20080223759 | Housing for a Particulate Material Dedusting Apparatus - A compact housing for a dedusting apparatus utilizes a magnetic flux field to disrupt the static charge attracting dust particles to product particles, which along with fluidization and counter current airflow principles that are proven to dislodge dust particles from the product, provides a highly efficient, compact deduster. The housing supports a double wash deck with product flow separated between the back-to-back primary wash decks. A deflector directing the flow of product onto the primary wash decks is provided with an extension that extends parallel to the wash deck to eliminated product bouncing off of the wash deck. The lower air outlets are eliminated, while the upper air outlets are positioned in extensions to the main housing above the product inlet opening. Air flow through the Venturi zones is enhanced by directing clean air through slots formed in the lower deck members into the Venturi zones. | 09-18-2008 |
20080307603 | Infeed Device for Dedusting Apparatus - An infeed device provides a configuration that improves the flow of particulate material into a double wash deck dedusting apparatus. The infeed device is formed with a circular inlet opening, an oval-shaped discharge opening and step sides interconnecting the inlet and discharge openings to prevent bridging in particulate material being fed through the infeed device onto the wash decks. The infeed device can be formed as a separate member that can be inserted into the infeed opening of existing dedusters. The oval-shaped discharge opening is substantially smaller transversely than the diameter of the inlet opening, but has a longitudinal length that is equal to the diameter of the inlet opening and equal to the longitudinal length of the wash decks. The joinder of the wash decks is blunted to eliminate a divider edge on which plastic streamers can hang up while being fed to the wash decks. | 12-18-2008 |
20100236583 | Cylindrical Dedusting Apparatus for Particulate Material - 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, the tip serving as a stopper to define the dimension of the gap through which material flows onto the wash deck. Cleaned material passes through a lower discharge opening while dirty air is removed through a radially oriented discharge conduit from the circular collector. | 09-23-2010 |
20100276921 | Elbow Fitting with Removable Wear Member for Pneumatic Conveying System - An elbow fitting for a pneumatic product conveying system expands from the inlet pipe along the outer side of the elbow fitting to enable a layer of accumulated product particles to be formed so as to move at a lower velocity than the velocity of the incoming product stream while establishing a moving contact surface for deflecting incoming product particles toward the outlet pipe with a minimum of pressure resistance and product attrition. The outer portion of the elbow fitting is removable from the body portion to allow the outer portion to be replaced when wear becomes an issue in the performance of the elbow fitting. The wear member is affixed to the body portion by a flange that creates a seam extending from the step feature diagonally to the rear wall. A gasket or O-ring is trapped within the flange to seal the wear member against the body portion. | 11-04-2010 |
20120020747 | Pneumatic Conveying Process for Particulate Materials - A pneumatic conveying process transports plastic pellets from a manufacturing source to a bulk silo for storage before being delivered to the ultimate production utilization of the plastic pellets. Multiple types or multiple sources of plastic pellets can be fed through a common pneumatic conveying conduit to respective bulk silos for temporary storage with diverter valves being utilized to direct product into and out of the common conveying conduit. Expanded elbow fittings are deployed at each directional change in the conveying lines to eliminate the creation of streamers at conduit bends. The plastic pellets are conveyed at a medium velocity between dense and dilute phases to provide a gentle conveying operation. A closed loop air supply system is used for dedusting devices providing a final removal of dust and debris from the stored product before being delivered to the ultimate utilization facility. | 01-26-2012 |
20130068263 | Method of Removing Contaminates from Particulate Material - 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, the tip serving as a stopper to define the dimension of the gap through which material flows onto the wash deck. Cleaned material passes through a lower discharge opening while dirty air is removed through a radially oriented discharge conduit from the circular collector. | 03-21-2013 |
20130074282 | Cylindrical Dedusting Apparatus for Particulate Material - 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. | 03-28-2013 |
