一、设计特点及技术数据我局北炼厂技术改造,必须解决氧化锑粉的管道输送问题。由于正压输送较真空输送简便,又符合我局具体情况,因而决定采用正压输送方式。南炼厂目前采用的双缸输送泵输送锑氧是成功的,但体积大,设备笨重,投资较多。北炼厂原用的螺旋输送泵,是用螺旋给料机改制的,螺旋叶片为等 First, the design features and technical data I North Refinery technical transformation, we must solve the antimony oxide powder pipeline problems. Because of the vacuum transmission than the pressure is simple, but also in line with the specific circumstances of our bureau, which decided to use positive pressure delivery. The south cylinder refinery currently uses a two-cylinder pump delivery antimony oxygen is successful, but bulky, bulky equipment, more investment. North original refinery screw pump, screw feeder is used for restructuring, spiral blades and so on
