Современная промышленность в XXI веке требует высокопроизводительной и полностью автоматизированной техники. Лучшим способом удовлетворить эти требования является внедрение новых прогрессивных технологий в процессы транспортирования.Одним из возможных способов повышения производительности, а также автоматизации процесса транспортирования является переход от машин цикличного действия к транспорту непрерывного действия, а именно к ленточным конвейерам. Однако с увеличением длины конвейера возникает потребность в более прочных лентах. Избежать этого возможно, используя промежуточные приводы различных конструкций.В статье описан принцип работы промежуточного линейного привода с поперечными перегородками, приведены формулы для расчета значений тягового усилия, даны сравнительные графики, показывающие эффективность применения промежуточного привода в различных условиях. Описаны возможности увеличения тяговой способности промежуточного линейного привода.
In the modern world, in modern circumstances industries require high-speed technologies and fully automation. The best choice to satisfy these requirements is to implement new technologies with progressive features into transportation processes. This article describes the options for increasing traction of the belt conveyor intermediate drive. The functioning principle of the intermediate linear drive with transverse baffles has been described, formulas for calculating the values of traction effort have been provided, also comparative graphs that show the efficiency of using the intermediate drive in various conditions, have been given.
Deep sea solid mineral resources (SMR) of the World Ocean, such as ferromanganese nodules (FMN), cobalt-manganese crusts (CMC) and the depth polymetallic sulphides (DPS) should become an alternative source of mineral resources in the near future. Reliable and productive complexes are necessary for the implementation of deep-sea mining on an industrial scale, which will be able to develop deposit with a minimum ecosystem load. So, the main problems in technological solutions are the collection or separation of SMR at the bottom and lifting them to the surface. As a technical solution, it is proposed to use a special construction draghead device for FMN and CMC collecting and separating from the bottom. The distinctive feature of the device is a vertical axis of rotation of the drive engine and the working body, which can be represented by a faceplate or a crown, the working element with the engine are concentrically inscribed in the casing with the catcher, which enclose the loosening zone, protecting surrounding water area from the turbulent mud and separated fractions. Nodules and crusts lifting using the draghead is carried out in the form of slurry through a pipeline.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
