Embodiment Construction

[0012] As shown in the figure, the ceramic filter 5, the overflow pool 4, the thickening tank 1, the underflow pump 2 and the distribution barrel 3 form a slurry dewatering circuit, which is the prior art. When the ore slurry is magnetic, switch the valve 6 to make the ore slurry enter the overflow pool 4 first, open the backflush valve 11 of the ceramic filter, and backflush the ceramic filter, and the backflush water enters through the overflow pipe 12. Overflow collection tank, after the ore slurry in the overflow collection tank is diluted, it enters the thickening tank 1 for precipitation and overflow. While backflushing the ceramic filter, close the pipeline between the concentration tank and the underflow pump, open valve 7, and backflush the underflow pump. The time for backflushing the ceramic filter and the underflow pump is 8- After 10 minutes, after the ceramic filter and the underflow pump backflush, they connect the pipeline between the thickening tank and the und...

Abstract

The invention relates to a dehydration method of high magnetic ore pulp, which can effectively solve the problems of pipeline blocking and difficult demineralization caused by the high magnetic ore pulp. The technical scheme is as follows: ore pulp flows into an overflow collection tank firstly, water backflushing is carried out on a ceramic filter so as to dilute the ore pulp in the overflow collection tank, and then the diluted ore pulp enters into a concentration tank for sedimentation and overflow.

Description

Technical field [0001] The invention relates to a dehydration method of high magnetic ore pulp. Background technique [0002] In the prior art, the ceramic filter, the overflow pool, the thickening tank, the underflow pump and the distribution bucket form a slurry dewatering circuit. After the slurry reaches the terminal dehydration station, it first enters the distribution bucket, and then is distributed to the ceramic filter by the distribution bucket. For dehydration, the slurry and cleaning water overflowing from the ceramic filter enter the thickening tank to settle through the overflow pipe, and the increased concentration of the slurry is transported to the distribution barrel 14 through the underflow pump to increase the overall concentration of the slurry entering the ceramic machine. In the normal transportation process, the dressing plant needs to demagnetize the pulp, and the demagnetized pulp is beneficial to pipeline transportation and dehydration. However, if the ...
