Abstract
The invention relates to a mixing mill applied to a fly ash curing system. The mixture of chelating agent and water and fly ash are conveyed to a front section of a milling box by a feed device; a milling shaft rotates to drive a delivery blade to rotate and the delivery blade conveys the mixture of chelating agent and water and the fly ash to a middle section of the milling box; the milling shaft drives a milling blade to rotate so as to complete full mixing, stirring and squeezing of the mixture of chelating agent and water and the fly ash for complete reaction and heavy metal in the fly ash is then cured; the milling shaft comprises two shafts which rotate in the same phase to complete the process; a reverse blade and the milling blade rotate in opposite directions to ensure that milled fly ash is shaped by being squeezed; in addition, passing through forming dies, the products of the mixture of chelating agent and water and the fly ash through full reaction form granulated solid mixture to be processed with the next procedure and then conveniently done with landfill disposal or treatment.
Description
Technical field
The present invention relates to the flying ash process field, particularly relate to a kind of flyash solidification system for mixing roll.
Background technology
Along with China's rapid development of economy, the output of municipal solid wastes is increased sharply.Since destructive strong, the volume of organic toxicity of municipal solid wastes subtracted hold obviously, advantage such as energy recovery, the burning electricity generation technology has become the important development direction of some soil anxieties of China, big city disposal of refuse that the municipal solid wastes organic principle is high at present.But municipal solid wastes burns flying ash that the back produces wherein enrichment the pollutants such as heavy metal of the easy diafiltration of high concentration, be regarded as danger wastes, for reducing the secondary pollution that flying ash causes environment, must carry out appropriate processing to it.Thereby flyash curing system has obtained extensive use, generally all comprises storage bin for flyash in the flyash curing system, and storage bin for flyash plays temporary transient storage flying dust, and stable flying dust supply is provided, and satisfies the needs that follow-up flyash curing is handled.
