Patent number: 10124315Abstract: In a water-absorbent resin production apparatus for producing a water-absorbent resin by polymerizing a water-soluble ethylenically unsaturated monomer, a water-absorbent resin powder obtained by drying a water-absorbent resin composition with a dryer passes through a first powder flow path pipe, is discharged therefrom toward a classifier while a flow rate is regulated so as to a predetermined value by a powder flow rate regulating discharge member composed of a hopper and a rotary valve, and is classified by the classifier. In the water-absorbent resin production apparatus, a collector for collecting a powder aggregate composed of aggregated particles of the water-absorbent resin powder is disposed in the first powder flow path pipe. Accordingly, a water-absorbent resin in the form of a particulate powder from which the powder aggregate is removed can be produced at a high production efficiency.Type: GrantFiled: February 23, 2016Date of Patent: November 13, 2018Assignee: SUMITOMO SEIKA CHEMICALS CO., LTD.Inventors: Muneaki Tanaka, Nobutsugu Okazawa, Masato Kotake
