Title: Rake-free thickener with three sections of discharge openings
Inventor: WEI ZHOU
IPC: B01D21/24
Filed: 2020-02-17
Abstract: The invention relates to the field of thickening treatment of coal slime, and more particularly, to a rake-free thickener with three sections of discharge openings. The three-section discharge rake-free thickener of the invention includes a center-section thickening tank and two side chamber-section thickening tanks. A “one-center and twoside” discharge mode is adopted. Coarse and fine particles are discharged and recycled from different openings. The coarse particles are discharged from a center underflow opening. The fine particles are discharged by being sucked upwards from side chamber underflow openings. A fine fraction extreme horizontal movement distance is 3 times a radius of the tank. The settling time is longer. A tank bottom of the thickening tank is in a large-dip-angle cone shape. Materials slide to the underflow openings by self-weight. No rake is needed during the discharge. The phenomenon of rake pressing is completely solved. The whole thickening operation achieves higher thickening efficiency. The thickener works more reliably and stably.
