    Abstract: An efficient flexible sorting device for material flow is provided. The gear A is driven by the rotating motor, and the gear A meshes with the gear B, so that the rotating body can be rotated relative to the main frame according to the sorting direction actually required. The belt motor rotates the driving shaft through the small synchronous pulley, the synchronous belt, and the large synchronous pulley. The driving shaft drives the belt to move along the tensioning roller, the driving shaft, and the guiding pulley. The relative position of the tensioning roller and the rotating body is adjusted through the bolt F, the fixing plate and the nut F to ensure that the belt is tensioned, thereby realizing the sorting process.

  • Patent number: 8726532
    Abstract: Methods and systems are disclosed for drying a material or, more generally, flash evaporating a target substance having a vapor pressure threshold. The methods and systems include a conveyor conduit that receives material. The material moves through the conveyor and is expelled into a pressure drop zone created by one or more venturi nozzles. As the material encounters the pressure drop zone, the targeted substance in the material experiences a rapid and extreme pressure drop and simultaneously a rapid temperature increase. This causes the target substance in the material to flash evaporate virtually immediately. The resulting vapor is separated from the remaining material and the now dry material is collected for further processing or use. The vapor can be collected, condensed, exhausted, or otherwise treated depending upon the goals of a particular installation or process.

  • Patent number: 7255829
    Abstract: A method and an apparatus for the thermal treatment of metallic workpieces with which gas quenching can be obtained that is low in distortion, even for workpieces with an undulating shape or workpieces that are projectingly stackable are provided. In accordance with the method, after being heated the workpieces are cooled in a quenching chamber with a quenching gas, whereby the quenching gas is intentionally caused to flow around the workpieces by means of guide channels that have a closed lateral surface and that enclose the workpieces along the direction of flow of the quenching gas. The apparatus comprises a quenching chamber in which the workpieces can be cooled with a quenching gas, and wherein guide channels are provided to ensure that the quenching gas flows around the workpieces, the guide channels having a closed lateral surface and enclosing the workpieces along the direction of flow of the quenching gas.

  • Patent number: 7226286
    Abstract: An apparatus for guiding, treating, or advancing at least one yarn (1), comprising a delivery roll (2) and a companion roll (3) cooperating with the delivery roll so that the yarn repeatedly loops the delivery roll (2) and the companion roll (3). The delivery roll and the companion roll are driven by associated electric motors (7, 8), which are controlled via control lines (9) at a desired frequency by a controller (10). To enable an equalization of the circumferential speeds of the delivery roll (2) and the companion roll (3), the electric motor of the companion roll is an asynchronous motor that is controlled by the desired frequency and has a motor slip.

  • Patent number: 7004753
    Abstract: A gas seal protects the material inlet openings and material outlet openings of reactors for treating strands of material and strips of material. The openings are sealed by gas curtains. These curtains are generated by gas streams that leave gas outlet openings or nozzles and that are directed at an angle into the interior of the furnace. According to the invention, gas guide bodies, which extend adjacent the strands of material or strips of material substantially parallel to the surfaces of these strands of material and strips of material in the direction of the interior of the reactor, are mounted at the gas outlet openings. The gases leaving the gas outlet openings are guided in the gas guide spaces that are formed between the gas guide bodies and the strands or strips of material, in a targeted manner and under a slightly raised pressure in the direction of the interior of the reactor and thereby effect a significantly improved gas seal.

  • Publication number: 20040173239
    Abstract: The invention relates to a method for recovering the glass fibres from composite materials in connection with recycling. This is of particular importance in connection with recycling of glass fibre blades from wind turbines and other fibre reinforced composite materials of the type where glass fibre is embedded in a matrix of polyester, epoxy or a similar polymeric substance or a thermoplastic material. The method of the invention consists in a thermal process in which the material is pyrolysed at a relatively low temperature in a closed furnace chamber with an inactive atmosphere, for example in the form of nitrogen. The temperature and combustion conditions are chosen such that the matrix is glasified while the glass fibres remain intact, thus making recycling possible. The by-product of the pyrolysis is combustible gas, which is carried off from the furnace.

  • Patent number: 6514072
    Abstract: This invention is for a novel method of treating carbon fiber. Carbon fiber is a very unique material and its processing requires high temperatures. Also since carbon fibers are lightweight and porous, heating is accomplished in this process by radiation with a heated gas flowing through the material. Also a float is used to transfer the material from one process station to another so as to prevent delaminating of the carbon fiber.
