Abstract
Description
Technical Field
[0001] This utility model relates to the field of flotation clean coal technology, specifically a separation mechanism for flotation clean coal. Background Technology
[0002] Flotation coal preparation (flotation clean coal) separates coal slime in an aerated coal slurry based on the surface wettability of particles. Specifically, coal particles have hydrophobic surfaces, while gangue has hydrophilic surfaces. Due to their hydrophobic nature, coal particles easily float towards air bubbles; while due to their hydrophilic nature, gangue particles are less likely to be trapped by air bubbles. Therefore, this difference in properties can be used to achieve effective separation of coal and gangue.
[0003] In general, when separating clean coal, air is injected into the coal slurry to form a large number of bubbles, which fully mixes the coal slurry and bubbles, increasing the chance of collision between coal particles and bubbles. During the flotation process, hydrophobic coal particles adhere to the bubbles and rise to the surface of the coal slurry with the bubbles, forming flotation foam. Meanwhile, hydrophilic gangue particles remain in the coal slurry and do not rise with the bubbles. They seep out to both sides of the separation box, thus obtaining flotation clean coal. Flotation foam is continuously generated, and it is difficult to collect the flotation foam in the middle, resulting in low efficiency.
[0004] To address the above issues, a separation mechanism for flotation of clean coal is proposed. Utility Model Content
