  • Patent number: 8770388
    Abstract: A sweep conveyor extends along a bin floor between a sump pivot about which the conveyor rotates, and an outer end adjacent the bin wall. During the conveyor's orbit about the floor, flights at the conveyor bottom sweep across the floor toward the sump pivot, whereby bin material in front of the conveyor is swept into a sump. The conveyor is preferably made in modular sections connected end-to-end, whereby different sections are combined to construct conveyors having different lengths and capabilities. Some sections are preferably hinged together, allowing different sections to adopt different inclinations as they travel about a non-level floor. The flights are preferably provided on a belted chain riding on sprockets at opposite ends of the conveyor, and the chain is not supported by idler sprockets along its length, allowing the chain (and its flights) to sag under gravity so the flights ride along the bin floor.

  • Patent number: 4676711
    Abstract: A moving gate discharge system designed to prevent product-breakage while discharging particulate products, particularly non-free flowing and inter-engaging particulate products, in a more uniform flow from a receptacle having a moving bottom, is disclosed. The system includes an endless circulating feeder mounted across the discharge of the receptacle with its lower end portion oscillating upwardly and downwardly and traveling at a horizontal speed more rapid than that of the product on the moving bottom of the receptacle. Product-progressing finger assemblies are mounted in transverse rows on the feeder, spaced distances equal to the longitudinal distance the feeder moves during one period of vertical movement of the lower end portion thereof, and located such that each will be disposed directly below the lower end portion of the feeder when the latter reaches the lower portion of its downward movement.

  • Patent number: 4618304
    Abstract: An upright silo has a U-shaped central discharge opening in the floor and a cavity below the floor in vertical alignment with the opening. A hopper in the cavity has an upright wall terminating at an upper edge and a smooth, inclined slip ramp contiguous with the edge and rigidly secured to the floor along the opening. The horizontal configurations of the opening, the cavity, the wall and the ramp are identical. The silage falls freely from a cutter arm above the floor into the hopper such that unloading time is substantially decreased. In one embodiment, a rake is movable within the cavity adjacent the ramp and is operable to break up otherwise lodged silage. In another embodiment, a somewhat similar rake has an outer segment which is pivotal about a vertical axis for retraction when not in use.

  • Patent number: 4616573
    Abstract: A metering feeder for delivering solid fuels, such as municipal or industrial refuse, for combustion includes a pair of generally vertically arranged hoppers. An upper hopper containing relatively compacted or intertangled fuel discharges metered amounts of fuel into a lower hopper through the action of a ram-type pusher. Fuel discharged from the upper hopper is dropped into the lower hopper to develop sufficient kinetic energy to decompact the fuel. An upwardly inclined conveyor removes fuel from the lower hopper at an independently metered rate under optional control of a combustion control system. The action of the inclined conveyor further decompacts the fuel by underraking and mixing, thereby providing a well controlled, uniform, loose density fuel for combustion. The conveyor has a closed course of cleats which cyclically moves to remove fuel. The cleats extend in acute angular relation to the direction of movement for improved performance.

  • Patent number: 4580939
    Abstract: A filter feed onto a fluted drum has conveyors which convey a stack-like stream of filters into a small reservoir adjacent to the drum. As they enter the reservoir, the filters are deflected upwards by a deflector plate so that the thrust by the conveyors does not produce a direct pressure of filters onto the drum. Instead, the filters are fed onto the drum by gravity after passing over the plate. A pivoted sensor plate over the reservoir controls the speed of the conveyors.

  • Patent number: 4545309
    Abstract: There is disclosed a furnace for burning wooden wastes and, more specifically, sawdust and/or barks. The furnace is provided with an oil burner required for starting the fire. The draught from the oil burner fan is directed within a perforated box, located in the combustion chamber of the furnace, and the sawdust or the barks or other wooden particles fall, according to a measured flow, over the perforated box. The sawdust is first alighted by the oil burner flame, and combustion thereafter builds up thanks to the draught from the perforated box. This box draught comprises a vertically-upwardly-oriented vector, for alighting the wood particles before the latter reach the box, and a horizontal vector extending toward the interior of the furnace to force the burning particles away from the side wall of the furnace. The system includes measured flow feeding system for the sawdust and/or the bark, and having a pair of flap-doors to prevent the escape of smoke from the furnace.

  • Patent number: 4512705
    Abstract: A horizontal plow system method and apparatus has been developed for the homogenous blending and reclaiming of bulk solid particulate matter, such as coal, at a utility plant. The horizontal plow system apparatus comprises one or more displacement assemblies, each further comprising a receiving stationary top plate and a horizontal flight subassembly. Coal is deposited via gravitational forces from an elongated slot bin storage onto the receiving stationary top plate and is then pushed on a bias and ultimately displaced by angular flights during travel of the horizontal flight subassembly along the receiving stationary top plate. Operation of the displacement assembly serves to displace the bulk solid from the sides of the receiving stationary top plate such that portions of coal from along the entire length of the elongated slot bin storage are continuously and simultaneously falling onto a moving transfer belt below, thereby insuring a more even blending of the coal.
