Problems solved by technology

However, the one-stage continuous dehydration technology is easy to be raked, the storage time is short, and the dehydration effect for ultra-fine tailings is not ideal, while the two-stage intermittent dehydration technology has high energy consumption and discontinuity, which affects the continuous disposal process

Abstract

The invention provides a two-section type continuous, rapid and deep dehydration system for full tailing slurry, and belongs to the technical field of mine tailing filling. The system comprises a tailing flocculation and sedimentation bin, a deep dehydration and activation storage bin and a deep dehydration and activation system. The deep dehydration and activation system is located in the deep dehydration and activation storage bin. The tailing flocculation and sedimentation bin and the deep dehydration and activation storage bin are connected through an underflow conveying pipe and a high-pressure water pipe. A driving rod of the deep dehydration and activation system is flexibly connected with a dehydration and activation harrow frame through a connecting device, the dehydration and activation harrow frame is flexibly connected with an underflow discharging harrow frame through a connecting device, and the circular motion of the driving rod drives the dehydration and activation harrow frame and the underflow discharging harrow frame to rotate. The dehydration system not only can realize rapid and deep dehydration of full tailing slurry and meet the requirement of tailing disposal on concentration, but also can perform storage for a long time, can ensure the continuity of the dehydration process and meets the requirement of continuous and stable production.

Description

technical field [0001] The invention relates to the technical field of mine tailings filling, in particular to a two-stage continuous, rapid and deep dewatering system for full tailings slurry. Background technique [0002] The rapid development of the metal mining industry is an important support for the country's industrialization and rapid economic development, but it also brings serious safety and environmental problems, namely the huge safety hazards of underground goafs and the safety and environmental problems of surface tailings ponds. With the continuous development of metal ore mining technology, paste filling technology has been widely used in the coordinated management of tailings ponds and goafs all over the world because of its advantages of safety, environmental protection, economy and high efficiency. One of the key technologies for green disposal and green mining of underground metal mines. Efficient and deep dehydration of full tailings is the key to paste...
