| 摘要 | PURPOSE: To facilitate the conveyance of powder without using compressed air by attaching powder suck-up blades to a shaft projected from the lower end of a rotor, and by forming a powder delivery port in a pump casing. CONSTITUTION: When a rotor 6 is rotated by a motor 3 through a connecting rod 4 after a guard 9 for a single shaft eccentric screw pump 1 being laid on powder in a container, suck-up blades 7, 8 attached to a shaft 10 projected from the lower end of the rotor 6 are rotated so that the powder is sucked up into a stator 5 while being agitated. Further, the powder is press-fed under pumping action by the stator 5 and the rotor 6 so as to be discharged into a discharge chamber 4 from a discharge port 5b, and then is delivered from a powder delivery port 2a in a pump casing 2. With this arrangement, it is possible to simplify the arrangement of the facility in its entirety since no compressed air is used for the conveyance of the powder. COPYRIGHT: (C)1989,JPO&Japio |
