Embodiment 1

[0057] A specific embodiment of the present invention discloses a separation and recovery process for tailings (hereinafter referred to as raw ore) of a certain molybdenum industry using the above-mentioned hydraulic flotation equipment, wherein the thickness of the perforated plate is 2mm, and the separation and recovery process Including the following steps:

[0058] Step 1: Add foaming agent MIBC (20ppm) to the water-air mixture in advance, adjust the ratio of the water velocity and gas velocity of the water-air mixture injected into the annular cavitation device 7, form an ascending water flow, and generate cavitation bubbles;

[0059] Step 2: Put the raw ore pulp into the hydraulic flotation machine 2 from the feed pipe 4, the coarse coal slime in the pulp completes the interference settlement in the hydraulic flotation machine, and the coarse grain concentrate is discharged from the overflow port of the hydraulic flotation machine 2 discharge; the coarse gangue in the co...

Abstract

The invention relates to hydraulic flotation equipment and a dredging method thereof, belongs to the technical field of beneficiation equipment, and solves the problem that in the prior art, tailingsof hydraulic flotation equipment are jammed and blocked, and timely discharge of the tailings is affected. The hydraulic flotation equipment comprises a hydraulic flotation machine, a lifting device and a jam dredging mechanism, wherein an overflow groove is formed in the upper part of the hydraulic flotation machine, the lifting device is arranged at a cover top of the overflow groove, the jam dredging mechanism comprises a striker rod and a striker head, one end of the striker rod is connected with the lifting device, the other end of the striker rod is connected with the striker head, and the jam dredging mechanism can move up and down and rotate in a self-rotating mode under driving of the lifting device. According to the hydraulic flotation equipment, the separation efficiency and theseparation effect can be improved, and jammed tailings can be efficiently and rapidly dredged.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a hydraulic flotation equipment and a dredging method thereof. Background technique [0002] Hydraulic flotation equipment is a kind of mineral processing equipment suitable for coarse particle separation. During the flotation process, the pulp concentration is high and the particle size is large. During the formation of the bed, it will gradually accumulate at the bottom of the tailings tank, resulting in the tailings tube The plug is not smooth. The current commonly used technology is to install a recoil water device at the bottom of the tailings pipe, and the recoil water impacts the bottom of the tailings tank and blocks the coarse-grained pulp in the tailings pipe, so that the pulp blocks are loosened and dredged. However, the backwash water pressure of the backwash water device is small, it is difficult to penetrate the thick coarse mineral layer with ...
