摘要： A compact dedusting apparatus induces air flow through the housing by a vacuum generator mounted within the housing. The discharge of dust and debris can be passed through a conduit to a remote location without losing air flow velocity to facilitate the use of the compact dedusting apparatus within a clean room. The metering device is formed from stainless steel and mounted on a spring-loaded mounting plate to permit vertical movement of the metering device when a jam of the particulate material is encountered. The metering device can be driven by a low torque stepper motor operable at selectively variable speeds to control the flow rate of the particulate material. The discharge transition is formed with an enlarged cross-sectional area compared to the shape of the Venturi zone so that carryover pellets can be returned to the product flow instead of being lost with the dirty air discharge.

摘要： A half round dedusting apparatus for removes dust and debris from particulate material passing through the dedusting apparatus. The configuration of the dedusting apparatus includes a half round cylindrical housing in which is mounted a partial cone wash deck having a reverse partial cone deflector that is vertically moveable to vary the flow rate of particulate material passing over the wash deck. The product inlet port is preferably circular and directs contaminant-laden particulate material inside the deflector to pass over the surface of the wash deck. The housing has a greater diameter than the maximum diameter of the wash deck to establish a Venturi zone around the circumference of the wash deck. The wash deck and deflector are detachably mounted within the housing to allow removal thereof for ease of cleaning the wash deck and also the interior of the housing.

摘要： A compact dedusting apparatus induces air flow through the housing by a vacuum generator mounted within the housing. The discharge of dust and debris can be passed through a conduit to a remote location without losing air flow velocity to facilitate the use of the compact dedusting apparatus within a clean room. The metering apparatus is formed as a fixed shape device that closes against the floor of the infeed hopper to prevent the flow of particulate material into the dedusting apparatus. The fixed shape device is connected to a pneumatic cylinder mounted externally of the infeed hopper to provide selective vertical movement to the metering apparatus. Vertical movement of the metering apparatus is limited by slots formed in a mounting plate. The fixed shape member passes through the mounting plate for engagement with the pneumatic cylinder.

摘要： A cylindrical dedusting apparatus has an upper material infeed opening to introduce material into a frusto-conical infeed hopper centered over the tip of a conical wash deck supported over an air infeed conduit. Air is blown through slots and openings in the surface of the wash deck to separate dust and debris from the particulate material. The dust-laden air is discharged by passing between the infeed hopper and a cylindrical sleeve to enter into a circular collector for discharge from the apparatus. Flow rate of material over the wash deck is adjusted by vertically moving the infeed hopper within the sleeve relative to the wash deck to vary the dimension of the gap through which material flows onto the wash deck. A closed loop air system can be used with the cylindrical dedusting apparatus with a bleed air module that reduces air flow into the apparatus.

摘要： A dedusting apparatus is formed with a rectangular inlet structure that assures a fully loaded feeding of particulate material over the face of the opposing wash decks. A rectangular inlet box having substantially the same width dimension as the corresponding dimension of the adjacent wash decks provides an even distribution of particulate material over the entire surface of the wash decks. A reconfiguration of the air inlet structure eliminates a rearward air plenum and manifold by passing the air flow upwardly through the bottom wall of the apparatus housing, rather than through the rear wall. Individually adjustable inlet deflectors can regulate the product flow on each respective wash deck and can be closed to stop the product flow completely to either one or both of the wash decks. Actuators control the movement of the deflectors, which can be integrated in an overall electronic control system for the dedusting apparatus.

摘要： A compact dedusting apparatus for cleaning particulate materials of contaminates and has a housing defining a cleaning area in which the contaminants are removed to create cleaned particulate material with a product discharge opening through which cleaned particulate material can be discharged. The dedusting apparatus includes an infeed apparatus having a vibratory feed pan powered by a vibration generator to induce vibrations therein. The dedusting apparatus also includes a Venturi chamber to remove contaminants from the particulate material by a flow of air passing upwardly through the product discharge opening. The dedusting apparatus further includes an interchangeable carryover deflector having a chamber extension member that aligns with internal structure to control the flow of particulate material into said Venturi chamber and deflects particulate material entrained in the air flow through the Venturi chamber toward the product discharge opening. The carryover deflector incorporates an observation window to view the dedusting operation.

摘要： A rotary valve meters the flow of particulate material from a supply source into a pneumatic conveying system and includes a central rotor rotatable within a cylindrical housing. The interior surface of the cylindrical housing is formed with grooves extending from pinch points at the inlet opening to facilitate the passage of particulate material past the pinch points without being trapped between the rotor vanes and the housing. The grooves are preferably formed in a configuration that has an increasing depth from the proximal wall to the distal wall, and preferably is configured with a spiraled surface shaped to increase the depth of the groove channel to a rounded end chamber at the distal wall. The groove channels can be oriented in alignment with a triangular ridge, in a circumferential direction perpendicular to the direction of movement of the rotor, or perpendicular to the angle of the triangular ridge.
