Flotation feeding material pretreatment apparatus and method for integrating flotation feeding material pretreatment apparatus and flotation machine

Abstract

The invention provides a flotation feeding material pretreatment apparatus and a method for integrating the flotation feeding material pretreatment apparatus and a flotation machine. The flotation feeding material pretreatment apparatus comprises a material inlet pipe, a slurry adjusting groove, a stator, a blade wheel, an agent inlet pipe, a bush, a bearing seat, a transmission shaft, a driving mechanism and an overflow plate, wherein the material inlet pipe adopts a tee structure and is provided with two outlets, various components are sequentially fixed, and the rear wall of the slurry adjusting groove is provided with a rectangular hole as the material outlet of the pretreatment apparatus. The method for integrating the flotation feeding material pretreatment apparatus and the flotation machine comprises that the pretreatment apparatus adopts a square structure design and has the same width as the flotation machine, the overflow plate of the pretreatment apparatus is more than 100mm higher than the overflow weir of the flotation machine, and the material inlet hole of the flotation machine and the material discharge hole of the pretreatment apparatus adopt the same width rectangular hole design. According to the present invention, the ore slurry pretreatment process is strengthened, the flotation agent consumption is effectively reduced, the selectivity of sorting is improved, and the apparatus has advantages of high ore slurry throughput, small occupation area, low processing cost, low civil construction cost, high integration, convenient production management, low use cost and low maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of flotation equipment, and in particular relates to a flotation feeding pretreatment device and a method for integrating it with a flotation machine. Background technique [0002] Flotation technology is the most economical and effective separation method of fine coal slime, and it is also an important method for deep separation of coal. With the improvement of coal mining mechanization, the amount of pulverized coal in the raw coal of the coal preparation plant is increasing, and the flotation operation becomes more and more important. Moreover, the flotation operation is also an important link in the slime water treatment system of the coal preparation plant, which plays an important role in realizing the closed circulation of the slime water and environmental protection. [0003] The flotation feed must have a suitable and stable concentration, and some chemicals must have a certain contact time with th...

Problems solved by technology

[0004] At present, domestic common pulping equipment mainly includes mixing tanks, pulp preparers, and pulp preprocessors. Large, high energy consumption of the system; in addition, the pulping equipment and the flotation machine are two independent equipment, which are connected through pipelines and work independently during production. The user's use cost and maintenance cost are relatively high. The defect of convenience can no longer meet the needs of efficient development of mineral resources and social and economic development
