    摘要： A cleaning system for cleaning a pneumatic conveyance system used to transport particulate material. The pneumatic conveyance system includes a material-introduction device for introducing particulate material into a convey line, and a motive air source for generating an air flow to propel the particulate material through the convey line. The cleaning system comprises a projectile comprising a cleaning surface for cleaning an interior of the convey line as the projectile travels through the convey line, a launcher for injecting the projectile into the convey line, with the launcher being coupled with the convey line at a position upstream from the material-introduction device, and a catcher vessel for receiving the projectile upon said projectile exiting the convey line.

    摘要： Certain aspects of the subject matter described here can be implemented as a method. A location of an entrance to a pipeline pig launcher configured to launch a pipeline pig into a pipeline is determined by an automated pipeline pig handling system positioned at a starting location. The pipeline pig is self-aligned with the entrance to the pipeline pig launcher by the automated pipeline pig handling system. The entrance to the pipeline pig launcher is open. The pipeline pig is inserted by the automated pipeline pig handling system into the entrance to the pipeline pig launcher. The entrance to the pipeline pig launcher is closed by the automated pipeline pig handling system after the pipeline pig is inserted into the entrance. The automated pipeline pig handling system is self-returned to the starting location after inserting the pipeline pig into the entrance to the pipeline pig launcher.

    摘要： A pipeline (500) equipped with at least one pump (400) transports granules dispersed in a carrier fluid in intervals between co-transported pigs in a pipeline. Each pump and each pig is configured to preserve the intervals between pigs, and the orientation of the pigs, during passage of the pigs and granules through each pump. Also, each pig may comprise peripheral apertures providing a leakage of carrier fluid into the intervals downstream of each pig as a means of preserving the dispersion of granules within the pipeline. In the example shown granules are introduced to the pipeline by inlet feed hopper (400), and granules are removed from the pipeline at outlet delivery hopper 650. Hopper 404 introduces pigs at the pipeline inlet and hopper 652 removes pigs at the pipeline outlet: pigs are returned to hopper (404) by the pipeline (500A).

    摘要： An improvement of a high density pneumatic transport system for pneumatically transporting powdered or granular materials placed in an airtight storage container to a collector through a transport pipe having a vertical riser pipe intermediately thereof by the use of pressurized gas. The transport pipe comprises a lower horizontal pipe being connected to the airtight storage container and having a convergent cylindrical accelerating reducer, an upper horizontal pipe being connected to the collector and having a divergent cylindrical decelerating reducer at its initial end, and a vertical riser pipe which connects the lower horizontal pipe to the upper horizontal pipe. The vertical riser pipe is provided at intermediate thereof up and down with an acceleration regulating reducer having a convergent accelerating portion above its bottom having a constricted portion and a divergent cylindrical decelerating reducer.

    摘要： There is disclosed a horizontal type hydrohoist, in which slurry is forced to feed under lower pressure into feed pipes which are connected to a transport pipeline at their one ends and to a high pressure clear water pump at the others, said pump being adapted to deliver clear water under a high pressure, after which clear water is transferred under a high pressure through said feed pipe from said high pressure clear water pump, thereby transferring said slurry. This hydrohoist system presents the provision of means for preventing mixing and its spreading at the boundary portion between slurry and water within the feed pipes. More particularly, a separator which is designed not to rotate during the transfer is inserted in the aforesaid boundary portion in a manner that the separator may be transferred together with fluid, thus preventing the mixing of water with slurry as well as the resultant spreading thereof. According to a further aspect of the invention, at the completion of the slurry transfer under a high pressure, the separator is caused to be gradually slowed down to stop for the purpose of obviating a water hammer phenomenon within the pipings. In addition, after the removal of the slurry remaining around the separator by using a high pressure water, the feeding of the high pressure water is interrupted, thereby preventing mixing and its spreading at the boundary portion of water with slurry at the time of the subsequent introduction of slurry under lower pressure.

    摘要翻译： 公开了一种水平型水力搅拌器，其中迫使浆料在较低压力下进料到在其一端连接到运输管线的进料管中，并在另一端连接到高压清水泵，所述泵适于输送 在高压下清水，之后通过所述高压清水泵通过所述进料管在高压下将澄清的水转移，从而转移所述浆料。 该水驱系统提供了防止混合和在进料管内的浆料和水之间的边界部分扩散的装置。 更具体地说，在转移期间设计成不转动的分离器以分离器可与流体一起转移的方式插入上述边界部分中，从而防止水与浆料的混合以及由此产生的扩散。 根据本发明的另一方面，在高压下的浆料转移完成时，为了避免管道内的水击现象，使隔膜逐渐减速停止。 此外，在通过使用高压水除去残留在隔板周围的浆料之后，中断高压水的供给，从而防止混合，并在随后的浆料中在浆料的边界部分扩散 在较低压力下引入浆料。
