  • Patent number: 10669497
    Abstract: A transportable and combustible gaseous suspension includes solid fuel particles suspended in a gaseous carrier. The solid fuel particles have a sufficiently small particle size so that they remain suspended during transportation. The gaseous carrier may include reactive and inert gases. The solid fuel particles may include coal-derived solid carbonaceous matter. Other examples of solid fuel particles include biomass, refined bioproducts, and combustible polymer particles. The combustible gaseous suspension can be tailored to have an energy density at atmospheric pressure which is comparable to conventional gaseous hydrocarbon fuels. The gaseous combustible fuel may be pressurized to a pressure in the range from 2 to 100 atmospheres.

    Abstract: A dispensing head for a powder or paste dosage material has a housing with an outlet opening, a bearing- and passage area, and at least one socket connected to a source container. A feeder chute is formed inside the housing. A closure shaft is in the bearing- and passage area, free to rotate about and to slide along its central longitudinal axis. The closure shaft is connected to a closure element arranged near the outlet opening. Moving the closure shaft in the axial direction controls the volume flow of the dosage material through the outlet opening. A limit stop restricts the displacement of the closure shaft along its central longitudinal axis. In the feeder chute, an opposing stop defines the closed position where the limit stop rests in direct contact against the opposing stop and the outlet opening is closed off by the closure portion of the closure element.

  • Patent number: 6945287
    Abstract: A backflow blocker prevents backflow of gas to a lower pressure first stage of a system for processing particles from a downstream higher pressure second stage of the system. The blocker comprises an upright duct connecting the first stage to the second stage. The duct is at least partly filled with a column of particles passing from the first stage to the second stage. By properly selecting the duct dimensions and by controlling the flow rate of particles into and from the duct, the velocity of downwardly moving particles in the duct can be made to exceed the velocity at which the gasses flow through the particles in the duct. This prevents gasses from flowing from the lower pressure downstream stage to the higher pressure upstream stage.

  • Patent number: 4470525
    Abstract: The present invention is directed to a vibrating screen agitator in a coal storage hopper for assuring the uniform feed of coal having sufficient moisture content to effect agglomeration and bridging thereof in the coal hopper from the latter onto a conveyor mechanism. The vibrating screen agitator is provided by a plurality of transversely oriented and vertically spaced apart screens in the storage hopper with a plurality of vertically oriented rods attached to the screens. The rods are vibrated to effect the vibration of the screens and the breaking up of agglomerates in the coal which might impede the uniform flow of the coal from the hopper onto a conveyer.

  • Patent number: 4392591
    Abstract: A multistage volumetric feeder has a storage hopper for storing a mass of semi-flowable material, such as strand fiberglass, asbestos, or titanium dioxide. The material is bottom unloaded and passed through several stages of pressure reduction, aeration, and conditioning to loosen the material and place it in a state of substantially constant density. The conditioned material is further prevented from bridging and compacting as it is volumetrically delivered to a metering stage through a segregation stage. Because the semi-flowable material is placed in an uncompacted state of substantially constant density, the feeder is capable of delivering a precise mass of material over a wide range of flow rates.

  • Patent number: 4363428
    Abstract: When poultry or other livestock feed is stored within a bin having a conical bottom, the feed can become packed and bridge across the bin bottom opening. Under such circumstances, delivery of feed to an underlying conveyor may be erratic under some conditions. To overcome this, the present invention provides a first rotatable shaft extending upwardly along the axis of the bin bottom cone. A second shaft is joined to the first shaft by a universal joint. Mounted on the second shaft are a number of poly-sided discs. Here, these discs are equilateral triangles, and the triangle corners or points are bent out of the plane of the mediate disc portions. Arrangements are provided for locking the discs to the second shaft. If desired, a feed support disc can be carried by the first shaft below the second shaft so as to at least temporarily support feed which has been dislodged by the rotating poly-sided discs above it.

The hopper has a bottom discharge passage under which is mounted metering apparatus providing a plurality of discharge openings of controllably variable size. An upper impeller having a plurality of downwardly angled blades is rotatably driven within the hopper passage to urge the flock fibers to fall downwardly through the discharge openings into a cylindrical pump chamber. A lower impeller is rotatably driven within the pump chamber to sweep falling flock fibers into a pump throat in communication with a venturi flow tube through which a supply of air is passed. The air flowing through the venturi flow tube creates suction to draw the fibers within the throat into the venturi flow tube for entrainment with the air stream.

  • Patent number: 3981417
    Abstract: A mass of particulate material stored in a hopper is bottom unloaded and passed through several stages of aeration and fluidization to condition the material and place it in a relatively uncompacted state. The material is conditioned with a minimum of vibration of the material mass so that the mass remains a homogeneous mixture of densities and does not stratify into powdery and coarse materials. The conditioned material is fed to a distributor ring wherein it is further aerated and fluidized into an uncompacted state and moved in a uniform volumetric flow through an annular array of holes into a pneumatic conveyor. Because the material is placed in an uncompacted state while being maintained as a homogeneous mixture of densities, a very precise mass of material may be metered out as a linear function of the time of delivery. With the present system, preselected masses of material can be delivered with extremely high accuracy.
