Abstract: A pre-separator for separating out large particles from a fluid flow has a housing forming an interior chamber with an inlet and an outlet, and a separator plate in the chamber between the inlet and outlet. The separator plate has a surface facing the inlet that is provided with a liquid carrying tank into which the flow is directed when it enters the interior chamber through the inlet. The separator plate has a series of nozzle openings therethrough adjacent its periphery to the outside of the tank. The nozzle openings adjacent the periphery of the separator plate overlie a surface of the housing adjacent the outlet. The pre-separator thus has two impaction stages that permit use across a wide range of flows. The separator plate and the housing have surfaces which are tapered so that liquid in the housing can be drained out when the housing is inverted.

Abstract: An air material separator may be used to separate scrap from a conveying air flow while having a relatively low weight and short height so that the separator may be positioned within today's single-story manufacturing or processing facilities. The air material separator of the invention includes a generally cylindrical inlet chamber having a spiral wall that directs the inlet flow circumferentially and downwardly. An outlet chamber is positioned below the inlet chamber and includes a conical, perforated wall that allows the conveying air flow to escape through the perforated wall. The scrap carried by the conveying air flow cannot pass through the perforated wall and moves down and out an outlet at the bottom of the conical wall. The overall height of the device is substantially less than prior art air material separators.

Abstract: A chamber has a drive shaft rotatably mounted therein and extending along substantially the entire longitudinal extent of the chamber. This drive shaft is rotatably driven by a motor at a speed of 1,200-10,000 rpm. A plurality of screens having a mesh of 6-10 mesh are spaced from each other along the longitudinal extent of the chamber in opposing relationship and attached to the drive shaft for rotation therewith. Above the screens are a pair of discs which are attached to the shaft for rotation therewith and longitudinally spaced from each other. First and second similar plates having circular apertures formed therein are fixedly attached to the chamber in longitudinally spaced relationship, the first and second discs being positioned in the apertures of said first and second plates respectively. Gas to be purified is fed into the bottom of the chamber and driven upwardly by a compressor fan attached to the drive shaft.

Abstract: A rotor assembly includes a shaft and a plurality of radially outwardly extending vanes surrounded by a circular cylinder. A truncated conical segment screen is in each compartment formed by the vanes dividing each compartment into inner and outer subcompartments. Apertured top and bottom face plates are respectively above and below the vanes. A housing includes top and a bottom plates to which the rotor assembly shaft is rotatably secured. A material inlet hose and dust exhaust pipe are attached to the top plate and are in simultaneous successive fluid communication with each outer and inner subcompartments respectively as they rotate. A discharge port is in the bottom plate for discharging separated material in an outer subcompartment downstream from the outer subcompartment then receiving material from the inlet hose. The top and bottom plates are spaced a small gap from the rotor face plates to provide fluid seals therebetween to fluid isolate the compartments from each other.

Abstract: The invention provides a separator for removing small particulates from an air stream, the separator includes pneumatic separator with a relatively small filter element built inside the separator to remove particulates from the air stream down to as small as one micron. The pneumatic separator relies on a vortex effect and sudden changes in direction of the air flow to strip out most of the particulates, and because the very small particulates have insufficient mass to be dislodged from the air in this way, these particulates remain in the air stream and are carried to the filter element where they build up on the element. The build up is interrupted by the incoming air which flows aggressively around the element and strips parts of the build-up off the element. This ongoing random process can be supplemented if necessary by back flushing. Both the separated particulates and those stripped off the filter element accumulate in the separator for subsequent removal.

An inlet disposed towards the top portion of the housing is in communication with the flow of air and the supply material and is in further communication with the chamber. It is adapted to direct the flow of air and the supply material into the chamber. The chamber is adapted to facilitate swirling of the airflow and the supply material within the chamber. A cone-shaped air rotation circulator is in communication with the chamber and is configured to facilitate the flow of air directed into the chamber in a circular motion within the chamber.

Abstract: A mobile vehicle containing fluorescent lamp separation apparatus is transported to the site of a facility which uses fluorescent lamps and collects used lamps for processing. The lamps are loaded into a bin in the vehicle, the bin is closed to enclose the apparatus from the atmosphere, and the apparatus is then operated to crush the lamps and separate the crushed lamp debris into solid particular matter and dust which can be carried by airflow. The particulate matter which is substantially cleansed of mercury and phosphor powder is discharged into a first receptacle outside the vehicle, and the dust entrained in the air is trapped in a dust filter and discharged into a second receptacle which primarily contains the more hazardous dust materials. The air drawn through the dust filter is further passed through a charcoal filter to filter out mercury and other potentially hazardous vapors from the air before it is discharged to the atmosphere.

Abstract: An apparatus and method for reaching a 99% separation of bast and core fibers from herbaceous fiber producing plants using a series of pre-separation cleaning and conditioning steps which place the bast and core fibers in a better condition for separation before they are actually separated. The harvested fiber plants are cut at a specified length. These fibers are then introduced into a conditioning apparatus which breaks up and dries, but does not yet separate the bast and core fibers. The conditioned fibers are then introduced into an auger and feeder which distributes the dried fiber over up to four identical separation lines. Each line includes at least one core separator made up of a large rotating spiked cylinder partially surrounded by a spiked, grated housing, a smaller rotating spiked cylinder which produces an air flow, and an upwardly moving inclined conveyor having openings therein.

