A volute structure for a fly ash classifier

Abstract

The invention discloses a volute structure for a coal ash classifier in the technical field of coal ash classifying. The volute structure comprises a volute body and a manhole door arranged on the lateral wall of the volute body, wherein a connecting section is fixedly installed at the top end of the volute body, and the two ends of the connecting section are each fixedly provided with a cone through a steel ring; an upper plate is fixedly installed at the top end of the connecting section, and the two ends of the upper plate are fixedly connected with the volute body through upper plate reinforcement strips; a volute opening flange is fixedly installed at an opening in the left end of the volute body; a lower plate is fixedly installed on the outer wall of the bottom surface of the volute body; and the bottom end of the volute body is fixedly connected with a barrel, and a barrel connecting flange is fixedly installed at the bottom end of the barrel. The volute structure for the coal ash classifier has the advantages of being unique in process, novel in structure, simple in structure, convenient to operate, low in operation maintenance cost, high in separation efficiency, long in service life and the like. In addition, the volute structure is highly adaptive to coal ash, the cutting particle size range is wide, and the adjustment measure is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of fly ash classification, in particular to a volute structure for a fly ash 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 based on the principle of low-speed swirl separation, the general separator has the disadvantages of large resistance, high energy consumption, serious wear, etc., and the classification of fly ash mainly depends on wind force, through the The mixed g...
