Method for pump-feeding polyethylene granule and equipment for material pump-feeding from container by using the method

The invention discloses a method for pump-feeding polyethylene (PE) granule and equipment for material pump-feeding from a container by using method, which belongs to the distribution system of PE granules. The PE granule pump-feeding method comprises a feeding process and a pumping process, wherein the pumping speed is greater that the feeding speed. The container pumping and feeding equipment comprises a material chamber I and a material chamber II, wherein the material chamber I is connected with the material inlet of a rotary valve; a filter core tube is arranged in the material chamber I and is connected with the container; and the material outlet of the rotary valve is connected with the material chamber II. In the invention, the pumping speed is greater than the feeding speed, thus ensuring that raw materials can not be filled in an impeller tank so as not to be cut; the material chamber I and material chamber II with a Roots blower, thereby achieving that the raw materials in the container are pumped
