Multi-stage separation fly ash separator

Abstract

The invention provides a multi-stage separation fly ash separator which comprises a housing, wherein a grading bucket is arranged in the middle of the housing; an impeller is mounted in the grading bucket; an impeller shaft is connected with a motor fixed at the top of the housing; a coarse ash outlet is formed in the lower part of the grading bucket; a coarse ash pipeline is connected to the outer part of the coarse outlet; a material inlet is formed in one side of the upper part of the housing; and a fine ash outlet is formed in the bottom end of the housing. The multi-stage separation fly ash separator is characterized in that a screening chamber is arranged at the upper part of the housing; a vibrating screen is mounted at the center of the screening chamber; and a large-particle material opening is formed in one side of the screening chamber. The equipment realizes a multi-stage fly ash separation function, has the advantages of simple structure, no dust spilling phenomenon and good grading effect, and is convenient to operate.

Description

technical field [0001] The invention relates to a material separation device, in particular to a multi-stage separation fly ash separation machine. Background technique [0002] In the prior art, processing the original ashes of thermal power plants, that is, dry ash, into commercial ash, that is, fly ash that meets national standards, is currently a major way for coal-fired power plants to carry out comprehensive utilization of fly ash. In the past, the powder separation equipment used in our country has small processing capacity, low adjustment and classification efficiency, and it is difficult to adapt to fly ash separation of different processes. In 200620050408.0, an adjustable forced eddy current fly ash separator is disclosed. The forced eddy current generated by the impeller of this fly ash separator can only separate the fly ash once, the classification effect is not good, and the structure of this equipment is complicated , manufacturing is difficult, in order to ...

In the past, the powder separation equipment used in our country has small processing capacity, low adjustment and classification efficiency, and it is difficult to adapt to fly ash separation of different processes

In 200620050408.0, an adjustable forced eddy current fly ash separator is disclosed. The forced eddy current generated by the impeller of this fly ash separator can only separate the fly ash once, the classification effect is not good, and the structure of this equipment is complicated , manufacturing is difficult, in order to obtain fly ash with different particle sizes, the equipment needs to be adjusted, but the adjustment method is not easy to operate, which is the deficiency of the existing technology
