Title:
CLASSIFIER AND POWER PLANT, AND OPERATION METHOD OF CLASSIFIER
Document Type and Number:
Japanese Patent JP2022156405
Kind Code:
A
Abstract:
To simplify fixation work of a reinforcement member and a blade.SOLUTION: A rotary typed classifier 16 rotates around a center axis C extending in a vertical direction, classifies pulverized solid fuel introduced from outside in the radial direction by carrier gas, and introduces the pulverized solid fuel whose grain diameter is a prescribed grain diameter or less into inside. The rotary typed classifier 16 comprises: a body part 70 which rotates around the center axis C; a plurality of tabular blades 60 which extend in a vertical direction and an upper part and a lower part of which are fixed to the body part 70; and a reinforcement member 80 which reinforces the plurality of blades 60. The plurality of blades 60 are arranged at the position maintaining a prescribed distance from the center axis C to outside in a radial direction, and are arrayed in a circumferential direction at a prescribed distance so that plate surfaces of the adjacent blades 60 in a circumferential direction face each other. The reinforcement member 80 is fixed to an inner end part of the blade 60 in a radial direction to connect the blades 60 arrayed in a circumferential direction with each other.SELECTED DRAWING: Figure 3
