    摘要: Proposed is an equipment for reducing specific air pollutants generated from heated asphalt concrete with proportional control, which includes: a dryer for heating and drying aggregates and for burning harmful gases introduced through nozzles mounted thereon; a first dust remover for removing dust from the harmful gases emitted from the dryer; a fine dust remover for filtering fine dust from the remaining gases and dust; a bypass damper for returning some of the gases and dust emitted from the first dust remover to a second dust remover; the second dust remover for filtering the dust in the gases and dust emitted from the first dust remover; and a blower for feeding the gases exhausted from the second dust remover to the dryer, wherein clean gas exhausted from the fine dust remover is emitted to the air through an exhaust fan and a stack.

    摘要: A dryer adapted for use in an asphalt plant. The dryer includes a drum having an inner wall and a flight having a proximal end connecting the flight to the inner wall of the drum and a distal end that is spaced apart from the proximal end. A first profile extends from the proximal end to the distal end of the flight and defines a flight shape. A notch is formed in the distal end of the flight, which notch includes a notch shape that is defined by a second profile. The second profile has a length L, a center point, and a portion that substantially approximates a conic section.

    摘要: A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a rotatable drum that receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube at least partially disposed within the drum is configured to introduce a flow of air into the drum.

    摘要: A dryer for a textile web includes a drying chamber having at least one air-permeable drum arranged in the drying chamber to rotate, wherein the drum includes an end face constituting an axially arranged suction side, the textile web is wrapable at least partially around the drum and heated drying air is flowable through the textile web. A hot gas source provides heated gas. A ventilator forms a suction draft via the suction side of the drum with drying air from inside of the drum and drying air that recirculates back into the drying chamber. At least one hot gas feeding ring encloses the suction draft and is configured to permit the hot gas from the hot gas source to flow essentially completely into the suction draft.

    摘要: A seed drying system for positioning a manifold in a seed treater includes a seed treater that contains a plurality of seeds that have been coated with a liquid treatment. A manifold is positioned within the seed treater and a fan is provided to selectively urge air. The fan is fluidly coupled to the manifold to direct the air over the seeds thereby facilitating the liquid treatment to dry on the seeds. A mounting unit is provided and the manifold is coupled to the mounting unit such that the mounting unit retains the manifold in a horizontal orientation. The mounting unit is releasably coupled to the housing such that the manifold is retained in the drum. Moreover, the mounting unit centrally positions the manifold in the aperture.

    摘要: A dual tumble dryer unit that includes a housing that defines an interior, a divider that extends between first and second side walls and divides the interior into first and second sections, and first and second dryer assemblies that are positioned in the first and second sections. The first and second dryer assemblies each include a basket positioned to rotate about a horizontal axis, and a blower disposed positioned to blow air on the basket. A first drying path is defined between a first entry opening defined in the first side wall, the first basket and a first exit opening defined in the second side wall, and a second drying path is defined between a second entry opening defined in the first side wall, the second basket and a second exit opening defined in the second side wall.