Abstract: A dry washer for separating small high density particles such as gold from a mixture of high and low density material. A rotatable impeller in a cylindrical chamber draws in air and mixed particles, such as sand, and fractures the larger particles. The mixture of air and particles passes to a helical conduit having a perforated partition spaced from the outer wall so that high density particles pass through the wall under centrifugal forces. The particles are passed from the helical conduit to an inclined upper trough including an air permeable floor and riffles or the like to retain the high density particles. Air flow from the helical conduit is directed to a lower trough below the trough. A damper at the end of the lower trough causes air to pass through the air permeable floor and blow away fine low density particles. Dust and air from the trough assembly is passed to an elongated cover to collect the fine, low density, particles.

Abstract: A method for separating the long outer bast fibers from the short woody inner core fibers of herbaceous fiber producing plants which includes the steps of requiring that such plants harvested at a certain cut length are processed through a first and second stage core separator, each of which includes a rotating spiked cylinder and a set of angled moving conveyors for coarse separation of the bast and core fibers; then processed through a first and second incline core separator each of which include a series of rotating spiked cylinders provided at an inclined angle; then introduced into a single saw separator; then passed through a jet air separator having an adjustable blade therein; and finally, run through a four cylinder fiber cleaner. Each of these steps provides further and more complete separation of the woody core fibers from the longer bast fibers so that by the time the bast fibers exit the four cylinder cleaner they are over ninety-eight percent (98%) free of the woody core fibers.

Abstract: A rotary air separator having a manifold with a side opening and an end opening. A cylindrical screen rotates around the manifold over the side opening and the end opening is connected to a vacuum source. Vanes in the manifold segregate the side opening into discrete areas. The vanes define independent throats for directing air in a curved transitional path from the side opening areas to the end opening. A collar surrounding the side opening defines a curved inlet to the side opening and provides an effective air barrier to inhibit air flow from around the manifold.

Abstract: A catalyst loading hopper suitable for positioning in vertical position above a reactor vessel, having an inlet at its upper end, a catalyst outlet at its lower end and a diagonally-disposed baffle extending downwardly across the hopper but terminating short of one of the walls of the hopper and a weir adjustably arranged so as to control the flow of catalysts through the hopper. There is a dust outlet at the top of the hopper, which may be connected to a conduit so as to draw dust away from the upper end of the hopper and a screen at the bottom of the hopper to separate the catalyst from any fines or undersized catalyst particles. The screen feeds into a catalyst outlet which, in turn, feeds into a conduit, which extends into the reactor vessel so as to allow arrangement of the cleaned catalyst pellets in layers in the vessel. A gas nozzle opens in the wall of the hopper and allows dust to be blown from the catalyst pellets and through the dust outlet to be collected in a suitable filter.

Abstract: A cyclic screening apparatus (10) and method utilizes multiple air flows and differential air pressures to separate undersize and oversize particles from a mixture of 5 to 50 micron size particles. The apparatus (10) comprises a support (12) including a first conduit (14) connected to a blower (16). A lower undersize particle collecting housing (20) has a secondary air inlet (24) and outlet (26) connected to a suction fan (SF). A screen is clamped between the lower housing and an axially movable and pivotable upper receiving housing. An air distributor rotor (R) is slowly rotated below and directs the first air flow through the screen and into the upper chamber and through a lower portion (40) and against the bottom of lower housing. A rotary nozzle (80), with the help of incoming secondary air flow, disperses particulate material onto the screen below.

Abstract: A method of deinking comprises: (a) mechanically fiberizing a secondary fiber source in a substantially dry state, preferably air dry, thereby producing a fibrous material consisting of substantially discrete fibers and ink-bearing fines: (b) depositing the fibrous material onto a moving screen or wire which retains fibers and allows fines to pass therethrough; and (c) lifting the fibrous material above the screen with upwardly directed forced air and redepositing the material onto the screen, whereby upon re-deposition of the material, additional fines pass through the screen.

Abstract: Self-cleaning separator apparatus is used in combination with a vertical settling chamber for extracting fiber product from a moving air stream. The separator apparatus includes a housing forming an air stream inlet, a product discharge outlet and a clean air outlet. A rotatable screen is interposed between the air stream inlet and the clean air outlet for collecting the fiber product on the screen as the air stream flows through the screen for discharge into the atmosphere. An air flow gradient is induced in the settling chamber whereby the air flow rate through the rotating screen is substantially smaller near the bottom of the settling chamber than it is near the top of the settling chamber. The gradient is produced in part by a transversely extending baffle plate mounted in the annular flow region near the product discharge outlet, and in part by the off-center placement of the rotary screen closely adjacent the sidewalls of the settling chamber which converge toward the product discharge outlet.

Abstract: Method and filter apparatus for extracting entrained lint particles from an effluent air stream prior to discharge into the atmosphere. The filter apparatus and method are used in combination with a vertical settling chamber for separating relatively dense fiber product from airborne lint entrained in a product stream. The filter apparatus includes a housing forming an air stream inlet, a product discharge outlet and a clean air outlet. A rotatable screen is interposed between the air stream inlet and the clean air outlet for collecting the entrained lint on the screen as the effluent air stream flows through the screen for discharge into the atmosphere. Bulk fiber product which settles to the bottom of the chamber is discharged through a rotary valve in the product discharge outlet. The accumulated lint deposit is presented to the product discharge outlet as the screen turns.
