Problems solved by technology

[0002] A steel factory produces a large amount of metallurgical solid waste such as desulfurization ash and steel slag every year. There is no large-scale development and utilization, and the long-term land occupation and stacking not only occupies a large amount of open space, but also causes serious environmental pollution.

Embodiment 1

[0019] The special curing agent in this embodiment is prepared by mixing the following raw materials in parts by weight: 5-10 parts of coking desulfurization ash, 10-35 parts of slag powder, 20-30 parts of steel slag powder, and 20-30 parts of activator. The activator uses sodium silicate and sodium hydroxide, and the weight ratio of sodium silicate and sodium hydroxide is 1:3~5.

[0020] Coking desulfurization ash, slag powder, and steel slag powder are transported by tanker respectively, and transported to No. 1 raw material bin 1, No. 2 raw material bin 1, and No. 3 raw material bin 3 through pneumatic conveying devices. No. 4 raw material warehouse 4 and No. 5 raw material warehouse 5. Coking desulfurization ash is measured and weighed, conveyed to the primary mixer 11 by a screw conveyor, slag powder is measured and weighed, and conveyed to the primary mixer 11 by a screw conveyor, steel slag powder is measured and weighed, and conveyed to a primary mixer by a screw conve...

Abstract

The invention provides a device and method for producing a special curing agent. The device for producing the special curing agent comprises a plurality of raw material bins, spiral weighing scales, afirst-level mixer, a second-level mixer, a bucket elevator II and a bucket elevator I, the spiral weighing scales are arranged at the bottoms of the raw material bins, the raw material bins feed materials to the first-level mixer through the spiral weighing scales, and the remaining raw material bins feed the materials to the second-level mixer through the spiral weighing scales; and the first-level mixer feeds the materials to the second-level mixer through the bucket elevator, and the second-level mixer feeds the materials to a finished product warehouse through the bucket elevator II. Compared with the prior art, the device and method for producing the special curing agent have the beneficial effects that metallurgical solid waste from a steel plant can be utilized to produce the high-efficiency, environment-friendly and low-cost special curing agent suitable for geotechnical engineering and rapid mud solidifying construction application and are widely used in engineering application such as mine filling and roads, the problem of disposal of the solid waste such as desulfurization ash and steel slag in the steel plant is solved, and the full quantitative treatment of the solidwaste is gradually realized.

Description

technical field [0001] The invention relates to the field of metallurgical solid waste recycling and reuse, in particular to a device and method for producing a special curing agent. Background technique [0002] A steel factory produces a large amount of metallurgical solid waste such as desulfurization ash and steel slag every year. There is no large-scale development and utilization, and the long-term land occupation and stacking not only occupies a large amount of open space, but also causes serious environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a device and method for producing a special curing agent. The present invention utilizes metallurgical solid waste from a steel plant to produce a special curing admixture product locally as an urgently needed raw material in engineering construction and mine filling. Form a new type of non-steel industry. [0004] To achieve the above object, the present inventio...
