Patent number: 11623164Abstract: A separator for separating wellbore emulsions into liquid and gaseous components has helical emulsion preheat coils encircling a single-cylinder, dual chamber firetube disposed inside a horizontal separator vessel. In use, emulsion enters the preheat coils before entering the separator vessel. The flow of emulsion through the helical coils promotes initial separation of the emulsion by means of heat transfer and centrifugal flow. Resultant centripetal force separates lighter gaseous and liquid particles toward the inside of the helical coils, while heavier emulsion fractions condense toward the outside of the helical coils. The use of helical preheat coils and a single-cylinder, dual-chamber firetube eliminate or minimize abrupt changes in emulsion flow direction that are characteristic of prior art separators, resulting in reduced wear in both the coils and the firetube.Type: GrantFiled: March 17, 2022Date of Patent: April 11, 2023Assignee: Red Deer Iron Works Inc.Inventors: Tyson Smith, Todd Chamberlain, Kelly Chamberlain

Patent number: 11583788Abstract: A filtration system using lightweight fibrous media (LFM) that are pre-compressed either 1) manually; or 2) in-situ using hydraulic flow; and where the LFM are forced to separate and relax for cleaning either: 1) manually, 2) in-situ in their filter housing, or 3) in an auto-clean system using separate devices in order to enact a particularly aggressive cleaning process. A plurality of lightweight fibrous media balls are pre-compressed and used to form a single mass that can filter water as the media are compressed by pre-compression before installation, or by water flow pushing on a pre-compression plate during filtration thereby forming a single mass providing multitudes of tortuous paths through which water can flow and the media can capture small particulate matter.Type: GrantFiled: May 17, 2022Date of Patent: February 21, 2023Inventors: Theodore A.

Patent number: 11524252Abstract: A filter, for insertion into an inlet duct of a water filtration system, has an annular upper end delimiting an opening around a longitudinal axis and defining a filter diameter. A side wall extends, around the longitudinal axis, between the annular upper end and a bottom wall that extends opposite the opening. The side and/or bottom walls have orifices to allow water to flow therethrough while retaining solid elements. The sidewall wall comprises a plurality of arms that each extend between a lower edge, connected to the bottom wall, and an upper edge forming part of the annular upper end. Each arm extends along an adjustable inclination so that the filter diameter is variable according to the inclination of each arm. When the filter is inserted into the inlet duct, the inclination of the arms is adjusted so that the filter diameter is adapted to the inlet diameter.Type: GrantFiled: December 6, 2018Date of Patent: December 13, 2022Assignee: ABP—Aquilina Bouvier PoolInventors: Yann Aquilina, Matthieu Bouvier

Patent number: 11504655Abstract: A backwashing suction device for a fabric filtration apparatus, and more particularly, a backwashing suction device for a fabric filtration apparatus in which an edge surface of a suction slit through which pile threads exit is inclined to form a slope so that the pile threads introduced into the suction slit when a fiber disk filter is rotated for backwashing come into contact with the slope and thus the amount of angular rotation of the pile threads is increased to increase the backwashing effect. Also, since a plurality of friction protrusions are formed to protrude from the slope, the effect of removing foreign substances can be further enhanced through the effect of rubbing and washing the pile threads on a washboard while the pile threads ascend over each of the friction protrusions one by one.Type: GrantFiled: February 12, 2021Date of Patent: November 22, 2022Assignee: GRENEX LIMITEDInventors: Chungchang Kuk, Younglong Kuk

Patent number: 11492195Abstract: A disposable oil filter containment sheath is provided for use during oil changes for combustion engines. The sheath has a closed bottom, a cylindrical sidewall, and an open top. The resilient sheath is rolled to an initial collapsed position for placement on the bottom of an oil filter mounted on the engine, and it is partially unrolled along the filter. The filter can then be loosened to allow oil to drain into the sheath for capturing a reservoir. After the filter is removed from the engine, the sheath is completely unrolled and tied at the top so as to fully enclose and contain the oil filter and oil. The sheath and its contents are then ready for disposal.Type: GrantFiled: February 28, 2020Date of Patent: November 8, 2022Inventor: Cap Shafer
