Description
Technical Field
The invention relates to the technical field of mineral separation, in particular to a pulp separator.
Background
As is known, in industrial mining, a gravity separation technology is often used for separating metals with large specific gravity, and a disk rotary vibration ore dressing bed utilizes the automatic rotation of a disk, so that heavy minerals attached to the surface of the disk are brought out of an ore pulp settling area and enter an enrichment area under the drive of friction force. Under the impulsive force of water, the layer of light mineral on the surface of the heavy mineral is washed away. The heavy minerals are left behind and recovered. The advantage of the disk-type rotary vibratory separator is that the heavy minerals that settle on the disk surface in the slurry settling zone in time are moved to the mineral enrichment zone in time rather than being retained in the score channel as in the shaker and being disturbed by newly added mineral particles. The technical disadvantage is that the diameter of the disk vibratory concentrator is approximately 4 meters or so, and the manufacturing and transportation costs of the disk are very high.
A silt centrifuge similar to the present invention is: the invention discloses a sludge-water separation device, which is disclosed in Chinese patent application publication No. CN112876029A of No. 01/06/01/2021.A thin pulp chamber, a thick pulp chamber and a main shaft assembly are arranged above a centrifugal cylinder, the technology uses the centrifugal cylinder which rotates at a high speed to discharge thick pulp which carries mud with higher specific gravity in thick pulp water from a thick pulp outlet channel of a thick pulp chamber under the action of centrifugal force and water power; the slurry with the silt with smaller specific gravity and particle size enters the slurry chamber and is discharged through the slurry outlet channel, so that the separation of the thick slurry and the thin slurry is achieved. The technical design has the idea that the centrifugal cylinder does not rotate, and slurry needs to be driven by an impeller to rotate; but the friction resistance between the slurry and the centrifugal cylinder is very large, so that the working noise is high, the heating energy consumption is higher, and the problems of complex structure, inapplicability to ore pulp separation of ore dressing and the like exist.
