Embodiment

[0050] (1) Preparation of finished product puree:

[0051] (1.1) Put the iron tailings into the grinding mill and grind until the fineness of the iron tailings is 0.09 mm;

[0052] (1.2) Discharge the milled iron tailings and wet ash mixture in the ratio of 4:1 into the first mixing tank for stirring and mixing to make primary puree; The fine ash collected in the air is a kind of solid waste in the factory area. When cleaning, it needs to be treated by spraying method, which is the wet ash discharge method, and the discharged liquid is the wet ash discharge mixture. The ratio between water and fly ash is 1:20;

[0053] (1.3) Add the adjusted pulp to the primary raw pulp to obtain the finished raw pulp, the mixing ratio between the primary raw pulp and the adjusted pulp is 9:1, and stir the finished raw pulp until the diffusion degree is 30cm; the adjusted pulp includes ;The industrial waste liquid is discharged into the sedimentation tank, and after filtration and sedimentat...

Abstract

The invention relates to a processing method of a high-strength iron tailings aerated concrete block, which includes the preparation of finished product raw slurry: batching and pouring: curing and molding; the processing method of the high-strength iron tailings aerated concrete block can obtain production conformity The use of iron tailings concrete blocks with the highest strength requirements and the best strength performance realizes the comprehensive recycling and reuse of industrial wastewater, fly ash, and iron tailings; it is not the traditional mixture of iron tailings, fly ash, cement, and gypsum , but the iron tailings, wet ash mixture and conditioning pulp are firstly prepared as finished raw pulp, so that the iron tailings, wet ash and wastewater generated in the production can be discharged in real time and prepared for storage, and when it is necessary to prepare When making bricks, the prepared raw slurry can be extracted immediately without waiting, which improves the efficiency of waste recycling and block preparation, and simplifies the preparation process of iron tailing concrete blocks.

Description

technical field [0001] The invention belongs to the technical field of iron tailings recovery and reuse, and in particular relates to a processing method for high-strength iron tailings aerated concrete blocks. Background technique [0002] Iron tailings aerated concrete is a new type of building material prepared with iron tailings as the main raw material and aluminum powder as an air-generating agent; there are abundant raw materials for the production of aerated concrete in China, especially iron tailings as raw materials, which can be integrated Utilizing industrial waste, controlling environmental pollution, and not destroying cultivated land can create good social and economic benefits; thereby improving the performance of aerated concrete; in recent years, iron tailings have been used to replace fly ash and river sand as the basic silica Air-entrained concrete prepared from high-quality raw materials has been widely used. Based on the utilization of iron tailings at ...
