  • Patent number: 9422114
    Abstract: Disclosed is a device for improving the method of manufacturing Archimedes screws by assembling sectors on a shaft without forming gaps, cutting edges or weak regions between one another and ensuring the continuity of the turns of which the screw consists. It consists of a sector having a turn with a length equal to one screw thread and having a geometry that enables it to be interlocked with another, identical sector. The turn sits on a core, the geometry of which is obtained by following in each case a helical generatrix which is offset through at least one turn thickness. The terminal face of the turn is inclined at an angle with respect to the axis of the sector. The device according to the invention is particularly intended for the production of systems for metering or pumping viscous, pulverulent or granular products, the systems including at least one Archimedes screw.

  • Patent number: 8403127
    Abstract: The introduction of a heterogeneous solid substance, such as biomass, into a container which is under pressure is difficult. The rotary valves and airlocks used hitherto have substantial deficiencies. The use of standard screw conveyors has hitherto failed due to the fact that a cavity formed behind the screw helix in which gas could escape from the pressurized container. These deficiencies are resolved in that two independently controllable screws are arranged in a screw conveyor pipe. Between the primary screw driven by a motor and the secondary screw driven by another motor, the biomass is compacted by high pressure as a consequence of the different revolution speeds of the motors in such a way that an almost gas-tight plug is formed. The invention is particularly well-suited for the introduction of biomass into a gasification installation which is under pressure, for the production of synthesis gas.

  • Patent number: 7743912
    Abstract: A conveyor feeding system for reliably and continuously supplying particulate matter as feedstock, such as rubber tire chips, to a reactor or distillation unit. The feeding system includes a pair of inclined spiral augers having their lower ends submerged in oil or other liquid to provide a liquid seal, thereby preventing undesirable back flow of distillation gases through the feeding system. The push auger acts to push lightweight feedstock downward, submerging it through the liquid seal. The material thereafter is taken up by the partially submerged feed auger, for withdrawal up out of the liquid seal for delivery to further processing, such as a pyrolytic reactor. Buoyant material, which otherwise might float upon the liquid of the seal reservoir, accordingly may be effectively processed through the system.

  • Patent number: 7428956
    Abstract: An auger assembly transfers particulate material from a source area to a target area using a main auger, an intermediate swing auger and a loading swing auger connected in series with one another. The main auger is supported on a wheeled frame similar to conventional grain augers while the intermediate swing auger is pivotal thereon and the loading swing auger is pivotal on the intermediate swing auger. The inlet hopper of the auger assembly can thus be more easily positioned relative to the main auger for proper alignment with the discharge hopper of a particulate material container even when the discharge hopper is within a confined space.

  • Patent number: 7192094
    Abstract: An auger support assembly for use with an augering system for mining which bores a pair of side-by-side holes through a coal seam using dual side-by-side augers. Each auger includes a drilling section which is followed by a series of auger flights for conveying the bored coal back out of the respective hole. The augers are connected together in axially aligned pairs and are supported by the auger support assembly. The auger support assembly includes a pair of bearing housings that are disposed on drive shafts which extend outwardly from the first ends of a first pair of parallel augers and are received within the second ends of a second pair of parallel augers. The bearing housings are connected to each other by a tie bar. A single support leg extends downwardly from approximately the mid-section of the tie bar to engage the ground ledge that is formed between the counter rotating augers.
