Special rotary grading machine for pulverized fuel ash

Abstract

The invention relates to the technical field of pulverized fuel ash grading machines, and discloses a special rotary grading machine for pulverized fuel ash. The special rotary grading machine for pulverized fuel ash comprises a motor, wherein a rain hood is fixedly mounted at the top of the motor through a bracket; the bottom of the rain hood is fixedly connected with the top end of an observation bin through the bracket; the bottom end of a speed reducer is coaxially connected with a shaft rod; the shaft rod extends to an inner cavity of the observation bin; a fine ash outlet is formed in the left end of the observation bin; a rotating wheel is arranged at the lower end of the observation bin; the rotating wheel is rotationally mounted at an inner cavity of a rotating wheel bin; a tapered platform is mounted at the bottom of an inner cavity of the rotating wheel; the bottom of the shaft rod is rotationally mounted at an inner cavity of the tapered platform; an outer ash bucket is fixedly mounted at the bottom end of the rotating wheel bin; an inner ash bucket is fixedly mounted at an inner cavity of the outer ash bucket; a square air tube is arranged at the bottom end of an inner cavity of the inner ash bucket; a rectangle-to-round joint is fixedly mounted at the left end of the square air tube; the left side of the rectangle-to-round joint is connected with a manual butterfly valve through a pipeline.

Description

technical field [0001] The invention relates to the technical field of coarse and fine classification of fly ash, in particular to a rotary fly ash special classifier. Background technique [0002] Fly ash can be divided into first grade, second grade and third grade according to the fineness. Their fineness is the same, they are all about 325 mesh, just because they pass through the sieve with 325 mesh fineness. The probabilities are different, so it is divided into first-class, second-class and third-class. More than 88% of the fly ash can pass through the first-class fly ash, 70% of the pass-through is the second-class fly ash, and 55% of the pass-through is the third-class fly ash. Ash, the currently used fly ash separation system is a special equipment suitable for fly ash separation developed after a long period of extensive tests based on the principle of low-speed swirl separation. Since the equipment was put into use, it has provided a number of One hundred sets of...
