Description

Technical Field

[0001] The present invention relates to the technical field of mixing equipment, and specifically to a device for preparing an ecological cement-based iron tailings mixture. Background Technique

[0002] As a raw material for roadbed construction, iron tailings can not only solve various problems caused by the large-scale storage of iron tailings, but also solve the problem of the large demand for raw materials in road construction. Since the particle composition of iron tailings sand is generally relatively fine, belonging to fine sand, and the roadbed is required to bear a high load, during the roadbed compaction process, the iron tailings sand does not form a binding force, which is prone to particle flow and difficult to be compacted, and the strength cannot meet the requirements. Therefore, in the process of roadbed construction, some inorganic binders are generally used to mix the iron tailings and the inorganic binder evenly to form roadbed materials.

[0003] Due to the limited mixing range of the mixing shaft of the existing mixing device, if the mixing effect is to be ensured, the diameter of the mixing tank should not be too large, which results in less roadbed material that can be prepared by the mixing tank at one time and low preparation efficiency. Therefore, in view of the above situation, there is an urgent need to develop a device for preparing an ecological cement-based iron tailings mixture to overcome the deficiencies in current practical applications. Summary of the Invention
