发明名称 Screw-fed pump system
摘要 A pump system includes a pump that includes a first belt and a second belt that are spaced apart from each other to provide generally straight sides of a passage there between. There is an inlet at one end of the passage and an outlet at an opposite end of the passage, with a passage length that extends between the inlet and the outlet. The passage defines a gap distance in a width direction between the straight sides at the passage inlet. A hopper includes an interior space that terminates at a mouth at the passage inlet. At least one screw is located within the interior space of the hopper and includes a screw diameter in the width direction that is less than or equal to the gap distance.

主权项 1. A pump system comprising: a pump including a first belt and a second belt that are spaced apart from each other to provide generally straight sides of a passage there between, with a passage length extending between an inlet at one end of the passage and an outlet at an opposite end of the passage, the passage defining a gap distance in a width direction between the straight sides at the passage inlet; a hopper including an interior space that terminates at a mouth to the inlet; and at least one screw within the interior space of the hopper, and the at least one screw includes a screw diameter in the width direction that is less than or equal to the gap distance, wherein the screw is configured to meter a particulate for downward axial movement.
