Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings of the specification, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0023] Such as figure 1 As shown, a kind of recycled solid waste is used in the mixing production line before sintering, including ash mixing workshop, mud mixing workshop, and mixing workshop. The ash mixing workshop conveys the dedusted ash with quantitative output to the mixing plant through a scraper conveyor 4 Workshop, the mud mixing workshop transports the quantitatively output mud to the mixing workshop through the mud conveying pipeline 6.

[0024] The ash distribution workshop includes ash conveying pipe 14, ash silo 1, quantitative feeder 2, screw scale 3, scraper conveyor 4. The input end of the ash conveying pipe 14 is temporarily connected to the dust tanker 15, and the output end of the ash conveying pipe 14 is conn...

Abstract

The invention provides a uniform mixing technology of recycled solid wastes before sintering, and a production line thereof. Various solid wastes are intensively processed to prepare a uniformly mixed material with suitable water content, homogenous components and single kind, so the stability of products in the reutilization of solid wastes is guaranteed. A uniform mixing production line of the recycled solid wastes before sintering comprises an ash distribution workshop, a slurry distribution workshop and a mixing workshop, the ash distribution workshop conveys quantitatively outputted dedusted ash to the mixing workshop through a scraper plate conveyor, the slurry distribution workshop conveys quantitatively outputted slurry to the mixing workshop through a sludge conveying pipeline, and the strong mixer of the mixing workshop strong stirs ash and slurry to form a bulk uniformly-mixed material used as a standby sintering material. Compared with the prior art, the technology and the production line have the advantages of individual recovery and comprehensive utilization of solid wastes generated in every process in the metallurgical industry, production cost reduction, and environment protection reaching.

Description

Technical field [0001] The invention relates to the technical field of sintering in the metallurgical industry, in particular to a mixing process and a production line of recycled solid waste materials before sintering. Background technique [0002] Various processes in the metallurgical industry (stockyard, sintering, pelletizing, coking, ironmaking, steelmaking, steel rolling) produce solid wastes such as dust removal ash, dust removal sludge, and pump pit sludge, which contain useful elements such as Fe, Ga, Mg, and C. Can be used twice. In the prior art, when various solid wastes such as dust removal ash, dust removal sludge, and pump pit sludge are reused, the various solid wastes are usually simply mixed and then put into the sintering process. However, because the quantity, moisture and composition of various solid wastes are not the same, it is easy to produce mud compaction during the mixing process, which seriously affects the production process of iron ore powder aggl...
