摘要： A pneumatic conveying apparatus operable to transport material from a supply source to a process which requires a rate of change of feed rate far in excess of what is possible from a typical pneumatic conveying system and pipeline alone, and for a process where storage of large volumes of material directly adjacent to the process feed point is either not possible or disadvantageous. The pneumatic conveying apparatus (100; 101;102) comprises at least one conduit (11) and a compression device (8) operable to supply and transport pneumatic media through at least one conduit (11). The supply source (1) may be a feed hopper and is operable to discharge material into the pneumatic conveying system downstream of the supply source. In the pneumatic conveying system at least one vessel (9; 9A, 9B; 20) is arranged to receive material from the supply source (1) and to discharge material to at least one conduit (11). The system also includes a filter receiver (4), which is configured to simultaneously receive and discharge material and pneumatic media from at least conduit. The filter receiver has a working volume or capacity which is very small in relation to the feed rate, typically 1 to 2 minutes storage when operating at the maximum discharge rate, and with a volume typically ½th to ⅛th of the volume of the vessels feeding material into the start of the pneumatic conveying pipeline. The filter receiver is equipped with a discharge device operable to increase the discharge rate to the process from the minimum feed rate to the maximum feed rate in a time period of 2 to 30 seconds. The filter receiver (4) is configured and operable to separate material and pneumatic media such that the material can be discharged from the filter receiver to the downstream process (2), in order to separate the conveying apparatus from the process and provide further advantages described within the invention. The apparatus includes a control system (19) that is operable to maintain a target weight and/or level within the filter receiver, and recover the target weight and/or level in the filter receiver, by measuring the weight and/or level and the rate of change of weight or level, of all storage vessels discharging material to the pneumatic conveying pipeline and process and incorporating aspects of closed loop control methodologies.
