摘要： A method and system for conveying material in a pneumatic material conveying system includes a material input point, a material conveying pipe connectable with a feed-in container, the system being configured to provide a pressure difference in the material conveying pipe that includes a partial-vacuum generator, and a separator device in which the transported material is separated from the transport air at an outlet end of the material conveying system. The material is conveyed in a first stage from the input point to a conveying pipe, into a container space of an intermediate container arranged between the input point and the separator device by a suction/pressure difference provided by the partial vacuum generator in a first time period, and the material conveyed into the container space of the intermediate container is conveyed by a suction/pressure difference provided by the partial-vacuum generator to the separator device.

摘要： The invention relates to a separator for separating a conveyed medium, preferably air, from a conveyed material (4). Said separator comprises a container (1) which has at least one feed line (3) for the conveyed medium/conveyed material mixture, at east one outlet for the conveyed material (4), and at least one outlet (8) for the conveyed medium. In order to avoid abrasion damage at high conveying speeds or to ensure that said abrasion damage occurs at most only to a small extent, while nevertheless ensuring that the conveying medium and conveying material are reliably separated, an impact wall (14), which adjoins a cover wall (15) at an angle thereto, is located in the housing (1) opposite and at a distance from the outlet end (10) of the feed line (3) in the inflow direction (13) of the conveyed medium/conveyed material mixture. Said impact wall covers the inflow path of the conveyed medium/conveyed material mixture, blocking it from the outlet (8) for the conveyed medium. The conveyed material (4) hits the impact wall (14), which causes the kinetic energy of the conveyed medium to dissipate. The speed of the conveyed medium reduces very quickly after exiting the feed line (13), meaning that it cannot entrain any conveyed material.

摘要： Assemblies, apparatuses, and methods to extract or convey a material from a source of the material may include a vacuum generation and sound attenuation assembly and a material receiver to enhance conveyance the material from the source of the material. The vacuum generation and sound attenuation assembly may include a vacuum source positioned to cause a vacuum flow between the source of the material, the material receiver, and the vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may further include a sound attenuation chamber positioned to receive at least a portion of the vacuum flow from, and attenuate sound generated by, the vacuum source. The material receiver may be positioned an elevated location relative to a source of the material and be capable of staging and metering the conveyance of material when moving material at the top of a structure, such as a refinery tower.

摘要： A system and method for loading material from a converter bed, such as that in a converter of an acid plant, is provided. The system, may include a vacuum source; a dust collector connected to the vacuum source by a first vacuum hose; a cyclone operatively connected to the vacuum source through the dust collector, wherein the cyclone may be connected to the dust collector by a second vacuum hose; a drop-out hopper operatively attached to the cyclone by a valve, such as an air actuated valve, wherein the drop-out hopper includes a first feed hose; and one or more material storage containers operatively associated with the cyclone via a second feed hose. The method of loading material into a converter bed may include providing a system for loading the material in the converter bed; setting up the system; and loading the material into the converter bed.

摘要： A method and a dense phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or the like installation for spraying coating powder are disclosed. In order to reduce the number of components of the dense phase powder pump that require maintenance, the dense phase powder pump is designed as a single-chamber dense phase powder pump and has only a single powder conveyor chamber for conveying coating powder.

摘要： A hopper loader having a hopper connected to a vacuum source for applying a vacuum to the hopper to convey material into the hopper through a material inlet. A material separator is disposed between the material inlet and the vacuum source for filtering the material. A material discharge assembly is connected to the hopper and disposed for controlling downwardly gravity flow of the material from the hopper, the material discharge assembly having a material outlet configured to be opened and closed to control the discharge of material from the hopper. A vacuum detector is disposed between the material separator and the vacuum source. A vacuum activated control operatively connected to the vacuum detector and configured to turn off the vacuum source in response to a signal from the vacuum detector.
