Abstract

The invention provides a tailings dehydration performance detection device based on a rheometer and a use method of the detection device, and belongs to the technical field of paste filling tailings concentration. The device comprises a computer, a connecting line, the rheometer, a transmission shaft, a connecting device, a water guide rod, a cylindrical material containing barrel and an experimental material, wherein one end of the transmission shaft is connected with the rheometer, the other end of the transmission shaft is connected with the water guide rod; the transmission shaft and the water guide rod are connected by the connecting device; the transmission shaft, the connecting device and the water guide rod jointly form a dehydration rake frame, wherein the dehydration rake frame is placed in the cylindrical material containing barrel; the experimental material is arranged in the cylindrical material containing barrel; and the rheometer is connected with the computer through the connecting line. The device is simple in processing, relatively low in manufacturing cost, and simple to operate and high in intelligence; and the enterprises, colleges and research institutes withthe rheometer can perform quick implementation, and the monitoring indexes are comprehensive and efficient. Theoretical research and technical support can be provided for various mine enterprises forproducing tailings, such as colored, black, noble metals, rare metals, gold and the like.

Description

technical field [0001] The invention relates to the technical field of paste filling tailings thickening, in particular to a rheometer-based tailings dehydration performance detection device and a use method. Background technique [0002] Paste filling mining technology is the most cutting-edge filling mining technology at present. It has the advantages of environmental protection, economy, safety and high efficiency. It is one of the hot research technologies in the field of mining at home and abroad in recent years. After years of research and practice, this technology has been successfully applied to many metal mines in my country. [0003] Tailings thickening is an important process of paste filling. Generally, the tailings of the dressing plant are directly pumped into the deep cone thickener for a stage of dehydration. During the entire dehydration process, the most critical is the dehydration concentration and the internal rake torque of the thickener. Because the t...
