow path. Upon exiting the helical vane, the liquid is received within a central portion of the housing where a centralized structure including an annular stator and an inverted diffuser cone drive the liquid to form a free vortex. Under centrifugal force, the solid particulate matter is separated from the liquid and flows, under the force of gravity, into a lower region of the housing. Due to a negative pressure differential, the liquid is driven upwards within an inner cylindrical shell mounted within the housing to flow into a siphon for output through an outlet port.

  • Patent number: 7578870
    Abstract: A fluid separator device allows for introducing air entrained in a liquid flow to a centrifugal pump in a manner that will not allow the pump to become gas bound. One example device designed according to this invention includes a housing having an inlet and an outlet downstream of the inlet. An air chamber is positioned on an opposite side of the inlet from the outlet. An air flow passage allows air from the air chamber to be introduced near a rotor assembly input of a centrifugal pump such that relatively small air bubbles are introduced to the liquid flow through the rotor assembly in a manner that prevents the air bubbles from recollecting into a larger bubble that would otherwise interfere with the centrifugal pump operation.

  • Patent number: 7556785
    Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.

  • Patent number: 7288139
    Abstract: An apparatus separates liquid, gas and solid components of a mixture in a fluid system. An inlet for receiving the mixture opens into a separation chamber tangentially with a cylindrical side wall and a gas outlet has an opening in a first end wall adjacent the inlet to allow gas to exit the separator. A fluid outlet is located in an opposing second end wall. A debris passage extends through the cylindrical side wall and oriented so that the radial velocity of the particles within the separation chamber directs the particles through the debris passage. The debris passage leads to a particle collection chamber in which the particles accumulate. Unlike prior separators that relied on the tangential velocity of the particles, the present apparatus utilizes the greater radial velocity to drive the particles from the separation chamber into the particle collection chamber.
