Patent number: 10982901Abstract: A drying system includes a nozzle attached to an air supply duct of a drying chamber that blows out heated air inside the duct toward an object to be dried inside the chamber. The nozzle includes a horn-shaped inner-side surface made of pairs of first and second inner-side surfaces that respectively face each other in first and second directions, an opening width of the second surfaces in the second direction gradually increasing forward in a direction in which the air is blown and being 2 to 25 times inclusive larger than an opening width in the first direction. The drying system includes: the duct with the nozzles; a feeding device feeding air to the duct; and a heating device heats the fed air. The feeding device feeds air to the duct such that the air blown out from the nozzle spreads more in the first direction than in the second.Type: GrantFiled: November 6, 2017Date of Patent: April 20, 2021Assignee: TRINITY INDUSTRIAL CORPORATIONInventors: Manabu Hakata, Yasushi Kondo, Keiichi Suzuki, Kimihiko Sugiura, Satoshi Tamura

Patent number: 9777414Abstract: A bulkiness recovery apparatus for nonwoven fabric includes a hot-air source; and a case unit including a base member, and first and second members. The first and second members face opposite first and second surfaces of the base member and partition first and second conveyor spaces. The base member has first and second hot-air chambers. The first and second surfaces have first and second jet inlets. The first and second hot-air chambers at least partly overlap in a direction normal to the first surface. First and second conveying directions of the nonwoven fabric in the first and second conveyor spaces are different. Hot air flows along the first conveying direction and is blasted from the first jet inlet into the first conveyor space. Hot air flows along the second conveying direction and is blasted from the second jet inlet into the second conveyor space.Type: GrantFiled: September 25, 2014Date of Patent: October 3, 2017Assignee: UNICHARM CORPORATIONInventors: Jun Okuda, Satoshi Mitsuno

Patent number: 7565753Abstract: A dryer assembly includes a blower unit having an inlet and an outlet. A restriction mechanism having a plurality of louvers is disposed generally at the inlet of the blower unit with the louvers being moveable between an open position and a closed position. An actuation mechanism is in communication with the restriction mechanism. The actuation mechanism selectively restricts air to the blower unit by moving the louvers into the closed position.Type: GrantFiled: April 5, 2005Date of Patent: July 28, 2009Inventor: Todd P. Christopher

Patent number: 6412190Abstract: A combined infrared and hot air dryer includes a pressurized hood which is fed with combustion air through an air delivery duct. Each cross-direction zone of the hood includes a mixer. The air enters the mixer without any direct connection between the delivery duct and the mixer. Gas is supplied to each mixer from a gas manifold having a gas supply tube for each mixer. Excess air from the hood is fed through thin-walled tubes into the IR exhaust duct in a counter flow fashion to provide pre-heated clean air for air bars trailing the infrared zone.Type: GrantFiled: May 17, 2001Date of Patent: July 2, 2002Inventor: Thomas Smith

Patent number: 6161370Abstract: An endless transport belt made of thermoresistant synthetic filaments for transporting yarn is described, which yarn is wound around a plurality of transport belts in the form of loops, said transport belts being arranged polygonal in cross section. In order to reduce stretching of the transport belt, at least one reinforced thread is included among the synthetic filaments, which reinforced thread is preferably a steel wire or cord.Type: GrantFiled: November 30, 1998Date of Patent: December 19, 2000Assignees: Seil-Baur GmbH, Michael Hoerauf GmbH & Co. KGInventor: Tilman Bertram

Patent number: 6035551Abstract: An automated air filtration and drying system including an energy and environmental management system for controlling, monitoring and supervising the operation and performance of the air filtration and drying system, a capture apparatus for capturing and controlling overspray, and a drying control module for rapidly drying a coated article using a continuously filtered and dehumidified flow of recycled air.Type: GrantFiled: September 8, 1997Date of Patent: March 14, 2000Assignee: Optimum Air CorporationInventors: Fred G. Scheufler, Richard D. Scheufler, deceased, by Fred G. Scheufler, executor, William H. Bayard

Patent number: 5718061Abstract: An automated air filtration and drying system diffusor is disclosed which includes at least one pair of parallel overlapping panels to balance a flow of air in a filtration and drying system. Aperatures are located in each of the panels. The aperatures of a second panel block the aperatures of the first panel. In a preferred embodiment, air flow generated by a rotary blower includes aperatures positioned in a rotary center of the panels with openings having a greater surface area than aperatures positioned on an exterior of the panels. A greater velocity is generated by air passing through aperatures having a smaller relative opening, thus balancing or equalizing the air flow.Type: GrantFiled: January 15, 1997Date of Patent: February 17, 1998Assignee: Optimum Air CorporationInventors: Fred G. Scheufler, Richard D. Scheufler, William H. Bayard

Patent number: 5657555Abstract: In a process for drying coated surfaces in a hot-air dryer, part of the hot air in the dryer is continuously circulated therein as a secondary air stream which is mixed with a primary air stream heated to above the drying temperature (T.sub.max). This reduces the quantity of hot air to be fed into the dryer and thus the material requirements are reduced and the heating time shortened. A hot-dryer for implementing the process has, in the hot-air chambers (7,8) arranged symmetrically on either side in the interior (6) of the dryer, a separating wall (22) dividing an internal chamber (7) and an outer chamber (8) which has fun intake aperture (9) at its lower end for secondary air. At the lower end of the inner chamber (7), the primary air is fed in at a higher flow rate and mixed with the secondary air taken in through the aperture (9).Type: GrantFiled: March 20, 1996Date of Patent: August 19, 1997Assignee: ABB Flakt ABInventors: Dragoslav Milojevic, Manfred Losch

Patent number: 5363567Abstract: The self incinerating oven has a housing provided with opposed radiant walls which define an oven cavity. Each radiant wall is heated by heated air from a combustion chamber. Polluted air, containing volatile, organic compounds (VOC's), from the drying of painted objects in the oven cavity, is directed from the oven cavity, through ducts to suspended, recuperative, heat exchanger tubes in the incineration chamber. The preheated, polluted air, at 800.degree. F.-1000.degree. F. emerging from the heat exchanger, is discharged adjacent to a linear gas burner, in the combustion chamber. The VOC's are burned by the burner and part of the heated air and products of combustion are directed to heat one of the radiant walls.Type: GrantFiled: March 10, 1992Date of Patent: November 15, 1994Assignee: Thermal Engineering Corp.Inventor: Willie H.
