Description

Device and method for anti-tipping clamping groove type traction thickener

Technical Field

The invention relates to the technical field of concentration in a concentrating plant, in particular to a device and a method for an anti-tipping clamping groove type traction thickener.

Background

At present, because the ore grade of many open-pit mines, especially open-pit iron mines, is higher and generally reaches between 45% and 55%, the grade of the part of open-pit mines can be improved to between 58% and 65% only by simple crushing-ore washing or crushing-ore washing-gravity separation or large-particle size pre-selection, so that iron ore concentrate with better quality can be obtained for sale.

Since current surface mines, particularly large surface mines, typically consist of multiple mine segments, the mining area is constantly changing even in the same segment. Most of the open-pit iron ores are constructed in a fixed separation plant, and then raw ores mined from all ore sections are conveyed to the separation plant for treatment. In the mode, the distance between the selected factory and the stope is very long, so that the construction cost and the transportation cost of a transportation road of the raw ore are increased; and the fixed type selecting factory is difficult to be repeatedly utilized in other mines after the mine service is finished, so that the sinking and the waste of assets are caused.

Therefore, it is desirable to construct a fully mobile modular beneficiation plant, in which each operation unit of the beneficiation plant is disposed on each mobile carrier, so that each operation of beneficiation can be disposed nearby a mining area, and beneficiation modules are continuously moved along with changes of the mining area. Therefore, the transportation cost and the transportation road cost of the raw ore can be reduced to the greatest extent, and the modularized movable ore dressing module can recombine each operation and move to other mines for continuous service after the service life of the mines is over, so that the ore dressing facility is recycled, and the repeated investment of the ore dressing facility is avoided.

But for the modularized selecting factory in the flow of crushing-washing ore or crushing-washing-gravity separation or large-particle size pre-selection, because slime is generated in the flow, the slime needs to be concentrated to realize the backfill of the mining pit by the slime and the recycling of overflow water. But the concentrator is limited by its annular configuration and large diameter, and there is currently no suitable modular mobile installation. Due to the difficulty of modularization movement of concentration operation, the concentration plants of open-pit rich mines with a plurality of current processes of crushing-ore washing or crushing-ore washing-gravity separation or large-particle size pre-concentration have not been constructed in a modularization way.

The concentrator has large area, a single point is stressed movably, and the moment of stress point is too large, which can cause the damage of the concentrator tank body, so that the stress area needs to be increased as much as possible when the concentrator is moved. And the weight distribution on the thickener tank body is uneven, and the thickener is prevented from tipping when in moving.

Therefore, there is a need to develop a mobile modularized concentration facility with simple structure and convenient movement to promote the construction of a full-modularized mobile concentration plant suitable for an open-air iron-rich mine, thereby reducing the raw ore transportation cost and the road construction cost and realizing the reutilization of the concentration facility.
